Benefits of Solar Panels & Kits for RV
- Save some money. Minus the initial investment, using solar panels saves you a lot. The free power generated will pay for itself within months of use. Since most panels guarantee over 20 years of generating clean energy, you save a ton in energy costs in the long run.
- Save the planet. Whether global warming and energy conservation is an issue you care about or not, there's no denying the positive effects of using renewable energy. So even if you only want to use solar panels for the financial benefit, you can still take solace in the fact that you're doing your part to go green.
- Low maintenance. While other sources of energy can cost you a lot of money in upkeep, solar panels are amazingly low maintenance. The number of parts that can get worn or break is incredibly small, and the panels don't have moving parts, which also reduces any wear and tear that other power sources are prone to.
- Battery life. A lesser-known benefit of solar power is that it has positive effects on your RV’s battery. The added solar power requires less work from the battery, which can lead to a significantly longer battery life.
Types of Solar Panels & Kits for RV
These solar power panels for RVs are made from a single crystal, often a very thin layer of silicon. The panels have an array of smaller square solar cells laid out across its surface. This technology performs better than polycrystalline solar panels in low light conditions. However, due to the costly purification process, this type of panel is often more expensive.
Polycrystalline solar panels are made up of several smaller crystals in each cell. These panels have rectangular solar cells across its surface, and sometimes have a bluish hue to them. Overall, polycrystalline technology is less efficient than monocrystalline. However, it can also be considerably cheaper.
A newer solar technology comes as a thin film. The cells are still made of silicon, but they are much thinner and flexible. These solar cells come with an adhesive backing that almost works like a tape. Once again, the efficiency is lower than the others, but it is much more cost effective. This is what’s used in the best flexible solar panels for RVs.
Renogy got its start as a college project by students at Louisiana State University. Since then, thanks to support from the Louisiana Business and Technology Center, the business has become one of the fastest growing companies. It produces some of the most popular motorhome solar panel kits like its Foldable Solar Panel Kit and Flexible RV Solar Panel.

Solar charge controllers are what manage the amount of power that is stored from sitting in the sun. These are essential for preventing overcharging of a battery during the day and reducing any loss of power overnight. They are currently made in MPPT and the newer PWM technologies. While PWM is better for power management, it is significantly more expensive.
If your energy usage increases or you just want to expand the items you have running on solar power, a useful feature is an expandability. Some solar panel kits allow you to add additional solar panels to generate up to 400 or 800 watts, depending on your camper trailer solar setup.
Having a solar panel is no good if you can't set it up. It's important to pay attention to what is necessary for installation and what parts come included. Some helpful features are pre-drilled holes, mounting brackets, and the overall portability of the solar panels.
- Amount of Power: Before buying any solar panels, it's best to know how much power you need so you know what to buy. Just charging your RV's battery only requires a small setup, but the more amenities you have, the more you might need. If you aren't sure, it's best to start small and increase later if required.
- Weight and Size: Some solar panel kits are very heavy. Depending on where you plan to secure your solar panels and what kind of RV you own, the overall weight and dimensions of the panels could be a determining factor.
- Efficiency: The different way in which solar panels are made affect efficiency and cost. If you're limited on space but don't mind spending more money, than buying a high-efficiency monocrystalline panel is a good idea. If you have room to spare but don't want to spend as much, then investing in amorphous or polycrystalline panels could be a better option.
