What is the best way to know that you have the optimal water flow through your solar panels? I know the panels should be cool and the water should be approx 4 deg warmer, can you have too much flow?
mas985 said:With 288 sqft of panels, you really don't need more than 30 GPM for the panels and you are more than likely well exceeding that flow rate. But one concern I have is that your filter pressure is way too high for those RPM settings. So I would like to get some more information about your plumbing setup.
Pump elevation relative to the water level
Filter type/size
Suction side plumbing diameter, length of runs, and number of runs from pool to pad
# Suction side valves if any
Also, when you shut off the pump does the pressure gauge go to zero?

Short answer is no.bobby1017 said:At 30 gpm it would take 18+ hrs to circulate the pool once, I'm only running 10 hrs right now, would'nt that decrease the rate that the pool is heated? What I mean is if the flow was 50 gpm it would turn over in 11 hrs, so would'nt this heat faster?
Your plumbing setup has the highest head loss I have ever seen on a pool. I still think there is either something wrong with the filter gauge or the return plumbing has an issue somewhere. But assuming it is an issue with the plumbing and the filter pressure is correct, then here are the estimates that I came up with:At 2600 rpm, solar on, poolcleaner & booster pump on, pressure is 21 psi.
