Abstract:

Nowadays, the growing energy demand with the advancement of technology has increased the interest in the renewable energy sources which are clean and sustainable. However the studies in the solar energy which is among the renewable energy sources has also gather speed. In this study, on grid-connected solar power plant having the power capacity of 226,4 MWe and located in Karapinar, Konya, Turkey, between northern latitudes 37 ° 45° and 37 ° 47° and eastern longitudes 33 ° 33° and 33 ° 35° was investigated. This solar power plant is composed of monocrystalline, bifacial solar panels produced with half-cut technology and a solar-tracking system on the single axis (east-west). Comparative assessments have been realized related to this solar power plant for two different months (August 2021 and January 2022) in which solar radiation intensity and ambient temperature data are both high and low. Furthermore, energy, exergy, sustainability and exergoeconomic analyses have been conducted in this plant by using daily data during 6 months. As a result of the energy and exergy analyses based on the first and second laws of thermodynamics, the energy efficiency, maximum electricity efficiency, power conversion efficiency and exergy efficiency averages of the plant were found to be 75,48%; 36,40%; 22,34%; 21,98%, respectively. The average values of the plant's sustainability index and waste exergy rate were calculated at 1,29 and 0,78, respectively. The average values of thermoeconomic and exergoeconomic parameters using the EXCEM method have been determined to be 2,43 W/$ and 2,32 W/$, respectively.
