Seen 4 panels this month with the same yellow corrosion at the terminals, all installed after 2019
Pulled a Vista 20p off a wall in Mesa yesterday and the terminals looked like they'd been in a pool for 15 years, not 3. Turns out the new builders in that subdivision skipped the vapor barrier on the exterior wall and I'm finding this on every job now, anyone else seeing the same thing on newer builds?
