摘要： This paper presents the implementation and testing of SPV powered 0.5HP AC water pumping system. DC pumps are widely used in SPV based systems. However, the cost employed for DC pumps is much larger in comparison to conventional AC pumps. In the proposed system inverter is designed for 400 W SPV panel connected to 0.5HP pump. The experimental setup is in Energy Park, Basaveshwar Engineering College built (Autonomous), Bagalkot, India. Further, performance analysis of the SPV water pump under varying conditions of solar radiation is carried out. Solar radiation, SPV output, Inverter output, Inverter efficiency, Flowrate from pump, Hydraulic power output and Pump efficiency are experimentally obtained and tabulated. Performance results revealed that, proposed model delivers 45-50 liters of water per minute from the depth of 3m water tank. Maximum efficiency of inverter and entire unit is obtained at highest solar radiation of 1195W/m2. The results indicate the efficient working of the implemented system for at least 4 hrs, between 11:00am to 3:00pm of a day. The proposed the cost and decreases dependency on conventional energy sources, while satisfying the water requirement in small scale agriculture and gardening.
