Abstract: The present work was developed at the Assis Gurgaz School of Engineering (FAG) and aimed to determine the efficiency of a wind-photovoltaic hybrid system for electricity generation. Three 140 W photovoltaic panels were installed to assess the generation of photovoltaic energy and the efficiency of its participation in the hybrid system. A small wind generator of 2000 W was used to evaluate the production of local wind energy, establishing the wind contribution in the hybrid system. Energy consumption was achieved with the installation of four 60 W incandescent lamps. The measurements of the meteorological quantities were obtained with the installation of a Micrometeorological station and the electrical data, with the use of a datalogger. Four batteries of 100 Ah each were installed to store the surplus electricity production and feed the installed load, when the system production was insufficient. A voltage divider, a rectifying bridge and an electronic device were installed to make it possible to record the quantities in the datalogger. The system showed efficiency of 12.5% for the generation of energy by the photovoltaic solar source, 18.7% for the wind generation and 11.9% for the entire hybrid system. The participation of the photovoltaic matrix contributed with 75.2% of all energy generated, while the wind matrix presented a contribution of 24.8%.
