You asked what size solar system you would need in the Tuscan area. 7K would suffice. Then you'll need 2 batteries.....ugh. That solar will cost you about $15,000. The batteries another $10,000. No way I would leave that stuff sitting unattended for a long period out in the middle of nowhere. Diesel generators are a better bet than a propane generator. They use less fuel and last a whole lot longer. You'll have acreage, so, you could put it far enough away that the noise would not bother you. I just read about wells drying up all around the Tuscan area. If you made your system large enough, you could lease out spaces to Snow Birds, and use that money to put an even larger system in?
