Abstract

In this research, a solar water pumping system for a 2.36-hectare grape garden in the northwest of Iran is designed and presented. Drip irrigation is used in that area to conserve water. Lorentz Compass3 was used to select a submersible water pump and then using HOMER Pro, all system's electrical components were selected. The proposed system consists of a 2kW PV, 10, 12V 105Ah batteries, and an 883W submersible pump. The designed system dynamic modeling was done in Simulink. A system controller was also designed and analyzed successfully. The simulation results show that the designed controller can maintain MPP by operating the PV array at 178.7V and at 8.3A. System economics and a method used to calculate water needs are also presented in the paper.
