<div dir="auto"><div>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! <div dir="auto"><br></div><div dir="auto">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.</div><div dir="auto"><br></div><div dir="auto">Jason</div><div dir="auto"><br></div><br><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Oct 20, 2023, 4:21 PM Dave Tedeyan via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Dana, <div><br></div><div>See attached from REC.
