<div dir="ltr">Jay<div><br></div><div>Not sure what you are implying by this comment. I do not believe that glass is pre bowed by any glass manufacturer that I know of nor on purpose by a module manufacturer. Glass is manufactured shipped and stored flat on a pallet. How were the modules Shipped? If glass down with no packing in the middle of the glass to prevent sagging from truck vibrations, I would say that is the best explanation. Also I believe it depends a lot on how the glass is attached ( or not attached to the frame. Worse case no adhesion or just a rubber gasket would allow sagging from shipping glass face down or up. Best case a fully cured adhesive before shipping. If they are using PV adhesive caulk, (special w/o curing agents that can corrode electronics) and ship before it is cured it almost as bad as no adhesive. It is pretty much known that the best seal the edge of the glass in the frame with adhesive, cure properly and then ship on edge rather than glass up or down in the flat IMHO. </div><div><br></div><div>Bill</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Nov 18, 2019 at 11:57 AM Jay <<a href="mailto:jay.peltz@gmail.com">jay.peltz@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto"><div dir="ltr">I\u2019m wondering if it\u2019s designed to account for gravity sag once the modules are mounted.
