<div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Hi Jesse,<br><br>I'm curious about what you are seeing. We've seen better performance than that on arrays with those modules, but don't have module-level monitoring available on any of our systems. Does it look like there is a bipass diode failure with the shattered modules (probably covered under warranty), or was there something like lightning near your ground-mounted system? We have a customer whose home received a direct lightning strike recently (no fire or human injury!), and 100% of the PV system needs to be replaced (except flashing/racking), unfortunately. <br>
<br>I thought the delamination issues were only (or mostly) generation 2 modules and only in our state, but wonder if any installers in other places (WA?) are seeing this too?<br><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">

William Miller has some nice ideas on his website regarding protecting circuits. I've used his ideas on one project and the inspector liked it.<br>
<br>
Silicon Energy makes a module with raceways for output circuits. Their module is expensive comparatively speaking and I've never seen one of their 190W modules produce over 155W (using Tigos to monitor) they've also had some delimitation problems with modules made here in MN and one of my Silicon Energy systems has two modules with the glass shattered on it that I discovered today.<br>
