According to Wikipedia, renewable energy contributed 19.3% to global energy consumption and 24.5% to the generation of electricity in 2015 and 2016, respectively. This has risen sharply in the past couple of years and research indicates that we will continue to speed above and beyond the trillion watts – which is 1 million MW, or a billion kW, if that makes it easier to understand!

Bloomberg New Energy Finance (BNEF) release a report this week which is based on their comprehensive and up-to-date database of renewable energy projects. The report notes that 54% of the renewable energy generated was from wind, and 46% represents solar power. This is interesting as it shows how quickly solar is reaching wind power – in 2007 we had 8GW of capacity (around 8% of the world’s renewable energy) – in comparison to wind power which had 89GW.  According to Renew Economy this represents a gigantic increase of 57x of solar’s 2007 statistics. 

With one terawatt out of the way, Business Green have been crunching the numbers with regards to the second one, which will undoubtedly be far faster and far cheaper than the first:

“The BNEF analysts predict that the pace of renewables rollout will accelerate even more in the coming years, with the second terawatt expected to arrive by mid-2023.”

It looks like wind and solar will produce more power than coal in America within the next 10 years. How will the figures be for the rest of the world? How will Australia go given the future of our National Energy Guarantee is shaky at best (not to mention it’s receiving plenty of criticism in either case). How will solar battery storage affect these figures? Will the huge influx of commercial solar system installations help us reach the next terawatt much faster? Watch this space. It’s going to be an exciting few years for renewable energy!

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

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.

Natural Solar – Blockchain Powered Community Solar

Australian company Natural Solar have advised that they will be using the power of blockchain technology its its latest community solar offering – a new housing development just outside of Sydney which will see 12 homes share power with each other.

Nine are reporting that each home will have a 5kWp solar system and an 8kwh sonnenBatterie 8 installed. Homeowners will be guaranteed up to 20 years of $0 power bills, but they will have a $30 / month bill to sonnenFlat for the program. Power will be shared between the 12 houses and any energy movement will be recorded on the blockchain to record and track the efficacy of of the project. Is 12 houses enough? What happens when it’s 4pm on a Tuesday and 8 houses have air conditioning on? 

If this is a bit complicated to understand, Chris Williams, CEO and Founder of Natural Solar,  explains the concept as a ‘super battery’:

“Utilising Blockchain technology, we are able to join all batteries together to create one larger ‘super-battery’ that can power all homes in one development.

“An advantage of this is for the first time ever in Australia, residents will now be able to borrow power from their neighbours who have excess stored in their own battery, creating a complete sharing economy amongst houses.”

What happens if the energy runs out?

This question was put to Williams who said that, although this model means the developer won’t have to pay for expensive grid upgrades, it’ll still have access at all times: 

“In the event houses need additional power and they can’t borrow extra from their neighbours, they are able to automatically draw this from the grid. If the home is signed up to the sonnenFlat energy plan, this will be free of charge for most houses, provided this fits within their annual electricity consumption.”

The project is set to launch by September – so watch this space and we’ll keep you updated on the progress of Natural Solar’s great project.

South Australian Virtual Power Plant Launched

Tesla’s South Australian Virtual Power Plant has begun deployment, with the first 100 Powerwalls combined with a 5kW solar array rolling out across a group of South Australian households this month. This rollout is in conjunction with the Household Storage Subsidy Scheme in South Australia.

Housing SA are working with Tesla to install the distributed Powerwall tech which is going to start with a focus on public housing and will end up with arrays and Powerwalls/other batteries (read on to learn about the Household Storage Subsidy Scheme) on up to 50,000 homes. 

Another 1,000 South Australian households will have the Tesla batteries installed before July 2019, but potentially ‘in a few weeks’, according to Electrek. Lots of different figures floating around right now so we’ll update you as we hear more.

It’s actually quite similar to the 100MW / 129MWh Powerpack project in that the whole system will help stabilise the grid and provide a strong baseload of power so we don’t see the blackout issues South Australia suffered through in 2016. In this case it’s not one big project, however – many homes working together will decrease cost of electricity and ensure grid stability improves (and continues to). 

