Efficiency Analysis of Solar Photovoltaic Panels for Water Lifting Pump

Abstract

Solar technology is mainly used for lifting water in regions where electricity grid has not reached yet. The objective of this research work is to perform the efficiency test of solar panels used for the water lifting projects. A suitable location was chosen for the test and arrays of solar panels were used for the operation of the pump. The efficiency of panel was calculated using the output power supplied by the solar panel to the motor. The delivery discharge of motor was noted for the operation of motor. It was seen the solar panel used for the testing had the maximum efficiency of 18 % only. The shading effect was also considered for the verification of power production of solar panels.
