@xkcdbot Single panel comic.
Option A: a solar panel 1 meter square on a house's roof labeled south facing. Math underneath: $0.20 per kWh times 4 kWh per meter square per day times 1 meter square times 20% equals $58 per year
Option B: the same solar panel on the surface of the sun labeled downward. Math underneath: $0.20 per kWh times sun luminosity divided by the sun area times 1 meter square times 20% equals $22 million per year
