Made by melting raw silicon, polycrystalline solar panels come at affordable prices that make them highly sought after by a number of budget-minded RVers. Being low-cost, models of the type happen to be well-suited for big applications. As for the shortcomings, polycrystalline solar panels have mediocre efficiencies. In addition, many products with polycrystalline solar cells don’t handle heats particularly well which means they may fail early if exposed to extreme temperatures.

2. Monocrystalline Solar Panels

Using pure silicon, monocrystalline solar panels have excellent efficiencies compared to other types of panels. Moreover, products of types endure high temperatures well so they would be outstanding choices in a wide range of travels. The monocrystalline solar cells also work like a charm in conditions like partially shaded, low light, … In exchange, monocrystalline solar panels tend to be accompanied by relatively expensive price tags, hence, you need to have a fat wallet to get them.

So to put it plainly: the higher the efficiency, the more energy would be produced. The efficiency of the average panels on the market stays around 15% but in advanced models, it may rise well above 20%. Take into account the power consumption of the appliances you have on your vehicle in order to determine a firing efficiency for your solar panels.


In general, for ideal sunlight exposure, RV-oriented solar panels tend to be installed on the roof of recreational vehicles. Thus, RVers must give the sizes of the panels some thoughts before putting things together. If you have solar panels with suitable dimensions, optimizing the available space on the roof is going to be just a walk in the park.
