Has anyone found a cleaning solution that can be sprayed on and cleaned off without needing to scrub the solar panels? A few of my panels are very hard to reach and it would great if there was l foaming chemical solution or something eco friendly that can be sprayed on, let it sit, and then sprayed off. I have what looks like tree sap or something sticky on a few of my panels.

Yes you can use the outdoor window cleaning product. They usually come with a canister that plugs on you hose. You put the product in the canister and spray, it creates a foam. You let it act then rinse

I have found that hail cleans our panels pretty well.

Thank you!
In my research, Ive also found that drones are being used to clean solar panels. Ive been a drone enthusiast for a while but had no idea they are being used to clean solar panels and even buildings. Have you ever used a drone to clean solar panels with the types of foaming sprays from that link you sent?

You need a lot of water to spray a decent array, this would mean quite a powerful drone, or a lot of back and forth.

I am sure it would be fun, but probably not very practical, unless your roof is completely out of reach of a hose.

I just found this article about window cleaning with a drone. They are talking about spot free window cleaning(im assuming isnt much different from solar panel glass). They are using reverse osmosis and deionization, which sounds a lot more eco friendly than the chemicals in that "top 5" article. This is crazy. Drones look like they are going to be everywhere pretty soon.

I would again remind that string systems may operate at a very lethal
400VDC, not good to mix with water. My snow pusher is from a multi
section plastic flag pole.

Here tree sap did manage to degrade 3 panels of a 12 panel string,
limiting its output. The only way I found to fix it (descibed in another
thread) was to remove each panel and scrape it off with a razor blade.
Swap done under night lights, I had spare panels. This completely
restored them, time will tell if the outer coating was damaged in the
process. Bruce Roe
