Abstract

The availability of electrical power is a major challenge for mountain climbers in maintaining communication and navigation devices during outdoor activities. This study aims to design and implement a portable solar power generation system integrated into a carrier bag as an independent energy source for hikers. A quantitative experimental method was used through system design, prototype assembly, and performance testing under various weather conditions. The system employed monocrystalline solar panels, a solar charge controller, a battery, and an inverter. Test results showed a maximum output power of 33.51 Watts under sunny and partly cloudy conditions, while the inverter maintained a stable voltage between 227–231 Volts. The system accumulated 112 Wh of daily energy and successfully powered a 250W travel kettle for ten minutes without failure. The minimum validated battery capacity of 13.3 Ah ensured stable and continuous power supply, enhancing energy self-sufficiency and supporting climber safety in outdoor environments.
