Whyalla ranks 223rd in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 250 registered systems to date. Growth has been strong, with 19 new systems installed in the past 12 months — a 27% increase on the previous year, making Whyalla one of South Australia's faster-growing solar postcodes.
Collectively, Whyalla's 250 solar systems avoid an estimated 1,130 tonnes of CO₂ per year — the equivalent of removing 538 cars from the road. 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.
