Well again we are repairing solar panels - it seems every year there is a new pinhole, crimp, slice, pinch or whatever. We have glued with some minor success, but once we roll them up for the winter and remove to install in the spring, the last year's glue job is now coming off and we start over and add a few more.
Earlier while Googling, I saw a YT video with a gentleman fixing with insert connectors, rather than plugging or glue - anyone think this will work with the poly panels commonly used for our pools? They were 1/4" double barbed Rainbird connectors for irrigation/sprinkler systems, etc. Like a stent for a blocked artery! Looked relatively easy. I noticed that the "repair" kits sold by Fafco use 1/4" plugs. Will these fit the ID of our FAFCO panels? Mine are Solar Bears 4x20 - I have two of them running parallel on a standing rack system alongside the pool with hard plumbing (pvc) to/from the pool. We have had them for many years so I admit we've gotten a lot of use from them but from spring #1 following purchase, we've been fixing them. Too spendy to replace every danged year!
