Abstract
Photovoltaic (PV) systems have been used globally for a long time to supply electricity for water pumping system for irrigation. System cost drops down with time since PV technology, efficiency, and design methodology have been improved and cost of wattage drops dramatically in the last decade. In the present paper optimum PV system design for water pumping system has been proposed for Oman. Intuitive and numerical methods were used to design the system. HOMER software as a numerical method was used to design the system to come up with optimum design for Oman. Also, REPS.OM software has been used to find the optimum design based on hourly meteorological data. The daily solar energy in Sohar was found to be 6.182 kWh/m2·day. However, it is found that the system annual yield factor is 2024.66 kWh/kWp. Furthermore, the capacity factor was found to be 23.05%, which is promising. The cost of energy and system capital cost has been compared with that of diesel generator and systems in literature. The comparison shows that the cost of energy is 0.180, 0.309, and 0.790 USD/kWh for PV-REPS.OM, PV-HOMER, and diesel systems, respectively, which sound that PV water pumping systems are promising in Oman.

The continuous increase in electrical global demand and concern of environment due to pollution from human kind activities leads to exploring new and clean energy technology

Regardless of the fact that hybrid systems technically and economically are effective, it is found that the proposed PV system is economical in comparison with [8] where the cost of energy is 0.200–0.580 USD/kWh, which make PV water pumping system be a good option for irrigation in rural areas of Oman
Summary
The continuous increase in electrical global demand and concern of environment due to pollution from human kind activities leads to exploring new and clean energy technology. In [3], the authors designed and investigated hybrid PV/diesel generator system using HOMER to supply village with energy consumption of 279 kWh/day, in Ethiopia. The cost of the energy was found to be 0.401 USD/kWh. In [4], the authors proposed water pumping system supplied by PV array in Algeria. In [4], the authors proposed water pumping system supplied by PV array in Algeria The cost of energy was found to be 0.170 USD/kWh. In [8], there is a comparison study of PV and diesel generator supply water pumping system for irrigation in the Northern Badia of Jordan. HOMER and REPS.OM software applications have been used for design and assessment, which contain a different system elements selection, cost of energy, and pollution
