Would it be best practice to perform an earth continuity test, before servicing pv modules?

Calling SS, or has he done one again?
-
Or phrased another way.
Is it unprofessional to clean solar panels without first completing a continuity test, to confirm the array is safe?
-

How would you go about that then?
-
Ss will tell you
You need to pay him first though!!!!
-
Fit an RCD circuit breaker between your pole and the panel.

Much prefer your sarky posts than the useful ones, Slacky (or whatever your username is nowadays, Matt)

Access the inverter and plug a meter in. I'm pretty sure we should be doing this. As these arrays age, the risks are higher and I'm not sure gloves and wellies are the best way to deal with a potential hazard.
-
Don't think that's a window cleaners job do you? Do you measure your domestic customers output. Where do you think the shock would come from, the panel surface or the wiring? Each panel would only produce a certain amount of power, you'd probably have to rearrange the wiring to get a shock from multiple panels and then cut through it.
-
Perhaps not a window cleaners job but a solar panel cleaners? I like to look at the read out on the inverter before and after, to see the increase.
-
What's the difference between a window cleaner and a solar panel cleaner? The second one has bought a tee shirt and paid to go on a course provided by a self taught window cleaner. That's it.
-
The shock could come from anywhere. I've been asked not to clean certain arrays due to rats chewing through cables and other earthing issues. Also seen cracked panels and been told to stay clear by the engineer.
You can be a solar panel cleaner withour any affiliation to Steve.
Perhaps I shouldn't ask about earth tests on a window cleaning forum but as lots of guys here are regularly covering live modules and cables and connectors in water, I think it's pretty relevant. Also the newer panels have micro inverters fitted, has anyone considered that?
-
Whats the difference between our water and rain water?
I dont see sparks flying off solar panels when its raining so i dont see a problem. Am i missing something?
-
When its raining there’s no route to earth, when you’re stood there with a brush in your hand you’re the route to earth.
-
A pair of wellies and a pair of rubber gloves is all you need.
Last time I got in trouble because that's the ONLY thing i wore.
Misread the memo. :(

Perhaps the above illustrates why some sort of safety validation, should take place before window cleaners are let loose on pv.
-
ive had little electric shocks down my right arm when poling solar panels once.dunno what caused it.it was raining at the time as well and i had rubber gloves and rubber soled boots on. ???
i cleaned a customers solar panels last week in the sunshine and no problems.nothing.
could it of just been static electricity?it was an uncomfortable feeling but obviously not life threatening! ;D

-
Ask your customer to switch the solar panels off before you clean them. ;D
-
I clean them at night.
-
I, like I am sure many others have done some research this evening after reading the comments and I cannot find one article about a window cleaner or any sort of cleaner being electrocuted as a result of cleaning solar panels on domestic properties although I am not saying it is not a possibility.
They only carry low voltage unless they are on a large scale and are circuit linked so I still feel confident cleaning them as an add on for existing customers as long as I am wearing rubber gloves and/or boots.
-
Ps, I did find one article written on a farm forum written by solar Steve that claims a window cleaner in the uk spent three weeks in hospital after being electrocuted by solar panels, but then on his Australian advert it claims the man spent six weeks in hospital so I am reluctant to believe this unless Solar Steve lets us know the name of this person and how long he actually spent in hospital.
-
Surprising that steves the only one to know about this ??? You would have thought it would have made national news , Evan if you take all Steve's precautions Ime guessing you could still get a shock as on domestic(don't know about commercial) you cannot isolate the electrical supply from the panels only from the inverter , so the panels are always live , we have cleaned many thousands of them without a problem but you never know what could happen

The fella you're referring to was one of his subbies.
-
Steve offered to pay him 20p per panel instead of the usual 18p.
Everyone in earshot of the conversation was shocked.

by first our water then our pole we are atatched to our water. Electricity then can connect to us.

That's more like the usual, Slacky

funny thing is when we work on solar farms along side the quialfied people that look after them they don't wear any of this rubbish nor do there wear just rubber wellies , all sites we have if you not in steel caps your not on site along with hi vis ect ect
theres so much bull about solar panels and cleaning them you could write a book about it , if you scared about cleaning a ray of solar panels then fully cover any one panel on the ray and it will pull the power down so it wont kill you , its the quickest and simplest way to do it , this is straight out the mouth of the head tec guy we work for and he looks after 73 sites
there no way of stopping a panel from make energy unless its dark , even if there not hooked up to the mians or a full string there still making energy , you just need to use your head , cracked or missed up units need to be left alone

How does that pertain to the fact the original poster got an electrical shock from the panels he was cleaning?
-
Yes Steve, there is lots of mis information on the internet which people should not believe, like your uk and australian websites which says on the UK website that a worker was electrocuted and spent 6 weeks in hospital yet the Australian one dramatises it to 3 months. Who is this man? please send us a link about this poor lad if it did happen, or again should we not believe what we read on the internet?

Unlike our steve to be so slow about replying ?????

Some peeps do have a life you know beyond this forum.
After saying that I suspect ss is waxing his long tash curls and pointy beard as we speak. Bless him.
-
I am still waiting for a response from Steve ???

He's on a plane to Oz visiting electrocution victims in hospital.
-
Ha, nice one. As I suspected, his claim on his website is a complete lie as he has never responded.
People should not be allowed to make claims like that to drum up business. Shame on you Solar Steve, unless of course you can tell us if this man was electrocuted and spent 6 weeks/3 months in hospital!
-
I did some research after my shock last week. It seems it's not uncommon for solar panels to act like a capacitor when wet.
Something to think about.
-
We used to use large hoovers to clean printing machines. Always got shocks off them, you could see the sparks jumping from the suction tube to the machine. Nobody worried about it. Static electricity most likely.

One of my customers got stung by a solar panel job today. For 50 notes from me haha.

I did 12 today for 85 notes. And 16 yesterday for 95.
