I’ve done the math multiple times. It makes no sense in my area. I would pay more for panels then I would save in electricity. Once the panels are paid off they need to be replaced. If you don’t buy a battery you have to rely on the good will of the power company to pay fair rates for 30 years. Those rates were cut in half last year. The battery only has a 10-year life expectancy so needs to be financed over that time period or less. You’ll have to pay for removal and re-installation when your 15-year roof needs replacing. Until prices come down, it makes no sense for me.

It also depends where you got your quotes and estimates. Retail sales reps are a complete disservice to the industry, often quoting double what an installation _should_ cost. I highly recommend EnergySage for quotes. It's free and unbiased for sourcing local installers while skipping the sales reps. And do keep in mind warranties cover 90% efficiency on panels and they'll continue working beyond warranty at reduced capacity.
