Walgett Solar Farm to supply 50% of UTS solar

Posted on by — No Comments ↓

The University of Technology of Sydney (UTS) has signed a PPA with the Walgett Solar Farm which will cover 50% of its energy usage.

Walgett Solar Farm

The $40m Walgett Solar Farm was approved by the NSW government last year – it will eventually output 32MW and is now reaching the next stage of its project lifecycle.

The farm is owned fully by Epuron, who will be able to commence construction on the project after signing this PPA with UTS.

“For our renewable projects to be able to attract finance and get built, it’s crucial to find suitable partners to become committed customers and provide certainty,” Epuron Director Martin Poole told PV Magazine.

“With the UTS commitment to purchase our clean energy output, the Walgett Solar Farm can move ahead and we look forward to commencing construction in the coming months.” Mr Poole continued.

The project is expected to be built in two stages with the first stage outputting around 15MW.

The Walgett Solar Farm will generate approximately 63,000MWh p.a. once complete – enough to power almost 10,000 homes in New South Wales.

This is the third PPA UTS have signed to add to its renewable portfolio – their main goal, as we wrote last year, is to completely offset their energy usage with renewable energy via a $1.3b ‘City Campus Master Plan’.

“We are committed to finding sustainable solutions to reduce our environmental impact,” UTS Vice-Chancellor Attila Brungs said. “But we don’t just want to create improvement for ourselves, we want to change whole systems to enable others to also improve their sustainability. UTS has spent the last couple of years researching and creating an effective energy model to help reduce emissions while also supporting the continued growth of the renewable energy sector.”

They’ve installed six solar systems on rooftops at the UTS campus and, by 2020/21, are hoping to reduce their emissions 30% on 2007 levels.

Printable Solar Panels / Cells – A Primer.

Printable Solar Panels – at some point it may be possible to use a simple desktop inkjet printer to print your own solar cells. We’re a while off that yet, but with great advancements in the technology over the last couple of years, let’s take a look at what the future holds for printed solar cells!

We wrote last week about the University of Newcastle and their foray into printed solar cells – today we’re going to take a bit of a deep dive into the situation and see where we can expect this technology to go in the next few years. 

The University of Newcastle are reporting that their latest tests in Newcastle brings them “about two years” away from launching their product onto the commercial solar market. Leading the charge has been University of Newcastle physicist Professor Paul Dastoor, who created the electronic inks which are used to print the flexible solar panels.

The process is According to the ABC, semi-conducting ink is printed on a transparent plastic sheet for the first layer, and then layers are printed on top of the other, until the cells are about 200 microns thick. For reference, human hair is around 50 microns. After that, a “top contact layer” is done again, reel-to-reel, using a technique known as sputter coating, according to Professor Dastoor.

They estimate the cost of their modules at less than $10 per square metre which is extremely cheap – the main problems are the efficiency of the printed solar panels and ensuring there’s enough space for them as it’ll take quite a lot of room on a roof. They use a lot of plastic to manufacture as well so looking at ways to recycle the waste of printed solar cells is extremely important. For that reason, in six months Professor Dastoor and his team will pull the printed solar cells off the Melbourne roof they’re currently on and investigate ways to minimise environmental waste.

The University of Newcastle has been able to deliver printed solar cells at a production cost of less than $10 per square metre. They are now powering a Newcastle business and showing results in the wild. Amazing steps forward for solar technology, and in our own backyard! How long until we can print solar cells at home using inkjet printers?

Printed Solar Cells – Breakthrough Technology

University of Newcastle physicist Professor Paul Dastoor has created electronic inks which are used to print the flexible solar panels – offering “unprecedented affordability” and could help solve the energy crises in New South Wales and Australia-wide.

“We are changing the climate, we know it’s because burning fossil fuels and we have to shift to renewables, even if leaders in Canberra can’t understand that,” he told AAP via the Bega District News.

“This technology has the potential to be enormously scalable … it’s fast, it’s low cost and doesn’t require anything special.”

The team are able to print hundreds of metres of solar cells at the Centre of Organic Electronics at the University of Newcastle. If a commercial scale printer were obtained, this could easily be upgraded to kilometres of cells. 

“The low cost and speed at which this technology can be deployed is exciting as we need to find solutions, and quickly, to reduce demand on base-load power – a renewed concern as we approach another summer here in Australia,” Professor Dastoor said.

Around 200 square metres of the printed solar panels has been installed at an industrial site owned by logistics company CHEP in Beresfield, near Newcastle.

This is a fantastic step forwards for solar panel technology People who are wanting to install solar into a rental property or those who don’t have access to a roof (apartment solar) will be licking their lips at the possibility. 

According to Wikipedia, these printed solar cells have a few main drawbacks:

  1. The efficiency of inket solar cells is “too low to be commercially viable” 
  2. Indium is a rare material and could be gone in 15 years.
  3. The ink needs to be weather resistant and can survive harsh conditions.

It looks like the efficiency of Dr Dastoor’s printed solar panels is around 2-3%, but at only A$10 per square metre when manufactured at scale, it looks like these modules are certainly commercially viable, even if they’re not the most efficient cells in the world. 

In six months they will remove the test panels from the CHEP roof and have a look at recycling the material. Professor Dastoor and his team will also run some statistics on how well the printed solar was able to perform. We’ll keep you updated!
