Abstract

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.

Highlights

To operate the irrigation system, we will be using solar energy which is more than enough to supply all of our electricity needs
The design of solar power system is based on the voltage and maximum current we might use for the whole system, the total power the of the system we need is multiplied by a safety factor which is approximately (1.30 – 1.5), we first choose a suitable solar panel and calculate how many in series and how many in parallel to size the array that we are building
After completing the water flow calculations for the three agricultural crops, we used one of the applications to design a solar station that depends on the location of the land to be cultivated to determine the type and number of solar panels as well as the type and capacity of the pumps used in the agricultural land

Summary

METHODOLOGY

In the problem definition section, we discussed the problem we are facing which is the shortage of water and energy sources for the Earth. The design of solar power system is based on the voltage and maximum current we might use for the whole system, the total power the of the system we need is multiplied by a safety factor which is approximately (1.30 – 1.5), we first choose a suitable solar panel and calculate how many in series and how many in parallel to size the array that we are building. After completing the water flow calculations for the three agricultural crops, we used one of the applications to design a solar station that depends on the location of the land to be cultivated to determine the type and number of solar panels as well as the type and capacity of the pumps used in the agricultural land.
