Tesla in Australia 2018/2019 – Facts & Figures

Tesla have announced their Q2 earnings which notes that they have a ‘crazy’ growth outlook despite cell shortage and a slow deployment of their solar roof. Tesla in Australia is still very far behind the USA, but what can we expect the future to bring?

Tesla in Australia – 2018/19

What can Australians expect from Tesla over the next financial year? We’ve had an agonisingly slow rollout down under and there are many people waiting to see how long it takes for the solar roof to make its way out here.

With the cell shortage that has crippled availability of the Tesla Powerwall 2 in Australia, is it worth waiting for the Powerwall 3 instead? There hasn’t been any announcement yet so it really depends on your personal situation. 

The Tesla Gigafactory in Buffalo, New York is in working on speeding up production of the Solar Roof. They hope to produce 1 GW of solar products at the site annually beginning in 2019, and Tesla has said that it could even reach 2 GW/year down the track. The Gigafactory produces standard solar panels, along with the Solar Roof.

So if you have a bit of patience and are happy to wait until 2019, it’s fine to wait. Solar batteries still have a bit of a ways to go before they are a no-brainer for people to install, let alone the solar roof. But in the meantime, there are certainly solar roof alternatives like the Tractile solar roof tile or the Sonnen/Bristile partnership which they’ve called ‘Solartile‘. Have you got any questions or any experience with any of these solar shingles? Please let us know in the comments. 

Where is the Tesla Solar Roof?

We’ve written about the Tesla Solar Roof before – and we’ve also written about its place in the Australian ecosystem, given that they’re rare as hen’s teeth in America, let alone over here. According to PV Magazine USA, it’s probable that the Tesla Solar Roof will not help their bottom line (Energy Generation and Division Revenues) until halfway through 2019 at the earliest. The reasons for this are for safety and the time lag it’s taking to get all their ducks in a row.

Tesla CEO Elon Musk clarified:

“It takes a while to confirm that the Solar Roof is going to last for 30 years and all the details work out, and we’re working with first responders to make sure it’s safe in the event of a fire and that kind of thing. So it’s quite a long validation program for a roof which has got to last for 30, 40, 50 years, but we also expect to ramp that up next year at our Gigafactory 2 in Buffalo. That’s going to be super exciting.”

According to Musk ‘several hundred’ Solar Roofs have been deployed, are being installed or scheduled for install, and international expansion (i.e. Australia!) is slowly rolling out.

PV Magazine have also written about some of the first solar roof installations in the USA – please click here to read some more about them.

Western Australia Solar Subsidies may be cut – Wyatt

Western Australia Solar Subsidies look like they’re in the firing line right now – with Energy Minister Ben Wyatt advising that he supports either completely scrapping or winding back rooftop solar panel subsidies.

Western Australia Solar Subsidies

Earlier this year the Australian Competition and Consumer Commission called to axe rooftop solar subsidies Australia-wide by 2021. Ben Wyatt said he has asked the Public Utilities Office to have an in depth look about the buyback scheme which could probably do with a bit of an overhaul, or at least a step in the right direction, technology wise.

“While the cost of solar PV systems has reduced significantly since the introduction of the Renewable Energy Target and is now considered economically viable in the absence of government subsidy, the implications of such a change need to be fully thought through, including the impact on the local solar industry,” Mr Wyatt said.

In WA, Synergy currently pays a feed-in tariff of 7.1c/kW to 240,000 households with solar – and over 70,000 customers entitled to the premium solar feed-in tariff which is 40c/kW (there’s no indication that the gov’t is looking at winding back the premium FIT). This is known as the Renewable Energy Buyback Scheme (REBS). Mr Wyatt said that Synergy are paying ‘over the odds’ for this power during hte middle of the day, when demand is low and output high. If you’d like to learn more about WA’s unique energy situation please have a look at this article.

We’re all for furthering the cause of solar, but is it worth taking a look at maybe moving some of the subsidies and tariffs towards energy storage rather than energy generation?

Ray Challen, who was the top energy adviser as the head of the Public Utilities Office up until the end of last year, said he thinks it’s time to consider the best way to continue improving our renewable generation:

“The reason for subsidising any form of behaviour is to produce some sort of greater social good, and it would be difficult to say at the moment that there is a greater social good from subsidising small-scale solar because people could do it anyway,” Mr Challen said. “Not only that but if you wanted to subsidise anything in the power sector then you would be probably subsidising batteries.”

So will we have a solar battery subsidy? It’s hard to say at this point, but many people are talking about making a change to the way we currently reward solar generators. Would a carefully managed solar battery rebate help? Watch this space…

Is There A Solar Battery Rebate In Australia?

