This paper describes a method of modeling and simulation photovoltaic (PV) module that implemented in Simulink/Matlab. It is necessary to define a circuit-based simulation model for a PV cell in order to allow the interaction with a power converter. Characteristics of PV cells that are affected by irradiation and temperature are modeled by a circuit model. A simplified PV equivalent circuit with a diode equivalent is employed as model. The simulation results are compared with difference types of PV module datasheets. Its results indicated that the created simulation blocks in Simulink/matlab are similar to actual PV modules, compatible to different types of PV module and user-friendly.
