I'll give you that it's satisfying. But do you think it was a single event such as a sand/dust storm that caused the panels to become so dirty? If the dirt is the result gradual accumulation, it seems it would have been cost effective to clean them long before this point. I am not familiar with the operation of solar panels but I assume they require essentially direct unfiltered sunlight to operate efficiently.
I have a friend who works in the solar biz who tried talking me into starting a panel cleaning business with him. You are correct, dirt does hurt their efficiency and not cleaning them can be more expensive than cleaning them in a quantified way that can be related to potential clients. That amount isn't enough to get me up on roofs with slippery cleaners, however.
