1,043 solar installations registered with the Clean Energy Regulator · ranked bottom 50% in Australian Capital Territory · data current as at 2026-05-15
Based on last week's Australian Capital Territory grid mix (avg 790 gCO₂/kWh), Canberra's 1,043 solar systems typically avoid around 6.30 tonnes of CO₂ every hour during peak generation.

Canberra ranks 17th in Australian Capital Territory out of 28 postcodes in the Clean Energy Regulator dataset, with 1,043 registered systems to date. Growth has been strong, with 75 new systems installed in the past 12 months — a 27% increase on the previous year, making Canberra one of Australian Capital Territory's faster-growing solar postcodes.
The combined impact is substantial: Canberra's solar community avoids an estimated 10,069 tonnes of CO₂ every year — equivalent to taking 4,795 cars off the road or powering around 2,014 average Australian homes with clean electricity. This is estimated using Australian Capital Territory's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
