Tesla Powerwall 3 in 2019: Release Date, Specifications, Cost.

Tesla Powerwall 3 Release Date, Specs, Cost, and Rumors.

With the great success of the Tesla Powerwall 2, people are already talking about its successor. Although the Powerwall 2 is a fantastic device and can help many households save a lot of money on their power bill, it’s far from a ‘no brainer’ at this point – you need to crunch the numbers to ensure it’s going to be worthwhile to install in your house. But with the cost of lithium-ion dropping rapidly and Tesla competitors chomping at the bit with innovative solutions to battery storage, we’ve no doubt that there’s plenty of work being done on the Tesla Powerwall 3. Could this be the device that finally makes PV solar + storage a standard for homes? Tesla CEO Elon Musk has said that they “expect to sell more Powerwalls than cars” so it’s a major part of their business. What features will the Powerwall 3 have? What will it cost and when can we expect it? Read on for more…

Tesla Powerwall 3 Release Date

At this point we aren’t sure exactly when the Powerwall 3 is coming out, but let’s look at the time difference between the Powerwall and the Powerwall 2 and see if that gives us any clues:

Powerwall 1: Development commenced in 2012. Announced in 2015 with a pilot demonstration 0f 500 units built and installed. Production moved from Tesla Fremont to Gigafactory 1. Initially came in two models – 10kWh nickel-cobalt-aluminium cathode for backup and 7kWh for daily cycle application. Work on the 10kWh battery was discontinued and they focused on the 7kWh model and brought it to Australia in 2015, with a ten year limited warranty. 

Powerwall 2: Development commencement unknown. Announced in October 2016 at Universal Studios. Production of 2170 cylindrical lithium-ion batteries for the Powerwall 2, Powerpack 2 and Model 3 EVs starts in January, 2017.  First Australian installations early June, 2017. 

Powerwall 3: Potential 2019 announcement.

Tesla Powerwalls in 2019

Tesla’s 129MWh South Australian Battery Farm
According to GTM, in Q4 2017 they deployed 143 MWh of energy storage products, which represented a 45 percent from the same quarter YOY (year-on-year). The 129 MWh of energy storage  the Tesla Battery in South Australia partnership last year will be represented in their figures for Q1 2018.

“Solar [megawatts] deployed declined as volumes continue to be impacted by our decision to close certain sales channels earlier this year and to focus on projects with better margins,” Tesla stated. “In addition, solar deployments were affected by the short supply of Powerwalls for customers who wanted solar plus Powerwall in their house. While volumes may continue to be impacted by these factors over the near term, we expect growth to resume later this year.”

So they were about to build the South Australian battery farm within the 100 days they promised, Tesla had Samsung supply the batteries instead of manufacturing them at their Gigafactory. So it looks like they have a way to go with regards to scaling up their manufacturing processes before we start to even think about seeing a Powerwall 3. 

In America, they’ve released new pricing (thanks to CleanTechnica for the stats): 

Effective October 12th, 2018, the new pricing for three energy products is as follows (in USD):

  • Powerwall: $6,700 (originally $5,900)
  • Gateway: $1,100 (originally $700)
  • Installation: $1,000–3,000 (depending on complexity)

“The Tesla Powerwall is a genuinely good option for consumers considering energy storage, and that quality is part of the reason why so many consumers are asking solar installers for it,” Nick Liberati, communication manager for EnergySage, a solar energy system price comparison site operating in over 30 states, tells Inverse. “However, it’s Tesla’s overall brand recognition and luxury appeal that really sets the Powerwall apart from other battery competitors.”

Tesla Powerwall 3 Specs

This is all conjecture at this point, but we think some of the features the Tesla Powerwall 3 could include:

Tesla Powerwall 3 Specifications and Cost
Tesla Powerwall 3 Specifications and Cost

  • Heavily optimised for and integrated with Tesla Solar Roof (Aussies can preorder one now, will be available in 2018)
  • Heavily optimised and integrated with Tesla Electric Car (Model S, Model 3 etc.). 
  • Upgraded intelligent energy management – will learn your household’s usage, draw from weather forecasts etc. to ensure your house, battery, car or hot water stay at 100% and you are only feeding back into the grid when it’s optimal.
  • Inbuilt hybrid inverter (i.e. you can plug solar panels directly into it, eliminating the need for a separate inverter for your solar panels. The current inverter is just a battery inverter)
  • 28kWh battery (~26kWh usable capacity)
  • We predict they’ll stick with lithium-ion for the battery as its price is very affordable.
  • Alternatively, Tesla may stick with the 14kWh batteries, make them smaller and easier to install – 14kWh is sufficient power for many households – it depends on the cost/size of the batteries)
  • Single and three phase power compatible. 
  • DC version includes inbuilt inverter.
  • By 2018 Tesla expect their Gigafactory to manufacture 35 gigawatt-hours per year of battery cells. Almost as much as the current global combined battery production capacity. What will this mean for the Powerwall III?
  • What features do you think the Powerwall 3 will have? What would make it a ‘no-brainer’ for you to purchase?  Let us know in the comments.

Tesla Powerwall 3 Price

The cost of the Powerwall 1 and the Powerwall 2 was roughly the same, so we don’t expect the price of the Powerwall 3 to fluctuate more than around 20%. 

Powerwall 1 Price (Australian Installation): Around $10,000 (7kWh battery, installation and supporting hardware included).

Powerwall 2 Price (Australian Installation): Around $10,000 (14kWh battery, installation and supporting hardware included).

