The intensity of sunlight on earth is about 100 mW/cm (that's milli-Watts per cm squared). If you had a 100% efficient solar panel that was 1m?, could you use it to light a 100W lightbulb? What if it was only 20% efficient (a bit more realistic..)? What's the total power output of the sun? The distance from the sun to earth is about 150 x 10° km.
