I cleaned up solar panels, how much extra production I got?

Your videos are excellent. You an asset to the DIY and expirmental community

Thanks for this video. It confirmed what I already thought. I live in socal and only see a small production benefit after the first rain of winter.

Damn, didn't expect change to be this miserable. Thank you for the research!

Thanks for the video. Do you have a comparison of a clean panel next to a dirty one on same day? Checking consecutive dates (before June 21) can be attributed to longer days - which can easily account for 3% (or at least part of it)

1:16 you can see data 3 days apart

How do you find out the "coefficient of 1.7" that you used? Does it have units of [h/year]? Your data suggest that if the owner can clean them is a no-brainer. If you have to pay for it, then It migth not be appropriate

I'm in California, we have mostly sunny days. I did calculate this coefficient using historic data from multiple solar arrays.

What is the production for the clean panel vs the dirty panel next to it on the same day? Did I miss this comparison?

[@jasonbroom7147]

If you pause the video and look closely, you can see this information. The bottom line is still the same...cleaning solar panels just doesn't make that much of a difference.

How long they stay clean also matters. It won't be 3 years. When I clean mine I'm lucky if the production boost lasts ~2 weeks. So you'd need to clean them every ~2 weeks :(

[@vicietor]

would the difference be bigger in countries with less sun?

[@SolarEngineering]

i don't know..
