DESIGN AND EVALUATION OF SOLAR ENERGYPOWERD GROUNDWATER PUMPING SYSTEM FOR IRRIGATION FARM IN DESERT

In this study investigates the design of a solar-powered groundwater pumping system to irrigate desert lands in Najaf, Iraq. The water pumping rate was calculated for the land to be cultivated, which is 83.4 m³ / day. We designed an irrigation system for the three agricultural crops that depend on soil and water sensors in their work. Where a land area of 12500 m² was fed with water through two well pumps pumps (5.5 KW) and a tank (0.78 KW), the number of panels required to operate the irrigation system was 27 monocrystalline solar panels of N type 390 W. Matlab/Simulink and the theoretical results showed that the system can irrigate these lands, thus reducing the waste of electrical energy for the panels, and the purity of the water and air which gives us a green and beautiful space
