Key Insights
July 2026 confirms solar's recovery is broad-based and sustained. At +26.4% YoY, it is the fourth consecutive month of positive growth, with all eight states now positive on a rolling 12-month basis for the first time in the dataset. The YoY trend has normalised from April's certificate-catch-up spike into a more credible 20–60% range over May, June and July, suggesting underlying demand is tracking 10–20% ahead of the prior year once lag effects are stripped out. SA (+24.2%), ACT (+25.8%), and NT (+17.8%) continue to lead rolling annual growth.
Western Australia posted the strongest state result in July 2026, with solar up +98.9% YoY (3,991 installs) and battery the most resilient nationally at just -3.6% below its 12-month average. WA now holds 14.4% of the national solar market, up from 11.1% in 2025, and placed three postcodes in the top 10 battery list (Armadale, Mandurah, Success). Perth's outer southern corridor is establishing itself as the most structurally active solar and battery market in Australia on a per-capita basis.
SE Queensland outer suburbs continue to dominate monthly growth, with Manly West (+959%), Cornubia-Carbrook (+762%), and Pinjarra Hills (+450%) all again featuring. These suburbs now appear in the top growth tables for the fifth or sixth consecutive month, confirming that the Brisbane outer-ring retrofit wave is a persistent structural feature rather than a temporary spike. Victoria slipped to -4.5% YoY in July, the only large state in negative territory, with winter seasonality dampening new installs in the cooler months.
Solar YoY Growth Rate Trend
July 2026 at +26.4% is the fourth consecutive positive month, continuing a recovery that began in December 2025. The trend is now clearly established, with all eight states positive on a rolling 12-month basis for the first time since the dataset began.

WA placed four postcodes in the top 10 battery list — Armadale, Mandurah, Success, and Hocking-Pearsall — reflecting the ongoing strength of Perth's outer corridor driven by state rebate programs and a high rate of new residential development. Riverstone (NSW) retains the top battery spot for the third consecutive month, with the Sydney northwest estate corridor consistently producing the highest single-postcode volumes nationally.
Solar Growth, Monthly (Jul 25 to Jul 26)
Manly West (+959%), Cornubia-Carbrook (+762%), and Pinjarra Hills (+450%) again lead. These SE Queensland outer suburbs have now featured in the top growth tables for five or more consecutive months — the Brisbane retrofit wave is a persistent structural feature, not a temporary cluster of installs.
Solar Growth, Annual (2024 to 2025)
Cranbourne South overtook Torquay as the leading annual growth postcode. Victoria's outer new-estate corridors dominate the top 10. The QLD Sunshine Coast hinterland (Nambour, Noosa, Caloundra) is again prominent, driven by sea-change buyer retrofit demand among owner-occupiers.

Methodology and Data Notes
Reporting Period
This report covers July 2026 as the primary reporting month. The August 2026 CER file is used as the data source, but August 2026 figures are excluded as the reporting month given the certificate creation lag.
Certificate Creation Period
The CER allows a 12-month window from installation for system owners to create and register renewable energy certificates. Figures for any given month continue to rise for up to 12 months after closing. The most recent months are materially understated, and year-on-year comparisons should be treated as indicative. The underlying growth rate is likely somewhat lower than headline figures suggest for months within the 12-month creation window.
Battery Baseline
The CER battery dataset commences July 2025, giving 13 months of history as at this report. July 2026 is the first July in the dataset, providing the first like-for-like monthly comparison for battery. The 12-month average will continue to evolve as additional months accumulate.
Geographic Aggregation
Postcode data is mapped to SA2 areas using ABS correspondences. Minor boundary discrepancies may affect individual postcode figures.

