Recently was given a set of 4 year old solar direct Vortex panels from a friend that no longer wanted them after getting a new roof. They look in good shape and I plan on installing them on my house soon.
The panels were previously installed with thin, corrugated fiberglass sheets under each solar collector. My friend says he had the system installed professionally. However, I believe he previously had the Fafco panels and these may have been a holdover from those. The Vortex installation manual makes no mention of putting anything under the panels. I have the sheets, so question is, should I use them?
Thanks!
