Tesla Powerwall in 2018 – Availability in Australia.

What can we expect from the Tesla Powerwall in 2018? Elon Musk’s company have released their Q4 report from last year, and it also has a lot of interesting information about the direction they’re planning on taking things in 2018. It looks like the days of the severely limited supply of the Powerwall may be coming to an end.

Tesla Powerwall in 2018 – Residential Energy Storage

The Tesla Powerwall 2 has been out in Australia for almost a year now – the problem is that they have been hard to come by and Tesla have had a very difficult time meeting demand for their energy storage products (we’re not even going to delve into the Model 3 fiasco…)

“2018 will see major growth in Tesla energy storage deployments, as the production ramp of our storage products is just as steep as with Model 3,” Tesla said. “This year, we aim to deploy at least three times the storage capacity we deployed in 2017.”

They went on to elaborate on the reason Powerwalls were so difficult to source last year:

“We also deployed 87 MW of energy generation systems in Q4,
which is 20% less than Q3 2017. Solar MW 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. 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. “

This begs the question – with so many issues scaling up their energy storage how will this impact the Powerwall 3 release date announcement?

Tesla Powerpack in 2018 – Commercial Energy Storage

After the unparalleled success of the Tesla battery in South Australia, it’s unsurprising to see that they’re going to have a strong focus on commercial solar storage. 

 “Due to the success of this project, we’re seeing an increase in demand for Powerpack, our commercial energy storage product. With more electric utilities and governments around the world recognizing the reliability, environmental, and economic benefits of this product, it’s clear that there is a huge opportunity for us in large scale energy storage” their Q4 statement read. 
It’ll be interesting to see exactly what applications we’ll see the Powerpack being used in, both in Australia and worldwide. 

Tesla Solar Roof 2018 Update

According to the report, initial production at the Gigafactory 2 started in Q4 and Tesla are “deliberately ramping production at a gradual pace”. When “fully scaled”, the Buffalo, NY based Gigafactory 2 will be able to produce enough solar cells to add more than 150,000 new residential solar installations every year.

Australian solar installs new record in November

Australian solar installs reached an all-time high of 120MW in November, eclipsing the 100MW in October and the record of 110MW set in June 2012, which was ‘artificially’ (for want of a better word) inflated as it was the last month before Queensland cut off the $0.44c premium feed-in tariff. These are massive numbers when compared with the previous few years and a fantastic indicator for the future of renewable energy in Australia. 

Australian Solar Installs in 2017

According to RenewEconomy and The Green Energy Markets’ Renewable Energy Index, for most months in 2016 solar installs were below 60MW and January 2016 had a measly install amount of 45MW. The reason for the big drop in numbers was due to the end of the premium feed-in tariffs and also the federal government’s substantial cutback of the amount of STC rebate certificates it provided. This means the cost of solar (and payback period) increased substantially, dropping the number of installs and casting doubt upon the industry as a whole.

Over the past 12-18 months, however, there’s been a perfect storm of the gigantic rise in the cost of wholesale electricity, better quality and price of solar panels and storage due to technology advances, and excitement about renewable energy have helped raise the numbers of solar uptake. Public perception and interest in the technology due to such projects as the massive Tesla battery in South Australia, German company sonnen’s ‘free power’ offering via sonnenFlat, and the Powerwall 2 battery have all led to Australia’s domestic and commercial solar uptake reaching this all-time high.

The Renewable Energy Index for October 2017 showed that Queensland leads the way for Australia, with jobs coming via renewable energy projects (both large-scale and rooftop solar) almost doubling over four months from 3,634 at the end of 30 June 2017, to 7,194 in October.

 Amazing news for solar contractors and solar installers – although things may slow down a little over the Christmas period we can’t wait to see what 2018 brings to solar power in Australia. 

Microgrid in Puerto Rico? Tesla Steps In.

In the wake of Hurricane Maria’s landing on Puerto Rico on September 20, the country has been almost completely without power and a majority of the 3.4million residents aren’t able to use fridges, air conditioning, or pump potable water. Enter the possibility of a Microgrid in Puerto Rico – Elon Musk’s Tesla have offered their support to the country by sending hundreds of their Powerwall energy storage batteries – with many already on the ground and more to come. They’re initially being sent to high priority locations such as hospitals which are currently using expensive and hefty gas-powered generators.

