Also.longer sunlight hours in the higher latitudes.. and the wind
here isn't easterly so panel orientation is different.
All this stuff does affect your daily amps in.
I think it has more to do with the longer daylight hours and the more direct sun angle the US gets during the summer compared to the Caribe in the winter.
Right now, we are in FL with no wind
and 95* temps. Our panels
are hotter than they ever got in the Caribe and Central America
- but we are producing 30% more daily on average here than we did there during the same month. We have 16% more daylight hours and the sun is pretty much directly overhead here now.
