Solar Panels - worth it?

[Benham]

The panels come supplied with foam already stuck to the bottom of the fixing frame

Super. Thank you.

Not sure if foam between panel and roof is a good idea because panels do not operate the best if overheated. A little bit of air circulation is a good thing. That what I have. Black roof, black panel but not in contact with each other except for mounting on the edges.

It’s only under the edge on the metal cross members, which are about 1cm wide, rest of the panel has clear airflow, as air can still enter under the sides as there is a gap.

The California has a ribbed roof. The foam sits on the high ribs, plenty of air flow. My 100w panel lasted 9 yrs before failing.
