Hawker ranks 290th in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 71 registered systems to date. Growth has been strong, with 3 new systems installed in the past 12 months — a 50% increase on the previous year, making Hawker one of South Australia's faster-growing solar postcodes.
Hawker's solar systems avoid an estimated 321 tonnes of CO₂ per year, equivalent to 153 fewer cars on the road annually. This is estimated using South Australia's average grid emissions intensity of 370 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