We’ve heard whispers of a solar battery rebate doing the rounds. Is Australia about to see its own energy storage subsidy, and, if so, how would the potential rollout of that be implemented?

Solar Battery Rebate in 2018

Solar Battery Rebate in Australia - Tesla Powerwall
Solar Battery Rebate in Australia – Will it include the Tesla Powerwall 2?

We’ve written about solar battery growth before – the sector has seen a sharp rise in 2017 which has continued into 2018. Will the government consider incentivising households and businesses to install energy storage, helping add stability to the grid, lower skyrocketing electricity costs and assist Australia in reaching our Renewable Energy Target? Time will tell. States like Queensland already have the Affordable Energy Program where 5,000 Queenslanders will see an interest-free loan for solar systems/battery storage, so a scheme just for storage doesn’t seem out of the question.

Whilst nothing official has been announced yet, there are plenty of whispers about the government playing with solar power rebates – feed-in-tariffs are dropping sharply. Will we see discounted deals on solar batteries? As they’re not currently at the point where ROI (Return On Investment) is ubiquitously positive, energy storage uptake in Australia is still finding its feet. If the government gives it a boost how much will that cost and what kind of value do we put on the financial/social impact of embracing renewable energy?

In the United States, The federal solar tax credit, also known as the investment tax credit (ITC), allows you to deduct 30% of the cost of installing a solar energy system from your taxes. The ITC applies to residential and commercial systems, and there is no cap on how much you can spend. Should Australia try something like this, or is our current system more effective?

Solar Rebates/Subsidies In 2018 

Here are some of the various offers federal/state government are using to try and get people to embrace solar. Any questions about a specific scheme? Please leave a comment below and we’d be happy to look into your query.

In terms of batteries, we don’t have a specific incentive to install it, either as an add-on to existing solar system or as part of a new system.The Battery Energy Storage System incentive provides eligible South East Queensland households with a one-off $50 payment for registering eligible systems on the Queensland Government battery storage database.

Please note that information about rebates and subsidies can go out of date quite quickly so ensure you double check before purchasing – you can learn more about current available solar rebates in Australia by visiting the “Your Energy Savings” website, which has been set up by the federal government – simply click here to visit

In the meantime, we’re still waiting to see what sort of battery rebate may be offered. Since Australia already has a very strong solar panel presence, it makes sense to work on maximising storage as well as generation.

Redflow batteries in Fiji – to power Digital TV rollout.

Redflow batteries in Fiji – Redflow Limited have shipped $1.2m of Redflow ZBM2 batteries to assist Fiji in rolling out digital TV for its population, according to a press release by the Brisbane/Thailand based company.

Redflow batteries in Fiji

Auckland-based telecommunications infrastructure company Hitech Solutions will install the Redflow batteries in Fiji and have ordered US $1.2m of Redflow’s ZBM2 zinc-bromine flow batteries to store and supply renewable energy which will then power the island’s digital TV.

Redflow Batteries in Fiji - Hitech CEO Derek Gaeth

Hitech will install 5-60 ZBM2 batteries at more than 10 sites in Fiji. Many of these locations are on hills and don’t have access to the country’s electricity grid, so they require energy storage instead.

Redflow CEO Simon Hackett said in a press release that this repeat large sale (Hitech bought the batteries in two separate orders) shows how ZBM2 batteries can displace conventional lead-acid batteries for network power applications in demanding and/or remote environments. “

We are delighted that Hitech has again chosen Redflow batteries,” he said. “This second major sale confirms the unique advantages of our zinc-bromine flow batteries for this high-workload deployment in the tropics. The ZBM2 excels in hot environments and for applications that require high cycle depth and cycle frequency, such as the deployment Hitech is undertaking. This sort of environment and use case wears out lead-acid batteries in relatively short order, requiring their frequent replacement, whereas ZBM2s thrive on heat and hard work.

“We look forward to working with Hitech to ensure its imminent deployments of remote energy systems are successful in a variety of site sizes.”

Redflow’s 10 kilowatt-hour (kWh) ZBM2 is, according to the manufacturer, the world’s smallest zinc-bromine flow battery. The ZBM2 runs at a native 48 volts DC, which means it’s simple to install and deployable in scalable parallel clusters which means high availability, high scale deployments at the largest sites.

The ZBM2 battery comes with a 10-year or 36,500 kWh warranty – a much longer operating life than lead-acid batteries, which are typically replaced every 18-36 months when used in warm climates.

Solar Battery Storage could rise 10x – AEMO

The latest Electricity Statement of Opportunities by the Australian Energy Market Operator (AEMO) forecasts a potential 10x increase in solar battery storage uptake. The statement of operations is produced annually by AEMO and helps them plan for projected installation of solar panels, batteries, and their capacity as the technology increases and Australia continues its march towards our Renewable Energy Target for 2030.

