The rising energy demands and escalating electricity bill in one of manufacturing industry, in Batam have underscored the need for sustainable and cost-effective energy alternatives. In response to these challenges, this research aimed to evaluate technical and economic feasibility of integrating a Solar Photovoltaic (PV) system into the facility's energy supply. This study employed PVSyst software to simulate the system's technical performance, focusing on variables such as energy yield, capacity factor, and performance ratio. Energy yield was calculated based on total energy output, capacity factor as ratio of actual to potential maximum energy production, and performance ratio as efficiency of the system under real conditions compared to standard test conditions. Economic feasibility was determined using financial metrics, including Benefit-Cost Ratio (BCR), Internal Rate of Return (IRR), and Levelized Cost of Electricity (LCOE). BCR was calculated by comparing present value of benefits to costs, IRR by identifying discount rate that equates the net present value to zero, and LCOE by dividing total life-cycle costs by the total energy output. The analysis revealed that the system, comprising 174 PV panels with a capacity of 94.527 kWp, could generate 1.048199 MWh annually. The economic evaluation indicated a BCR of 1.622, an IRR of 11.4%, and an LCOE of Rp 991.18 per kW $h$, affirming the system's technical and economic viability. These findings suggest that solar PV systems can significantly reduce energy costs and promote sustainability in industrial operations, supporting the broader adoption of renewable energy in the manufacturing sector. © 2024 IEEE.
