But solar panels can be… finicky. They aren’t always designed to endure the rigors of the great outdoors. (And, frankly, some of them simply don’t work as well as they should.) Unlike the large, heavy solar panels you might install on the roof of your home, RVers need panels that are either compact enough to fit on a vehicle, or portable enough to stow inside. A great RV solar panel, whether foldable or fixed on the roof, needs to deliver effective energy production and feature a rugged design that can handle dust and rain. If you’re packing up and hitting the road this summer, we recommend pairing your solar generator with a set of the best RV solar panels.

The Best RV Solar Panels

• Best Overall: Renogy 200W 12-Volt Solar RV Kit
• Best Value: Eco-Worthy 100W Solar Panel
• Best Mounted: Go Power! Overlander 190W Solar Kit for RVs
• Best Lightweight: Renogy Flexible Monocrystalline RV Solar Panel
• Best Premium Portable: Bluetti PV350 Solar Panel

The Expert: I’ve used portable solar panels about as extensively as is humanly possible. I relied on them for five years to power my remote work setup through some 40,000 miles of road-tripping all across North America. That work included reviewing solar panels, portable power stations and other relevant gear for leading publications like Popular Mechanics , Popular Science , The Daily Beast and Thrillist , among others.

What to Consider in a Set of RV Solar Panels

Solar panel materials are most frequently made from using silicon crystal, which captures solar energy. These panels come in one of two types: Monocrystalline silicon panels are made with a single panel of crystal, while polycrystalline panels are constructed from multiple crystal fragments. Monocrystalline panels are more efficient because it’s easier for electricity to move through an unbroken crystal. Given that, all of our recommendations are monocrystalline panels.

They can also largely be divided by whether they have a rigid or flexible structure. Rigid panels are a great option for flat-topped RVs, but if your rig has a curved or uneven rooftop, you may want the surface-hugging malleability of a flexible option. Both types are available with similar levels of weather resistance, though rigid panels often take a slight edge when it comes to efficiency of energy production.

Panel Placement–Portable or Mounted?

Before you buy your panels, consider where and how you plan to set them up. You want them to face the sun as directly as possible, for as long as possible. How you position your panels will vary quite a bit, depending on whether you use mounted or portable panels.

With an RV, you have the option to mount your panels directly on your vehicle. A rigid, mountable panel will be more durable than a portable set, water- and windproof to brave the elements, but they require some elbow grease to install. You may also find yourself unable to park in an ideal spot to catch the sun, limiting your capture capacity for the day.

They tend to sit face-up on the roof and aren’t adjustable, so you’ll have a narrow window for maximum efficiency. On the other hand, your rooftop panels will capture energy while you drive, so they’ll draw power for a larger portion of the day.

Portable solar panels are more flexible, literally and figuratively. They fold up for compact storage, and are designed to be easy to set up and tear down. They often have integrated kickstands and handles to help you optimize your placement, no matter where you’ve posted up for the night.

That said, you need to be careful to put them away when the weather turns gray: They are scratch-resistant and can handle a light shower, but they’re typically not meant to stay outside around the clock. And unlike rooftop panels, which are bolted in place, you may not feel safe leaving your portable, easily stolen panels out while away from your campsite, meaning you can only generate power while you’re there.

Wattage and Efficiency

A solar panel's wattage specification indicates the amount of power it can produce in one hour. Most RVs and campers can get enough juice to power their appliance and a few electronic devices for a full day from a 100-500W solar panel setup. A slim 100-watt panel will provide enough juice to power a small fridge, a toaster and a coffee maker.

We imagine, though, that most RVers have more gear than that: If you have an electric stove or a large fridge, we recommend using panels that can bring in at least 400 watts. If you have electronics that need regular charging, like your smartphone or laptop , you’ll need to collect extra power for that as well.

Whatever your daily power consumption is, aim for having a system that will produce at least 2-3 times that if you expect to use electricity around the clock for multiple days on end. Every person’s exact power needs will vary. If you aren’t sure what you need, we recommend starting small and upgrading when and if you need to. You can always buy multiple panels, rather than upgrading to a more efficient model.

One thing to keep in mind: Wattage and other specs provided by manufacturers, including those cited in this guide, describe how the panel will work in optimal conditions—a bright, sunny day without a cloud in the sky. More often than not, you will pull less energy than advertised. To get a better sense of what you can actually expect on an average day, check the efficiency rate, which estimates the panel’s capacity to convert sun gathered into usable electricity. The best solar panels operate at 23 percent or higher.

If you go with foldable panels, make sure you can pick them up and pack them up comfortably, because you will be moving them around a lot. Generally speaking, the higher the wattage rating, the heavier the panels: So, while it might seem convenient to rely on a single 400-watt unit, you may be better off setting up two or more panels than setting up and adjusting something that weighs as much as 40 pounds.

How We Selected The Best RV Solar Panels

We picked the best RV solar panels based on years of experience testing and recommending solar gear, including generators and panels. We also researched panel specs and performance, including data and recommendations from specialty outlets like Treehugger and SolarReviews .

In making our selections, we considered many scenarios for RV owners and power setups to present a range of options that work for as many people as possible. Having spent tens of thousands of miles on the road, I've stumbled on more than a few myself. Lastly, we checked consumer reviews for all of these picks to make sure we didn’t accidentally select a panel that looked perfect on paper, but was actually a lemon. These are the best RV solar panels to keep you powered up on the road.

Renogy 200W 12-Volt Solar RV Kit

This kit has everything you need for easy installation on your RV or camper. It’s made specifically for first-time solar panel users, with a straightforward, user-friendly design. For smaller van conversions you’re probably better off with a portable power station, but this is exactly the kit you need for mid-sized vehicles like Sprinter vans or camper trailers and medium-sized RVs where you want the convenience of power going directly to your rig’s battery.

The two 100-watt solar panels are rigid but relatively lightweight at 18 pounds–it never hurts to keep your vehicle weight down as much as possible–and the kit comes with everything you need to mount them. The included charge controller has LED indicators that allow you to monitor charging, which will help you avoid overcharging or, worse, overloading your system. They also alert you to input changes due to weather conditions like rain, clouds, or nightfall.

The aluminum frame panels are UV- and corrosion-resistant to withstand high winds, rain, snow, and blazing heat, so they’ll take just about whatever the elements throw at you. For anyone looking to install their first RV solar panels on their own, this kit is an excellent pick.

Eco-Worthy 100W 12V Solar Panel

There’s nothing fancy about these panels from Eco-Worthy, but that’s kind of the point. They’re exactly what you need if you’re looking to set up solar panels on your RV for as little as possible. They’re the perfect size for mounting via the pre-drilled mounting holes, and you should be able to fit 3-4 of them on most RV rooftops. They come with integrated 35-inch connectors that run into a waterproof junction box, and the whole panel is waterproofed with sealed and tempered glass.

They’re surprisingly durable for such low-cost panels, too. That said, some buyers have reported receiving damaged panels out of the box, which they had to return and exchange. Once you’ve got them on your RV roof, however, they should last for years.

Go Power! Overlander 190W Solar Kit for RVs

This extremely large 12-volt panel draws up to 190 Watts of power to keep any battery charged on long trips, camping, or on the road. It’s a bit heavy–26 pounds–but its anodized aluminum frame and durable tempered glass panels hold up well against rough weather. Customers report easy installation and that the controller maintains power in their RVs even in less-than-ideal conditions like partly cloudy skies and rain.

If you need more power, the company sells an expansion kit that doubles the output. It’s designed for seamless connectivity between your existing solar power system and the panels you want to add for more power. If you need a lot of juice, this is probably the best mounted panel for the job.

Renogy 100W 12V Flexible RV Solar Panel

This bendable RV solar panel is great for uneven surfaces like Airstreams and vans, or propped up facing the sun at your campsite. It weighs just four pounds and can withstand high winds, rain, and snow.

The mounting uses silicone adhesive for permanent installation without any drilling. It can flex up to 248 degrees without any micro-cracks forming, which is handy for hitting the right angle after mid-day.

Customers like the slim profile of these panels and say the output is great for such lightweight panels. These are best suited for small camper set-ups or as expansions to larger RV solar energy systems, as just one or two of these aren’t enough for a large RV with a lot of appliances.

Bluetti PV350 Solar Panel

Bluetti makes some of the best solar gear in the industry, and the PV350 solar panel is an upscale buy that’s worth the investment. It absorbs up to 350 Watts per hour, which is huge for a folding panel. At the same time, it’s remarkably compact, folding down to a compact 35.6 by 24.1 inches for easy storage. There’s a downside, of course–it weighs 30 pounds–which may make it tough to set up. You can’t beat that size-to-wattage ratio, though.

It’s also designed for efficiency. The cells are wired in parallel, rather than in a daisy-chained configuration like you find in most cheaper panels. This allows it to continue collecting power when mostly shaded. (Many panels will stop operating if they aren’t getting very good coverage.)

The PV350 is also extremely well-built. Nick took one on a trip through the deserts of Utah and Nevada, where it saw no shortage of hard treatment from dust, wind and my own rough handling, but emerged without any major damage. That said, it isn’t fully waterproof: You can leave it out through a light drizzle, but avoid charging on rainy days.

Goal Zero Nomad 100

Goal Zero, another well-regarded brand, is known for making tough, outdoor-friendly solar gear for camping. Case in point, the Nomad 100 is perfect for pretty much any camping scenario, whether you’re charging up your RV or a portable power station. Weatherproof and built like a rock, it’s designed with tie-down loops around the frame. These are great for both pegging it into the ground or affixing it to your RV rooftop to keep it in place when the wind kicks up.

The Nomad 100 folds down to a comparatively small 20 x 15 x 2 inches, it’s easy to pack and move around. It draws a solid 100 watts, which is good for its size, but you may need a few of them to fully charge up an RV. To that end, you can daisy chain multiple Nomads without a splitter. That said, its 8mm plug is not universally compatible with all systems and power stations: Many support it, but you may need an adapter if yours has a different port.

Jackery Explorer 2000 Plus Solar Generator Bundle

You see Jackery gear everywhere in the RV/van life scene these days because the brand offers such an expansive variety of dependable solar products. After using many Jackery generators, I found the 2000 Plus brings the perfect balance between physical size and capacity: Its 2000-watt-hour capacity is plenty for most campers, but it isn’t so large that you can’t bring it out when you need it. Weighing a hefty 96 pounds, it isn’t exactly light, but compensates for the heft with integrated wheels and a telescoping handle so you only need to lift it to get it on and off your vehicle. Plus, it has a 25A plug, so it's designed specifically to bring on an RV.

This kit pairs the 2000 Plus with two of Jackery’s 200W SolarSaga panels , which are among the best you can find. They’re very durable—I can’t tell you how hard I’ve worked them over the years. Plus, they fold down to an easy-to-carry package, and are reliable in most sunlight conditions.

And, if you need even more juice at some point, you can expand the 2000 Plus’ capacity with up to five of the brand’s 2000 Plus battery packs , which can store as much as 12,000 watt-hours of power. That’s way more than you’ll ever need on an RV, but it’s always nice to have the option.

EcoFlow 220W Bifacial Foldable Solar Panel

Bifacial panels, which can absorb solar energy using both their front and back face, aren’t as common among portable and RV panels as they are for home setups, but they definitely offer benefits while camping. By capturing solar energy from the light that bounces onto the back of the panel, they can capture more energy and be more efficient when it isn’t placed perfectly.

According to EcoFlow, the second face of their 220W Bifacial Foldable Solar Panel gathers 5-25 percent more energy than a single-sided panel. Personally. I’d say 25 percent is a stretch, but 15 seems in line with my experience and that’s not nothing: Every bit of juice counts when you’re on the road. I found it especially useful for off-season camping, when the days are shorter and you get a narrower window for gathering sunlight.

I also loved this panel’s tent-like stand design, which makes it far easier to set up and place than other folding panels. It’s lightweight–just 20 pounds–but it’s also pretty big and can be tough to lug around.

Q+A With Our Experts

What kind of tools do I need to install a solar panel on my RV?

Much of the work can be done with basic tools you likely already have like a cordless drill , screwdrivers , and wrenches . I’d also recommend keeping a pair of wire cutters and strippers handy, as well as a hydraulic crimper, a MC4 connector/crimper tool, and a digital multimeter . As with any project involving electricity, it’s always a good idea to use dielectric tools that won’t conduct electricity.

Will mounting a solar panel on my RV change how I drive?

It’s unlikely. Typically your panels are more or less flush against the roof, which shouldn’t noticeably alter the aerodynamics of your RV.

Any advice on how to park my RV for great solar panel placement?

Try to park with the front to the east and the rear to the west. This will provide your roof with the maximum amount of sun throughout the day. As an added bonus, if you’ve got a typical left-sided fridge it will keep it somewhat shaded, reducing its power demand. When parked in direct sun, keep your window blinds closed to keep the interior cooler, further reducing the strain on your fridge.

Can I use my solar panel to jump-start my RV?

The short answer is no. The long answer is that the energy collected from a solar panel needs to be converted to a voltage and amperage required by whatever you want to use or charge. Without a charge controller to regulate power flow, and monitor battery charge levels, the current your solar panel outputs won’t be compatible with your RV’s battery.

WindyNation 100 Watt Solar Panel Off-Grid RV Boat Kit

A gimmick or free electricity on the road? We present you with the best solar panels for RV and answer the ultimate question: Are they worth it at all?

When I first saw solar panels slapped on an RV I immediately thought of one of my all-time childhood movies “Race the Sun." It’s about teenagers who build their solar car to race across Australia. 

Now, as a camping and RVing enthusiast, I realize that solar panels can’t power the RV but can make my trip much more convenient and sustainable.

But what sort of problems will solar panels solve in your RV?

Coupled with a capable solar battery, I use them to power the appliances and lighting in my RV. This allows me to camp away from crowded campsites and become fully independent of the grid.

What is more, it allows me to camp sustainably and offset the carbon emissions of my RV by using a renewable source of electricity. 

The 7 Best Solar Panels for an RV or Camper Van (Reviewed by An Electrical Engineer) 

1. renogy 175 watt 12 volt flexible monocrystalline solar panel (best overall).

Wattage: 175 watts | Panel Type: Monocrystalline | Water Resistance: IP67 | Weight: 6.2 lbs

What’s thin as a coin and bends up to 248 degrees? It’s my favorite solar panel for RV on this list. 

The Renogy 175 Watt 12 Volt Monocrystalline Solar Panel has everything I expect from a top-shelf solar panel for RV use. 

It weighs only 6.2 lbs so I confidently fixed six of these to my RV roof. 

What is more, they are extremely flexible, so they’ll adapt to any trailer style. That’s a big consideration for me. 

