I have (6) 2 x 20 Sungrabber solar panels for my 18 x 36 inground pool.
I run an independent 3/4 hp pump for the solar system and wondering about efficiency
of the panels. Should I be installing a diverting valve to reduce flow through the panels?
I think this is getting into the "Law of diminishing returns" area, but wondering how to maximize
the heat output.
I guess I would need to figure out my GPM output?
Who can help here?
