Abstract

The Turkish Republic of Northern Cyprus is located in a region rich in solar energy potential, one of the renewable energy sources. Exergonomic analyzes have been carried out in recent years to determine to what extent electricity generation facilities reflect their potential. These studies, also called exergy analysis, include a series of calculations and analyzes aimed at revealing the potential that a power plant should reflect. In this study, exergy analysis of solar power plants belonging to Cyprus International University was carried out and the condition of the plants was analyzed. As a result of the analysis, it was determined that the energy efficiency of the system was 93% and the daily electricity efficiency was 12%. This value shows that the system has a good level of efficiency, considering the average efficiency of photovoltaic panels. As a result of our exergy analysis, the exergy efficiency of our system was found to be around 73%. According to this value, a large part of the usable energy is lost in our system. In order to increase these values, all universally derived methods must be reviewed and the appropriate ones must be included in the system. In this way, it is aimed to prevent global climate imbalances by increasing the amount of energy obtained from renewable energy sources in energy production, first at the Cyprus International University and then in the Turkish Republic of Northern Cyprus.
