Explore the data
The solar adoption tools and 2026 fleet-age report use dated Clean Energy Regulator source files. Other datasets are added only when their source, geography and limitations can be explained clearly enough to make the numbers useful rather than misleading.
Solar adoption
Explore verified postcode-level installation history and installed capacity from Clean Energy Regulator source files.
Explore solar adoption →System age
Search a Victorian postcode and compare its recorded solar-installation age profile with the broader Victorian 3xxx-postcode aggregate.
Explore system age →Battery adoption
Understand why postcode battery reporting changes from July 2025 and what can be compared reliably.
How battery data is handled →Network & exports
Find the relevant electricity distributor and understand published connection and export rules without generalising one network's settings to another.
Explore network guidance →Equipment
Solar Victoria installation counts by model and brand, clearly limited to installations supported by its rebate and loan programs.
Explore equipment data →Local solar
Use Melbourne suburb guides alongside verified local solar data to understand adoption, system age, network conditions and other area-specific context.

Solar adoption can vary substantially between parts of Melbourne. Our suburb guides bring relevant postcode and area data together with local network, housing and planning context, while making clear when a statistic describes a postcode rather than every home in a suburb.
Primary sources first
Every published statistic points back to a dated source. These are the main datasets used across the data section.

Rules for publishing a number
Useful data is more than a chart. A figure is not published until we can explain what it measures and trace it back to the source.
1. Define it
Geography, period, unit, denominator and whether the value is measured or derived must be explicit.
2. Date it
We keep the source, release date, download date and calculation method so a published figure can be checked later.
3. Challenge it
Postcodes are spot-checked, totals are reconciled where possible, provisional data is flagged and misleading comparisons are withheld.
See how the figures are checked.
The methodology page explains the calculations, known breaks in the data, geographic limits and corrections policy.
