Solar panel cleaning - risk of shock?

[Trent Valley Cleaning]

Hi Guys

I’ve found this thread an interesting one.

I’ve installed solar panels (Domestic/Commercial) I have them on my property and I’m now a window cleaner.

A couple of points 

Solar panels are connected in such a way that the voltages that you are dealing with will kill! 400V DC - 1000V DC

However they should NEVER be installed in such a way that you would get a shock cleaning them.

Solar panels, connectors and inverters are designed to be installed to withstand weather, human contact etc and to be safe.

I personally wouldn’t pay to have my panels cleaned! I earn £300ish a year (Late to the FiT) + the savings. £60 for a clean eats in to benefits.

Dust and normal dirt has little impact on the output of the panels and a heavy shower will sort this. However I’ve seen panels installed under TV aerials for example and one of the panels is covered in bird ****. This will have huge impact on output and would be worth cleaning.

(Solar panel strings are only as good as their weakest panel)

i have the odd window cleaning customer that have their solar panels cleaned periodically(usually once a year).if their near farmers fields they get really dirty over the course of a year or two and of course near aerials due to bird muck....

Cleaned some last week, that were installed under a TV aerial, was a right pig to clean off all of the bird s**t! He said they hadn't been cleaned since they'd been installed 6 years ago.

Lots of soaking was involved but they came up really well. He wants a repeat clean every 6 months, so will ask if it made a difference to the output.

Very surprised @solarpanelcleaningltd didn't get involved in this one.

We’ve cleaned over a million and nobody has had a shock.

That doesn’t mean there’s no risk.

I personally think overhead cables are more of a risk. I could be wrong.
