Was quoted 9700 fitted for 10kwh dc coupled with a new hybrid inverter inc 20% vat (not a generating install)
Or 9500 for 2x5kwh ac coupled system using my existing inverter.
Last week.
8 weeks eta from placing of order.
UPS wiring separate - possibly 900-1200 extra. The system isn’t g99 compliant so needs extra bits to bring it to regs.
those of you with batterys installed - what tarrifs are you on ..... what do you pay.
The retailer mentioned having to fight for economy 7 and have dual meters to make it worth while ? - is that still a thing if your on a smets 2 smart meter i thought that was the whole point to allow variable rate billing ?
Been chatting with wife tonight.
We are going ahead with puredrive 10kwh battery system c~10k hedging our energy while we can.
Can't decide on ac or DC.
Both have their merits.
*Full disclosure I already have a 4.14kwh array on the roof via. Solis 3.6 5g inverter.
*
25 years is a long time..... I expect I'll be upgrading /adding more solar over time.
An AC system is standalone. And just does it's thing....I can run many strings /inverters/ etc and the battery continues doing it's thing.
A DC system with a 3.6 solis inverter means I'm changing my inverter - at three times the cost of the stand alone solar inverter.....should I want to upgrade my array at all. (Happy to be corrected on this as obviously if I do this I have. Spare Solis 5g inverter....
Currently I think I want to apply for a DNO next year and take advantage of my unobstructed rear aspect and fit another 4kwh array over there and have a split north/south array. To extend input.
Hive mind thoughts?
Hive mind thoughts?
Do you get a FIT payment for your existing array? If so, would a DC battery affect it? If you added extra panels you would lose the FIT, but I don't know if it's a problem otherwise.
Do you want to use the battery for backup power if the mains goes off? That means you need a contactor to disconnect the house from the mains.
I'm interested in your mention of a North/South array - I assume that means some panels not facing in the optimum direction. I have panels facing SE, but the NW side of the roof does get oblique sun in the afternoons and I've thought about extra panels there.
No fit
Do you want to use the battery for backup power if the mains goes off? That means you need a contactor to disconnect the house from the mains.
Puredrive Battery's not g99 compliant.
About 900 quids worth of extra wiring and a contactor as you say to fit a ups style back up system for lighting circuits and a circuit ring.
Currently I have a directly south facing array
I would like to add extra panels to either catch the morning sun (due east) or evening sun north west ish to extend the solar day.
Need to play with the simulator though to work out which is best....
I don't need more peak power but a longer duration would be beneficial.
@trail_rat I’m in a similar situation here with 4.65kw on a south west facing roof, and looking to take advantage of the morning sun by adding a couple of 385W panels on the north east facing slope. At this time of year I reckon there’s a minimum of 3 hours where they will produce energy, although come October tailing off to near 0. What is this simulator you speak of?
Given my export stats I really can’t justify the extra expense of a battery*, so I’m interested as to how much energy you estimate will be stored?
*I think we both use iboost style function for hw tank & the odd rad, which is akin to energy storage.
Also, given the north/south panels aren’t producing energy at the same time and the standard Solis inverter is limited to 3.65 anyway, why bother with DNO application at all? Averaging load during the day is surely the best/cheapest possible solution.
Whilst I don’t want to sound negative re batteries, I just don’t think the cost/benefit is quite there yet (for us). I don’t think it’ll be too long before EV technologies enables all vehicles to act as overnight storage. I’m also assuming/hoping the relative cost of EV’s reduces over time.
Whilst I don’t want to sound negative re batteries, I just don’t think the cost/benefit is quite there yet (for us)
Have you done the hard maths over the life span ?
For me based on the last year's generation ...... Moving from 30% utilisation to an 80-85% utilisation gives me a break even of 10 years at current prices on the battery alone.
The panels worked out at 6 years and that was pre price rise....
I have a solic yes plumbed into heaters but if I had a battery that would only operate when the battery was maxxed and I was exporting due to where the CT clip is. Bang for buck i should fit a water tank and an immersion but it means replacing a perfectly good boiler as well which seems madness for a one trick pony.
As for using cars as over night storage....that only works if your car is there during the day to charge from the solar.
You can only over supply your inverter to a certain %age. Firing 100% of my front panels.onto the back of the house wouldn't land within that.
Google pvgis. It's pretty much pap on exact for generation month on month for my location.
Need to play with the simulator .... Google pvgis
Thanks, that's useful. Just checked and it reflects my existing installation very accurately.
I cant decide on having panels on the flat root at the back. We are south facing with a flat roof extension. The installer has shown me some padded frames and said they will ballast the frame. I am concerned with leaks or problems with the bitumen felt roof later. The roof was done approx 5-7 years ago and is in a good state. Has anyone had something similar installed?
we are pricing up battery storage for when we get a solar system fitted. we are seriously looking at getting a E car with push pull technology instead of a battery system. For example, the VW Buzz ID comes with a 77Kwh battery! I understand the cost is a lot more but it seems better value for money than a stand alone battery.
