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?
Mine is a new install (~5 weeks) so bird poop or dirt wouldn't be an issue yet and not a huge sample size, but generally all of my panels seem to be within 5-10 watts of one another. (Only exception is when shading becomes a factor....like in the evening I can see the difference the shadow of my neighbour's chimney stack makes on 2 panels compared to the rest of the system )
