I don't care whether you agree or not but it is a fact, not a theory. I my monitor roof temperatures continuously. Prior to the solar installations my summer roof space was 65-70C, with panels 53-58C. It makes a noticeable difference, I rarely use air conditioners.

That's good to hear. I didn't have early records so couldn't compare.
What color is your roof?

Solar is like the wind. It may be free, but putting it to work isn't!
