Dust on Mars?

If at the Moon, very close to (if not directly under) the pole, the receiver would need to "counter-rotate" against the moon's rotation and angular tilt, right?

"... the receiver would need to "counter-rotate" against the moon's rotation and angular tilt, right?"

The moon's angular tilt is surprisingly small. Yes, the receiver, whether solar cells or solar dynamic, would have to track to follow the sun. A simple photocell-activated clock motor would suffice.

Dust on Mars would be a problem. I would design arrays that could fold up to shield from storms, and a robot arm would be needed for dusting. To avoid such complexities, simple flat arrays may be preferable, with solar cells made of local materials.
