  1. Maybe it was 180m actually on reflection. Highest quote was 28K I shopped around a lot.
  2. What was they thinking. So much money thrown at that.
  3. I have just completed my barn conversion which is in open countryside. My water and electricity connection are 1km away and my internet I get over mobile network (it’s very good BTW). I would get just some quotes from local water boring companies, they will know the depths needed to hit to get to the water table. It was around 280m where I live and I was looking at about 15k cost. However the electricity was a bigger headache having to deal with the DNO. Getting access across private land is not big deal really was you have to get leeway’s - it’s just takes a very long time to deal with land owners. In the end I didn’t go with the bore hole as I just layer a pipe in the same trench as the electricity cable I bought across the 1km distance if you budget 30 to 40k for services you probably won’t be far off..
  4. 3g reduces solar gain a little - good in summer , not so in winter. We have very large 3g south facing windows. Its get very very hot if we don't open and let the breeze blow through. It sounds like externally you cannot do much in terms of planning as solar shading from outside is the best and cheapest option by far. It's super common on the mediterain. Google images "brise soleil" for examples. You need to go with small /limit your south facing windows - this will help with summer heating and keep you warm in the winter
  5. We thought about these but decided against them because at some point one will break and thus ruin the whole window.
  6. ah yes I do kind of agree with you on that. I’m not sure with vertical the canning will go. My roof is only 19degree pitch so gravity is basically making it flat again.
  7. Not convinced about what? more info : https://sheffieldmetals.com/learning-center/what-is-oil-canning/
  8. It does this as it comes off the roll. My roof had some but it’s starting to disappear now a year later as the metal settles. I think to will completely go by this time next year .
  9. My house is a barn conversion in open countryside done via Q planning. If there outside the development boundary (most likely) this will be the only way you will get planning. The checkbox's for class Q conversion are quite simple but they are strict. it has to be former farm usage (you will need proof - a letter from the previous owner should suffice). I think you biggest issue will be getting a structural engineer report to say that the structural sound and can 'take a building' - LA can be strict on this definition. You have to build within the envelope of the existing building FYI - you cannot go outside. You'll need a contamination report and then deal with anything it finds. Check how much Amps the electricity connection is (are all the barns sharing it) as that will cost to upgrade for the DNO. Treatment plant for sewage is not expensive really in the scheme of things. Cost/m2 will be more than a new build as you will have to work around the existing structure all the time and this will cost in terms of time and many things will need to be made to fit. Obviously you\ll need to get rid of the asbestosis - there are companies that take the p**s with pricing. Shop around a lot. We had quotes up to 10K (it cost us 1.2K). Talk to a local planning consultant - money worth spending IMO if you are serious.
  10. i don’ t have a thermal camera unfortunately. It’s a weird one for sure.
  11. So been looking into this more. I have 2 strings of 9x325W panels connected to the inverter. However each string is mostly only generating 70V unless it's really sunny . Looking at the VI curves for the panels they should be generating around 300V per string even with very little light: So I should be having around 300V per string which I'm a long way off. Here is what I'm getting for example: You can see the voltage sits around 70V most of the day. My inverter has a min feed-in voltage of 80V so won't even be generating anything. Note there is also the weird voltage spike at the end of the day - I can only put that down to the voltage potential across the string as the amps drops down/up from zero. Does anyone have any idea? Something I notice is when the voltage is low the realtime Amps seems to oscillate between 3A and zero between the 2 strings backwards and forwards, like a sin wave. So one will be 3A and the other 0A, then both 1.5A and then 0A and 3A over the course of say 6 seconds. Some other days:
  12. I only made 1.1kw today . norfolk.
  13. Yes it’s a single inverter - fronius primo 5.0 I don’t think there was any ‘design’ - materials was just supplied as a system.
