<div>Hi Jason,</div>
<div> </div>
<div>We just removed 2-3 shattered mods from the roof of the old KACO HQ because, in my opinion, the shattered glass poses a fire hazard by exposing normally protected electrical connections. The risk may be small but if there is any risk present what-so-ever, I want to mitigate that. I believe you made the right call by refusing to do the work as you may be liable in the (however unlikely) event of catastrophic failure at the mod in question. The array won't look so nice anymore if half of it is melted and charred. Play it safe. Get rid of it.</div>

<div style="font-family: Calibri,sans-serif; font-size: 11pt;">If it will be removed electrically from the system, perhaps you can come up with a way to apply a clear sealant coating across the face of the module to decrease further degradation by the elements.</div>

<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;">I came across shattered glass on an Evergreen PV module while doing a new homeowner system evaluation. My inclination is to remove the panel and bypass it, which would still leave the array well within the operating parameters for the inverter. However, the owner wants to just leave the panel physically in the array because it actually looks better that way, which I agree it does. You can hardly tell it's broken from ground level. </div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;"> </div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;">I explained that there is a risk of a ground fault if the module is left physically in the array, but the owner who is pretty astute, mentioned that the fault voltage if a ground fault were to occur from that module would only be at 22.5V potential (he didn't mention the actual voltage, but he did correctly state that the maximum fault would be limited to the single module, which in this case is 22.5V @ 12A). While it may trip an inverter, it would probably not pose a safety risk.</div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;"> </div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;">While he may be technically right, for now I have reused to do the work, but I told him I would think about it.</div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;"> </div>
<div class="gmail_default" style="font-family: arial,helvetica,sans-serif;">Anyone been through this scenario?</div>