Tesla Powerwalls and Puerto Rico

According to news sources such as Bloomberg and Engadget, Tesla is sending hundreds of the Powerwalls to Puerto Rico in an attempt to help shore up its shattered energy infrastructure. The Powerwalls will be paired with solar panels to generate energy while the country works on restoring its main grids. Some of the Powerwalls have already arrived in Puerto Rico and Tesla employees are on the ground assisting in the installation of required infrastructure. According to some sources, grid power won’t return to the entire island for another six months so they’re going to have to look at some options – which may include the full scale renewables – with small grids far more resilient than transmission lines and central grids. These microgrids could be connected to a central grid but also isolated if required. 

Renewable energy expert Tom Rogers told The Washington Post “You look at islands like Dominica, Anguilla, and other islands affected by the recent hurricanes, I’ve spoken to a couple of the utilities, and they say they would prefer to rebuild using distributed generation with storage, and just trying to reduce the amount of transmission lines. Because that’s where their energy systems fail. It’s having these overhead cables.”

Tesla Microgrid in Puerto Rico

After the initial Powerwalls being sent, there have been others talking about the much larger, industrial-size Tesla Powerpack grid scale storage solution and whether this could be an option for the commonwealth moving forwards. Clean Technica report that the island’s utility company, PREPA (Puerto Rico Electric Power Authority), has a massive $9 billion USD in debt to Wall Street and Puerto Rico itself is in debt to the tune of $123 billion (and $74b of them are in defaulted bonds currently in bankruptcy court). In short, the country is in serious financial strife and its grid is virtually worthless. Ricardo Ramos, the CE of PREPA, told CNN the island’s power infrastructure had been basically “destroyed”. 

There’s a possibility of just handing the grid over to its creditors and ‘start again’ – and this could perhaps be the impetus for Tesla to create microgrids across the country with its Powerpack batteries (they scale from 50kW up to 100MWh) – certainly a herculean task but who other than Elon Musk would take something like this on? 

Musk’s team are currently installing Tesla Powerpacks in South Australia under less critical circumstances but it’ll be an interesting litmus test to see if Tesla could roll something out on such a massive scale. 


Volkswagen Electric Car / Battery – $84b Investment

Volkswagen electric car news – they have announced an $84b investment to create a range of electric vehicles – with plans to have electric versions of all 300 models by 2030. Of this $84b, $50b will be invested in battery production to support these vehicles – not directly linked to solar energy but definitely something that will have myriad benefits for the energy storage industry as a whole. 

The Volkswagen Electric Car / Battery Investment

Volkswagen Electric Car Golf 2017

Earlier this year VW announced that they were investing $10b in EVs but appear to have changed their strategy considerably over the past 6 months – planning to overtake Tesla and become the biggest electric vehicle company in the world. They’ll make EVs for Volkswagen as well as their other brands such as Audi and Porsche. 

Volkswagen CEO Matthias Mueller said  “A company like Volkswagen must lead, not follow” – and that “…this is not some vague declaration of intent. It is a strong self-commitment which, from today, becomes the yardstick by which we measure our performance.”

With the 2017 Volkswagen e-Golf’s range called ‘sub-par’ by some reviewers, (the 35.8kWh lithium-ion battery pack is up 50% on its predecessor, but it’s still heavy and can only reach 125 miles) it’s imperative that VW work on their battery technology if they’re to be a real contender in the EV space. According to Auto News new EVs will arrive in 2020 with 300 miles of range for a price similar to the Golf. 

Solar Power charging Electric Vehicles

With the Tesla Powerwall 2, the Tesla Solar Roof and the Tesla EVs looking to integrate more tightly over the coming 12 months, there are a couple of questions with regards to renewable energy and EVs. Firstly, will we see an influx of electric cars with solar panels? Secondly – how tightly will rooftop PV solar and EV recharging integrate over the coming years? 

To answer the first question, it’s definitely something being worked on – last month Audi announced they’re partnering with a Chinese solar panel manufacturer to add a solar roof on Audi’s electric cars. In fact, this dates as far back as the Mazda 929 in 1991 – the technology just hasn’t been good enough. Solar panel tech has been advancing rapidly over the past few years and we expect to see more solar panels on cars over the coming years – they’re cheaper, more flexible, and able to absorb much more energy than previous panels.

Secondly, that’s definitely something people are also trying to solve – energy storage technology plays a massive part in this as the ideal charging times (i.e. when people aren’t at home and therefore not using electricity) aren’t usually times when the car is in its garage! So using smart technology like the Redback Smart Hybrid System and teaching it about electricity usage patterns and joining that up with other information such as weather forecasts will play a key part in marrying solar power and electric vehicles. One thing’s for sure – this technology is going to move a lot faster over the next few years and it won’t be long before EVs are the norm. 


sonnen offering Aussies ‘free power’ via sonnenFlat

German solar battery creator sonnen are offering Australian households ‘free power’ through their sonnenFlat service in an order to bolster their foothold in the Australian market.

