Hybrid Power Generation by Solar & Vertical Axis Wind Turbine: A Review

Abstract: Renewable energy sources are seen as next generation source of energy for meeting rising energy demands and depleting fossil fuels. Solar, biomass, geothermal, hydro-electric and wind are the renewable which can produces a huge amount of power. The power from wind current can be extracted using a vertical axis turbine/horizontal axis turbine. Vertical axis turbine is capable of extracting power form wind regardless of the direction of flow. The solar PV cells absorb the radiation of sun and converting it into the electrical power. The wind mill is capable to extracted energy in day and night time while the solar PV cell is capable to get power only during day time. The combination of this hybrid system will be beneficial in future aspects. The objectives of this paper is „Hybrid power generation by using solar cell /solar energy and wind mill energy, with the help of solar tracking and vertical axis wind turbine‟. The VAWT (Vertical Axis Wind Turbine) can tap wind energy from any direction and VAWT are more profitable in nature. That why we have used the VAWT with solar tracking hybrid power generation. The vertical axis turbine has much better self- starting characters and better conversion efficiency at lower flaw speed. In this we are used savonius type vertical axis turbine produce higher torque and have lower cut in speed. This paper deals with the hybrid power generation by using VAWT turbine and solar tracking.
