Abstract | Small businesses, particularly those operating in the informal sector, often face significant challenges in accessing reliable and affordable energy. Mobile vendors, such as street food vendors and market stallholders, are particularly vulnerable to energy insecurity, This study addressed persistent energy insecurity among mobile vendors in informal markets, exemplified by Cebu City's Carbon Night Market, where reliance on conventional, often insufficient, power sources hinders basic needs like lighting, charging, and ventilation. Utilizing the ADDIE model, a Solar-Powered Prepaid Portable Electrical Energy Vending Machine (SPPEEVM) was developed. This innovative system integrates a 200W solar panel, 200Ah LiFePO4 batteries, a 1500W inverter, and a Raspberry Pi/Arduino control system to power up to four vendors simultaneously. Evaluation using the DOST Technology Assessment Protocol (TAP-TEEPS) revealed high technical, economic, environmental, political, and social feasibility. While broadly accepted, especially by younger female vendors, older participants and vendors showed slightly lower conformity ratings. The findings underscore the critical need for alternative energy solutions for mobile vendors, demonstrating the SPPEEVM as a viable, sustainable, and capable option, providing continuous power for 5-6 hours. |
