Fafco Solar Panel system - how to bypass sensor?

I have a Fafco Solar system for my pool - it is at least 15+ years old. Recently the mechanism (sensor) on the roof that allowed the heated water to pass to the pool stopped working, it was in a round cover and disintegrated so I am not sure how things were attached inside. My goal is to set it up to manually allow water to pass to the pool, but I am not sure how the plumbing or the use of the hoses that were once attached to the mechanism worked (3 hoses that go from the pump plumbing to the roof). I'd love any thoughts on how to make this a manual system. My inquiries to local dealers has discovered that the replacement for this mechanism would be costly since it would require a full replacemnent.

SOURCE: swimming pool solar heater panels freeze problem

Depending on the manufacturer, your solar panels may be replaced under warranty. Our installer says that once the panels begin leaking, they tend to deteriorate fairly rapidly. For example, three leaks the first year, 7 leaks the second year, 30 leaks the third year.

Many solar panels are warrantied against freezing, but that is not likely to be the future of the warranties, because they inevitably DO freeze and leak.

If there are just a few leaks, it is easier to fix them - a Fafco Solar panel repair kit can usually be bought from your installer for about $25.00.

If you turned the pump on to manual to circulate the water through the panels, that should prevent a freeze - but will cost you the electrical cost to run the pump.

Our experience has been that it is better NOT to drain the panels - we had many fewer leaks the years we have not drained the panels, despite occasional hard freezes in our part of California.

In addition, your rooftop installation should help radiate some heat up to the panels to keep them from freezing.

Check your warranty and get the panels replaced if there are more than a few leaks.

Had my roof replace so had plumber remove solar panel and reinstall now the water does not circulate and the system just flashes


The two pipes that connected the pump system to the solar heater were probably capped and they should have been connected to cause normal water flow. I hope this helps.

Honestly, I think you are over thinking both your problems. Reduce to 1.5 inch pipe as close to the ground as possible. It is more work for your pump to push water up a 2" pipe then a 1.5" pipe, but it will do either without any real problem.

As far as mounting your panels, as long as they are above the water level of the pool the water is going to drain out of them just fine. You can slope them slightly, but you don't need to.

There are many variables to this......

How big is your pool how big is your solar system.

Solar temps don't rise quickly ever, and definitely not when the temp is only 75 outside.

You need 80-90 degrees or more on the roof to see quicker results, if the water temp is currently at 70 and it's 75 degrees outside and 80 on the roof you will barely get any change.

You will also lose the heat at night due to lower temperatures.

Once it's hotter outside and warmer at night you get the gains and keep them.

Hope this helps

If you want all your water going thru the solar heater before re-entering the pool, you'll need to plumb the end of your filter to the solar heater, then the water exiting from the solar heater would go where the filter hose did go back into the pool. Hope this helps.

Support of 4x20 panel


The picture obscures the fact it is mounted on plywood panels which are leaned against the pool.

The manufacturer does not offer any sort of support for it. You'll need to install it however it bests fits your pool/yard.

Support of 4x20 panel


You will not be able to lean the solar panel against the pool. You can lay it flat on a deck or even in the grass. You can also build a rack. Mine is at about 30 degree angle. I used plastic plumbers tape to attach it to the rack.(don't drill through the panel) The rack is 4' x 20'. Green treated 4 x 4 legs, green treated 2 x 4 frame, And green treated plywood top. If you can face the rack south you will have sun on the rack all day.
