It doesn't matter how well you clean the panels if there's no light to capture.

Holy shit it’s been 6 years?! It seems like yesterday i was watching the live stream. Good on the engineers for designing something that has lasted well beyond its intended service life.

Quoted: How about a small compressor and some nozzles aimed at the solar panels? View Quote |

Note to next generation Rover designers... It would be Boss to have a System to clear dust off those solar panels... https://en.m.wikipedia.org/wiki/Cleaning_event |

It's possible that the rover will be stuck exactly where it is until the end of time.........if there is such a thing as the end of time. Maybe we will eventually get up there and pick it up, maybe not.
Could be there forever. Sitting on Mars in silence for eternity. Crazy to think about. |

There's so little air around Mars you're going to have to use quite a bit of power to compress it enough to clean your solar panels that are not supplying power to the compressor to clean the solar panels... View Quote View All Quotes View All Quotes Quoted:
Quoted: How about a small compressor and some nozzles aimed at the solar panels? use the compressors to charge the system during normal ops. And wait till it's needs. |

There was an ARFCommer here on GD a few years ago that designed and built parts of the rovers.
I think the wheel struts. I can't remember his name though. Anyone remember? |

Funny thing is, all these rovers will be in Museums one day - probably the Voyager probes too.

Estimates on the life of the golden record are that it may last several billion years. Realistically, we will eventually get there and put these things a martian museum. |

I have an idea. The solar cells could be mounted on a long trianglar “tubes” that could rotate on the long axis. The top face exposed, bottom 2 faces covered by enclosure below them. If top face gets duty just rotate to expose clean cells. The rotation could brush against some bristles. Have enough of them and you could rotate individual tubes to clean without disrupting power.

I always thought the Rovers needed a dust brush (like a windshield wiper) to keep the panels clean. They don't have one? And didn't a dust storm blow the dust off a rover once, allowing it to recharge? Have enough of them and you could rotate individual tubes to clean without disrupting power. |
