I think TechnoSolis is based out of the Tampa Florida area, and that is where they make their panels, I bought mine from poolheatpumps.com Solar Direct sells a limited selection (1.5 inch header only, etc) private label version of theses under the Vortex name. I paid $2675 for 11 4x12 panels witn 2 inch headers delivered truck freight about 15 months ago. I already had a solar controller AQ-SOL-TC, actuator, diverter valve, etc probably worth another $400 or so. Additional expenses were another $300 or so worth of plumbing fittings, synthetic mounting boards, caulking mastic, etc to deal with mounting on the R panel metal roof, and a paid a roofer (one of the guys that had put the roof on the year before) and his young helper to do the roof top work (my back is not up to such work since I broke it in 2010), I did do all the ground level prep, assembled couplers and end caps on the panels so only one side had to be assembled on the roof, prepainted the PVC pipe for UV protection, did the ground level plumbing, etc. Total labor paid was for about 8 hours of work, 4 hours on 2 days due to getting a late start both days due to weather, otherwise it would have been a 1 day job, I don't recall the exact amount paid for the solar as they did a couple of other little roofing patches while they were there.

p.s. use of a solar cover on the pool really helps cut down on humidity problems with the pool, I used one on my pool for the first time this last winter during the months when the water was too cool to swim. Also solar plus propane would be a great combination in those fringe months when solar on its own just can't get you there, like March was this year, every time the solar would get the water back up into the upper 70's along would come another cold from and knock it back down into the upper 60's. As I recall my water was 78 on March 1, and about the same on April 1
