What This Page Shows

The doughnut chart displays the proportion of installed solar capacity within a selected state or territory, broken down into three main system size categories:

• 0–15kW– Residential-scale systems
• 15–40kW – Small commercial installations
• 40–100kW – Medium commercial systems

Each section is labelled with:

• The number of installations or volume (in kW) for that size segment
• The percentage share of the total installations in that region

This gives a quick overview of the system size profile in any given state.

Filter by State or Territory

You can toggle between:

• National (for an Australia-wide view)
• Individual states/territories (NSW, QLD, VIC, SA, WA, ACT, NT, TAS)

This allows you to explore, for example:

• Which states are still dominated by small residential systems
• Where commercial adoption is gaining traction
• How the system mix changes from region to region

Data Coverage

Please note: all figures reflect installations completed in 2025 under the Small-scale Technology Certificates (STC) scheme. This ensures the most up-to-date and relevant view of current market dynamics.
