Prototype development of a solar-powered backpack for camping applications

Abstract

Solar energy, the use and importance of which is increasing day by day, stands out among renewable energy sources with many applications. In this study, the application of solar powered orthopedic back support backpack is presented with a unique photovoltaic module structure. The 2x12W photovoltaic panel system is mounted on the backpack with a rail arrangement and optional use is provided according to the user's preference. Since there will be additional equipment in the solar self-energized backpack compared to a normal bag, the sections where the items should be put in the bag according to their weight are specified to the user. Considering the center of gravity of the backpack, pockets are made in the parts where heavy components will be fixed, and a 12V 7Ah lead acid battery is mounted in this section. There is a 5V - 1A USB output at the system output and a modified sinus inverter for AC loads. In addition, prototype production was carried out for the realized design, and an attractive product was created for camping applications where mobile phones can be charged and simple AC loads can be fed, and for travellers traveling by hitchhiking method.