Depends on if the car is actually there. Also, you're putting extra cycles onto the cars battery. Additionally, you can't run the house from the car like you can with a proper battery system. You are right however in that a home storage system is MUCH more expensive per kWh than a car is. I spoke to an installer about using a scrapped I3 battery pack, but he said that whilst he could install it, he wasn't confident on regs and insurance due to its need for a 12v system for parts of the electronics. It's also worth noting that most house batteries are a different chemical composition than car batteries which makes them safer to use. Our 13kWh pack is £7500. You could get 20kWh for £10600. which isn't a m,illion miles away from the £8000 for a 24kWh BMW i3 replacement pack.
VW Buzz ID comes with a 77Kwh battery
VW say it isn't currently possible to do bidirectional charging, but it will be available 'in the future' as a software upgrade on their 77kWh batteries, subject to having a compatible home charger. That means the existing hardware must be adequate, so I'm guessing it will be done on DC, with the inverter and control circuits in the wallbox.
I've just placed an order for a 4.5kw system with solar edge and a Powerwall onto a South facing roof. 8 week lead time on the panels but 8 months for the Powerwall
Can anyone recommend a solar pv installer in the County Durham area?
How many of you have panel optimsers installed?
How many of you have panel optimsers installed?
I have Solaredge optimisers on my 2 arrays. Should have an effect on my smaller array of 6 panels because one of these is shaded until about 2 pm but no idea if they are doing what they are supposed to as I've never bothered to check the output of each panel.
Does anyone know a solar panel installer in North Wales?
My parents are thinking of moving to solar for their electricity given the current cost of energy. They don't even know where to start.
Does anyone know a solar panel installer in North Wales?
My solar array and Powerwall was supplied and fitted by Genfit who are based in Saltney just across the border from Chester. I'm very happy with my installation and whilst you could probably find cheaper out there their prices are competitive and they are very competent. Have a look at their YouTube channel which includes some nice video and drone footage of various installations including mine.
I am sourcing quotes for a 5kWr solar array, a 9+kwr battery and inverter and solar diverter as well as an EV charger.
The one quote I have received so far is from a small company less than 18 months old. They have examples of their work and the owner who I spoke to was very knowledgable and answered all of my questions convincingly (of which there were many!!) They have certification and can provide the equipment I specified plus they are a Givenergy installer so give it another week and will get them out for a survey.
Before you say it I know the tennis court needs attention but I had all those solar panels to pay for 😂😂
Not quite but we're having a good solar day today. Powerwall at 100%, washing machine and tumble drier on and EV charging.
You can see the effect of optimisers if you look at the top array of panels. The one on the extreme right is still in shade but the others in the circuit are near to full power so the shaded panel is not throttling the output of the others. I think thats what optimers are supposed to do.
I was supposed to have had a tech from an installation company call me yesterday to go through more of what they could offer, but they didn't call, so I think we are back to square one. _Slightly_ annoyed.
On topic, but slightly different.
We have to change gas combo boiler (old). We have small south facing roof area that could only fit few panels.
So was thinking could add 2x Solar thermals, new boiler and new 2x coil tank?
This is all to help reduce gas for hot water only? (dunno if will even help much financially??) (3 bathrooms, 4 bed, 4 people house).
2nd thought, could I add several PVs, and use it to virtually direct drive electric immersion in tank? Or am I being plain daft????!! Thanks
As many pv panels as you could fit on the roof would be the better way, they're fit and forget unlike solar thermal which can be troublesome.
Pv with something like an immersun diverter to drive the emersion heater.
Solar thermal is also a one trick pony as in will only heat your water, whereas pv will heat your water via emersion heater and provide electricity when the emersion is off.
After a long wait trying to get someone to actually call back, I finally have an order in for solar.
16 panels on the 10mx4m workshop roof and a 5kWh battery in the workshop. Parts, installation and paperwork included in the cost (165k SEK) with a predicted payback time of 11 years, or less depending on how high the price per kWh goes over here.
Site inspection/technical planning in about four weeks, but installation in March.
I get the impression solar thermal is obsolete now. PV panels are cheaper, easier to install and far less maintenance. They can power things other than hot water, and if you don't need the power you get paid for it instead.
They will also heat water better at lower sun intensity; solar thermal is more efficient at high intensity, but at those levels you've probably got spare PV anyway so it doesn't matter.
magic thanks for input, will go and properly measure and see how many PVs I can fit. Are they standard size?
i have solar PV - i have a battery being installed soon.
I'm engaging with some installers to get solar thermal installed.
different horse different tricks.
efficiency depends on if its flat plate or evacuated tubes though.
but id go solar PV all day if i had nothing.
(I also heat my water with oil currently which means my economy calc is very different to gas)
Has anyone got an Afore inverter and successfully connected it to the app to monitor? I've already got the system installed - came on a new build - and interested to see what I can view etc
Having a 'mare trying to connect the inverter to the app
There's a company called Naked Energy which claims to have vacuum tube technology which generates thermal input for hot water and electricity at the same time.
Cor, this tech is another world, isn't it? Is therd a good place for a numpty to read up on it all? We've been quoted £11k for 9 x 410w panels, a 5.12kw battery and and a Solice inverter, is that any good?
It's not a bad price. We're paying £17k for a 5.5kw inset array with a 13kwh battery. I'd check the usable capacity of the battery as the small ones didn't used to be great.

