Design and Analysis of a PV system for irrigation of a ten Hectare farm in Pakistan

Farmers in Pakistan are very intent in solar pumps because of the lack of utility power. Photovoltaic panels are in widespread use worldwide for a reliable low-cost electricity generation for irrigation. When properly designed, a PV water pumping system can result in notable long-term cost. In this paper using actual farm data, the design of a stand-alone PV water pumping system has been completed using HOMER Pro. The designed system consists of 78 PV panels with 60 batteries and a 20.7 kW inverter for the pump. The system analysis shows that such a system can meet the watering needs of that farm throughout the year for all type of crops. The dynamic model of the designed system has been simulated in MATLAB/Simulink. Perturbation and the observation-based algorithm has been used for maximum power extraction from PV. Simulation results show that the system can provide a stable voltage and frequency. This research also provides a relative study among all alternative systems economically
