Abstract
Belal Mohamed Swidan: Performance evaluation of solar photovoltaic pump operating landscape system. Unpublished M.Sc. Thesis, Department of Agricultural Engineering, Faculty of Agriculture, Ain Shams University, 2017.
Field test had been carried out in 2016 – 2017 (August – February) at Menofia governorate, Egypt. 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. Measurements were taken every hour starting from 8:00 a.m. to 4:00 p.m. through randomly selected days during the period between August and February. Results show relation between the solar radiation and the output electrical power, hydraulic power, pumping rates and the efficiency of the system.
System evaluation was made by estimating the intensity of solar radiation, Photovoltaic output power and the hydraulic power generated. The results show that the maximum hydraulic output power was 14 W where the electrical power consumption was 140 W and the PV output power was 712 W at solar radiation intensity of 841 W/m². The maximum efficiency recorded for the overall system was 0.41% where the photovoltaic generator and pumping system efficiencies found to be 14.98% and 14.21% respectively.
