The use of solar energy, which is one of the renewable energy sources, is increasing every year. And the installed capacity of solar plants is also increasing all over the world. This shows that the transition to green energy is accelerating. It will be beneficial to monitor the useful working capacities of such solar plants installed in the world, and in our country, the amount of energy produced, and the performance of months and seasons. In the article, the annual amount of energy produced by an on-grid solar plant with a capacity of 200.75kW is equal to 198.32MWh, and calculations give the payback period is 5.6 years. The maximum value of the installed capacity utilization coefficient was 19.57% in June, the minimum value was 5.41% in January, and the average annual value was 11.25%. In addition, the specific energy coefficient peaked at 4.7 kWh/kW in June. During the winter months, it reached its lowest values, with 1.53 kWh/kW in December, 1.3 kWh/kW in January, and 1.54 kWh/kW in February.
