Real nice Z Solar mounting brackets on Ebay

I just wanted to recommend these...
Ebay item number 321248100910
I just got them in the mail.
$9.25 shipped for 4 each w/ bolts.
Real nice and heavy.
I ordered another set.

PS... I have no connections w/ the seller.

I am a Solar newbie, first time building my Solar system.
Thanks to everyone, for all I have learned.

These brackets look interesting. I want to mount a rigid solar panel to a fiberglass egg without having to drill into the roof. Does any body have experience with mounting these sort of brackets to the roof with VHB tape (or other sticky stuff)? How well does it hold up over time? Any tricks to making sure you get good bonding to the fiberglass?

Thanks

Wipe the spot to be bonded with acetone. It only takes a few seconds to dry.

The approx. surface area of the bracket is 2 3/8 x 1 1/4 to which the VHB tape would be applied.

Another option, a Simpson Strong Tie, one in each corner would have more surface area. Home Depot has.

I work with several industrial versions of 3M VHB tape. Personally, I don't use it to bond anything on the exterior of fiberglass trailers because of the risk of separation at highway speeds. I have used stainless steel Click Bond fasteners which bond with epoxy with zero problems. A bit spendy ($10 - $15 each) but well worth the reliability. Check out the installation videos online; beating the snot out of one is a great video!

Thanks.... thats a real good option.
I might order a set just to see what they look like.

What do you think of using SS Elevator Bolts and gluing them to the fiberglass with 3M Marine adhesive 5200?

Go here: Technical Information

Then do a technical search for this: Adhesive Sealant 5200 Tech Data

When you download the PDF file, you'll find the shear strength when used with a gelcoat surface is better than 500 psi.

VERY strong bond, provided cleaning of the mating surfaces is done correctly.

Thanks, so why not use this stuff with Elevator Bolts?
Would be cheaper than Click Bond Fasteners?
And good enough to hold whatever, solar panels, etc.?

I have no knowlege in this area, JB Weld is as hi-tech an adhesive as I am familiar with. But, if you are going to glue something that you will have to rip a chunk out of the trailer to remove, why not just drill a hole and rivet or bolt the thing? And then fix a small, neat hole with standard fiberglass techiniques if/when you change stuff out?

I wouldn't mount it - I try to park the trailer in the shade. Makes more sense to me that it be portable so it could actually be pointed AT the sun.

If you mounted it and decided not to use it, you could always grind off the threaded parts and leave the mounting disks attached. Paint them white and you'd hardly notice them.

If you drill a hole you have to put something like an acorn nut on the inside to bonk your head against now and then.
