[@pleiadesds2012]

I live in Thailand and just bought a house. As some of you know, Thailand grid is very bad. Power cuts are often and sometimes long. Electricity in price has gone up a bit and there is no cheap tariff. Same price all the time. I'm really interested in getting solar with powerwall to go 100% of grid. Very good video.

[@viveksoty]

same case in India as well. some states have subsidy programs which gives upto 25% of the cost spent in installing tech like in these videos. I think Australia has similar plans like that.

[@MrGoogle87]

I'm pretty sure it needs a working grid to function (sadly enough), and does not work like a back up. Can someone confirm it?

There's a little box on alibaba that'll sort that out.

I have to comment on the honesty of the installer company with regards to payback time. I have had lots of phone calls from companies telling me it would pay back in 2 years etc which i knew was BS but refreshing to see an honest battery fitting company.

[@stevezodiac491]

Darren Finlay-Smith Yes very refreshing, everybody forgets that all these cheap pv panels were paid for by the general energy consumer paying his green tariff made compulsory by hm government, ie poor people paying for rich boys expensive toys, that is why Cameron said lets get rid of this green shit allegedly, when people's energy bills were going through the roof.

[@mgkleym]

Its going to be heavily dependent on electricity costs. I live in one of the better areas for solar in the us but the pay back period is awful because my electricity is cheap about 9.5 cents a kwh in the winter and 10.5 during the summer.

[@michaelmara1338]

I live in Phoenix, AZ and it always boggles my mind that every home and business is not equipped with solar. After all we are the 'Valley of the Sun'. If their were state & federal subsidies working in conjunction with local utilities to help home & business owners to install solar and battery power storage systems such as the Tesla Powerwall 2 we could all contribute to a more sustainable future. Love the videos, please keep them coming!

[@DanielDiaz-by7fc]

They don't even need subsidies in AZ, they need utility companies to stop actively lobbying officials to pass laws that hamstring solar companies.

[@supertuner63]

I live in Scottsdale, I understand where you are coming from! I work in the solar industry and it is so hard to sell solar here. We offer a free program to buy cheaper power and people still don’t do it.

[@thewmreed]

The problem is even with the tax credit which equals between 2k-9k it is still quite expensive. You are looking at roughly 22k from start to finish. Any gov subsidies would have to offset that cost dramatically for most to take advantage of it and make it worthwhile.

[@tennesseetexan1957]

I live in Texas. My average electric bill is $120 per month for a 3 bedroom 2 bath home. I figure the battery costs $7000 USD and the solar array with components to hook it up completely would run another $13000 easy. It would take 14 years to pay for itself assuming my utility bill is zero. He said the battery would last at the most 10 years with diminishing power as time progressed. I don’t see this as feasible or economical for use in the Southern US. I don’t own an electric car because they cost too much. I think solar and wind are wonderful but they have to come way down in cost before they are economical for the average person even with rebates.

[@tennesseetexan1957]

Real M Trump is trying to create jobs in West Virginia. Why don’t the solar manufacturers move there. There in China because they pay slave wages and and the government steals our technologies. China is not as great as you claim. Why don’t Apple and other big American companies build their products here? Because they don’t tax them to death and don’t tell business what they must pay the worker or which benefits they must pay. I’d love to see us more invested in green tech here but the liberals regulate business until they leave the country. As long as coal & natural gas are cheaper then they will dominate. Stop blaming Trump for every problem we have. Our problems predate him. Until we can stop acting like children with all the political hatred, this country will never survive; climate change or not. Politicians have ruined this country. Both sides!

[@TheExumRidge]

We covered every square inch of roof with panels... 7.2K solar... Very happy we did. Never a question about whether we cover the usage. Byproduct of this is that we are growing our electric footprint by adding electric cars(Bolt), ranges, heat pumps, etc. Removing natural gas appliances one-by-one. This is the right thing to do - regardless of payback time - don't even ask the question. What are you doing to help the CO2 problem?

