| Abstract |
The field performance of a direct-coupled solar photovoltaic water pumping system that composed of a photovoltaic array directly coupled to a D.C. motor driving a centrifugal pump was studied. Data indicate that the photovoltaic modules operate at an instantaneous efficiency of about 34.93 % under Alexandria climate. The results of this study indicate that the solar photovoltaic systems are quit suitable for water pumping from low level of water. Approximately maximum of 4.932 m3/h water was collected on a specified day at solar insolation rate of 975 W/m2. The hydraulic pump output was 27.1 watt. The motor-pump efficiency was determined to be 23.43% and the system efficiency was 8.18 % at a water head 2 m. The factors that affected mainly the pump flow rate were solar radiation, static suction head and wind speed. Multiple regression analysis was used to establish pump performance model, which can be used conveniently to predict pump flow rate with determination coefficient equal to 0.9930. The experiments revealed that the pump could be used for small agricultural applications, which need water less than 29610 l/day, if the pump operates about seven hours during days of the months of May through September. This system for pumping water can be installed at farmers’ houses for providing drinking water or feeding water for a small livestock farm or for small greenhouse irrigation.
