Mathematical Modeling and Simulation of Photovoltaic Solar Module in Matlab-Mathworks environment

Abstract — This paper presents a mathematical modeling and simulation of a photovoltaic solar module. Mainly an accurate mathematical model for computing Maximum Power output of a photovoltaic PV module is presented. The model for PV panel is developed based on the single-diode photovoltaic model, found in the literature, including the effect of the series resistance. A typical 60 W photovoltaic panel is selected for simulation in Matlab-Mathworks environment. The essential parameters, required for modeling the photovoltaic module, are taken from datasheets provided from manufactures’. Current-Voltage and Power-Voltage characteristics are obtained, for the selected module, from simulation and compared with the experimental curves. On the other hand, this model is used to compute and to investigate the variation of Maximum Power output of a PV module with temperature and irradiance intensity levels. A validation of the proposed mathematical model is performed by an interactive analysis and comparison between simulation results and the typical PV module datasheet. The simulation results are well matched with the experimental data.
