Optimizing the performance of solar PV water pump by using Response Surface Methodology

Vipan Chand Waila, Abhishek Sharma and Mohd Yusuf


Diesel-powered irrigation pumps are widely used. However, due to the global increase in the price of oil, the hazardous pollutants released during combustion, the high cost of maintenance, and the short lifespan of conventional vehicles, innovators have been compelled to find an alternative. Scientists are now developing a solar-powered irrigation water pumping device. Solar is a good alternative because it can be used anywhere, even in remote areas. Studying what affects a solar photovoltaic water pump's efficiency is the primary objective of this effort. It was shown to be more economical, less harmful to the environment, and dependable than diesel- powered water pumps, requiring less maintenance and having a longer service life. In this investigation, the effects of AT (oC), SR (W/m2), SAA (degrees), and TA (degrees) on SPVWPS were investigated. In order to maximize the output response discharge (m3/hr) and the pump efficiency (%), the RSM was used to model to obtain optimal values of input parameters. At a parameter combination of solar radiation (451 W/m2), ambient temperature (27oC), surface azimuthal angle (-18o), and tilt angle (55o), the maximum discharge (48.7 m3/hr.) and pumping efficiency (58.8%) are reached (57o). It turned out that the formulated mathematical model could accurately predict the SPVWPS's performance and efficiency.
