Smart Standalone PV-Based Street Lighting for Rural Areas in Wonogiri Regency

Solar energy is an abundant and free source of sustainable energy. The objective of this project was to construct and examine smart, standalone photovoltaic (PV) street lighting in Kepyar Village, a rural community located in Wonogiri Regency, Central Java. The intelligent, standalone PV-based lighting system consisted of a 5-meter streetlight pole outfitted with a 60 Wp monocrystalline solar panel system and an Internet of Things (IoT) system. In 2024, measurements were taken in August and September. The system was able to capture energy from sunlight from 6 a.m. until 5 p.m. The average amount of daily energy stored was 144 and 148 Wh, respectively, allowing it to power the street lights for around 7 hours. The findings also revealed that installing standalone PV-based street lighting can provide significant community advantages.
