Noticed my neighbor's solar panels were covered in dust last week

Walked past his house on Thursday and saw his panels have a thick layer of dirt on them from the dry spell we've had. Has anyone figured out a cheap way to clean those things without calling a service?

Those panels actually work better with a light dust layer since it cuts down on heat buildup.

Huh, I read somewhere that dust can actually trap heat instead.
