SolarReserve announced on Tuesday that they’ll work with Heliostat SA to create 12,800 96 square metre glass mirrors for their Aurora Solar Thermal Plant. 

The solar thermal plant in Port Augusta, South Australia, was announced last August and received developmental approval back in January It is slated to be a $750m project but we haven’t heard any specifics as to updated pricing, and this information is the first news on the project since January of this year. 

According to the CEO of SolarReserve, Kevin Smith, the solar thermal power plant will comprise of approximately 12,000 mirrors, each the size of a billboard (around 100sqm), arranged in a circle over 600 hectares. The mirrors will focus light and heat to the top of a 227m tall tower to generate up to 150MW. This will result in over a million square metres of surface area for the project. 

“Aurora will provide much needed capacity and firm energy delivery into the South Australian market to reduce price volatility,” Mr. Smith said at the time. He elaborated today when discussing the deal with Heliostat SA: 

“We’re excited to have formed a long-term partnership with Heliostat SA and look forward to teaming up with them to bring manufacturing of our world-class heliostats to South Australian workers,” said Mr. Smith.

“SolarReserve is committed to supporting South Australia’s goals which will attract investment, create South Australian jobs and build an exciting and growing new industry.”

According to an article on RenewEconomy the project will create around 200 full time solar jobs for the area, with 650 to be employed during the construction phase. 

This project is a bit slow and new information is thin on the ground, so great to hear that it’s moving ahead. We’ll keep you posted as soon as there’s any new information on the solar thermal plant!

Solar and Wind Farms in the Sahara Desert

New research in Science magazine shows that installing solar and wind farms in the Sahara Desert could generate massive amounts of electricity and turn parts of the desert green for the first time in over 4,500 years. 

Solar and Wind Farms in the Sahara Desert

The Sahara Desert (source: Wikipedia)

Atmospheric scientist at the University of Maryland, Eugenia Kalnay, has been working on this theory for over ten years, postulating that the darkness of solar panels won’t reflect the sunlight – helping heat up the surface of the land – which will in turn drive air upwards into the atmosphere (which, in turn, generates rain). 

Dr. Kalnay talked one of her post-doc researchers into creating a computer simulation where 20% of the Sahara is covered with solar panels. They also tried a simulation where the desert was covered in turbines to generate renewable energy from wind. The simulation was successful – with rainfall in the desert increasing by a large enough amount so that vegetation could return to the Sahara.

“It is wonderful!” Dr. Kalnay was quoted as saying in an article by NPR. “We were so happy because it seems like a major solution for some of the problems that we have.”

The Sahara Desert solar farm in the simulation is gigantic – bigger than the entire continental United States. It’d be able to generate 400% of the energy the world currently requires. Would there be a way to install high-capacity transmission lines to transport this power across seas and land? It’s certainly a fantastic concept that seems straight out of a science fiction novel, but technology is increasing at such a pace that ideas like this are, whilst admittedly still in nascent stages, potentially viable. 

Take a look at our articles on printable solar panels/cells to see how, if room wasn’t an issue, how much cheaper large-scale solar could be with lower efficiency panels. 

More great information for solar cell technology. Just a thought experiment at this point but it’s exciting to see what the future could hold for renewable energy in the Sahara Desert!

Euroa microgrid: community solar to avoid summer blackouts.

The Euroa Environment Group is leading a $6 million grassroots project which will see 589 kW of new solar panels and up to 400 kW of energy storage installed to create a local Euroa microgrid. This will help avoid the summer blackouts which have plagued the small north-east Victoria city in recent years. 

Euroa Microgrid in combination with Mondo Power and Globird Energy

The EEG (Euroa Environment Group) is a local collective formed to help the issue of constant blackouts in the small city. They’ve now got a huge $6m project which will see the EEG partner with Mondo Power, Globird Energy, and 14 local businesses in Euroa who will install the technology, creating a microgrid in the city which means the town will have greater electricity supply reliability, and will also reduce local demand for electricity during peak times.

The Andrews Labor Government has also given a $600,000 solar grant towards the project, which is currently underway.

