Data to Sep 2026. Oct 2025 onward is provisional.
Why recent months are provisional
Installations can be registered with the Clean Energy Regulator up to 12 months after they happen, so figures from Oct 2025 onward will rise as late registrations arrive; earlier months can also be revised. A month-to-month difference is not the number of new systems installed in that month.
