Output Characteristics of PV Array under Different Insolation and Temperature

The output power of a photovoltaic (PV) array is affected by insolation and temperature. It is important to improve the output efficiency of a PV array as the output power of the PV array is affected by intensity illumination and temperature. The simulation model of PV module in this paper based on Simulink is built in accordance with PV module´s physical and mathematical model. The Simulink model can be used to simulate output characteristics of the PV module under different insolation and temperature. Meanwhile, this model can be applied to cases of other powers and used to study module´s series and parallel characteristics. The simulation results show the characteristics of series and parallel PV array under non-uniform insolation and temperature conditions. The analysis will help to design optimum configuration of PV array as well as choose suitable MPPT methods.
