What are RV solar panels and how do they work?

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: 

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.

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.
