Integrating Digital Technology in the Study of Rooftop Solar Panel Planning for Hospital By Using Software

Abstract

Electric energy is a vital need in daily life. Solar panel is a renewable energy technology that converts direct sunlight into electricity. Hospital has high electricity demand, especially in special rooms such as the emergency room, operating rooms, and inpatient rooms. This study aims to design a rooftop solar panel system for hospital. The design was carried out manually and simulated using integrating digital technology and simulator of software. This solar panel system uses capacity of 550 WP. Using inverter and batteries. The simulation results show that the energy produced by the solar panel reaches 16,375.05 kWh per year. The maximum efficiency of the solar panel will increase if the angle when the sun is shining is always at 90º and the angle of the sun's declination is about 74.99° and after knowing the value of α, the angle of inclination of the solar panel can be found using the formula is about 15.01° facing northeast because the location is south of the equator. With these results, the off-grid solar panel design at hospital is considered feasible for implementation.
