Postcode 4378 ranks 348th in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 178 registered systems to date. Growth has been strong, with 30 new systems installed in the past 12 months — a 233% increase on the previous year, making Postcode 4378 one of Queensland's faster-growing solar postcodes.
Collectively, Postcode 4378's 178 solar systems avoid an estimated 1,762 tonnes of CO₂ per year — the equivalent of removing 839 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.
