Question Mounting over fibreglassed plywood question

Ahoy,

I am making a (semi-) rigid bimini, made of fiberglassed plywood, and I want to mount flexible solar panels on top of it.
What is the best way of doing it?

SS nuts&bolts trough? Screws? ... Other options?

My main concern is water seeping alongside bolts or screws into plywood and eventually rotting it.
Also, having bunch of nuts sticking out visible from the inside is not esthetically pleasing.

Any suggestions?
Thanks.

Another alternative, if you don't want potential leak/core problems, is to bond studs to the surface. This panel is mounted to custom studs that on FRP feet that are epoxied on. You can also buy the glue-on studs from Duckworks or Weldmount. They are nearly as astrong as the threads, if installed properly. I've used them for many things and never had a failure.

A nice feature of the studs is that you can use them to adjust for curvature of the roof, avoiding any stress on the panel. In this case, the frame is just 2 lengths of 2" aluminum angle.


See item 80a. http://sail-delmarva.blogspot.com/search?q=studs

With semiflexible panels there are even more options, including 3M Duallock. But rigid panels last longer.

VHB tape.
Choose the right tape.
Bimini frame will come off before the panels fly away.
You can slice it if ever needed.
Has worked well for me.

This. VHB tape has become the go-to thing on a boat for me. Think of it as 5200 that is actually user-friendly, non-messy, easy to use, easy to intentionally remove, but almost impossible to release otherwise.

Skyscrapers windows are held on using nothing but VHB tape.
