This shouldn't be a shading issue, maybe those two panels are dirtier than others (bird poop or something) or maybe there is an issue.
Thoughts?

Are the two panels you referring to more in the sun than the others? Panel efficiency actually can drop due to heat, which is why our market optimizes Solar a bit better since we’re not getting the consistent heat levels of say a California/Texas/Arizona.
If they’re not any more exposed to the sun, if it’s not a shading issue, and if the panels aren’t dirty (doubtful they are with the amount of rain we’ve had), than it’s potentially an inverter issue (assuming you have Microinverters that take 2 panels per inverter).
