How about running water through the back side of the panels to keep them cool, transfer the heat into a heat battery (sand) then us that to assist your hot water heater.
Right on. and PV get’s less efficient when it gets hot, I’m unsure if there’s enough waste heat to do anything useful. but there is at least a marginally good reason to cool them.

Either that or use it for temperature differential power generation.
Although I guess you could use the power generated by the panels to run a heat pump to boil the water used for cooling too.
