We recently spent $30,000 to re-roof our house (it’s a large,complicated roofing job - we had two estimates that were $60K+). The contract for the roofing job had a clause that installing solar panels voids the warranty. So even if the panels were cost effective (which they’re not), I’m not letting some poorly trained installer put holes in my roof.
Yup, the only way to have solar is at ground level, where you can get at the things to clean and service them. These guys ruin almost all the roofs they install panels on. Then they go out of business.

That’s a concern for me also ,, I wouldn’t do it unless I was re-roofing in metal (special attachment hardware that doesn’t penetrate the roof system is available) or if I placed panels on a unattached garage or similar roof structure.