Scroll down to the Flexible vs. Rigid Solar Panels section to read my opinion, but in short, if you have the budget — go for flex.

The Renogy 175W has great solar efficiency thanks to transparent dots on the surface that capture the sun's rays even when coming at an angle. 

In my use, even on a hazy day on Washington state shore, two of these panels provided well over 200 watts. 

• Extremely flexible
• Ultra lightweight
• Resistant to high winds
• IP68 water and dust resistant
• Anti-scratch surface
• Easy to install
• Mounting eyelets too small
• Connection leads could be longer

Why Do I Like It?

I glued four of these panels to my RV roof while the remaining two are movable — I use mounting eyelets to rig them on the trailer side that receives the most sunlight.

2. BLUETTI PV200 200W Solar (Runner up)

Wattage: 200 watts | Panel Type: Monocrystalline | Water Resistance: IP65 | Weight: 16.1 lbs

Following excellent solar generators like the AC200P and the beastly EP500 , Bluetti strikes back with a formidable portable solar panel kit that can make a perfect RV solar panel system.  

On a bright su nny day, the Bluetti PV200 200W Solar charges my AC200P solar generator in about 5 hours.

If you’re not big on DIY and mounting stuff, you’d be happy to hear that you can get these up and running in less than 30 seconds.

Unfold, connect, and prop it up.

Now, this can be a deal-breaker to some — there are no mounting eyelets or any other way to fix this panel permanently to your RV roof.

I guess you could glue it with silicone or use  EternaBond tape , but since there’s no rim, you’ll have to cover some of the solar cells as well. 

So why is this solar panel on the list at all?

Because not every camper needs a mini solar power plant on the roof. Most users only need to charge a few gadgets like a laptop, camera, phone, and drone. 

These people use portable solar generators and pair them with portable solar panels, which they prop up on a sunny spot, while their RV stays in the shade.  

• High-efficiency panel
• IP65 water and dust resistant
• Super easy to install 
• No mounting eyelets
• Portable use only

Not all places are accessible by RV nor they should be. I can take these solar panels down to the beach and keep the party going.

3. Renogy 100 Watt 12 Volt Flexible Monocrystalline Solar Panel (Best Lightweight)

Wattage: 100 watts | Panel Type: Monocrystalline | Water Resistance: IP67 | Weight: 4.2 lbs

This solar panel for RV is just 0.08 inches thick which is 90% thinner than any rigid solar panel in the 100-watt range. 

The best way to fix this to your RV roof is to use silicone adhesive or EternaBond tape. 

Like on the 175W version, there are six eyelets but they are too small for mounting screws.

So you best use them with rigging cords for non-mobile applications. 

If you want lightweight and reliable RV solar panels that will power your basic devices, you won’t find a better-priced option.

• Easy to install 
• 100 watts might not be enough for some users

These solar panels are just 48 x 21 inches which gives me plenty of options to combine and mount them, either along or across the roof axis.

4. Jackery SolarSaga 100W Solar Panel (Most Versatile) 

Wattage: 100 watts | Panel Type: Monocrystalline | Water Resistance: IP65 | Weight: 9.1 lbs

There’s this thing about Jackery products that make them similar to Apple gadgets:

They are reliable, compatible only with other Jackery products, and have an army of loyal customers. 

The Jackery Solar Saga 100W Solar Panel   is beautifully designed, just like every Jackery product. It  folds in half and has two comfortable carrying handles in case I need to deploy them away from my RV. 

Keep in mind that the Solar Saga is a 100% portable solar panel, just like the Renogy PV200. 

This makes it perfect for boondockers who prefer to keep their vehicle in shade and need to power only a few essential gadgets.

I’ve used two Solar Saga 100W solar panels with my  Jackery Explorer 1000  and after 8 hours of charging I could run a mini fridge for 17 hours. 

Unlike the Renogy PV200, this solar panel for RV comes with four mounting eyelets so you can fix it to your RV roof or side.

Unfortunately, these panels are only compatible with Jackery power stations.

• Super easy to install
• USB ports for direct device charging
• Works only with Jackery solar generators
• Only 4 solar panels can be connected

The Solar Saga 100W comes with USB-A and USB-C cables. In a pinch, I can charge my phone and laptop directly from the panel.

5. Renogy 800W 12V/24V Monocrystalline Solar Premium Kit (Best Premium)

Wattage: 800 watts | Panel Type: Monocrystalline | Water Resistance: IP32 | Weight: 112.8 lbs

Renogy made an offer I could hardly refuse. 

They packed 8 rigid-frame 100-watt monocrystalline panels with the Ro ver 60A charge controller and a Bluetooth module. 

With this kit on your RV roof, you’ll be able to harvest about 3.5-4 kWh of sunlight a day. The panels have a heat-dissipating back sheet that ensures smooth output performance without hotspots.

I was happy to discover that every panel comes with pre-drilled holes in the back frame and Z-brackets for mounting solar panels on the RV roof. When you mount it on the roof, this panel doesn’t go anywhere.

But it was the charge controller that sweetened the deal. If you have a large RV and want every convenience of a mobile home, the Rover 60A allows you to slap another 8 solar panels and boost your system to 1.600 watts! 

Using the Renogy DC Home App I can always check what’s going on there, as the controller sends power data directly to my phone via Bluetooth. 

This way I can always tell how much power is produced, how much I use, and even if there’s something wrong with the system. Pro-level baby!

• 8 x 100W panels
• Solar charge controller
• Bluetooth module
• Automatically detects system voltages
• Compatible with all kinds of batteries
• Rigid-frame panels

Apart from making my RV virtually independent from the grid, these solar panels for RV make a great home outage solution. When the power goes out, just move to your RV and continue whatever you were doing.

6. Topsolar Solar Panel Kit 100 Watt 12 Volt Monocrystalline Off Grid System (Best on A Budget)

Wattage: 100 watts | Panel Type: Monocrystalline | Water Resistance: IP65 | Weight: 15.8 lbs

The price of solar gear is dropping, and now you can get decent RV solar panels for less than $150. 

When I saw the price range of the Topsolar Solar Panel Kit I was suspicious at first. Especially since you get  all the cables, Z-brackets, and — listen to this — a 20A charge controller. 

The heart of this system is a rigid-frame monocrystalline solar panel with a waterproof IP65-rated junction box. 

It means your wiring is completely protected from dust particles and low-pressure water jets.

Still, as with all IP65-rated panels here, you don’t want to leave the junction box or connectors in the rain. 

Remember: The panels are weatherproof but the rest of the equipment are not. 

So why isn’t this solar panel for RV on the top of the list? 

First, I wasn’t aware till I tried it that the charge controller it comes with works only with lead acid batteries. Also, the wiring connectors look and feel flimsy, so I don’t know when I’ll need to replace them. 

And, the screws that hold in the charge controller wires are so tiny and so tight that I can hardly unscrew them without stripping them. 

All in all, with a few tweaks this could be a solid and inexpensive RV solar panel for someone getting into the world of solar power. 

• Very sturdy panel
• Fast charging
• Inexpensive
• Cheap wiring hardware
• Works only with lead acid batteries
• Menu button labeled “Mune”

With a more versatile controller and new wiring, the Topsolar 100W solar panel can be an inexpensive building brick for a full-size RV solar system.

7. WindyNation 100 Watt Solar Panel Off-Grid RV Boat Kit (Budget Alternative)

Wattage: 100 watts | Panel Type: Polycrystalline | Water Resistance: N/A| Weight: 19 lbs

The problem with these low-cost RV solar panels is that they often run out of stock. So if you can’t find a good deal on a Topsolar 100W panel, the next best choice in this category is the WindyNation 100 Watt Solar Panel .

This solar panel is even cheaper and comes with a better 30A charge controller, so you can add more solar panels in the future.

The P30L charge controller that is in the box can handle up to 4 x 100W solar panels in a 12V system and up to 8 x 100W panels in a 24V system.

On the downside, when my panel arrived, it came without any connectors and mounting hardware. 

I’ve emailed customer service and they sent the missing stuff with no questions asked. 

Still, I had to buy at least two fuse holders and fuses (automotive ATC-type will do) and the 30-amp gauge wires to connect the P30L to my battery bank.

• 30A charge controller included
• No water and dust resistance
• No fuse holders included

If you want to stick a couple of solar panels on your RV roof that will survive whatever weather throws at them and still have enough money for the next 3 road trips, these are the panels for you. Just keep that electric gear tucked inside.

7 Best Solar Generators For RV: Reviews & Buyer’s Guide

What Are RV Solar Panels?

RV solar panels are similar to home solar panels. But instead of powering your home, they use the power of the sun to charge your RV battery. 

When your RV is on the road or parked in a sunny spot, the solar panels on the roof absorb energy from the sun. 

Then you can use the RV battery to power lights and small appliances in your camper.

If you add more batteries that the solar panels can charge, you have more electricity available when camping. 

Do You Need To Use RV-Specific Solar Panels?

Whatever vendors want you to believe, there is no such thing as solar panels that are strictly for RV use. Many companies market their products as RV solar panels but only because those panels are suitable for RV use. 

These include both portable solar panels which have multiple ways of permanent or semi-permanent attaching to your RV roof as well as flexible solar panels that you can fix to curved surfaces. Flexible solar panels are a bigger investment but provide a higher ROI with high-efficiency rates. 

I also want to say that solar panels are not a magic pill. 

Not so Free Energy

This “free” and clean power sounds much better than the fuel generator. 

But when I say free I mean the sunshine. The hardware can be quite expensive. Sure, prices of solar equipment have gotten a bit more reasonable in recent years, but if you want quality, you still need to pay a hefty sum.

You need a couple of pairs of 100-watt panels and deep-cycle solar batteries to store power and charge the controller that keeps them from overcharging. Then there’s the inverter that turns the DC power into AC power that most appliances use.

When you add those up, you can be looking at a $1,500+ investment up front.

Also, collecting solar power is much more complicated than hooking up to shore power at a campsite. You need to know how much power you'll need on a daily basis and size your system accordingly. 

No Shade Where I’m Going

It also means you’ll have to park in full sunshine for most of the day. In other words, you can forget about parking your RV in a nicely shaded campsite where you can throw a barbie and pass a few cold ones. 

Don’t get me wrong, solar power is great and worth the investment, especially if you like to boondock on public land away from the grid. 

It’s just that for the most part, if you want the maximum power, you need to:

• Open your wallet
• Leave your rig in the blistering hot sun

Are Solar Panels Worth It? Opinions of An Electrical Engineer

How Much Energy Do You Need for an RV?

First, you need to know how much energy you use in your RV in a day. There are two ways to do this. The first one is easier and the second one is free.

1. Use a battery meter

The easiest way to tell your daily consumption is to install a battery meter like this Renogy 500A Battery Monitor . Before installing solar panels, go camping without hookup charging along the way and the monitor will give you the amount of energy you use with ±1% accuracy. 

2. Calculate your energy use

This way is 100% but requires a bit of math and planning. In short, you need to find out what each appliance or device in your RV consumes and multiply that by the number of hours you expect to use it. 

For example, you have one TV that consumes 100 watts. You guess that you’ll watch TV for about 2 hours per day. So 100W x 2h = 200Wh a day.

You can do the same for every electrical device you want to power while you’re boondocking and you’ll get a rough estimate of the total watt-hours you need. Add a 20% for safety and from there you can estimate how many panels you need. 

If you plan to cook outside and only use electricity for things like lighting, TV, and charging your phone or laptop, two or three 100W solar panels and a 1,200Wh battery will do.

However, if you want to power your fridge or AC you’ll need more panels and batteries. 

How Many Solar Panels Do I Need For My RV?

Now when you’ve measured or calculated the amount of energy you need daily, there is one more thing to consider:

How much energy do solar panels provide to your battery?

You need to achieve a balance here. 

Install too many solar panels without enough battery storage and you're wasting both money and energy that can’t be stored nor used. 

On the other hand, slap one solar panel and a row of batteries, and you won't be able to charge them all while the sun's up. 

Let’s now calculate energy generation and storage needs.

For example, a high-end 100W solar panel will generate an average of 350Wh per day. Keep in mind that this varies by location and time of year. 

You also need to know how many batteries you need to store the power that your RV solar panels generate. One 100Ah 12V battery has about 1,200Wh storage capacity. 

I say it again: Your solar panels for RV will only give you the listed number of watts under perfect conditions.

Perfect conditions = direct sun shining directly at the panel 

On a rainy day, you’ll be lucky to get 100 watt-hours from your 100W solar panels. The same goes for parking in the shade. 

It’s also challenging to estimate the amount of energy you’ll use in a day because days are different. One day you might be outside from dawn to dusk, enjoying nature, hiking, canoeing, and whatnot. The next day might be rainy and you’ll stay inside your RV working on your laptop or watching TV for hours in the evening. 

So whatever you do, estimate high. 

How Much Do RV Solar Panels Cost?

How much your RV solar panel system will cost depends on what you expect from your solar system. Setting up your RV with solar power is not a cheap project. 

On the bright side, there are great solar panels for RV that are available at any price point. 

Weekend RVers — Solar System Around $1,000

If you mainly use your RV over the weekend, you most certainly don’t need a solar system that can power a house. 

In that case, I recommend buying a solar system that will allow you to use the sun to charge phones, turn on the lights, and power a few outlets. 

If you’re not confident about using your RV's original wiring, you can pair your solar panels with a solar generator that already has multiple outlets for both 110V and 12V power. 

Solar generators already have a battery and inverter inside, so you only need to plug in the appropriate solar panels for RV.

Here are a few good combos:

Combo 1: The Bluetti Combo

Combo 2: The Jackery Combo

Combo 3: The Renogy Combo

Cost Of Solar Panels: A Walkthrough Guide

Hardcore RVers

If you like to spend several weeks traveling in your RV, I recommend you build a more capable RV solar system. 

Higher-end components are better built which leads to fewer maintenance issues. Manufacturers often offer RV solar panel kits that contain everything you need to build a full-fledged solar system for your RV. 

For example, the Renogy 800W 12V/24V Monocrystalline Solar Premium Kit costs $1,399.99  and includes eight 100-watt solar panels and a Rover 60A MPPT Charge Controller. 

But then you also need an inverter like this Renogy 1000W 12V Pure Sine Wave Inverter for $254.99.

And you need a deep cycle discharge battery. If you want to make the most out of those 3.4 or 4 hours that the sun is directly above, you’ll need at least a 2,000Wh battery. For example, this Renogy 12V 200Ah Lithium Iron Phosphate Battery costs $1,129.

How to Install Solar Panels on Your RV

Now let’s take a look at how to set up RV solar panels in the simplest possible way.

