I thought Winters in Alaska had very little Sun?? I was in Anchorage one time and YES it was very COLD but we literally had 45 minutes of daylight ... well maybe a few minutes more ... but we all know what you are saying ... The colder it is the more amps the panels cranks out ...
Here in Finland (63 degrees North, higher up than Anchorage) we only get up to 4 hours max of sunlight in dead of Winter on a cold clear day, however taking the reflection on the snow in mind and the higher performance for solar panels in cold temperatures, this amounts to quite a bit of power.
