I guess they are not on mains water.

Yes, along with some very small emergency generators. Gridwatch only shows metered generation, so a lot of domestic PV and micro wind generation is not shown.

Have i got this correct? You are required to collect rain water and use it within you house?

Amazing how much wind energy we produce, until it drops. Presume our batteries are in others, insignificant on this scale

Does anyone ever set these joists up with the required 150mm fall instead of using firing strips?

478L/day is the average potential collection achievable in that location according to Met Office 10yr data with the roof area we have. There is a 10,000L storage tank. 478L/day for max 2 people was only accepted by Public Health Dept. because it is not needed for any outside use (car washing, garden etc) as we have borehole water (un-treatable for household use) for that. The daily in-house use is around maximum 75L/day/person because there are no baths. A bath installation (or two or more) is not a regulation but you are nevertheless required to be able to fill one or more of them at least every day (as apparently now with electric cars) even if they are not present.

This is what actually happened.

I live in the promised land …

Any role for Proclima Tescon Vana tape re this ? I know goddamn nothing, but our architect agreed to its use where ceiling joists went into blockwork - we are not doing airtight/passiv or anything though.

You were lucky , or your merchant is unusual in keeping treated timber covered. It's a good point. Due to receiving 60 large and wet joists which bent so much in drying that 60% were rejected, I looked into the storage. All the merchants keep their treated timber outside and uncovered "because it is treated for outdoor use". This is contrary to their industry guidance but saves warehousing. So do tell your supplier that it is important that it is dry and straight. Maybe get them to set it aside under cover, to bend there rather than on your site. At this time of year they should all be dry. On a positive note, I haven't checked numbers, but most timbers are critical for acceptable deflection before strength. It would be worth reminding the designer of this. Nobody is going to be nervous because your timber is moving up and down a few mm in wind or under snow.

500L/day every day. Even in Scotland that aint happening. Have i missed something here?

Another Building Regulation that unnecessarily works to increase housing costs is the requirement for the water supply being capable of providing profligate quantities of water. My recent 2/3 bed new build in West Scotland was restricted (at completion) to maximum occupancy of 2 people (1 bedroom) because the rainwater collection system installed is deemed unable to provide a supply of at least 250L/day/person throughout the year to more than 2 people.

Spray it on. go and get a forced action sprayer from the hire shop. look at some American YouTube it’s common practice over there.

Didn't say this in you other question on the same subject - I didn't ask, just did it. 14 panel all vertical - like a fence.

Really depends on what you mean by a ground mounted array. Ballast buckets (so almost flat to the ground), 45 degs on a big frame, vertical like a fence. Depending on what you have planned and how it's seen may make a difference on whether you ask or not. Also is this a DIY project or are you paying someone else to do it?

Just for info I used 47 x 220 C24 at 400 centres for my 6M car port. The span tables I looked at said for a flat roof, it was good up to 5.7 metres but not 6. My design has the support pillars inside the 6M width and allowing for further structure my clear span is 5.5 metres, so close to the limit but not over it. My joists arrived straight and dry with no obvious defects and have remained straight.

Hi guys. Understand this thread stopped a while ago but I'm going through something similar. I'm looking at installing 24 ground-mounted panels in the rear garden of my home, also in the Green Belt and a National Landscape. There is a footpath nearby with views to the garden but its significantly far and the view is filtered by mature trees and vegetation. The panels will sit along a wooded backdrop not proudly in the middle of the garden. Just in case youre wondering Im unable to use the roof due to tall trees with shade most of the year. I've found a few local approvals so its possible but am particularly interested in how you managed the planning process? Did you handle the application yourself, and what supporting documents did the council ask for? Was any formal landscape assessment required, particularly regarding visibility from public footpaths(Its eye wateringly expensive)? Would be really interested to hear how you got permission and whether there were any objections along the way. Thanks!

Do you have normal permitted development rights? If so build a shed, or two within PD limits and put them on the roof of that.

Hi everyone, just joined after coming across a few really useful discussions on here. I'm currently planning a ground-mounted solar installation at home, with 24 panels and battery storage in the rear garden. I have tall trees around the house so unable to use the roof in case you're wondering. The main challenge is planning permission as we're in the Green Belt and a National Landscape. I've been researching previous applications and trying to understand what's actually required without spending thousands on consultants and surveys. Looking forward to learning from others who've undertaken similar projects and hopefully sharing my own experience as things progress. Cheers!

There could be support in individual DNOs to relieve particular congestion, and Octopus and Axle may have different coverage in those areas, or due to a grid-wide lack of energy but Octopus is already hedged or participating another way... I don't know. Watch the turn-up and turn-down operations here for a while and you'll get to see/infer all sorts of strange things going on due to constraints, where renewables are generating or not, etc: https://renewables-map.robinhawkes.com/

I'm applying an external liquid applied membrane (bituminous) to the reinforced concrete walls of my new basement. Problem is, there are thousands of very small holes in the otherwise smooth surface finish, presumably tiny air bubbles a few mm across. When I apply the waterproofing, these holes do not fill, I hadn't noticed them before applying the waterproofing as they are very small. I've tried brushing and rolling and nothing will reliably fill them with the paint. What to do? AI suggests a tanking slurry. I am sceptical that this will fill these holes as they seem bigger inside than the part that breaks the surface. I don't really want to switch to a membrane as that seems a lot of work. I'm not too worried about the effectiveness of this layer. I have waterproof concrete which appears to be sound and carries a warranty, the basement is walkout so totally above ground on 2 of the 4 sides, and will have free draining backfill and a land drain, so it is unlikely to see a head of water ever. I'm really only applying the type A because I thought it would be easier to apply it than persuade a "waterproofing designer" that it wasn't required, even though BS8102 does allow just one system in my situation. But if i'm going to the trouble of applying it, it would be nice to do it properly. Can anyone suggest any ideas? It feels like a liquid applied type A is fundamentally unsuited to reinforced concrete, but I think it is very commonly used.

I understand all of what you say but I'm trying to understand why there's a mismatch between the Axle event looking for grid support and the apparent lack of a need for grid support by Octopus. If the grid needed supporting from 7-8 then I'd have thought Octopus would have been pricing to gain that support from their customers such as my mate who had spare battery capacity but didn't export because Octopus didn't price to encourage him to. I appreciate Axle aren't new to this but I'm trying to understand if their seemingly illogical actions are due to them getting support for trialling this concept??

Thanks for the shout Gus Potter, and a good explanation of the deflection side of it. From the timber yard side, two practical things for flanagaj. First, if the C24 that turned up is badly twisted or bowed, photograph it with the grade stamps and send it back. Any decent merchant will swap timber that isn't fit to use, and twisted joists will only get worse as they dry out on a long span. Second, I'd hold off ordering anything bigger or swapping to I joists until the SE has been to site and confirmed the design in writing. 47 x 225 at nearly 6m is well past what the usual span tables show, so whatever she comes back with, ask for the joist size, grade, centres and the deflection limit she's used, plus the fall you'll keep once it's loaded. Then the merchant can quote exactly to that and you're not paying twice. Good luck with the site visit.

@Pocster , if you weren't constantly looking for the Promised Land, it would come to you. Simples

But you also need to look at the bigger picture and the weather - no wind near us at all yesterday, no wind, no wind power, big hole to fill. Your just looking at the tea time expensive period, but other things happen. I've had events 0600-0700, 0800-0900, 1700-1800, 1800-1900, 1900-2000, 2000-2100, 2200-2300. So almost any time of the day. But mostly morning and evening. Axle have been operating quite a while now, they didn't start a couple of months ago.
