Steptoe

That's the stuff, I actually wired the first proper unit they had.

Ye, I've just checked, free delivery over £35 , so easier just to order one myself, now, what else do they have that i don't really need,,,,,,,,,?

It's better that my shitty green Bosch one, I just need to find out when the missus, or her dizzy mate is next going into town.

Oh, I've been waiting for those to come back on offer, My mate has one, cracking for the money, but not worth the original price imo,

But that's because you keep rubbing it off with your wipers, seriously. Bob Heath is actually better, but a helluva lot more expensive, there is other stuff that's really good, but damned if i can remember its name, it's made on the Isle of Man, The only other thing i can think of is "aqua" , very, VERY water repellant, not sure if it's readily available on mainland UK or not though. and again, not the cheapest.

This might be a really stupid question, But, as all your measurements have been designed to a 100mm frame, how will that work now that you are adding an extra 40mm everywhere?

Oh, There's an idea, Get a narrowboat and say you're waiting for the great flood that will happen,! Would work really well if you live in some parts of Co Antrim, My missus (an English girl) couldn't believe the amount of holy roller signs there were, " THE END IS NIGH"

I've always just used oversized worms/pigtails/whatever their name is, But, I've never had to hang anything more than maybe 15kg , You get a few different sizes of them, so obviously for a light a smaller one would do, but something like a sat dish is going to need maybe a 2 or 3" one. For a new build, I'd prefer Dave's idea though.

Looking good, But what have you done with the rockwool where the down lights and transformers are,?

Yep, Its stupid, Its a shed, it can be took apart, that's the whole point of making it in panels,,,,,,

The 50mm to the island is vertical off the swept T , the 45 just has a short piece coming up at an angle to allow for rodding in future if required. In my understanding, which is quite a good idea imo..

But the roof makes 3 sections,?

I'd agree, having done hundreds of installs, I've fitted mostly SMA or Fronius at the better end, and loads of other cheaper stuff for jobs on a budget, but haven't done much domestic PV for maybe 3 or 4 years now, mostly only larger commercial or farms recently, so haven't felt qualified to comment, whereas Binky does these on a weekly basis so is up to speed with the latest kit.

The heights can be disregarded for and accessory that is for a specific purpose, ie, a wall mounted TV, high level fan, etc, So in your case put it wherever you want, but 100mm film a horizontal surface is a regarded minimum, (but not an absolute rule) for accessibility for maintenance. Socket outlets must be a minimum 100mm above a horizontal surface to allow for the flex ,

Glad you got it rescued, My mate got his whole floor done with a power float, it looks amazing, That's his finished surface, it's like glass/marble/whatever you want to describe it as, I don't suppose a garage needs that detail,

That's why you get professionals that know just when to "hit" it

By business does not have to mean ( in law) in the course of a business activity, it can also mean in the course of carrying out business, which in the case of a SC would be applicable. I think this is a case of trying to avoid a legal obligation, Only an opinion though from the point of someone that runs a successful Ltd company, I'm sure a lot of others without that legal responsibility will try and find a way to shirk their legal responsibilities to try and save 0.05% from their house build.

Section 7 (b) If the architect or whoever specifically defaults to not being the PC then it automatically becomes the role of the client, and , tbh, I'd be very surprised if any architect doesn't have this in their T&Cs So, its would still make the self builder the PC, I really fail to understand why anyone that is contracting various trades on a site cannot see themselves as the Principle Contractor, On the other hand, if you contract the works to a builder who then obtains the services of others, then yes, that would mitigate you of the PC responsibilities,

The contractor is you, unless you have specifically appointed a principle contractor, that's the whole point, Most self builders don't do that, as they want to contract each trade individually.

By being a self builder undertaking the role of contracting the various trades by yourself it is a given that you have assumed competence of a degree to manage the works, thereby you are appointing yourself competent. I really fail to see how any self builder can contemplate spending 50 100 200 £K and more even and fail to see the advantage of spending 5 or 10K in obtaining professional services for certain stuff beyond their knowledge, it's part of the reason i try and distance myself from domestic works, most domestic think they know better until they get into a hole, only then do they want to pay for professional help for things they can't materially see. It was an HSE case actually, householder settled out of court, but still got a massive fine for allowing works to carry on with no professional competence.

But, that by default makes you PC, and if you don't have the expertise and/or knowledge to carry out this then you outsource it, CDM2015 is pretty clear cut on this, i don't know why it's even being argued about. You either engage a PC or you take the role on yourself, with all the required responsibility, what's so hard to understand,? EDIT : yes, I've been to court with a similar incident just last year where a householder was responsible for not ensuring the electrics were 'dead' before a groundworkers cut through a cable, even though their were electricians on site, it wasn't part of their RA as they weren't doing anything with the existing outbuildings, so it fell on the client, ie: householder

It may seem that way in principle, But getting the exact same panel in 5 (or 10) years time may be an issue, and getting it made water tight, well, let's not even go there.

It's a bit of how manufacturers get you to keep buying their stuff, same batteries, Even Makita have got like dewalt now tho by having diy versions of their tools, anyone using any apple products automatically gives apple the right to take any and all of their information and use it in any way they see fit.

Just to add, has anyone considered the degradation of the efficiency of the panels,? Obviously an in roof system will be a lot more expensive to replace than an on roof system. In my professional opinion, if your payback is >10years, then it's not worthwhile, any solar PV system i have installed has generally a payback of 6-7years max to be viable, otherwise it's just not worth it when maintenance costs are taken into account.

A general rule of thumb is 8x diameter So for a 60mm duct you'd have a 20" radius
