Design and economic analysis of photovoltaic systems in different cities of Turkey

Abstract

In this paper, the production of electrical energy from photovoltaic systems (PV) was studied. Design, comparison, and economic analysis of the systems were performed. In order to carry out system designs and determine the technical and economical parameters of each system, HOMER program was used in the analysis. Belen (Hatay), Gelibolu (Çanakkale), Konya, Sinop, Kırklareli, and Karaman cities were selected as the design areas in Turkey. The system and levelized costs of energy were investigated for a load of 2500 kWh case annually, and the effect of capacity shortage fraction on the systems was examined. The systems were designed as grid-connected and off-grid (stand-alone) systems. Grid-connected systems were examined for cases with feed-in tariff. The levelized costs of energy vary between 0.267 and 0.367 $/kWh for PV in the case of feed-in tariff. According to the obtained results, it is determined that the grid-connected systems are more cost effective than stand-alone systems.
