Australian Solar PV Installation Dashboard visualising residential rooftop solar growth, solar penetration, and adoption trends across Australia to 2025.

Australia continues to lead the world in residential solar photovoltaic (PV) adoption, and the latest update to the MLR Project Management & Consultancy Solar PV Dashboard now includes data up to December 2025. This enhanced dataset provides a more complete picture of national PV uptake, socio‑economic drivers, and regional penetration patterns across all states and territories.

Designed for researchers, academics, government agencies, policymakers, and industry analysts, this dashboard serves as a comprehensive reference tool for understanding the evolution of small‑scale PV installations across Australia. It consolidates verified datasets from the Clean Energy Regulator (CER) and the Australian PV Institute (APVI), offering a reliable foundation for evidence‑based decision‑making, modelling, and policy development.

The Solar PV Dashboard

What This Dashboard Provides

The updated dashboard includes five major analytical components, each designed to support different research and policy needs:

1. Status

A national overview of all installed small‑scale (<100 kW) PV systems from 2001 to 2025, including:

    • Total installed units

    • Installed capacity

    • Monthly and postcode‑level trends

    • Graphical and tabular views for rapid analysis

This section is ideal for researchers tracking long‑term adoption patterns or validating energy transition models.

2. Density

The updated dataset reveals substantial growth in solar adoption between 2022 and 2025.

The dashboard now compares:

    • End of 2022: National density of 32.93%

    • End of 2025: National density of 41.92%

Australia’s residential solar penetration increased by nearly 9 percentage points in just three years, meaning that more than 4 in every 10 Australian households now have rooftop solar installed.

This represents a significant increase in residential solar adoption, with every state and territory showing measurable growth. For example:

    • South Australia increased from 44.03% (2022) to 53.97% (2025)

    • Queensland rose from 40.13% to 50.79%

    • Western Australia grew from 31.91% to 42.68%

These figures highlight the accelerating pace of PV adoption and the growing role of distributed energy resources in Australia’s energy landscape.

3. Time Lapse

A dynamic visualisation showing the evolution of PV installations from 2001 to 2025, where bubble sizes represent total installed capacity. This feature is particularly useful for:

    • Academic presentations

    • Policy briefings

    • Longitudinal studies

    • Renewable energy market analysis

4. Deep Dive

A detailed analytical module offering:

    • Tabular and graphical breakdowns

    • State‑level and postcode‑level insights

    • Forecasting with 95% confidence intervals

This section supports advanced modelling, scenario analysis, and socio‑economic research.

5. Predictor

A statistical model estimating PV penetration at the postcode level based on demographic and socio‑economic variables. This tool is valuable for:

    • Government planning

    • Infrastructure forecasting

    • Academic research on adoption drivers

    • Market segmentation studies

Key Insight: Australia’s Residential PV Penetration Surges to 41.92% by 2025

The most notable update in this release is the jump from 1 in 3 households (2022) to over 40% of households (2025) installing solar PV systems.

This growth is supported by national data trends showing:

  • Continued year‑on‑year increases in rooftop PV capacity

  • Rising average system sizes across states

  • Strong adoption in high‑solar‑resource regions

  • Increased commercial‑scale residential installations in NT, SA, and QLD

These findings align with broader national reports indicating that rooftop solar capacity surpassed 26.7 GW by mid‑2025, with more than 4.15 million systems installed nationwide .

Explore the Dashboard

Whether you are conducting academic research, developing renewable energy policy, evaluating market opportunities, or simply interested in Australia’s energy transition, the Australian Solar PV Installation Dashboard provides a comprehensive and accessible platform for exploring more than two decades of residential solar growth.

Explore the interactive dashboard and discover how rooftop solar has transformed Australia’s energy landscape from 2001 to 2025.
