Amazing

"We buy electricity for the batteries 00:30 - 04:30 and charge our EVs at the same time" This works for now, but once all vehicles are EVs and everybody takes advantage of off peak prices to charge then it won't actually be off peak anymore.

@@mnomadvfxThere will almost always be an excess of energy production during the night. Logically, forward thinking companies such as octopus will continue to sell electricity cheaper or give it away during these times. The amounts for buying and selling will fluctuate but there will always be off peak rates.

What Octopus tariff are you on? I just switched to Go for my EV and am thinking of installing solar panels. Sounds like you make 8.5p for your grid export, 111p / 13.2 kWH?

"and the biggest battery allowed for a home system" Wait, wait..... there is a MAXIMUM ALLOWED limit for domestic battery systems?!?! Short of reducing the risk of battery fires in residential areas I can't see any need for such a limit to exist. Hopefully if that is the reason then later solid state batteries which are safer may make such limitations redundant in the future causing them to be removed.

@@mnomadvfx It is not so much because of fires, we got a Phosphate Battery for low risk. It is more because we don't have 3 Phase Power connected. Even so, we only use about 30% of the battery overnight, so it is plenty big enough. Also we are not in a residential area, we are very rural. 😊

"To upgrade our solar system to include battery storage would cost $18,000 NZD" Is it not possible to build a battery system in steps to decrease the 'in the moment' cost? If modular domestic battery systems are not a thing currently that seems remarkably dumb given most people will not be able to afford getting a halfway decent system all at once.

rebates in the pipeline

If many people have battery storage... We all could support the grid when the sun is not shining... But someone decided to bring EV cars into the grid..(fast charging cars needs many megawatts ) . Totally ruining that very attainable goal... Now we need to increase the base load ...

30 years ago nearly every room required 75w to 100w light bulb ..... With led lights it's 7w to 13 w max ... So that took untold demand off the grid... Hence why the grid definitely has the ability to support cars charging... It's due to the load all incandescent light bulbs required..that is now 90 percent lower due to the awesome led light efficiency

@@aperitifs Every time there has been a big improvement in lighting that made it much less expensive to provide the same amount of light (lumens) people have generally spent the same amount of energy/money on lighting. With the switch to compact fluorescent and then to LED lights many people have put more lights in their rooms than they had with incandescent bulbs. One must also look at all of the objects that now come with a light in it that didn’t before, and some of these things have bright LEDs people tape over because they are too bright. About a decade or two ago there was a trend to include a bright blue LED in electronics and it was almost always on. It’s more difficult to find some computer accessories that don’t come with lighting than those that come with it. Look at how popular the LED light strips are. While each of these LEDs only require a small amount of electricity, the increased number of them in our buildings adds up quickly. I was interested to see you write 75W and 100W incandescent bulbs. In my part of the world the most popular type of bulb was the 60W, giving about 800 lumens, and then the 40W for smaller rooms. The LED equivalents to those bulbs are still the most popular here. It’s always interesting to discover how different parts of the world have their preferences.

could loose some weight as well, BUT do you want a slimy suited salesman??????

Fortunately not all local govs are against it.

High user when the heating and cooking is with gas...

Australians are also much higher than 10kW a day!

Also who in the UK uses that much electricity for a standard household??😅 We barely use 6kWh/day (annual average), despite EV charging. Efficiency measures have to be put in place before anything else.

The price given to consumers for each kWh they returned to the grid for those few hours was very high that day - the high price was driven by what the grid would have paid to get a (probably coal fired) peak generator up and running.

How big is your house to fit a 14kw solar system.

For one session octopus was paying £4/kWh and Giv only £2.25 though

@@Lewis_Standing yes, I think Giv upped theirs on the following one. Healthy competition. We made £20 from across both those sessions. We were opted into the Octopus one not Giv. I just trigger it manually to discharge.

What electric heating do you have?

