You can just dimension and gematrically design said mirror gutters to not accumulate much sand if said particles are just flowing away.

OFC one shouldn't try to build a solarthermal powerplant on top of shifting dunes - that would be stupid.

The majority of desert is rocky tho, so maintenance should be minimal if not lower than photovoltaic panels since those would likely have fine sand sticking to the glass and said glass gets scratched up...
