Rockhampton ranks 352nd in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 167 registered systems to date. Growth has been strong, with 6 new systems installed in the past 12 months — a 100% increase on the previous year, making Rockhampton one of Queensland's faster-growing solar postcodes.
Collectively, Rockhampton's 167 solar systems avoid an estimated 1,653 tonnes of CO₂ per year — the equivalent of removing 787 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.
