There must be some kind of calculation generally based on latitude?

A sub-question that I would be curious about is how much climate in that region then affects the total possible solar energy. How much is the variance from a naive calculation just based on latitude?

One other second-order effect is: developed economies are heavily weighted towards places that are cold / farther north than less developed places (as a very general rule). And, a lot of people don't realize how much less energy efficient it is per-capita to make a space human comfortable year round in a "cold" climate vs a warm one.

-That's a new way of comparing economies where the price and stability of energy is better in a warm, more equator proximate location.
