    AGP Pump Speed for Solar Panels

    I have 2 2x20' sungrabber panels and a 2 speed pump. Will I get more efficient heating with the pump on high or low?

    If the panels are cool to the touch in direct sun, you won't notice much difference. If high speed cools them better, it is more efficient from a heating perspective, but at the cost of utilizing more electricity.
