Welcome to TFP!!!
There is not really any glue that works on the type of plastics typically used in these solar panels. Leaks are usually fixed mechanically with plugs (when there are separate tubes) or you can try plastic welding like Isaac mentioned.

I have not yet had any leaks in my Techno-Solis panels, however 2 or 3 other members with these panels or the Solar Direct Vortex panels which are the same panels sold under a private label have had success with plastic welding.
p.s. the problem with all types of glue is a different rate of expansion than the solar panels
