A research on wter pumping with solar energy

Photovoltaic water pumping (PWP) systems are particularly suitable for water supply in remote areas where no electricity supply is available. Since the high initial costs of the PWP systems, it necessary to dimension photovoltaic installations as accurately as possible. In this study, some technical parameters of the photovoltaic (PV) water pumping system including submergible pumps have been investigated. For this purpose, the electrical properties such as current, voltage and power and efficiency of the PWP system consists of four array including 72 PV cells were determined. Water pumped, hydraulic powers and efficiencies of the submergible pumps worked with PV cells were calculated.While the electrical power generated the single PV module was 656,23 W, the average electrical power of the PV system was 2982,72 W. The average electrical efficiency of the PV system was 17,86%. Water pumped, hydraulic powers and efficiencies of the submergible pumps were 21,6 ? 28,8 m3/h, 1270,58 ? 1694,11 W ve % 42 ? 56,6, respectively.
