Position of rails/clamps

un....be.....lievable.

I truly hope you get this sorted satisfactorily wstevew. Such lazy-arsed, excuse making, incompetence really does get on my man -----. Proof if any were needed that it's not just the double glazing mob that are responsible for dragging down standards. Keep on to them until it is sorted. Bloody shower.

Why not print off the pictures I posted, and show them to them, with the words, I want mine to look like that.

I showed you the both because the correct bracket was used it did not need grinding as there was a very small gap and the tile sat down properly, and the other needed grinding as it "kicked" the tile up on the joint.

Keep on to them until it is correct, but keep making the tea.

I find it beyond belief that they can come and move the rails and not make the tiles sit flat as they did they first time they installed it.

The installers are about to leave and I await their call.

As always thanks for your help.

The amazing thing is they did look like that until today when they moved the rails.

They have just left now and say they will come back in the morning and remove it all again and grind the tiles out so they sit flush. Seems such a shame, all that hard work and they will have to do it all again just because of cutting a few corners (or not as the case may be).

They did sort out the clamps (I dont even want to think about that if I didn't notice it) and wires, but i guess they will have to do it all again in the morning.

Hopefully they will get there eventually. But it does make me wonder how many other systems...

Proberely many sadly -

regardless of any interpretation of the regs, there is always the proviso of following the manufacturers instructions. SMA say bond, so it needs bonding, as per 7671 with 10mm.
You cannot bond using the earth (CPC) from the T&E (which, at 2.5mm is too small as well, have a look in the SMA manual).
They have used the wrong brackets so anything to overcome that will be a bodge. Trimming will help, but it's not ideal. They should have used a bracket something like these from K2

these ones, wouldn't upload on my previous post!

Moggy,
They did have the tiles sitting flush before, they had ground out the nib at the end of the tile where the brackets were.

Firstly he said he was going to bond to the TWE and I stopped them. They then went and brought a reel of 4mm. and I stopped them and said it should be 10mm (thanks to you guys).

Now their technical guy is supposed to be in contact with SMA because his interpretation of the regs. is that it is not needed. I was just forwarding what SMA stated in response to fixing the 601 events.

 

[wstevew]

Much flatter. I doubt I can demand a specific mounting system, my tiles are not solid they have a kind of hook at the end (im sure you know what i mean).

 

[JulianC]

Did wonder about the size of the bonding but, since this isn't bonding in the traditional BS7671 sense (ie. not extraneous blah blah blah) I am not entirely convinced it has to be 10mm. Nor am I convinced that it hasn't. Any thoughts other than using 10mm 'cos we always do and there's a roll in the van?

yes, that might be pushing your luck a bit! Grinding the tiles is treating the symptom rather than the cause but is better than nothing, as I say, IMHO thats a bodge but will probably do the job.
It's more of an indication that when you look at the whole package, it doesn't look good, and the fact there was a rush on in november may excuse having to compromise on using the ideal kit it doesn't really excuse poor workmanship

can be easily fixed by using Renusol SS hooks.

The Dti guide says 10mm bond.

Probably a similar company to those who are offering 4kwp systems for £6k at the moment, and I wonder why..

 

[wstevew]

Is this join bad too?

I assume that join was previously hidden under the panels, at first today the end clamps were only held on by 2-3mm of rail and I guess that gap is the result of extending the rail out to fit the end clamps.

Now dreading what i am going to find tomorrow when I get home. Im at work and they are comming back to sort out the brackets by taking it all off again and grinding the tiles.

They apparently are waiting for a call from SMA to clarify if they need to bond the array and with what cable regarding the 601 events.
