Özet

This study presents the energy, exergy, sustainability and exergoeconomic analysis of a grid-connected solar power plant with a power capacity of 226.4 MWe with a single axis solar tracking system consisting of monocrystalline and bifacial solar panels manufactured with half-cut technology. This solar power plant is located in KarapInar district of Konya province in Türkiye, between 37 45 and 37 47 north latitudes and 33 33 and 33 35 east longitudes. Based on the first and second laws of thermodynamics, the 6-month average values of the energy efficiency, maximum electrical efficiency, power conversion efficiency, exergy efficiency, sustainability index, thermoeconomic, and exergoeconomic parameters of the power plant were evaluated in detail. As a result of the energy and exergy analyses, the energy efficiency, maximum electricity efficiency, power conversion efficiency, and exergy efficiency of the plant were found to be 75.50%, 36.42%, 22.34%, and 21.98%, respectively. The sustainability index of the power plant is 1.29. Thermoeconomic and exergoeconomic parameter values were calculated as 2.43 W/$ and 2.32 W/$, respectively, using EXCEM method.
