Difficult to say which is best. In performance, REC looks best on paper. But there's not a lot in it.
To be honest, if it were my own house then I'd go for REC, followed by Solarworld, followed by Phono. But I'd be happy with any of them.
Much more important to find a company which knows...
It's a judgement call, I would say.
What is the grid voltage currently? If it is low then you can maybe afford to let the 1% rule slip. You do risk the possibility of problems in the future however if the grid voltage rises.
Unfortunately, as you have probably noticed, the cable size...
I already have. We were actually working on the site at the time carrying out other work. The cable work looks like it's been carried out by a chimpanzee with a sledge hammer.
We went to look at an electrical job on Saturday and to cut a story short, the work they wanted doing simply wasn't feasible. Anyway, having noticed our van, the guy then proceeds to tell us that solar PV just doesn't work and that he is looking at solar thermal instead as it is much better...
I've seen some dodgy things on site over the years, but this is absolutely staggering. To get something so obvious so completely wrong makes you wonder what else he could get wrong.
Environmental issues, enjoyable work, diversifying our business.
It certainly isn't lucrative. In fact, I'm very surprised (and impressed) by firms which focus entirely on PV and still maintain a decent level of work.
I find it puzzling that such a person should actually exist.
And I suppose that is why we get such fundamental mistakes as this.
And this.
10% less does seem high but perhaps not outrageously off. Are the panels clean?
What is the roof covering? Is it bonded? Extraneous?
Is there any reason why the TL inverter needs to be on an RCD? Such as how the array is installed or the route of the AC cable? If not, then what's the issue?
ETA Ah, now that I've read the thread properly, I see what you mean.
Surely getting the DNO out is the right thing to do. If a TNS is...
I notice that some of the posts have been deleted and some of them have been moderated. I've noticed that a lot of negative opinions of Genius mysteriously disappear.
The Sun Lounge is tradesmen only but I personally wouldn't have any issue with you having access, Andy. It is fair to say that your input is pretty much invaluable to the forum.
