We had some acres up on the mountain where we kept a 34' 5th wheel as our "cabin in the mountains". One Kyocera 120 watt solar panel provided us with fully charged RV batteries whenever we needed them, only time we ran a generator is when the cook wanted to use the microwave or to run the vacuum cleaner. Worked for us for 28 years. Nice thing about solar panels is there are no moving parts to wear out or need lubrication and maintenance.
Our neighbor up the hill from us has a full solar home, completely off the grid, 8 solar panels, big bank of batteries, propane fired generator for emergencies. They live in comfort.
I'm pretty close to the same scenario with my cabin in Montana. I have a small solar system (100 watt) with batteries and that keeps me going for all of my admittedly modest needs. I don't have a fridge or air conditioning, just a few lights, a fan and then all the battery operated stuff, from drills to phones. For heating I use the local trees and if there's ever something that needs more juice I have a propane/gas generator (rarely use it other than to keep it in good operating condition). My brother has a similar setup on his little ranch in Alabama, and he uses air conditioning all the time, which isn't a problem with the size of his solar system.
This is done out of necessity, though, since I don't have power lines anywhere near my cabin. It'd be a lot nicer if all I had to do was flip a switch.
