Back Contact Solar Module - proven technology for higher yields.

BSP Back Contact solar modules stand for maximum performance in a minimal footprint. With an efficiency of up to 24.7 percent, they are among the most efficient modules in their class. This is made possible by advanced back contact technology, in which all electrical contacts are located on the back of the monocrystalline solar cells. The front remains fully light-sensitive, without any shading from conductive traces. This increases energy yield, boosts efficiency, and results in a clean, deep black appearance.

Thanks to their more compact dimensions and lighter weight, BSP modules are particularly suitable for mobile applications such as campers, motorhomes, or boats – anywhere high power is required in a limited space. Integrated bypass diodes ensure a stable current flow even in partial shading.
