Put the drone up this morning to look at the array again. I had it up while they were cleaning yesterday. Judging by their reaction, I'm not sure anyone has ever done that before.

They are cleaner than yesterday, but perhaps not as clean as I might have liked. They used a hose and scrub brushes but no soap. Plus, the water is hard. We'll see how the output goes today, weather looks similar in terms of cloud cover.

If I can figure out a safe way to get on the roof, I may try to do it myself next year, with soap.

We're still making more power than we use and the "problem" is likely more cosmetic than production, but if I can get more from them, I want it.

I put a "before" and "after" example up on Flickr.
