Exergoeconomic Analysis of a Solar Photovoltaic Module in Karabük, Turkey

This paper deals with the exergoeconomic analysis of a 130 Watt-peak (Wp) solar photovoltaic (PV) panel that is constructed at the top of Engineering Faculty of Karabuk University (41.12 N, 32.39 W) in Karabuk province, Turkey. It is known that seasonal differences cause a variation in the exergoeconomic parameters (energy and exergy loss rates) of solar PV systems. Due to this perspective, for regional climatic parameters four days in November are selected. Within this research, first the exergy analysis is performed on the system and then the economic values of the results are evaluated using the exergy, cost, energy, and mass method. The energy efficiency of the considered system in November varies between 9,6% and 17,1%, respectively. Additionally, the exergy efficiency of the system in November varies between 9,2% and 15,8% respectively. The average unit cost of the exergy values for November are calculated based on the model as 0.191 W/$ and 0.392 W/$ which are the minimum and maximum rates, respectively. Moreover, the average unit cost of the energy values for selected days are estimated as 0.175 W/$ and 0.326 W/$, respectively.
