I went a step further. Had a local fabricator build a steel rack from
2x2 square tubing that was mostly welded together. It lasted several
more years, and many more storms until we needed to add a few more
larger solar panels.

We were just talking about this the other day. On our second solar
site, we had a storm that effectively "disassembled" . It was a Unirac
side-pole mount similar to the one pictured below my signature. It was
made from extruded aluminum and bolted together with stainless hardware.
The wind built up some kind of sympathetic vibration, and about half
of the bolts and nuts came loose and fell to the ground. The ones that
remained were pulled through the aluminum extrusions, which then bent,
twisted, and "took flight". At that time we had 2 150 watt panels
installed. One of the solar panels landed 100-150 feet away, and
landed in soft mud. Except for a couple of minor bends in the frame,
it was intact, and still functional. The second panel landed about 1/4
mile away, and was almost completely disassembled. Quite a sight in
retrospect.

I would sure like to study the ones that are left and try to
determine why some ripped off and some didn't. Lots of really good
research opportunities there.

I wouldn't be surprised if a lot of what's left disappears...
