Abstract: The photovoltaic module is represented by an equivalent electrical circuit with five or seven parameters depending on the complexity of the model, these parameters are unknown and crucial to predict the performance of a PV module. In this paper, in order to extract the seven parameters of double diode model a hybrid method, which combines analytical and numerical methods, is proposed. The analytic modelling is obtained by combining the equations of three characteristic points which are the open circuit voltage, the short circuit current and the maximum power point. While the numerical method is employed to find the value of series resistance and of the ideality factors in which the computed and the datasheet powers are equal, the other parameters are computed afterward using analytical equations. The validity of the proposed method for various PV modules has been analysed under different temperature and irradiance conditions and the obtained curves were compared with experimental data. The results confirm the advantages of the hybrid method, furthermore, the absolute error and the RMSE affirmed the accuracy of the proposed approach.
