From a non solar guy, does this look OK

[moggy1968]

here's one I did earlier! Not the best I've ever done but the only photie I've got to hand.
labels went on later before anyone comments!
Middle set of tails go to dedicated CU. Right hand tails (as we look at it) go to main CU

You're brave

or foolish!!!
It was a subbing job

16mm tails absolutely fine.

Connection point not fine for two main reasons:
1. Anything on the supply side of, and including the analogue meter is DNO equipment and we shouldn't be messing with it.
2. When the customer is using the generated electricity onsite, he will be paying for it since it will be passing through the analogue meter.

It should be connected, via Henley blocks between the 'analogue meter' and the 'D/B'

look at your pic, TC. the solar generation has to go through the suppliers meter to get to the CU.

Yes i can see that but but would it or could it just feed the grid if the house was not using any power or even if the house was using power?

I can feel one of my headaches coming on!!!!!!!!!!!!

The PV should be connected after the Incoming meter.
Lets say you are producing 1KW from your PV, and you switch the kettle on which is 3KW, so you would need 2KW from the grid to make the tea, when the kettle has finished, (assuming no base load) then the 1KW would go backwards through the incoming meter back out to the grid, therefore your cup of tea is 1/3 cheaper.

We won't get into meters running backward or RED (reverse energy detected) as that is another long story.

I hope this helps.

yes it will feed the grid and he will be paid for that.

But the customer will not benefit from his own generation eg: his electricity bills will stay exactly the same instead of reducing.

Did you get the installers details? (should be displayed onsite)

So in the scenario i have posted and the scenario you have posted what would happen?

No but going back tomorrow.

Just to add to my problems, what do i put on my EICR?

 

[moggy1968]

The way it looks to me (and I stand to be corrected on this) the PV is feeding into the incoming side of the main meter, so, not only will the customer not get the benefit of electricity he is using, he'll be charged for everything he generates!

whatever the ins and outs of useage/generation are though, it's just wrong and needs to be changed.
The correct order is as per my photo above.

Then ask to see commissioning pack if you cant find the company's name displayed.

That is a crap install and needs following up.

 

[telectrix]

but, TC, the housae power from grid and from his own solar panels is going through the suppliers meter, so he's paying charges on the meter for what he is generating on his roof.

Yep but that will not effect his bill. His bill will remain the same as it was prior to having solar.

 

[moggy1968]

yes, it will only have electricity he is using pass through it. the excess will go off to the grid so I'm not right in saying he will be charged for everything he generates. As you say, just no reduction in his bill!
