If cooling the panels while generating heated water for your pool or domestic water supply were that beneficial it would have been done successfully by manufacturers years ago. The topic has been discussed here several times but all of the pros say it's not worth the effort. Even if you made such a system on your own, the complications to rig it up, install and maintain the system would make the ROI far too distant in my opinion.

Solar water heating and solar PV hybrid?
Has anyone come up with an idea or product that might use the heat on the back side of the solar panel to heat sometime of water flowing pipe to help create warm or hot water for a hot water heater? I am not sure if this would be smart or detrimental in the summer to the PV panels electrical output but people talk about cooling the panels and maybe this would do it and yet provide warm to hot water for a home? I am going to put up a south facing PV set of 14 panels at the top of my home which is a bit of square footage in my opinion that could be doing dual purpose. Any thoughts or suggestions? Links? Thank you ... I thought of a copper coil to each panel with some insulation batting and a board behind them but maybe this is too much heat for the PV panels. You could then have connectors between each one to connect them. Just my 2
