Australia now has more than 9GW of small scale rooftop solar


Australia has broken through another key milestone in small-scale rooftop solar capacity, with 9GW now installed across the country and the 10GW mark likely to be broken by the end of the calendar year.

According to the latest data from Sunwiz, Australia added 156MW of small scale rooftop solar capacity (systems of less than 100kW) in the month of June, taking the year to date total to nearly 1GW, and the grand total to 9.04GW.

“We are about to cross the 1GW threshold for the sub-100kW market, so we’re on track for a 2GW year,” says Sunwiz director Warwick Johnston.


Australia’s emissions surge again, and now well behind Paris trajectory


Australia is falling further behind its Paris emission reduction targets, as the latest emissions estimate from consultancy NDEVR Environmental shows a surge in the first quarter of 2019, increasing the gap between Australia’s emissions and the trajectory that the government insists will be met “in a canter”.

In the first three months of 2019, NDEVR estimates in the latest edition of its ‘Tracking 2 Degrees Report’ that Australia’s emissions jumped by 3.4 million tonnes CO2-e compared to the same period a year prior, or around 2.5%.

The emissions increase was driven by a substantial increase in electricity emissions, which jumped 8.2%, due to a slight fall in renewable electricity and a rise in fossil fuel generation.


Tesla, Fluence to build two big batteries in Victoria


Tesla and Fluence are to build two new big battery storage installations in Victoria after the Australian Renewable Energy Agency contributed an extra $25 million to support Victorian government funding and get the two projects over the line.

Tesla will build a 25MW/50MWh battery to be co-located near the 60MW Gannawarra solar farm near Kerang, while Fluence will build a 30MW/30 MWh grid-connected battery at the Ballarat terminal station.

It is the third major Tesla big battery project in Australian, following the already completed Hornsdale Power Reserve in South Australia that was switched on in December, and the 20MW/34MWh project that will be built next to the Bulgana wind farm near Horsham in Victoria.


“Interest free” loans for solar and storage for South Australia households


The South Australia Labor government continues to push the renewable energy button, offering “interest free” loans to 10,000 households to install rooftop solar and battery storage if it is re-elected in next month’s election.

The initiative, unveiled by Premier Jay Weatherill and energy minister Tom Koutsantonis, will offer the loans to 10,000 homeowners in the state, with no interest charged for the first seven years.

It follows the unveiling of Labor’s new 75 per cent renewable energy target for 2025, along with a 25 per cent “renewable storage” target by the same date, which equates to 750MW of battery, pumped hydro, hydrogen or solar thermal storage.


South Australian government strikes deal with Tesla to install free batteries to 50,000 homes


FREE solar and Tesla batteries will be installed across at least 50,000 homes to create the world’s largest virtual power plant.

THE South Australian Premier Jay Weatherill has inked another deal with Tesla founder Elon Musk for a massive new solar project.

At least 50,000 homes across the state will get a free solar and battery system installed, according to a plan announced on Sunday.

“My government has already delivered the world’s biggest battery, now we will deliver the world’s largest virtual power plant,” Mr Weatherill said.


12 things to know about Tesla’s world’s biggest virtual power plant


The 250MW Tesla virtual power plant in South Australia unveiled on Sunday by the Weatherill state Labor government was impressive for all sorts of reasons.

Firstly, it will be the world’s biggest, in a state that has developed a penchant for having the world’s biggest in something to do with storage – world’s biggest lithium-ion storage facility at Hornsdale, and soon the world’s biggest solar tower with storage in Port Augusta.

Secondly, it accelerates the push towards the future grid, where the market operator, the CSIRO, the networks, and most generators acknowledge will source around half of its electricity needs from local generation, in houses and businesses.


Tesla starts solar roof installations at home of CEO Elon Musk and other employees

sorry sorry

With the release of its second quarter 2017 after market close today, Tesla confirmed that they finally started installing their solar roof tiles in homes – though those homes are owned by their executives and employees.

The company wrote in their shareholders letter sent out today:

“The first Solar Roof installations have been completed recently at the homes of our employees, who we chose to be our first customers to help perfect all aspects of Solar Roof customer experience. By pairing either Solar Roof or our existing retrofit solar panels with a Tesla Powerwall 2, our customers can enjoy sustainable energy independence.”


Is the standalone residential solar inverter obsolete?


When is the last time you removed the side panel of your computer and replaced a network add-in card? When is the last time you installed an inverter on a residential solar system? These are basically the same question, only separated in time. In 2002, the add-in card question would have gotten you an answer; it seems unlikely today. Similarly, in relatively short order, the inverter question fill face the same fate. It’s important to note that the computer add-in card example is not arbitrary; those kinds of devices disappeared for the same reasons that the inverter is about to disappear.

I am the co-founder of an inverter company. Is this view of the inverter heresy?


Australia becomes 35th member of International Solar Alliance.


