Abstract: In this study, an exergoeconomic analysis was conducted for a grid-connected photovoltaic system with a nominal power of 1,166 kWp to be installed in all provinces of Turkey. First, energy input, exergy input and electricity generation of the system were calculated depending on the hourly climatic condition of each province. Next, annual energy and exergy efficiencies of the system were determined. Last, unit electricity generation costs were obtained with exergoeconomic analysis by using SPECO method. All annual results were presented in maps. The minimum electricity generation cost was determined as 31 USD/MWh in Niğde, while maximum electricity generation cost was in Giresun as 54 USD/MWh. The maximum energy and exergy efficiencies were determined as 17.4%-18.7% in Kars, as one of the coldest provinces; the lowest energy and exergy efficiencies were determined as 16.4%-17.6% in Şanlıurfa, as one of the warmest provinces, respectively.

Keywords: solar energy; photovoltaic system; energy and exergy efficiencies; exergoeconomic analysis; electricity generation cost; mapping; Turkey.
