Australia Q2 2026 rooftop solar hits 1 GW as battery applications pass 500,000

Australia’s Clean Energy Regulator says Q2 2026 delivered 1 GW of rooftop solar, 1.8 GW of large-scale solar reaching FID and more than 500,000 battery program applications.

Large rooftop solar installation

Rooftop solar set a new quarterly record

Australia’s Clean Energy Regulator reported on 28 August 2026 that 1 gigawatt of rooftop solar was installed during the June quarter. The regulator says this exceeded the prior quarterly record of 942 megawatts set in Q4 2023. The figure describes installations recorded in the national scheme during the quarter and is useful evidence of continued distributed-solar activity.

Large-scale solar investment also reached a record

The same Q2 report says 1.8 GW of large-scale solar reached final investment decision during the quarter, the strongest quarterly result since the regulator began tracking that investment measure. Household-scale installations and large project investment therefore both contributed to the quarter’s solar signal.

Battery demand is strong, but applications are not installations

The regulator says it had received more than 500,000 battery applications since the relevant program began. Melnti records this as an application count rather than treating every application as an installed battery. The distinction matters when interpreting market size and service demand.

Melnti interpretation

The data supports continued attention to Australian solar-plus-storage products, installer capability and local battery-program rules. It does not make any product compatible with a specific home or any installer Melnti Verified. Equipment approvals, switchboard design, tariff conditions and current program eligibility still require project-level checks.
