Answer:
They note that for a pool 15'x30' you need 2 4'x20' collectors.
That is, collectors 35% of the area of the pool or roughly 1/3.
A 24' round pool has an area of 452 ft^2 so you would need a
collector around 150 square feet. A 3'x4' window is 12 square
feet. You'll need 10 (ten) more of them. :)
Even with a heater, it'll help to have a good cover to stop the
losses from evaporation.
