Below I've cropped out the West solar panel array, which shows surprisingly tall vertical ridges that extend the full length of each of the ten segments where it joins adjacent segments.
Are these related to the way the panel unfolds? Do they have a function now that the arrays are fully deployed? I would think they might tend to trap Martian dust blowing in the wind and interfere with any cleaning by subsequent wind or dust-devils, but maybe the effect is just the opposite?
One thing I worry about is what @Uwe had mentioned in comments earlier; that blocking one
junction† cell in a group of series-connected junctions† cells causes a much larger current drop than you might estimate from the fraction of the total area covered. In some wiring configurations small shadows can become big problems and big losses.
† As pointed out in comments, these are triple-junction cells, so unlike the old silicon cells that had but one pn junction per cell, these have three, stacked directly on top of each other. https://solaerotech.com/