@@computerbob06 5kW ASHP. Heats the water cylinder at night during our off peak.

Which EV? I want the EV9, but not without a bidirectional charger. EG why drop big money on home storage, when a (roughly) ten times the size battery is on the driveway, complete with a set of wheels, should I want to pop out.

@@matbowden9156 Agreed, but sometimes I want to drive the car at night (no battery at the house then) or take it to work during the day (no charging the battery from my solar to feed the house at night, plus the battery is run down some from driving it to work). It seems to me I still need a smaller battery installed at my home.

@@ssoffshore5111 That's just it though. Do you? Really?? Let's roleplay this. If your goal is zero cost (past ya huge initial outlay) then yeah... Making sure ya fridge carries on running whilst you make an impromptu evening dash to the shops in ya car will of course require a home storage battery of sorts. And again, I agree, if others are going to remain in the house whilst the same car is in use for errands, it might end up costing a few pence here and there as it's reasonable to suggest they will clearly consume energy from the grid, as the battery with wheels is off fulfilling it's core role in life. Conversely however, the data tells us that the bulk of the time ya car is just sat there depreciating. Further, the same data tells us that smaller more frequent charging of a bigger battery is better for it vs a full (or close to) duty cycle of a smaller battery, each time. So why not maximise the utility value of the car itself? AKA if ya goal is more around bang for buck, then well, the data says - don't try and fix absolutely everything in one fell swoop - accept that it's a bit like most things in life. What works for you might not work for fella nextdoor, let alone everyone else, and so you'll end up with a bulk saving via V2X vs a complete saving 😉

Yes I agree that the car - most of the time - will for most people be available on the drive to do the job of a battery. Those times it isn’t shouldn’t cost all that much £. Which means a v2l car is a good alternative to batteries. Just that the v2l car isn’t available at low prices. Except the Nissan leaf (used) which might only suit a limited number of people. But in fact as a second car a low range v2l leaf probably works brilliantly as an alternative to a battery.

@@constructioneerful ...there coming!! 😁👍

If the zappi is shedding the car charger during high house loads that is the secret sauce

Fantastic. This is the sort of practical number-crunching in a human way story the channel should do - 2 years is a long enough period for credible feedback. (Need to add a financing cost - now if you spend £7000 upfront, the interest cost is meaningful. If you are lucky enough to not need to borrow, it is still income foregone from something else)

@@furry_homunculus The solar tops up the car when my batteries are full, the main charge comes on at night for 7.5p per kW through "octopus energy" on thier intelligent tariff. It's not designed to be the main charge for the car it's more for the general running of my home as I average 9.8kw a day and my batteries are 10kw. Also an English home doesn't have much space for any more panels, my 10 panels fill up my south facing roof, if I could have more I would but it's the maximum I can fit. Also I don't need Air-con or even "have" or can "fit" a pool into my back garden as it is the size of a postage stamp.

@@furry_homunculus The difference is mostly likely that you use a lot of power for air-con - which is extremely rare in the UK. As are pools, now you mention it!

As soon as the majority start driving EVs and charging at night. Then the day and night demand will be about the same.

I think it will always be a bit cheaper at night, otherwise EV drivers will just charge in the day. But the gap may lessen as battery and other storage systems are developed and their costs decrease. Or the gap might between high and low rates might widen further as more and more variable renewables are added to the grid. I guess that in the end we will develop something like massive electrolysers to produce and compress or liquify hydrogen, to soak up the low rate power, which will later supply it for seasonal needs, ships or planes @@scottkolaya2110

The UK expects to triple the amount of wind power by 2030, and we already produce almost enough to match night-time demand when it's windy. I think that instead of a cheap overnight rate, we're likely to see a bigger price difference but with a more complex scheme that reflects how much wind there is.

@@robinbennett5994 Key words... When windy... Doesn't matter how many turbines you have, you can't control the wind and when there's nothing you have to burn gas.

