| Abstract |
Photovoltaic(PV) power plants are growing all over the world as a promising renewable alternative to generate electricity. Floating PV(FPV) systems have been researched as a new concept in PV industry to mitigate negative environmental impacts instead of installing conventional PV facilities on land. It is well-known(commonly understood) that the efficiency of FPV is higher than that of ground mounted one due to the water cooling effect. However, there are not many sufficient and numerical supporting data to prove the cooling effect to of (over) FPV. Both two FPV sites in Hapcheon-dam and three ground-mounted PV sites near Hapcheon- dam are selected to compare their efficiency with three methods. The three solar radiation sources are analyzed by statistical methods, one of which is selected to use. The selected radiation is applied to evaluate the efficiency of both FPV and ground PV from 2013 to 2018. |
