Werribee is one of Victoria's strongest solar communities, ranking 4th in the state — ahead of 99% of all Victoria postcodes tracked by the Clean Energy Regulator. 1,574 new systems were added in the past 12 months, with growth of 6% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Werribee's solar community avoids an estimated 225,696 tonnes of CO₂ every year — equivalent to taking 107,474 cars off the road or powering around 45,139 average Australian homes with clean electricity. This is estimated using Victoria's average grid emissions intensity of 980 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