Let's face it, it's a GivEnergy advert, wrapped up into a video feature (allegedly)! Classic Fully Charged even with 1m subs!

​​@@Robert-cu9bmYou do realize that the sun melts snow. The panels are dark and warmup. Snow melts against the panel and slides off.

@@JohnRoss1 So why do you have burn diesel fuel running snow plows to clear roads, roads are black and absorb the sun's heat. It's also why I've never seen snow on a roof.

@@Robert-cu9bm Not true actually, The 8-Bit Guy did a test recently with a simulated power outage and was supprised when the solar pannels still made power with snow on them .Infact they made more with snow than when its was very overcast .

In your garage, loft, outside, I’ve seen some installed in the hallway. Loads of options.

Octopus has been paying £2/kWh for most of their saving sessions this year, with some paying £4 per kWh. I think the all-in-one has a 5kW inverter, so you could have made £20 a few times in December. For this chap to make £24, the session could have lasted more than the typical one hour or been at a slightly higher price, or he might have had a higher power inverter that isn't released yet. There are only a few of these per year (at the moment), so their impact is relatively small compared to the daily savings over the year. I'd also like to know how he's saving £4 a day. The difference between off and on-peak power is about 20p/kWh, so a 13kWh AIO would only save about £2.30 a day - maybe he has a big solar system too, and was able to recharge the battery.

@@robinbennett5994 Proof renewables are so much cheaper... Only £4kwh. That's why my bills are so cheap they don't bother billing me.

@@robinbennett5994 I'm sure it was a cherry-picked scenario to increase interest and sales...

@@robinbennett5994 You make some good points there, especially the 500 kWh of excess Solar (@ 15p) I exported over the year. Thank you for responding. Amazing opportunity was perhaps overstated by me. I discovered by trial, that the difference between what you use and what you save - also includes what you export. E.g. I normally run on battery all day after charging overnight, so I can’t save anything that I’m not using… However if I export during the saving session - the export figure is used for calculation purposes. This export nets around £5 per saving session which is good, allbeit I’ve only done this twice. I guess at least I know about this now…

Only works for well off people, make it cheaper and pay well so people with money buy and make money. Then when the uptake is high all those go away so the poorer people don't make anything. Look at Australia solar feed in payed really well in the beginning, so people had their system paid off in no time and making money. Now you have solar to maybe break even in years to come and to help ease the high prices of electricity. Not worth feeding into the grid in Australia now. Literally only a few cents kWh.

Don't expect to be making a ton off it. They are currently in the second winter of testing it and paying over the odds to incentivise people to use it, so the numbers people are quoting on DFS are currently inflated. NG ESO have just announced for the remaining 4 tests this year, rather than giving the guaranteed £3/kWh of the previous tests (and £4/kWh in the couple of live events), there will be competitive bidding, and energy companies and the likes of GivEnergy will be bidding against each other. This is likely to dramatically reduce the price consumers get. It's still a great idea, but just need to be weary of the numbers being quoted.

I don't think it's really a problem. A 100A supply gives you 92kWh every day. Putting 13 of those into a big battery hardly makes a dent, and leaves enough for about 300 miles of driving a day, which would work out to 115,000miles per year. If you've only got a 60A connection, that's still 55kWh, which leaves enough for 170 miles a day (or 60,000 miles per year)

I guess that depends on what your grid connection is, my current house (UK) was was built over 10 years ago and is 100A (single phase). But of course many, especially older, properties are going to be 80A or less, and those are likely not going to be easy to upgrade. Just thinking of an example, Looking at the datasheet for the GivEnergy 8.2 kWh (as it's their popular one), that charges and discharges at a max of 80A, with a 59V max change voltage, so that's ~1.8 hours to charge from flat (assuming I got the calculation correct!). Add a 7kW/32A on the wall car charger, and they can add around 20 miles per hour to a cars range (depends on car efficiency of course). So with a flat house battery every day, and only 4 hours of cheap overnight electric, that's the home battery fully charged, and about say 30-35 miles range being added overnight (I'm assuming some power being needed for the house as well, otherwise it would be 40+). This assumes no solar PV as well (or a typical UK winter even with PV!).