For starters, a solar system for RV has a few basic components:

• Solar panels for RV
• Charge controller 
• Solar battery 
• Battery monitor with a shunt
• Fuses and breakers  

And that’s it.  

But how do you hook up solar panels to RV batteries? 

You can’t charge the RV battery with solar panels directly. First, you need to hook solar panels to a charge controller and put a battery monitor in between the controller and the RV battery.  

It might sound complicated but it isn’t. 

Let’s begin with the RV solar panel installation.

Step 1: How to Mount Solar Panels on Your RV Roof

Depending on the kit you bought, you’ll either have to use Z-brackets or screws or silicone adhesive.

If you’re going with screws, mount the brackets and set your panel where you want it, and mark the holes for drilling. 

Now, this part is super important. You’ll be drilling through your RV roof so you don’t want any water to leak inside.

I used a Dicor Roof Sealant . Just apply some sealant over the markings so that when the screw goes in it pulls into that membrane and makes a watertight seal. 

If you're gluing the panels or using the tape make sure the adhesive makes a complete seal around the edges as you don’t want any moisture or dust to accumulate under your flexible solar panels.  

Step 2: How to Connect the Panels

If the wires you got in the solar panel kit are too short, you can use an extra IP65-rated junction box. 

From there, lead the wires into a circuit breaker . I prefer circuit breakers to fuses because I can disconnect the panels from the rest of the system with a flick of a switch. 

Step 3: How to Connect the Battery

Now, remember, you don’t want to hook your panels to the charge controller until you’ve hooked up the battery. 

Connecting the battery is quite simple. You’ll need a fuse in between there, so from the positive side of the charge controller go to the fuse and form there to the positive side of the battery. 

And on the negative side, first, lead a wire from the battery monitor shunt to the charge controller and then from the battery monitor to the negative side of the battery. 

Once you hook up the charge controller to the battery, it’s going to power up the display. From there you can finish hooking up the solar panels to the charge controller and turn on that little breaker. 

And that’s pretty much it. Now you can see what’s coming from solar panels into your battery. 

Rigid vs. Flexible Solar Panels: Which One Is Best for RVs?

Both rigid and flexible solar panels have the same job but they are built for different applications. 

Rigid Solar Panels

Usually have a metal frame and are encased in sturdy glass. This makes them much heavier, but also much more durable.

In the past, rigid solar panels were considered more efficient than their flexible counterparts. However in recent years, technology has advanced, so now they’re an equal match. 

However, two things haven’t changed:

• The rigid solar panels will take up less square footage than flexible panels.
• Rigid solar panels are usually less expensive .

Finally, rigid solar panels have a less tendency to overheat. Flexible panels sit directly on the RV roof so there’s nowhere for the heat to escape. Rigid solar panels have raised mounts that allow airflow all around them.

On the downside, the mounts produce more drag on the road, which translates to more fuel spent. 

So to sum up:

• More durable
• More efficient (in general)
• Less expensive
• Better cooling

Flexible Solar Panels 

Flexible solar panels are much thinner and built like laminate materials so they are bendable to an extent. This makes them perfect for curved or streamlined surfaces like boat hulls, RV roofs, etc. 

Since they are glued or screwed down to the RV roof they don't create any drag while on the road.

Flexible panels also weigh much less, which makes them perfect for RV and marine use. No one wants to put more weight than they already haul around. 

These perks combined make flexible solar panels for RV much easier to install on your rig. In some cases, you won’t need any tools but a tube of silicone adhesive or EternaBond tape. 

Flexible solar panels are also more portable. Removing and storing rigid solar panels is much harder. I’ve never heard of anyone in my RV community doing that. 

On the other hand, you can easily remove flexible panels from your RV roof to slide them into any bay for storage. 

So what do we have so far?

• Lightweight
• Fits any surface
• Easier to mount
• More portable
• More expensive
• More tendency to overheat

Verdict: Rigid vs. Flexible Solar Panels

If you ask me, solar panels for RV have to be either flexible or portable. Rigid solar panels are not just 70% heavier, but also require more complicated mounts, not to mention the additional drag on the road.

Can you run an RV on solar power?

Yes, you can run an RV on solar power. If you need to power just basic RV systems, you can start with solar systems and a battery bank. However, if you want to power the appliances you’d use in your home, you need an inverter to allow you to use a 110-volt system.

What is the hardest part of boondocking in your RV?

The hardest part about boondocking in my RV is water conservation and power conservation. Solar panels can help with the latter.

Can you run an RV air conditioner with solar power?

Yes, you can run RV air conditioners with solar power. But keep in mind that Ac units suck up a lot of power so you’ll need lots of solar panels and a large battery bank.

How many solar panels do I need to run 50 amps in my RV?

You need two 100-watt solar panels to run 50 amps a day in your RV.

Can off-grid solar systems work 24 hours every day?

Yes, off-grid solar systems are designed to work day and night 24/7.

Which is better for the money: RV solar panels or generators?

A generator is always cheaper upfront, but then you have to stop to refuel it, plus you get constant noise and the smell of diesel. RV solar panels are more expensive upfront, but once you clear the bill they keep giving as the power source is 100% free. In addition, you’ll rarely have to do anything about them, while the generators need regular maintenance.

Are RV Solar Panels Worth It?

RV solar panels are definitely worth the investment. 

Some of you will choose an inexpensive RV solar “starter pack” with a simple charge controller and a lead acid battery. 

Enough for charging a few devices between shore hookups.

Or you may want full independence from the grid and splurge on 8x100W flexible solar panels + pure sine inverter and LiFePO4 battery with 3,500+ discharge cycles. 

Others will go for maximum flexibility and rig up portable solar panels for RV and use a solar generator unit that is both an inverter and a battery in one. 

Let’s be honest — in any case, the upfront price is higher than what you’d pay for the fuel generator. 

But once you’re past the price point, everything is pure gain —  both for you and the environment. 

So, let me ask you this:

What price are you willing to pay to ditch the nasty exhaust fumes and harness the clean and free energy of the sun?

RV Solar Panels: A Must-Read Guide (With Expert Advice)

Traveling on the road from place to place in your RV can be quite satisfying, but for it to be enjoyable, you need to have power available on-demand. Coupling your energy demands with solar panels results in complete freedom from the grid while on the road.

When picking the different types of solar panels and other components for RV solar systems, it is important to have all the information beforehand. In this article, you will find a detailed explanation of the basics of RV solar panels, types of modules used for RVs, other important components, and a buying guide with advice from an expert on how to pick the best RV solar system for you.

Table of Contents

Basics: What are RV solar panels?

RVs are always on the road, constantly exposed to solar radiation. To take advantage of this, RV owners achieve energy independence by installing solar panels on their roofs or carrying portable solar panels for RVs.

RV solar panels can be fixed to the roof of the vehicle with fixed racking designed for them. Since the roof constantly receives solar radiation, RV solar panels can produce high amounts of electricity to power DC and AC loads while on the road or camping.

Having RV solar panels eliminates the need to stop at campgrounds to charge batteries with an external power outlet or the need to use external diesel generators. Solar panels only need exposure to the sun to generate power all day as long as no objects are shading the modules.

Benefits of RV solar panels

RV solar panels can be loyal allies on the road, delivering a great number of benefits. Let’s see some of them:

Simple to no installation

You can install and fix RV solar panels on the roof of your RV, but this is not always necessary. You can opt to have portable solar panels for RVs, which are placed around the vehicle facing the sun. Another option is to stick flexible solar panels for RV to the roof, which does not require drilling holes on the roof.

Portability

RV solar panels will go anywhere with you and will constantly generate power on the road, making them a loyal ally on your adventures. The only thing you need to be aware of is to never park in a shaded spot since your panels would not generate power or will do so at reduced performance.

Independence from the grid and power generators

Regular RVs stop at campgrounds to charge deep cycle batteries. Alternatively, they can use an external generator, but generators produce loud noises and require fuel constantly. RV solar panels are the best solution to these problems, since they only need sunlight to generate power and will work for 20 to 25 years.

What types of solar panels are used for RVs?

You now know the basics of RV solar panels and their major advantages, but can any solar panel do the work? Yes and no.

Some RVs have obstructions like ventilation shafts and other similar objects placed on the roof, limiting the available space for installing solar panels. Other RVs might not have flat roofs, making the installation more challenging.

To solve these problems, you can use one of the different types of solar panels fitted for RVs. These are the following:

Rigid or Traditional Solar Panels

There are two types of rigid solar panels for RVs: monocrystalline silicon and polycrystalline silicon . They are manufactured using the same source material but have different manufacturing processes and properties.

Monocrystalline Silicon

Monocrystalline silicon is the most powerful and efficient solar technology available for RVs. This technology can be used for homes and RVs, using solar cells manufactured from a single silicon crystal through a process known as the Czochralski process.

Monocrystalline silicon RV solar panels cost around $1.25/W  and the highest recorded efficiency for monocrystalline silicon is set at 25.4% . This technology is a better option if you are looking for a solar system yielding the highest possible power output.

The performance of these modules is affected by a temperature coefficient of nearly -0.38%/ºC . The installation usually requires drilling holes and using a fixing rack for the roof, but they also come in portable designs.

Polycrystalline Silicon

Polycrystalline silicon is created by melting various silicon crystals together, resulting in a solar cell with slightly higher impurities and lower efficiency, but at a much lower cost.

The highest recorded efficiency for polycrystalline silicon is set at 24.4%, while its cost is only $1.00/W , 10% less than monocrystalline silicon. These RV solar panels can be affected by temperature through a temperature coefficient of -0.39%/ºC .

Flexible Solar Panels

Thin-film amorphous silicon.

Amorphous silicon is a type of thin-film technology used since the early 70s. This technology achieved its highest recorded conversion efficiency at 14.0%, but its cost is also low at $0.69/W .

One major point in favor of amorphous silicon RV solar panels is their resistance to high temperatures. They are only affected by a temperature coefficient of -0.234%/ºC . This technology will provide an excellent ally when driving your RV in states with hot climates.

Monocrystalline silicon is not only used for traditional rigid solar panels. This technology was modified and improved in the last decade, to create flexible monocrystalline solar panels. This feature allows modules to be stuck to the roof, without having to drill holes to install racking.

Efficiency values for this type of technology are close to the values of traditional monocrystalline technologies, with efficiencies of 23% to 25%. These flexible solar panels are regularly used for RV rooftop installations and temporal installations at camping sites.  

What is the best type of solar panel for RVs?

Solar panels for RVs differ in aspects like price, conversion efficiency, temperature coefficient, and other factors. In this section we compare each of these:

COMPARING TYPES OF SOLAR PANELS FOR RVS

In the table above you can see major differences between types of solar panels for RVs. As you weigh your needs regarding efficiency, cost, and ease of installation, you might want to choose one or another technology.

Monocrystalline silicon comprises the RV solar panels with the highest power production. These are the best solar panels for RV when you are looking to demand high amounts of energy to live comfortably or want to charge your batteries faster. Polycrystalline silicon also produces a high amount of power while still saving some money. This technology has lower efficiency, but also a lower cost.

Both monocrystalline and polycrystalline silicon can be installed on RV roofs by using a fixing rack or be designed as portable solar panels for RVs. However, monocrystalline silicon technology also has the potential to be designed as flexible modules, adapting its shape to the roof of the RV.

Amorphous silicon is a very unique technology that allows manufacturing solar panels for RVs that adapt to curved roofs, featuring a much lower price per watt and performing better in high temperatures. The downside of this technology is its low efficiency and low power ratings. Amorphous silicon can be used to manufacture portable solar panels for RVs that can even be completely rollable, or also for manufacturing flexible solar panels for roof installations.

Other components in a solar power system on RVs

Solar panels are the major component of RV solar systems, but they are not the only ones. RV requires an off-grid solar system installation to power DC and AC loads.

RV solar systems require solar panels, a charge controller, a battery bank, and an inverter. Here you will learn what these components and their functions are:

Charge Controller

The solar charge controller regulates the DC voltage and current sent to the load and the batteries, setting the power output at the right level. This device uses a system known as Maximum Power Point Tracking (MPPT) to optimize the power output from the panels, finding the right voltage and amperage to extract as much power as possible from the system. The charge controller keeps the batteries charged without overcharging them and supplies power to the load as it is demanded.

Battery Bank

The battery bank is where solar energy gets stored for later usage, this is especially practical during harsh climates and nights. This component is comprised of one or several batteries connected to match the input voltage of the inverter and charge controller. Most battery banks are designed to operate at 12V, 24V, or 48V.

The solar inverter is responsible for converting the DC power coming from the charge controller into a modified or pure sine wave with a 120V voltage. This device provides your RV the capacity to power regular appliances like your computer, coffee maker, TV, and many others.

What to consider when choosing RV solar panels? (With expert advice)

Choosing the best solar panels for RV and other components for your vehicle can be challenging. To help you out, in this section we provide you with advice from an expert regarding the aspects to consider when choosing your RV solar panel system and other inputs.

Solar system size: Truly consider your energy needs

RVs do not require as much power as residential solar systems, especially since there are rarely any power-hungry devices like in a house. When spending the day at your RV, you might want to watch TV for a few hours (150W per hour or W/h), turn on your satellite internet (25W/h) for working or surfing the web on your laptop (100W/h), make coffee (1,000W/h), or use other low power consumption tasks.

All of these devices have relatively low power consumption, except for the coffee maker which consumes 1,000W per hour but only operates for 5-10 minutes. Considering and analyzing your power demand habits will help you estimate how much power you need, allowing you to invest in the right size for RV solar panels.

The previous equation can help you to estimate the ideal size for a PV system for your RV. The equation requires you to consider your daily energy requirements, expected Peak Sun Hours (PSH)  or effective hours of power generation at maximum capacity in the location where you will be camping, and a derating factor associated with PV losses. For properly estimating your energy consumption, you can use the widget for reference to obtain the power demand, you just need to figure out the amount of time that you intend to use these appliances.

What is the expected cost of RV solar panels?

RVs can have regular solar systems installed, but they usually go better with RV solar panel kits, which might cost as low as $100 or as high as $3,000, depending on what the kit includes. RV solar panel kits generally include RV solar panels, a charge controller, and wiring accessories,  but some kits can also include a power inverter and batteries, for a premium price of course.

The most simple 100W kit might cost around $100, but a 100W kit with a flexible solar panel might go up to $250. The price increases more and more, depending on the number and quality of the products included in the kit.

What is the best way to mount solar panels on RV roofs?

