Experimental investigation of a mobile pv water pumping system

Abstract EN

Solar water pumping system has several advantages as alternative energy source of energy instead of diesel and electric generators.

it is eco-friendly, simple, easy to install, and available in each site location.

the main components of the PV water pumping system are PV modules, inverter, control, metallic structure, and submersible or surface water pump.

the main parameters affecting the performance of the solar water pumping system are the PV module tilt angle and orientation as they affect the solar radiation falling, electric power output and amount of daily water produced.

the experimental work is designed, installed and tested in the solar energy department, engineering and renewable energy research institute, national research Centre, Dokki, Giza, Egypt.

in the current study the system performance in the four seasons at different tilt angle and orientations is evaluated.

the solar radiation falling on the PV modules and the electric power produced are measured for different tilt angles and orientations in the four seasons.

also the daily water produced for different tilt angles and orientations in the four seasons is estimated.

it is found that for south facing and tilt angles 0, 10, 40, and 80, the maximum value of daily water produced is occured in summer while the minimum value is occoured in winter.

it is found also that the daily water produced, m3 is affected by both tilt angles and azimuth angles in each seasons, the maximum value of the daily water produced, m3 in summer with tilt angle equal 10 and azimuth angle equal 0 while the maximum value attained in winter with tilt angle equal 60 and azimuth angle equal 0.

the maximum value of summer, autumn, winter, and spring were 32 m3, 27.25 m3, 27.25 m3, 27.50 m3 for south facing and tilt angles 10, 40, 60, 40 respectively.
