I recommend watching a video one of the biggest tech reviewers did about the first year with his Tesla Solar Tile+Battery setup.
The TLDR- lives in NJ which has net metering. Spent ~$120k on the setup, got ~$28k in tax credits, so he paid a little over $90k for a 29 Kw array and 3 power wall batteries that can store 40.5 Kwh.
He used ~54Mwh of power in a year that cost ~$9600 if it all came from the grid (including an electric car, so charging at home), so the payback is between 9-10 years. He didn’t pay for any electricity from the grid for the whole year because of all the excess he sold back in the fall/spring.
Solar isn’t as good of a deal in GA because our net metering isn’t a 1 to 1 swap. If you sell excess power to the grid, GA Power pays you the wholesale price they would pay to other providers instead of just crediting you with the amount sent back. You are better off having a bigger battery system to store all the power you capture because the economics are more favorable never using power from the grid compared to selling excess.
