We’ve cleaned over a million panels. If you mentioned you were pressure washing them to the O an M client, you’d be laughed at and refused work.
You may get away with it on the odd little job, but seriously, it’s not the approved method by anyone. As these panels get older, more issues are showing up generally. I wouldn’t want to be in a position where we’ve invalidated warranties. It’d be game over.
Even the brush they use on tractors has had rigorous testing to ensure there’s no damage over time. Can’t just pitch up and blast them, although I’m sure it’d be the quickest way sometimes.
At last someone who knows what they are talking about 😂😂😂 there are far to many cowboys taking short cuts and causing damage , as I said earlier a big firm from up the line was made bankrupt by the owners of the array that fought fire it cost several million to replace the units and list production over several weeks the parts had to come from Switzerland.
