Computer-aided model parameter extraction of photovoltaic modules using SPICE

An approach is developed in the paper to model parameter extraction of photovoltaic (PV) modules based on manufacturer's datasheet characteristics. The model parameters are obtained simultaneously for any environmental conditions (irradiance and temperature). The computer realization of the parameter extraction procedure is performed using the general-purpose circuit simulator PSpice and postprocessing in the graphical analyzer Probe to obtain the model parameters satisfying the defined requirements. The model accuracy is validated for different irradiance and temperature conditions. The implementation of the parameter extraction procedure of PV modules in standard circuit simulators such as PSpice allows its accessibility for the designers of PV systems.
