  1. Right got you, so your limited to 8kW which is your 2 inverters, but in fact you could actually have 4 inverters at 2kW and your DNO would be fine. I just wondered if you were being told porkies. Micro-inverter installs have 10's maybe even 100's of inverters. You could of course do this entirety off record and just not export. Have they capped you at 8kW then? Which DNO is that? I know some were 5kW per phase. 8kW sounds more generous.
  2. Ask for a price from some IDNO's as well. Not sure about domestic like this but we get prices from Energetics etc - often cheaper. That is commercial, including residential development certainly but not domestic like your application would be - you can also do the dig on your land yourself to save some £££'s - maybe even lay the cable too. It varies from operator to operator. Basically they don't want your generated electricity, it is a pest for them - shocking, pardon the pun, actually because they will be forced in the not too distant future to make it easier for microgeneration connectivitly. I would like to ditch grid connections altogether and suspect I will get there eventually.
  3. In what context,? In general you can have as many as you want.
  4. Like the time I needed 40 tons of hardcore for my garage!
  5. Something most architects don't have unfortunately. One of our projects just now is an apartment complex, architects went and drew a stunning looking building as elevation drawings, some OK looking apartment layouts, but the building could not work, none of the drainage would line up, soil pipes would be dropping into lower floor bedrooms and things, these were no risers, when we told them we needed space for utilities, they said, oh can you not make it work through the fabric of the building... structural columns in the middle of livings rooms and kitchens, clearly didn't understand how a building goes together. Do not get me wrong, I know some brilliant architects, they produce wonderful buildings, but they could go onto a site and build it themselves, that makes the good ones, ones that understand just how materials work together and go together and the makeup of various details. Either they build their own projects at home, or have a house build of their own under their belt or they go to site a lot and pay close attention.
  6. Left hand side of image, just me, or does that course look a bit bendy along the line?
  7. For my self-build I bought I got some Leica kit for site levels, already had a Fluke laser measure (+-0.2mm up to 100m) and some other site marking kit. Or find a local topo company that you can use, build up a relationship with them and you will get a decent price.
  8. Should be no flicker on a good constant voltage LED source as it dims by reducing voltage. Plenty of good 0Hz LED CV supplies.
  9. Could work, however, some considerations: The sleepers sit flat on top of each other, the external wall, would be susceptible to rain sitting/passing in between them and will become quite draughty, it will get worse as they dry out and the gap opens, even sealing it on construction would not last. You need to think about a method to enable water run off - options may include asking a mill to cut the sleepers with a groove and raised "key" section with a diagonal cut to the joint to create a sort of tongue and groove affair. Check the treatment of sleepers, as this is not their intended use they tend to use treatments which are not great for we humans to breath in and touch, just make sure you are not creating a gas chamber for yourself. More of a note this one. How are you going to fix them together at a depth of 200mm - LONG coach bolts? I am sure there must be a cheaper option for you to achieve the same look - I did a fancy garden shed/log store with 100mm block up to 1200mm then a 2x3 frame on top of that, then clad the whole lot in breathable membrane, battens and timber with shoshugibon treatment. I went for vertical 100mm pieces but you could use 1x6 off saw treated for the external, I'd run the lengths through a table saw and cut the corner off to help make the water run out and drip down and out from the above board. Then inside you could buy a suitable internal wood and insulate the frame. Given the volume of timber in a sleeper, it would equate to about 5 pieces of board per sleeper.
  10. Don't think freelance architect for self-builders is for you, with all due respect. A self-builder needs that hands on approach that so many of the veteran self-build architects give. Often they can be found on site, boots on, hard hat on, working with self-builder, contractors and builders alike and getting their hands a bit grubby, offering solutions, being part of it all. £5K - no. Now before you suspect I just think it is too high a price for a package or work and "don't know what goes into it" - I do all my own architectural design and CAD (I am a consulting engineer so in the right industry to self design and draw in CAD), most of what I/we (the firm) do, is make a building work after an architect has done the plans and elevations so I am well placed to pull together a Tender package - unless you are onto the big Grand Design style house, then I don't think there is 5K in the average self-build, unless you will include the SE calcs, drawings and details in that too.
  11. I agree with this, as a consulting engineer I hate when you see "Sales Engineer" on a sales rep's email signature, or some random manufacturer who has trained an 18 year old how to quantify and quote roof coverings as a "design engineer". Everyone in the construction industry now is apparently an engineer. I had someone tell me about their son who was an electrical engineer, I asked who he worked for and didn't recognise the name, I asked where the office was and she oh he is just on sites, I discovered he was an electrician, there is nothing wrong with that, but he was not an electrical engineer.
  12. Try these guys, there is even a array builder tool on the home page. I like these: they work out a good peak power for the ££££'s.
  13. This is where a little EV would be good to consume the energy. Issue is my EV would be away from home during the main sunshine hours 3 days a week. I worked out I could get a little VW EUp on lease for the same money I spend on diesel a month, I considered it, but was put off when I realised I would not get rid of my diesel car, so I would end up paying out more albeit some of my motoring miles would be much cheaper.
