A Proposed Model of Photovoltaic Module in Matlab/SimulinkTM for Distance Education

This paper define a circuit-based simulation model for a PV cell in order to allow estimate the electrical behavior of the cell with respect changes on environmental parameter of temperature and irradiance. An accurate PV module electrical model is presented based on the mathematical equations. The general model was implemented on MATLAB/Simulink environment, and accepts irradiance as variable parameters and outputs the I-V characteristic. A particular typical solar panel was used for model evaluation, and results was compare with points taken directly from the manufacturer's published curves and show excellent correspondence to the model. With this proposed module different types of PV modules could be developed and students could be investigate and learn the P-V or V-I characteristics easily. Furthermore, a by-pass diode is added to the PV cell design with this addition, in different insulation combinations will be able to investigate likewise partial shade.
