Cleaning Solar panels

Things are changing pretty fast in solar as far as cleaning goes. A couple of years ago when I searched for information about cleaning solar panels, it looked like no one had anything to say. Now it is different. Not only do you have information suggesting dirty panels can cost at least 10% loss in production, but there are cleaning services listed in some communities, and there are automated cleaning systems.

This is a system that includes a sprayer for each panel, filters and soap dispensers. It can be set to rinse between wash cycles. I am not suggesting this is the answer. It is hard for me to see just how effective this system would be in my area where it takes a bit of scrubbing to get the dirt off. But if you are in a fairly low dirt area, it might be fine for you.