Sounds a little pricey but should save you almost £1000 per year if you can use all the solar generation. These days finding a competent installer that doesn;t have a months long waiting list is a challenge so if the installer giving you a quote has all the equipment in stock and can start in the near future I'd go for it.
Is there any way you could squeeze more panels onto your roof even if they will be East or West facing? Adding more panels won't add much to the cost as the cost of scaffolding, installers, and other electrical materials will be the same whether you add 9 panels or 12.
Nothing wrong with east and west facing panels.
Overall production will be down a small amount compared to South facing panels, but on a spring/summer day you get more production in the morning and evening which is arguably when you want it!
Nothing wrong with east and west facing panels.
True. Half my array is west facing
Thanks both - it's been oddly troublesome actually getting someone to come and quote, but it feels wrong to just go for the first company that van be arsed to turn up and look!

Cheers, will do - "insert array", is that, like, the total potential power of your panels? So ours would be, like, 3.6kw...?
Will ask about the battery - just the two of us, so not sure how big it needs to be? Just switched energy supplier, so rather guessing how much we actuslly use at the mo. 🙁

Grand, thank you. Just looking at the schematic they've sent, if it's to scale it looks like they could turn a couple to add another couple on, but the corners would be just sticking over the edge - is that a no-no in case of high winds? Can they be mounted on south-east facing walls or on a frame to angle south on agarage roof? I'll be asking them these questions too!

Surprising that you are having trouble getting quotes as the initial quote doesn't require a visit and is usually done by them looking at your house on Google Earth but it could be all your local installers are chokka and don't want to take on any more work at the moment.
Hiya Guys,
I'm thinking of Solar as many seem to be one note I do have is have people also considered wind power?
In England wind turbines are allowed as permitted development and where I live, just 200 metres from the Bristol channel, I'd get a fair return on the investment and the new ones are quite efficient and reasonably good at generation of power.

Wind turbines for domestic use are, historically, a waste of space, they don't scale down well at all. Unless something revolutionary has happened in the last 12 months I can't see that being any different.

