Run it though PVGIS and then see if it is worth it.

Who remembers, back in the 70s, those UV 'black lights'. They showed up all sorts of things. For years, I wondered where the blackness in Guinness went. Then, one morning, I looked at my girlfriend, and realised that it went under the eyes. Mirrors are dishonest bastards, and they don't even reverse an image properly.

There is a bit about installing data cables here. As far as I know they do not have to be in a safe zone, though newer PoE may be different. https://professional-electrician.com/technical/networking-data-cables-in-compliance-with-bs-7671-requirements-niceic/

Too right, The Queensway Club was one of the best there was in West London. How times have changed. This guy helped me get my rocks off (sauna ones) at the Lingfield Club in Swiss Cottaging.

Yes, I do.

What size (kWp) PV system are you thinking of installing? When divided by 17 flats, and accounting for utilisation (50%), is it going to be a useful saving.

If someone changes a 'practice', i.e. drive a manual car after decades of automatics, then some retraining is needed. It is the same with heating systems. I went from gas and radiators, in an old Victorian house, to storage heaters in a more modern TF house. First winter I had an over hot home, and large bills. Some tweaks and now I have a stable 20°C home and small bills. Just takes some real research (look that the science, not the brochure) and it will all make sense. Also. Temperature is not energy.

Frederick Winslow Taylor sorted this out about 1900, which I think is 7PM

It is in Scotland. They still celebrate a sunny day. Nearly time for 17h 55m and the all important 47s for the sun show itself, and peaking at 56° above the horizon. (I get 63° but only 16h 23m and 26s of daylight)

Apart from the looks, is there any performance advantage in having bifacial?

I am owed £7k already.

Free to Use.txt Yes I have attacked two file. One is free to use, anyone can do what they like with it, it is called Free to Use.DWG, but due to the restriction on this site I have had to rename it to Free to Use.txt The other is called Architect Image.pdf, that is £1000 per user.

Maybe because they are the paying customer.

Got to go on a car journey for the next hour or so, do a little sketch of what you want and I can ponder it. I think you can claim a SEG payment that is unaffected by the main supplier (could with FiT) and to a different person. That way it would just be wired in after the individual meters but before the consumer/into units. Any generation will find it way to the nearest load.

Why not just wire in an off grid system and then run separate DC cables to small inverters in each flat. If too much much power is drawn the small inverters should shut down. But would it not be easier to wire in a grid tied to the main feed and then just sub meter the PV contribution to each flat.

PV technology has not changed in 40 years. Only gradually improving module efficiency and large price decreased have happened. When governments created long-term contracts, they usually look to be poor value, so you are right when you say that you would not want to be negotiating them. The original FiTs was classic, people are still whining that they cannot get 41p/kWh, but fail to remember that a 4 kWp system could cost £20k+. Same system can be self installed for less than a fifth of that now.

Ask the architect/designer how much they want for the rights to the design. Then negotiate.

As a general rule, don't worry about the least significant number for the thermal performance. For floors that are screed/cast over, the compression strength is really the important bit. Two things happen when insulation is compressed, the thickness reduces and the conductivity increases. Ask yourself if you really want insulation of unknown or variable quantity where it can not be rectified. As a general note, all too often people ask similar question about floor insulation, nearly always a sensible amount has not been specified, especially when UFH is used.

I am bored of this, may come back when it gets to page 27.

That is the way I understand it. You should be able to get a better yield and newer PV modules are more efficient at lower light levels and if the right inverter is chosen, then that can be taken advantage of. Generally, natural daylight follows an inverse square law. So you get a lot of sub 100 W.m-2 light, then half that between 100 and 200 W.m-2, half again between 200 and 300 W.m-1 and so forth. Very little at the greater than 700 W.m-2.

I was at a meeting, 20 years ago, about teenage pregnancies, I felt I was not contributing enough.
