*A couple of small points to add: Non-rechargeable Lithium and Lithium-Ion ( **tinyurl.com/y6o6hr4t** ) batteries are also recyclable in a majority of areas. Also, It IS possible to recycle normal "post 1997" alkaline, non-rechargeable batteries.... The processor will 'squeeze out' the electrolytic paste (usually by crushing the battery) and recycling the cathode (manganese dioxide) and the anode (zinc compound) and casing (Steel) as normal scrap-metal. It IS possible to re-energize the paste by mixing with new*
Sir William was playing around with it when we met, do you remember?"
Jack said to Clare. "He was storing charges in boxes.
Reconditioned & New Batteries
It's called the Infinity Effect
Excelent Ideas
What an awesome battery recovery ideas!!! Very Pleased!
The thing is, not only you are using free energy, but not burning conventional sources.
That's so awesome!
The owner of this house is missing a trick, he could be saving on his Gas Bill as well by diverting the power that goes back onto the grid into his hot water tank using a Marlec Solar iBoost and the best thing is it won't effect his FIT payments.
I've got one installed and have used it to heat up all my hot water from solar PV since May, this year my gas bill is going to be tiny. Perhaps Robert should mention it on his program.
Vacuum tube solar heat collectors work even in freezing temperatures, and could provide heating (and absorption cooling) with a higher efficiency than using solar PV for heat. But yeah, if you've got excess electricity which you don't get much money for, using it to heat water might be a good idea.
In the UK the output of small PV systems is not measured so you can use all of the electricity you generate and still get paid the same amount.
My gas bills standing charge is higher than the usage costs, robbing bastards.
I have an array of vacuum tubes on my NW facing roof, which heats my water. My gas bill went to £3/month ;)
I have a PV array on my SE facing roof and if I had the cash, I'd get a battery system, but I want something that will stay powering my house, in the event of a power cut.
Trouble is electricity is very cheap, I pay 11 pence a kWh and 17 pence daily standing charge.
If I installed a Powerwall costing say £4,500 it would take me at least 10 years to pay it back and that's assuming I disconnected the mains electricity so I wouldn't have to pay the annual standing charge of £62, if I kept the mains supply as a backup if would take me 11.5 years which exceeds the ten year warranty of the Powerwall itself.
Conclusion, the Tesla Powerwall will have to come down in price by at least 40% to make it viable.
The Powerwall is a bit too expensive still but I think a couple of years down the road batteries will be common in houses and it will help the grid enormously to get off fossil energy.
yeah it should be installed as standard for all new homes built with solar panels
SeemsLegal New houses should at least have a space prepared for a battery, along with cabling, even if it doesn't actually get installed.
Of course, then the grid operators will demand higher rates, supplemented with tax dollars, to maintain their infrastructure.
Probably one of the most informative and useful video for UK residents interested in solar electric generation and storage I've seen, thanks, think I need to 'add to cart'......
no ballpark figure for the retail price? It would be quite helpful to know so as to get an idea of the kinds of savings we're talking about since much of what's not going to the energy company for the power drawn from the grid would be used to repay the upfront cost of the battery pack + solar pv at least initially
Link in the description..
the actual powerwall costs £4,500 from the guy they interview but that doesn't include the solar cells
The cost of a balaclava a screwdriver and that guys address.
If criminals will steel the lead in the roof of my old school, what's stopping them jacking a power wall?
About 240 volts.
Another great video! I hope entire neighborhoods decide to go with this approach, maybe they can get a discount on installation. Idea: have this homeowner keep track of his usage at 1 year and follow up with him in another video, and/or ask him to speak at one of your (another idea) Fully Charged Energy Symposiums. Organize an EV car ride to visit PV and battery homes, then have a seminar with the data.
Scaling it up should make it cheaper and more efficient. I'd love my power to be solar. Hope to go that way in a few years
Solar/battery represents an investment in one's home to save future utility bills. You have to have decided that you're staying at the place for the long term, as (at least in the USA) any installation tax credits are limited to the original owner. You can't sell a house here in the USA with an on-going solar tax credit and have that tax credit carry over to the next owner. If my roof was facing the sun properly (it isn't), I'd certainly put in solar.