Shirley Saywell, president of the EEG and local business owner, has discussed the reasons they’ve taken this path:

“We believe that unfortunately we’re not getting good leadership from our Federal politicians, and I believe it’s up to grassroots organisations to drive the renewables charge,” she said.

“There’s no one simple answer to coal, and I think that’s not well understood.”

“Leadership is coming from groups like ours because we understand there is a range of solutions, and there’s not one simple solution. It’s about being clever about what’s available to us.”

 This sort of community solar is also a hot topic of discussion for Australia’s politicians:

Jaclyn Symes, Member for Northern Victoria, discussed how this could impact future decisions for other towns suffering from unreliable power supply:

“Everyone is becoming more educated around the opportunities and the options for reducing reliance on coal,” Ms Symes said.

“I expect that lots of people will be watching with interest about how this works and what savings people will see, and what types of reliability of power improvements can be generated as well.”

We’ll keep you updated with any news from this microgrid and how it helps Euroa traverse the 18/19 summer.

Bookaar Solar Farm | Timeline, Opposition & More

The $150m, 200MW Bookaar Solar Farm in Victoria is set to start construction in July next year, if local residents trying to scupper the plans don’t have their way.

Bookaar Solar Farm

Bookaar Solar Farm Location
Bookaar Solar Farm Location (source: Google Maps)

The 200MW Bookaar Solar Farm will feature around 700,000 solar panels, according to the ABC. It is located 10 km to the north of Camperdown, in South West Victoria. It’s being developed by Bookaar Renewables Pty Ltd (a partnership between the landowners and Infinergy Pacific)

According to the official website, there are six main reasons they chose that particular location:

  • Good degree of flat land within the land holding.
  • Good solar resource.
  • Simple grid connection options onsite, with capacity on the lines for the required generation size.
  • Extensive farming land.
  • Good transportation links and site access.
  • Low visual impact – they are hoping to add to existing screening by planting a vegetation screen around the perimeter of the solar farm so neighbour views aren’t as obstructed.

During the construction period it is estimated that the project could provide jobs for up to 150 workers over the course of a year and more.  Following this, 12 full time local jobs will be created over the 30 year operational period of the project. 

The project’s Planning Application and Assessments will be submitted to the Corangamite Shire Council in May 2018.  If approved, construction will begin in late 2019 and be completed by late 2019 or early 2020. 

“The development would be operational for 30 years, after which it would be decommissioned and the site returned to its pre-development status,” the application to council states.

With that said, there is still some solar farm opposition due to its planned size.

Bookaar Solar Farm Opposition

The farm is estimated to be around 6 square kilometres in size, in comparison to Camperdown (where the farm will be built near) which is only 4 square kilometres. As a result, some of the residents are a little uneasy about the impact this farm may have on their investments/lives.

Over 30 people turned up to a meeting a fortnight ago where the Boookaar Community Action Group discussed the ‘immense’ size of the project. 

“The clincher is that it’s 605 hectares, over 1500 acres, just by sheer size it’s an immense problem,” Chair of the group Andrew Duynhoven told the meeting.

“The actual solar farm is the size of Camperdown, plus a quarter.

“It’s massive. It’ll probably be the biggest solar farm application in Australia at the moment.”

Dynhoven elaborated that he is pro-solar but the ‘sheer scale’ of the farm is making them nervous:

“I’m not against solar. I’d love to have solar on the dairy, and in the near future that will occur, but I’m against the sheer scale of this.”

Given the small size of Camperdown and the big solar farm, it is more understandable than most solar farm NIMBY opposition. The residents are also concerned about glint, glare, and the classic: using ‘prime agricultural land’ to build a solar farm. 

A public information meeting will be held at the Camperdown botanic gardens at 1pm on Sunday for anyone interested in following this along. Further discussion about the farm can be found on The Standard‘s website.

Darling Downs Solar Update | Jobs, Farms & More

Darling Downs solar is helping the area by providing jobs to locals and kickstarting the economy – with one council already approving $6b worth of wind and solar projects. There’s now a ‘buzz’ around the Darling Downs and renewable energy – let’s take a look at what they have in the pipeline!

