The same shutters are on top of the "left" banks as well. But I think the "light check" for the solar panel is done on one of the four blocks, not all/any, just one specific one. If your image is any indication, the second panel from the left in the shown orientation is the one covered by the shutter. (On the left side, the third is covered without issue..)
EDIT: The obvious solution from that, would be to place the right side bank as "on face" on the wall: that way the ends will swap places, but it should still look somewhat symmetrical. Dunno if solar panels allow for the rotations though.
