Goolwa ranks 164th in South Australia for solar installations — in the middle tier of 347 postcodes tracked by the Clean Energy Regulator across the state. 27 new systems were installed in the past 12 months, a 17% increase on the previous year — steady growth consistent with continued community uptake.
Collectively, Goolwa's 667 solar systems avoid an estimated 3,016 tonnes of CO₂ per year — the equivalent of removing 1,436 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.
