Australia’s residential solar market continues to expand at pace, supported by high household adoption and growing integration of battery storage systems. The latest data shows approximately 217,000 new rooftop solar systems have been installed over the past 12 months with an estimated 42% of Australian homes now fitted with solar. The country maintains its position as the No.1 globally ranked market for rooftop solar adoption, with an average residential system size of 6.6 kW.

As energy security continues to dominate headlines, Australia is quietly setting records for renewable energy generation.

Australia is in the grip of a record-breaking battery rush. Last week Energy Minister Chris Bowen announced that more than 380,000 home batteries have been installed since July last year. That’s over 100,000 more than the total installed between 2020 and mid-2025. The reason for the rush: government subsidies, which cut the upfront cost by about 30%.

In our collective enthusiasm for renewable energy, Australia now has installed millions of solar panels and inverters on roughly one in three homes. This is one of the most impressive renewable energy stories in the world and a case study in how effective it can be as an investment across the nation.

Australia’s energy transformation is no longer a projection on a policy document — it is actively reshaping the physical landscape of the continent. Across Queensland, New South Wales, Victoria, Western Australia, and South Australia, Renewable Energy Zones are emerging as the structural backbone of a grid that must transition away from ageing coal-fired baseload and deliver clean, reliable, and affordable power to a growing economy.

Construction proper is set to begin on one of Australia’s largest Indigenous-led renewable energy projects after the developer locked in a long-term energy offtake deal with mining giant Rio Tinto.

The Australian government has in its latest Federal Budget stripped almost $2 billion from programs designed to accelerate the rollout of new clean energy systems.

Australian battery technology startup Voltavate will build a new base in Victoria to advance its novel approach to battery manufacturing and accelerate the transition from laboratory development to real-world production.

The proposed inverted perovskite solar cell design reduces band misalignment and electron accumulation, suppressing recombination losses and enabling high efficiency in both small-area devices and scalable modules.

A new report by the International Renewable Energy Agency finds that round‑the‑clock solar and wind paired with battery energy storage deliver power at lower cost than new fossil fuel generation in high‑quality resource regions.

A China-based research team conducted a systematic review and meta-analysis of 147 studies on how solar PV systems alter land surface processes, covering 609 installations worldwide and 11 key climate variables.
