A high quality mono-crystalline solar panel, the UPG 40-watt solar module is perfect for smaller applications such as RV's, or mobile homes. With a superior efficiency rating (14.5%)—this module is a good choice if space is an issue. The module’s junction box will save you the expense of buying additional adapters.
Some would argue that the module's mono-crystalline PV technology is superior to polycrystalline and amorphous thin film technologies. Invented in 1955, it is the original PV technology. Easily identifiable by uniformly stacked rounded cells, it has a single and continuous crystal lattice structure with practically zero defects or impurities.
