This dashboard explores the distribution and growth of residential solar PV installations across Australia, highlighting regional performance and national trends.
Insight: While solar dominates the national landscape, micro-hydro systems find a strong niche in Tasmania (TAS) due to its unique topography and water resources. Conversely, coastal states lead in micro-wind adoption.
Insight: The Diverging Bar Chart highlights the electrification scale. While states like NSW and QLD dominate solar PV (left), NSW is also aggressively leading the transition to energy-efficient air source heat pumps (right).
Insight: By combining installation counts with total capacity data, this Dual-Axis chart reveals whether high-volume areas are simply installing more systems, or adopting larger, more powerful arrays. A spike in the line graph indicates a region investing in heavier commercial/residential capacity.
Insight: This normalized area chart highlights the evolution of the residential battery market. Notice the early dominance of South Australia (SA) around 2016-2018, which has gradually given way to New South Wales (NSW) and Victoria (VIC) as national adoption broadened.
Insight: This 2D Density Heatmap reveals that the vast majority of Australian postcodes cluster tightly in the lower-left quadrant (fewer than 10,000 systems and 50,000 kW capacity). The rare dark outliers stretching toward the top right represent massive urban development zones heavily investing in rooftop solar.
Insight: This Trellis Scatter Plot uses logarithmic scales to handle massive data variance. It reveals the "Renewable Ecosystem" of postcodes: areas with high solar adoption (moving right) often parallel high heat pump adoption (moving up). The bubble size shows that battery storage is still a premium add-on, with noticeable large "Battery Bubbles" heavily concentrated in SA and select NSW postcodes.
Insight: This Dumbbell Plot serves as the conclusion to our analysis. While Australia leads the world in rooftop solar adoption (yellow dots), there is a massive "storage gap." The purple dots show that battery adoption is lagging far behind. The next major phase of Australia's energy transition will not be about generating more power, but storing it.
Bivariate Legend
Insight: This Bivariate Choropleth Map reveals the true storage gap geographically. Dark pink areas indicate postcodes that heavily adopted solar but ignored battery storage. The rare dark blue areas represent the ultimate goal: high adoption of both technologies.
