Hi Jesse, 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.
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? Keep Shining!
