Researches are showing that photovoltaic cell equivalent model parameters are not constant and are sensitive to climatic conditions changes. An improved algorithm for multi-photovoltaic cells manufacturing technologies to estimate those parameters is presented in this paper. The method allows a dynamic model for the PV cell according to different climatic conditions. This method shows a better performance of the model for several technologies (poly-crystalline, mono-crystalline and amorphous) of the PV module. Simulated I -V curves are compared to experimental characteristics and other estimation methods for different PV modules and different technologies. Some considerations about the impact of the variations of these resistances on the PV module performance are drawn.
