Join our thriving ecosystem

Australia’s rapid uptake of solar PV technology is driving the transformation of our electricity infrastructure and a robust manufacturing base. Almost half of the 6GW renewables development pipeline in early 2023 is solar. We continue to invest in cutting-edge R&D to speed the transition to net zero.

  • Australia’s national science agency, CSIRO, plays a leading role in coordinating research activity.

    • It leads the Australian Solar Thermal Research Institute (ASTRI), a collaboration with international research institutions, industry bodies and universities. CSIRO and six Australian universities are working closely with partners such as the US’s National Renewable Energy Laboratory, Sandia National Laboratories and Arizona State University on concentrated solar thermal technology to supply cheap, zero-emission and secure energy.
    • CSIRO’s Solar Technologies team leads the way in next-generation solar cells, and concentrated solar thermal (CST) research, and specialises in high-temperature central receiver systems.
    • CSIRO’s Centre for Hybrid Energy Systems is a collaboration hub for researchers and industry in hybrid energy – energy systems that combine two or more energy generation, storage or end-use technologies. One collaboration with Nissan Australia and Delta Electronics on solar-powered electronic vehicle charging is working towards allowing drivers to draw upon renewable energy to charge a vehicle at any time of day, and in any weather, with little impact to the electricity grid.
    • CSIRO envisions an integrated Australian silicon and solar supply chain. Its plan, prepared by PricewaterhouseCoopers, includes the development of end-to-end capability, from quartz mining to manufacturing, end-of-life processes, and recycling, for ‘truly circular’ outcomes.
  • The Australian Centre of Advanced Photovoltaics (ACAP), is headquartered at the University of NSW’s School of Photovoltaic and Renewable Energy Engineering in Sydney. ACAP includes research groups at CSIRO, the Australian National University in Canberra, the Universities of Melbourne and Queensland and Monash University in Melbourne. ACAP has ties with international partners such as Arizona State University’s NSF/DOE Energy Research Center for Quantum Energy and Sustainable Technologies (QESST), The Molecular Foundry at Lawrence Berkeley National Laboratories, Stanford University, Georgia Institute of Technology, and Korea’s Green Energy Institute.
  • Geoscience Australia, the national earth sciences agency, provides pre-competitive solar resource prospectivity data and analysis to support solar industry and research. Its map of active solar ground stations shows where insolation data is currently being collected. It also assesses energy resources to 2030 in its Australian Energy Resource Assessment.
  • Solar also features in several Australian Government-supported and industry-led cooperative research centres (CRCs) including:
  • The Clean Energy Council is the peak body for the clean energy industry in Australia. For a bird’s eye view of large-scale solar projects across Australia, it offers a renewable energy generation project tracker.

Success stories

Multiple global renewables companies have solar PV projects in Australia. They include:

  • The UK’s Lightsource bp, which is poised to become Australia’s largest solar developer. It has five projects in operation or under construction in the states of New South Wales, Queensland and Victoria that total over 1GWp of generating capacity.
  • Italy’s Enel Green Power, which operates three solar plants with 309 MW of installed capacity.
  • France’s ENGIE and Japan’s Mitsui, who are jointly building a A$87 million renewable hydrogen project in Western Australia that includes a 18MW solar PV system
  • France’s Neoen, which has invested more than A$3 billion in Australian renewables across 14 large-scale projects. In December 2022 it started construction on a 200 MW / 400 MWh battery – its fourth big battery in Australia – next to a 460 MWp solar farm it’s building at Western Downs in Queensland. It received financing from the Australian Renewable Energy Agency’s (ARENA) Large Scale Battery Storage Funding Round.  Another Neoen project combines solar energy with sheep farming.
  • Japan’s Sojitz Corporation, which owns the 204 MW Edenvale Solar Park in Queensland.
  • ACEN, listed in the Philippines, has installed almost one million solar panels in stage one of the New England Solar project led by its Australian subsidiary. The 400MW project officially opened in March 2023 within a New South Wales Government’s Renewable Energy Zone (REZ). A second stage will bring the total capacity to 720MW - one of Australia’s largest solar farms. ACEN Australia has more than 1GW capacity in construction, and more than 8GW capacity in the development pipeline. This represents a significant portion of ACEN’s international portfolio.

And commercial-scale concentrated solar power is one step closer in Australia. The Australian Government has approved A$65m funding to Vast Solar to construct a 30 MW / 288 MWh Concentrated Solar Thermal Power (CSP) plant at Port Augusta in South Australia. CSP can be used to generate electricity on demand, including overnight, allowing companies to adjust the power output they supply to the electrical grid. Construction is expected to commence in late 2023.
