Aren't they all sunny at the top of the atmosphere?
> gives about 1360 watts per square meter
I assume that's very much latitude dependent

There’s also more atmosphere in the way the further you go from the equator which will affect how much solar radiation reaches the earth. Overall only about half of solar radiation reaches the surface.
