Re: Use inclined solar panels
So yeah, a lot of the hate on clearing dusty panels on mars seems to be an assumption that it need to get them back to clean, as opposed to slowing the accumulation or getting it back to a more useful yield. If you over provision a bit, and use a smaller RTG if appropriate, you can address some of this, and the panels aren't made from Kleenex. They need to stand up to a martian wind storm, they can handle the occasional wipe down, and the engineers here on the ground can balance the risks. They literally made a solar powered drone work, this isn't impossible.
That said if a bunch of you are grouchy about the limits on using RTGs on space gear, I hear you. I'd rather not have them burning up in the atmosphere on a regular basis, so keeping them out of disposable LEO stuff makes sense, but it shouldn't take an act of congress to get them for literal extraterrestrial missions.
