Southern Europe, so basically dead center in the US.
I've edited the post because I accidentally cropped it off, good catch!

Basically doesn't matter as long your not in Antarctica or death valley. They give you a 25 year warranty in all of Europe or the US and even after that it's not broken, just less efficient. I'll see if I can find a study that has this in relation to climate.

See this link for a solar irradiation map so you can estimate the energy breakeven at other locations (keep in mind this is not money breakeven!)
