This paper presents an analysis and development of a 22 MW photovoltaic solar power plant at Rustaq-Juma, Sultanate of Oman, using a convective procedure and PV-SYST software. The location was chosen due to its high annual solar irradiance, with the proposed plant expected to produce 38.009 GWh of energy annually, providing electricity to approximately 1,466 homes and reducing carbon emissions by 15,900 tons. The grid-connected PV solar plant is assessed as technically, environmentally, and economically feasible, with a Levelized Cost of Electricity of $0.06/kWh, a discounted payback period of 11 years, and a net present value of $13 million.
