<p>Let's see, we're all on the same page here, right? The 33 vs 31
mm refers to the frame height not the thickness of the frame
material where fastener pulled through. <br>
</p>
Also, hang in there with getting help from Solarworld. They have
given me exceptional help in the past...not sure if they can/will in
this case, but.....<br>

HI Steven;<br>
<br>
Do you mean the bolts were over torqued and then later broke?
Here's some pics that just came in of the damage. Hardware looks
good, just ripped the module's framing. The old Solarworld 2.5
frame not only was thinner (31mm) and so could possibly flex more,
but it had less metal to bolt to. Their newer 4.0 frame is 33 mm
thick, but also appears to have a wider flange to bolt to. I
still have not had any contact from Solar World. Not good. I've
been installing their stuff since the ARCO days, so I need some
support for the first time in decades. Solar World Reps are you
out there?<br>

<div>Hi Ray,<br>
<br>
</div>
Have you checked the torquing on all the other bolts? My
company's had a few projects where some modules blew off -
it's always been due to over-torquing of the bolts.<br>
