Resumen
The energy performance of a photovoltaic system (PV System) depends strongly on how it was designed, that is, on its inclination, orientation, technology of the PV modules and inverters, on the climatic conditions and on the place where the SFV was installed. Therefore, this work had as main objective to evaluate and compare the productivity and performance rates of 37 micro / mini photovoltaic systems connected to the power grid with different technologies (60, 72 and 144 cells PV modules, traditional, Half Cell and PERC. Traditional static converters, converters with optimizers and microinverters) and also different manufacturers of static converters (SolarEdge, APsystems, Fronius, B&B Power, Reno, ABB, GoodWe) and photovoltaic modules (Canadian, DAH Solar, Risen, Jinko), through monitoring of its energy performance parameters such as: the Global Yield or Performance Rate (Performance Ratio - PR) and Specific Energy (Final Yield - Yf). A total of 37 installed photovoltaic systems were considered, mostly installed in the eastern region of the state of Minas Gerais. 4 systems were evaluated separately in a first stage and the other 33 in a second stage. The energy results obtained show the advantages and disadvantages in the use of different technologies in the photovoltaic market which can impact the final decision of a project.
