The primary objective of this study is to determine the optimum hybrid system able to supply the necessary electrical load of a typical community in a remote location in Greece. The renewable energy systems were comprised of different combinations of PV modules and wind turbines supplemented with battery storage. A software tool, HOMER is used for the analysis. The hybrid system analysis has showed that the minimum cost of energy is 0.268 $/kWh with 10% annual capacity of shortage. The optimum hybrid system is comprised of 1.5 kW PV array, 1 wind generator, 3 kW power converter and 14 storage batteries.
