I don't have a pool, but I am wondering: Isn't a pool already getting good
solar heating from the sun simply shining on it? Even if a pool is
light-colored, it probably absorbs about 50% if the light hitting it. So
adding a separate collector with something like 15% of the pool's area wouldn't
make a huge difference int he water temperature.
I would think that a dark-colored pool cover would be far more effective, since
it would absorb a lot more sunlight, and prevent evaporative cooling (and water
loss).
