One square mile on the surface receives 2.5 Gigawatts of solar energy. That’s Gigawatts with a “G”. It’s ~30% higher in space. The Starlink global satellite network is entirely solar/battery powered. 6), a reasonable rule of thumb is 3GWh of energy per square mile per day. Easy math, but almost no one does these basic calculations.
Factoring in solar panel efficiency (25%), packing density (80%) and usable daylight hours (
