just wondering what the opinions are on cleaning rooftop solar panels? some say yes , some say no . Various YouTube videos on how to do it the right or wrong way are also split down the middle. I have been giving mine a hosing from ground level just to get the salt spray off ( live near the beach ) but they remain quite grubby and I haven't noticed any large drops in their output.
the local solar panel cleaning bloke has recently closed his business which tells me he wasn't getting enough work out of the concept , or he was charging too much or his insurance went up again lol
