Mordialloc is one of Victoria's strongest solar communities, ranking 36th in the state — ahead of 95% of all Victoria postcodes tracked by the Clean Energy Regulator. 314 new systems were installed in the past 12 months, a 13% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Mordialloc's solar community avoids an estimated 54,322 tonnes of CO₂ every year — equivalent to taking 25,868 cars off the road or powering around 10,864 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.