I have a small scale home built system the same (not grid connected). In the last year, I have managed to completely power one bedroom. It was scaled as a test, so it can be done. Total costs was around £800, with the largest cost being the inverters.
I also live in a flat and the panels (200watt) are mount on the walls with home made brackets.
You see even people in apartments can do it, well done brother.
+fullychargedshow I hope to see a follow up video - what it is like in the winter (real data), and whole year summary. Also there should be cheaper alternatives to tesla's product.
I certainly plan to do this, and also look at alternatives like Nissan's X-cell which uses old Nissan Leaf batteries, and also RedFlow flow battery alternative, currently only in Australia but coming here soon.
Repurposing old EV car batteries to cheap power walls is brilliant, you should be able to get at least 50% capacity out of them for many years after they're plucked out of a car so if they're 50% cheaper you're not really loosing anything.
How can you say it will save you money if you do not know the price of storage in GBP?
www.solarquotes.com.au/blog/how-the-cost-of-powerwall-storage-doubled-in-11-months/
Think the government ought to look at eco homes with solar and home batteries for all of the proposed new builds instead of spending stupid money on Hinksley.
They need to do both. Most important thing about new buildings is making them passivehouses, then they don't _need_ much heat to run. Retrofitting all the houses in the UK will cost around £360 Billion - i.e. about 50 times as much as Hinkley. (That's assuming 20 grand per house and 18 million need doing (5 millions being not-shit).
This remaking of your entire infrastructure to be low carbon is quite an expensive excercise, although it will of course a) save the world and b) save everyone money after a while as an insulated building stays insulated for it's entire lifetime, saving and _enormous_ amount of money overall because of the energy did not need to be bought or generated.
Unfortunately both people and governments are bad at taking a long-term view.
Asking a question then talking over the answer was just brutal to watch.
Fantastic episode. Love the real world example walk through of an installed powerwall.
Thanks for this video @FullyChargedShow! This is exactly what I want to do for my property and 'seeing' it already happening was great!
This is truly spectacular. It is the essence of The DREAM for me. Set it up, plug everything in, and it just... WORKS! Solar panels with battery backup and grid connection works just perfectly in an urban environment. I would like to see pricing come down, so that even higher capacity battery packs could be used readily in more remote locations that may be entirely off-grid. It is so nice to see how well this integrates into a system no matter your residential situation.
thats the future for home owners
My favourite videos are when bobby is trying to persuade himself he doesn't need something... Then gets it.
Great show as per usual, your variety of topics, applications, devices, and mobility evaluations are always engaging.
Can't say enough about this channel. Its great. More interviews like this please.
Realy wish things like this were more common or even standard on homes and businesses.
This camera work was so professional for the interviews!
Good episode. To add to the comments of your second guest (fellow whose company installs the systems), to my mind one of the greatest benefits of widespread battery storage technology would be to reduce electrical peak demand, which would mean that the least efficient generators would be run less. (This assumes that UK practice is similar to the US, where the generating units are dispatched by a central group in each region that requires the most cost-efficient units to run as mush as possible and relies on the less cost-efficient ones only when there is higher demand, i.e., peaks.) Maximum efficiency may or may not directly correlate with least air pollution, though.
The Tesla powerwall is becoming quite popular here in Hawaii. I have one on order. We have very high grid electricity rates so a powerwall and panels makes good economic sense.
Thanks again, love love love the way you present and share your thoughts!
I JUST LEFT A COMMENT BECAUSE - "PEOPLE DO". Loving the show, I did not think that a wall battery saved so much electric for the family to only use 3 percent a day from the grid. Its a WOW factor, I am officially sold on Tesla.
Let's have infographics like that for every home meter. Once I became aware of how much energy I was using, I hve been able to cut my consumption in half
Right, it's way easier to improve when we can easily measure!
That's one of the things you get with a smart meter (or various electricity monitoring gadgets): much better data.
Have you ever considered doing a trip/video about I.T.E.R. ?
