Rated at 10.5 & produced 11.4 in 2021 and 11.8 so far this year.

In NY My telsa install of 24 panels and 2 power walls was like 36k and after tax rebates like 26k. The monthly cost of the 10 year loan + minimal electric usage is less than the pre install electric bill. I also have had zero power outages for 3 years so won't need a separate generator. It's an amazing system, zero regrets.
