Water Temp

[WagonPilot]

A solar panel works EXACTLY like your car radiator works, only backwards. Your radiator takes the hot water from the engine and exposes it to cool air, cooling the water and keeping the engine from melting. So if you run your solar panel at night, when it's cool, it will cool your pool (if the pool's too warm) in EXACTLY the same way.

Not to pick a nit, but it's not EXACTLY the same. The car radiator (dispite its name) is actually utilizing convective heat transfer, while running the solar panels at night is primarily a blackbody radiation transfer.

Yup, that's a nit. The car radiator uses radiation--and the fan moves it away when the car is idling.

Still, it DOES function at night in a similar fashion...
