I was thinking of industrial installations, but similar issue with residential. I assume that not many roofs are good after 20-30 years, so by the time the solar panel warranty starts to expire, it is time to get a new roof. Might as well upgrade panels at the same time.

Ah, sure. Yes, similar math. I forgot that for residential, in many areas the replacement panels would probably come about like a typical roof replacement: after a storm, subsidized by insurance. That may be the case with industrial/commercial as well, but I’m not familiar with insurance trends there.