That would be cool!
i hate that ITER will only be online 14 years later, and that is if plans don't change
We had a solar PV hybrid system fitted over a week ago (not tesla) and we've been off grid ever since. We've got 5kw battery storage and also had a clever little Hot Water Dr meter fitted to our hot water storage tank, it heats the storage tank with the surplus from the solar panels when the batteries are full,instead of using the gas boiler to heat water, so not only are we not drawing any electric from the grid, but we're not using any gas for hot water. Saving a fortune plus reducing our carbon footprint. Looking into getting a rainwater harvesting system fitted also.
Gives me a warm fuzzy good feeling for the future - fantastic film and the installer spoke very clearly and knows his stuff 👍
also this film made me up my Patreon pledge by 3 more dollars a month - whats happening to me !
A great article but how much did it cost for the full install ?
Mr. Bob, I wish you could cover the redflow battery technology too.
It's on the cards, very exciting technology but not available in the UK.... yet.
Great video. Both the Powerwall and the Redflow look interesting. Along those lines, is there any chance of a feature on Aquion batteries in the future?
fullychargedshow it is now
Aquion indeed. First cradle to cradle certified battery designed for clean disassembly and reassembly. Very exciting!
How about a cost vs return comparison?
We just got our Tesla Power Wall turned on today. We had Tesla Solar Panels put on about 3 weeks ago. We had to wait for the Excel to come and hook up their part. That’s our energy company.
JLM Energy's Energizr and Phazr systems perform similar functions as the Powerwall, but they have the added benefit of battery back-up in the event of a grid failure. The batteries are also mounted under the solar panels on the roof. They easily install right next to the micro-inverters on the PV module mounting rails, and there is no large battery pack on the wall.
I love your show Mr. RL :) Fully Charged is awesome!
Is there a future rich/poor divide between those affluent middle class types who can afford these energy saving technologies and those living day to day and week to week who will be lumbered with expensive energy and further disadvantaged as a result?
+Shane Semler - the only way I can see that will keep the poor up to date is if there's a government level scheme to supply renewable power + battery to low income households at little or no upfront cost.
I know the UK had a scheme like that for solar panels a few years back. Think it was a few grand towards it rather than free panels though.
That sounds likely.
So how do we make sure that divide doesn't happen? Subsidise home battery packs? I could see that happening for remote locations, but for everyone? not sure there'd be political support for that.
Prices will drop though. Just like with solar panels and such. There's a huuuge market for this kind of set-up in poor countries if the prices go low enough - so I'd bet some companies are trying to get their prices down to that level.
That is why it is vital to support green energy with tax money, which is mostly provided by wealthier people.
I am pretty right wing, small government persuasion. I don't like tax, I don't like over regulation. But I think renewable energy is an issue for society as a whole. Whatever the most suitable suite of technologies is, it needs to be as centrally managed as the national grid is now.
Some social housing providers are more than happy to put solar panels on their homes.
what is the cost of that installment? and what is a prediction to start earning money for giving electricity back to the grid?
Can you give us an approximate breakdown of what the system cost and what the savings are per year? Also explain why you haven't ordered a Tesla Powerwall. If it saves money, then surely you should order one now?
Very interesting videos as always! I can't wait until we're all generating and using our own cleaner electricity.
Interesting article Robert. It would be nice to see an extended video with the interviews with all of the family and how their usage has changed, if possible.
I see the benefits Robert but nothing about the initial outlay for a set up like this?
lmgtfy.com/?q=tesla+powerwall+price
Really depends where you are and if you get any sort of government subsidy or that kind of stuff.
Oh the irony, the man who played Kryten is now making films about batteries. In all seriousness I love what you are doing, power generation is just one of many battles we are fighting to preserve our planet for future generations and I think it is such a huge help when the great and the good really get behind causes like this. Of course the crucial thing we all must remember is that no officer with false teeth should attempt oral sex in zero gravity. Keep up the good work.
