They are SolarIndustries panels. I have 55% coverage on an eastern facing roof, not the best setup as I lose the late afternoon sun, especially in the early spring and late, late summer. One nice thing about SI is that you can get a good variety of panel lengths, I wound up going with 8 4x14 panels, the extra 64 sq/ft was worth it (ran out of roof length or I would have added another panel). I have an Aqualogic controller.
I have the system running now, it has raised the pool temp from 51 on opening to 59 now in about 3 days of running. I expect the kids to be swimming in a week or so. The system keeps running for at least 1/2 hour after the sun has left the roof, it just sucks the heat out of the roofing tiles!
