For those putting together a long term solar setup on a caravan or motorhome who want to know they have access to the best and most reliable panels on the market, monocrystalline types are probably the best bet. They’re costlier than polycrystalline options, but their longevity, performance, and efficiency mean that they’re a good buy over a longer period of time. When you want to be sure you’re producing the highest wattage per square foot, these are the modules to rely on. We only sell monocrystalline panels. All of our panels come with a one year workmanship warranty and five year power output warranty.
