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.

RV solar panels pros and cons

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.

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.
