Photovoltaic power supplied to the utility grid is gaining more and more visibility while the world’s powers demand increases. In this paper we are defining a circuit-based simulation model for a PV cell in order to estimate the electrical behavior of the cell with respect to changes in environmental parameters such as temperature and irradiance. The PV system requires many special design considerations due to varying nature of the solar power generated resulting from unpredictable and sudden changes in weather conditions which change the solar irradiation level as well as the cell operating temperature of PV arrays. PV cell is the most basic element of photovoltaic generation units, which converts the solar energy into electrical energy. This paper focuses on a MATLAB/Simulink model of a photovoltaic cell. This model is based on mathematical equations and is described through an equivalent circuit including a photocurrent source, a diode and a series resistor. The developed model allows the prediction of PV cell behavior under different physical and environmental parameters. In addition, this paper outlines the working principle of PV module as well as PV array. So this completed model accepts irradiance and temperature as variable parameters and outputs the I-V as well as P-V characteristic. In order to validate the developed model, the simulation results are compared with the standard results and characteristic curves provided by the PV array manufacturer and they show excellent resemblance.
