The other reason venetian-blind trackers don't make sense for photovoltaics is that, even if the selective shadowing DIDN'T reduce the power disproportionately, any shadowning at all defeats the whole purpose of rotating the panels. A venetian-blind arrangement, as a whole, will still present the same reduced cross-section to the sun as if the panels weren't rotating (unless there was a BIG gap between them).

With panels mounted close together (which you do to avoid massive lever arms on your structure tearing it up from wind load) you need to rotate the set of panels as a unit to collect more sun than if you just left them pointed in the good-at-noon direction.
