I got solar in northern California with new roof that needed to be replaced. I got 30 percent tax credit on the roof as well. Paid for the roof in cash but took 10 year loan out for the solar panels at 3.0 percent. Break even at this rate is about 4 years already a few year in. With inflation right now I feel like I got good deal borrowing the money. Right now my loan payment plus then 10.00 monthly connection fee is less than my average monthly bill before 2019. Not sure I would do it with needing a new roof though. But everybody experience will be different.

You do, but it seems pretty good even taking into account opportunity cost? My calculations: https://news.ycombinator.com/item?id=31105389

Someone else said it better in a different subthread: https://news.ycombinator.com/item?id=31105120

Yah I’m not doubting it is good in Cali, I’m just saying you need to include the opportunity cost if going that route.

I wish the break even was better further north for me.