Key Insights
June 2026 solar of +51.0% YoY marks the third consecutive month of strong positive growth, continuing the acceleration that began in March 2026. The trend is now clearly established: after 10 consecutive months of negative YoY readings through 2025, the market has firmly shifted into positive territory. June's result sits between April's certificate-catch-up spike (+93.9%) and May's more moderate reading (+15.9%), suggesting the underlying growth rate is settling in the 15–50% range as 2025 registrations continue flowing through. SA posted its strongest ever YoY growth at +100.6%, and QLD led all states in volume at 8,439 installs.
Western Australia reclaimed battery leadership in June 2026 with 6 of the top 10 postcodes, led by Riverstone (NSW, 155), Armadale (WA, 153), and Lockridge-Kiara (WA, 151). Battery nationally at 25,758 is 34.8% below the 11-month average of 39,534, making June the second softest battery month after May. This likely reflects seasonal softness heading into winter rather than a structural shift, as WA's outdoor-friendly climate means its battery market remains more resilient than eastern states in the cooler months.
Queensland dominated the monthly solar growth tables with Manly West (+496%), Cornubia-Carbrook (+1,414%), Ormeau West (+127%), and Shailer Park (+988%) all featuring. These are consistently appearing suburbs across multiple months, confirming the neighbourhood-level retrofit adoption wave in Brisbane's outer ring as a structural phenomenon rather than noise. SA and ACT also recorded strong rolling 12-month growth of +21.6% and +21.7% respectively, the highest of any state on a rolling annual basis.
Solar YoY Growth Rate Trend
June 2026 at +51.0% is the third consecutive month of positive YoY growth, firmly establishing the inflection from the negative run of 2025. The trend from March through June (+36%, +94%, +16%, +51%) shows the market is now running well ahead of the prior year, with some volatility from the certificate lag effect.

WA has reclaimed battery leadership with 6 of the top 10 postcodes. Lockridge-Kiara (6055) is a new entrant at 151 installs — a mid-ring Perth suburb near the airport corridor that has seen strong owner-occupier uptake driven by WA's state battery rebate program. Coomera (QLD, 4209) is a notable entrant at 111, reflecting strong growth in the Gold Coast northern corridor where new estates are increasingly spec-ing battery storage as standard.
Solar Growth, Monthly (Jun 25 to Jun 26)
SE Queensland outer suburbs are again the consistent growth story. Cornubia-Carbrook (+1,414%), Manly West (+496%), and The Hills District postcodes are appearing month after month, confirming a structural retrofit wave rather than one-off spikes. These are owner-occupier suburbs where social diffusion of solar has crossed a visibility threshold.
Solar Growth, Annual (2024 to 2025)
Cranbourne South overtook Torquay as the top annual growth postcode in 2025. Victoria's outer new-estate corridors dominate the top 10, with the QLD Sunshine Coast hinterland (Nambour, Noosa, Caloundra) again the standout outside VIC, driven by sea-change buyer retrofit demand.

Financial Year 2026 in Review
FY26 marks the first full financial year of solar recovery after FY25's sharp 14.6% contraction. National solar installs of 314,337 in FY26 are up 8.9% on FY25's 288,596, recovering roughly 60% of the ground lost in FY25. SA (+21.6%), ACT (+21.7%), and NT (+23.8%) led all states. FY26 is also the first complete financial year on record for battery, with 460,628 installs across 12 months and a monthly average of 38,386.

Methodology and Data Notes
Reporting Period
This report covers June 2026 as the primary reporting month. The July 2026 CER file is used as the data source, but July 2026 figures are excluded as the reporting month given the certificate creation lag.
Certificate Creation Period
The CER allows a 12-month window from installation for system owners to create and register renewable energy certificates. Figures for any given month continue to rise for up to 12 months after closing. The most recent months are materially understated, and year-on-year comparisons should be treated as indicative. The underlying growth rate is likely still positive but somewhat lower than headline figures suggest for months within the 12-month creation window.
Battery Baseline
The CER battery dataset commences July 2025. Only 11 months of history are available as at this report, so monthly average comparisons will continue to stabilise as the dataset grows.
Geographic Aggregation
Postcode data is mapped to SA2 areas using ABS correspondences. Minor boundary discrepancies may affect individual postcode figures.

