Condições para maximização da produção de energia elétrica em painéis fotovoltaicos

Abstract

Photovoltaic modules have a great power generation capacity in Brazil, since this country has a high incidence of irradiation. Another factor that supports the idea of installing photovoltaic panels is the high cost of charging electricity from utilities and the environmental impacts caused by forms of energy generation that harm the environment. This fact boosts and enables investments by the Brazilian government in distributed generation. Thus, there is a need to understand the behavior of the photovoltaic system when influenced by the environment, and for that, it is necessary to comply with the parameters of the photovoltaic panels through the Gauss­-Seidel iteration with the intention of quantifying and qualifying the effect of irradiance, temperature, latitude, longitude and other factors that influence the efficiency of solar panels. During this study, different models of photovoltaic panels were applied to obtain convergences. Finally, the objective is to validate the possible way to create conditions for maximizing the production of electric energy in photovoltaic panels through algorithms that show all the external influences of the photovoltaic modules. Another application of the algorithms of this project was the optimization of the number of modules per string that an inverter can support, resulting in the output of the energy generation yield of the photovoltaic modules.
