Whyalla sits in the top third of South Australia for solar uptake, ranking 99th in the state out of 347 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 88 new systems installed in the past 12 months — a 42% increase on the previous year, making Whyalla one of South Australia's faster-growing solar postcodes.
Collectively, Whyalla's 1,870 solar systems avoid an estimated 8,455 tonnes of CO₂ per year — the equivalent of removing 4,026 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.
