I was waiting for someone to piece both of these questions together into another question. @Dragongeek was the first, Could a solar panel be modified to create a static charge while spinning to remove dust during a dust storm?
This question asks how dust could be removed from a panel through spinning it: Fast spining solar cells to clear Martian dust possible?
This question asks how a static charge is made with spinning blades: Could electricty be generated from a Martian dust storm?
How could the solar panel be modified for a dual purpose? 1) Normal solar function while there is no dust storm. 2) Bach up self-cleaning mode while spinning to create a static charge from the dust storm.
