When there are plenty of choices, some prefer looking for expert reviews to be able to compare different options. So, what should you pay attention to in RV solar panel reviews when looking for a system for your own camper van? Check specifications first. The most important characteristics of an RV panel are:
Size. Space is always a concern with RVs, so examine your roof and measure out the spot that can be used for panels. The average size of a solar panel is 65 x 39 inches.
Weight. Check the maximum weight that the roof of your RV can withstand. 40 lbs is an average weight of a solar panel.
Power output. The power that you need depends on your energy needs.RV solar panels usually perform at 60-80% of their rated power because it's hard to get a perfect positioning and angle for a module, so it often makes sense to
buy a few extra watts.
Panel type. Solar panels for RV can be monocrystalline, polycrystalline or thin-film. Crystalline modules are efficient and long-lasting. Thin-film panels, on the other hand, are cheap and flexible which makes them good for an RV roof with difficult configurations.
Efficiency. Efficiency determines how much sunlight a panel can turn into electricity. The higher it is, the better. The average efficiency of crystalline modules ranges between 17% and 19%. Thin-film panels usually have an efficiency of 10%-13%.
There are more details to consider when it comes to solar panels for an RV. Reviews mention all sorts of things: shading tolerance, performance at high temperatures, warranties and durability. The importance of these parameters depends on the climate in your area. Is it hot out there? Will your panels be overshadowed? Do hurricanes occur often in your land? Pay attention to those advantages of different models that are relevant to your situation. Now let's look at a few examples of what we think are the best panels for an RV in 2021.