Next time you're in australia, visit HBPowerwall (youtube channel). He made a powerwall using old laptop battery cells of 40 Kwh.

[@tcpnetworks]

Love your work, Kryten. We've got three PW2s and 20kW here in Australia, and we have a Sunny Island unit that effectively keeps us on-grid even when there's no mains power. The power company here cuts our mains off if there's a chance of a bush fire, so having this configuration pretty-much means we never have to start the diesel generator.

[@buixote]

Greetings from California! Just got our Powerwall the other day... ran into an interesting phenomenon... the Gateway decided on two occasions to stop sending power from the Array to the Grid. When I called Tesla to inquire, they said that if utility power is "too low", the gateway will not allow PV power to go to the Grid. Presumably this is related to the hot weather we're having lately... I *did* write our Public Utilities Comission to make sure that our Utility is not trying to "pull a fast one", by intentionally lowering the voltage to avoid having to pay all us micro-generators! ;-)

[@spitexau]

Great video. I am in Australia with a Powerwall 2 and 15KW on the roof. The battery changes EVERYTHING and it's honestly one of the best investments I have added to my home. The App obsession is real too :). Payback on the whole system for me will be sub 5 years...... but obviously we get a lot of sun here (generating 82+kw/h per clear day)! :) I also have the off grid/backup option which is AMAZING on the days with our crazy storms. Settings it to reserve 90% for backup means if it's below that charge level it will also top up from grid before the rough weather arrives! Having power when your neighbourhood is down is hilarious! :)

[@martinwray7001]

John Franks I wonder if you'll still qualify for the 5% vat if you can fit at least one more panel on the roof when purchasing the battery?

[@tagware]

That would change the config. Which FITs crew say would change the feed in tariff. :o( So, our installed in 2010 would drop from 60p to 8.5p. You can get away with installing Micro inverters normally. So, you might be able to wing it on this? Waiting for the Off-Peak facility to be launched. Then you can make it pay for itself just using Shifting load. Good Video though.

[@jasonosler4757]

look at primehybridenergy.com...... already doing this

[@tagware]

Thanks Jason. I left them a message. They seem to have 3 & 5kW version and it seems you add additional batteries against the PowerWalls default 13.4kW. The inverter can only pull 2.5kW against 3.68kW of the Tesla unit. But, as you say they are further down the road on the Islanding Option. It is down to the cost of theses units. I to wait for Prime to contact me now.

[@FSFLIGHTproductions]

When you update your power wall I highly recommend you get the power wall off the floor to at least 18 inches of 2 feet off the floor to avoid a heavy rain storm flooding the garage and shorting out the power wall. Better safe than sorry. Thank you for the detailed video on the power wall. Cheers!

So if you don't mind me asking, if for e.g. you get 50% of your power from Solar in Summer how much do you get in Winter? I'm interested since I'm in the North of england and don't expect much... yet to make the jump to solar!

[@vosi88]

Tesla should allow you to set your car up as a mobile powerwall. If you defined what your minimum required range was the remainder of the battery could be used in powerwall mode as a buffer for the house. Then if you ever need to max it out you can run it in full charge mode. Of course once you reach a defined level of power battery size there are no more gains to be had. Being a bit of an obsessive id be very keen to get my array that bit bigger so i could go virtually off grid :)

It seems to me these are the bane of utilities. I always assume utilities make the majority of the megabucks from prime time power sales.

[@MrGoogle87]

In The Netherlands there is a ''Salderen'' law, which allows solar energy owners to convert it back to the grid on the day (i.e. 3000kWh per year) and use the energy from the grid again without extra cost again when the sun is down again: So you can effectively have a 0kWh per year bill without a battery. I hope more countries do this! We can even get the 21% tax back from purchasing solar panels and installation.

