Analysis of Variables in Systems Hybrid Photovoltaic Wind in Rural Energization

Abstract

The search for renewable energy sources is becoming something of great importance in the face of conventional energy sources. Clean and renewable production systems is gaining incentive to search for pieces of institutions and the government, especially the sources like the sun and the wind. There are plenty of both sources throughout the Brazilian territory and its use becomes interesting to isolated regions due to lack of network installation that enables access to electricity. This study investigates the production of energy from a hybrid system composed of photovoltaic panels and a wind turbine. These systems are adequate to meet the energy needs of isolated areas due to the high cost of electrification places with low demand and difficult to access. The project was developed at the Center of Alternative Energy and Renewable NEAR Rural Energizing Laboratory of the Department of UNESP Rural Engineering, Faculty Agricultural Sciences, Lageado Experimental Farm, located in Botucatu, Sao Paulo, Brazil, which was used three photovoltaic I-100 Isofoton with nominal power of 100Wp each, for a total installed 300Wp and a wind turbine AIR X-rural model SOUTHWEST WINDPOWER with nominal power of 400 W, which was obtained for a year energy production data using this system. In general, energy production ranged from 34.8 to 209 watts hybrid photovoltaic system and the wind. It was possible to observe the complementary mode of energy production systems analyzed, since the photovoltaic panels have higher yield during the day, while the wind turbine has energy production at night.
