We use a lot of SW, lost our first system this last year on a ballasted
roof mount during a hurricane. Good Solar World contact below, if he is
unable to help he should be able to point you in the right direction.
Patience.

Subject: [RE-wrenches] Solar World Wind Damage
Greetings All;
I just had the dreaded call from one of my higher profile commercial
clients: a remote radio repeater station had modules ripped off the frame
by high winds.
Two SW285s were damaged. The wind was strong enough to rip right through
the aluminum side rails. We had used the proper stainless 1/4" bolt
hardware with washers on the inside, etc. All the hardware was still
tight, it just tore the aluminum past the washers. This is not a top down
clamp system, but uses bolts through the mounting holes on the back of the
module. This was all on a DP&W rack with high wind option.
In 20 years in business, I've never seen that happen. Is there a contact
at Solar World? I'm not getting through on the tech support line I have.
First, I need to know what the wind rating is on the modules blowing from
the back side, and
Second, a suggested fix for the remaining modules.
One module was completely ripped from the frame and thrown 30 yds (total
destruction), a 2nd one has cracks in the Aluminum, but has not let go
yet. I was thinking of adding some angle aluminum on the inside to beef
it up. IMHO, the frames are pretty thin aluminum compared to older
modules. I'll share some pics when available.
As always thanks in advance for your comments,