While portable solar panels do not require to be mounted on a roof since they can be installed on the ground of a camping site, this is not the case for other types of solar panels. To take real advantage of traditional and flexible solar panels for RV, the smart choice is to mount them on the roof of the vehicle. There are different types of mounting systems:

• Fixed mounting : Fixed mounting solar panels is the most straightforward installation method for rigid or traditional solar panels. This type of mounting requires you to drill holes on the rooftop of your RV and install the mounting brackets to fix the solar panel in place, on a flat position on top of the mounting system.
• Flexible mounting : Flexible solar panels adapt to the shape of your RV, making them easier to install on any type of RV roof. To install these types of solar panels, you usually have to use VHB tapes or EternaBond tape to set the panels in position. You might also have to drill a hole in your roof to send the cables into the RV, but this installation only requires one hole.  
• Tilt mounting : Instead of fixing solar panels on a flat position, you could install them with a tilt angle kit. This is a mounting system that includes a tilting platform, allowing you to tilt solar panels in the direction of the sun, depending on your camping location. This type of mounting system makes your RV solar panels absorb more solar radiation and yield a higher power output, especially during the fall or winter season.

Battery size: Amps per hour translate to autonomy

Batteries are an important component of your RV solar system. You might not require much power during the day when you are camping, but you will surely need it at night.

The best way to understand the capacity of batteries is by translating their amp-hour (Ah) capacity into watt-hours, by multiplying amp-hour by the voltage. For instance, a 100Ah battery operating at 24V can store 2,400Wh, more than enough to watch TV for a few hours, turn on your satellite internet, and your computer, and make some coffee during the day.

You should size your solar panel system with enough reserves to fully charge the batteries at least throughout the day. Increasing the days of autonomy (amount of days that you can live off-grid with a single full charge of the battery bank) will also require you to increase the  PV system size. Using the equation shown earlier in this section will help you size correctly your PV system to achieve this objective.

Choosing your charge controller

The charge controller regulates the variable power output of your RV solar panels, making it extremely important for your RV solar system. When choosing a particular charge controller for your RV, the main aspect to consider is matching the voltage input of the charge controller to the voltage output of the string of solar panels. Additionally , you should pick a charge controller that can handle an amperage higher than the total current output of the string of solar panels at your RV.

What is the best type of solar panel for you?

After learning all the benefits of different types of solar panels for RVs, you should now weigh the price, power rating, and efficiency, and consider available space on the roof of your RV against the dimensions of the solar panel. This will help you pick the best solar panels for RV and the ideal configuration for your system.

Top brands selling RV solar panels

Several brands have made a name for themselves by selling high-quality solar panels for RVs and RV solar panel kits. When looking for the best solar panels for RV, we recommend considering the options manufactured by these companies.

Share this experience

Do you want to install RV solar panels on your camper or RV and don't know where to start? From RV solar systems to inverters, and understanding what kind of solar panels are best for an RV, there’s a lot to consider when purchasing solar panels for your rig.

So why get RV solar panels installed? RV solar panels are a great way to power your RV when you’re looking to break away from electric hookup sites and try dry camping or boondocking . When you have RV solar panels and a solar system set up in your RV or camper, you'll be able to power all or some of your RV’s electrical needs like lights, appliances, and even your RV air conditioner.

Whatever size RV you have, before you purchase your RV solar panels, there are a few things you need to know.

RV Solar Panel Systems: Which Is Right For Me?

You have two options to consider when choosing solar panels for your RV or camper

1) Portable RV Solar Panel System

A portable RV solar panel system is the easiest to set up and use. These systems typically plug into a dedicated solar plug on your RV and include one or more 100-watt solar panels that can be attached to your roof with Velcro straps. Other portable solar panels come in a suitcase. You connect the panels via a cord and place them in an area around your RV that gets the most sun.

The portable RV solar panel system is a great choice for RVers who don’t need a lot of power. Maybe you want to use your lights, charge your devices (i.e. phones, computers), and top off your trailer batteries. This option can also be the lowest overall cost to entry, but note you will probably pay more per watt for the convenience of portability.

2) Permanent RV Solar Panel System

Installing permanent RV solar panels is more expensive up front, but this option is the most efficient. You'll get the best bang for your buck per solar watt, can maximize any unused roof space for panels, the panels will be constantly collecting sunlight (i.e. while driving), and the panels don't require setup once you’re parked.

Permanent RV solar panel systems are typically installed by an RV dealer or professional companies that specialize in RV solar panel installation. These systems are designed for those who are trying to maximize solar power not just to charge devices, but also to operate appliances like refrigerators, microwaves, coffee makers, and even air conditioners.

How Many Solar Panels Do I Need To Run My RV?

First, you need to determine your RV's power needs. RV solar panels are rated in watts, and you'll need to know the wattage (or watt hours) of all the devices you want to run on solar power — think your refrigerator, microwave, phones, TV, etc. For anything that uses electricity in your RV, you need to calculate watt use.

Calculating Watt Use

Locate the amps (or watts) on your devices to determine their usage. You need to convert everything to watts, so if a device only has amps, multiply it by the volts to get watts.

Example: A 120-volt rice cooker that draws 3 amps converts to 360 watts (120 x 3).

Once you know the watts per device used, determine how long you use it daily and multiply it by that “use rate” to get its daily watt usage or watt-hours.

Example: Using the above rice cooker for 30 minutes or 0.5 hours consumes 180 watt-hours (360 watts x 0.5).

Calculating How Many Solar Panels You Need

Once you determine your watt use, you can calculate the number of RV solar panels and how many watts of solar you need.

Most people think that a 100-watt solar panel produces 800 to 1,000 watts of power per day (8 to 10 hours of daylight). Unfortunately, that’s not the case. A conservative rule of thumb is that per 100-watt solar panel, you'll collect about 350 watts per day due to things like weather, optimum sun angle/exposure, and panel efficiencies.

Example: You have one phone at 5 watts to charge for an hour, you use a rice cooker that uses 360 watts for 30 minutes and you use a blow dryer that uses 1,500 watts for 6 minutes.

Phone: 5 (watts) x 1 (hour) = 5 watts

Rice cooker: 360 (watts) x 0.5 (hours) = 180 watts

Blow dryer: 1,500 (watts) x 0.1 (hours) = 150 watts

Total: 5 (watts) x 180 (watts) x 150 (watts) = 355 watts per day

Given this example, a 100-watt solar panel would be sufficient enough to generate enough power to charge your battery and run your devices each day. (Consult with the company installing your panels to determine the panel amount you need.)

What Else Do I Need For My RV Solar Panels?

You'll need more than just solar panels for your RV. There are a few more pieces to pick up, such as:

• Battery bank
• Charge controller

Battery Bank

Batteries store the electricity produced by the solar panel so that your RV can still be powered when there’s no sunlight available (i.e. at night or during bad weather). Technically, solar panels don’t power devices, the solar panels charge the battery and the batteries are what supply the power.

Most batteries are either 24 volts or 12 volts and rated in amps (or Ah). Ideally, you want a battery that has enough capacity to power all your devices and appliances for a couple of days. That way if you have a day of no or low sunlight, you still have some juice to power your devices and appliances.

RELATED: Boondock Basics: The Only Gear Guide You’ll Ever Need  

To find out how much battery you need (amps), calculate your watts and divide by volts.

An inverter charger converts DC power (produced by solar panels) into AC power that can be used by your RV's electrical system. It also can take AC power and convert it to DC power to charge your batteries.

To determine how large of an inverter you need, take the total watts you’ll use at any given time and multiply that number by 1.25.

Charge Controller

Lastly, you’ll need a charge controller. The main purpose of a charge controller is to create a one-way street for energy. The charge controller takes the energy generated from your solar panels and channels it to your battery bank.

The charge controller also monitors and stops potential issues like overcharging or discharge, which can ultimately damage your battery.

Are RV Solar Panels Worth It?

While the answer might be different for each person, there is time and money involved when deciding to add a solar panel system to your RV or camper.

Installing solar panels on your RV is ideal for those who:

• Are looking to get a little more off-grid when RVing; installing solar panels allows your RV to power up, instead of being connected to campground electric hookups/power.
• Are looking for a more sustainable solution to sourcing energy.
• Prefer the quiet collection of solar power over the hum of a gas-powered generator.

With research, time, and investment you can open up the possibilities of where you can go RVing.

RVs have batteries within them that are able to power lights and small appliances, but they won’t last very long. If you want to be able to use things like your microwave and TV, then you’re going to need an external power source. That’s where RV solar panels come in . 

RV solar panels work like a regular home solar system - the solar panels convert sunlight into electricity. Except instead of the solar panels powering your home, they charge your RV batteries. 

You can also get additional batteries that the solar panels can charge, so you have even more electricity available to you when you’re camping. 

An RV solar panel system consists of 4 main components: 

Solar panels to convert sunlight into electricity

A charge controller to prevent your battery from overcharging

An inverter to convert the DC solar electricity into usable AC power

A battery to store the electricity

Do you really need RV solar panels?

While RV solar panels are great, they aren’t necessary. In fact, most RV campers probably don’t need solar panels - if you spend most of your time camping on campgrounds with power hookups, then RV solar panels probably aren’t right for you. 

But, for all of the boondockers out there, RV solar panels are a great, cost-effective investment. Boondocking is when you camp off-grid, outside the amenities of campgrounds, including electricity. In this case, RV solar panels can come in handy. They allow you to keep your batteries charged, and you can charge additional batteries for backup power, as well. 

Also, because the solar panels slowly charge your batteries, they can end up prolonging your RV battery life. Plus, unlike conventional generators that you may use to help power your RV, you don’t have to worry about buying propane for every trip. Once you invest in RV solar panels, there are almost no additional operating costs unless equipment needs to be replaced.

How much do RV solar panels cost?

How much you spend on solar panels for your RV depends on what you need from your solar system. If you use a lot of electricity, you’ll need to purchase more equipment, which will raise the overall price of your RV solar system. 

You can find RV solar panel kits for as little as $100 or upwards of $1,000. It really depends on your energy needs. When you’re just starting out, you can get an RV solar panel starter kit between $200 and $500. 

Kits in this range will usually include a charge controller, solar cables, and one or two solar panels, which is a great jumping-off point when you’re first getting into solar. But, you’ll probably still need a generator to supplement your usage. Once you gauge how the solar panels are working for you, you may need to buy more panels. 

What to consider when buying RV solar panels

There are a few key things to keep in mind when looking to buy solar panels for your RVs. 

Your power consumption

In order to find what solar panels are going to work best for your RV, you need to figure out how much power you consume when you’re camping . Based on that, you’ll be able to determine how many solar panels and any additional batteries you might need. 

Most RV campers use about 20 kilowatt hours (kWh) of electricity a day. The more appliances you have, the higher your electricity usage will be, and thus the more solar panels you will need. 

In most cases, however, two or three solar panels will usually produce enough energy to run most of your small appliances. If you want to run large appliances like a refrigerator or an air conditioner, you’ll need a generator or additional panels and batteries. 

You might not know exactly how much power your RV uses, and that’s okay. You can always purchase a basic RV solar kit and do a test run to see how it meets your needs. Then, you can expand the system to include more panels or batteries if need be. 

System setup

When you get solar panels for your RV, you can use them one of two ways: 

Manually set up portable solar panels

Mount the panels on your roof

For most boondockers, manual setup is relatively easy. You simply lay out your solar panels, connect them to your battery, and face them towards the sun. Then, simply move the panels in the direction of the sun every couple of hours to increase solar production. Keep in mind, however, it is something you have to set up and put away each time you go to a site. 

Roof-mounted RV solar panels are also an option if you don’t want to set up portable solar panels. However, you won’t be able to park your RV in the shade, as the roof will need to be exposed to sunlight. You also won’t be able to turn the panels towards the sun to get a little extra juice. Roof-mounted systems could be slightly more expensive, but their convenience can be beneficial to full-time boondockers. 

Type of solar panels

There are three main types of solar panels : Monocrystalline, polycrystalline, and amorphous panels. Monocrystalline are the most efficient and the most expensive. If you are limited on space, then monocrystalline panels are definitely the panels for you. Polycrystalline panels are slightly less efficient than monocrystalline panels, so they are a little bit cheaper.

Amorphous solar panels are flexible, thin-film solar panels. Although they are the cheapest option, they are the least efficient. This means you would need more of them to produce even close to what the mono or polycrystalline panels produce.  Plus, they must be installed directly onto your RV’s roof using glue, which can cause damage and make them difficult to remove. 

Learn more : Types of solar panels: which one is the best choice?

In our opinion, going with a monocrystalline or polycrystalline panel is the best choice for switching your RV to solar power . However, if you have an RV with a curved roof, like an Airstream, then flexible amorphous solar panels might be the best way for you to have a roof-mounted solar system. 

If you are using solar panels with your RV, you’ll probably want to get some additional battery banks to store your solar energy. Most RVers choose 12v batteries. You can get lead acid batteries or lithium-ion batteries for your RV, but each comes with its own set of pros and cons. 

Lead acid batteries are the most commonly used batteries for RV campers. They’re cheap and durable, which is what makes them so popular. However, they usually need to be replaced after five years, and depending on the type of lead acid battery you choose, it might require regular maintenance. 

Lithium-ion batteries are substantially more expensive than lead acid. However, they last much longer, store more energy, and are more efficient. For people who are boondocking full-time, lithium-ion batteries are worth the extra money. 

But, if you are only using the batteries for a few trips a year, you can get away with a couple of lead-acid batteries. 

Keep your camping trip clean with RV solar panels

As you can tell, there is a lot you need to consider before buying RV solar panels. With limited space and limited power output, it can be difficult to figure out exactly what you need from an RV solar system. 

If  you’re a frequent boondocker, it’s worth it to at least pair your generator with a set of solar panels. The RV solar panel kits we listed are sure to be a great starting point for transitioning to solar energy. 

But why stop at your RV? You can save on energy costs and help the environment by powering your whole home with a residential solar panel system. Our solar panel calculator can tell you how much solar can save you on your specific home! I am running a few minutes late; my previous meeting is running over.

Key takeaways

You can keep your lights on even when you’re off the grid by installing RV solar panels.

RV solar panel systems are made up of solar panels, a charge controller, a battery, and an inverter.

If you normally camp at designated campgrounds, RV solar panels might not be for you. But if you are boondocking off-grid, solar panels can really help improve your trip.

RV solar panels vary in cost, but most starter kits cost between $200 and $500.

When buying RV solar panels you need to consider your power consumption, your system setup, the type of solar panels, and the type of batteries you want to use.

Solar Panel Buying Guide for RVs and Travel Trailers: What You Need to Know

Whether you're living that mobile, off-grid lifestyle or just want power for the occasional camping trip, solar panels on your RV can keep you powered up and comfortable.

Interested in outfitting your camper with solar panels? Start here.

In recent years, more people seem to be living and working from the road than ever before, whether it's in a large RV, travel trailer or camper van. To maximize the freedom of such a lifestyle, having a reliable source of electricity is imperative, and few sources are better than the massive ball of fire that rises in the east each morning. 

