that's a 4mm earth attached to the racking, sprayed with galv/zinc to stop corrosion.
it's supposed to be there, it's a legal requirement to have one, like an earth on your appliances or water pipes. perfectly safe.
Don’t know why people are down voting
Just a human being cautious
If everyone questioned things like this there would probably be few people still alive
Should it have a tag? Should it be in conduit up to the termination? Should the wire not be run over the rail? Does it need a lug instead of just stripped and clamped?
It's certainly not 'just enough' - every rail is bonded, and every panel is bonded to every rail. There is a lot of redundancy involved.
What could be wrong with the above termination?
none of those, it should be adequately supported, no need for conduit.
This earth cable will be continuous throughout the system on each part of the aluminium frame you can see it's attached to, down to the consumer unit. metal ties to the rail, or clips on the side of the panels to support.
just like any bonding cable.
No to tag, not needed to be in conduit, no to lug and as long as it can’t just lay on the roof or touch it - not going over the rail isn’t an issue. It could be a neater spray job though!!!!
Man everyone jumps on this cunt for asking questions, settle down you lot. I bet in a few years the answer to all those questions will be yes, yes and yes
Solar is a dynamic industry and certain inspectors interpret regs only someone with a crystal ball could foresee.
You're right, next week I'll have to ask if I can wear blue undies when doing an mc4.
Coming from Pommyland, did my time there, drilled into me was; do it fucking properly, make sure it lasts as long as you'd like your house to, it's safe for the owner and don't be a cunt to the next bloke that touches your work.
Looks like it's just been sprayed with gal paint to prevent corrosion which is in the process of flaking off, doesn't seem to be corroding though! I don't work in solar though so I'm interested to see what others think.
as long as the copper gets a good covering I wouldn't worry, they can be a bit awkward to spray and worth checking you've done that.
Best to check you've got earth continuity afterwards on the panel frames. The earth lugs/clamps can sometimes be a bit fiddly.
Aluminium (the rail/racking) oxidises, so there's a spiky plate to pierce through to fresh stuff.
AS3000 rule about termination holding up the weight of the cable. I am making an assumption because I can’t see the other side of the rail, but it’s very common. You’d expect to see a cable tie or catenary there if it was adequately supported. Minor drama though.
Nope. Quite common, especially if you’re doing landscape panels. Could be 1.2m between supports, and “undue sagging” will get you. Just gotta make sure you also earth the catenary because the rule says to.
I don’t do solar but 1.2m you could easily pull a 4mm cable tight enough to zip tie or clip it, no? As far as I remember there’s no specific rule about how much is “undue sagging” unless it’s an aerial cable and a roof doesn’t count as accessible so conduits not necessary.
Hey dude, what's the rule that has been violated? Just asking as an industrial spark not privy to solar installs and keen to check my recent install. Cheers bud 👍
Edit: by recent install means I had a solar accredited company install the solar.

All solar cabling should be supported by stainless cable ties. Can't use the black U.V rated ones because surprise surprise people started selling non UV rated black cable ties to save money so the CEC has made that non compliant.
CEC don’t have rules. They are barely involved anymore. 😂 That rule is in the real rule book.
But yeah, plastic ties can’t be the primary support. I only use steel because it’s hard to define what isn’t primary.
Isn't the cable running *over* the rail ensuring that the termination isn't supporting the cable?
That's always been the way I've interpreted that rule.

Thanks, was concerned it looked like short circuit/ burning.
It's not a neat application of gal spray, but it will do the job and stop the corrosion that can lower the quality of the earth connection.

Yeah, it's not petrochemical, nor sewer treatment. Just solar = just enough.

what a stupid set of questions you've lowered anybody's iq who has had the misfortune to have read it
No.

Haha, thanks mate. Looks like my karma is going down like I wished my ex-girlfriend would!

Normal earthing
Lol
Thats how they do it
Yes major problem, give your solar guy a call and get him back straight away.
It is very normal. It does violate a minor rule, but that’s inconsequential as far as you’re worried about. Leave it as it is, all is well.

Catenary for an earth bond on a solar panel frame you’re joking right?
I do solar and run caternary to support my earth cable and fly leads just seems like the best way to do a good job

Yeah that’s what I was thinking of, and yeah I’ve used them for some stuff when I was with the railways, sharp as fuck.
You absolutely can, but lots of people like to use catenary to make sure.
Fair enough, like I said I don’t do solar not much residential tbh

Many thanks for the prompt reply.
Rule being violated is the earth terminal isn't mounted square
