I would rely on wind to clean the panels, but if there was no choice but to use the arm or lose the mission, a more effective approach than scraping would probably be to use the arm to bump the panels a few times, hoping to dislodge dust and let it be carried away by the wind.  Do it at the windiest time of day - we are getting that information - and hope for the best.  But wind will do the trick without any help, I am sure.

One of my university professors back in the day said that they really wanted to equip solar powered rovers/landers with air compressors or fans to blow the dust off but that would be a mass hit which NASA would rather spend on instruments.

Mars could've given us a break, but it didn't. The HP3 mole started hammering itself today, and almost immediately (after just 5 minutes) appears to have encountered a rock. After four hours of hammering, it may have pushed the rock aside, but doesn't appear to have buried itself completely beneath the soil yet, because it's still measuring temperatures consistent with the Martian air temperature. No matter; they'll try again Saturday. Patience is the theme of the InSight mission.

Mars InSight Lander's 'Mole' Pauses Digging
Quote
"The team has decided to pause the hammering for now to allow the situation to be analyzed more closely and jointly come up with strategies for overcoming the obstacle," HP3 Principal Investigator Tilman Spohn of DLR wrote in a blog post. He added that the team wants to hold off from further hammering for about two weeks.

https://mars.nasa.gov/insight/multimedia/raw-images/?order=sol+desc%2Cdate_taken+desc&per_page=50&page=0&mission=insight

If you go there and click back through the images it looks like they are taking individual images of the horizon now, moving the arm a bit each time. So my guess is that this is part of the big panoramic image they want to take.

Just the horizon bit of the panorama.  There is approximately 1 full image missing from the full coverage of the horizon.  Below, a stretched version to show subtle topography more clearly.  The sinusoidal shape of the horizon is an artifact (not just due to tilt, it's an error in mosaicking).

Is it possible for Insight's robot arm to sweep off the dust from the solar panels when power levels start to get too low? Is that something they considered when designing it?

Might be worth a try at the end of primary mission when the reward is worth the risk involved in using the robot arm to clean the solar panel. It might damage the cells but if they don't try Insight will stop working anyway.

It has no brush, so it couldn't do that if they wanted to.

NASA considered solar-panel cleaning systems (compressed air, brushes, etc.) for the MER rovers, and decided they were not worth the weight. It was easier to just make the solar panels a bit larger in order to compensate for dust settling on the panels. InSight's solar panels are similarly designed so that even with some dust cover it will produce enough power to complete the primary mission.

However, last I heard NASA was doing some research into a system which would create an electrostatic charge to push dust off of solar panels. It doesn't have any moving parts, doesn't require a lot of power, and could be run every few days to prevent dust build up. I do not know what the status of that is.

Wow they really found a flat and boring bit of Mars. Although I think that's exactly what they wanted for this mission xD It's much less rocky than Viking 2's landing spot.

#InSight in sight! Among a new showcase of pics from the ESA/Roscosmos Trace Gas Orbiter (TGO) is an image of the NASA InSight lander – the first time a European instrument has identified a lander on the Red Planet. #Insight arrived on Mars on 26 November 2018 to study the interior of the planet. Images of the lander have already been returned by NASA’s Mars Reconnaissance Orbiter, but these are the first images from TGO.

NASA's Insight lander snaps ghostly, hazy Mars sunset

Quote
But watching the sunset over a vast, red, endless desert might be just as good. Especially when that desert is over 150 million miles away.

Thanks to NASA's InSight lander, which has planted itself in Mars' flat, smooth plain Elysium Planitia, you can do just that. The image above was snapped by NASA's most recent Mars transplant on March 10, the robot's 101st day at work on the Martian surface. Stitching a sequence of images by the lander's Instrument Deployment Camera (IDC) shows the splendorous sun setting over the Red Planet and disappearing beyond the horizon.
