Musk slams SA energy security target.

Despite the Tesla South Australia battery partnership currently being undertaken, Elon Musk’s Tesla has rubbished the South Australian government’s planned SA energy security target, saying it will “hold back technology innovation whilst incentivising incumbent technology … imposing barriers on innovation by excluding rapidly evolving fast response technologies”.

Tesla’s Mark Twidell wrote a submission to the government where Tesla expressed their dissatisfaction with the target, saying “We do not feel that the draft regulations and supporting consultation paper are representative of the current South Australian position as leaders and innovators in the renewable energy space”.

SA Energy Security Target

Multiple major organisations have harshly lambasted the SA energy security target, which is planned to commence on January 1 and will require retailers to buy 36% of their power from South Australian sources. This number will rise to 50% by 2025 and, according to Nyrstar, who made a submission to the government about the target, “given the generation market structure and in particular the high concentration of generation in South Australia and the high underlying cost of the predominant fuel (gas), it is debatable whether the scheme will be effective at reducing pricing due to these factors”.

As per an article from the ABC, other submissions range from urging caution because it may not lower wholesale prices, to killing off plans for a new interconnector which was slated to feed power into the state. Momentum Energy said implementation of this energy security target is “unlikely to have any downward pressure on prices, and will instead become a pure pass-through to customers”. Origin Energy called the legislation “unclear”, and Alinta Energy posited that such a scheme could add $100 to an average bill.

For their part, the government stood by the legislation, with the Energy Minister Tom Koutsantonis advising in parliament on Tuesday that it will lead to “lower wholesale electricity prices”, and will in turn “incentivise more generation”. No word on how exactly that will happen but we’ll undoubtedly hear more from all sides in the coming months. Opposition energy spokesman Dan van Holst Pellekaan noted that “even” the Greens were critical of the plan, labelled the government’s energy policy as “chaotic” and called for independent economic modelling before “inflicting further pain on long suffering South Australian businesses”.

Tesla South Australia battery partnership

A massive boon for South Australian solar today as Tesla’s Elon Musk and the South Australian government have paired with Neoen to create the world’s largest lithium-ion battery. The Tesla South Australia partnership will be a world first and comes off the back of a bunch of Twitter banter in March 2017 between Musk and various Twitter users (initially spearheaded by Atlassian co-founder Mike Cannon-Brookes), where he mentioned he is in discussions with the Premier about installing large scale solar in South Australia.

Tesla South Australia to create world’s biggest battery

The project will be 100MW (or 129MWh) and according to Musk on Twitter earlier in the year, it’ll be installed ‘within 100 days from contract signature or it is free’ – so we’ll be seeing the battery live and working this year! Jay Weatherill, the Premier of South Australia, was quoted as saying  “Battery storage is the future of our national energy market, and the eyes of the world will be following our leadership in this space”.

According to Nick Harmsen on Twitter, the battery will be built alongside Neoen‘s Hornsdale wind farm (currently 315MW), which is in Jamestown (mid-north South Australia). More details of the partnership coming straight from Heatherill’s office are embedded in the Tweet below:

The deputy CEO of Neoen, Romain Desrousseaux, said the project will highlight how large scale storage is now “commercially viable” and will also be able to provide “dependable, distributable power” – which was one of the main problems last year when South Australia suffered numerous lengthy blackouts, including last September when a freak storm damaged transmission lines. According to Weatherill and the ABC, the government had about 91 international bidders for the battery project, which could be used in the future to avoid load-shedding summer blackouts when electricity demand outstrips supply. Solar power (albeit as ‘energy storage’) being used to provide stability for the power grid is a new concept – and we’re very excited to see how it helps the festival state.

Tesla’s Musk was quoted today at a press conference at the Adelaide Oval as saying “It’s a fundamental efficiency improvement to the power grid, and it’s really quite necessary and quite obvious considering a renewable energy future”.

Tesla / South Australia Battery Partnership Reception

In an opinion piece for The Advertiser, Redflow CEO Simon Hackett has said South Australia’s 129 MWh Tesla project sets up the state as a world leader in battery storage. He also noted that it ‘confirms the integral role that batteries will play in the successful exploitation of renewable energy sources’.

Tesla Solar Roof Australia Release Date and Cost

Exciting news from Tesla and Elon Musk last week as he announced that the Tesla Solar Roof Australia preorder is now available: they’ll be available in ‘almost any country’ and deployment will be this year in the US and 2018 for overseas countries.

Tesla Solar Roof Australia

Tesla Solar Roof Australia Release Date

The tiles were announced last October and we reported on a tweet from Musk last month saying preorders were coming soon – and last week Tesla finally announced they have started production on two of their four initial designs. A smooth glass tile and a textured glass tile are available for preorder right now and will be released in Australia in 2018. The website states that the third and fourth designs, ‘tuscan’ and ‘slate’ will be available ‘early 2018’. This probably refers to the commencement of production, so it might be Q3 or Q4 2018 when these are shipped.

Australians can place a fully refundable $1,310 (AUD) deposit via the Tesla website and, although we’ll have to wait until next year for the tiles to ship, excitement is growing and many local retailers are clamouring for install rights to the panels.

Tesla Solar Roof Warranty

The roof is also extremely durable – take a look at a video post from Elon Musk’s Instagram account where Tesla were doing some hail tests on the solar roof vs conventional roofing tiles. The tiles, whilst being half the weight of their competitors, were measured as being three times stronger:

05.03.19 EDIT: Elon has taken the video off Instagram. 

As such, they have a novel idea towards warranty for the tiles – the lifetime of your home or ‘infinity’ – whichever comes first. They also have 30 year power and weatherization (Weatherization means that there will be no water leaks or other weather intrusions during the warranty period that result from installation) warranties in the US. As warranties are generally region specific we will have to wait to see how this changes for the Australian market.

Tesla Solar Roof in 2019

Tesla plans to ramp up the production of the solar roof with “significantly improved manufacturing capabilities during 2019”. They are facing myriad challenges this year so it’ll be fascinating to see how the company traverses these obstacles. Watch this space! 

Tesla ‘Active’ and ‘Non Active’ Solar Panels

The panels come in two flavours – ‘active’ – which means they work as solar panels, and ‘non’ active – just ‘normal’ roof tiles. As there are a number of factors such as cost, sunlight and energy requirements, you’ll be able to choose how many of each you want, keeping in mind that this is a full roof solution, not just adding solar panels to the top of an existing roof. According to Tesla, for a normal home, around 35% of the tiles will be solar.

Tesla Solar Roof Australia Price

As reported, you can place a $1,310 AUD refundable deposit on the website today. 

With regards to the price: “The typical homeowner can expect to pay $US21.85 (~$A29.50 as per today’s exchange rate) per square foot for Solar Roof, and benefit from a beautiful new roof that also increases the value of their home,” a blog post on Tesla’s Solar Roof Website stated. This is assuming 35% coverage of active (solar) panels.

Based on the pricing Tesla have released, if you have a 120 square metre roof (1291.67 square feet) – you can expect to pay around $38,340 AUD for a ‘normal’ Tesla roof install.

These solar roofs are built to complement and integrate with the Tesla Powerwall 2 and we’ll be very interested to see what some of the cost savings are after they’ve been installed and the numbers crunched. Watch this space as we’ll update as soon as any more information is available! You can also sign up for updates from Tesla by clicking here.

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!

Tesla Powerwall 2 Australia Installation

Tesla Powerwall 2’s are being installed in Australia right now. Read our Tesla Powerwall 2 Installation overview!

 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.
