The communication base station installs solar panels outdoors, and adds MPPT solar controllers and other equipment in the computer room. 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 devices.
[pdf] Communications companies can reduce dependency on the grid and assure a better and more stabilized power supply with the installation of photovoltaic and solar equipment. That independence is very critical in keeping communications reliable, mainly in rural and off-grid areas.