Adding a solar energy system to your home office on wheels has become markedly easier and cheaper, but there are still plenty of choices, questions and considerations that aren't always so straightforward. We've put together this quick guide with the help of a pair of seasoned pros to determine if solar is right for your ride. 

What are RV solar panels?

RV solar panels work just like residential and commercial solar panels except on a smaller, more transportable scale. Once they're installed on your RV, motor home or camper, solar panels collect sunlight and convert it into usable electricity for your vehicle. In turn, you can use this electricity to power the appliances, lights and sockets in your RV.

Can solar panels save you money?

Interested in understanding the impact solar can have on your home? Enter some basic information below, and we’ll instantly provide a free estimate of your energy savings.

There are a number of reasons to add solar panels to an RV, travel trailer or camper. The most obvious is that traveling around often means spending the night in places where there's no easy access to the electrical grid. The most adventurous among us today manage to live and work full time from the road, making solar all but a requirement. 

"We knew we wanted to go solar to save money, be off grid and live the lifestyle we wanted and live more sustainably," Shari Galiardi told CNET via Zoom from an off-grid campground in British Columbia. 

Galiardi and her partner, Dave Hutchison, have lived and worked full-time from a restored 1957 camper trailer since 2012 with the help of a 300-watt solar system. They told me that while the lifestyle is certainly different from that of the average person, they don't feel as though they're sacrificing very much.

The couple rarely camp places that have power hook-ups, preferring to be off-grid. Hutchison estimated that once in a year they'll plug into an electric outlet at a campsite. 

"Usually, that's because it's all that's available," he said.

Can RVs use residential solar panels?

It is possible to mount regular rectangular rooftop solar panels on an RV, trailer or van. This author has done so twice. However, it isn't the most aerodynamic arrangement.

Considering Solar Panels?

Galiardi and Hutchison use flexible, lightweight panels that can contour to a vehicle's roof and also add less weight to the top of a trailer. There are a number of products that can work with RVs, including portable panels that can be set up on the ground at your destination.

How many RV solar panels do you need? 

Unlike residential and commercial solar systems, which are designed to power an entire home or business, RV solar systems typically deliver a more modest output. This usually isn't an issue, since you don't use as many lights and appliances in your RV as you would in a brick-and-mortar property.

So how many solar panels will you need for an RV? It depends on a few factors, including your energy consumption habits, the efficiency of the panels and the amount of sunshine your home receives each day.

The energy demand of a camper van like this is likely to be met with fewer solar panels than a typical home.

Determining the ideal size and wattage of a mobile solar system works the same way it does in a stationary residential setting. Calculate how much power you'll need during peak usage scenarios and plan your panels accordingly. 

If anything, it should be easier to figure out your requirements, since you'll likely have fewer appliances to consider in an RV. However, an important consideration is the unpredictability of the sunlight your RV will receive while traveling. Unlike a house, your RV's location and orientation will always be changing, so you may want to design your system with this in mind. 

Installing an RV solar panel system

Initially, Galiardi and Hutchison had a friend with experience in the solar industry help them build a small, rudimentary solar system. After a few years, they upgraded their system and even earned a sponsorship deal with a solar panel company.

There are three main  kinds of solar panels for RVs: monocrystalline, polycrystalline and amorphous. 

• Monocrystalline panels are the most efficient of the three, so they'll generate the most energy in the least amount of time. 
• Polycrystalline panels are slightly less efficient, but they're a durable and reliable option.
• Amorphous panels  aren't as efficient as their counterparts, but the thin and bendable construction makes them easy to install and a lighter-weight option.

In addition to solar panels, you'll need several other components to complete your RV solar system, including the following: 

• Solar inverter , which converts the solar energy from DC to AC power.
• Charge controller , which protects the storage system from overcharging.
• Solar battery , which stores the generated energy.

Portable solar panels present another option for RVers.

Because it can be difficult to keep batteries topped up solely by using solar, a backup source of power is also a good idea. Many travelers use some sort of gas or propane generator. Galiardi and Hutchison are equipped to charge up their lithium batteries using their truck while driving. 

"Self heating batteries are fantastic if you're camping in any sort of colder climates," Galiardi says. 

This is typically more of a need with lithium batteries, which can be more efficient, lower maintenance and longer-lasting than flooded lead-acid batteries, but are also more sensitive to cold. 

Finally, a cord to plug into the grid to recharge when it's available is also a must for most. 

RV solar panel maintenance

There's little maintenance to worry about with solar panels. If you're traveling in very dusty or windy conditions, you may need to wipe off or clean your panels to ensure they're working at maximum efficiency.

Traveling may also add a bit more wear to a panel's connectors. Standard solar panel connections are quite weatherproof, but it's worth inspecting your system periodically for signs of deterioration, loose connections or rust. 

It's not recommended to service these parts on your own without the guidance of an experienced electrician. Remember that a panel can be generating energy any time the sun is up, even when it's cloudy, so always treat any connections as live circuits. 

Here Are 23 Ways to Save On Your Electric Bills Right Now

Cost and rebates

The overall cost of your system will depend on factors including the type of panels you choose and how much electricity you need to generate. If you need lots of power, you'll need to buy more equipment, driving up the price.

Galiardi and Hutchison said their 300-watt system with batteries, inverter and other components cost about $3,000, while larger systems for bigger RVs can easily run more than twice as much. 

The good news, according to Galiardi, is that incentives, including the 30% federal tax credit for home solar systems, can apply. 

"It includes second homes. And RVs and boats and off-grid cabins are in that second home realm," Galiardi said.

Are RV solar panels right for you?

It's difficult to argue with the benefits of solar energy, but RV solar panels might not be right for everyone. If you live in your RV and often take it off-grid (where there are no campground hookups), then solar can be a convenient and eco-friendly alternative to gas-powered generators.

Portable and flexible solar panels better suited to RVs may be more expensive than standard rooftop residential panels, but they're still remarkably cheap compared with past eras. 

There's little reason not to boost your freedom by adding a solar system to your rig if you can afford it, though if you use your RV infrequently, it may not be worth the investment.

Hutchison noted that there might be no need for panels if you only ever park your RV at developed campgrounds with provided power.

However, he added it's worthwhile to consider a system with panels and batteries, even "if you plan to spend even one night off-grid between those sites."

While looking for the finest RV solar kit can be difficult if you’re unfamiliar with the lingo, we’ve done the legwork for you and compiled everything you need to know regarding solar panels for RV trailers so you can choose the best kit for your power requirements and budget.

To begin, you’ll discover the fundamentals of RV solar panels, including how they operate, a comparison of common types, camping perks, and critical purchasing criteria. Following that, there will be a list of the most renowned companies on the market, followed by a full evaluation of the best solar panels for RV, with each product being supported with key features as well as advantages and disadvantages so that comparisons can be made easily. Just at the conclusion of the review, you’ll find answers to frequently asked concerns from other campers.

How Do RV Solar Panels Work?

A solar panel, or perhaps an arrangement of them, catches the sunlight, turns its energy directly into electrical energy, and sends it to the charge controller, which then feeds it to your batteries at just the right current for storage.

Photovoltaics (PV) is the process of transforming light (photons) into electricity (voltage). Photovoltaic cells are the smallest units that make up solar panels.

Put bluntly, a solar panel generates energy by enabling light particles, or photons, to knock electrons loose from atoms.

The productivity of this process is growing as photovoltaic technology progresses. Most panels have a conversion efficiency of 10-15%, which means that 10-15% of the sunlight collected may be turned into useful energy for your setup. The most advanced technologies utilized in high-end applications can achieve efficiencies of up to 21%.

The electricity generated by the solar panels will be stored in batteries. Solar power is so erratic that it’s impossible to use it effectively right off the panels.

There are two ways to access the energy stored in your batteries. Devices designed to work on 12 volt DC electricity have direct access. Nevertheless, many pieces of equipment, including those in a home, requires 110 volt AC power.

The inverter is required to convert the current in the batteries from DC to AC. This tool enables you to use your AC equipment.

Types Of RV Solar Panels

Solar panels for RVs come in a variety of shapes and sizes, but they may be divided into three categories: polycrystalline, monocrystalline, and thin-film. To discover the perfect solar panels for RVs on the market, you must first understand the characteristics of the various panel types in order to select the most appropriate kit for your camping requirements.

Silicon is used to make all solar cells. The effectiveness and price of the cell, and hence the panel, are determined by its purity and structure.

Polycrystalline Solar Panels

Poly-crystalline solar panels have a distinct blue appearance. The cells have a rectangular shape.

Polycrystalline solar panels are made by melting raw silicon and have low pricing, making them popular among budget-conscious RVers. Models of this type are well-suited for large applications due to their inexpensive cost.

In terms of drawbacks, polycrystalline solar panels offer middling efficiency given their size. Because the crystalline structure is not as pure as monocrystalline, they are significantly less efficient.

Furthermore, numerous polycrystalline solar cell products do not manage heat well, which indicates that devices may fail prematurely if exposed to excessive temperatures.

Monocrystalline Solar Panels

Mono-crystalline solar panels have such a wafer-like appearance. Monocrystalline solar panels, which use the truest form of silicon obtainable, have higher efficiency than some other types of panels. To minimize the cost and enhance productivity of a panel, the silicon is cut on four sides before being sliced into wafers.

Furthermore, because these products can withstand high temperatures, they would be excellent selections for a variety of trips. In partial shading or low light conditions, monocrystalline solar cells often outperform polycrystalline solar cells.

Monocrystalline solar panels are more expensive than polycrystalline solar panels because the silicon purification process is much more expensive.

CIGS Solar Panels

Copper Indium Gallium Selenide is a sort of Thin Film solar panel that generates a lot of energy compared to other Thin Film forms, with such efficacy of around 10% to 12%.

An additional advantage is that it contains less cadmium, a hazardous element commonly used in panel manufacturing. Solar panels made of CIGS are perfect for compact as well as foldable solar arrays.

Thin-Film Solar Panels

Thin-film is a recent technology in which silicon is put on a substrate surface onto lower manufacturing costs, needing less than 1% of the silicon required by a comparable polycrystalline or monocrystalline panel with the same dimension. This type of solar panel is available at an affordable price due to its ease of manufacture.

Thin-film solar panels, which can be bent, are unrivalled in terms of ability to adapt: they may be used in a variety of situations. The decreased cost of thin-film makes it appealing for larger installations when space is a constraint.

Nonetheless, there is a cost associated with efficiency. Thin-film solar panels have lower efficiency, typically 7-13 percent, compared to those with higher 15-20 percent of crystalline panels, hence they are generally limited in power-hungry motorhomes. Thin-film solar cells, on the other hand, will undoubtedly come in handy for on-the-go power.

RV Solar Panel Kits

Since the energy generated by solar panels includes peaks and valleys, it’s critical to regulate the power reaching the batteries to maintain adequate charging, safeguard both the solar panels as well as the batteries, plus maximize throughput.

A charge controller, which provides this task and can manage many panels getting connected to a single unit, is included in most solar panel kits. An inverter, which transforms the current in your batteries from DC to AC to power numerous equipment that needs 110 volt AC power, such as those in your residence, would be included in the package.

A controller recognizes the charging condition of your batteries to obtain the best possible charging with the given current from the source of power, as well as several other charging-related tasks, regardless if your power supply is solar, generator, or shore energy.

The best RV solar panels currently should provide a controller that uses Pulse Width Modulation, a type of smart charging (PWM). Both speed and width of the pulses are controlled automatically by this form of controller, allowing exhausted batteries to be charged rapidly. And for the final piece, the controller will change functions to fully charge the battery and afterwards hold the full current charge.

Frequently Asked Questions (FAQs)

What type of solar panel is best for rv.

Solar panels for RVs come in three main varieties, each with its own price range, effectiveness, and flexibility. The best RV solar panels are determined by your energy requirements, budget, setup, and weather conditions.

Monocrystalline solar panels have the best efficiency because they use the purest form of silicon available. They can also withstand high temperatures and generally outperform in partially shaded or low-light environments. The only disadvantage is their expensive price.

Polycrystalline solar panels are less expensive than monocrystalline solar panels, making them ideal for large-scale applications. However, because the crystalline structure isn’t quite as clear as the monocrystalline variety, they have middling size efficiencies. Furthermore, they aren’t known for their ability to withstand high temperatures.

Due to new technology that lowers production costs, thin-film solar panels are now available at the most affordable prices, rendering them appealing for larger installations. Thin-film solar panels are unrivaled in terms of versatility, allowing them to be used in a wide range of applications. Thin-film solar panels, on the other hand, have an efficiency of roughly 7-13 per cent, compared to 15-20 per cent for crystalline panels.

How much solar power does my RV need?

A solar panel with a power rating of roughly 100 watts is capable of generating approximately 6 amps every peak sun hour in general, which translates to about 30 amp-hours each day.

In fact, how much energy you require is determined by your power consumption, so it would be important to estimate your daily average intake and also the maximum energy demand on a particular day when you are using multiple devices at once. On an ordinary day, you’ll probably need at least two solar panels with a total capacity of roughly 100 watts each to operate your RV.

When it comes to the finest RV solar panels and kits, charging your vehicle’s battery bank with a clean and plentiful power source would be a breeze. The finest solar panels for RV batteries are genuinely helpful for you, particularly if you enjoy dry camping and boondocking.

The greatest RV solar system kits can indeed help you avoid running out of energy while you’re on the road. This could give you lots of sense of security and allow you to experience the conveniences and amenities of your homes while you are gone from that too.

RV Solar Components

Solar vs. generator: which is better, installing solar panels on your rv.

• Frequently Asked Questions

It's increasingly common to see solar panels on the roofs of recreational vehicles (RVs). While solar panels can't replace an internal combustion engine and turn your RV into an all-electric vehicle, they can allow you to run your lights and appliances cleanly rather than relying on a fossil-fueled generator.

Solar panels also give you the freedom to camp off-grid and in places that don't allow generators, rather than having to find a spot in a crowded campground with an available hook-up. And of course, with solar panels, you can reduce your carbon footprint.

Here, we discuss RV solar components and whether they are worth investing in for your next RV trip.

RV solar is not as simple as attaching solar panels to the roof and plugging in appliances. Here are the main components in an RV solar system.

Solar Panels

Panels can be flexible, portable, or rigid. Lightweight flexible panels are better suited when an RV roof is molded rather than flat, while portable panels can be placed anywhere on or off the vehicle, so they can capture sunlight even if the RV is parked in the shade. Rigid panels are much heavier, but they are also more durable and efficient. Panels may generate 150 watts in flexible and portable panels and up to 250 to 300 watts in rigid panels.