There’s also a separate scheme for other battery subsidies – underwritten by the $100 million Household Storage Subsidy Scheme. The push to help renters and low-income earners enjoy the benefits of solar has been fantastic and we’re excited to see some stats and results after the estimated 40,000 SA households receive on average $2,500 each. Please note that this particular scheme is for people who already have solar power installed and want energy storage as well and is not related to the Tesla virtual power plant.

You can watch a video Tesla released about the South Australian Virtual Power Plant – it’ll explain what the plan is and what we can expect to see next from SA and Tesla!

There’s also a video on Twitter from Nine News Adelaide where the current (Liberal) SA state government seem happy to take credit for this scheme (which was totally organised under the previous (Labor) government). Bit of an eye-roll, but then again it’s par for the course for our beloved Australian politicians.

Regardless of that, the tenant in this video had a $500+ bill for electricity every quarter, which has been reduced to $175 since having the solar system installed. So those are some fantastic numbers!

Latrobe Valley solar: 30 public buildings to get PV.

Latrobe Valley solar energy is set to get a boost with 30 public buildings in the area to have rooftop installed at no cost, thanks to a bit of help from the state government in Victoria.

Latrobe Valley Solar Scheme

Energy and environment minister Lily D’Ambrosio was in Moe last week to discuss the scheme and show the Latrobe Valley residents a list of the public buildings in line for free solar upgrades, including in some cases solar hot water and lighting. One such building is the Toongabbie Mechanics Institute – a building where existing solar has already saved $500 on last quarter’s electricity bill. Toongabbie Mechanics Institute treasurer Roger Ries summed it up very succintly:

“It’s made amazing reductions. It’s cheaper for the recreation reserve users and it will make it cheaper for the hall here,” Mr Ries said.

Minister D’Ambrosio spoke about the impact these home solar energy upgrades will have on the lives of lives of 1000 vulnerable Gippslanders.

“The energy upgrades and solar installations will not only help bring down energy prices for the Latrobe Valley, they will create local jobs in the renewable energy sector,” she said.

According to the Latrobe Valley Express, over 1000 households/low incomes earners are also eligible for solar systems as part of the $5 million Latrobe Valley Home Energy Upgrade Program.  Local businesses Gippsland Solar (who are responsible for the fantastic Camberwell Grammar School Solar System), Sunny Afternoons and Rocky’s Electrical will be used for both programs which will create 10 full-time jobs.

There’s been some great solar news for the Latrobe Valley / Gippsland area with regards to both end-user solutions and large-scale renewable energy production – with a 70MW solar farm on the outskirts of Morwell announced back in April, to be build by ARP Australian Solar who said the plant will be a hybrid solar and battery farm which create “well over 100 jobs [during construction]” for the area. 

“There would also be a number of ongoing jobs … involving security, electrical testing, monitoring and what have you.”, according to ARP Australian solar director George Hughes. 

Mr Hughes elaborated on a potential timeline for the Morwell solar farm: 

“With everything going according to plan, we’re looking to start construction in January or February next year, early 2019.”

We’ll keep you updated on both the Latrobe Valley Solar Scheme and the Morwell solar farm. Exciting times for Gippsland!

Lightsource BP offering residential PPAs

Lightsource BP, a UK based solar and smart energy solutions company, is preparing to move into the Australian market where they will offer residential rooftop PV solar power at no upfront cost – instead using the PPA (Power Purchase Agreement) model usually reserved for large-scale solar installs.

Lightsource Labs Australia Pty Ltd (LS Labs) have applied to the Australian Energy Regulator (AER) to launch their product, asking for an individual exemption to hold a retailer authorisation. The application says that LS Labs could launch their product in NSW, SA, QLD, and VIC within a couple of weeks, so all eyes on the regulator to see if they’re happy to grant the exemption.

The way LS Lab’s product will work is that they will supply, install, operate and maintain a solar array, batter and smart metering system to homes, and then sell the renewable power to the client at a fixed price under a PPA model. According to Renewables Now, the period of PPA could be up to 20 years and price per kWh will depend on the terms of each individual contract (i.e. it’ll be cheaper depending on how long the contract is). They also note that customers will be offered the opportunity to buy the system at any time after the second year of the PPA.

