I'm wondering if any experts can help determine whether my expectations were too high on my purchase. I have (2) 4x 20 solar bear panels 12ft away from my 24' ag with approx. 13,500 gal capacity. I ran them for 4 hours in good sunlight (south facing) and was a bit diappointed to see a 1 degree increase. In the past, I've observed a 1 degree increase on 4 hours of sun prior to installing the solar panels. The panels appear to be plumbed correctly (I did it myself) and I followed the instructions from Fafco religiously. While the pump is running water through them, the panels feel nice and cool when compared to the adjacent roof surface. I shut it down for about 30 minutes and the panels felt warm. The air temp was about 68 degrees, the water temp was 70 (using a solar cover religiously) and got to 71 before we lost sunshine that day.
If this seems correct, then with 4 hours of pump running to circulate water through the panels to gain 1 degree seems that on a full sun day for 10-11 hours (pool and panels are in full sun from dawn to dusk) I should only see 3 or 4 degrees??? I was hoping to see 10- 12 degrees.
Any input would be appreciated.
