Postcode 4678 ranks 295th in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 393 registered systems to date. Growth has been strong, with 26 new systems installed in the past 12 months — a 44% increase on the previous year, making Postcode 4678 one of Queensland's faster-growing solar postcodes.
Collectively, Postcode 4678's 393 solar systems avoid an estimated 3,890 tonnes of CO₂ per year — the equivalent of removing 1,852 cars from the road. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
