【Abstract】 Photovoltaic power generation is vulnerable to the impact of the external environment to failure, resulting in a significant decline in output power. Based on the research of single solar cell, the influence of local shadow on the output characteristics of PV module is analyzed and studied by theoretical model analysis, simulation and experimental test. In this paper, the output characteristics of photovoltaic array under different illumination, temperature and occlusion distribution are simulated using Matlab/Simulink software, and the results of maximum power point location changing with the external conditions are obtained.更多还原
