They seem to be interested in selling the nice polar bear kits, some number
of panels per the size of the pool. That's it. http://www.fafco.com/
They don't like north facing in their charts.
They also want to use the existing pool filter pump for circulating the
water, which seems all wrong to me. I run my filter at night, not during
the day, unless I am in the pool. So the only solar heat I would get with
their intended setup would be while I'm in the pool. That does not seem
optimal to me.
I think I am going to put in separate plumbing for the heater, and run a
solar panel and small DC motor. If there's sun to power the pump, there
should be sun to heat the water. Seems like a good match to me. I suppose
I'll need a battery for starting surge current, but the panel should be
sized to drive the pump.
I have a 9000 gallon pool. My roof is at 26 tilt, and I have two faces
nicely available, at 124 or 214 degrees. I think the 124 would be best, as
it will get more sun earlier in the day.
First, domestic hot water, then the pool. Maybe some integration, if it

I don't have any real numbers written down, but I can say with one of
I was able to get my 15k gallon above ground pool near Baltimore up to
nearly 100 degrees by the end of June.