Good reason why LED lighting is growing so fast: I took my house and reduced the lights by 800+ watts! Substitube is perfect for typical fluro tubes too. 20W and as quickly turned on as a bulb! No retrofit!
finally you did it , what a great episode
Got an ad for an electric scooter before the vid... finally something more relevant than massive diesel 4x4 cars 😁
Love the work you're doing on this channel! keep up the great job.
for the last 15 years or so dad has had a 10kw wind turbine out at the farm and i'v always wondered why he didn't get a battery back up at the same time but he always said it was a pain in the butt to wire in and configure with all the BIG deep cycle batteries and needed a ton of space as well, so he didn't bother. now i'm looking into getting solar panels on the house and garage and a couple Tesla walls for the house and the machine shed which would be super helpful because we have animals and the well has an electric pump.
when we loose power in the winter we loose heating and water for a solid day with a couple powerwalls we can keep the house warm due to the wood fired boiler heating that cycles water to the central heating and the well and heating wrap to keep the pipes from freezing will keep the water flowing. not to mention the severe weather in the summer as well.
with a couple powerwalls and another 2kw of solar will keep us fully off grid on nice days and put the whole farm at about 2-3% from the grid
this comment is because people leave comments
leave and let leave 'comments
This is a reply... because people sometimes do that as well.
why are they talking about saving pounds in this video? In the USA most people want to lose pounds.
One easy way to dump excess solar in a battery is to charge your electric car during the day if you are producing more power using solar than you are using for other things. Also set dishwasher time to mid day if not home to soak up excess extra power produced. We also use electric washer and electric dryer during day if possible again if you are producing more solar than consuming. I have been able drop my use off the grid by 25% over the year. Do this only if you are producing more in daytime than consuming. I am fortunate to be able work from the home and we have 2 Volts so we can sometimes switch off cars to charge during the day.
Another top way to reduce power use is by swapping to LED lighting. I took my house down by 800+ watts by replacing the bulbs and tube! Substitube is perfect for typical fluro tubes! 20W when I think the older ones use more, no dangerous powders within and turns on as quickly as a bulb! No retrofit!
In the time since this episode went out, Tesla has doubled the energy capacity of the Powerwall and built in their own inverter. It's more expensive, but that's some crazy year-on-year improvement.
At 4:16 a car charging device is shown. Is this used by the family? If yes, is this included in the only 4% use of grid electricity. If yes, does the installed system use the car as an additional battery if it is hooked up during peak times?
Appliances will become so efficient it may not even be sensible to install a large solar panel system with batteries. My energy usage as a singleton is down to about 1kwh per day or £80 per year (on a green tariff by the way) which would not make it worth spending £1000s on system. For example my home now has 5W LEDS each costing a £1 from a popular pound store that replaced 20W bulbs. I use a bike and public transport too so I see the most important act for people without large families is to switch to a green tariff and choose energy efficient products and let the big boys build the renewable energy plants. It can be worth it if you have a large family >2 kids.
So how does the power wall compare to Ikea's? As the solar and battery combo explodes we need to know the detailed differences and benefits of both.
The electric savings are due to having solar - not so much from the Powerwall. The Powerwall will never pay for itself. It does add value, but serves to stabilize the grid and shift energy usage (a bit) from mid-day to the evening. I'm waiting for the real game changer - the Liquid Metal Battery.
Interesting I have a friend that pushes electricity back on the grid here in South Africa and his meter is running backwards during that time. In the evening he uses the energy he generated during the day. Effectively using the national grid as his battery. He still has a back battery system that is just idling. He wrote his own script to monitor his electricity use.
Congrats! They are a beautiful well built product!!! I should know...I work at the Gigafactory. Enjoy.
It would have been nice to get an idea of installation costs, but interesting video, thanks
Would be nice to learn how long does it have to be used to pay installation costs back.
From £4500 apparently
You're basically looking at around £11000 max in total for the panels and the battery and inverter. Seeing that 3 bedroom houses typically spend £1700 on electricity bills per year, you pay all that back in 6.5 years
James Lane I have a five bed house. Over the last three months I used £85 of electricity. That equates to £340 for the year.
I looked at the Tesla Powerwall 2, their web page recommended 4 powerwall 2 panels. Cost $22,000! Or roughly 44 years to cover its cost.
Sadly these battery packs don't last half that time.
Which brings me to the output, they're a bit vague about that. Reading between the lines Tesla seem to be limiting the output to preserve the battery life. They offer a 10 year guarantee based on their battery output levels.
Is the output enough when you put on the kettle, washing machine oven? No, not even half the necessary output on my calculations.
