BSP 100L Black Lightweight | Lightweight Back Contact Solar Module with 100Wp

BSP Lightweight Solar Module – Maximum performance at minimum weight

Whether on the roof of a camper van, on board a boat, or in a garden shed: BSP Lightweight solar modules offer the performance of classic BSP modules – with significantly reduced weight. This is made possible by a lightweight design and modern cell technology specifically developed for mobile and weight-sensitive applications.

Thanks to back-contact technology, all contacts are located on the back of the solar cells. This allows for more active surface area to be used for light absorption, while simultaneously minimizing shading losses and the formation of hotspots. Even with partial shading, the energy yield remains stable.

With 33 monocrystalline cells , a power output of 100 Wp , and pre-assembled MC4 connectors , the module is quickly ready for use and ideal for off-grid power systems. The open-circuit voltage of 21.60 V is compatible with all common battery systems.
