Floating PV power plants with solar modules mounted on floats on bodies of still water or at sea show very dynamic growth worldwide (over 1.1 GW of installed capacity in mid-2018). Germany has huge technical potential for this technology with its pit lakes, flooded former gravel pits and reservoirs. The advantages of FPV include cost-effective implementation of large-scale plants, an increase in PV efficiency due to cooling effects of the water and a reduction of the evaporation rate that lowers water losses.

Fraunhofer ISE Analyzes Potential of Solar Power Plants Located on Pit Lakes

Commissioned by the renewable energy developer BayWa r.e., the Fraunhofer Institute of Solar Energy Systems ISE investigated the technical potential of floating photovoltaics (FPV) on pit lakes in former lignite mines in Germany. Such FPV plants that basically float on man-made lakes can help to alleviate the competition for land use and help expand PV capacity in Germany.
