Performance analysis of 1210kW grid-connected solar photovoltaic systems at Bukhara State University

• Analysis of Solar PV System in accordance with IEC 61724 Standard • The average performance ratio and CUF for the system are 65.15% and 11.41% • Annual average array, final and reference yields were 2.77, 2.73 and 4.64 kWh/kWp • The LCOE for the system is 0.048 USD/kWh and the simple payback period is 9.92 years • The system will save 286,856 and 989,626 tons of CO 2 for natural gas and coal Among renewable energy sources, solar energy clearly stands out due to its wide range of possibilities. Solar photovoltaic (PV) systems are widely used to generate electricity from solar energy. There are a number of standards for evaluating the efficiency of solar PV systems. In this work, the performance of a 1210 kWp solar PV system located on the roof of Bukhara State University (BukhSU) was studied based on the IEC 61724 standard. The solar PV system produced 1,209,638 kWh of electricity in 2024. The electricity generated by solar PV system is linked to solar radiation with a strong linear correlation of R 2 = 0.7406. The annual average values of array yield, final yield, and reference yield are 2.79, 2.73, and 4.64 kWh/kWp, respectively. The annual average Array losses were 1.85 kW/kWp, while the total system losses were 1.90 kWh/kWp. According to the economic analysis, the Levelised Cost of Energy is 0.048 USD/kWh and the Simple Payback Period is 9.92 years. The average Capacity Utilization Factor and Performance Ratio of the system are 11.41% and 65.15%. The system saves 286,856 tons and 989,626 tons of CO 2 compared to natural gas and coal.
