Research on Photovoltaic Array Characteristics with Partial Shadow

In order to study the working characteristics of PV system under different working conditions, in this paper we analyze and simulate the model based on the mathematical model of photovoltaic cells and the output characteristics of PV arrays under different illumination and temperature. We also study the output characteristics of the monolithic components of the PV array, and analyze the output voltage, current and power output in different lighting conditions in theoretically. The experiment selects different occlusion method for photovoltaic cells in series array, and results are in agreement with the simulation results. This paper has practical significance for photovoltaic systems engineering.