RenewEconomy is reporting that Lightsource BP partnered with French company Edf in the UK – using LG Chem batteries as part of the ‘Sunplug’ program. These PPAs were around 9.9p/kWh (~$0.18 AUD) so it’ll be interesting to see how this fares in the Australian market. 

Last month, Lightsource BP acquired Ubiworx Systems to help support a plan for the global launch of a smart-home solution. Kareen Boutonnat, COO of Lightsource BP, said at the time that the “power of the home” will be very important with regards to shaping the world’s “new energy future” – a situation where the energy market transcends monitoring and controlling of consumption, turning ‘smart homes’ into ‘genius homes’ (as we call them). Will be exciting to see where this goes over the next few years!

ACT’s Next Generation Energy Storage Program

The ACT’s Next Generation Energy Storage Program will provide solar batteries to over 5,000 homes and businesses by 2020, offering $25m of funding so ACT residents are able to take advantage of rapidly evolving solar battery technology at a subsidised price.

According to ACT Climate Change Minister Shane Rattenbury there are plans to increase the current amount of storage by up to 36x by 2020: 

“We’ve already had around 400 batteries installed across the city. It’s providing over a megawatt of storage which is both helping households cut their energy bills, manage their own energy usage, but also provide backup for the grid here in the Territory,” he said.

“The battery storage roll-out program is building on Canberra’s reputation as a globally-recognised hub for the renewable energy industry,” Mr Rattenbury was quoted as saying – noting that the program will offer support of up to $825 for each kilowatt of sustained peak output for homes and businesses who install a battery (it can be connected to a new or existing PV solar system). The government estimates that this will represent a subsidy of approximately $4,000 for an average household solar system. 

Six partners have been awarded $3m in grants to help fund the project: ActewAGL Retail, Energy Matters, EPC Solar, Evergen, ITP Renewables, Origin Energy, Power Saving Centre, and Solar Hub. EPC Solar and Evergen were already in the project, the rest are new additions. 

Mr Rattenbury also noted that this project will also help expand the virtual power plant Reposit Power and EvoEnergy are currently trialling: 

“The batteries are also contributing to the world’s largest residential virtual power plant being trialled by Reposit Power and EvoEnergy (formerly ActewAGL Distribution), which allows battery owners to sell their energy to the grid to help support the electricity network.”

Darebin Solar Saver – Interest Free Solar Loans

The Darebin Solar Saver, a groundbreaking solar scheme in the Victorian city of Darebin, means that residents are able to take out an interest-free loan from the council to cover the cost of solar panels and installation, with repayments added to household rates. 

About the Darebin Solar Saver

Darebin councillors signed a $10m contract with EnviroGroup in Northcote to manage the expansion of the Darebin Solar Saver program, with systems available from 2kW to 10kW – installations are set to commence in July 2018. This is in addition to the ~500 households already enjoying the program. 

The $10 million expansion, which will be funded via existing cash reserves, will help further the council’s goal to double solar-power generated in Darebin from 18,000kW to 36,000kW. 

The Herald Sun quoted Kingsbury resident Mai Pham as a very happy user of the Darebin Solar Saver:

“We are really happy with our solar system. We’re saving on our energy bills and it means we don’t need to worry so much,” she said.

“The cost of installing solar means it’s not even a possibility for many low-income families, so this help from the council to cover the initial outlay is such a good idea.”

Residents who would like to take advantage of the generous and forward-thinking solar programs (which are currently slated to run from 2017 – 2021) can click here to register their interest. Alternatively, if you have any questions email [email protected] or phone 8470 8888.

Interest Free Solar Loans

We’ve previously written about interest free solar via Annastacia Palaszczuk’s Labor Party and their ‘Powering Queensland’s Future’ scheme which may be offering no-interest solar loans in Queensland. There are a number of retailers currently offering low/no interest solar deals to customers but to have the purchasing power and safety of the government behind one of these schemes would be an amazing step in the right direction. We’ll keep you updated on any further details for councils subsidising solar for their residents!
