This study presents an optimal configuration of a hybrid renewable energy source with a wind turbine and a photovoltaic system to fulfill the required electricity power of a medium-size workshop in an industrial area in Ardabil, Iran. The paper presents a techno-economic analysis for achieving the least-cost configuration using historic data from supply and demand sides. The results show that due to the windy climatic conditions in the studied area, a large percentage of the generated energy is supplied by wind energy resources. Eight feasible configurations including Diesel, Diesel/Battery, PV/Diesel /Battery, Wind/Diesel/Battery, PV/Wind/Diesel/Battery, PV/Diesel, Wind/Diesel, and PV/Wind/ Diesel are considered in hourly-based simulations. Energy cost is calculated for different conditions. The results show that the integration of 13 kW diesel generator, 1 kW PV array, 2 numbers of 3kW wind turbine, 6.13 kW converter and 27 strings of 1 kW lead-acid batteries storage bank is the best configuration that leads to the minimum Levelized Cost of Energy (COE) of 0.462 $/kWh in Ardabil area. The simple payback for the proposed system is obtained 7.17 years and the discount payback is achieved 9.78 years and finally, the lifetime for the optimum system is obtained 20 years which shows the feasibility and effectiveness of the implemented system for the studied workshop.
