Abstract：The photovoltaic power generation of typical cities in four solar radiation intensity zones in China is simulated by using PVsyst software.The influence of factors such as the installation inclination angle of photovoltaic panels,array spacing and photovoltaic materials on the photovoltaic power generation under different solar radiation intensity zones is studied,and the significance degree of the influence of each factor is analyzed by using the range analysis method.The results show that the significance of the influence of each factor is as follows:Solar radiation intensity>photovoltaic material>array spacing>installation inclination angle.The optimal installation inclination angles of rooftop photovoltaic systems in Hami City,Beijing City,Shanghai City and Chongqing City are 40°,30°,20° and 10°,respectively,and the optimal array spacing of Hami City,Beijing City,Shanghai City is 3.39 m,2.26 m and 1.70 m,respectively.The influence of the array spacing of rooftop photovoltaic systems in Chongqing City is relatively weak.Heterojunction photovoltaic modules are solar cells that combine thin-film and crystalline silicon technologies and have relatively good power generation efficiency.