Most RVs have two batteries. A 12-volt lead-acid/AGM starting battery is used to start the engine, while a 12-volt RV "house" battery bank is used to run the DC-powered appliances, such as fans, lights, and water systems.

An AC/DC inverter can provide 120-volt power from a "shore power" hookup at an RV campground to power air conditioners, microwaves, and other energy-intensive appliances. In more modern RVs, older lead-acid RV battery banks have been replaced by lithium iron phosphate batteries charged by solar panels and the RV's engine alternator via DC/DC chargers. Together, these provide much more rapid charging and much longer-life battery banks, especially suited for off-grid use.

Some RV owners upgrade to lithium-ion batteries, which are lighter, more efficient, maintenance-free, can hold more energy, and have a longer lifetime. The downside is they cost significantly more.

Solar Charge Controller

A solar charge controller protects your battery by regulating the flow of electricity from solar panels to the battery. The controller matches the voltage output of the solar panels to the voltage capabilities of the battery or batteries.

Many RVs already have inverters that convert DC power from your 12-volt battery into 120-volt AC power used by your lights and other electrical equipment. More expensive inverters can produce more reliable and consistent power needed to run sensitive equipment like electronics or medical equipment.

Transfer Switch

A transfer switch allows you to switch the source of your power from the battery to shore power when parked in a campground, or to turn off a propane source when you are driving.

It's no surprise that solar panels are more environmentally friendly than fossil-fuel generators. Here are some other factors to consider:

• Energy : Solar panels require adequate sun to charge your batteries, while generators require adequate fossil fuels.
• Space : A generator and its fuel take up a significant amount of interior storage space. Solar panels are limited by the amount of roof space.
• Flammability : Fuels for generators (usually diesel, gasoline, or propane) are flammable. Some states prohibit the use of propane generators while driving.
• Maintenance : Generators need regular maintenance and can leave sulfate residues in batteries. With no moving parts, solar panels need little maintenance other than dust and debris removal.
• Power Speed : Generators provide instant power. Solar power is slower.
• Costs : Solar panels usually cost more to install than a generator, but once installed, the sunshine is free and infinitely renewable.
• Noise : Running a generator at night in a crowded campground will not win you any friends. Absolutely quiet solar panels, however, do not generate anything at night.
• Emissions : Generators emit greenhouse gases, carbon monoxide, and particulate matter, while solar panels are emissions-free. The manufacture of solar panels is not carbon-free, but neither is the manufacture of generators or the fossil fuels that run them.

Installing solar panels on an RV is no more complicated than installing them on the roof of a home.

Treehugger Tip

If you are uncomfortable or inexperienced in working with electrical systems, hire a professional, such as a professional RV converting company.

When you're ready to purchase and prepare for installation, remember to:

• Calculate how many panels you will need . Identify the power requirements of your appliances and how many hours per day you use them.
• Consider what equipment your RV already has . A number of RVs for sale on the market already come solar-equipped or solar-ready. For safety and efficiency, be sure that your RV has heavy-gauge wiring adequate to supply the full amount of power from your panels to your batteries.
• Buy everything at once . Each component of your RV solar system needs to be compatible with each other. RV solar panel kits are more expensive than buying each component separately, but their components are already compatible.

Installing an RV solar system consists of upfront costs that can be expensive. But these costs may save you money in electricity and fuel costs, as well as camping fees. Solar panels will also reduce your greenhouse gas emissions. If you want to go completely emissions-free, consider a car-camping road-trip in an electric vehicle.

Depending on the amount of sunshine you get and the amount of energy you use, a single 100-watt solar panel is likely to be able to keep a 12-volt DC battery charged. It is likely you'll want multiple higher-wattage panels and perhaps multiple batteries to give you more power for a longer period of time.

Depends on your usage. The larger upfront cost of solar panels, compared to a generator, pays itself off if you frequently rely on solar power off-grid. However, if you only park your RV in campgrounds with shore power, it's probably not worth your money and effort to invest in solar panels.

If your RV is not solar-ready, you may need more than a minimal 100-watt solar panel kit with mounting brackets and a solar charge controller, which can cost as little as $150. With a lithium-ion battery and multiple panels on your roof, the cost can be a few thousand dollars.

How Do RV Solar Panels Work?

As you shop for the best solar panels for your RV, it may be helpful to know how solar panels actually work .

Generally speaking, a solar power system for an RV works like a typical residential solar system. The panels draw energy from the sun and an inverter turns it into an electrical current, which is then distributed throughout your RV’s electrical system. 

Solar energy can be converted and used in real-time, but a battery can make your solar harnessing worthwhile. A battery may be used to store any excess power that’s generated by the solar cells so that you can still power your system on low-light days or at night.

Do You Need Solar Panels for an RV or Campervan?

When it comes to RV camping and van-living, there are typically two major “camps,” if you will — the campground electrical hook-up-ers and the off-grid adventurers. Naturally, both can benefit from using solar power, but the need looks a bit different for each. 

If your ideal RV trip is to a campground with an electrical outlet, then you don’t necessarily need solar energy for your camper. But if you would rather take an eco-friendly approach to camp, then an RV solar panel kit is the way to go. Plus, you won’t be out of luck if you get to your favorite campsite only to find that all the electrical hookups are taken.

Whereas those who frequent the campgrounds often have access to electricity, our boondocking folks take a more rugged approach by living off the land or whatever they can fit in their van. That means limited or no access to electrical hookups. 

Our off-grid RVers or van-lifers will likely get more out of a solar panel system because it could be used as their only energy source. Instead of relying solely on batteries and propane to power their equipment, off-grid folks can use solar energy.

What to Consider When Buying Solar Panels for Your RV

Solar panel type.

There are three basic types of solar panels for RVs: monocrystalline, polycrystalline and thin-film solar panels.

Monocrystalline and polycrystalline solar panels are both made from silicon. The difference is that monocrystalline panels are made with a single, unbroken silicon crystal, while polycrystalline panels are pieced together from silicon fragments. Monocrystalline panels tend to be a bit more efficient, but also a bit more expensive.

Thin-film panels can be made from a number of different materials. They’re the least expensive option, but also the least efficient. Many RVers prefer this type of panel because they tend to be more lightweight, flexible, and portable, which makes thin-film solar panels well-suited for RV use.

Portability

Portability is a sought-after feature for RVers who don’t want to mount their panels on their RV roof. These panels can easily be moved around to face direct sunlight so that you can harness more energy. Portable solar panels have other advantages, such as:

• Easy to install and set up
• Can be moved around
• Often less expensive than mounted panels
• You can still harness sunlight if you park in the shade
• Avoid the use of noisy generators

The downside to portable solar panels is that you have to manually set them up for every use and shift them around as the sun moves across the sky. This inconvenience is why some RVers and van-lifers opt for mounted solar panels.

Expected Energy Consumption

Before buying solar panels for your RV, you’ll first want to figure out how many panels you’ll need . The number of panels generally depends on two factors:  the amount of power you consume and your energy goals.

On average, RV campers use about 20 kilowatt-hours of electricity each day . This number is for your basic setup of appliances, but if you’re powering more heavy-duty appliances, you’ll probably need more panels. 

The number of panels you need also depends on your energy goals. If you want to rely solely on solar energy, for example, you will need enough panels to offset your use. But if your goal is to use partial solar energy, then you’ll need fewer panels.

If you don’t know how much energy you use when camping, it doesn’t take a lot of effort to find out. One of the best ways to determine how much solar energy you need is to buy a basic solar setup and see how far that power goes. If you need more than the starter kit to offset your wattage, you can easily add panels and batteries.

Battery banks are an important component of any RV solar power system. Most RVs will only need a 12V battery, but some may opt for higher voltage depending on what needs to be powered.

You’ll also need to choose between lead-acid batteries and lithium-ion batteries. While lead-acid batteries are a common choice, they typically need to be replaced and maintained more frequently than lithium-ion ones. 

If you camp most of the year, the more efficient, longer-lasting lithium-ion batteries will be worth the investment. But as always, it all depends on your unique solar energy goals and how much power you need for your appliances.

Final Thoughts: Is an RV Solar Power System Right for You?

After learning more about mobile solar systems, it’s time to decide: Are solar panels worth it for your RV camper?

Solar can be a great option if you consistently camp at sites that have electric hook-ups and you wish to reduce your environmental footprint. They can be an even wiser investment if you frequently camp where you don’t have access to the power grid. 

Make sure you do your due diligence so that you can find the best solar panels for your RV, your budget, and your camping lifestyle.

5 Best RV Solar Panels and How to Pick the Right Ones

By: Author The Drivin' & Vibin' Team

Posted on April 20, 2024

Many RVers long for the freedom of exploring entirely off-grid, and the most eco-friendly way to boondock is to use solar panels to energize their RV batteries.

Sure, RVing offers independence, but many seek to be completely untethered from utility hookups and campground amenities. They long to wander through seldom-seen landscapes and visit destinations far away from population centers.

However, not all solar setups are equal. So, we’ll break down RV solar panels for you in this short guide.

Let’s jump in!

Picking the Best Solar Panels for Your RV

There are a few factors to consider when picking solar panels for your RV. Here are five key factors to keep in mind.

To Mount or Not to Mount?

You may want to start with a small amount of wattage when you begin your foray into the world of solar power. For instance, you may only want a suitcase solar panel to charge your small electronics or trickle-charge your RV battery.

On the other hand, many RVers graduate to larger solar systems to power their entire vehicle. This may include placing portable panels on the ground at a campsite or fixing them on the roof of their trailer or motorhome. There are obvious benefits for both types of panels.

The flexibility of portable RV solar panels makes them the perfect partner when your access to the sun’s rays changes. Move the panels to a new position or tilt them to follow the sun.

However, the quality that makes them attractive can also catch a thief’s attention. So, if you plan to be away from your campsite for any length of time, finding a way to secure your solar panels will be challenging.

Mounted panels are certainly more secure, requiring less setup (after installation), but they’re usually more expensive because of their permanency. They can collect energy while you travel and generate power whenever your recreational vehicle is in the sun. And no setup time is needed, whether on the road or at a campsite.

Solar Panel Type: Rigid or Flexible

If you choose to mount your solar panels, your next decision will include what type of panels to use. Rigid RV solar panels include solar cells created on a solid frame. These frames then attach to your motorhome or trailer on a rack a few inches above the roof. This allows air to flow under the panels and does not transfer heat directly into the coach.

Often rigid panels can tilt to follow the sun throughout the day, making them the most efficient solar panels. Some RVers even opt to set rigid solar panels on the ground, where they can tilt or move them out of shady campsites and into the sun.

Flexible panels are great for uneven surfaces. They can attach with either screws or Eternabond tape if you don’t wish to drill holes in your roof. However, they generate some heat into the vehicle because of their placement directly on your RV’s roof.

In addition, when it’s time to replace them, you may have a bit of a mess taking the old panel off if you used glue or tape for attachment. Flexible solar panels are generally less expensive than rigid ones, but they don’t usually last as long. 

Portability and Storage 

If you’ve decided to go with portable solar panels, make sure your rig has enough storage space to pack them away when not in use and while traveling. Smaller setups can be the size of a big suitcase, but larger, more rigid panels may require more space.

RV solar panels of all types come in various wattages from 10 to 400 watts per panel. You may find single panels of 150 watts each, as well as 320-watt ones. Most can be mixed and matched with your system to offer the power you need collectively.

Before creating your system, you should complete a “solar” inventory to find the amount of wattage required to run your rig’s electrical appliances for the desired period of time each day. Then build a solar system that will deliver that energy to your batteries on sunny days.

Pro Tip: Don’t make these RV Solar Mistakes when installing your solar setup!

Factors to Consider When Choosing a Solar Kit for Your RV

When it comes to choosing a solar kit for your RV, there are several important factors to consider. These factors will ensure that you select a kit that meets your power requirements, fits within your budget, and integrates seamlessly with your existing electrical system. Let’s take a closer look at some of these key factors.

Power Requirements and Energy Consumption

First and foremost, you need to assess the power requirements and energy consumption of your RV. This will help you determine how many solar panels you will need and what size they should be. Consider the appliances and devices you use regularly while camping, such as lights, fans, refrigerators, and more. By understanding your power needs, you can choose a solar kit that provides sufficient energy to keep everything running smoothly.

Solar Arrays will produce a varying amount of energy depending on the time of year and where the system is. As a general rule of thumb, in Springfield Oregon, 100W of solar will net about 300Wh of energy in an average solar day. Using a calculator, like PVwatts , is a good way to refine this rule of thumb to your individual use case. 

As an example, a 3.8 Cu ft 12V DC fridge may need about 6A or so to run the compressor, which is about 75W or so. If we assume the compressor is on half the time (0.5 duty cycle) then our total Wh demand in a day is 450Wh (75W * 24 hr * 0.5). This means we would want at least 150W of solar (450Wh / 300Wh) to offset this 3.8 cu ft DC fridge, using the general rule of thumb. If we wanted to explore using this system in the winter, it may be better to do a thorough analysis with a tool like PVWatts. 

Available Roof Space

Another factor to consider is the available roof space for solar panel installation. RVs come in different shapes and sizes, so it’s important to measure the roof area where the panels will be mounted. This will help you determine the maximum size and number of panels that can be installed. Additionally, consider the orientation of your RV when parked. Aim to position the panels where shading from vents or A/C units is minimized.

Battery Capacity and Storage Requirements

Battery capacity and storage requirements are also crucial considerations. Solar panels convert sunlight into electricity, which is stored in batteries for later use. Assess your battery capacity and determine whether you need to upgrade to a larger battery bank to accommodate the additional energy generated by the solar panels. Additionally, consider the type of battery you have or plan to use, as different solar kits may be compatible with specific battery chemistries. As a general rule of thumb, 100W of solar panels in Springfield, Oregon will bank 25Ah in an average solar day.

Budget and Cost Considerations

Of course, budget and cost considerations play a significant role in the decision-making process. Solar kits vary in price depending on their size, quality, and additional features. Determine your budget and look for kits that offer the best value for your money. Keep in mind that investing in a high-quality solar kit may result in long-term savings on fuel costs and campground fees.

Compatibility with Existing RV Electrical Systems

Last but not least, consider the compatibility of the solar kit with your existing RV electrical systems. Check if the kit includes all the necessary components. AM Solar sells kits for all applications including, complete kits with panels, cores for existing pre-wire, and empty shells with no pre-wire. 

By carefully evaluating these factors, you can select a solar kit that is tailored to your specific RV needs. Remember to consider your power requirements, available roof space, battery capacity, budget, and compatibility with your existing electrical systems. Doing so will ensure that you make an informed decision and enjoy the benefits of solar power while on the road.

