Mount Isa ranks 356th in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 155 registered systems to date. Growth has been strong, with 10 new systems installed in the past 12 months — a 43% increase on the previous year, making Mount Isa one of Queensland's faster-growing solar postcodes.
Collectively, Mount Isa's 155 solar systems avoid an estimated 1,534 tonnes of CO₂ per year — the equivalent of removing 730 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.
