SolarCity Reveals Installed Pricing For Tesla Powerwall

Thanks to Solar City spokesman, Jonathan Bass, we now know the installed price of the Tesla Powerwall.

Bass says that Solar City is already taking order for the Powerwall and notes that it offers two payment options.  The 10 kWh Powerwall unit, which Tesla lists for $3,500 minus installation and without an inverter, starts at $5,000 (lease) installed by Solar City with an inverter and other extras.

“For a 10 kilowatt-hour system, customers can prepay $5,000 for a nine-year lease, which includes installation, a maintenance agreement, the electrical inverter and control systems. Customers can also buy the same system outright for $7,140, Bass said.”

Solar City will begin installations of Powerwall this October.

Solar City says that the 7 kWh “daily” pack doesn’t integrate well with rooftop solar needs right now, more specifically that it doesn’t make financial sense due to US regulations on selling extra electricity back to the utilities.  To that end, Solar City is not currently offering Tesla’s 7 kWh pack.

I don’t do leases.

And I’ll do the install myself.

Tell me how much it costs and give us the listed of suggested charge controllers, inverters, and other hardware that I will need.


Years ago, Panasonic came out with a lithium-ion storage battery, but I’m not sure if it’s for sale in the U.S..


It is apparently for sale nowhere, that’s the problem.

In the mean time I bough real for sale material from the German company Effekta and it does really well.


Aren’t you from Germany? From the Panasonic website, it appears to be for sale in Germany under it’s Sanyo brand.


Sanyo branding and contact info:


What’s the price for the 7kW system? Do I take the 500$ difference on the equipment off?


Oops I meant 7kWh.


SolarCity is the king of TPO solar. They won’t let you DIY even though it is simpler than hooking up an electric water heater (most require 2 circuits).

… and they love financing gimmicks with monthly payments for years and years.


The quote in the story above says: “Customers can also buy the same system outright for $7,140, Bass said.” Apparently, that is the installed price.


Ok, so now we know what “for installers” means.


And now, for the real story. Inside EVs, you really need to quit drinking the Kool-Aid on Tesla’s laughable home battery project.

The Powerwall is currently priced to target overseas markets – Australia and Germany according to Tesla in today’s ER. The Powerwall is only expected to be 10-20% of the demand anyways for stationary storage and most of the demand in the U.S. will come from industrial and utility demand. In Hawaii, the Powerwall will be competitive right away due to their high electricity prices and large solar install base. Tesla will be production constrained for now just based on the existing markets that make sense for them and then when the Gigafactory ramps up, they can both lower the cost to build them and the cost they sell them for which opens up the market. Also, the Bloomberg article makes two mistakes – not all Powerwall installations will require a new inverter as many existing solar installs already have one. Also, they compare a Generac without installation and necessary accessories to Tesla’s solution with installation and accessories. You also don’t have to have that many inverters… only one inverter is necessary. And the Generac running costs are far higher including both fuel and maintenance. Since there are going to be many distributors and resellers, the pricing could be far more… Read more »

Compared against a Generac?

Wow. Talk about Primitive.
It’s like having an 18-wheeler outside your house generating Noise, Pollution, CarbonMonoxide and STINK. And feeding a Generac isn’t cheap as it burns about 20 gallons of gas a day, and then you have to take your 5 gallon gas cans to a gas stations that Does Have Electric, for the pumps, and fill up.

It’s the worst “solution” on the market.


Yep . . . there are now a few markets with electricity rates so high that going off-grid with solar PV and batteries can make sense. And Germany & Australia are two of them.

But I think that just the threat of people thinking about going off-grid may cause the utilities to adjust their rates. It might be better to charge a lower rate than to completely lose customers.

It is really hard to accurately judge how popular this product will be . . . it will depend heavily on rate structures, incentives, net-metering regulations, caps on numbers of net-metering customers, etc. And there is going to be a lot of change in the electricity utility regulations over the next 20 years.


I agree that the residential market for this won’t be big.

But that said, there are a fair amount of people that will want it as a way to eliminate blackouts when the grid goes down. A few thousand bucks is a pretty small add-on for the multi-million dollar homes here in California.

Just because you don’t like a product that others see value in, that doesn’t mean the people who see value in it are “drinking the Kool-Aid on Tesla’s laughable home battery project”. They may just have much more money than you and few thousand bucks is a small price to pay to eliminate power outages.


nobody in their right mind would pay SolarCity’s prices. The ROI on the installed prices is like 20 years or more. Sell us the units at Tesla’s prices and we’ll do the rest ourselves.

CounterStrike Cat

Doesn’t matter what it will cost. The solar church believers will pay any price.

I’m generating 13000 kWh of pollution free electricity, and driving pollution free auto all for $85 month. You bet I’m a solar convert!

But this Powerwall is the biggest disappointment to come from Tesla, and now with those install prices for only 10 is also the biggest joke from Tesla and their partners in crime, Solar City!

John MB

..that 13,000 kWh annually and 1000 miles be more specific


Done it for at least one whole year?

