Air source heat pumps are pretty cheap and work well to low temps now. You might still need the grid, but can net-out over the year.

- PaulDavisThe1st 5y agoYeah, as I just mentioned adjacent to this, our 6.6kW array produces 1/3 of what we need during the winter, but 3x what we need in the summer. Last year (the first full year), we generated 93% of our electricity use over the full year. We heat solely with air source heat pumps.
