Abstract: Currently,against the background of global advocacy for energy transformation and promotion of the use of clean energy,after hydroelectric power generation,PV power generation has become an important source of electricity for countries around the world. With the rapid development of the PV industry in recent years,the construction of ground PV power stations has gradually become saturated,and many problems and shortcomings have emerged,and water surface PV power stations are being developed and used by various countries due to their many advantages. Compared with water surface PV industry in countries such as Japan and the United States,water surface PV industry in China started relatively late but developed rapidly. Currently,China has become the country with the highest installed capacity of water surface PV power generation in the world. On the basis of introducing the application prospects of water surface PV power generation in China,this paper introduces the main advantages of water surface PV power stations compared to ground PV power stations,as well as the development status of the water surface PV industry in other Asian countries,and puts forward suggestions for the future development trend of the water surface PV industry. The analysis results show that water surface PV power generation is being widely promoted by more and more countries because of its advantages of improving water quality,reducing water evaporation,improving the power generation efficiency of PV power generation system,not occupying land resources,and convenient construction,operation and maintenance.