@@TheBoothy666 I don't understand how you got the 30-35 miles. If the battery is charging at 4KW and the car at 7kW they're using a total of 11kW. That would be close to a 60A (13kW) connection but there would still be head-room with a 80A (18kW) or 100A (23kW) connection.

@@robinbennett5994 I was assuming charging the car and the home battery were not being done in parallel, i.e. Charge the house for up to 1.9 hours till full, then the car for 2.1 hours (or more). All I was doing was pointing out it's viable with a house battery and an EV, even if you only have a 4 hour overnight slot for cheap elec pricing. Obviously having a integrated control system to manage the car charger and battery system in tandem would make this work better, i.e. charge the car at max rate, and anything left over push into the house battery, (or the other way round depending on your priorities) but not everyone has these things integrated.

Many countries do not have hydro available at the scale you have in Canada. The UK does have cables under the sea to Norway and can transfer energy either way from what I understand. The most important point discussed here surely though is energy security, and locally generated energy. I.e. Home Solar, Battery storage and EV’s. In the UK we would add Wind power to a bigger discussion. When averaged over a single year, our home Solar panels provide 48% of our home power needs. Our GivEnergy inverter, charges our battery system (& EV) overnight (off peak) and we export to the grid at peak times during the day/early evening. We can go off-grid for 3 days in summer if we needed too, and approx 18 Hrs in Winter. So while we remain “grid-tied” we slightly less dependent on it. In fact we would be considered “Prosumers” as we generate power and form part of a virtual power network. Exciting times we live in.

From the hydro in Tasmania to the most northerly coal fired power plant in Queensland is further than Miami to Toronto either by road or in a straight line. Then we can go from Melbourne to the Great Australian Bight and see power lines all the way. What do you think they are doing ?

The US has three grids - California, East coast & central (New York grid) and Texas has their own (ERCOT), and Mexico is separate. Canada has a number of interconnects. However, these are all separate grids run by separate authorities with interconnects. Eastern Australia is definitely the *geographically* largest grid in the world, with a single operator (AEMO). Would be the largest by more than double if we ever connect Western Australia and the Northern Territory to the east coast.

Australia has 20 million buildings and 1million klm of transmission lines and poles and wires. 20 million customers. 5,000klm long, north to south west to Wudinna SA.

​@stephenbrickwood1602 20m buildings for 25m people........ That's some waste of space!

Only nio has active VTG. Load up on cheap energy at night and sell it during the peak day rates thru your car battery. And of course all their swap stations do energy arbitrage as well. Not stationary and pointless megapacks but multi purpose batteries.

@reginald7214 very clever 👏. Elon Musk will do the same at his Tesla rapid charge stations on the main roads. PV panels for the entire site, and big batteries.

@@stephenbrickwood1602 do the big batteries just have that 1 function? Does your Tesla car battery still degrades over its life? Do you only get to choose 1 size battery? So they don't have solar yet, but maybe someday? Every fixed battery ev has a finite life span. That's why the rental companies are running away screaming and going back to gas cars.

@reginald7214 The big batteries would accumulated cheapest electricity when available and then rapidly send large amounts of DC to the customers EV battery when the customer plugs in. I am not an early adopter of new technology because I installed gas and electricity and run 2 older vehicles. Petrol. For me to make the most of electricity we would need to buy new appliances and install rooftop PV. And I am very busy at the moment. Arbitrage is what most grid connected buildings will do with EVs plugged into the grid at the car park spaces. Everything needs maintenance and has a life cycle. Rental companies have their own problems. I think ICE vehicles and petrol will get cheaper to maintain cashflow for as long as possible. All customers know ICE vehicles.