When Tesla and other companies are able to offer systems with double the output, double the battery life at half the cost they may have a "goer". We're not there just yet sadly.
Interesting, thanks for letting me know
Love the Telsa Powerwall, what a great use of the 18650 cells :)
Isn't it better to install it in the basement, because of relative stable temperature?
UK Homes don't have basements like north american homes...basement is very rare.
We don't have basements in the UK, we just have attics.
It could be stolen too(?)
Powerwall has operating temperature 0-50 degrees Celsius. you could steal it I guess. But it weighs 98kg (215lb) and needs to be properly isolated from live power before tinkering. In addition, all Powerwall installed are live back-to-base at Tesla HQ as well as the installer's data feed.
Nick Pfitzner the beauty of mankind is the ability to steal anything. But yeah, it is hard, no doubt about that
Why not have more that one battery.
Could you link it to wind power or water (water mill) if it's all ready attached to the house or want to add later
i assume with a larger house or consumption you could install them in series/parallel. then again i have no idea
Technically you could connect multiple batteries but as they said in the video, when the battery is completely charged, then it covers 97% of their needs. So it's not a problem of the battery but rather of the energy source. If you add another source (like wind power) to charge it when it's not as sunny, then you could compensate for that.
Even small wind turbines are quite loud
+pcfreak1992 was thinking for winter or other times
+Onoff314 I sow one on a house think on hear
We are currently going through the process to add PV solar to our home in Arizona, in the U.S. We have been told repeatedly that it is is currently not possible to purchase a Tesla Powerwall in the U.S. A couple of reasons are offered. 1) Tesla has sold out their entire 2016 production for storage already. 2) The Model 3 will suck up battery production capacity. 3) Tesla is revamping the Powerwall to include an integrated solution (not requiring a separate inverter). 4) Tesla cut backroom deals with the power companies that were going after net metering in the legislatures of states like Arizona (which would diminish demand for SolarCity products) and the backroom deal included Tesla's agreement to pull Powerwall sales in the U.S. Not sure if any, or all, of these reasons are true, but the end result is you need to be in the UK, Europe or Australia to buy a Powerwall.
loving the videos please keep making more and really informative your doing all of us a great service (:
You should revisit in like april to se how it was during the winter.
Loved it Robert, thank you :)
I am really enjoying your show!
Just curious but couldn't you install just the powerwall battery and use the grid to charge it during the day and run the battery at night during peak times? Day time rates are usually considerably cheaper than night rates. I mean sure, you really want a solar setup and save even more, just curious
How much is this sort of package?
Tesla's Powerpack is at first glance merely a battery pack but for some unexplainable reasons it is more than that, it's kind of a sexy thing
Really enjoyed the first episode of new red dwarf
🙈🙉🙊
No mention that I caught of the overall initial set-up costs of the solar panels and the Tesla Powerwall.
Or more specifically, what is the payback period!? IE: How long before the savings in the monthly electricity bill have covered the total initial set-up costs? Some specific numbers please....
This will make amazing sense to balance the grid in the future, once we are legally allowed to have export contracts for energy, so we can sell stored electricity back into the grid at peak times for better rates than the puny current deemed export tariff (4.5p/kwh). Until then, though, having your own battery seems mostly a high-carbon indulgence (given the large construction footprint and then not being likely to need to full-cycle it most days for your own use) and a disincentive to use energy efficiently.
Also, Robert - great enthusiasm, but a few more plausible figures would be good! U.K. avg electricity bill is more like £500, and with PV (as you know) hopefully plenty lower than that. Our last year with PV has seen us buy just 800 kWh from the grid, so that leaves only maybe £100 left to be saved by storage - it would take a very long time (£4-5000 installed... 40-50 years?!) to make any saving with a Powerwall for us!
Hello Robert, thank you very much for this well edited and informative video!
It would be very nice if you could do a followup after a year has passed to see how the statistics look like.
Also, could you give some more information about the system, how much power can it deliver at peak (when is that 6% of grid power used), how the time of return time looks like and what the total battery capacity is?