Key Insights
May 2026 solar growth of +5.7% YoY is a sharp pullback from April's exceptional +86.7%, which was heavily influenced by 2025 certificate registrations catching up through the system. May's more moderate result reflects a return to the underlying trend, which has been gradually recovering from the consistent negative YoY figures seen throughout most of 2025. The 13-month trend shows a clear inflection from December 2025 onwards, with the market now broadly tracking ahead of the prior year.
Western Australia has reclaimed battery dominance in May 2026, placing 6 of the top 10 postcodes nationally, led by Armadale (204), Success (140), Mandurah (125), and Canning Vale (110). This follows April's NSW-dominated result and suggests WA's battery market is structurally active rather than event-driven, with Perth's outer southern suburbs consistently producing high monthly volumes. Battery nationally at 20,126 is well below the 10-month average of 40,513, partly reflecting May as a seasonally softer month.
Southeast Queensland outer suburbs continue to dominate monthly solar growth, with The Hills District postcodes (4054, 4055) up 313% and 625% respectively, and Cornubia-Carbrook and Manly West again featuring. These are established middle-ring Brisbane suburbs experiencing a wave of owner-occupier retrofit solar, driven by neighbourhood social diffusion once adoption rates cross a visible threshold. South Australia posted the strongest state-level YoY growth at +35.4%, and WA at +30.8%, both reflecting genuine underlying demand growth rather than certificate catch-up.
Solar YoY Growth Rate Trend
May 2026 at +5.7% confirms the market has stabilised into positive YoY territory after a sustained negative run through 2025. April's +86.7% was exceptional and driven by certificate catch-up. The underlying trend, visible from the more moderate February and May readings, points to low-to-mid single-digit underlying growth.

WA has reclaimed battery dominance with 6 of the top 10 postcodes in May 2026. Perth's outer southern suburbs (Armadale, Success, Mandurah, Canning Vale) are areas with high rates of new residential development combined with state government battery incentive programs, which together produce consistently high monthly battery volumes. Baldivis and Hocking-Pearsall in Perth's north follow the same pattern. Armadale posting 204 in a single month is the highest single-postcode battery result in the dataset so far.
Solar Growth, Monthly (May 25 to May 26)
SE Queensland middle-ring suburbs are the structural monthly growth story. The Hills District (4054, 4055), Cornubia-Carbrook, and Manly West are established owner-occupier areas where retrofit solar adoption has reached a neighbourhood tipping point, producing sharp clustered upticks each month.
Solar Growth, Annual (2024 to 2025)
Victoria's outer growth corridors remain the structural annual leaders. Cranbourne South and Torquay are new-estate suburbs where developers include solar as standard across large volumes of new homes. The QLD Sunshine Coast hinterland (Nambour, Noosa, Caloundra) reflects sea-change buyer lifestyle-driven retrofit demand.

Methodology and Data Notes
Reporting Period
This report covers May 2026 as the primary reporting month. The June 2026 CER file is used as the data source, but June 2026 figures are excluded as the reporting month given the certificate creation lag (see below).
Certificate Creation Period
The CER allows a 12-month window from installation for system owners to create and register renewable energy certificates. Figures for any given month continue to rise for up to 12 months after closing. The most recent months are therefore materially understated, and year-on-year comparisons should be treated as indicative. The underlying growth rate is likely still positive but lower than headline figures suggest for months within the 12-month creation window.
Battery Baseline
The CER battery dataset commences July 2025. Only 10 months of history are available as at this report, so monthly average comparisons will stabilise as the dataset grows. May 2026 battery figures should be interpreted in the context of a short baseline period.
Geographic Aggregation
Postcode data is mapped to SA2 areas using ABS correspondences. Minor boundary discrepancies may affect individual postcode figures.

Key Insights
April 2026 is the strongest solar month on a year-on-year basis since at least early 2024. The YoY growth rate has accelerated sharply across the first four months of 2026, from -5.0% in January to +8.8% in February, +30.2% in March, and now +70.9% in April. This reverses a sustained run of negative YoY figures throughout 2025, when monthly growth ranged from -4.0% to -31.3% compared to the equivalent 2024 months. The turnaround reflects stronger underlying demand as well as 2025 certificate registrations catching up through the system.
NSW dominated battery installs in April 2026, accounting for 38.4% of national volume and recording a battery-to-solar ratio of 2.30, meaning over two battery systems were registered for every solar system. Riverstone (923 installs) and Rouse Hill (713) are high-growth outer-western Sydney suburbs where master-planned estates are delivering solar and battery as standard builder inclusions across large volumes of new dwellings, producing monthly install figures well above their population size. This northwest and southwest growth corridor has emerged as the structural battery hotspot for 2026.
Southeast Queensland outer suburbs continue to lead monthly solar growth. Cornubia-Carbrook posted +629% growth on April 2025 volumes and Manly West +683%, both established outer-ring suburbs that have reached a critical mass of owner-occupiers upgrading older homes into retrofit solar, which tends to produce sharp, clustered upticks. For longer-run annual trends, Victoria's outer growth corridors (Torquay at +79%, Cranbourne South, Fraser Rise) and Queensland's Sunshine Coast hinterland (Nambour, Noosa, Caloundra) remain the structural leaders in 2024 to 2025 annual growth, driven by new estate development in Victoria and a lifestyle-driven retrofit boom among sea-change buyers on the Coast.
Solar YoY Growth Rate Trend
April 2026 at +70.9% is the highest year-on-year monthly solar growth rate in the dataset going back to 2024, capping a sharp four-month acceleration that reversed more than a year of consecutive negative readings.