@@stephenbrickwood1602 oh for sure. Except that big battery only performs that function. Nio's big batteries are its own swap station with 23 batteries each. Buy, sell, store, power cars, no degradation, multiple sizes. Spread across huge areas of the country. All in one unit, not Teslas garbage megapacks. And of course high speed charging wastes way more energy than the swap stations do.

He has an EV too…. So quite likely

The details were rather lacking. We only pay $1.50 for 10kWh. Sure, our night time rate is 6¢ so the battery might save us 1.50 - 0.60 or $0.90/day. $0.9 x 365 = $328/yr. I wonder what the whole setup costs.

yep... theres a reason they are lacking in the details, because I don't think it makes sense... I have solar (diy) and ev... but not to save the world, coz they won't and only slightly to save money... diy pays back much quicker... @@scottkolaya2110

GivEnergy All-in-One can output at 6kW, at £4/hr, gives £24. But his house can't have been using any power during the DFS event, and it doesn't account for charging costs. During the last DFS event we turned of the freezer and dehumidifier, and had a candle-light meal, but I don't suggest this for all. It was mainly for fun for my 2 young boys, who got a chance to use their torches. As soon as V2G starts working these DFS events will be even more worthwhile. At present most car chargers are 7kW, but I'd like to get something in the 13-20kW range, partly to benefit from DFS events, but also because I'm on Octopus Agile so faster charging will enable me to make the most of the very lowest rates.

How big did his battery have to be ? from the daily usage- gr-phs ---------It didn't look more than 5kwh ? but to get 24 pounds at he need to run at 6kw max for 4 hours... i.e 24kwh's @@user-kz6tv2hs8j

The 24 quid would have likely been during one of the live DFS we've had this winter, where NG ESO were paying £4/kWh for energy exported. I can't remember if it was a 1 or 1.5hr event, but that works out about right for a 6kWh discharge over the event. But this is currently a trial (currently the second winter they've run it), so I would expect prices offered to drop. In fact, NG ESO have already said for the remaining 4 test sessions left this winter, they are no longer giving the guaranteed £3/kWh they offered in previous tests and instead the DFS providers like energy companies and GivEnergy will have to bit against each other, so that will reduce how much you can make from it.

That already exists. Energy markets are priced every 30 minutes. Octopus offer a tariff called Agile that follows the wholesale market. The reason the cheap overnight rates exist is because Octopus wanted to prove to the market/NG ESO that it could incentivise people to charge at a time that suited the grid and not the owner. They do this by offering a cheap rate. Now they have moved that on to Intelligent, which control when your car charges and when it does, you get the cheap rate, no matter which time of day. Again, its cheap purely to get people to use it, so Octopus can show it works. It's well known that this was a loss leader for Octopus. They are now (or were) trialing being part of the grid balancing mechanism and turning chargers on and off to suit the peaks and troughs of demand on the grid. This will be earning them money which likely balances out the cheap rate to customers.

@@cingramuk in the UK it does. Over here in Portugal not that I am aware of. We get cheaper night tariff despite huge solar capacity. Solar outperforms both wind and hydro by a lot so the only thing beeing "ON" in the night could be Gas or coal 🤐

@@richardblakey3345 you know what you can do, take your own advice and stop telling other people what to do. You don’t know my situation, so don’t assume you do! Tw4t!

Disagree, it’s totally accurate, based on my experience. I think I’ll repay my £11k system in 3-4 years. His house useage might be 10kWh but he also has an EV and 10kW = 40miles at best, so he is quite likely using 20kWh per day which will yield the savings quoted. I charge my batteries and car at 7.5p any solar I make is exported at 15p per kWh. You don’t have to be a mathematician to work out that for a good part of the year you can earn more that you use. Last year I paid just £170 to run a 4 bed house and 2 EV’s. This year my tariffs are much better (15p export as opposed to 4p) so I expect that to be less.

Car charging

I'm guessing they're comparing the savings to the UK electricity price cap of c.29p/kwh for a 'best case' scenario!?

