Rockhampton ranks 403rd in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 49 registered systems to date. Growth has been strong, with 4 new systems installed in the past 12 months — a 300% increase on the previous year, making Rockhampton one of Queensland's faster-growing solar postcodes.
Rockhampton's solar systems avoid an estimated 485 tonnes of CO₂ per year, equivalent to 231 fewer cars on the road annually. 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.
