Generalized SPICE model of photovoltaic modules

In the present paper, a generalized SPICE simulation model of photovoltaic modules is developed, valid for operating conditions of solar irradiance and temperature different from nominal conditions. An extraction procedure for model parameter determination is proposed using datasheet characteristics of the modules. In order to improve the model accuracy, the values of the voltage V_mp and the current I_mp corresponding to the maximum power point MPPT, are also used as input data. The computer realization is performed in the Cadence Capture and Cadence PSpice environment. The description of the computer model is presented. The verification of the developed SPICE simulation model of PV modules confirms its validity and accuracy.
