1,036 solar installations registered with the Clean Energy Regulator · ranked top 50% in Queensland · data current as at 2026-04-03
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Postcode 4309's 1,036 solar systems typically avoid around 6.42 tonnes of CO₂ every hour during peak generation.

Postcode 4309 ranks 223rd in Queensland for solar installations — in the middle tier of 449 postcodes tracked by the Clean Energy Regulator across the state. Growth has been strong, with 73 new systems installed in the past 12 months — a 33% increase on the previous year, making Postcode 4309 one of Queensland's faster-growing solar postcodes.
The combined impact is substantial: Postcode 4309's solar community avoids an estimated 10,255 tonnes of CO₂ every year — equivalent to taking 4,883 cars off the road or powering around 2,051 average Australian homes with clean electricity. 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.
