Excellent question. It's easy for dust to be sucked into the intakes,
but (I'm not sure why) relatively little completes the convoluted path
to the front absorber/heat exchange section, although the almost five
year old 12' panel in my shop has managed to accumulate a fair amount
of MDF dust without having its performance noticably degraded.

If the dust accumulation reaches problem levels, the only remedy is to
remove the twinwall polycarbonate glazing, vacuum it out, wipe the
aluminum slats with a damp cloth, and replace the glazing.

The building owner and I had a discussion about the desirability of
shop dust collection yesterday. :-)
