In this study, the cell behavior in a photovoltaic (PV) module will be investigated by using two electrical characteristics models of mono-crystalline solar cells: (i) the single diode model, and (ii) the double diode model. Several of the used models parameters are not provided by the manufacturer. The identification of internal parameters of the PV cell is performed by means of research algorithms using data provided by the manufacturer datasheet. Moreover, influences and effects of temperature and irradiance level variation are studied then compared for the proposed models. Simulations Results are compared to those provided by JAC M5SF-2 cell's datasheet. Then, the accuracies of proposed models are validated against experimental tests under the real operating conditions. Results show an acceptable and close similarity with the data issued by the manufacturer data. Identification algorithms, based on the manufacturer data, can thus, be very useful for researchers or engineers to define quickly and easily the internal parameters of any solar cell.
