During the last 20 years, I've noticed a lot of non-functioning solar hot water panels in the local area.
Slowly over time, the collectors have been removed and re-shingling was done.
Some of the panels weren't very well made and were really dilapidated.

One problem with those older system was over-heating in the collectors,
whenever there was a pump failure etc.
The panels would really boil during a power loss. Any materials that couldn't hold up to the high temps got degraded.

I think they used to call it, 'solar collector stagnation'..