We've been looking, not particularly diligently, for years, but every company we've tried has either not returned calls or insisted on a visit and no-one's ever turned up. 🙁
The first time anyone from the company we used visited was when they turned up for the install, they didn't even ask for photos. I was a bit doubtful they could actually fit on the number of panels they said, but they managed it...
These days I don't think you've got much choice but to go for the first company that responds, you could be waiting years trying to get more quotes, by which time prices will have risen to higher than whatever that first quote was anyway.
In England wind turbines are allowed as permitted development
while this is true - i suggest that you read the rules around the permitted development.
you will find you require a large plot of land as the bottom of the turbine has to be X from the ground - the center of the turbine has to be X from the ground and the whole thing has to be +5m(iirc) - but its for sure X meters from a from any boundary if it were to fall over.
I'd be staying clear of turbines after this happened locally to me.
It's been fixed now 18 months later but not started generating as yet from what I can tell.
We are thinking pretty seriously about getting Solar. There's a local company that gets decent reviews and doesn't seem to have a massive waiting list. What do those ITK think of their guide price for one of their systems?

Lipo Battery Storage
I thought when I lifted it off their site that it was a bit vague. I'll see if I can find some more info.
If there is a decent amount of battery storage then its a good deal.
I have a question about battery storage.
A lot of people on here seem to be jumping on it as part of a new installation but do you actually know how much it's going to save you?
The reason I'm asking is that I have two houses both with PV that's been installed for about 10 years - love it!
In that time I've gathered a lot of data from both systems and I know that I'm going to get the following average daily generation:
October: 5-6kWh
November: 3-4kWh
December: 2-3kWh
January: 2-3kWh
February: 4-5kWh
This data is from a pure S facing unobstructed 3kWp installation - so add maybe 25% for a 4kWp array. My other house has 4kWp but facing E/W and does worse during these months.
So, given the pretty low production during these months I'm struggling to see how, after the house has taken its base load plus anything else that's running, you can put more than a couple of kWh into the battery for use after dark.
ATM it just doesn't seem to make sense - unless you have a much bigger array - is it worth it?
Please educate me in where I'm going wrong!!
(At my place with the E/W array I have a lot of space and am looking at buying some used panels and building a south facing ground mounted array to boost the winter production.)
my data for baseload shows a 35ish% use of generated power at any given time - despite a concerted effort to use timers etc.
Im looking at the battery like a capacitor to smooth that out rather than believing I'm going to be going off grid as per some of the lunatics out there.
exporting at current SEG is a waste of paper.
I've just been reading this:
The other advantage of battery storage is that you can charge from the grid on a cheaper overnight tariff.
If you can remember the old economy 7 tariff then the newer tariffs are similar albeit with less hours normally.
Octopus energy is currently offering overnight rates between 12:30am and 4.30am for less than 8 pence per kWh!
Batteries can be programmed using the inverter software to charge during this period thus saving more money, this is especially useful in winter when generation is significantly less through the day and early mornings. Waking up to a 50% charged battery could be just the boost you need to see you through your morning routine before the sun comes around and wakes up your Solar Panels.
The other advantage of battery storage is that you can charge from the grid on a cheaper overnight tariff.
Yep, I absolutely get that, and it's an interesting thought..... but how long are they going to keep offering that? There's no guarantee they will given that the power generating rule book has been thrown out of the window!
Good point.
This (from The Times) suggests that they will be keeping lower tariffs at non-peak times for the foreseeable:
The National Grid is currently consulting on an initiative that will pay customers to use energy at off-peak times this winter.
It’s based on a trial with Octopus Energy earlier this year. The scheme offered discounts to 100,000 households who reduced their energy consumption during two-hour windows, such as 9am to 11am and 4.30pm to 6.30pm. The aim was to rebalance demand at the grid.
The trial took place in February and March. Those who cut back received credit or had the option to receive money straight back into their bank accounts.
Octopus said consumers on average saved 23p per each two-hour trial window, but some participants saved up to £4.35.
If rolled out nationwide, households would have the option to save money by using energy-draining devices such as electric car chargers when demand is low.
The National Grid Electricity System Operator is understood to be working on an announcement for the plan which could be in place by October.
Those with smart meters could get up to £6 per kilowatt hour (kWh) saved at a time when bills will be sky-high.
One kWh is enough energy to power a dishwasher for less than an hour, or use an electric shower for six minutes. A tumble dryer uses roughly 4.5 kWh per cycle, according to estimates.
If there is a decent amount of battery storage then its a good deal.
Battery storage is available in a selection of sizes from various manufacturers and below is a few examples:
Pylontech 2.4kWh / 3.5kWh / 4.8kWh
Uhome 2.4kWh
Growatt 3.3kWh / 6.5kWh
Greenlink 3.2kWh
You're right that it may be hard make full use of the battery in the winter, but winter isn't really a worthwhile time for solar in the UK. The real problem for me is in summer, when the battery is going to be full in a few hours and the rest of your output will be exported.
Whether to spend money on more panels, rather than a battery, is an interesting question. If export rates go up in parallel to grid supply rates, exporting becomes more cost effective. On the other hand, if load-dependent grid charges become more widespread, a battery that you can use to shift off the peak (which is valid even in winter) become more viable.

