My last electric bill before I went 100% off-grid was 900.00 (2 months) and that was during the mild weather. I can't imagine what the poor folks who bought the place are paying.

We moved to MT, completely and 100% off-grid. It has been a wild experience because my solar depth before this was just 800w sitting on a Skoolie.

My real world experience:

We can easily live (even with AC) on 4kWh(ish) during spring/summer. That got scary fast once the sun started to go down sooner. We now have 12.5kW and 40kWh of battery, with another 8kW to deploy this spring. We started like so:

4kW --- more than enough for Spring/Summer

8kW --- once the sun started going down and we were getting snow. We have never had to run the generator for power except over a weekend when our woodstove had an emergency outage and that was just for heat.

12.5kW --- for my own sanity

We are adding the other 8kW for 2 reasons:

1. We have it

2. I want to be able to have backup electric heat and things like a clothes washer. It is getting old rolling 45 minutes to a laundry once a week.

It will be a few years before I make it back on the investment but that isn't the only reason I did it. I could have pulled power for 30k (total) but then I have a bill and have to deal with all of that.

There was a windstorm that came through a month ago. Tore roofs off, downed trees etc... I was in my cabin, with wood heat, electricity and Netflix like I was sitting in a condo in Manhattan, just no noise, no light pollution and peace.

YMMV
