From a non solar guy, does this look OK

[Top Cat]

And this is the problem, I do not know telectrix, but judging by his posts he is a good electrician and he thinks it looks like coax, so what would joe public make of this? oh it is just old coax, snip, maybe 700v DC that is going to hurt...

As installs go, this is about as bad as you will get, nothing is labeled, connected to supply wrong, all the cables are a mess, (Tower will not get rich from these guys)
The surprising thing is it is working, did anyone notice how much lower the generation meter is to the inverter reading?

Well TC you have your work cut out there...

Trouble is, is that i work for a builder that reports to a surveyor that reports to the owners! Have been told that they will get in touch with the installers but they are the sort of people that will just say "oh you just sort it out"!
Now i know a little less than SFAll about solar, but i know how to clip cables! If i get the job i may be back on here asking for advice! Mind you i don't know how i would come off if i touched it? Got to be a minefield out there if you mess with it and you are not registered. Any thoughts on that?:thinking:

Most of a PV system is not rocket science, this is just very poor workmanship.

What would you say if you saw an electrician rewiring a house to this standard? I am sure that it goes on, but PV is supposed to be a regulated industry, the problem is nobody seems to regulate it.

My opinion here would be that you could tidy up the wires, but you should not alter the wiring where the illegal connection to the supply has been made, you should be MCS accredited for that (for what it is worth), also the system must be labeled up correctly, and I would imagine that you do not have a glovebox full of them in your van.
Whatever you do though, it might be best not to put your name to it, you do not want to end up responsible for this mess.

Turn it off if you are working on it though, AC first then DC, to turn it on DC then AC,
this reduces the DC load so keeps the DC arcing in the switches to a minimum, or just turn it all off at night.

Utterly pathetic. We all make mistakes but this whole install shows an utter lack of effort.

I've said it before and I'll say it again - I'll bet their QMS is top-notch.

But this is what our Government want, "driving down the price of Solar", and this is what you get... total CARP....
Probably an install done for a price, installers working on a price..

It'd class as a dangerous installation in my book, so IMO you're actually obliged to sort it out, being the last electrician in.

Although actually, it does involve the DNO's kit, which we're all not meant to be touching, so technically you probably should be getting the DNO to remove the additional cable from their fuse, then you can install the tails blocks in the right place. I doubt the other company got the DNO to do the work though...

Put it on your eicr inform who you have too then wash your hands of it.

I have masses of solar experience having worked as an installations manager round the country have all the quals you can get but I still dont touch solar in the field now as I am no longer in the industry and hence have no Mcs.

you don't need MCS though to be allowed legally to work on solar, only Part P if it's in a house.

MCS is only for claiming the feed in tariff.

thats why we are looking at these pics

Yes but to rectify this he would require mcs as in my opinion the whole lot needs stripping out and redoing.

Chances are the roof is a mess too.

You don't need MCS to do that, just competency (although you wonder about that sometimes!). Thats why all these subbbies are doing it without MCS. As above, MCS is just to get the fIts. as you aren't materially altering the installation (changing the inverter or panels) you don't need to be MCS to tidy this mess up. If it is rent a roof though you'll need to obtain permission from the owner of the equipment. You would be within your rights to shut it down if you think it's dangerous in it's current condition.

'clipping cable is time consuming you see, so to get the price down lets not bother and bang the job out as quickly as we can, maybe then we can do 2 a day seen as the rates are so bad now'

Thats the way the industry is going I'm afraid, and as long as we keep shooting ourselves in the foot by driving prices down the more this is going to happen.

I've just priced a 4kW job up today. cutting my margins so they are barely above general electrical work, using Yingli panels and an SMA 3600TL I can get it down to £7999.
Thats taking 2 days to do a nice job. clay tiles so we'll need quite a bit of lead. HOuse so we need scaffold. OUtside cable run in plastic conduit.
No way can I get down to the sort of figures mentioned elsewhere on here without compromising things I'm not prepared to compromise on.

Just a thought ... if that meter is actually the landlords, installed as a sub-meter after the suppliers, and the landlord is billing the tenant, it could be in the right place...

No that is supply authority meter.

Still doing the EICR on this. This is what i have put down:-
(1) Solar meter wired incorrectly (wired before not after electricity board meter) Code C3
(2) No warning labels by distribution board or in roof space Code C2
(3) Single insulated cables showing going in to solar meter Code C3
(4) Cables from solar panels left in looped coils in loft and not clipped Code C2
Any thoughts on this? Anyone not seen this post you will need to see pictures on page 2 of post

 

[telectrix]

i might be inclined to downgrade your C2's to C3's as although rough, i can't see a potential danger.

Been struggling with this for a while Tel, have changed those two C2's to C3's backwards and forwards. My reasoning for C2 is with no labeling someone could remove main fuse (God forbid) and the D/B is still live so potentially dangerous. Also cables in loft could be tripped over or cut so potentially dangerous.