or hedge your bets and go for a bit of both ?

Yes indeed if you have nothing to mop up the excess a lot will be exported so at least make sure your battery is sized to cover your evening and early morning needs, consider a solar diverter for hot water and if you have an EV try to have it plugged in during the day. This June before my Powerwall was installed and due to building work I couldn't have my EV plugged into the charger during the day, I exported 324 kWh, half the power my array generated, and imported probably the same again. If my Powerwall had been installed and the EV had been plugged in I would have exported nothing and would have had between 500-1000 miles of free motoring and wouldn't have spent £97 on that imported power.
Having said that I'm seeing that the battery is having a good effect in the "shoulder" months like now where we're past peak solar. The solar generation is now equal to domestic use and the battery is enabling me to be off grid for the last couple of weeks. I think even a small battery could be worthwhile to make maximum use of solar during the day by acting as a buffer/accumulator. For example if you have the washer and drier on using say 2.5 kW and your array is generating 3kW then without a battery you are essentially losing the excess to the grid. Say a cloud moves across the sun and the array output drops to 1.0 kW then you start drawing 1.5 kW from the grid. Having a small battery would prevent the need for grid power during a sunny period day like that.
how effective is using an induction heater in a hot water tank at burning off excess energy vs using a battery? It seems like its a much cheaper option to start with (if you have a hot water tank)?
Energy required to heat 250 litres of water from 20°C to 60°C is 11.63 kWh so heating water would be a pretty good sink for excess solar. In comparison a Tesla Powerwall holds 12.5kWh.
ta. I presume there's gear so that you can trigger the induction loop only when there's excess electricity being generated (so I'm not burning grid electricity on a cloudy day)? What is that sort of thing called so I can google-fu it
The real problem for me is in summer, when the battery is going to be full in a few hours
..... and households generally need the least amount of power!
how effective is using an induction heater in a hot water tank at burning off excess energy vs using a battery?
You're not 'burning it off' - your're using it productively!
Anyway, pretty damn good - you can think of the water tank as a battery in some respects.
Our holiday place is all electric and our 3kWp array basically will provide all our hot water for 3-4 of us every day from May- Sept (just looked and the 210L tank is currently 59.7c).
If you have a tank then a diverter is the very first thing you should install.
Once the tank is up to max temperature the diverter (Immersun) sends power to a standalone heater that's only connected to the diverter and not to the ring main. This caused an issue during the first lockdown as I couldn't go the the house to switch this heater off and the internal temperature was well over 30c!!
If export rates go up in parallel to grid supply rates, exporting becomes more cost effective.
Ha, some chance! I get 4.5p/kWh deemed as export - that said I'm getting over 60p/kWh I generate regardless of whether it's exported or used internally!
solar immersion diverter
Iboost is a popular one for those that like programable gadgets
Solic is a much cheaper more basic unit .
- i use a solic to feed two Oil filled radiators to use up would be exported energy in winter.

When I self build I am going to properly investigate a seasonal thermal store, under or in the house, with solar charging and heat pump extraction.

isn't that just intended to store energy for a ~24 hours (like a hot water tank), rather than seasonally? I can't see it staying warm for more than a week

