Oman is actively reducing its dependence on non-renewable energy sources as the rest of the world transitions towards renewable energy. Oman's renewable energy sector has great promise, particularly in solar power, with several large-scale solar PV projects underway. Rooftop solar is the optimal method for Oman to attain its goals and address its current energy crisis. In this study, a solar PV grid-connected energy generation system was built and simulated using the PVSyst software. The solar photovoltaic system's technical, financial, and annual performance is also shown. The technical analysis evaluates the system's ability to perform, its effectiveness, and the anticipated amount of energy it will generate. The economic analysis encompasses the initial capital outlay, ongoing expenses, and the time required to recoup the investment. The proposed solar photovoltaic (PV) plant model produces a total power output of 4.41 kilowatts peak (KWp) in the Ibra area in the North Al-Sharqiyah region of Oman. This generated power contributes to decreased electricity expenses for both residential and business use. Furthermore, renewable solar energy is a form of environmentally friendly and sustainable energy, as it releases small amounts of carbon dioxide into the atmosphere. This proposed concept aims to promote the expansion of rooftop systems in Oman.
