All around the world, the utilization of energy is drastically increasing day by day. The electricity generation using renewable energy resources has become a more authentic source to meet the needs of isolated remote areas. This article proposes an off-grid (Stand-alone) Photovoltaic (PV), Battery Energy Storage System, Diesel Generator system for electrification of residential household load in a rural area of Madurai, Tamilnadu. Hybrid Optimization Model for Electric Renewable is used to perform techno-economic analysis for designing solar PV/Battery system to meet out the requirements of load. Moreover, the obtained Total Net Present Cost (NPC) and Cost of Electricity (COE) and emissions of the proposed optimized system were significantly reduced. The configuration of the proposed system shows that solar electrical production is 68.4% and diesel emissions are 21.3%. The electricity generation using off-grid designed system cost is lower than conventional energy system. The result shows that the designed system is technically-economical and viable based on obtained NPC and COE results.