Rolling 12-month figures are still influenced by the certificate creation lag in 2025, which suppressed earlier months. The smaller states show positive rolling growth partly because their 2025 months were less affected by the lag.

NSW growth corridors dominate both tables. Riverstone and Rouse Hill are master-planned estate suburbs in Sydney's northwest where volume builders include solar and battery as standard packages across large numbers of new homes, producing monthly install figures well above their population size. Liverpool, The Oaks, and Douglas Park reflect a similar pattern in the southwest corridor, where higher land affordability has driven strong owner-occupier uptake.
Solar Growth, Monthly (Apr 25 to Apr 26)
SE Queensland outer suburbs lead on percentage growth. Cornubia-Carbrook and Manly West are established owner-occupier suburbs that have reached a tipping point of neighbourhood-level solar adoption, producing sharp retrofit-driven upticks.
Solar Growth, Annual (2024 to 2025)
Victoria's outer corridors (Torquay, Cranbourne South, Fraser Rise) are new-estate suburbs where developers include solar as standard, driving volume growth. The QLD Sunshine Coast hinterland (Nambour, Noosa, Caloundra) reflects a lifestyle-driven retrofit boom among sea-change buyers.

April 2026 vs Long-Run Monthly Average
Solar nationally at 35,903 is +60.1% above the long-run monthly average of 22,427 across 183 months (January 2011 to March 2026). Battery at 68,598 is +90.8% above the 9-month average of 35,955 (July 2025 to March 2026). The battery baseline is short so these comparisons will stabilise over time.

Methodology and Data Notes
Data Sources
Solar and battery installation data from the Clean Energy Regulator, Small Generation Unit (SGU) postcode-level dataset. Population and household estimates from the ABS SA2 Estimated Resident Population series.
Certificate Creation Period
The CER allows a 12-month window from the date of installation for system owners to create and register their renewable energy certificates. As a result, figures for any given month continue to rise for up to 12 months after that month closes. The 2025 and 2026 figures in this release are materially understated and will be revised upward in subsequent months. Year-on-year comparisons involving 2025 or 2026 figures should be treated as indicative. The strong positive YoY growth rates seen in early 2026 reflect in part the catching-up of 2025 certificate registrations flowing through the system, and the underlying growth rate is likely still strong but somewhat lower than headline figures suggest.
Battery Baseline
The CER battery dataset commences July 2025. Year-on-year battery comparisons are not available, and the 9-month average used in this report will become more meaningful as additional months accumulate.
Geographic Aggregation
Postcode data is mapped to SA2 areas using ABS correspondences. Where a postcode spans multiple SA2 areas, installs are attributed to the dominant SA2 by population. Minor boundary discrepancies may affect individual postcode figures.
About the data
Where does the data come from?
Every figure comes from the Clean Energy Regulator (CER), the federal body that administers Australia's Small-scale Renewable Energy Scheme. We use the CER's monthly postcode data for small-scale solar systems and home batteries.
How often is the map updated?
Monthly. Each release adds the most recent month the CER has published.
Why is there a two month lag?
System owners have up to twelve months from installation to create and register their certificates with the CER, so recent months keep climbing well after they close. We report on roughly a two month lag and treat the newest months as indicative, so the trends hold up rather than showing understated snapshots.
What counts as an install?
Small-scale solar systems, generally rooftop systems up to 100kW, and home battery systems registered under the scheme. Figures reflect systems that have created certificates with the CER.
Does it cover the whole country?
Yes. The map spans every state and territory at the postcode level. Postcodes are mapped to ABS statistical areas using standard correspondences, so a small number of boundary postcodes may shift slightly.
Are home batteries included?
Yes, using the CER's battery dataset, which begins in July 2025. Because that baseline is still short, battery growth comparisons will settle as more history builds up.
Why might these numbers differ from other sources?
Different trackers cut the data at different dates and treat the certificate creation window differently. Because recent months are still filling in, month on month and year on year figures should be read as indicative rather than final.
