Age old question....but??

Question

So I think I'm almost ready to put a few solar panels up on my fiberglass roof. The only thing I'm really concerned with is the mounting? For lack of imagination at this point. Let's assume I'll be using 4 Z brackets for Panel...and yea, I'll screw them down but I'm wondering what else....the 3M tape? The 4000 or 5200 adhesive sealant? Eternabond adhesive sealant? Should I use more Z brackes?

Anyways, the whole idea is to be extra confident that the panels are staying where mounted.
Thanks for any input....

NEVER 5200 !  It will fail (at least as a sealant) and it is next to impossible to get off !  The 3M tape pressure sensitive tape does a very good job of bonding.I am also of the opinion that NO SEALANT LAST FOR EVER !  You are better off putting a wad of butyl around the screw between the bracket and the roof and be prepared to replace it in 3 - 5 years.

I’ve never seen an RV solar panel along the road. If it concerns you use six Z brackets and glue or tape. You’ll love your system provided you have adequate batteries, wiring and panels coupled with a good controller.

I would use Dicor Fiberglass Roof Coating. Proceed by the steps below.Roof coating under Z brackets &gt; screw down Z brackets &gt; cover Z brackets with roof coating

Don't use Z brackets as they are difficult to remove when needed. Use alimunium angle, cut 2 pieces and bolt them together for your Z bracket.

Angled aluminum sounds like an interesting thought....in that way, the brackets could be cut as needed. I'll have to check into that. Thanks???? thanks to all for ideas!
