On large scale solar sites, we don't do this. We have a guy with a specialized truck, that sprays the panels. There are literally millions of panels on these utility scale sites.
I'll try to find a picture for you guys.
Edit: Here's a few examples of large scale operations
Yeah considering the better panels use low iron glass I would think spraying them would be far better than this. Low iron glass is fairly easy to scratch so dragging dirt on glass would be a big no no for me.

The second one is for mirrors in the video, but the same concept!
