I made a solar panel farm behind some jebs doors so I could hide them when I did not need them. How ever after I got it set up and running I noticed it was not producing the correct amount of EU. Checking each section I noticed while some are producing 4 EU some are producing 3 and some even 2. Here are some screen shots. (sorry for the links but I can seem to post images right onto the fourm)

If there are any other screens that would be helpful please let me know.
Also will redstone power stop a solar panel from working?
EDIT: Tested angles idea they worked fine, how ever I could not duplicate it with just a small panel of 4, tried with larger array of 25 still worked fine, then then an 87 array, it bugged out saying only 71 power.
Edit two: Here are some screens
