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.
