Abstract he efficiency of PV systems varies in performance due to several factors, such as module efficiency, PV arrays, PCS, solar irradiation, ambient temperature, and wind speed. In this study the cooing effect of floating PV is mainly discussed. In order to examine the cooling effect of reservoirs, three laboratory experiments are performed by controlling chamber temperature. The first experiment was conducted to determine the amount of light reflected from the water surface compared to the ground. Secondly, the representative temperature and humidity were set for each season and the temperature difference of module between ground and water conditions is measured. The third experiment was a comparative experiment of the generation amount between ground and floating PVs according to the change of the outside temperature. In addition, a mathematical model was selected and compared with experiment results.
