In this study, the 18 techno-economic evaluation for two hybrid renewable energy systems is carried out to achieve 19 this target for Bandar Dayyer. In this regard, using the Homer software, the total amount of 20 electricity production by these systems are equal to 470176 kW, of which, 22409 kW is 21 provided by and PV-Generic system and 447767 kW by PV-diesel-Generic system. According 22 to the results of this analysis, it should be mentioned that this area has an appropriate potential 23 of wind speed and solar radiation; which means that it can be suitable for investment on the 24 renewable energy site for electrical production. 25 26 Keywords: Renewable energy system; HOMER software; Solar energy; Wind energy. 27 28 Introduction 29 Adequate provision of energy has always been a crucial issue and is deemed as one of the best 30 measures for estimating the economic growth and development of a country. In recent decades, 31 increasing CO2 emission into the atmosphere is considered as one of the main reasons for global 32 warming with adverse environmental effects such as sea level rise, floods, droughts, etc. 33 Reduction of fossil fuels consumption by energy efficiency, carbon capture, and storage, 34 conversion of CO2 to different products, application of renewable energies and reforestation 35
