Smart Inverters required under the Victorian Solar Homes Package

Victoria announced some more details of their solar homes package yesterday – and one of the interesting things that came out of this announcement were some specifics on what constitutes a ‘smart inverter’. 

Smart Inverters required under the Victorian Solar Homes Package

Victoria’s Solar Homes Package provides a rebate up to $2,225 or 50% of the price of a solar power system. This is in addition to Australia’s country-wide solar subsidy (STCs). They’re also responsible for solar battery rebates in Victoria and offer an affordable and exciting way to install solar and/or energy storage at your premises. 

“Victorians have been enthusiastic about adopting renewable energy technology, to take charge of their power bills and help protect the environment,” Minister for Solar Homes Lily D’Ambrosio was quoted online as saying. “Ensuring all new systems are equipped with smart inverters will mean we have a more responsive grid that can handle the rapid uptake of renewable energy.”

With the concept of a ‘smart inverter’ being somewhat of a misnomer, in that it’s not really clear what would make an inverter smart. Solar Quotes initially called it a ‘buzzword’, but, with the release of the Government’s Notice To Market, we are now able to discuss the functionalities an inverter will have to have if can be rebated by the Victorian Solar Homes Package:

a) “Enhanced Anti-Islanding”

No inverter is an island. “Normal” anti-islanding refers to turning off the inverter as soon as grid power is lost, as it has the possibility to damage grid equipment and can also be very dangerous for those on the grid trying to fix things up (as it can turn a ‘dead’ power line into something you really don’t want to be working on). A ‘smart inverter’ would have an inverter which complies with international standard IEC 62116, a comprehensive standard to ensure the inverter is able to work well above minimum safety requirements. 

b) Volt-Watt / Volt-Var

These features “facilitate greater penetration of distributed energy sources (DER) by automatically improving power quality”, as per the Victorian Government. This isn’t a major issue as their Notice to Market notes that 95% of inverter installations under the rebate scheme have installed suitable brands with these options, (and, indeed, 95% of the inverters have ‘enhanced anti-islanding’. 

It’s great to get some clarification on this and we’re excited to see how the rest of the solar homes package ends up.

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.

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.

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.

Half price solar for Victorians in $1.2b plan.

Half price solar in conjunction with solar loans will be available to Victorians under a $1.2b plan announced by the state government over the weekend.

Victorian Premier Daniel Andrews announced a $1.24 billion solar plan yesterday. According to the press release the Labor Government released on their website, Victorians will save around $890 / year if they are interested in being part of the half price solar scheme – which involves 50% off solar panels and no upfront cost. The second 50% will be in the form of a solar loan from the government – but to get this loan the Andrews Government will need to be re-elected and implement it from July 2019. 

Premier Andrews has an ongoing argument with the federal government over the National Energy Guarantee – so this is a shot across the bow of Malcolm Turnbull who has recently decided to abolish all energy targets inside the NEG. 

“I can’t give you an answer on the NEG because I don’t know what the NEG actually means, this thing is changing every 24 hours,” Mr Andrews told reporters on Sunday.

 
Not wanting to see a repeat of the pink batts insulation fiasco, an independent agency named Solar Victoria will work with the industry, regulators, and training organisations to ensure the quality of installs is high. Around $9m will be spent to support accreditation of up to 4,500 electricians. Looks like there will be plenty of solar jobs in Victoria if they’re able to get this project over the line.
 
The Victorian Government are hoping to bring solar power to 650,000 households over the next ten years with the Solar Homes program, which they are investing $68m in to launch immediately.