Natural Solar, sonnen, and sonnenFlat

Australian supplier and installer of solar products, Natural Solar, have been signed up to manage the offer for sonnen. They are also responsible for the supply and install of Tesla Powerwall 2’s, so they have plenty of experience in large scale product launches.

Sonnen were launched 7 years ago in Wildpoldsried, Germany, and has been growing at a rapid pace since, including their foray into the Australian energy market in 2016.

According to The Australian, sonnen have already gained a massive 13% of the Australian market share since entering it last year. They also sold over 11,000 battery units, ranging from $10,000 to $20,000 – and sonnen sees Australia as its ‘second most important’ market behind Germany – so they are willing to take a (potentially) loss leading strategy in order to gain greater market share for the medium-long term.

The sonnenFlat energy tariff is for sonnenBatterie owners where you receive a guaranteed, prearranged amount of energy for a monthly fee. “In return, some of the energy stored in the sonnenBatterie will be used to assist in the stabilisation of the electricity grid” – according to the sonnenFlat site.

Natural Solar’s website states that the ‘free power’ will be under a tiered system and have explained it thusly:

“Looking at the Germany model for sonnenFlat … storage determines the amount of free electricity the owner is entitled to.

The website also states that: “If a customer exceeds the amount based on their tier, then the owner starts to get charged only for electricity imported from the grid (not from power generated from your solar system and power utilised from your battery) at a rate significantly lower than standard retail electricity rates.” If you can get approved, this sounds like the sort of offer that will propel residential solar+storage from the ‘maybe’ category into the ‘definitely’ for those waiting for a chance to jump into the market.

Australian Tesla Powerwall 2 Installation Guide

Finally, after a litany of false starts and delays, Australians are beginning to enjoy installations of the Tesla Powerwall 2. Michael V, a user on the Australian based Whirlpool forum, documented the process of his install in a thread yesterday and it looks like the process went fairly smoothly, despite the fact that according to Michael it was the installers’ (Flashpoint Electrical and Solar at Punchbowl) first ‘actual’ install (i.e. they had practised on a prototype before but this was the first customer install). According to Tesla’s Facebook page, on April 28 they said that “Powerwall 2 installations have begun in Australia” but this is the first documented information we have on the process so please have a read and let us know if you have any questions or would like to share your experience with Australian Tesla Powerwall 2 Installation in the comments. We’d love to hear about it.

Tesla Powerwall 2 Installation and Ordering Process

The installations management team will help you with the Powerwall install process, which is, as far as we can tell, as follows  (please note this is after you’ve already pre-ordered a Tesla Powerwall 2 – there’s a ~2 month backlog in Australia right now so if you’re on the fence (wall?) about it then click here to visit Tesla’s site and order.

The Powerwall Install Process is as follows:

  1. A Tesla Certified Installer (from Downer Group, in Michael’s circumstance) visits your property to carry out a ‘site assessment’ – which will check:
    1. The suitability of your preferred location for Powerwall 2
    2. Site specific information for Tesla to provide a cost proposal for installation.
  2. A ‘proposal and sales agreement’ is prepared and sent within 7 days. Full payment is required 2 days prior to install.
  3. A Tesla Certified Installer visits your premises to install your brand new Powerwall 2!
  4. Powerwall 2 is connected via 3G (preferred) or Wifi so you can update the firmware and use the Tesla Powerwall App on your phone/tablet.

BYD B-Box Solar Battery vs Tesla Powerwall 2

Edit: As of February 2018 we have a new page with more information about the BYD B-Box in Australia – please click here to read it. 

China’s BYD (Build Your Dreams), the largest producer of lithium-ion rechargeable batteries in the world, have released a new solar battery, the BYD B-Box, to compete with the likes of the Tesla Powerwall, Redflow and LG’s line of energy storage. The media launch was in late March in Sydney and BYD have signaled their intent to move aggressively into the Australian market. They’re a gigantic company based in Shenzhen with a market cap of $22b (Warren Buffet owns 8.25% of the company) and are bigger than Tesla (their battery factory is currently producing a massive 8.6gigawatts, 8 times larger than Tesla’s Nevada Gigafactory) , so they certainly pose a very realistic threat to the incumbent solar battery producers.

