Which Velcro / hook & latch for flexible solar panels

[Capt.Don]

I am so confused; what I thought would be a simple search for Velcro to secure flexible solar panels to my bimini is turning out to be difficult. What I'm trying to do is follow the advice from marine how to to sew "lapels" with adhesive Velcro on the top and bottom of the solar panels and corresponding sew-on Velcro on the fold-over lapel.

It seems like various websites suggest "Industrial Strength" Velcro. Where it gets confusing is this is a nylon based product, where Sailrite and others recommend polyester (better UV, water resistance....). To complicate things, even in the Velcro line, there's different hook and loop strengths and different adhesives.

I need both sew-on and adhesive hook & loop around 30' with the sew-on hook/loop working with the adhesive same loop/hook.

One option would be to use sew-on for both sides and use double-sided tape to attach to the panels and velcro. That way I could use polyester, without worrying about different hook & latch patterns, etc... Which double-sided tape would you recommend?

Any other recommendations? Thanks,
Don
