| The experimental work was carried out at a private farm in Nubariah, Al Buhayrah Governorate, Egypt, which located at latitude and longitude angle of 30.07°N and 30.33°E, respectively, during winter season (2016).The experiments were evaluated the performance of solar powered pump on a drip irrigation system. The photovoltaic water pumping system performance (sun tracking orientated facing south direction and tilt angle, horizontal and 30˚, head pump, solar radiation) on the study indicator ( electric power output of panel W, panel efficiency %, discharge of pump m³/h, hydraulic power W,. The results showed that, the discharge of water pump increased from (33, 35, 36.5, 38.5 and 39.5 m³/h) with solar radiation increased from (622, 711, 740, 752 and 812 W/m²) at constant of operating water head 30m and tilt angle (30˚), the discharge of water pump increased from (32, 34, 36, 37.5 and 38 m³/h) with solar radiation increased from (243, 266, 307, 312 and 527 W/m²) at constant of operating water head 30m and horizontal plane in 17 January, 2016. When the operating water head change from (30, 35, 40, 45 to 50 m) the discharge of water pump decreased from (33, 31.5, 29, 26 to 24.5 m³/h) in 17 January, 2016. PV efficiency decreased from (18.7, 16.8, 16.2, 15.9 and 16.5%) with the temperature increased from (19, 20, 21, 23 and 25°c) with in 17 January, 2016. The hydraulic power increased from 2698 to 3229 W with the discharge increased from 33 to 39 m³/h in 17 January, 2016. This study recommended using pump powered by solar energy in drip irrigation system at the large area under the experimental conditions. | ||||
