A simulink based generalized model of PV cell / array

This work proposes a Simulink-based Model of a photovoltaic (PV) system using the two-diode model of a PV solar cell. The series and shunt resistance of the solar cell are estimated in this model by an efficient iteration method. The number of required input parameters are four and are based on the available information from the PV module datasheet. The developed model allows the user to predict a PV cell´s current-voltage and power-voltage characteristics curves by varying sunlight, cell temperature, ideality factor and series resistance value. The model is also applicable under partial shading/module mismatch condition. The characteristics curves obtained by the simulation of the proposed model is matched with the data provided by the manufactures.
