Mount Isa ranks 357th in Queensland out of 449 postcodes in the Clean Energy Regulator dataset, with 152 registered systems to date. Growth has been strong, with 8 new systems installed in the past 12 months — a 33% increase on the previous year, making Mount Isa one of Queensland's faster-growing solar postcodes.
Collectively, Mount Isa's 152 solar systems avoid an estimated 1,505 tonnes of CO₂ per year — the equivalent of removing 717 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.
