Design Simulation of a Rooftop Solar Power System Using PVSyst for Eco-Friendly Energy Supply at Hospital

Abstrak

Solar energy is one of the most promising renewable energy sources and has the highest potential among other alternatives to address global energy challenges while maintaining environmental sustainability. This study presents the design of a rooftop photovoltaic (PV) system at the Hospital Distribution Substation using the PVSyst software. The proposed system aims to supply electrical energy for existing substation equipment, including 20 KV cubicles, RTU, LED lighting, and power outlets. The design employs a 5.339 kWp PV array covering an area of 26 m², integrated with a Generic 3 kW Hybrid Solar Inverter to ensure stable and efficient power conversion. Simulation results using PVSyst indicate that the proposed system can generate an average of 18.398 kWh per day, demonstrating adequate energy yield and reliability under local solar irradiance conditions. The findings emphasize the potential of small-scale hybrid PV systems to enhance energy independence, operational reliability, and carbon reduction in public service institutions such as hospitals.