That’s what the installer says but you need to do your own maths. I was quoted 13years and I think it will be 3. The differences for me over the quote are cheap overnight tariff 7.5p, better export tariff 15p, Octopus saving sessions - earned me £95 in Dec. My quote was based on a flat rate of 18p per kWh which I was paying at the time.

UK price is about 30p/kWh at the moment. It doubled when Russia cut off gas exports, but would be even higher if the government wasn't subsidising it for domestic use. Commercial rates were over 70p/kWh last year!

And that is the problem, while your electricity is so cheap you and others will waste, like Gasoline, too cheap STILL thats why 'everyone' drives around in gas guzzling tanks, called utes.

@rivergladesgardenrailroad8834 That certainly is the problem. We do have a lot of relatively cheap electricity. Where I live, it's so cheap, that we let water go around the hydro plant and fall down the falls because it looks pretty and makes more money in tourism than the electricity it generates. The Niagara plant alone generates 12% of what the entire UK uses in electricity, and it runs 24x7x365 and doesn't vary and we have 300 more hydrodams just in NY. Another 1/3 comes from nuclear plants built 50 years ago. Both of those just run 24x7. The remaining 1/3 is from local NG power. Even with substantial subsidies, my rooftop solar has over a 10-year payback and that's with 100% net metering credits. And yeah, it's pathetic that Americans complain about $3.50/gal gasoline like it's ridiculously high and want it back down to $2/gal when no one was driving during the pandemic so they can afford to drive their over-compensating gigantic vehicles. Unfortunately, the below-average American thinks the president controls that. And will vote for anybody that promises low fuel costs, and I mean anybody, criminal or not.

You can do either with GivEnergy. I really like their app which runs locally and/or from cloud data.

Agree. That's either a huge battery or a very rare rate to encounter. Unless you happen to have a lot of excess solar your usually better off averaged across the year charging your batteries at cheap rates, and using your solar / battery. The savings on plans that support this outweigh the payments from selling it back at high rates. As your typically paying a lot more for your incoming tariff, so it just doesn't balance out. It'll be cheap (import) when its hot and sunny, when you don't need to charge. When its cold and grey you won't see a cheap rate. However if you have lots of excess battery and solar DFS will be fine. But at that point you've over paid for your system to be too big. So although its better to operate your big system this way you'd still have been better off buying a smaller system. Of course there are exceptions if you're using very small amounts etc, but with the current options of tarrifs it usually doesn't add up to sell back to grid than just using it cheap.

Rather misleading wording. The MD's All in One can discharge 6kWh in one hour so he would have been paid £4 per kWh. That's a higher rate than usual and there's only about a dozen of these sessions a year. Also to save £4 per day, everyday, means using the full 13.5kWh everyday and having a difference between peak and off peak rate of almost 30p per kWh assuming no losses.

Indeed, if you've gone the whole hog and have say a 50kWh EV which you are charging at any point during the day you aren't going to be making any money even with a 4kW solar array and a small storage battery.

