Yeah, 2021's freeze was the final straw for me. Our grid sucks, and solar/batteries are relatively inexpensive in terms of prices through Austin Energy, so there was no upside to remaining on the grid.
I was paying ~$1,000 per year in a 1/1 for what was usually 30kWh/month and often lower. 600Ah of LFP ran $1,700, 1200W of A-grade 9BB panels were $900, and a hybrid inverter was $600, all at 0% interest.
So recoup time is roughly three years, except I'm not at the whims of ERCOT. Between that and switching to 5G internet, grid failures simply don't affect me. I read about them on Reddit and have the "Oh, no! Anyway ..." meme reaction.
