Matlab/simulink model for simulation of photovoltaic module

Abstract

This paper introduces a circuit-based simulation model for a Photovoltaic (PV) cell in order to estimate the electrical behavior of the cell with respect to changes on environmental parameter of temperature and irradiance. An accurate PV module electrical model is presented based on the Shockley diode equation. The model was developed using MATLAB/SIMULINK, a simulation program that provides graphical interface for building models as modular block diagrams, and accepts irradiance and temperature as variable parameters and outputs the l-V characteristic. A particular typical 80W solar panel was used to evaluate the model, and the results were compare with manufacturer’s published curves and showed excellent correspondence to the model.
