Abstract: This paper presents the design, solar sizing, and technical verification of the Green EcoCharge (GEC) Kiosk designed for Kampung Orang Asli Tewowoh, a remote rural village in Mersing, Johor, Malaysia. The GEC Kiosk was envisioned to combat the pressing issues of limited access to electricity by implementing a standalone solar-powered mobile charging kiosk with an integrated IoT-based monitoring system. The approach encompasses thorough load analysis, system design, and power calculation grounded in real-world usage patterns. The community’s energy requirement was approximated at 4,696 Wh/day, with a supply setup of 600W solar panel and 2,400Wh battery bank capacity, which is capable of powering mobile phones, laptops, and onboard electronics of the kiosk. The effectiveness of the system is substantiated by its capability to address the daily charging needs of up to 60 mobile phones and 8 laptops, while an integrated IoT system, based on ESP32 and Blynk platform, facilitates real-time performance monitoring and diagnostics. The system also exhibits efficient energy management and sustainability with 246 Wh of excess energy during normal operation. Aside from technical deliverables, the kiosk also aids in enhanced digital connectivity, access to education, and socio-economic empowerment of the Orang Asli people. The GEC Kiosk concept offers a replicable and scalable model in support of Sustainable Development Goal (SDG) 7, granting clean and reliable energy for marginalized rural communities.