Installing Solar Kits on RVs: A Step-by-Step Guide

Installing solar kits on RVs can provide a reliable source of electricity while on the road. Whether you’re a seasoned RV enthusiast or new to solar power, here are some guidelines to help you with the installation process.

• Determine your energy needs: Start by calculating the total wattage and hours of operation of the appliances and devices you’ll be using in your RV. This will help you determine the total Watt-Hour need of your use case, and subsequently, the size and number of solar panels you’ll need.
• Choose the right solar kit: Consider your available roof space and power requirements when selecting a solar kit for your RV. Remember, as a general rule of thumb 100W will net 300Wh a day. AM Solar offers a variety of solar panel kits for RVs, such as the kits listed above. Choose a kit that suits your needs.
• Mount the solar panels: Clean the roof surface where the mounts will be installed with 91% isopropyl alcohol. Set the panel with mounts on the roof and position it while the mounts are semi-loose.  This will let everything settle into a natural tension-free position. Go around and tighten each Bolt gradually, being careful to keep the L-Foot in the same position. Lift the panel and peel the tape cover off of each mounting foot. Place the sticky panel back on the roof in the same exact position. Check that each foot is flat against the roof, and loosen knobs to make adjustments if necessary. Apply the sealant by completely burying the mount foot. We also have a video here , that details installing mounts onto panels without predrilled holes. And a video here , detailing the above rooftop instructions.
• Determine your interior wire route and install the combiner box (if not using a prewire): Choosing where you want your interior wire run to go is a mixture of aesthetic preference and electrical efficiency. Ideally, distance is minimized which means the shortest run from the roof to the battery bank. In practice, in or shop, we are usually wiring through void spaces between panels, or in closets where the loomed wire will not be an eye sore. Once you have determined your route, you will want to drill from the inside out to the roof. This will allow you to control the layers of the roof you drill through and minimize the amount of unnecessary holes in the roof. Once the spot looks good from below and above, use a hole saw for the wire gauge being used in the kit to expand that hole. You will then pull the wire up though the roof, leaving a small length poking up out of the roof. You are now ready to install the combiner box. Peel the tape off the back of the box, and using the sealant provided mount the box to the roof making sure the wire you pulled through is going through the main roof side exit of the box. Caulk the outside edge of the box to keep water away from the tape. Strip back the wire and connect it to the buss bars inside the combiner box, red on red and black on black. We have a video here , detailing the process. 
• Connect the charge controller to the battery bank: Install the on/off switch either near the MPPT, which will be installed close to the battery bank, or close to where the wire enters the rig on the inside. Run the remaining wire to the battery bank/MPPT area, make your connections, and install the output breaker.
• Configure the MPPT and commission the system: Using our programming guides for your given battery, program the controller for optimal settings to ensure efficient charging of the battery bank. Turn everything on, and open your VictronConnect app to see how the system is performing to spec.

Maintaining and Maximizing Performance:

• Clean your solar panels occasionally: Use soft water and a terry cloth to keep the panels clean. Avoid abrasive materials or harsh chemicals that may remove the anti-reflective coating or damage the seal of the solar panel. 
• Check wiring connections: Regularly inspect the wiring connections to ensure they are secure and free of corrosion. Loose or corroded connections can decrease the efficiency of your solar kit.
• Monitor performance: Use a battery monitor or VictronConnect App to track the performance of your solar panels. This will help you identify any issues or inefficiencies in your system.
• Troubleshooting: If you encounter any problems with your solar kit, refer to the resources provided on our website. We offer articles and guides on RV solar systems, including installation and troubleshooting.

Installing Solar Panels on an RV

Before installing solar panels on an RV, you should first know how and where you want to mount your panels. Drilling holes into your RV’s roof is critical, so endeavor to get it right on the first try.

Take note that all RV roofs aren’t the same. Also, the solar panel arrangement that worked for others may not work for you. However, you may not have to worry about hole drilling if you’re using a flexible solar panel .

Still, planning for the best positions to place your panels for durability and efficiency is necessary.

Before purchasing your solar panels, ensure to take detailed measurements of your RV roof. Take note of all AC units, vents, and any other items on your roof that could obstruct your RV solar panel installation. For best results, draw a diagram of your entire roof with the measurements and positioning of the panels.

What You Need for Installing Solar Panels on RV

Once you’ve decided on the perfect positions for your RV solar panel mounting, the next step is to get the right supplies and tools to properly secure the panels to the RV roof.

Here’s a list of some of the tools you need:

• Cordless Drill
• Mounting Z Brackets (required: 1 set for each panel)
• Dicor Self-Leveling Lap Sealant

How to Install Solar Panels on RV in 7 Easy Step -By-Step Guide

Installing solar panels on an RV will be seamless if you follow these seven easy steps.

Step 1: Create a Position for the Solar Panels on your RV Roof

Before proceeding with your RV solar panel installation, create a better position for the solar panels on your roof. Double-check if the panels properly fit in the position before drilling holes into your roof.

Keep in mind that the process will differ based on the type of solar panel you have. For instance, rigid panels must be attached to the RV roof using screws. Flexible panels are mounted with adhesive, although they can also be mounted with screws.

It’s worth noting that the material used in building the upper layer of your roof will determine the type of adhesive needed. As a result, many RV solar panel kits don’t come with adhesive. Rather, they only come with the mounting hardware.

Ensure the panels are mounted in a position where air conditioning and vents won’t shade them.

Step 2: Connect Mounting Brackets to Each Solar Panel and Set them Aside

The next step is to attach mounting brackets to each solar panel. As earlier mentioned, the RV solar panel mounting process may differ depending on the panel type.

However, you must install rigid panels with screws by drilling into your roof. They can be fixed tilt-mounted or affixed flat to your RV roof.

Step 3: Identify the Spots Where you Need to Drill Holes in your RV Roof

Identifying the spots where you need to drill holes on your RV roof applies when installing rigid solar panels with a fixed mount. In such a case, you must bolt the brackets tightly based on your panel’s positioning.

Then, apply sealant underneath the brackets to keep the seal airtight and prevent potential roof leakages. However, you don’t have to drill holes if the panels have flexible designs. Such designs can be mounted with adhesive attached directly to the roof surface.

In addition, removable types, like EcoFlow Portable Solar Panels, have a foldable design and portable carry case. They’re easy to set up and require no installation.

Step 4: Drill a Pilot Hole in Your RV Roof and Screw Your Mounting Brackets

Position your solar panels and mark where you need to drill holes. Then, drill small pilot holes into your RV roof where your brackets will be screwed down. Ensure the holes will hit studs in your RV so your panels are secure.

Then, fill the holes with a small quantity of the Dicor sealant to help ensure that everything remains watertight. Although all RVs are different, the studs are usually visible with a 2-3-inch-wide gray line that goes width-wise off the roof.

Step 5: Using Butyl Tape, Line the Bottom Edges of Each Panel

Line the bottom edges of each solar panel with butyl tape and arrange the panels in place. Covering the panels with butyl tape helps add security to your panels and prevents them from flying off.

Step 6: Use the Screws from the Mounting Kit to Connect the Panels to the Roof

Attach the solar panels to your RV roof using the screws from the mounting kit. Ensure that the panels are properly placed in their mapped-out positions.

Step 7: Apply a Good Amount of Dicor Sealant

Apply a generous amount of Dicor sealant around and on top of the mounting brackets to seal everything off. Make sure to apply the adhesive directly to the butt joint in the roof surface and around the mounting brackets to seal them off from sun rays.

Attaching Solar Panels to RV Roof Without Drilling

After deciding the type of solar panel you’d love to use, it’s necessary to consider mounting it. Depending on your chosen type, there are different methods of attaching solar panels to an RV roof without drilling.

Portable RV Solar Panels

Portable RV solar panels are great at harnessing the energy of the sun. They’re great alternatives to traditional installations for RVers willing to undertake a DIY project. These panels require a simple setup and are ready to use.

The two most common portable RV solar panels are foldable and suitcase solar panels. Foldable solar panels have more than two panels and fold up in an accordion style. To set up this solar panel, all you need to do is attach the clamps to the battery terminals, and you’re good to go.

On the other hand, the suitcase solar panels come in a folding set of two 50-watt panels. An adjustable kickstand allows it to stand upright or at the desired angle. To set up this panel, attach the alligator clamps to your RV battery’s negative and positive terminals and connect the panels to the attached solar charge controller.

RV Solar Panel Corner Brackets

One of the most effective methods for mounting solar panels to your RV roof without drilling is using corner brackets. These brackets are made of ABS plastic. They’re usually attached to the four corners of the solar panels and adhered to the RV roof using silicone glue.

Corner brackets are only for aluminum-framed, rigid solar panels. They don’t work with flexible panels. To install these brackets, you’ll need to place them on all spots on the panel, mark holes, and drill them through each marked area.

Then, fasten the brackets to the solar panel using the provided bolts and nuts. Apply silicone adhesive, preferably Sikaflex 252 , to the underside of the brackets and place it in the desired roof’s position.

VHB tape is a lightweight, affordable option for mounting solar panels without drilling. It’s an extremely strong double-sided tape that can be applied quickly and easily to solar panels.

Despite its ease of use, VHB isn’t strong enough to adhere rigid solar panels to an RV roof. Hence, it is strictly used on flexible solar panels only. To apply VHB tape, remove the plastic layer from one side of the tape and stick it to the solar panel’s bottom edges.

Then, remove the plastic layer from the other side of the tape and firmly press the solar panel onto the desired roof location. When applying this tape, ensure that the area is dust-free and isn’t too cold outside.

RV Solar Panel Wiring Diagram

After sizing your RV system and the panels, the bulk of work starts! Below are different RV solar panel wiring diagrams. Each diagram illustrates how to connect the solar panels, battery bank, and charge controller.

100W RV Solar wiring diagram

A 100-watt solar system powers small items like a roof vent , LED lights, and a cell phone. It’s more suitable for camper vans but is great at providing supplementary energy on the go.

However, the amount of power a 100-watt solar panel can provide depends on factors like the weather, location, type of charge controller you install, and time of year. A 100-watt solar panel provides about 30-32 amp hours per day.

200W RV Solar wiring diagram

A 200W RV solar panel system is enough to power small 12V appliances, like a sink pump, a cell phone signal booster, and a laptop. It’s less likely to power a portable refrigerator full-time. So, it’s a good setup for supplementary power.

This RV solar panel is relatively small and has an easy setup. Unless you’re considering wild camping in your RV, this panel gives you reliable access to shore power.

Besides, it can run a small, energy-efficient fridge, making it a good option for small campers. However, if your ideal solar system is larger than 2200 watts, build the system with scalability in mind.

300W RV Solar wiring diagram

A 300-watt solar system can support the energy demands of a couple or even a small family in a medium-sized motorhome. Careful use and monitoring can take up to a year without needing other energy sources like hookups or driving.

This panel provides approximately 90 to 96 amp hours daily. Since you may be unable to recharge the batteries daily, consider having an alternative (as a contingency) to avoid cycling the batteries more than necessary.

Overall, 300-watt panel systems reserve a day or two, depending on your usage.

400W RV Solar wiring diagram

A 400-watt solar panel system gives you a couple of days in reserve, depending on your usage, without other sources of recharging. It’s enough to run your roof vent during the day and night to stop condensation.

In addition, it can recharge small devices on a USB, like tablets, kindles, and phones.

How much 400 watts of solar panels can power depends on the time of year, the location, the type of charge controller, and the weather. However, they’re capable of providing 120 to 128 amps daily.

Large RV solar wiring diagrams (400W or more)

800 watts of solar power is enough for even the largest RVs and campervans. Large RV solar panels provide about 200 to 256 amp hours daily.

They’re enough to run a large fridge, an inverter for a TV, a coffee maker, and charge laptops. If you plan to live in a camper during the winter , the 800W is a full-service luxury.

With large RV solar panel systems, there’s no need for driving or shore power. Although you’ll always need to monitor the battery levels and usage with a solar system this size, you’ll comfortably have enough energy to meet the needs of four people.

Materials Needed for Wiring Your Solar Panel into Your RV

When wiring your solar panel, there are certain materials you must have in place. Some are batteries, mounting brackets, connectors, solar panels, cables, and an inverter.

All the necessary materials must be available, whether you’re wiring your solar panels in parallel or series. While there are numerous inverters, 300W, 600W, 1000W, and 1500W are the most common for solar panels between 100W and over 400W.

The most commonly used alternator chargers are B2B chargers and battery isolators. Wires and fuses are additional parts for all solar systems. In all, before choosing a solar panel system for your RV, make sure to research all its specifications.

How to Wire the Solar Panels into Your RV

After mounting solar panels on your RV roof, the next procedure is to start wiring them. Below are the actual steps for wiring the solar panels into your RV:

• Mount the RV solar panels to the roof using the parallel or series method.
• Attach the charge controller to the RV’s interior near the battery bank.
• Run wires from the solar panels to the charge controller with a circuit breaker or fuse.
• Connect the charge controller to the battery bank 
• Then, connect the solar panels.
• Caulk and seal any holes or exposures created during the installation process. If using an inverter, it should be mounted very close to the battery bank.

Parallel Wiring vs. Series vs. Parallel Series

In series wiring connections, the negative cable of one panel goes to the positive of the second one, the negative of the second goes to the positive of the third, and so on. Then, the two unused cables from the first and last panels go into the charge controller.

Wiring in series means the panel’s amperage remains unchanged, but their voltages are combined. The negative and positive cables often go into a combiner box for parallel wiring connections. One thick positive cable and a negative cable go into the charge controller.

Sometimes, the MC4 branch connectors are used instead of a combiner box. Parallel wiring means the panels’ voltage remains, but their amperages are combined. The series-parallel connection is usually used with numerous panels.

It’s a combination of the two other wiring methods, which allows you to adjust the amps and voltage of your solar array to the properties of your charge controller. For instance, you can create two strings of panels with high voltage but wire them in parallel to combine their amperages.

Wiring your RV Solar Panels in Parallel

Wiring RV solar panels in parallel is when the positive and negative (+ and -) wires are grouped. This type of wiring allows each panel to operate on its own.

Solar panels wired in parallel require higher-gauge wiring because the amperage is the wire gauge’s limit.

Don’t wire your solar panels in parallel for units of over 500 watts because you’ll need to buy expensive, thick wires to make the connection efficient.

Wiring your RV Solar Panels in Series

The lowest-performing panel in series wiring connections sets a limit on the output. All other panels will be removed if one panel is in the shade.

Connecting your solar panels in series doubles the voltage going through the wires while leaving the amperage unchanged.

Use an efficient charge controller. Voltage is the reason why charge controllers have a limit. Hence, RV solar panels wired in series require a more expensive charge controller.

