What is the Small-scale Renewable Energy Scheme?
The Small-scale Renewable Energy Scheme (SRES) is a federal government program that reduces the up-front cost of eligible small-scale renewable energy systems for Australian households and businesses. It works by allowing eligible installations to generate Small-scale Technology Certificates (STCs), which are created at the point of installation and can be assigned to the installer in exchange for a discount on the purchase price. The installer then sells the STCs on the open market, recovering the discount they have passed on to the buyer.
The SRES has operated since 2011 and has historically applied to rooftop solar photovoltaic systems, solar water heaters, and heat pumps. The number of STCs a system generates depends on its size, location, and the number of years remaining in the scheme, which is legislated to reduce annually until the scheme closes in 2030. The point-of-sale discount mechanism means eligible buyers receive the benefit immediately at the time of purchase, rather than waiting to claim a rebate from government after installation.
State and territory governments operate their own separate renewable energy incentive programs, which can operate alongside the federal SRES in some jurisdictions. The federal scheme and state schemes are independent of each other, and eligibility for one does not determine eligibility for the other.

How does the Small-scale Renewable Energy Scheme apply to home batteries?
Home battery systems became eligible for support under the SRES on 1 July 2025, as part of the federal government's Cheaper Home Batteries Program. Before this date, batteries were not covered by the federal scheme, and uptake was driven solely by state-based programs and the commercial case for pairing storage with existing rooftop solar.
What changed on 1 July 2025
Under the expanded SRES, eligible battery installations generate STCs, which create a point-of-sale discount at the time of purchase, reducing the up-front cost of the system. This is the same mechanism that has driven rooftop solar adoption in Australia since 2011. State-based battery incentive schemes remain in place in some jurisdictions and can operate alongside the federal STC discount, depending on the state and the specific program.

How have Australians used the scheme so far?
In the first 10 months of eligibility - July 2025 to April 2026 - Australians installed 392,193 battery systems under the expanded scheme, at a combined installed capacity of 11.2 GWh. The average installed system size was 28.5 kWh. Installation volumes grew across the period, from the opening months of the scheme in mid-2025 through to a record of 68,598 in April 2026.
No equivalent 10-month baseline exists for the period immediately prior to the SRES change, since batteries were not eligible for the federal scheme before 1 July 2025. Year-on-year comparisons will become possible once a second full equivalent period has been recorded under the expanded scheme. The monthly and daily figures published by the Clean Energy Regulator currently provide the clearest available indication of the pace of installation activity.

How many home batteries have been installed in Australia?
Australia recorded 392,193 home battery installations in the 10 months from July 2025 to April 2026, at a monthly average of 39,219 systems. By 2026, the daily installation rate had reached 1,562 systems per day, up from the lower daily rates recorded in the scheme's opening months in the second half of 2025.
National home battery installation figures
Installation volumes were not evenly distributed across the 10-month period. The monthly average of 39,219 masks substantial variation, with the lowest months recorded soon after the scheme's July 2025 start and the highest month - April 2026 - reaching 68,598 installations, 74.9% above the average. This pattern of rising monthly volumes through the period is consistent with a scheme in its early stages, as installer capacity, consumer awareness, and processing pipelines for STCs build over time.

Which months have seen the most home battery installations?
Installation volumes rose over the 10 months to April 2026, with the largest single month-on-month increase - 41% - occurring between January and February 2026. April 2026 then set the record for the period, with 68,598 installations, accounting for 17.5% of all installations recorded across the full 10-month window.
Growth trajectory of battery installations in Australia
The 41% increase between January and February 2026 was the largest month-on-month movement recorded across the 10-month window. This growth built through the first quarter of 2026 and continued into the months that followed, culminating in the April 2026 peak. The trajectory from the scheme's opening months in mid-2025 through to April 2026 shows a period of rising installation volumes rather than a single one-off spike, with only two months (August 2025 and January 2026) recording a decline from the month before.

Australia's biggest month for home battery installations so far
April 2026 recorded 68,598 installations - 74.9% above the 10-month monthly average of 39,219, and equivalent to 17.5% of all installations recorded across the full July 2025 to April 2026 period. This concentration of installations toward the later months of the period is consistent with growing consumer interest in home batteries as awareness of the SRES discount spreads.

What is the total capacity of home batteries installed in Australia?
The 392,193 batteries installed between July 2025 and April 2026 represent 11,167,846 kWh (11.2 GWh) of total installed capacity, at an average system size of 28.5 kWh per household. This capacity has been added in distributed form, spread across hundreds of thousands of individual homes rather than concentrated in a small number of large-scale sites.
Total installed capacity
The 11.2 GWh figure reflects capacity installed under the SRES-eligible period only, and does not include battery capacity installed before 1 July 2025 under state-based schemes. Monthly capacity additions grew across the period, from 513,362.68 kWh in July 2025 to 2,471,936.26 kWh in April 2026.

Average size of battery systems installed in Australia
The average installed system size of 28.5 kWh is generally large enough to cover a household's overnight electricity use in addition to storing solar generation for evening use, though actual coverage depends on individual household consumption. System size varies across the country: the monthly average rose from 17.47 kWh in July 2025 to 36.04 kWh in April 2026, and city and regional averages also differ, at 29.69 kWh and 25.91 kWh respectively.

Geographic patterns
Eight of the top 10 locations - Riverstone, Rouse Hill - Beaumont Hills, Cranbourne South, Tarneit - North, Werribee - West, Baulkham Hills (West) - Bella Vista, Douglas Park - Appin, and Mickleham - Yuroke - are outer metropolitan growth corridor suburbs in NSW and VIC, areas typically associated with new housing construction, high rates of existing rooftop solar, and owner-occupier demographics.
Guanaba - Springbrook, QLD is the exception among the top 10, recording 2,045 installations despite being a non-metropolitan location. Its presence in the national top 10 alongside eight outer-metropolitan growth corridor suburbs makes it the only entry on the list that does not fit the outer-metropolitan pattern.
Combined, the top 10 SA2 locations nationally accounted for 23,951 installations, or 6.11% of the national total of 392,193. The majority of installations are spread across the many thousands of SA2 areas outside the top 10, and no single location or small cluster of locations dominates the national installation count.

How do home battery installation rates compare between cities and regional areas?
Cities recorded more home battery installations than regional areas in the 10 months to April 2026, at 265,675 installations (67.9%) of the classified national total, compared with 125,715 installations (32.1%) in regional areas. Cities also accounted for a larger share of installed capacity, at 7,887,164 kWh compared with 3,257,539 kWh in regional areas.

System size comparison
Average system size differs between cities and regional areas: 29.69 kWh in cities versus 25.91 kWh in regional areas, a gap of 3.78 kWh, or 14.6% larger in cities. City systems account for a larger share of total capacity than their share of installations - 70.6% of the 11.2 GWh national total against 67.9% of installations - a reflection of the larger average system size in cities.
The data shows that cities accounted for a larger share of both installations and capacity than regional areas, and that city systems are larger on average than regional systems.
This split classifies installations by SA2 location against the ABS Greater Capital City Statistical Area structure. A small number of installations (803, or 0.2% of the national total) could not be classified as city or regional, mainly external territories and a small number of unmatched location names, and are excluded from this split but remain part of the national totals.
