Estudo comparativo do desempenho de sistemas solares fotovoltaicos com otimizadores de potência que estão sujeitos a sombras parciais

Abstract

With the growing energy demand, renewable energy sources are gaining more and more prominence, especially photovoltaic solar energy This work aimed to study the behavior of a solar photovoltaic system submitted to partial shading, and evaluate the real gain of using power optimizers, for this it has a photovoltaic plant already in operation capable of sending detailed daily reports of the energy generated and the power variation during the tests. To evaluate the performance several technical and economic indicators were used such as net present value, investment rate of return, payback, system yeld and optimization efficiency By analyzing the indicators resulting from the two tests performed, it was possible to measure the real gain that the implementation of the power optimizer can bring to the system, making the benefits of its use increasingly known, encouraging its use. Resulting in a significant improvement in the technical and economic indicators of all test scenarios.
