Photovoltaic modules are the most widely used around the world as a substitute for fossil fuels in producing clean and environmentally friendly solar electricity. In this study, the performance of a photovoltaic power plant established at Asmaa Bint Al-Hareth School in Sohar, Oman, was evaluated. This station can generate a power of 150 kW. The results of the study showed that the system losses fluctuate from low to high values, for example: the average daily reference return is between 4.6-7.15 (h / d), and the daily yield from 3.05-5.07 (h / d), and the system return was 11.74- 20.54 (h / d). As for the performance of the constant current, it ranged from 64% to 74%, and also in relation to the power factor, whose value ranged from 11.74% to 20.5%. The study showed that the performance of the studied station was seasonal in the sense of changing performance due to changing climate conditions, as the productivity of the station depends on the intensity of the solar radiation and the period of sunshine. The study proved that the environment conditions of the Sultanate of Oman is suitable for operating grid connected photovoltaic power stations, which is a successful option for producing electricity on the national and personal levels.
