I worked with a guy who had done installs in Arizona. He had an off-grid customer spray down their array with cold well water in the middle of the day, which shattered the module glass.
I’m sure it was an isolated incident, but it happened.

Do not click links or open attachments unless you recognize the sender and know the content is safe. I don't understand the thermal shock nonsense. It routinely starts downpouring here when it's blazing hot out (sun showers) and the rain is way cooler than ground water in summer. It makes no sense. If hose water from the ground is going to hurt solar panels, you better not put them where it rains! I replied privately to Dana, but for the benefit of the group, it takes a heavy soiling to make any appreciable difference. I have done numerous tests at times of high pollen and found little to no benefit to cleaning solar panels. Certainly it would not be worth paying someone to do it. Other climates may have different results. My suggestion would be to test first. Module level power electronics can provide incontrovertible proof.

Yeah rain does a good job with the dust but there is a film mostly on the edges. What does everyone do for cleaning? My array is 16’+ tall on a hill side. I have a pressure washer & was going to pick up a large sponge type mop & mount it on a painters extension pole. Good Biodegradable cleaning solutions? _________________________________________________________ Dana Orzel GREAT SOLAR WORKS!
