Wollongong ranks 313th in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. 63 new systems were added in the past 12 months, with growth of 2% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Wollongong's 931 solar systems avoid an estimated 8,988 tonnes of CO₂ per year — the equivalent of removing 4,280 cars from the road. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