BYD B-Box Models

The B-Box comes in high voltage (HV) and low voltage (LV) – with the B-Box LV Residential the solar battery we expect to be the most interest to Australian consumers. The LV model comes in four flavours, listed below (please note you’ll also need to purchase a compatible inverter to go with the B-Box – but given the size of the company we expect that won’t be much of a problem):

BYD B-Box Specs
BYD B-Box Specs (source: solarquotes.com.au via BYD brochure)

BYD B-Box Price in Australia

BYD’s previous solar battery, the Mini, was a 6kWh system which retailed for around $11,000 AUD. Technological improvements and component price decreases means that the B-Box 10 will cost $8,500 AUD for an a 10kWh system, representing a reduction in price per kWh of over 50%. Liu Xue-liang, sales manager has indicated that BYD will be throwing their considerable heft behind the product and BYD’s electric car business, being quoted as saying: “This is not just a new product, it is a new industry,”.

BYD B-Box vs Tesla Powerwall 2

In contrast to the Bbox prices previously outlined, the Tesla Powerwall 1 was a $10,000 system at 7kWh and the Tesla Powerwall 2 will feature a 14kWh battery at $8,000 AUD – slightly more impressive figures for their second gen offering.

According to Adam Clements from Solar Australia the price declines in solar mean a 5.5kW PV roof solar system, inverter, and 7.5kWh BYD battery costs around $15,00 and pays for itself over eight years.

The BYD can have an AC or a DC inverter, as opposed to the AC only Powerwall 2. The B-Boxes also have very high power output, with the B-Box 10 able to give 10.24kW of power continuously (this would empty the battery in less than an hour). In comparison the Powerwall 2 can only output 5kW so if you were using it off-grid or as a backup for power-hungry devices, keep this in mind.

Please take a look at our post on Solar Batteries in Australia and Tesla Powerwall Competitors and Alternatives for further comparisons.

Tesla Powerwall 2 Australia Release Date, Price, Specs, and Competitors.

Tesla Powerwall 2 Australia Release Date

Tesla Powerwall 2 Australia 2018 update: you can get a Powerwall 2 in Australia from a number of different vendors. It depends on which state you’re in – they’re still in hot demand and there are a few states where they’re a bit difficult to come by. If you’re interested in the different energy storage options available to you, please check our solar battery comparison articles (or simply scroll down this article to learn more) – there’s plenty to read up on!

Also have a look at the case study on Gizmodo of a Melbourne man who says the Powerwall 2 will drop his power bill to $0.

According to the Tesla website, there is a ‘May 2017’ install date for Australia. Please note that this has changed a few times already and Tesla have moved the goalposts in other ways, such as removing the DC version of the Powerwall 2, so don’t bet the house on it. But we think Q2 2017 will see some Powerwalls in Australian houses! Watch this space and we’ll be reporting as soon as the first Powerwall 2’s start appearing in Australian homes.

Tesla Powerwall 2 Australia Price

One 14kWh Powerwall battery is priced at $8,000 AUD. Two will cost you $16,000 AUD, and so on. According to the official Tesla site the ‘supporting hardware’ comes to $750 – and if you buy multiple Powerwalls you will only have to pay this $750 once. Please note this price excludes retailer/distributor connection charges which apply in some parts of Australia (more detailed information about this soon). It also excludes installation, which ranges from $1,150 to $2,900 plus permit fees, as per Tesla’s site.

Tesla Powerwall 2 Specs

The Powerwall 2 is substantially upgraded in almost every way from its predecessor, featuring:

  • 1150mm long, 755mm wide, 155mm diameter. (45″ x 30″ x 6″)
  • 14kWh battery (13.5kWh ‘Usable Capacity’)
  • 7kW peak power, 5kW continuous power.
  • Wall or floor mountable, indoor or outdoor.
  • 10 year manufacturer’s warranty
  • Scalable (up to 10 Powerwall 2’s)
  • Integrated Inverter (converts the DC energy into AC energy you need to use in your house)
  • Liquid Cooling
  • Control and view your energy usage/storage with the Tesla app (iOS and Android)
  • Weighs 125kg (276 pounds)
  • Degradation – it will hold around 70% of the 13.5kWh after 10 years.
  • 90% ’round’ trip efficiency.

Earlier this year Tesla were taking orders for a DC (i.e. without an included inverter) version of the Powerwall 2 but this has since been discontinued. The only available version of the Powerwall 2 is the AC version with inverter already built. If you’ve already got panels and an inverter it might be worth looking at alternatives to the Powerwall 2. LG Chem produces the RES7H and RESU10H (follow this link to SolarQuotes who have other great information) with 6.6 and 9.3 kilowatt-hours of usable storage respectively.

Is The Tesla Powerwall Worth It?

