With an efficiency of up to 24.7%, BSP modules extract more energy from the sun than conventional solar modules. This is made possible by the innovative back-contact technology, in which all electrical contacts are located on the back of the cells. This allows the front of the cell to be completely transparent – resulting in higher yields, greater efficiency, and an elegant design.
Due to their lighter weight and more compact dimensions, BSP modules are ideal for mobile applications such as campers, boats or motorhomes, anywhere high performance is required in a limited space.
BSP solar modules with monocrystalline solar cells and back-contact technology are the answer to modern demands for performance, efficiency, and design . With an efficiency of up to 24.7%, they are among the most efficient modules in their class. The absence of visible front contacts not only improves light output but also enhances the appearance. The two integrated bypass diodes ensure that the module remains efficient even in partial shading, making it ideal for campers or roofs with superstructures.
