@ai6yr Well we are now into our 8th year of solar having installed our system in the summer of 2014. It has saved us quite a bit however, its not as straightforward as many claim.
For sure the rebates etc which we took advantage of was our biggest reason. Why? Our city has its own utility thus electricity until 2019 was essentially locked in at $0.11 kWh. Without the rebates we may have balked at a system that would have taken us 16 years at those rates. With the rebates it was closer to 10 and while that does not seem like a lot, it made a difference in our thought process about going with solar. We may have passed had it not been for the rebates Increases the last 5 years means we broke even in 2021 ahead of schedule.
Also, the turnover for homes can be such that many simply do not bother. Or leased solar can be an issue when selling.
While dealing with our city utility was fine, you hear horror stories about PG&E etc that also make it harder to pull the trigger
