You will regret using Z brackets when you want to access under the panel for any reason. Cut 2 pieces of angle aluminum from HD and bolt them together in a Z pattern. Easy to remove that bolt.
To add to the above from my boating experience: "You will regret using 5200" if it's anything you might ever want to get apart. If you do the two-piece bracket as suggested here, sure you can 5200 one bracket half to the roof and the other half to the solar panel. It isn't an "epoxy" but 5200 poly-something comes close.
Use stainless machine screws and nylock nuts, too. I installed vent covers with the supplied hardware which was stainless but with flat washer, lock washer and standard nut. Nearly all have come loose.
Stainless self-tapping "sheet metal" screws for the roof too, if you decide on screws there. Adhesive/Sealant should keep any water out, but if the threads ever rust, all you have is a small nail into an oversized hole.
