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
makes sense.

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.
