Abstract
Most landscapes requires the water essentially, water pumping consumes a significant amount energy. The study carried out to evaluate the performance of a solar water pumping system for the purpose of operating landscape system. The system consists of a centrifugal water pump connected directly to DC electric motor that which connected directly to a solar photovoltaic generator. Field test had been carried out at Menofia Governorate, Egypt. Measurements were taken every hour starting from 8:00 AM to 4:00 PM through randomly selected days during the period between August 2016 and February 2017. Results show the relation between the solar radiation and the output electrical power, hydraulic power, pumping rates and the efficiency of the system. System evaluation was carried out by estimating the intensity of solar radiation, Photovoltaic output power and the hydraulic power generated. The PV output power was 712 W at solar radiation intensity of 841 W/m². Also, photovoltaic generator and pumping system efficiencies were 14.98% and 14.21% respectively.
