Application of Hybrid Solar and Wind Energy Generation for Paddle Wheel Aerator

Abstract

Abstract At the coastal areas of South Sulawesi, Indonesia, there are many of villagers work as fisherman, shrimps and fish farmers. Most of them use aerator paddle wheel that are operated by high wattage motors that are ranged from 750 Watt to 1000 Watt. Some others use gasoline engine for one aerator every day. Consequently, the use of high wattage motors will cost the farmers and the use of gasoline will contribute to the air pollution. Therefore, it is necessarily important to invent a renewable base energy source for aerator which in turn economically effective that in the same time could apply the energy diversification. Fortunately, solar and wind potency are quite promising in the area. In this paper, an investigation, examination and application of hybrid solar-wind turbine generator are conducted and applied to aerator paddle wheel for shrimp’s pond. The required energy is 420 Wh/day. The measured average wind speed at Pancana Village is ranged from 3.25 m/s to 5.28 m/s. The averaged solar radiation potency in the village is 975 W/m2. The hybrid system is a combination of two 150 Wp solar panels and 500 W wind turbine. The experimental result show that the solar panels could generate energy by about 370.54 Wh in average, while wind energy could generate 165.60 Wh energy every day. Therefore, it can be concluded that the required energy of the aerator at average paddle wheel of 80 rpm can be fulfilled although solar energy is dominant as energy supplier.
