   I wouldn't bother too much with dust...   
      
   In Mars the wind will clean the dust, so there will never be too much on   
   top of the panels.   
      
   Also if you get really in trouble they can allways put the rover in a   
   slope, by starting to climb a bigger rock, for example, and the wind   
   would clean the solar panels.   
      
   Presuming no other major failures occur I predict the rovers will never   
   fail dues to dust and will work for years.
