Upper Ferntree Gully is one of Victoria's strongest solar communities, ranking 29th in the state — ahead of 96% of all Victoria postcodes tracked by the Clean Energy Regulator. 336 new systems were installed in the past 12 months, a 9% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Upper Ferntree Gully's solar community avoids an estimated 64,597 tonnes of CO₂ every year — equivalent to taking 30,760 cars off the road or powering around 12,919 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.
