Best Answer

The Solar Constant refers to how much energy Earth gets from the Sun, per square meter (or another convenient unit of area). It is approximately 1.3-1.4 kW/m2 at the top of the atmosphere; the amount that reaches the surface is perhaps 2/3 of that value under ideal conditions - for example, no clouds.
