Australia’s energy landscape is undergoing a rapid transformation, with new data from the Clean Energy Regulator (CER) confirming record-breaking growth in rooftop solar and household battery installations. The CER’s Q1 2026 Quarterly Carbon Market Report, released on 3 June 2026, highlights a surge of 791 MW in small-scale solar installations during the first quarter, setting a new Q1 record. This unprecedented uptake is coupled with household battery systems now exceeding 420,000 across the nation, boasting over 12 GWh of usable capacity.

This significant acceleration in distributed energy resources is reshaping the National Electricity Market (NEM), providing tangible benefits to consumers and the grid alike. Australia’s commitment to clean energy is evident, with the nation now ranked third globally in combined home and utility-scale battery storage, trailing only China and the United States.

Record Q1 for Small-Scale Solar

The first three months of 2026 saw 791 MW of small-scale solar capacity installed, marking the strongest Q1 performance to date. This figure underscores the continued appetite of Australian households and small businesses for rooftop solar, driven by the desire to reduce electricity bills and contribute to a cleaner energy future. The robust outlook for 2026 suggests this trend is set to continue, with solar installations consistently offsetting growth in electricity demand across the NEM.

For homeowners considering solar, understanding the ongoing value proposition remains crucial. While some rebate structures have seen adjustments, the long-term savings from self-generated electricity continue to make solar an attractive investment.

Home Batteries Surge: Over 420,000 Systems Installed

The adoption of home battery storage has reached new heights, with more than 420,000 systems now installed across Australia, accumulating over 12 GWh of usable capacity. This remarkable growth is largely attributed to the federal government’s Cheaper Home Batteries Program, which has spurred significant investment in energy storage solutions. The CER report indicates that 7.4 GWh of capacity was installed in the first nine months of this program alone.

“As more Australians install solar and batteries, they are changing how they generate, store and use electricity,” said CER Chair David Parker. “The full benefits of this shift will be realised as these technologies become better integrated and able to work together.”

This expansion of household batteries is playing a critical role in shifting renewable electricity from daytime generation to evening peaks, reducing reliance on traditional, often more expensive, grid sources. Minister for Climate Change and Energy Chris Bowen highlighted that batteries more than tripled their daytime-to-evening energy shifting in Q1, actively reducing reliance on coal and putting downward pressure on electricity bills.

Australia’s Global Standing in Battery Storage

The sheer scale of battery deployment has propelled Australia into a leading global position. The nation now ranks third worldwide for combined home and utility-scale battery storage capacity, surpassed only by industrial giants China and the United States. This rapid uptake demonstrates Australia’s unique advantage in leveraging its abundant solar resources with advanced storage technology.

Large-scale renewables approvals and investment also remained strong in the first quarter of 2026, with 1.1 GW approved and 946 MW reaching a final investment decision. Financial investment decisions have already been made on 2.4 GW of new wind and solar projects this year, exceeding 2025 figures just five months in.

Impact on Energy Bills and Grid Stability

The proliferation of rooftop solar and home batteries is directly contributing to lower wholesale electricity prices in Australia’s eastern states. By reducing demand on the grid during peak periods and enabling greater self-consumption of solar energy, households are seeing tangible reductions in their energy costs. The displacement of gas peaking plants and the reduced need for coal-fired generation due to increased battery usage are key factors in this downward pressure on bills.

These developments are not just about individual savings; they are critical for the overall stability and resilience of the NEM. As the Clean Energy Regulator takes on its new role as National Technical Regulator for distributed energy resources, the focus will be on further integrating these technologies to maximise their collective benefits.

Consumers looking to capitalise on these market shifts and further reduce their energy expenditure should regularly review their electricity plans to ensure they are on the most competitive tariffs.

This latest report from the CER paints a clear picture: Australia’s energy transition is not just progressing, it’s accelerating at a world-leading pace, driven by innovative policy and proactive consumer adoption.