Nice numbers 🙂

Big Solar

5.2kw new Sharp UL listed panels installed with enphase M215s for 7000 bucks here.


Good price. Is that before or after Tx credit and state rebate(if any(


@Dennis: How are you assuming we would calculate an ROI for this? I haven’t heard any usage scenarios or enough details yet to allow trying to imagine how the numbers might work. Time-shifting solar is highly dependent on your power company, billing plan (tarrif), PV generation vs home consumption, TOU hours and rates, etc…


You can’t use the 10 kWh Powerwall unit for time shifting. It’s for power backup during a blackout, and thus the battery isn’t designed to go through more than about 50 charging cycles per year.

The 7 kWh Powerwall unit is the one designed for time shifting electricity. Solar City has decided not to sell the 7 kWh unit at this time.

Click on the link in CP’s post above to read about Solar City’s decision.


I genuinely don’t see the appeal in this one. I can readily understand why people would buy Tesla’s cars, but not why anyone would buy Tesla’s house batteries. After reading the details, I honest to God do not get it.

Bill Howland

“Don’t see the use”.

Sven, living in downstate NY, where electric rates are confiscatory (31 cents plus / kwh) vs. 14 cents TOU 12-8, *BUT******, $1.20 2-6pm/kwh in the summertime, would mean for him to get the 14 cent electricity he’d have to use little at any other time since the shoulder peak then is 42 cents plus taxes & fees.

So, depending on what equipment Sven has to have running during the day, he’d need I’d think 3 or 4 of the 7 kwh units. The other question is, since he is not going to be net metered, he’d want the unit to put out no more juice then he is using, since if he sends juice back to the utility its a volunteer operation so he wouldn’t want to do that. Hopefully, the inverters have some kind of a monitoring/blocking system (2 Donut holes on the service wires) so that no power made by the inverter actually ever leaves the home. But saving 1/2 of sven’s electricity bill makes the ROI quite quick I’d think.

Bill Howland
I still think SVEN could call up a solar company, get a SMA 11kw inverter for a few thousand bucks, and, provided they have a mechanism (2 donut holes on the service wires) to monitor power flow (to adjust the inverter output so that it is just a bit less than the power coming in, (example: 10kw output from inverter and 100 watts being used from the utility), then, substantially all his usage would be during the 12-8 am period, which he’d also defer the dishwasher/clothes dryer/washer, and most other high usage appliances. 28kwh of battery would only be an additional 4 kw of charging during the midnight to 8 am cheap period tops.. To this load would be, say 13.2 kw of car charging, and a 6 kw clothes dryer and a 1 kw dishwasher. If Sven has at least a 150 amp electric service, he’d be “in like flynn”. (100 amp service would be right at the limit). And those are worst case numbers… He might not have 2 – 6.6 kw electric cars each with huge batteries (like 2 rav4ev’s or something). Now if he is in the city, 150 amps would be a must since he’d… Read more »

The life of the system is 10 years, it stores 7 kWh and can cycled daily – that works out as a maximum of 10 * 365 * 7 = 25550 kWh’s that can be shifted. If the unit cost $3000 that works out as a minimum price per shifted kWh as $0.12 if it costs $5000 the minimum price is $0.20 per kWh and at $7000 it works out as $0.27. If the life time goes up the price per kWh will go down, similarly if you can’t use all of the kWh’s then the price will go up. You will of course not get all the power back which should be included.

All you need to do now is work out how much shifting power will save you and you can get an idea of if it’s worth it. IMO battery storage on a diverse well connected grid is a long way off viable but at this price those who rely on diesel to fill the gaps in their renewable energy output (like Hawaii) this looks attractive.


scratch Hawaii, I hadn’t looked at the numbers Hawaii probably never has a point where it has surplus RE as it only generated about 8% of it’s power from RE. If that number was 25% and they had a wind farm they had to turn down on occasion then that would be a different matter.


I think Oahu has excess solar power, since about 12 percent of Oahu residents have rooftop solar systems. Daytime off-peak demand hours are from 9am to 2pm, while peak demand hours are from 5pm to 9pm when the majority of residents return home. The electric company is trying go get EV owners to shift their EV charging electric loads to off-peak demand hours rather than peak demand evening hours. A battery storage system could load shift the excess 9am to 2pm solar power to the peak demand evening hours.


Bill, I’ve come to the conclusion that best option for me in NYC is to just get the $.31/kWh flat rate plan and try to size my solar PV system to match my annual electrical usage, minimizing any annual excess electricity for which I would receive the wholesale kWh rate.

Solar PV and TOU rate metering (with it’s insane peak rates) makes absolutely no sense because Con Edison net metering does NOT allow your peak-time produced solar electricity to offset your 12am-8am off-peak electricity usage!!! So my PV panels can never offset the electricity used by my EVs charging overnight. I don’t know whether I can even offset super-peak electric usage with peak-time generated solar electric. I asked con Ed, but they haven’t responded.

