Can anyone recommend a specific brand of solar panels? I can not find any local dealers in Pittsburgh PA area -- so I'll have to order and find a local contractor to install.

I have a 20x40 IG pool (3- 9 feet) vinyl pool with a 2 story directly facing south roof. I have a heat pump - but want to go with solar. I want permenant mount - but I can only get about 6 panels (4x12) on roof. Pool is not open until May. I've been looking at Harting Industry Hi Deluxe sold at http://www.solartrope.com/new/pool2.htm.

Any recommendation is appreciated.