Last question, what was that power connector that can be seen on the wall? is that for charging electric car? what are the specs on that (V/A)? from what it looks like to me, an electric car battery is much larger than what you have in a powerwall.. so how effective will that be for charging your car?
Thanks again for a great video!
The Tesla wall is a great concept, but as a cheaper interim I use a solar iboost immersion heater. Over the year the panels have made about 4MWh and about 1MWh of excess power went into hot water, for a cost of £200. I'll look at a battery in a year or so.
I realise that the solar panels can supply the grid, but can the battery too, or is it up to you to use all the battery energy stored during the sunny hours (otherwise it is wasted?).
I think I recall this idea being mentioned in a previous fully charged, though, irrc, that was drawn from the cars that are plugged in, rather than fixed batteries like this.
When adopting this technology, would you also remove the gas boiler in your house? So that everything can run on electricity.
My information directly from Tesla is as follows: The purchase price for resellers is a little over 3000 Euros.However, end price here is over 7000 Euros. At 7000 Euros and with a 20 year planned lifespan, here in Austria it would take almost 20 years for the power wall to pay off itself. So basically, resellers are making the Powerwall pointless.
And they have to because otherwise it'd be way cheaper than the competing products. So they jack up the price.
Citation required.
Fennecbutt No citation needed you joker. I spoke to Tesla Energy on the phone. I have the written offer and all the prices right here.
You can also check out the consumer price here: www.photovoltaik4all.de/tesla-powerwall
EUR 5100 for the powerwall. EUR 960 for the interface box. EUR 1000 for the "installation". The offer I have from a local company in Austria was in the same ballpark. And if you're a company you can call up Tesla and ask for a reseller quote and you'll know I am right.
You're making the (somewhat flawed) assumption that power-from-the grid prices will remain the same over the lifetime of the Powerwall. How realistic do you think that assumption is?
Rich Teer Oh you are absolutely right, the grid prices will probably change and it's very difficult to tell where they are going. This may well make the powerwall profitable even at the higher price point.
But my point is: The prices are being hiked up by the middle-men. That's a fact. And I can tell you that Tesla knows about this, and is not happy at all.
Luckily we will be seeing more competition in this area very soon. Kreisel Energy plans to offer a much more attractive package in four different sizes - we'll see whether they are able to actually deliver. And I'm sure Tesla has learned a lot from this as well, so there'll no doubt be a solution to this issue.
of course the "middle man" ist going to add his cut, of course the installing company is going to charge to safely install the system into the home electrical system and also to configure the system, something most people cant or arent willing to do themselves. What do you expect, a free installation? If you have a company and an electricians license, then you can order it at resale price, and install it yourself.
This is superb! Imagine if people could connect their houses together and share the energy they created with near by neighbours, that way you could avoid the grid altogether, no more electricity bills :)
theres a guy in the Netherlands who began doing that and still is - video is on you tube( somewhere)
why go to that expense you can just use the existing grid and do the same thing. Also local grids are still limited to the amount of sun and wind an area get.
This is correct, there are pilot projects being started. They are using electric cars as the neighbourhood batteries. The bigger the micro-grid/connected community, the better the system becomes.
grammophonecat Until it becomes so big it essentially a national grid.
We in the West in most places don't need to recreate copies of existing infrastructure. There may be small islands where this is useful, but in most places the national grid is good enough that you might as well just stick with it instead of trying to replicate it.
During winter can you charge the battery from the grid during the night when you have a lower energy price during the night?
Yes. It depends on local regulations and how the system is configured. Some power companies don't permit it
I want one too. During the bright months we can generate around 20kw per day but mostly use electricity when the sun has gone to bed.
Interesting that it's mounted outdoors, I would have thought indoor to keep the cells warm?
Robert, when talking about cost reduction, you obviously skipped the fact that over a half of your invoice is fixed. So whether you're taking electricity from the grud or not you'll have to pay fixed fees anyways
In the UK we only pay a small standing charge of £0.15 per day or £50 per year. Normal UK bill for using 3500 kWh is about £500. Installing a solar PV system and battery storage would reduce this by three quarters.
I would have liked to know what were his house and solar panels surface area and the rough idea of the cost of the invesment.
We need this badly in France! Brilliant!
