Gawler ranks 277th in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 94 registered systems to date. Growth has been strong, with 6 new systems installed in the past 12 months — a 50% increase on the previous year, making Gawler one of South Australia's faster-growing solar postcodes.
Gawler's solar systems avoid an estimated 425 tonnes of CO₂ per year, equivalent to 202 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.
