First, we wanted to buy in the Villages but opted to purchase near Winter Garden to be closer to our son's who live in Orlando. That out of the way, here's my experience with our solar unit. We have six 12 by 2 Heliocol panels mounted on the south side. We have black PVC from the filter across the east side of the roof over to the south side. We have been between 70 and 80 degrees since Halloween dropping to 67 when we had 3 days of clouds and rain. We have reached as high as 86 when we had several days of warmer temps. If I divert to the spa only on a clear sunny day over 60 degrees, the spa will heat to between 90 and 98. The weather prediction is for warmer temps by mid-week so I expect to be in the mid-80's by the weekend again.