Powerwall 3 Price: (Australian Installation): We estimate it will stay around $10,000 installed. 

Powerwall Installers in Australia

There are quite a few companies ready to install the Powerwall 2 in Australia – here are some:

Powerwall Alternatives

If you’re not necessarily sold on the Powerwall 2 and don’t want to wait for the Powerwall 3, there are many Powerwall competitors and alternatives you can investigate, such as sonnenBYD B-Box Solar BatteryRedback Technologies, Fronius, Mercedes-Benz, and Eaton Nissan xStorage

Want more alternatives to the Powerwall? Our Solar Battery Comparison area will help – if you have any questions or would like some guidance please email us or simply ask in the questions below! While the Powerwall is certainly an amazing product, depending on your personal circumstances you can get a better result by using one of its competitors. The sonnenBatterie, for example, is onto its 8th iteration and powers 75% of German energy storage – it has a modular capacity from 2-16kWh and, amongst others, is definitely worth a look. 

2019 Update: sonnen have been bought out by Shell so we expect big things from them in the future. If you’re not in a rush and are interested in future technology like the Powerwall 3, keep an eye on our site and we’ll have updates on what’s going on in the constantly changing world of battery storage. 

Dan Petit on CanadianCor.com has an interesting idea about how he’d like the next gen units to work:

An entire integrated package rated at 20 kW after 10 years including Gateway, a basic “next-to-garage-breaker-panel” installation cost included, and standard panels (of 5 or 6 kW) as an entire highly competitive total cost should be a very doable thing. A free pack renewal at ten or so years for pre-orders would be the superclincher!!

Agreed that it would be nice, and doable, but a ‘highly competitive total cost’ doesn’t really scream Tesla, unfortunately. There are better options if budget is your biggest motivator when installing energy storage.

Tesla in 2019 – What to expect – solar implications.

Tesla in 2019 – As the company rockets towards uncharted waters it’s very difficult to predict what Tesla will do in 2019. 

Tesla in 2019 – What to expect – solar implications?

Electrek are reporting that Tesla announced they are unveiling the Model Y solar car on March 14 – an ‘all-electric crossover based on the Model 3’. It’ll be announced in Los Angeles at Tesla Design Studio in Hawthrone, California. 

A shareholder’s letter released last month for Q4 2018 notes that ‘volume production’ of the Model Y should commence by the end of next year (and it’ll probably be done at Tesla’s Gigafactory 1 in Nevada).

“Additionally, this year we will start tooling for Model Y to achieve volume production by the end of 2020, most likely at Gigafactory 1.”

Tesla confirmed their plans for Model Y production at Gigafactory 3 in China at a ground-breaking ceremony back in February.

Although the Tesla electric cars aren’t necessarily to do with solar power per se, Tesla’s impending success or lack thereof relies fairly heavily on these devices. CEO Elon Musk needs the electric cars to succeed to ensure the company has enough money to work on its myriad other projects. They have a lot of competition from other manufacturers such as Mercedes-Benz and Audi who will likely announce their electric automobiles this month.

Some concerns are the Model Y totally cannibalising the Model 3 sales – with the $35,000 Model 3 and the Model X now only available online to lower costs for the financially embattled company. Their shares fell almost 10% last Friday amidst the slew of announcements. 

With regards to solar, Tesla’s main projects are the Powerwall 2, the Tesla solar roof, the commercial scale solar battery storage Tesla Powerpack 2, and potentially the announcement of a Tesla Powerwall 3 release date. To be frank it’s a bit concerning to see all the blood in the water around Tesla right now – let’s cross our fingers for some great results in 2019 for the company.

Tesla’s SolarCity to be heavily downsized.

Tesla’s domestic solar company SolarCity is to be heavily downsized “in line” with a 9% staff cut across the board for the cash-burning company. Approximately a dozen installation facilities and a retail partnership with Home Depot will be closing as it appears Tesla will focus more on producing its Model 3 electric cars, with solar taking somewhat of a back seat for the immediate future.

SolarCity, a residential solar business Tesla bought for $2.6 in 2016, will face some significant cuts including the closing down of ~25% of its installation facilities. The Guardian reported that Tesla haven’t announced which locations will close but an “internal email” advised that the sites which may be closed are located in California, Maryland, New Jersey, Texas, New York, New Hampshire, Connecticut, Arizona and Delaware.

They also fired “dozens” of staffers at solar call centers in Nevada and Utah – so what does this mean for Tesla’s solar future? Has the enigmatic Elon Musk (who owned around 20% of Tesla and SolarCity when the takeover occurred) bitten off more than he can chew with regards to the world’s energy future? You certainly can’t fault his vision – but can he keep all the balls in the air while burning $8,000 a minute?

Tesla’s February Q1 report noted that sales of solar panels “have declined over the last few quarters due in large part to our strategic decision to shutter certain sales channels and market segments.”

According to the report, Tesla deployed 76 megawatts of solar systems during the quarter, or 62 percent less than what SolarCity was deploying in early 2016. It looks like these numbers are set to sink even lower.

The news of Tesla’s solar closures comes hot on the heels of the company initiating legal action against a former Gigafactory worker turned saboteur/whistleblower (depends on which side you’d like to take) – so it’s been a very trying week to add to a fairly trying 12 months for the cash strapped company. 

Would Tesla’s solar enterprise be better off being run separately? We’ll find out soon enough, but fingers crossed in the meantime.
