Characteristics of Floating Photovoltaic Power Generation Based on Probability Statistics

摘要

In order to analyze the accurate power generation characteristics of the floating photovoltaic (PV) system, the same 2.5kW PV systems are installed on the surface of Dam water and the near ground, and the performance is compared. The output characteristics of the floating PV power generation according to the change of water temperature is analyzed by using the probability statistical technique in detail, and it is verified that the low temperature of the floating PV system module is caused by the cooling effect of water surface. From the comparative study between them, it is confirmed that the floating PV module temperature is lower than that of land based PV, so that the efficiency of the floating PV power generation is higher than that of the grounding PV power generation.
