Outside earths atmosphere. Only ~650 Watts/m^2 reach the surface of our planet.

No that’s not right, it’s about 1000 watts/m2 on the surface. But it is on a totally clear day with the sun directly overhead. So depending on your latitude you get less per m2 because the Earth is round.

On the power outside the atmosphere I didn’t comment because I was too lazy to look it up, the ballpark of the previous commenter was correct.
Regarding the surface: my apologies, I quoted a number from university that must have been a simplification for a calculation exercise, and I made the mistake of never thinking about it critically. Turns out I was wrong.