I wonder if there is a difference between this brand and regular grid-tied pv systems? It would have been interesting to mention a comparison. Great show!!
How about charging the battery pack from the grid in the winter during off peak hours to be used during peak hours?
I reserved a Powerwall when it was announced (over a year ago) and I'm still waiting. I'm not sure how they are rolling them out, but I must be last on the list.
Oops, correction from my post below.
I pay 15 USDollars per month to have my 4.7 KW solar system connected to the grid (use
my electric company as my battery) I pay $15 per month weather I have a surplus or need to buy KWs because it was not sunny enough.
The last time I looked my electric company was charging me 7.4 cents per KW to buy KWs plus the $15 min monthly charge and lots of taxes with odd sounding names.
For me, seems if the Tesla battery only cost $3,500 to buy, install and maintain the pay back period would seems to be 19.4 years for me (any battery in daily use would probably be vary degraded in 20 years).
Also
Seems if you do have a Tesla battery wall, you would also need to pay the $15 a month any way for the sunless times. So the pay back period above would be even high??? ........
However, I never was good at any type math being dyslexic, so???????
I would love to have one of these! I wish there was some sort of exercise bike that could be linked in to generate any excess you may need
I'd like to do this: install one of these *without* solar panels to save cost on installation. Charge the battery overnight when I can buy electricity for pennies on the dollar, then run my air conditioners off this during the peak heat of the day. With this power plan, electricity is double the cost during peak, but if I can run the air conditioners off stored power, it might be cheaper overall. I wonder what the cost analysis breakdown of this would be.
I would love a system like this on my house but, I suspect, the cost is still quite high. Perhaps in the next few years it'll be down to a reasonable level. Another benefit to this type of system is that it makes owning an electric car a lot more sensible, due to not having to charge it from the grid. Although, you might need a few more solar cells and a 2nd powerwall unit to manage the additional load. I will definitely look into this in the next couple years. I live in Ohio, which isn't the sunniest climate, but if it works this well i the UK, it'll definitely work for me.
Great Ep - would love to see a one yr review of this

This is an interesting clip but absolutely worth pointing out that in Q2 2016 the government slashed the Feed-in-tariff for Solar PV so you really need to do your maths before installing to make any system (including those linked to a battery) pay for itself. Really shame/travesty the FITs were smashed as it just prolongs the countries dependency on other energy sources.
Why not install Powerwall everywhere instead of that 40 billion nuclear power station.
Wonderful idea.
Edit: but then i think something more potent would be needed for factories and businesses that consume a lot more.
In a word lobbying! "Hey mr government buy this cheap power station that won't meet demand and produce toxic waste that still needs to be dealt with for the next thousand years!"
+Idi B just get more power walls. in one of tesla's conferences they showed bigger versions of the powerwalls that would be used to power businesses or even the entire grid and are just a bigger box with more battery cells in
+Tim Rosenburg True that! now i remember.
Yeah you could give a powerwall to 9 milion houses for that money
Fantastic!! sending the link to mates!!
The tesla system in the video ,what price and size was the system ,as in WA Perth a tesla unit is $8000if you want to fit it too an exciting system
Another thing I dont get is why not combine mini wind turbine when installing solar. it might make the difference to make them 100% eco friendly.
Great progress! Did you talk about how to handle macro generation required in the winter? Do we still need full national generation capacity then? If we could crack that then we'd be made.
Great segment Robert!
Would be interesting to go back and look at the generation and consumption over a 12 month period.
There are a couple of interesting business models floating around in which people who generate through solar during the day and store energy with batteries can sell their excess power back into the grid or to their neighbour at peak times at night (6pm-9pm) to create a passive income ad supercharge their investment. Watch this space!
One of my favorite things about Tesla is that they make their products in the U.S.A.
The only downside is that the grid supply will likely cost nearly as much as the energy supplied from the grid. IMO,the standing charges should be included in the unit costs, so those that use most pay most. That might eventually persuade the power wasters to reduce their use. I pay just as much for standing charges as A N Other, even though my energy usage per annum (gas and leccy) is far less than the average.
Good question could have been, what is the expected return on investment from installing the system? How much did it cost versus paying the monthly electricity bill??
