Whyalla ranks 234th in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 197 registered systems to date. 9 new systems were added in the past 12 months, with growth of 0% on the previous year — typical of a maturing market where most interested households have already installed.
Whyalla's solar systems avoid an estimated 891 tonnes of CO₂ per year, equivalent to 424 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.
