[RE-wrenches] Attaching PV with VELCRO

[Matt Partymiller]

We used to see Unisolar go to market with hook and loop attachments.  Never installed any myself but there were definitely a number of those systems installed.  In fact, we were hired to remove a decade-old hail damaged array from a school in 2020 – roughly 200 kW.  The hook and loop attachment method was mostly successful but had failed in a few areas resulting in edges coming up a bit and ponding on the laminates.  Other failures to the modules were as significant as hook and loop failures.  Far from the worst array I’ve seen.

Thin film like Unisolar but with Velcro?? Hard to see it making wind requirements or lasting.

Thx for the smile

Wrenches,

As far out as the subject line might seem, a company in Italy has apparently developed a system for attaching PV arrays to flat roofs using strips of VELCRO<https://www.generalmembrane.it/sites/default/files/Brochure-General%20FIX-ENG.pdf>.

The potential advantages of this system seem hard to ignore:
   - lightweight
   - no ballast required (also, no mechanical attachments)
   - quick installation and easy assembly

Has anyone ever encountered anything similar here in the states? Any opinions about the feasibility of this approach?
