Hervey Bay ranks 255th in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. 46 new systems were added in the past 12 months, with growth of 7% on the previous year — typical of a maturing market where most interested households have already installed.
Collectively, Hervey Bay's 650 solar systems avoid an estimated 6,434 tonnes of CO₂ per year — the equivalent of removing 3,064 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.
