Reliable cell technology
Free Energy Europe produces stable and reliable amorphous silicon cells. After initial stabilization during the first two months of outdoor use, the amorphous silicon cell will be stable for decades. The expected lifetime of the advanced amorphous silicon solar cells is at least 20 years.

High energy yield
The amorphous silicon solar cells, produced by Free Energy Europe, function better than crystalline silicon solar cells in partial or indirect sunlight. Tests have shown that the annual energy output is approximately 15 % higher per rated Watt-peak power.

Outdoor performance
The outdoor performance of amorphous silicon solar panels depends primarily on their protection against corrosion. Our 4-th generation solar panels use an injected polymer frame, with a very high moisture barrier. This technology has been developed internally and is unique to the Free Energy Europe products. This advanced framing technology makes our solar panels reliable for outdoor use.
