homemade solar panels

[kbalch]

Those sort of radiant heat solar panels are commonly used here in central Florida for pool heating. The panels are generally mounted on the roof facing the prevailing sun, water is circulated through them by means of a pump, and returned directly to the pool.

I've never had that sort of setup on any of my pools, but they're fairly common so they must work, at least to some noticeable degree.
