Oatley ranks 223rd in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. Growth has been strong, with 194 new systems installed in the past 12 months — a 67% increase on the previous year, making Oatley one of New South Wales's faster-growing solar postcodes.
The combined impact is substantial: Oatley's solar community avoids an estimated 16,103 tonnes of CO₂ every year — equivalent to taking 7,668 cars off the road or powering around 3,221 average Australian homes with clean electricity. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
