In this study, Matlab/Simulink software was used to create a smart irrigation system that utilizes the electricity produced by photovoltaic cells. The system setup will be carried out considering that the farm needs 90,000 liters of water during its periodic irrigation period. The designed irrigation system will be installed in the rural area of Mosul, Iraq. According to our calculations, a submersible pump compatible with a 1400 W power BLDC model and capable of a 200 m water lifting height is sufficient. It has been observed that using a smart irrigation system is more efficient and economical compared to traditional irrigation systems. Approximately 36% savings were achieved from the design of the 1400 W power BLDC model submersible pump and about 67% savings from the design of the photovoltaic array. Due to its location, Iraq is one of the countries with high annual solar radiation values. We believe that using smart irrigation system models in regions with high electricity energy needs but low coverage rates will contribute positively to national economies.
