Whittlesea is one of Victoria's strongest solar communities, ranking 30th in the state — ahead of 96% of all Victoria postcodes tracked by the Clean Energy Regulator. 673 new systems were added in the past 12 months, with growth of 7% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Whittlesea's solar community avoids an estimated 61,735 tonnes of CO₂ every year — equivalent to taking 29,398 cars off the road or powering around 12,347 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.
