I have been trying to figure out the best way to heat up my pool. I have a rooftop solar system that works when my pool pump runs. Unfortunately the power demands of the 3/4 HP pump are very high. The electric bill is overwhelming.
I want to run a couple golf cart batteries or other 12V deep cycle batteries to a 12V marine style bilge pump. I would charge the batteries with the solar panels.
The existing roof top system is about 300 square feet of skinny black rubber hoses. On a sunny day the water comes out pretty hot. If I can run the solar heater for a longer period of time the pool will get warmer earlier in the season, and stay warmer later in the season.
The roof is about 14 feet up, so the pump would have to push the water up 14 feet. I may not be able to find a pump that can do that, or it might take too much power.....but I could set up a secondary system at ground level.
I don't expect to move a whole lot of water. The pump I currently have moves 500 gallons per hour. It say 12 V, but I couldn't find the amperage or wattage listed.
Originally I planned to run the solar panels directly to the pump, and whenever the sun was out, the pump would run...? Not sure if that would work or not...It would take a lot of solar generated watts to make it run. The batteries would provide enough reserve so the pump could run for 4 or 5 hottest hours a day.
Am I on the right track? Any suggestions for panels or other ideas that would work better?