Let’s crunch the numbers. Obviously costs and prices will differ from household to household so plug in your own costs to see if a Tesla Powerwall is right for you. Let’s assume you can store the maximum of 13.5kwh each day, and you’ve changed your power plan to peak/offpeak (read more here). Let’s also assume an installation cost of $10,000 AUD ($8,750 to Tesla and $1,250 to cover installation and connection charges / permit fees).

The current off-peak price is around 10c/kWh and the peak price 30c/kWh (in comparison to the ‘standard’ everyday price of ~25c/kWh).

If you were to use all 13.5kWh in peak times, this would save you $2.70 a day, or $985.50 p.a.  (30c – 10c = 20c) (20 c x 13.5) (2.70 x 365).

By the 10th year, assuming the stated 30% degradation, you would have 9.45kWh which represents a saving of $1.89 a day, or $689.85 p.a.

You can use NREL’s PVWatts calculator to find out exactly how much sun you can expect at your residence. It’s a bit complicated but an amazing tool for those who want to get granular about the postential for solar savings.

Tesla Powerwall 2 Australia is only useful for some people at this point in time – solar panel and energy storage technology is coming along in leaps and bounds so this will only get more economical. There are also other options that may suit your individual circumstances.

Tesla Powerwall Competitors and Alternatives

There are a number of Tesla Powerwall alternatives – some would argue that you’re paying for the ‘prestige’ of the name. Always do your research before you buy something based on advertising or what your friends say – solar and solar storage come down to your individual requirements. It’s definitely worthwhile to carefully measure the numbers before you commit to anything!

And without further ado, have a look at some of your other choices – they may not be as sleek, but utilitarian can be sexy too:

 Tesla Powerwall 3 Release Date

No word yet about the Powerwall 3, but as soon as there are any whispers, we’ll have them here. Compared to Powerwall 1, the Powerwall 2 has 40% more peak power, 50% more continuous power, double the storage capacity, an included inverter, and all for the same price. For some people it’s a viable cost-saving option – so if the Powerwall 3 can come even close to some of these improvements from the previous models, we’ll be well on our way for it to be a no brainer to have a solar PV system + energy storage on every roof in the country.

 Tesla Powerwall 2 New Zealand Installation and Price

According to FutureFive, the first New Zealand installation of a Tesla Powerwall 2 occured on August 24, 2017, in a Queenstown home. It was installed by Vector subsidiary PowerSmart Solar and they expect to install many more over the coming months. PowerSmart will also be installing New Zealand’s second Powerwall 2, but after that there are a number of other suppliers who are Tesla Certified and will be offering the product to Kiwis.

The RRP for a Tesla Powerwall 2 (including a Tesla Gateway) is $18,000 NZD for a single 14kWh (13.5 usable kWh) device.

Tesla Solar Roof Shingles in Australia

15.05.2017 UPDATE: More news on the Tesla Solar Roof as Elon Musk tweeted the Tesla Solar Roof Australia release date. (click to read more).

Tesla Solar Roof Panel Release Date

CEO of Tesla, Elon Musk, who recently told Australian PM Malcolm Turnbull he thinks renewable energy and storage are ‘arguably (the) biggest disruption since DC to AC‘ unveiled plans for the new Tesla Solar Roof (correction: they’re thinking about a solar home) back in October last year. As yet, there hadn’t been a release date for the Tesla solar panels but Musk tweeted @HolsMichael last week that they will ‘Start taking orders in April’.

The panels, being touted as ‘the new solar shingles‘, will look just like ordinary tiles but are actually made of textured glass – allowing light to pass through them onto a solar cell situated beneath. According to Bloomberg the cells will be manufactured by Panasonic and the rest done by Tesla. They are in a unique position following a decisive vote (85%) by shareholders to a $2b deal to acquire SolarCity back in November. The purchase of SolarCity, America’s biggest rooftop installer, opens up some amazing opportunities for the company who certainly can’t be castigated for their ‘big picture’ approach and the great vision of Musk. Will Tesla work as a vertically integrated energy firm? Their balance sheet is now laden with debt and they have a lot on their plate including the imminent launch of the Tesla Model 3 – 2017 shapes up as a milestone year for the company.

Tesla Solar Panel Roof Singles in Australia Release Date

As yet, no word on when these will be available in Australia but we’ll be keeping a keen eye out and be sure to update the site as soon as there’s progress on that front! Given that it took Tesla’s acquisition of SolarCity (which has no presence outside of the US) to get these going in America we’re not holding our breaths just yet but Musk and Tesla have a habit of moving fast.

With the battery price of lithium ion falling quite quickly and projected to almost halve in the next 8 years, we expect strong progress to ensue.
