Its not that I don’t trust myself with high pressure. I dont trust the method for cleaning solar panels. Theyre not designed to be cleaned that way.
I would dispute your theory that a domestic wouldnt fight it. If you write off £10,000 of solar panels, their electricity generation and potentially burn their house down through your negligence (which is what it is; check out the manufacturers cleaning instructions and recommendations) you’re for the high jump.
Slacky, your probably one of those people that walks round wrapped in cotton wool.
I’ve been in this game 12 years, pressure washing all those years as well. Chill. You ain’t gonna damage the panels.
As said, I would happily do it again, having now done it.
We can agree to disagree. As someone who has now actually done it, I can safely say, it’s extremely unlikely you’ll cause any damage, it’s also unlikely you’d need to use high pressure in the first place. In this instance, it was the only way.
I leave with you with this. The actual LPM needed isn’t much, you just need that turbo nozzle to create a concentrated pressure onto the lichen. It’s a very different technique to pressure washing a patio etc etc.
You have far less spray because you turn the unloader valve down such that the LPM is around 8-9lpm. Rather than 21lpm i would usually run. You’re also running at circa 1000psi, rather than 3000 psi.
All of the above means that the chance of damage is almost zero, and in my case, it was zero.
The panel itself is extremely tough, and there is absolutely no way you’d damage the panel. The single only issue is water ingress. You remove that issue by reducing the flow and pressure.
It’s very effective, and very safe in that instance.
Heck, if it were that dangerous, how on earth did Darren clean a massive solar farm that way with no issue? Could it be because your massively over thinking it, and have never tried it to actually know?
