Heliocol Solar Panel Repair Kit

Easy to use straightforward design. The plugs for the repair kit are a little finicky. About a quarter of them I believe to be a manufacturing flaw as the installation tool pokes through the rubber plug during installation. That's even after stretching by hand with spray silicone as they recommend.

The plugs don’t work very well. The rubber that you shove into the hole is too easy to poke a hole in with metal piece and then the plastic pieces you’re supposed to shove into the center of the rubber break too easily.

Worked perfectly and save me somewhere between 4 and $500 in repair costs.