Scaled up it would be great tech.
On that scale it seems somewhat pointless over having hot water tank. A few folk on a Facebook group I'm in have them and they are pretty slow at releasing heat back to water. - think poor combi style
Someone on here works for Sunamps competitors and was rather scathing 😂
They did come up during my research for my uni project but as you say it's a rather low grade heat that needs proper optimisation, it's definitely not a fit and forget product. There have been some trials, East Lothian housing association and somewhere in Northern England. The latter had terrible results but that seemed unsurprising as they were just flung into ancient housing stock with no other work done and largely reluctant participants. A bit like folk who mean that heat pumps don't work because they won't heat a radiator to scalding point.
They're actually a good idea but as always it's down to the execution.
that said I’m getting over 60p/kWh I generate regardless of whether it’s exported or used internally!
This is one of the reasons the energy market is stuffed. Feed-in tariffs should be scrapped now and the money saved used to fund energy for people who can’t afford it.
Interesting about sunamp.
There's a good few self build versions, using big (3m3) sand or water seasonal storage....hmmm
Feed-in tariffs should be scrapped now and the money saved used to fund energy for people who can’t afford it.
New FITs have been scrapped now, and were scaled back a lot before then. In the grand scheme of things there aren't that many people getting FIT at that level, the systems are small and those systems will either finish their FIT period or become ineligible through upgrades or decommissioning at some point. They probably paid a lot of money as early adopters so the incentive was required.
Export tariffs now are a pittance, if anything they could do to rise to match the increased cost of electricity in general.
Yep, the level of FITS we get didn't last very long at all and were quickly reduced.
Our system was expensive but had probably paid for itself by now.

I was just looking at the figures and potential because of where I live. I looked into the issues and problems. Looks majorly scary in terms of vibration and then energy production doesn't seem that good.
Bearing in mind that I've lost two wind speed anemometers in two years, the height required not keen on.
Maybe one year someone will fix the main issues with them but I guess it's just Solar for me.
Shame really because here potentially they could generate a fair bit of power 😉
JeZ
Maybe one year someone will fix the main issues with them but I guess it’s just Solar for me.
I thought a bout a turbine about 15 years ago as we have an open aspect and plenty of space to put one. But the costs where massive and, of course, there's lots of moving bits to go wrong so I think there'd more room for stuff going wrong whereas PV is effective;y fit and forget.
I can’t see it staying warm for more than a week
Maybe they should substitute water for baked potatoes or McDonalds Hot Apple Pies - both of which seem to stay at nuclear temperatures for days on end!
😉
@mrsparkle I had a quote from a company that uses pylotech batteries however they appear to be housed in a floor mounted cabinet which put me off. They wouldn't fit easily in the space I had earmarked. No concerns about quality as they appear to have a good reputation but this and the fact that the the company could not provide a solar diverter to heat our water is a bit of a non starter for me.
With the energy cap now confirmed, how many people are recalculating their payback period on £10K installations?
This would be a real shame and maybe part of the master plan by big oil to keep us hooked on Hydrocarbons?
They win either way as they would keep the huge profits and people keep drawing from the grid....
No mention of a new Green Deal (Energy Company Obligation ECO scheme) to subsidise renewables. Is the % of the Energy Co. profits monitored to see how much the actually spend on these?
I’m not. Mine was only partially based on the economics, we started our search before Ukraine and the price rises. We knew it would cost us, but that it was the right thing to be doing. If anything, I’d want MORE solar. Next year we’re planning to add another 8 panels which should lift our array to a theoretical 8.5kW, but some will be easy and some west facing. We’ll use the extra for solar water heating.
...maybe part of the master plan by big oil to keep us hooked on Hydrocarbons?
could be. Or maybe it's some sort of political ploy?
We'll continue with our planned PV/battery installation.
Perhaps the cap and so on will reduce demand for PV components and cause prices to stabilise or fall?
With the energy cap now confirmed, how many people are recalculating their payback period on £10K installations?
This would be a real shame and maybe part of the master plan by big oil to keep us hooked on Hydrocarbons?

Solar makes sense, batteries less so. Even at £0.50ppkWh batteries don't make financial sense for my use.
As a two person household who both work full time, a system without batteries doesn't make sense.
Which is why I said for my use. Mrs flicker is at home all day so we can use a good chunk of our generation (around 35%) Over a ten year period the sums for battery storage don't add up even at 50ppkWh, but that's based purely around our own situation.
around 35%)
That's the part that makes no sense without batteries. Unless you can get an immersun or iboost fitted.
With batteries that rises to 85-90% especially if your wfh all day.
I have solar without batteries. Doesn't really make sense at all. Just the battery tech was NMC at the time and I didn't want NMC in my house largely. ..... Life4po was on the horizon but not there yet