Wiring your RV Solar Panels in Series-Parallel

Wiring RV solar panels in series-parallel means that you have multiple series that you’re wiring in parallel. For example, if you have four solar panels, you could have two sets of two panels.

While one series might be wiped out due to a panel in the shade, the other can still perform at maximum capacity.

You double your voltage and amperage rather than quadruple for a four-panel array wired in series parallel. This allows you to limit the gauge of your wires and the size of your charge controller.

Final Words

The biggest determinants of a solar panel RV installation are your budget and power demands. Although you may consider hiring a professional to take care of the installation, it can also be a seamless DIY project. All you need to do is follow the steps in this article and rest assured of a perfect RV solar panel mounting and a better off-road experience.

If you’re using a flexible panel, you can use adhesive to fix the panels. Run the wiring through a conduit to a cable entry plate and connect it to a charge controller. The installation and wiring materials are affordable and easy to access.

Once your solar panel system is installed, maintain and inspect it regularly to ensure optimal performance. Neglecting routine maintenance can lead to reduced efficiency and potential issues.

Although an RV solar installation can cost about $500 to $2,000, the investment is worth it. So, get started with your RV solar panel installation already. Do you have any questions or suggestions on installing solar panels on an RV? Let us know your thoughts in the comment section!

FAQs on How to Install RV Solar Panel

How do rv solar panels work.

RV solar panels convert solar energy into direct current electricity (12V DC), which charges the RV’s batteries and stores the electricity. Passing the 12V DC through an inverter converts it into 120-Volt AC (alternating current), which powers 120-Volt gadgets like a coffee maker. In short, with solar panels, you can power almost anything.

How many solar panels does it take to power an RV?

Five solar panels are enough to power an RV if your total power consumption is 10,000 Wh. However, the number of panels largely depends on your power consumption needs and environmental conditions.

Can I connect the solar panel directly to the RV battery?

Yes, you can, but it’s not advisable. Connecting the solar panel directly to the RV battery can cause explosions and overheating. Instead, connect it to a charge controller. It’ll help guard the battery against overcharging and improve its lifespan.

How many batteries do I need for my RV solar system?

1 to 4 batteries are enough for your RV solar system. Generally, every 100 amp hours of battery storage capacity is enough for a 300-watt solar panel system. So, if you have two 12V or any combination of batteries that sum up to 200 amp hours, your solar panel output shouldn’t be less than 600 watts.

Do you need an inverter for RV solar panels?

Yes, you do. Residential solar panel setups run on DC, so your RV solar system needs an inverter to convert the DC to AC energy. If you’re using solar panels to power your RV, the energy they collect must first go through an inverter before you can use it.

INTRODUCING SŌL

Powered by the sun.

Travel is a time for more exploration. More fun. More memories.– but using solar energy to power your RV is even better. Our new solar packages, SŌL – Powered by the Sun, make it easier than ever to harness solar power for your next trip. With three options to choose from, you can have a solar package that supplements your typical energy use, or go for a higher tier that powers your RV when you camp off-grid.

INTRODUCTION TO SŌL

Why should i choose solar power.

Campers of all kinds can benefit from the unique qualities of solar energy. It’s particularly good for off-grid camping, allowing you to generate power wherever you park.

How does solar energy work?

Unlike generator power, your RV doesn’t run directly off of solar energy. Instead, the solar panels convert sunlight into direct current (DC) electricity, which is stored in onboard batteries. That means you’ll have energy banked to use overnight or on bad-weather days.

What are the tiers for Sol - Powered by the Sun?

Every current Cruiser RV comes SOL Prepped. That means you can add solar panels, batteries and an inverter on every one of our models. We’re currently rolling out new models with Tier 1 and Tier 2 solar packages, detailed below.

HAVE QUESTIONS?

View our solar options page to learn more about our offerings and find solar resources.

Privacy overview, energy savings.

Cut your energy costs by keeping batteries charged with free solar power.

Using freely available solar power can keep your batteries charged while lowering your energy costs. And the initial investment in solar panels, batteries, an inverter, etc., will more than pay for itself in the gas and electric it saves you over the coming years.

Low Maintenance

Once your solar package is installed, they require very little upkeep and work for years. Most of the labor of upgrading to solar power happens right upfront. Once you install your solar panels, batteries, inverter, and wiring, you’re good to go. Solar energy systems are so low maintenance, your biggest concern will be keeping the panels clean to absorb as much light as they can – which a good rain shower will take care of on its own.

Travel Flexibility

Solar expands your camping options by giving you greater freedom to go off-grid. Whether you want to camp in style, get way off the beaten path, or just have the flexibility to go where the wind takes you, solar power is an asset. It can help power all your appliances, while saving energy. It can allow you to camp off-grid for longer, using sun to meet your energy needs. Or it can give you the freedom to not make a plan, knowing you’ll have power wherever you go.

Quiet + Ecofriendly

You’re in the great outdoors to get away from man-made noise – and generators can be loud. But with solar energy, you can have a totally silent way of storing and using energy. Every element of solar power is noise-free, which means you can tune into the natural world in peace.

Reliable Power

Did you know that fewer than 1% of solar panels fail in any given year? That level of unmatched reliability is what makes solar power so popular with campers. There aren’t too many things in this world that you can depend on – but your power source on the road should be one of them.

Why Should I choose solar power?

Campers of all kinds can benefit from the unique qualities of solar energy. It’s particularly good for off-grid camping, allowing you to generate power wherever you park. That means fewer calculations about which appliances to run and for how long when you’re boondocking. Solar power is environmentally friendly and renewable, which not only cuts costs, but helps protect nature for future generations of campers.

Unlike a generator’s loud buzz, solar energy is totally noiseless. And all the work to access solar energy is upfront – once you have solar panels and an inverter installed, the system will work for years with nearly zero upkeep. A good rainstorm every now and then keeps the panels clean from dust and pollen, so your panels capture as much sunlight as possible. Finally, solar energy is flexible. Not only can it expand your camping options, but you can choose configurations that supplement your typical energy use with solar, or use it to replace other forms of energy entirely.

How Does Solar Energy Work?

Unlike generator power, your RV doesn’t run directly off of solar energy. Instead, the solar panels convert sunlight into direct current (DC) electricity, which is stored in  onboard batteries.  That means you’ll have energy banked to use overnight or on bad-weather days.

Then, an inverter installed in the RV converts DC electricity to alternating current (AC), which is the type of electricity used in residential homes. DC electricity powers elements of your RV like slideouts, lights, power awnings and fans. But household appliances typically use AC electricity, which means the inverter allows you to use solar energy to power things like your electrical outlets, microwave, washer and dryer, hair dryer, coffee maker and more.

Solar Powered RV: How To Run Your Camper Off Solar

O ne of the greatest things about RV travel is the ability to go off-grid and totally immerse yourself in nature. The thing is, you will eventually run out of battery power doing so. Many people turn to generators to solve this problem, but generators are noisy and are not even allowed in some areas. You certainly don’t want to be running one 24/7, either.

For this reason, we much prefer the idea of creating a solar powered RV for your boondocking adventures.

The only problem? Many people are intimidated by the idea of putting solar power on RV campers. This is understandable; putting solar power in RV trailers and motorhomes can be a huge, expensive, and technical process. Fortunately, there are ways to make solar powered RVs more accessible to the average joe.

In this article, we will teach you how to run your RV off solar, breaking the process down and simplifying things so you can tackle the project with confidence. 

Note: This is a very simplified version of an RV solar power system. There are many things you can do differently to make the system work best for you, but this will get you started.

How to Run Your RV Off Solar: What You Need

First, let’s talk about the RV solar supplies needed to get your off-grid electrical system up and running. Gather these items and you’ll be ready to jump into your solar project. 

Solar Panels

First, you will want to grab some solar panels. Many people put a lot of thought into figuring out how many panels to buy based on their electricity usage. Our advice? Skip the complicated math for now and simply get 2–4 panels, depending on what your budget can handle. It’s easy to add more panels down the line. 

We recommend this kit from Renogy , as it is incredibly easy to install and get wired into your system. 

Charge Controller

Another must-have piece of RV solar equipment is your solar charge controller. Without a charge controller, you can’t really connect your panels to your battery safely. The panels linked above come with a controller, but these components can be bought separately from one another if you prefer.

We recommend an MPPT charge controller over a PWM option because it will be a bit more efficient. However, either one will be fine as long as you get one that can handle the amperage put out by your solar panels. 

You’ll also need a bank of batteries in order to store the solar power your panels pull in. This may leave you wondering which is the best battery for RV solar.

In our opinion, the best battery for a camper is definitely a LiFePO4 (lithium-ion phosphate) battery. Fortunately, these are becoming more and more affordable as time goes on, and in our experience, even off-brand lithium battery options such as these work just fine. 

We like lithium batteries because they are 100% maintenance-free, relatively lightweight, and can be discharged completely without issues. They are also far safer to store in enclosed spaces where there’s little ventilation.

That said, if you need to cut costs somewhere, traditional flooded batteries should work fine, assuming you have the weight capacity and the ability to stay on top of battery maintenance, as well as a safely ventilated place to store them.

We also recommend investing in an inverter. As long as you connect your battery bank to your RV, you can use your solar power via your RV’s DC electrical system, which includes your fridge, lights, and vent fans. However, without an inverter, you will not be able to use anything on the AC side of things—meaning the air conditioner, microwave, and power outlets.

There are a couple of options here: You can choose to purchase a large inverter charger (see next paragraph) to take the place of your existing RV converter and wire the new inverter into your RV’s breaker box, or you can choose a smaller portable inverter that you will need to plug things into directly. There are also inverters that do not charge the batteries but can be hardwired into the RV’s system. 

We personally chose to install this inverter charger from Sungold , and it is very convenient when it works correctly, as it automatically switches between inverter mode and charger mode when we connect/disconnect shore power. Unfortunately, the inverter broke after only a month of use, meaning we couldn’t use the inverter or charge our batteries for a couple of months while we fought the warranty folks to fix our issue. Because of this, we kind of regretted this choice and don’t necessarily recommend this product.

On top of the troubles we had with our inverter charge, installing such an inverter is a bit more advanced. Therefore, for this article, we will be focusing on using a more basic inverter such as this one .

No matter what inverter you buy, make sure it is a pure sine wave inverter rather than a modified sine wave version. (If you buy a small inverter from, say, AutoZone, chances are it will be modified sine wave and of no use for this application.) You will also need to make sure your batteries can provide enough power to get the inverter running. Three 100 amp hour batteries are just enough to run our 3000-watt inverter.

Breakers and Wires

You will also need some breakers and wires. 

These include:

• Battery cables — Bigger is better, so we went with 4/0 gauge wiring for our bank of three 100-amp-hour batteries.
• DC circuit breaker — This goes between the solar panels and the charge controller. Choose the amperage accordingly. If you’re installing the two 100-amp-hour panel kit linked above, this 25-amp breaker will work.
• Manual reset inline fuse/circuit breaker — This goes between the charge controller and the battery. Choose amperage accordingly. If you’re installing the two 100 amp hour panel kit linked above, this 40 amp breaker will work.
• Wiring from the solar panel kit — You might need to add additional 10-gauge wire depending on the length of the runs.

Creating Your Solar Powered RV Setup

Now that you have all of the things you need, the next thing to do is actually install your solar power for RV living. We’ve tried to keep everything simple and provided easy-to-follow instructions below. 

Related Post: Pros and Cons of RV Living Full Time

Create Your Battery Bank

The first thing you will need to do is get your battery bank hooked up and ready to go. If possible, choose a place that is near the location of your factory-installed battery in order to make it easy to tie the new bank into the RV’s DC system. Connect the batteries together in parallel using the battery cables mentioned above.

This video will help you do that:

From there, you will just need to connect the battery bank to the RV’s electrical system using the same cables that were used to hook up the old batteries, using the positive post on one end of the bank and the negative post on the opposite end. If this is not possible due to the location of the battery bank, you will need connect the bank to the RV’s fuse panel, which is a bit more complicated. 

How to Mount Solar Panels to RV Roof

The next thing you’ll need to do to install solar power for an RV is learn how to mount solar panels to RV roof. 

Start by figuring out where you will mount the panels. Clean the area well. Attach the brackets included in the panel kit to the panels using the included screws. Place the panels on the roof—ideally with the brackets resting on top of frame studs—and create pilot holes using a drill. Move the one panel out of the way, put RV roof sealant in each pilot hole, replace the panel, screw the panel onto the roof, and cover the screw and the bottom of the bracket in sealant. You can completely coat the top of the bracket with sealant as well if you want more peace of mind.

Repeat this process with all other panels you install, then give the sealant a day or two to fully cure.

Connecting the Panels to the Charge Controller

Using the included cables, plug the panels into one another using the instructions in the video below. We recommend connecting them in parallel rather than series. 

Next, run your solar panel cables into the RV to the place where your charge controller will be mounted (Preferably near the battery bank). Many people will drill a hole in the roof, but we just ran the cable through a gap in our slide seal, using cord covers to keep everything tidy and in place. You could also go through an existing hole in the roof.

Connect wires to the DC breaker, add a wire of the same size to each side of the breaker output, and connect these wires to the charge controller using the instructions included in the kit. Be sure you screw them down tight, but be careful not to overtighten as this can irreparably damage the inserts.

Linking the Charge Controller to the Batteries

Run a 10-gauge wire from the positive output of the charge controller to the inline fuse/breaker and then to the battery bank, connecting the positive to the same positive terminal/post you used to connect to the DC system. Do the same on the negative side but without the breaker in the middle. 

Once this is done, your solar panels should be charging your batteries and you will officially have an RV with solar power. If you wish to be able to monitor your battery charge level, we recommend a battery monitor. We have this one from Renogy and it has served us well.

Adding an Inverter to the Mix

The last step in creating your solar powered camper? Your inverter. As mentioned above, an inverter is not entirely necessary, but it sure does make your solar RV power system more usable, and the GIANDEL product linked above is incredibly easy to hook up and use. 

All you have to do is connect the cables from the positive side of the inverter to the main positive post on your battery bank and do the same with the negative. 

From there, you can choose to plug anything you need to use directly into the inverter, or you can plug the entire RV into the inverter using a 20-amp adapter. Plugging the RV in will allow you to use your outlets and possibly your microwave (depending on the inverter chosen and your microwave’s wattage). If you have a soft starter installed on your RV air conditioner, you may also be able to use that (though it will drain your battery bank very quickly). Keep in mind, you won’t be able to run everything in the RV at once. 

If you prefer an inverter charger, you will need to learn how to hardwire it in. Many RVers seem to like the Victron inverter charger . 

There you have it, everything you need to know to create a very basic solar powered RV setup. If you’ve been dreaming of having RV solar, why not order the supplies you need and get started right away? You won’t regret it!
