In the end I was able to convince the customer to remove it. We moved a module from the end to the middle where this broken one was and cut off the excess rails.

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 style="font-family:arial,helvetica,sans-serif"><br></div><div 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).
