No, I'm sure it's not. You have to remember that these rovers were only designed to last 90 days. If they were designed to last longer i expect they would have included some sort of dust cleaning mechanism.

The dust storm isn't depositing sand ON the solar panels -- it is in the atmosphere blocking sunlight from getting to the solar panels.
Have you ever been in a bad dust storm on Earth? It can become pitch black.
Localized dust devils actually help clear the solar panels -- it has happened many times during this mission.
And yes, it is difficult to put "wipers" on the solar panels. There is a lot more that could go wrong than go right when you add additional moving parts (all of which need some form of heating to remain operational).
