With bifacial solar cells, both the front and rear sides are optically active. They are sandwiched between two approximately 2.5-mm-thick glass panels, creating stable modules with a greater solar yield than modules with just one active surface.Moreover, they take up less land space, meaning that the area on which they are installed can still be used for agriculture.

This space-saving installation has been made possible thanks to the patented mounting system from Berlin-based startup Next2Sun , which aims to build more network and environmentally-friendly open-space facilities. At the new facility in Saarland, the double-sided light-sensitive modules from Yingli and Sunpreme will be oriented to the east and to the west and erected vertically in rows at approx. 10 m intervals, thereby generating power both in the morning and in the afternoon on a minimum footprint.

The contracting authority and operator of the facility, which strives to generate 2 MW peak power, is Ökostrom Saar Wind GmbH, a subsidiary of Ökostrom Saar GmbH .
