Research on the Optimal Inclination Adjustment Scheme of Supplementary Photovoltaic Power Station

The power generation efficiency of large-scale photovoltaic array is closely dependent on the solar radiation intensity. This paper takes a photovoltaic power station in a specific longitude and latitude area in southwest China as the research object. First, calculate the tilt angle and Irradiance of the photovoltaic array by analyzing the shadow shading of the north-south PV module support. Through PVsyst simulation of photovoltaic system optimal tilt operating conditions, this paper discusses the optimal adjustment times and adjustment time scheme. Finally, considering the electricity quantity, electricity price and operation and maintenance cost, the comparison and analysis of the above indicators gives the best income of the photovoltaic power station and the best inclination of the photovoltaic array.
