In the search for new options for the establishment of the energy matrix of Brazil, the Grid-Connected Photovoltaic Systems (SFVCR) are configured as an alternative to urban centers, because they allow the power generation at distributed mode, that is, generate energy at the place where it will be consumed and inject the surplus energy into the network. Faced with the prospect of installing Grid-Connected Photovoltaic System, the objective of this research is to characterize this type of photovoltaic system and also, analyze the results in terms of productivity parameters, such as Yield, Performance Ratio and Capacity Factor of six grid-connected systems that are installed in Curitiba. The radiation data used to calcute those parameters has been acquired from Instituto Nacional de Meteorologia (INMET). This paper highlight that the Parana state has 810 SFVCR (until April 2017) in operation, which stands for 5MW and Curitiba has 170 SFVCR, 865 kW in operation, and 80% of them are installed in residences. In addition, 98% of those systems use multicrystalline modules, 75% use single phase inverters and 95% of these use inverters transformerless, because the losses in the conversion process are reduced and the equipments are more compact and have more technology than the inverters with transformer. So, the main trend of photovoltaic energy market is to use transformerless inverters. The results obtained shows that the inverters’choice and the installation mode of the photovoltaic modules are important factors to maximize the photovoltaic system’s performance. In the end, the results demonstrates that the SFVCR contribute to distributed power generation and should be use in the elaboration of public policies with the purpose of encouraging projects and research in the photovoltaic energy’s area, aiming the dissemination of this renewable source of energy in Brazil.
