A circuit simulation model of photovoltaic array was developed based on Matlab / Simulink soft-ware,the effects of solar insolation,temperature and photovoltaic cell parameters on electrical behavior of photovoltaic array were analyzed,and the output characteristics of photovoltaic array under dynamic irra-diance condition were simulated and calculated. The simulation results indicated that irradiance,tempera-ture and series resistor have significant impact on open-curcuit voltage,short-circuit current,volt-am-pere characteristic,output power and optimum working point of photovoltaic array. The developed model is capable of accomplishing dynamic simulation of photovoltaic array.