Launched in Paris during the COP21 summit, the International Solar Alliance, spearheaded by India and France, has this week welcomed Australia to the fold.

The International Solar Alliance (ISA) has swollen to 35 countries this week following the admission of Australia.

The ISA was launched by Indian Prime Minister Narendra Modi and then-French President Francois Hollande at the COP21 UN summit on climate change in Paris in 2015.


Europe Can Increasingly Be A Driver For Tesla Sales $TSLA

The latest figures for sales emphasise the fact that Tesla (NASDAQ:TSLA) is likely to continue to grow exponentially in Europe and Asia. This will happen to EVs in general as ranges increase and prices fall. The prospects for Tesla in the USA are good short term on the back of Model 3 reservations. However, the Trump Administration's anti-environmental approach may have some negative consequences in the medium term. All the major countries in Europe and Asia have signed up for the Paris Climate Accord. The withdrawal of the USA though will probably have a knock-on effect for EV sales there.


Why Tesla's Australian Energy Storage Installation Is Very Likely Just A Humble Beginning

Last Friday, Tesla won a tender to build the world's largest lithium-ion battery, which should help Australia ease its energy crisis. A breakdown of company revenue reveals that energy generation and storage has been the fastest-growing segment in recent years. With dozens of other successful commercial installations, this might be just a humble beginning of a new era for massive energy storage systems. Tesla's pricing makes perfect sense as its primary goal is to gain market share. With falling costs and increasing economies of scale, sooner or later, profits will come.


Tesla Powerpack to Enable Large Scale Sustainable Energy to South Australia


Last September, a 50-year storm damaged critical infrastructure in the state of South Australia, causing a state-wide blackout and leaving 1.7 million residents without electricity. Further blackouts occurred in the heat of the Australian summer in early 2017. In response, the South Australian Government as a leader in renewable energy, looked for a sustainable solution to ensure energy security for all residents, now and into the future, calling for expressions of interest to deploy grid-scale energy storage options with at least 100 megawatts (MW) of capacity. This week, through a competitive bidding process, Tesla was selected to provide a 100 MW/129 MWh Powerpack system to be paired with global renewable energy provider Neoen’s Hornsdale Wind Farm near Jamestown, South Australia.


Energy is the new internet

If you’re not paying attention to what’s going on in energy, you should. We’ve seen this movie before. Spoiler alert: There’s massive economic opportunity ahead. How massive? Imagine standing in 1992, knowing that Google, Akamai, Netflix, Facebook, Amazon, eBay, BuzzFeed and Uber lay ahead.

This time it’s the “enernet,” not the internet, that will transform our lives. The story is the same, though the players have changed.

Here’s the tee up. Across the country, incumbent network providers operate highly centralized networks in their respective cities. Then, scrappy local outfits start serving the market with innovative, distributed technology. These startups create competition, and a new network emerges atop the legacy network.

That was the backdrop 30 years ago when a little thing called the internet emerged. Startups like CompuServe, AOL, EarthLink, Netcom and a host of other local ISPs kicked off the conversion from analog to digital by offering internet access over existing cable and telco networks.


LG Chem unveils new battery storage, adding more choice for solar households


LG Chem, the South Korean company with the biggest share of the grid-connected battery storage market in Australia, has released its new generation systems, promising they will offer more choice, and be cheaper, smaller, lighter, and with improved aesthetics.

LG Chem, which claims nearly half of the nascent but rapidly growing Australian grid-connected market, is offering low voltage and high voltage options to Australian households, with its new battery storage systems ranging from a stack able 3.3kWh lithium-ion system to a 9.8kWh system.

The three low-voltage battery systems (48 volt) are being offered in 3.3kWh, 6.5kWh and 9.9kWh units, while 7kWh and 9.8kWh high voltage (400 volt) battery systems are also being offered.


Why microinverters are a good option for commercial solar projects?

Microinverters have a number of benefits when used in a commercial installation, including increased safety, NEC compliance, comprehensive monitoring, higher energy harvest, and greater reliability than many string inverter options.

Safety and NEC-compliance

Inherent to their design, Microinverters do not require high-voltage DC running across the roof as a string inverter system would. Instead, about 30V DC runs out of the panels into the microinverter and is then converted to AC power—right on the roof. This avoids the very high voltages (600V or higher) that would be running off the roof into a string system. The lower voltages of Microinverters makes the system safer for property owners, emergency responders, and maintenance workers.

How do I know if my solar is actually working?

Some solar owners have no idea how much there solar is producing, or if it is working at all.

According to the clean energy council almost 1.25 million small-scale solar power systems were installed across the country by the end of 2013, meaning that around 3.1 million Australians now live or work beneath a set of solar panels. But how do any of these homeowners actually know if their solar is working?

Solar power is the most beneficial investments that a homeowner can make to power there home, however the type of system and monitoring ability can make a dramatic difference.
