Edit: solar radiation is only 1.3kw/m2
Outside earths atmosphere. Only ~650 Watts/m^2 reach the surface of our planet.
Edit: I posted regurgitating some simplified assumption from a text book or something I must have read in the past, the 650 W/m² is wrong.


On the power outside the atmosphere I didn’t comment because I was too lazy to look it up, the and I knew the number of the previous commenter was in the ballpark.
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.
