Hi allLooks like good old Crusty lichen to me
a customer asked me about cleaning his solar panels, I have cleaned a few, using Gardner wfp and a supreme soft flocked brush because its extra gentle, but when I had a look at his solar panels, they looked very challenging to clean, anyone know what is on his panels and the best way to clear it off safely ?
many thanks in advance any replies
regards Michael
Not noticed this to be honest and we do a lot with liken on them , scrape , treat scrub rinse they look like new in fact I have a house to do in a few weeks time that’s bad will , have an extra close look .Not sure you will get a full res image, but have a zoom in on the closest panel. You can see the cloudy spots left behind, only visible when the panel has dried.

You can see the cloudy spots left behind, only visible when the panel has dried.I see something on the centre panel and the one on the left if the picture but is that a reflection of what ? When I first joined this forum everyone used to talk about how easy it was to clean solars. 5 minute job that you can charge top dollar for. Recently I've had a load of this type of clean. We had a fella with us with over 30 years experience. He would hop up a ladder, scrape them, do them by hand etc. What a ball ache. I had a flat fee of £60 for up to 10 panels, then £5 per panel. Not sure I ever want to clean solars again. The standard advice is no chemicals and no abrasive tools to be used.
I used only hot water & elbow grease for these, no chems.
Most likely as @tench comment, the AR coating has been damaged.
I may take a punt on the chemitek lichen removal agent. It seems pretty new to market though as no mention of it on the forums etc.
Most likely snake oil, but who knows! If it makes it a bit easier...
I see something on the centre panel and the one on the left if the picture but is that a reflection of what ?It's so hard to see when you take a picture.
It's so hard to see when you take a picture.Still can’t see it , if it’s that small it won’t affect the output anyway
The panels on the left are reflecting the clouds
If you zoom in on the first cell you can see in it's entirety at the bottom of the image, you can just see a hazy spot, near the bottom left corner of the cell, about the size of a 5p coin.
Still can’t see it , if it’s that small it wi t affect the output anywayI'll get another one and post it in the future.
I'll get another one and post it in the future.Ime not sure about any coating being on panels , we used to clean tens of thousands of them for green gen uk one of the biggest installers in the country , and they said that it was virtually impossible to damage the surface we regularly scrape them with metal scrapers to remove liken they knew this and were fine with it , they were more concerned with using harsh chemicals and damaging the aluminium frames around the glass panels
I highly doubt it would affect the output, more aesthetics to be honest. When you look up from ground level at the panels that have dried, and you can see a bit of patchiness.
Just wondered if anyone else had other ideas as to what it was or if it is what I already think, the AR coating is damaged.

So as long as you keep the scrapers away from the seal you should be fine. The odd slight scratch is going to be insignificant compared to the lichen that was there.