“We’ve got $1.2 billion of that under construction now, and that’s the exciting thing, this isn’t just about approvals, this is about action to deliver renewable energies to this region,” Western Downs Regional Council mayor Paul McVeigh said in comments to the ABC

“And we know there are another three [solar farms] in the pipeline.”

In Warwick, the 154,000 megawatt-hour generating UQ / Warwick Solar Farm is to be installed on ‘good agricultural land’ has had to wage a battle against NIMBY detractors. Mayor Tracy Dobie defended her decision (she had the deciding vote to allow the farm DA):

“This region is about growth and development and we can sit here and go poor slowly or we can progress our region and the more development we can get in our region the more jobs,” Ms Dobie said.

“The more progress we can make, the better off we are.”

Mayor Dobie continued to discuss the project and what she sees the future of renewable energy in the Darling Downs as looking like:

“This is a turning point in our region to show we are moving forward, that we are looking to the future, and there is nothing more evident than that than renewable energy.

“There’s a buzz about the Darling Downs, this is a great place to be and great time to be here.”

Toowoomba Solar

There’s been an amazing amount of renewable energy movement in Toowoomba – with the billion dollar project at Bulli Creek approved by the Tooowoomba Council. This will be built by Solar Choice over a 10 year staggered period. 

Toowoomba mayor Paul Antonio spoke about the concerns some residents may have and why he’s happy to continue approving solar farms:

“I guess we have to be a bit cautious of the type of land we put it on, but in saying that, the land is restorable, its not going to be destroyed in any mining effort or anything like that, and in 20, 30, 40 years’ time that land will be back to full production.”

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.

Solar Tarp – foldable, portable solar power.

California based Lipomi Research Group are working on creating a solar tarp – which would have myriad uses for society. Let’s learn more about how these upgraded solar panels could help parts of the world where they don’t have access to regular electricity – and some of the technological challenges they’re facing trying to complete the project.

About the Solar Tarp technology

Prototype Solar Tarp Sample - University of California

The Lipomi Research Group are focused on “identifying ways to create materials with both good semiconducting properties and the durability plastics are known for – whether flexible or not”.  They’ve been tinkering with perovskite solar cells, which are 1/1000 the thickness of a silicon layer in a solar panel. 

Darren Lipomi of the Lipomi Group, who is also a Professor of Nanoengineering at the University of California, said that their goal is to create flexible solar panels which are as efficient as conventional silicon but don’t have some of the drawbacks of it.

The goal is to develop flexible solar panels which are thin, lightweight, and bendable. Lipomi is calling their idea a ‘solar tarp’ – which refers to a solar panel which can be expanded to the ‘size of a room’, but balled up to the size of a grapefruit when not in use. The issues here are finding a molecular structure to make the solar panels stretchable and tough – this involves replacing the silicon semiconductors with materials such as perovskite. 

They’re also taking a look at polymer semiconductors / organic semiconductors (based on carbon, and used in place of perovskites or silicon in a solar cell). These aren’t as efficient, but are far more flexible and extremely durable.

According to The Conversation, the sunlight that hits the earth in a single hour contains more energy than the whole planet uses in an entire year – so there’s plenty more work to do on improving how we utilise the sun! We’ll keep an eye on the solar tarp project and let you know when it reaches the next stage.

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 roads in Tokyo for 2020 Olympics

The Tokyo metropolitan government have announced that they’ll build solar roads in Tokyo which will help Japan promote itself as an eco-friendly nation ahead of the 2020 Olympics and Paralympics. Let’s take a closer look at solar road technology and see how it’s working in other countries as well.

Solar roads in Tokyo

The country has already made some inroads with regards to trialling the solar road technology – in May a car park at a 7-11 in Sagamihara, Kanagawa Prefecture. It consists of solar panels installed on the road, with a covering of a special resin which enhances durability and allows cars/bikes to drive over the panels without damaging them. 

A manager at the 7-11 store was quoted in the Independent as saying: “The solar road system can generate 16,145 kilowatt-hours of electricity annually, covering about nine per cent of the entire electricity that the store consumes.”

Tokyo’s government has set a goal for 2030 – that renewable energy should represent at least 30% of power consumption in the city (up from 12% in 2016).  We’re not sure where the solar roads in Tokyo will go, but we’ll let you know as soon as we have any information.

