Looked into this a few years ago and you could have said the same then. The problem was the deal with the financing had all these weird caveats when you looked into the details like you didn’t own the panels, and any cost would transfer with the sale of the house, it was like a forever rental with no upgrades ever.
When we get to the point that you can get solar added, and own everything, and can pay for it without financing with a positive ROI in 3 years, that’s the tipping point.
I looked at adding solar to my house 6-7 years ago and it was going to cost $60k. The return on investment would have taken 25-30 years.
What does it cost these day?
The tariffs may or may not happen, The 100% tariffs on Chinese EVs already happened in September. Joe Biden announced them in May and they kicked off already. I don’t expect Trump to change anything with that.
