You'd better get a small generator for extra juice because that solar panel will not be enough to keep a battery charged when you're drawing juice for a furnace motor, etc. It's worse on a Fall or early winter hunt when there may be little sunshine for the panel. I'm out west for anywhere from 5 to 11 weeks every Fall in my trailer and I figure a gallon of gas a day for the generator to keep everything in the trailer operational, including the micro.
