© 2021 IEEE.In Turkey, solar power technology is quickly advancing, and investors are interested in establishing solar power plant. With the support of YEKDEM(Turkish Renewable Energy Resources Support Mechanism) and YEKA(Regulation on Renewable Energy Zones) mechanisms implemented by the state, solar investments have increased with a very serious momentum in recent years. With the recently announced YEKA GES-4 and YEKA GES-5 projects we foresee that the investments in solar power plants in Turkey will increase rapidly in the future. There is a difference in investment operation and maintenance costs, and operation efficiency of grid-tie inverter technology between string and central inverter. In this stud, we will find the optimum inverter selection by performing cost analysis and annual production with string and central inverter in 10 MW solar power plant.
