【 摘 要 】

Photovoltaic facility agriculture system can effectively alleviate the contradiction between limited land and Photovoltaic power generation. It's flexible to create suitable environment for crop growth, and generate electricity over the same land at the same time. It's necessary to set appropriate solar panel angle to get more solar energy. Through detailed analysis and comparison, we chose the Hay's model as solar radiation model. Based on the official meteorological data got from Haikou Meteorological Bureau, and by comparing the amount of radiation obtained at different tilted angles per month, the optimal placement angle of PV panels at different seasons in Haikou was obtained through calculation, and the optimal placement angle from April to October was also obtained. Through optimized angle and arrangement of solar photovoltaic panels, we can get greater power efficiency.
