St Kilda ranks 299th in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. 58 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.
Collectively, St Kilda's 669 solar systems avoid an estimated 8,012 tonnes of CO₂ per year — the equivalent of removing 3,815 cars from the road. 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.
