Implementação e verificação experimental do modelo de cinco parâmetros para módulos fotovoltaicos em Fortaleza Ceará

Abstract

Several mathematical models have been proposed in the literature to represent a photovoltaic (PV) module. This paper aims to present the modeling, for the conditions found in Fortaleza, CE, and, later, the experimental verification of two 20 W modules, one monocrystalline (mSi) and another polycrystalline (pSi), using the 5 parameter model (M5P). In this model, the output current is obtained through the calculation of five variables, these being dependent on some reference values of the PV module. The currents calculated by the simulations for different irradiance and temperature conditions of the module are compared with the values measured in the two systems, showing that the model is able to predict the output current quiteeffectively, with mean errors of 5.46% and 5.79% for the pSi and mSi modules, respectively.
