Solar Heating

[JMCFAN]

I purchased a set of Ebay last year ( much cheaper...) I have a 21x41 with a 6' deep end. I plumbed the panel to one of the outlets with the divertor vavle... when on the water is very warm entering the pool. I only was able to use 1/2 the season but it worked very well.

mine is mounted to a framework i constructed at a 45 degree angle and against the side of my home "south facing".... gets a lot of exposure..

I am running 2 2x20 panels on the ground next to the pool. Last year I seen a jump in temp of about 4 to 8 f using a solar cover. The units I am using have a rated output of 1000 btu per sq ft per hour. 1 btu = 1 pound of water 1 degree per hour. I gal of water = 6.3 to 6.6 lb ---> 151 gal of water 1 degree per hour * number of sq ft. For my self that is about 12000 gal of water 1 degree per hour based on 80 sq ft. I can get about 7 hours of sun where I have my panels set up so I the math lets me get 6.28 deg f each day. But in the real world it is not so predictable. Wind, ground temp, and other effect the panel.
