Cellular base stations powered by renewable energy sources such as solar power have emerged as one of the promising solutions to these issues. This article presents an overview of the state-of-the-art in the design and deployment of solar powered cellular base stations. The power generated by solar energy is used by the DC load of the base station computer room, and the insufficient power is supplemented by energy storage. An objective of the present invention is to provide a mobile photovoltaic generation unmanned base station system for easily installing and conveniently moving the mobile base station, smoothly providing power supply even in a place difficult for the power supply, continuously supplying the power. Highjoule powers off-grid base stations with smart, stable, and green energy. By combining solar, wind, battery storage, and diesel backup, the system ensures. As Mobile Network Operators strive to increase their subscriber base, they need to address the “Bottom of the Pyramid” segment of the market and extend their footprint to very remote places in a cost-effective way.
