Wind map for Fairbanks

Doesn't look fantastic, but there is still wind. Most of the map are for large utility windmills, which is a very different ROI.

I'm suprised, you get an average of 3.99 hours per day. However your range is greater then for me in MA. Ergo you need to compensate for that with either more batteries, utility power or a generator. Would it be that bad to run the generator for an hour a day to charge up your batteries?
