<div>Hi Allen</div><div> </div><div>For what it is worth I had a house in Puerto Rico with two modules on the roof. Hurricane Marilyn blew the roof off of the house but the panels stayed on for the ride. The roof landed upside down pinning the modules under the debris. These the UniSolar UPM880 (non glass) and they survived with minor cosmetic damage and still measured full output after they were salvaged.</div>
<div> </div><div>In Florida we were hit hard again by Hurricane Charlie, with 145 mph winds reported nearby our home. This time the roof stayed on and again so did the pv panels. We were the only place with power that first night since all the grid was blown down. So, modules can survive some of the big winds if fixed well enough and if you lucky. I have been lucky since none of our family or friends were (physically) hurt in these storms.</div>

Fellow Wrenches,<br>
We have an engineer-type whose wife wants badly to do a PV system,
but he puts up barriers. In her words:<br>
<blockquote>Well, I don't know how long ago it was, surely old
technology by now, but some experimental solar panels at Sandia
Labs were shattered by hail and it caused a big controversy. My
husband says it turned him off solar.It comes up every time I talk
to him. Either he is complaining about the wind or the hail or
whatever. <br>
</blockquote>
I get to respond to this, and am seeking specific assistance: Can
anyone send me a link to any formal standards, or reports of
aggregated field experiences, indicating that wind and hail (not to
leave out "whatever") are not issues of concern when PV modules are
installed correctly? Anything that came from Sandia Labs would be
ideal, but it just has to be reputable enough to satisfy a grouchy
retired national lab engineer. Web links, reports, product
warranties, etc. - all good.<br>
<br>
Thank you in advance.<span class="HOEnZb"><font color="#888888"><br>
