I have 11 solar panels on a two story roof. The gutter is approx 22' off the ground and then the roof slants upwards so that top of the solar panels are at least 27'+ from the ground. The pool & solar was installed approx. 1 year ago and I noticed that when the solar is running, I would feel very hot water coming into the pool from the outlets or water features, but it was not continuous. The water would be extremely hot for a few minutes and then go back towards a normal temperature...and then a few minutes later it would be very hot again. Now, as I think about it, and learn about solar, it occurs to me that shouldn't the temperature be consistent coming from the solar panels? If the solar is running, why would the temperature vary?
My variable speed pump runs at 2350RPM when the solar kicks in via the Pentair system. My solar installer actually had it set to a lower speed, but his method of determining the proper speed was based on feeling the solar panels on the roof and figuring that as long as they were not too hot, then there was good flow.
I'm wondering if I should be increasing the RPMs until the water returned to the pool is just slightly warmer than the pool water?
