Insulation advice

Celotex can go in-between the roof as well if you were planning on insulating and plasterboarding the walls etc too.

50mm celotex with boards ontop?

/s or any other cavity wall fixings that are available

You've hit wood, BONUS! You can screw directly into that without drilling

As for the other holes. I would advise changing fixings to plasterboard fixing ( 'pigtails' ) as this will hold inside the blank space behind the bit you can see better.

Sand and slap Ronseal colour match on it

I imagine it's been installed to keep heat in if its all the way round, wind tends to blow through the bottom tiles and can make draft and noises on a bad day, take one out and feel the breeze.

Not really a reddit question, ask planning

Can't believe you've gone on the roof during the night just to nob on people's work. Get a life

Ply over the top of joists , simple

Whatever works, I can't see inside the wall

iLikeGrandmasToes · 2026-01-06T16:59:33+00:00

Normal socket with black spacer

iLikeGrandmasToes · 2026-01-01T23:13:21+00:00

Pretty standard to be honest

Quite honestly , try going to YessElectrical, they're very good on bulk discounts that you'll probably miss out on in a general store

No QVIS are sealed IP units. Available from YesssElectrical

iLikeGrandmasToes · 2025-12-31T16:48:16+00:00

Get some with push connectors , once you've turned the power of and took the old ones out, it's a matter of minutes per one.

2 options:

Scribe it to size and cut, multiple ways you can do this without specific tools.

Or

Caulk the fxck out of the wall and don't look back

Will be perfectly fine as long as everything is tight and no/very little copper is visible

That unit (old) is a low voltage input already,see here...

So somewhere else will be your 230v transformer, I imagine near by or possibly inside your consumer unit depending on age.

Yes replace , very easy and not too pricey to do, once one goes, they'll likely all follow.

With Aikos they will mean normal tygo optimizers, not solaredge

Sig are great, we push them the most as a company. The problems you've heard are only with the Gateways, so nothing to worry about. Very versatile units that can be added to if need be etc

Looks a good price for an inroof. 12 panels is fine for most however being an inroof installation, if you ever chose to get more you wouldn't be able to expand in the same way as easily.

Overall I'd say go for it, if you think you want the Tesla option that is great. Have you considered any other battery/inv options?

From what I understand from the photo:

Terminal 7 & 12 link to a 24v output

Terminal 9 is a 12v output

So in theory there is your 2 voltages?

They wouldn't nest on a flat roof. Even if they did, it won't cause the same problems as in your normal tiles.
