Australia Prioritising Ultra-Low-Cost Solar Tech

On behalf of the Australian Government, the Australian Renewable Energy Agency (ARENA) recently announced up to AU$ 40 million in funding to support research and development (R&D) that aims to support the achievement of the Government’s ultra-low-cost solar stretch goal.

The R&D funding round will build on ARENA’s previous R&D investment into solar PV and will seek to support projects that align with ARENA’s Solar 30 30 30 target of 30 per cent module efficiency and 30 cents per installed watt at utility-scale by 2030. ARENA invites applications that can materially reduce the levelised cost of solar PV by 2030 across two streams:

  • Stream 1 – Cells and Modules: Building on Australia’s leading track record of R&D and innovation in solar cells and modules
  • Stream 2 – Balance of system, operations and maintenance: Seeking to broaden the approach to accelerate innovation that can drive down the upfront and ongoing costs of utility-scale solar PV in the field.

ARENA currently expects to allocate up to $20 million in total funding to each of the two streams.

Ultra-low-cost solar was recently added as a priority technology in the Australian Government’s latest Low Emissions Technology Statement (LETS), which set a stretch goal of $15 per megawatt-hour, roughly a third of today’s cost.

Ultra-low-cost solar will be a key input to scaling up production of low-cost green hydrogen, in support of the LETS hydrogen goal of “H2 under $2”, as well as the key to unlocking other decarbonisation pathways for heavy industry including low emission materials such as green steel and aluminium.

As part of ARENA’s new Investment Plan and in support of ultra-low-cost solar, ARENA has set an ambitious target of ‘Solar 30 30 30’, to improve solar cell efficiency to 30 per cent and reduce the total cost of construction of utility-scale solar farms to 30 cents per watt by 2030.

Since 2012, ARENA through its R&D Programs has committed close to $105 million in grant funding to over 70 projects. In addition to this, ARENA has also supported the Australian Centre for Advanced Photovoltaics (ACAP with AU$ 84 million of funding over 10 years.

The CEO of ARENA stated that the pioneering work of Australian solar researchers will be key to driving cost reductions and improving solar cell efficiency.

He noted that Australia’s solar researchers have been leading the world for decades. Thirty years ago, UNSW researchers invented the PERC silicon solar cell, technology which today is the foundation of more than 80% of the world’s solar panels.

That work continues through ACAP, the universities and CSIRO as well as clean energy start-ups. Just a few months ago a start-up founded by former UNSW students and now based in Sydney, created the world’s most efficient solar cell. This AU$ 40 million R&D funding round will support Australia’s solar researchers and industry to get behind the target of Solar 30 30 30 and drive the innovation that will deliver ultra-low-cost solar, he added.

Ultra-low-cost solar will be a vital component in helping Australia move towards a lower cost, largely renewable electricity system and achieve the goal of net-zero emissions by 2050. Expressions of Interest for the Ultra Low-Cost Solar R&D Funding Round will open in February 2022 with applications due by 5 pm AEST Monday 11 April 2022.
