Whyalla ranks 237th in South Australia out of 347 postcodes in the Clean Energy Regulator dataset, with 182 registered systems to date. New installations eased in the past 12 months (7 systems, 71% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Whyalla's solar systems avoid an estimated 823 tonnes of CO₂ per year, equivalent to 392 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.
