摘要：The aim of this paper is to highlight the parameters that interfere in the performance of grid-connected PV systems. In the three years of analysis, the energy generated and the solar radiation were locally monitored and used to calculate the performance parameters, such as Final Yield, Performance Ratio and Capacity Factor. The results obtained are related to the three years of operation of the Green Office PV system located in UTFPR. The case study compares the monitored PV system in Curitiba, as well as the literature cases in Santa Catarina and Pará states, in order to analyze the photovoltaic systems performance in several conditions. The results were very close in each case, although in Pará PV system case the highest final yield is explained by its location, which is close to the Equator’ line, therefore there are the highest solar radiations in Brazil. In the end some suggestions were made to improve the GO’s grid-connected PV system, because it has revealed a significant performance decrement, mainly due to partial shading losses.
