In this paper, we analyze long-term data of solar radiation, spanning a period of 23 years, of the town of Adrar located in the western south of Algeria to evaluate technicaleconomic feasibility of using a photovoltaic system. The aim is to answer at load demand of a typical residential house with the annual electric energy demand of 8000kWh, an average calculated according to a study made by the Algerian government and to limit carbon emissions. Simulation results using the Hybrid Optimization Model for Electric Renewable (HOMER) software is proposed. The optimization modeling demonstrates that 100% of power demand can be supplied by a PV configuration composed of 8kW PV system together with battery storage of 37.5h of autonomy. The PV penetration is 146%, the cost of generating energy from the considered PV system has been found to be 0.46 $/kWh. It is shown that with the proposed photovoltaic system, approximately 11 tons/year of the carbon emissions entering the atmosphere can be reduced for one house only.