Business Times reports that it cost around 5 million euro per KM of solar road for the roads already installed in France – so it’s still very expensive and we have a ways to go before solar roads are everywhere.

We reported last year on solar roads in China, which are strong enough for medium-sized trucks to drive over. No news yet on how that is going but we’ve got trials in the Netherlands on cycling roads and also on French motorways so there should be more information on solar road performance soon.

Renovagen commercial-scale portable solar power

UK-based Renovagen has been doing some exciting work in the field of portable solar, with commercial-scale portable solar power systems utilising their ‘rapid roll’ technology recently deployed at Flat Holm, in the UK. They’re also working on rolling out (sorry) this technology on a much larger scale – their “Rapid Roll I” will fit in ISO shipping containers and could be a complete game changer in terms of commercial-scale portable solar power. 

Renovagen’s ‘Solar Carpet’ and Flat Holm

Flat Holm is a small island in the Bristol Channel, five miles off the south Wales coast. Traditionally, providing electricity for it has been a ‘challenge’, according to Flat Holm team leader Natalie Taylor. It has no mains supply and the island has been using old solar panels and diesel generators. 

Gareth Harcombe, energy and sustainability manager at Cardiff Council said: “We were looking at solar and hydro, but that takes up a lot of land and land in cities is expensive. But there is a lot of land that we have that’s available whilst it waits for other opportunities. So this was a question about how we could generate electricity in a way that was portable, so once the site is needed for something else it can be moved on.”

That’s where Renovagen came in – their “rapid roll” roll-up solar panels are providing an average of 11KW of power – enough for four residents and visits from tourists. The system includes batteries capable of storing 24KW/h of power, which is about a day’s worth of the island’s energy requirements. This is a fantastic and cost-effective interim solution until they decide what the optimal choice for Flat Holm’s electricity generation will be.

About Renovagen

John Hingley, Renovagen Managing Director, started work on this scaled-up mobile solar technology in 2012. It’s now the leading UK startup in commercial-scale portable solar power systems. They fully funded a £1,000,000 equity investment pitch via the UK crowdfunding platform, Crowdcube, in April last year – to help the speed up the development and go-to-market costs of their “Roll-Away” rapid roll portable solar systems. The company had hoped to raise £600,000 in equity funding so this was a great result. 

Currently based in Milton Keynes, their technology has been growing in leaps and bounds – take a look at the video below to learn more about how it works:

Rapid Roll Overview Video Presentation Sept 2016 from John Hingley on Vimeo.

Renovagen Rapid Roll “I”

The Renovagen Rapid Roll “I” is one of the most exciting of their products – currently under development, this portable solar power solution will come in an ISO (International Standards Organization or intermodal, i.e. a standardised size) shipping container and can provide enough power (depending on how technology goes, this could be up to 600kWp, according to Renovagen) for a small city. 

The idea of mobile and portable industrial size scale solar power one is extremely exciting and it has a lot of potential uses. The Rapid Roll “I” will fit in 20ft ISO or 40ft ISO containers and will be able to deploy 5x200m and 10x200m of solar panels respectively.

It comes complete with inverters and a large battery bank (specifics not available yet). 

Commercial-Scale Portable Solar Power

There are many uses for commercial-scale portable solar – off grid power in remote locations is extremely expensive and complicated to set up. Military, disaster relief, mining, construction, events, film production, and telecommunications are all situations where this ‘container solar’ idea could provide a huge help at a cost-effective price. 

If they’re able to scale this technology quickly, imagine how useful it’d be in situations like Puerto Rico where Hurricane Maria has left their ravaged state-owned utility PREPA trying frantically to restore power to the island’s 3.4 million residents. Elon Musk and Tesla has stepped in – they’ve been shipping their Powerpack and Powerwall batteries over there and there’s talk of installing a Tesla microgrid in Puerto Rico, but it’ll still be months before grid power is restored to anywhere but places that need it the most urgently (hospitals, authorities, etc.)

This is one of the biggest breakthroughs in portable solar of the past 10 years – so we’ll see what happens in the wake of Flat Holm and keep you updated. Very exciting stuff for solar!
