Desain Sistem Penerangan Jalan Berbasis Energi Surya Di Fakultas Teknik Universitas Riau
ABSTRACT
Solar-powered street lighting offers an energy-efficient and environmentally friendly solution that aligns with the green campus concept. This study aims to design a solar-powered street lighting system for the Faculty of Engineering at the University of Riau, considering both technical and economic aspects. The technical analysis was conducted through energy requirement calculations and lighting simulations using DIALux Evo software, in accordance with the SNI 7391:2008 standard. The simulation results indicate that a pole height of 7 meters and an inter-pole spacing of 21 meters produce an average illuminance of 4.76 lux with a uniformity value (g₁) of 0.2. After accounting for 24% system power losses, the daily energy requirement increased to 260.55 Wh, resulting in a battery capacity of 25.44 Ah and a solar panel capacity of 56.85 Wp. From an economic standpoint, the separated system configuration yields a total cost of Rp292,995,552. In contrast, the All-in-One system offers the lowest total cost of Rp266,400,000 compared to the conventional system’s Rp299,518,260 over 20 years. Compared to previous studies, this research demonstrates an advantage by integrating both technical and economic analyses simultaneously, an approach that is rarely applied in campus-scale solar-powered street lighting studies.
