Análise do fator de desempenho entre sistemas de geração fotovoltaica utilizando micro inversores e inversores com string

Abstract

The purpose of the monograph is to compare the losses and evaluate the performance between photovoltaic power generation systems operating with micro inverter and string inverter. Based on articles, books, class notes, support sites and technical data of the equipment, the literature review brought the scenario of renewable sources in Brazil’s electric matrix, concepts of photovoltaic technology and its architectures and the main factors of loss in photovoltaic systems. . The analysis included the study of the performance of 4 plants in operation for more than one year in the same mesoregion and also the influence that the losses cause on the merit index final result through the SAM modeling software for photovoltaic systems. The results show that regardless of the architecture used, their performances are very close and the losses that are explicit do not depend on the architecture employed but on external factors.
