Is it probable that the solar panels from the Mars rover get cleaned by a storm or anything else?

Yes - actually, this happens quite a lot, and this is part of why Spirit and Opportunity lasted for so long. The Martian wind partially cleans the solar panels, so although they quickly became fairly dusty, they still ran fairly decently for quite a long time.
