Ok let's clear the air once and for all.

These things are solid glass Previous chap spoke about tree sap so if there's any harder deposits and you want to give it a little wash down with some fairy liquid or flash  or something a little stronger etc given that they are extremely rigid glass surely many have done this ?.
Has anyone ever actually heard of solar panels breaking down after cleaning them with any solution.

A little bit of fairy isn’t going to harm them, they are designed to withstand the elements/bird crap etc.

We have cleaned tens of thousands of  panels never had a problem , Ime sure you could safely clean them with all the chemical cleaners out there including hypo ,but and it’s a big but if you do it will invalidate the warrantee if there is a problem and if you are working for the manufacturers and   installers like we were ,we would then be held responsible for replacement costs , you don’t want that when cleaning solar farms . Use what you want in them you will probably get away with it ,but just be aware you could find yourself with a very expensive bill if it goes pair shaped

Thank you for this. . Generally I don't think anyone has heard of a panel breaking down ever after cleaning.but Good guidelines to follow here.

Fairy liquid isn’t going to break down a solar panel, you have no worries there.

Splash, I’ve also thought about softwashing them, and then rinsing off with pure, but i think hypo is a bit too risky. Shame, as that would make cleaning them a doddle.

I think what splash is trying to say is he's confirming they're extremely rigid. And you could probably get away with using anything however following the guidelines would be best.
These panels have been around for many years and I'm certain people have used all sorts of stuff on them by now we would have heard at least one Horror Story nothing has come out.

The latest black smooth panels have a surface coating that is very easily damaged we have a customer that has 1000 of them on the roof of a commercial building and a fair bit of seagull poo on them every panel is damaged and they were only fitted in January this year , we met with the installers and cleaned a few using just pure water but the whole lot are going to have to be replaced the installers are now saying they will have to be cleaned every 2-3 months totally unaffordable option for the building owners due to the cost involved. They also said don’t use any chemicals whatsoever on there panels as the film is very delicate I said to the guy they arnt fit for purpose he said off the record I agree with you !

After doing many experiments with different degreasers, I have found out it all depends on the temperature of pure. The hotter the pure the easier it is to clean. Recently I had to clean a massive sign under a public path to enter the building. I could only use hot pure in case it dripped on a member of the public. My heater was on all day and my pure was very hot. They all laughed saying it will take hours. After 15 minutes I was finished and smiled back at the staff. The only reason the alga and dirt came off was because I sprayed hot pure on the full sign before I even scrubbed it. When I went back to the start again increasing pump speed, the sign was sweating and a light scrub and everything came off.

When water is heated, its molecules move faster due to the high level of kinetic energy in them. Higher kinetic energy makes hot water an effective solvent. The higher the kinetic energy in molecules, the faster they will agitate the surfactants. This makes the stains come off much easily.

I've heard folk who have solar panels fitted are told to get them cleaned every 6 months, good for us.