Solar Battery Storage and the AEMO

AEMO’s 2017 Electricity Statement of Opportunities helps us project the next 10 years of energy generation and runs simulations for different scenarios (changes in solar battery technology or peak demand, for example). It’s worth reading the whole thing but here are some interesting tidbits we picked up around the place:

An interesting note that Renew Economy picked up on is that peak demand (with an average of around 3,700MW for the last ten years) was at its second lowest level since 2009 in 2017 – largely in thanks to the high numbers of rooftop solar systems installed throughout the country. Being able to manage peak demand means that infrastructure won’t be as expensive and we simply don’t need as much energy – so it’s a great result!

Cameron Parrotte, the boss of AEMO in Western Australia, discussed the situation and what it means for Aussies:

“While there have been recent retirements of some fossil-fueled generators, new renewable generation capacity is enabling the RCT to be met within the defined reliability standard, and with significantly lower excess capacity than historically recorded”

There’s also some great news for Western Australian solar power, where the grid includes a ‘capacity market’ – making it a bit different than the other states. The report projects that the current amount of live and committed generation resources will meet forecast peak demand in the state’s South West interconnected system (SWIS), despite around 400MW of coal, gas and diesel being replaced by approximately the same amount of rooftop solar, large-scale wind and large-scale solar. If you want to read more about the Wholesale Electricity Market in Western Australia please click here.

Some great news for Australia’s energy future. There’s no doubt that we’ll see more and higher capacity solar batteries installed in houses over the next ten years, let’s see how accurate those projections are!

Senec.Home Intelligent Energy System in Australia

German company Senec has been shipping its products to Australia since early last year, and today we will take a look at the Senec solar battery range – according to the site one of these systems can increase your power self-sufficiency to 80% or more. Let’s take a look and see how they stack up against some of the other solar battery competitors. 

The Senec.Home Smart Energy Management System

Senec Solar Battery
SENEC.Home (source: SENEC)

Energy storage technology has been coming along in leaps and bounds lately – we’ve seen the standard lithium-ion swapped out with hydrogen, perovskite, zinc bromine and other materials. These batteries are lithium ion based as it still remains the most mature technology but it’s important to keep an eye out to see what’s around the corner. Who knows where the tech will take us! 

The Senec.Home is an ‘all in one’ system which includes a Senec inverter, a battery management system and battery modules. You need to manage the solar panels yourself, so make sure you have that planned out before you go and buy everything! Ask your retailer if there’s a good synergy between the system you’ve chosen because it’s an expensive exercise to try and swap or add more solar panels to an existing installation.

Here are some of the benefits of this system:

  • Engineered for 12,000 recharging cycles. This is double the capacity of its unnamed ‘nearest competitor’ (not the Tesla Powerwall 2 as it’s rated for ‘unlimited’ cycles)
  • The SENEC.Home Li system is an automated management system for the panels + battery. It manages your power needs without you doing a thing.
  • Australian service and support, but designed, manufactured and assembled entirely in Germany (except for the Panasonic battery modules).
  • Panasonic manufactured battery with 2.5kWh, 5.0kWh, 7.5kWh, and 10.0kWh options (“depending on the loading and unloading conditions”).
  • 98% maximum battery efficiency. 
  • Soon they’ll have a backup function so the Senec.Home can work when the grid goes down.
  • Up to four units can be daisy-chained to create your own microgrid.

After hosting a product launch last year for the system, it looks like demand for the product has been quite high. The price varies depending on a few factors so please get in touch with your retailer to discuss specifics.

Redflow Thai-stack batteries ZBM2 – filling backorders.

Redflow, who moved their battery manufacturing to Thailand last year, have announced that the first Redflow Thai-stack batteries are now fully complete and ready for customers to purchase. The ZBM2 zinc-bromine flow battery is Redflow’s flagship energy storage product – it looks like it’s almost ready to debut their Thai manufactured version. 

Redflow Thai-stack batteries now ready for customers

According to a press release on the Redflow website, the Thai-made battery stacks were installed on pre-existing ZBM2 battery tank sets and thoroughly tested – passing all pre-delivery tests with flying colours. As such, these completed batteries are now ready to supply existing customer orders. 
 
We reported back in January that they had completed their first battery stacks so it’s great to see them now fully complete and ready to start filling orders of (presumably very patient) customers. Redflow announced in December last year that they had successfully started manufacturing core components for the zinc-bromine flow batteries at its new production facility – so it’s been a fast and relatively seamless transition over to Thailand. Hopefully the lower operating costs can help make these batteries compete with other ‘big name’ options such as the Powerwall 2 or the BYD B-Box
 
Redflow CEO Richard Aird was quoted in the press release as discussing how the  ZBM2 batteries with Thai-made battery stacks have passed the most “critical” hurdle, are now ready to start filling backorders and it should be easier from here:  “Our first requirement of the new factory is quality components, which it is now producing in the electrode stack – the most complex and critical part of our product,” he said.