Are you going to make a large hole in the ceiling and convert your loft? Are you going to stick it in a cubby hole maybe under the stairs and throw out all the other stuff you keep in there? Are you going to relocate your consumer unit and basically rewire your house? How are you going to hide the wires. How about installing your system in the shed? Dig up half the garden and drive. There's more to some things than first meets the eye. How about simply buying a brand new home with all the green systems already in place which is probably the best option as retrofitting anything is rarely straight forward and easy. The average solar array will be 4kW max, which you'll rarely get anywhere near and absolutely impossible the majority of the year in the northern hemisphere. The truth is the the average house in the UK isn't suitable for solar or home storage batteries. Don't forget to buy that south facing bungalow with utility space (which are in short supply), along with your solar battery system. The trick is to charge your car on the cheap night time rate. Same goes for using your cooker, washer and dryer etc. The other thing they don't tell is the 3.68kW limit on what you can export to the grid. You are limited by the export regulations on the inverter connected to the grid. You could get lucky and have an application for a larger export approved, but not in the majority of the UK. Don't expect to be going off grid any time soon unless you have a decent size field with the appropriate planning permission in place. Also the moment you turn on any appliances totalling 3.68kW you'll still be drawing from the grid supply. So, that's basically a slow boil kettle and a small toaster. The only time this is not a problem is if you're a vampire that doesn't live during the day. The moment they dig up every road to every house in the UK to upgrade the grid and remove the export regulations, you can sign me up for a battery storage system. Until that happens I'm staying well away and will simply continue to USE the cheap rate electricity at night wherever possible and limit my energy use during the day as I'm never home. When I am home I'm only pulling between 0.1kW and 0.2kW from the grid the majority of the time. The pay back for a guy like me, who doesn't have kids, lives in a small 2 bedroom 2 storey home makes it not worth the hassle nor the worry to have such a system installed. It's simply not financially viable. The payback is too close to the life of the system you're buying. Occasionally I turn the kettle on, run LED lighting, uses mainly a mobile and occasionally turn on the TV. I have 7 hours cheap rate electricity charging 2 EVs, oven and washer on a timer at night and heats his home and water on cheaper gas. As one of my EVs is a 62kWh Nissan Leaf with 10.5kW bidirectional capabilty, the better solution for me would be to purchase a relatively cheap portable inverter or slightly more expensive fixed bidirectional charger and plug in my home during peak rate hours via a simple extension cable. Then I've also got a mobile power plant whenever away from home. The irony is such an inverter invalidates the battery warranty despite Nissan advertising the advantages of the system and mass adopting such a system in Japan. 2 to 3 years till I'm out of warranty and I will have a drivable 62kWh storage battery parked outside with no chance of a thermal runaway inside of the house. Lol and the European car market steered EV drivers to CCS! How dumb! ...and everyone bought it. This video is basically an editorial for a company selling their wares, as are most of the videos on this channel. That's how they make their money. Do your own research, invite a few companies to quote. Ask the correct questions and read between the lines on what they don't/won't tell and you'll soon come to your senses creating your own personal at home green solution. Leave it to the power companies, it's not your problem. In the long run life will be a lot easier. Unless of course you want to spend your life monitoring and maintaining your own system. Clearing snow and cleaning solar panels. Analysing if every component in your system is functioning correctly and all with the added risk of fire. Yep, the chances of a fire are small. Less than winning the lottery, but I'd bet you're still buying those lottery tickets. Take it from someone who went down this route before. Someone who was even collecting the water from their roof. It's a real pain in the backside and takes a lot more time and money than you think. Guarantee something will go wrong when you least expect it and most rely on it. What are you going to do then? Suffer!

100% this was far too much of a ad with nice cherry picked figures

I agree, but they did briefly quote £4k for a typical battery. Of course the All-in-one system they then talked about is £7k before installation costs.

yep, but set yourself a target to get off the bottom ladder....

@@rivergladesgardenrailroad8834 😂😂😂… Yes, witty reply, much appreciated, however, perhaps check your priors? Cheers

Same here, with my current portfolio made from my investments with my personal financial advisor 1 totally agree with you

YES!!! That's exactly her name (Elizabeth Ann Graney) so many people have recommended highly about her and am just starting with her 😊 from Brisbane Australia🇦🇺

I have heard a lot of wonderful things about Elizabeth Ann on the news but didn't believe it until now. I'm definitely trying her out

Such a genuine personality!!, Sincerely speaking. I will continue to trade and stick to Elizabeth Ann daily signals and guides as long as it works well for me.

Sure! She interacts on what's Apk using the digit below👇

The money is saved from not needing to start up extra fossil fuel generators at peak time. 'Peaker' power plants are quite expensive to run.

Gee, you really contributed with an insightful post, eh?
