On average, a 300 watt solar panel will produce about 240 watt-hours during peak sun hour (1kW/m 2 of solar radiation hitting the surface of the solar panel). And 1.2kW energy per day, considering 5 peak sun hours (5kW/m 2 solar radiation).
[pdf] A typical 300-watt solar panel is 65.8 inches long and 36.1 inches wide. It takes up 16.5 sq ft of area. If you have a 1000 sq ft roof, and you can use 75% of that roof area for solar panels, you can theoretically put 45 300-watt solar panels on a 1000 sq ft roof.
[pdf] 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.