Bill, did you know that statewide in NYS if you install a battery-connected solar PV system you are PROHIBITED from using net metering? I listed links to the prohibition in my late reply to you in another thread, which you can find here:

Typo – it should say: See Q4A1 (Question 4 Answer 1). . .


Monopoly stops little guy making a profit: CAPITALISM!


Actually that is called fascism: The merger of state and corporate power. Increasingly big corporates own most of congress via election bribes not to mention special interest lobbyists on capital hill who write the legislation to suit themselves… Unless you have at least a million dollars do you think the political whores will listen to you?


I live in Australia and as noted above, we have some of the most expensive electricity in the world… I have 4.5kw 18 solar panels on my roof. We buy a kwh at 24c and export to teh grid at 8c so i will be very eager especially after the gigafactory is up and running and of course the model 3 when it comes. Here we don’t get any subsidies at all for tesla cars. With a fully configured P85D we are slugged $25K in luxury car tax. This is charged for cars over AU$60,000. The only respite is $100 off registration (i think you call that you licence plate sticker) Big Whoop. I need to leave this country seriously!

Mark Hovis

My Utility Co-op sells to me @ 12 cents/kWh but purchases my generation @ 5 cents/kWh. In a years time, I buy 6000 kWh and sell almost the same amount. Over 15 years, that leaves a $6,300 delta. Currently credits are available to me for up to 55% making the 7kWh battery available to me for $1365. I can’t regain all of the $6,300, but I can make the battery cost a wash. Some of us actually understand that asymmetric compounds absorb heat and we would rather support any cause that moves us away from a carbon economy.

I know you don’t buy into that. I know you think an EV has to have a 100kWh battery to be viable for long distance travel though no manufacturer has any plans for such a battery. I know you think superchargers are a joke. So what exactly are you hoping to accomplish here? Why waste your time?

The big market will be utility and commercial. California & New York now have utility mandates for the utilities to start installing grid level storage and the commercial Tesla battery would be good for that. Commercial operations are often hit by ‘Demand charges’ (charges for having high amp draws). By installing a battery, they can eliminate their demand charges by drawing from the battery instead of grid when they need bursts of power. Residential market probably won’t be very big. But here in California, homes cost millions of dollars. And spending a few thousand to eliminate blackouts when the local grid goes down is valued by some people. Maybe it is not valued by you but some people will buy Powerwalls for that . . . just like they buy Tesla cars which you don’t like either. I certainly wouldn’t mind adding a battery to my solar PV system for a few thousand bucks so it will continue operating even if the grid goes down. (As of now, if the grid goes down, so does my solar PV system. But it would be cool if when the grid goes down, my system isolates itself and then just runs with solar… Read more »

They must think All Our names Are…”Ben Dover” …………L M A O >>


sorry, but that’s a rip off.


small addition: I can get a quality 5.5kv solar array installed professionally on my roof for 13k after tax credits/rebates. If you want to know how, just call around to the smaller solar install companies; Hint: Solar City is not on that list.


On the TMC forums, people have indicated Solar City does overcharge by a lot and really only if you like the financing offers do they make sense. The smaller local install companies can probably offer much better rates.



opinion from Germany with around 20.000 installed Home Storage Systems (All NOT Tesla):

1.) The complete Picture is not shown by Tesla. You get fooled by 3000¢ price announcement.

2.) There are good / better alternatives on the Market from China: BYD B-Box 12.8 for example.

From that storage you can charge / store with 12kw per block. This is really needed, especially when you want to charge a electric car. Scalable up to 50 kWh. And proofed for 15 years worldwide.

On the other Hand LG Chem is entering the Market here with a prepackached extreme small storage up to 12.8 kWh.

Both systems beside 5-6 other Solutions are designed for 48Volt, which means they work immediately with the professional, worldwide used SMA Sunny Island 6.0 or 8.0.

To me Tesla is doing one very good job in Marketing. Never before ALL people have talked about Home Storage. Thank you for that, but I am going for LG or BYD with SMA.


I wouldn’t trust anything from China.


The key question is what is the price and availability on those solutions? I googled but couldn’t find it, while for Tesla they made their price public so installers can’t just rip you off. That they made the price and ordering public is how they got that publicity.


Tesla does have the hype behind them, that is undoubtedly true.

And, yes, it is nice that Tesla gets people talking about these ideas even though they’ve already been around for decades.

Apple wasn’t the first to create an MP3 player or a smartphone. But they sure did well by implementing the ideas well and popularizing them.

Stephen reviewed Powerwall. They were not convinced by the economics. Does anyone see a better pay-off for their situation? Do you care about the economics? I didn’t buy a hybrid then a plug-in to save money.


Yes. Conventional, fossil power isn’t paying all its externalities (lung and cardio disorders, balance of trade, military expenditures, etc.) so dollars on the barrelhead (pun intended) don’t capture the issue.

And even if you don’t care about any of that, what is your spot offer for electricity in a blackout? I can tough it out without any juice overnight, and into the next morning. But after that, I’d easily go from nickels to a dollar or so for small quantities… like a few kWh, here. This is especially true for businesses, which have both more to lose and fewer options in a blackout.
