Always pass water through solar?

[bradatkins]

Hey -

Just installed my solar system (4 2x20 panels), and it's working well.

I run my pump during the day to obviously take advantage of the sun. I run it 8AM-5PM.

Today, it was off at 5PM but it was still 30C outside and the sun was beating on the panels pretty good, so I turned the pump back on.

The thermometer for my salt system was reading 92 for a bit (while the water in the panels was evacuating I guess). Then it came back down to about 77.

So my question I guess is, do I have to leave my pump running whenever it's sunny out so the water in the pipes doesn't overheat? Or is it OK to just let it sit there?

Obviously draining them, by taking off the end cap, every day isn't practical.

Thanks,
Brad

If your panels are installed above pool level then you can add a vacuum breaker valve to let them automatically drain whenever the pump is off.

hmm. My panels are installed above my pool, and I do have a vacuum breaker. Perhaps the breaker is broken?

if you have an air valve then they should drain when the pump is off, maybe something isn't set up right.