[@toddkes5890]

It will also mean that the power supply will be leveled, so instead of having to build power lines to handle surge times (i.e. daytime air conditioners, and evening with no solar power), the power lines can be built for the average power draw. This will reduce costs, and reduce the need to have expensive peaker plants (plants that pop on quickly but briefly to handle surge demands). Of course, other items would help too, such as ice storage air conditioners (they make either cool air of freeze water to ice, so the power demand is flatter) and multi-hot water tanks (so you use less power at a time, but the heater runs for a longer time period). The goal is to make power demand flatter and more predictable

[@suprakashmishra6358]

In India, most homes use 150Ah-200Ah (around 2KWh) lead batteries with 0.5-0.8 KW inverters for power backup. The batteries are charged from the grid and are used to run a few lights and fans when the power fails for a few hours, and the power fails quite often here due to the aging grid and insufficient availability at many places too. Such a setup costs around 200 pounds and the battery (around 140 pounds) needs to be replaced every 5 years or so. While some places are seeing a solar application of this and also bigger grid-tie and off-grid solutions, it still isn't that widespread considering the country receives a good deal of sunshine. Lithium and solar will have a great market here considering power failures and the abundant Sun. Cost-wise, is lead still economical? Going by 2 kWh lead costing around 140 pounds, a 13.4 kWh array would cost 938 pounds and that is 4000 pounds cheaper than the Powerwall. Is 13.4 kWh lead battery same to a 13.4kWh lithium in terms of load and backup hours? Am I missing a calculation here? Sure the lithium battery will last much much longer (at least 2x, may be even 4x), is more supportive of quicker recharges and discharges, Absolutely love the videos, have been following FullyCharged for years, it just is getting better and better. Wish you could upload a new one every day.

[@TaiViinikka]

Lots of off-grid or rural grid homes in North America already have lead-acid battery set-ups like you described, Suprakash, but Tesla is the first company to go (at mass scale) with lithium batteries for this application. I've wondered why, since lithium has the advantage of being light, which isn't needed for stationery systems. On the other hand, it's also going to take up less space, last longer, and not require H2 gas venting or battery management (e.g. topping up the water levels in lead acid batteries.) On still the other hand, I'd rather see more people buy electric cars or ride electric buses, and continue using lead acid for power backup, so as to avoid a serious shortage of lithium cells on the market! Hard to be sure which way is best!

Beautiful house in beautiful UK where you will receive a: "Nice job chap" for your work well done.

[@armuk]

well said Bramberry.

Wow this guy is gold. He’s really smart in the field and very sharp. I would love to have him come to New York and do my installation. I have a city home and a country home. I would think I need two batteries in my city home and one battery in my country home. And I would use it just as you do, use it during peak hours and charge off peak That’s the true savings. Awesome video very informative.

omg !!! It's Kryton from Red Dwarf !!!! Ahem... sorry... I meant to say "omg !!! It's Robert Llewellyn, the amazing actor of many series and now a KZbinr !!!" (I've been binging (bingeing?) Red Dwarf from series 1 in anticipation of series 11 and 12 (saving 11 to watch with 12) so I was rather excited to see one of my favorite actors now has a channel on one of my favorite topics.... rock on Kryton !!!)

In Australia, the Powerwall 2 can be configured to isolate the house from the grid in the event of a blackout. Here is an example, in the Southern State of Victoria close to Ballarat. (1) 15 minutes from Ballarat Victoria. Battery: Single Tesla Powerwall 2 AC configuration with 6.5kW Rooftop Solar PV, 26*250W panels, most of them are SunTech's.

[@esunisen3862]

If you don't touch the circuit breaker, the Powerwall is still connected to the grid. There is no simple method to prevent this.

[@CharlesGregory]

Thanks John - I'm in Australia as well and I had heard that homes were able to remain with power on battery only in the event of a grid outage - I was surprised when Robert said otherwise and figured it was a difference in standards between UK and Australia.

[@jur4x]

I guess it has to do with British Health&Safety obsession. In Australia, if an automatic relay cuts you off grid once the grid is down is probably ok. In UK, there might be concerns that automation would fail to do this, and there would be risk of electrocution of grid workers that came to fix it. Or something in those lines.

[@esunisen3862]

Problem is that the Powerwall needs to be aware that the grid is down.

Chris is excellent.

