Gawler ranks 229th in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 210 registered systems to date. Growth has been strong, with 14 new systems installed in the past 12 months — a 27% increase on the previous year, making Gawler one of South Australia's faster-growing solar postcodes.
Gawler's solar systems avoid an estimated 950 tonnes of CO₂ per year, equivalent to 452 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.
