Some kind of passive self-cleaning solar-cell cover might work. You could direct and shape the wind so it blows more strongly over the cell surface to clean it, or since the dust is charged[1] you might use a conductive layer with the same charge. (Although I'm sure engineers have thought long and hard about this already.)

- blululu 4y agoThe static charges necessarily come in pairs so the dust is charged both positive and negative, but the surface also gets charged as dust hits it so trying to blow it off does not necessarily work in the long term. Static dust is a real pain in a low water environment.
