Australia had established itself as a global leader for solar energy through the installation of record 5.2 gigawatts (GW) of new photovoltaics (PV) system in 2024, which increased total solar capacity across the country to 40 GW — capable of powering more than 20 million homes every year. The achievement was identified in the 2024 Australian PV Power Applications National Survey Report by the International Energy Agency (IEA PVPS), which demonstrated Australia’s swift transformation into a dominant player within the renewable energy sector.
A Surge in Distributed Solar Dominance
There were primarily two areas of growth for solar in 2024: distributed systems accounted for 62% of total installations (3.2 GW) and utility-scale (solar farm) projects added a collective 2 GW. Residential rooftops still form the majority of the growth for solar in Australia as44% of detached homes are now using photovoltaic (PV) systems (over 50% in Queensland and South Australia). The average size of a residential PV system has increased from 6 kW in 2020 to 10 kW today due to improvements in technology and lower prices.
New South Wales (NSW) was the leading state for new residential installations, adding 952 MW; Queensland added 800 MW and Victoria added 582 MW. Together, these three states constitute over 50% of Australia’s total residential solar market.
Policy and Market Dynamics
Australia’s remarkable solar resources (average irradiance of 5.5 kWh/m2) and encouraging laws like tax breaks and state-level subsidies are driving the country’s solar growth. For example, in 2024, more than 50,000 families adopted solar-storage solutions thanks to Victoria’s extended rooftop solar incentive program.
But difficulties still exist:
-
Grid Integration Obstacles: Grid congestion and disjointed approval processes caused numerous utility-scale projects to be postponed despite record installs. Long connecting durations in South Australia and Western Australia resulted in up to 15% higher prices.
-
Regulatory Fragmentation: National deployment is made more difficult by disparate state-level technical requirements for inverters and battery systems. For example, Queensland demands complex communication protocols for grid stability, which foreign manufacturers often struggle to meet.
Technological Innovations
An important change occurred in 2024 with the growth of solar-storage integration. Over 74,500 new battery systems were deployed across the country, with Huawei’s FusionSolar and Tesla Powerwall dominating the market. With Australia’s unstable electricity costs, these devices allow homes to store extra solar energy and lessen their dependency on the grid during peak hours.
Virtual Power Plants (VPPs) have also become popular, especially in South Australia, where 12% of the state’s peak demand is currently met by aggregated residential batteries. Decentralized resources can stabilize grids and provide income for users, as demonstrated by initiatives like Origin Energy’s 500 MW VPP.
Regional Leaders and Challenges
-
Queensland solar installations reached 50% penetration in 2024 (over 1.1 million rooftop systems installed). With its “Solar for Schools” program, educational institutions can receive subsidies for the installation of solar systems, which has further increased the rate at which solar installations are occurring.
-
In contrast, Tasmania is currently limited to 20% solar penetration because of its lower than average irradiance of 3.7 kWh/m2. Due to the intermittent nature of solar power generation, Tasmania is currently piloting hybrid systems that combine solar power and wind energy along with pumped hydro in order to increase reliability and reduce costs.
Future Outlook
Given that the governments are aiming for 40 to 300 GW of electric generation from large public solar projects by the year 2030, it has been projected that the solar power industry in Australia will continue its robust growth. There are a few new developments trending within the sector, including:
-
Agrivoltaics: Combining solar farms with traditional agricultural production to make better use of land; a notable example is the Bungala project, which will produce up to 200 MW of electricity and is located near Bogan Gate in New South Wales.
-
Recycling Infrastructure: Companies like RePower Australia are implementing closed-loop recycling processes to minimize the amount of electronic waste that will result from the inevitable decline of the 14.7 GW of solar panels that will require replacement by 2035.
Conclusion
The success of Australia in solar energy in 2024 is a direct consequence of a mix of Customer Demand, Technological Progress and Government Policy Support; However, these trends cannot continue unless Australia can overcome considerable barriers to the modernization of its electricity Grid and build International Partnerships for Solar Energy Development. As stated by Renate Egan, Lead Author of the IEA National Report, “Solar has transitioned from being Australia’s Future to its Present.”
