Cost of PV electricity - Case study of Greece

► We examine the potential for a 20 kW PV array for the 46 considered sites in Greece. ► The energy produced each year from the PV array was varied between 33.35 and 41.63 MW h. ► The cost of electricity varies between 0.122 and 0.152 €/kW h. ► Considerable quantity of CO2 can be avoided entering into the atmosphere each year. ► The PV expected to play an important role in the future energy generation in Greece.
