The hole for my pool has been dug and they are coming to install the actual pool mid next week. I am considering installing a solar heater when the install is complete to extend our seasons but wanted to get some opinions. I would like to install myself. My pool is a kidney shaped pool that is about 19,000 gallons and has a surface area of 594SF. I have a detached garage adjacent to the pool that has one pitch of the roof pointing east and one west. The detached garage is 20 x 30? I was thinking installing solar panels on each pitch of the garage. I am near Columbia SC so we have mild winters and smoking hot summers. I understand we probably still couldn't swim year round but how many months out of the year do you think we could get out of it with solar heat? Can anyone point me towards a good diy system to use? Estimated cost for a good solar system? Life expectancy of the system? Thanks for any help you can provide.
