ECTIVE BSP 120 Black Monocrystalline Solar Panel 120W

The BSP Back Contact Solar Modules – Maximum Performance in a Minimum Space.
With an efficiency of up to 24.7%, BSP modules extract more from the sun than conventional solar modules. This is made possible by innovative Back Contact technology, where all electrical contacts are moved to the rear side of the cells. This leaves the cell front completely transparent to light – for higher yield, 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, wherever high performance is required in a limited space.

The 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 yield but also aesthetics. The two integrated bypass diodes ensure that the module remains powerful even with partial shading, making it ideal for campers or roofs with superstructures.

Technology & Efficiency

• Back Contact technology – all contacts on the rear for maximum light yield
• Monocrystalline solar cells – durable, powerful, and temperature-resistant
• Efficiency of up to 24.7% – significantly more than conventional modules at approx. 21.4%

Compactness & Design

• Smaller dimensions and less weight – same performance in a smaller area
• Deep black appearance – lower reflection, modern look

Performance in Shading

• Two bypass diodes – stable current flow even with partial shading
• No front contacts – reduced susceptibility to hotspots and power loss

Technical Features

• 120 W nominal power – ideal for mobile off-grid setups and autonomous power supply
• Pre-assembled MC4 connectors – easy, secure, and fast installation
• Protected junction box (IP65) – reliably protected against dust and jet water

Reliability & Warranty

• 25-year warranty on 80% nominal power – for long-term investment security
• Robust & durable – developed for continuous outdoor use

The BSP Back Contact modules are the right choice for anyone who doesn't want to compromise on solar technology. Maximum efficiency, less space, stylish design – all with a 25-year warranty. Whether on a motorhome, boat, or garden shed: once you've upgraded, you won't want to go back.