“Our pre-delivery tests have confirmed that these complete batteries, using Thai-made stacks and existing battery tank sets, perform to standard, so we are now scheduling deliveries to start supplying outstanding back orders.”

sonnenProtect 1300/2500 blackout protection

A big week for German battery manufacturing company sonnen who have announced the sonnenBatterie Protect 1300 – also known as the sonnenProtect. This smart device links with an existing sonnen solar battery and detects mains power outages – at which point it quickly and safely switches you across to use your battery storage for selected appliances. They also have the sonnenProtect 2500, which comes with 2.5kW of power output as opposed to the 1.3kW the 1300 offers. 

A common misconception about solar+storage is that you’ll have power during a blackout. Without something like the sonnen Protect this isn’t the case. 

sonnenProtect aka Sonnen Protect 2500
sonnenProtect aka Sonnen Protect 1300/2500 (source: sonnen)

sonnenProtect 1300, 2500 – Sonnen Protect

The sonnen Protect is installed close to the battery system and offers up to 1.3kW of power output (i.e. you can’t run a bunch of air conditioners off it but it’ll keep a modern fridge up and keep your lights on, run a laptop, charge your phone, run fans, etc.). It will give you a single protected power point – from here, depending on your budget, you can use extension cords and plug boards through your house, run cables to defined backup power points, or even run new cables in your walls to defined power points. Keep in mind that with the current option each power point will be limited to 2.5kW load or 1.3kW with the sonnen 1300.

The device can be retrofitted to all existing sonneBatterie Eco models, which are modular and start at just 2kWh up to 16kWh in the same cabinet. You can chain multiple cabinets together if you need more than that. 

sonnen made the news last year with their ‘free power’ offering via the sonnenFlat service, so this is another great offering from a renewable energy giant (they are the world’s largest home storage battery company)

Sonnen Protect Specifications, Size, Price

  • 15cm wide
  • 19cm high
  • 12cm deep
  • 800grams

Depending on what sort of solution you’d like (with regards to power points and running new wires in the walls), the install for a sonnenProtect 2500 is generally under $1,000 AUD.

If you’re interested in the sonnenProtect for your house please shoot us an email at [email protected] or fill out the form to your right and we’ll be in touch.

sonnen in South Australia – HQ, manufacturing plant.

sonnen in South Australia – the German battery manufacturing giant (which is also the world’s largest home storage energy company) have announced that they’re going to move their Australian headquarters from Sydney to Adelaide. The announcement was made last week during a huge week for renewables in SA – with the upcoming election both major parties have promised $100m in solar loans for South Australian residents.  

sonnen in South Australia

Along with the administrative tasks (i.e. the ‘headquarters’) of sonnen’s Australian operations, they’ll also be setting up a full energy storage manufacturing facility in the state.

Chris Parratt, the Australian boss of sonnen’s Australasian business, said the company will have a solar battery manufacturing facility ‘up and running’ in Adelaide within six to nine months.  According to the Australian Financial Review, Parratt says the facility will be able to produce 10,000 systems a year, including sonnen’s flagship sonnenBatterie line. He noted that they are looking at four separate locations in Adelaide, including the former Holden car manufacturing site and the former Mitsubishi car-making factory in Tonsley Park precinct. 

sonnen in South Australia

Parratt noted that sonnen have set up a similar facility in Atlanta in the United States of America in a fast timeline last year telling a press conference (along with South Australian Premier Jay Weatherill) that they’re confident in scope management:

“We believe in about six to nine months we’ll be producing our first energy storage system,” he said. 

sonnen already have 30,000 household batteries installed in Germany, making them the world’s largest home storage energy company. 

It looks like this will go ahead regardless of whether Weatherill’s incumbent party or the South Australian Liberal leader Steven Marshall wrests control of the state – the latter is against renewable energy targets but has also committed to a $100m means-tested subsidy for up to 40,000 households to get interest free solar loans. 

Weatherill was quick to extol the employment ramifications of the move, having been told he was “doubling down to chase his losses” by federal energy minister Josh Frydenberg last week with regards to raising the RET from 50% to 75%:

“We saw yesterday I was accused of being a problem gambler. Well today, South Australia has hit the jobs jackpot,” Mr Weatherill said, referring to Sonnen’s plans, which will create 130 new immediate jobs, rising to 190 by the end of the year, and then another 300 jobs for trades people to install the batteries.

It’s shaping up to be a very interesting election in South Australia. Who are you voting for, and why? Let us know in the comments.
