Performance Analysis and Comparison of Performance Ratio of Solar Power Plant

Abstract

Significant advancements have been made in the field of renewable energy worldwide. In light of these improvements, renewable energy will meet a substantial part of Türkiye’s energy needs in the future. Solar energy is abundantly present in many parts of the country, and grid-connected solar photovoltaic (SPV) power plants are gaining increasing importance. In the present study, the performance analysis of a 250 kWp solar power plant built at the Dicle University was performed in accordance with the performance criteria in the standard IEC 61724. Final yield, reference yield, and performance ratio were detected to vary from 1.94 to 5.98 kWh/kWp-day, 2.1 to 8.88 kWh/kWp-day, and 58 to 99%, respectively. The average annual performance ratio, capacity factor, and system efficiency were observed to be 83%, 1.23%, and 97.6%, respectively. This study also presents the calculated performance parameters along with such values as energy generation, global radiation, temperature, wind, and sunshine duration of the period concerned. The results presented provide insight into the longterm performance of the solar power plant under actual working conditions in Türkiye. The obtained results were also compared with the performance ratios of solar power plants (SPP) in other countries as reported in the literature. Thus, the performance ratios of SPP in different countries were comparatively assessed.
