The "solar constant"... the solar power per unit area at the earth's distance from the sun ...
varies with time over a small range, because of several different influences. To answer this
question, we'll pick a reasonable average number ... 1.4 kilowatts per square meter. That
number represents total power from the sun at all wavelengths, not only visible light, arriving
at the top of the atmosphere, before any of it is absorbed by the air.
1 watt = 1 joule per second
1 hour = 3,600 seconds
1.4 kilowatts = 1,400 joules per second = (1,400 x 3,600) = 5.04 million joules per hour, per square meter