[@DirtySanch3z]

battery review by Kryten himself...that's as good as it gets. thx Robert

[@heytheregeorgeygirl]

Wow, he explains it extremely simply! I actually managed to understand how it works. Brilliant! Thank you.

[@S71DYproductions]

How’d you get my PIN number?! Great work as ever team Fully Charged x

[@thepurplesband]

Very good video. Chris was great also.

[@michaelstann3390]

I'm getting a 4.6 k system later this month. I KNOW I'm going to obsess probably every day with the numbers. And I think I'm going to enjoy it. I don't have a Tesla wall. I just have I solar panels connected to the grid with no battery backup yet. Awesome video

[@mgutkowski]

We put our system in at the end of Sept last year. After watching this I contacted joju but their prices were absurd, and with quite pushy sales. Not at all keen to discuss options on the system I actually wanted, which involved mounting solar panels close to the edge of our roof (which is allowed for in the rules, contrary to what most installers will say). We went with Sunlight Future in Bristol who were great. We have an 8.6kW array and twin powerwalls. We needed grid power only in Dec and Jan in our first year.

[@frankdavis2316]

Captain G I had a survey done by Two Charming Joju Representatives yesterday after a Series of Email’s over the previous couple of weeks since my first Enquiry. An enquiry initiated by this Video, which is excellent, and my need for a Charger for an Electric Car, which is arriving in a couple of weeks. The Car Charger is being installed in Two weeks, for a price I am entirely pleased with, and at no point in my dealings with Joju have I been under any pressure from ‘pushy’ Salesmen. Quite the opposite in fact, as a layman I have had the information explained and put before me to make up my own mind. I haven’t had the Final Estimate for the installation of the Solar Panels and Battery yet but I am aware of what the Price could be. Throughout the whole process I have been told about all the alternative products and the variety of Prices and left to choose which ones I want installed. I am pleased to have Joju do the whole of the work in hand.

[@Furyswe1]

Like this Chris guy, well explained all of it really!

[@Lucians_Sword]

He has the trifecta: Solar array, Powerwall 2, and Electric cars...

[@SCWgreg]

A year old, and I just discovered. This is a very informative vid. Thank you for sharing.

[@sevensixtysteve8662]

Awesome video - topic and presentation. So nice to see something working in a real paid for application and not just in theory or the ravings of some mad entrepreneur (which I love by the way !).

[@jaydub51512]

Great video. Really appreciate the candid views from Dr Jardine!

yes but without the magnifying glass!!

[@oldgit8597]

Just had my power wall 2 installed yesterday and a new 6.6k solar system here in Western Australia, will be interesting to see how we go as we are moving in to winter

[@kennethsmith6424]

I enjoy your information on all things solar and on electric cars. I respectfully recommend that you consider doing a video on the electric motors that propel the premium EVs. ICE car engines have been around so long, and there have been so many video discussions about ICE engine characteristics, that many of us viewers know a lot about the most popular v8, 6, and 4 cylinder engines, Significantly however, details about the efficiency, reliability, durability, and performance of electric car motors has taken a back seat to presentations about the characteristics of EVs in general. I suspect that many of us are so ignorant about what costitutes a good electric motor that we would like to know more about what makes them good or bad. Also, who makes the best EV motor, Tesla, VW, Ford, Chevy, Chrysler, Volvo, etc.?

[@jaridkeen123]

Do you get a check from the electric company for the power you are putting into the grid?

[@timjefferson1886]

I get the money paid directly into my bank a/c.

[@ELLENFISHER2008]

In the UK its called a "feed in tariff" and it gets reduced returns even as they charge more for electricity every year... 😔

[@zero15388]

AT LAST!!! yeah!

[@yeisonrodriguez4696]

How awesome is it to see the excitement of the host. I would react the same way.

[@kevinkendaru2180]

This is the first video of your show that I've watched, and I was looking for a video explaining the installation, car charging, the app, and pay back time. Also pangs of nostalgia cos you're that man from Scrapheap Challenge
