Modelagem e Simulação de Células Fotovoltaicas: Metodologia e Análise Comparativa

Abstract

Mathematical models play a crucial role in determining the parameters of solar panels, allowing for a precise analysis of the behavior of photovoltaic modules. This study compares two mathematical models for this purpose and highlights the importance of continuously updating these models for a better understanding of solar panel operation. The Newton-Raphson method was employed to determine the parameters of the models, and representative circuits were assembled in LTSpice for different levels of irradiance, resulting in the expected behavior. The choice of CIGS technology is highlighted due to its advantageous characteristics and good efficiency. The analysis revealed that the diode model provides a good approximation, thanks to the correct numerical method for determining values not provided by the manufacturer.
