A photovoltaic generator is subject to diverse variations in solar intensity, surrounding temperature or load, which alter the optimal operation point. Thus, one must analyze its behavior regarding such variations in order to optimize its functioning. This paper aims at modeling a photovoltaic generator regarding the features provided by the manufacturer and simulate it, using, for that purpose, simulation and curve digitalization programs (Simulink of Matlab), analyzing its behavior with regard to the temperature and solar intensity variation, comparing the obtained curves to those provided by the manufacturer. The obtained results were satisfactory, the model used being valid for photovoltaic generators simulation.
