Development and Performance Evaluation of a Mobile Solar Generator

Abstract

This study aims to develop a mobile solar generator using the analysis, design, development, implementation, testing, and evaluation (ADDIE) development model. The Mobile Solar Generator (MSG) was created to offer a backup source of electricity for homes, businesses, and schools, especially during power outages caused by natural disasters. It uses both solar power technology and the idea of a conventional AC generator. The MSG comprises two 250 ampere-hour, 12-volt gel-type deep cycle batteries; a 3-kilowatt inverter; a 40-ampere solar charge controller; and four 330-watt monocrystalline photovoltaic panels affixed to the roof of the minibus. The performance testing concentrated on component voltage, battery voltage, charging current, charging capacity, and abnormality codes. The findings showed that charging is feasible between 7:00 AM and 5:00 PM and best between 8:30 AM and 3:30 PM during sunny weather. The charging capacity was best during sunny weather without load (SWOL) conditions, with 210.5 ampere-hours on average. Discharging time with load was longer during sunny weather, and charging during cloudy weather is still feasible. The payback period for this system is estimated to be twenty-five (25) months.
