I’ve got five 6’ X 3’ solar panels on the roof that heat the cement pond in the winter. The people we bought the house from five years ago had a fire in the fireplace, a hot ember got out of the chimney and burnt a small hole in one of the panels, causing a drip. I pointed it out to the seller and he had some guy patch it with some black gooey stuff.
Five years later, it’s leaking again. I asked all of the pool stores in the area, and they say it can’t be patched, but they would be happy to reinstall a new panel for $800.
I know this can be fixed. I can’t figure out what I should use to do the patch though. I think the panels are a type of PVC. Water is pumped up to them and then it’s gravity fed to the pool, so pressure inside the panel is not very high.
I was thinking a simple patch kit similar to the kind used on beach balls and pool toys etc. would probably do the job, reinforced with a silicone sealant.
Any plumbers or pool techs or anyone else with solar heat knowledge have any ideas? I’ll buy you a beer. Thanks.
