Does this warrant bringing the installers back to make it right?

Doesn't matter how bad the installation is, was the paper work in order. That's all the MCS are looking for.

Thanks for the replies everyone - the install was done for me. To respond to the 1st 2 replies, the installers gave the best value quote and had nothing bad about them on the web, apart from a concern from another installer (who didn't know I had had another quote from them). Obviously a conflict of interest. Who would you go for? For the little extra, it's worth getting a 3rd party inspection and glad I did.

So it seems that a) they should've used more hooks, b) they shouldn't have removed the tiles and c) that cable should be secured.

Are there regs/guidelines to say this isn't satisfactory? Thanks again for the help, this stuff needs to be secure for decades...

Oh and e.on have accepted the paperwork, so I guess that's OK!

Got a call from a local guy that we quoted for, he went with another company and has now asked me to inspect his install today to see how it was. I've now done that and found a few issues:

1 Only used 12 hooks on a row of 7 panels (no wind calcs provided as far as I know but this is quite a few less than our calcs have ever come up with)

entirely depends on the rails and hooks used. We only eve spec higher strength rails and hooks specifically because we can use less of them, so the install takes less time, so this isn't necessarily an issue.

We also don't do specific wind load calcs for anything other than the worst situations as we've been speccing our rails and brackets to cope with all but the most severe of loadings on all jobs since we started, using the span tables supplied. No point faffing around with different grades of rails and brackets all the time IMO.

We've just had to buy in a bulk order of the stronger version of solarworld's rails from Germany to do this with their kit mind.

This may or may not apply in this case, just saying that there's more than one way to skin a cat on this, and our SE is happy enough with this approach.

2 Cables left dangling on roof between every panel so they'll suffer from abrasion each time the wind blows them.
3 Tile removed where each hook is placed, bottom is flashed with sticky-backed lead replacement but still a gap around the hook for wind-driven snow or rain to penetrate.

Because the scaffolding is coming down tomorrow he's now asked me to give an opinion on whether to ask them to put these issues right before they take it down. My gut feeling is that I would want it put right but then that's just because it falls well short of the standard that we install to. What are thoughts on the forum about his legal right to ask them to correct these issues as his system is producing normally and his roof is not leaking?

simple enough to resolve, and will help focus the installers mind in future. At least they've made a bit of an effort on the tiles though, seen a lot worse.

Best value quote? Really? Or just the cheapest? I wouldn't say any purchase where you feel compelled to call in a professional for a second opinion before
the scaffold has even come down represents good value.


It sounds like you trusted the OP when he came to do your survey & quote as you have called him and asked for his opinion (correct me if I am
wrong, I appreciate this is speculative). Perhaps the lesson here for any future PV customers reading this, is to ask why the company that sounds like they know
what they are on about are slightly more expensive than your cheapest quote.
This might give them the opportunity to explain some of the detail in their methods/workmanship/materials etc that ensures that your installation is spot on
from day one and will remain that way for many, many years.

Those details are what a good installer does to create value. I appreciate this can be difficult for installers to communicate and equally difficult for consumers to know what to ask, but as an industry this needs to happen to avoid stories like this happening so often. I hope you get the required changes made OK and your system gives you a good return

They offered more kit for less money. Everyone who gave me a quote sounded to me like they knew what they were talking about. So all things apparently being equal - and with nothing negative that I could find on the web, and the only concern being from a competitor (who obviously has a vested interest), what to do?

Since the OP raised concerns, and sounded like he knew what he was talking about, I thought it was worth paying a little more to get a second opinion. Because how do I know whether it's right? Maybe neither of them know what they're talking about?

Anyway, the owner of the company came over and had a look and, unsurprisingly, stood by his installation and was very pleased with it. Better the cables are a bit loose than too tight, he said. They've never heard any concerns about leaks with the waterproofing membrane they used - he has it on his own house, he said - and the hooks were more than enough, at the correct spacing of 1 every 1.2m. Everything was in line with relevant standards and guidelines.
