How rooftop solar has grown in Victoria.
Explore recorded rooftop-solar installation activity and capacity from the Clean Energy Regulator. Search a Victorian postcode to see its history without pretending postcode totals describe every individual home.
Solar snapshot: Postcode 3136
Source data through 31 August 2026. Current and previous installation years are provisional because Small-scale Technology Certificates can be created for up to 12 months after installation.
What this measures: these figures are recorded Small-scale Renewable Energy Scheme installation events, not a count of unique homes. The CER data includes new systems, upgrades and stand-alone systems.

The chart is a visual summary of the same yearly values shown in the table below. Lighter bars indicate provisional years.

How to read these numbers
An “installation” here is a certificate-backed installation event. Because upgrades are included, it should not be used as a household solar-penetration rate. Average recorded capacity is a derived ratio of rated capacity to installation events; the aggregate source does not support a true median system size.
