Pool cooling in muggy se missouri

[PoolDoc]

The complication is calculating theoretical thermal loss through the things, because you have to consider things like panel emissivity, conductivity, and the sky's absorptivity (high on clear nights, low on cloudy humid ones).

When you've used yours for cooling have you ever compared influent and effluent temps. (If your pool is hot enough, a fever therm might work!)

Nah...I just run 'em in the cooler night air. I've forgotten what the solar panel formula is... something like your panels should have half the surface area of your pool. 'Way more than you actually need. I have the equivalent of the 3 4'x20' panels, and the "Rule" says I'm short by one...no way! Since all you are doing is warming pool water, tight tolerances on things like panel size, flow rates, critical BTU/Calories gen'd aren't really important.
