1,633 solar installations registered with the Clean Energy Regulator · ranked top 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), Postcode 2903's 1,633 solar systems typically avoid around 9.87 tonnes of CO₂ every hour during peak generation.

Postcode 2903 ranks 14th in Australian Capital Territory for solar installations — in the middle tier of 28 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (84 systems, 10% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Postcode 2903's solar community avoids an estimated 15,765 tonnes of CO₂ every year — equivalent to taking 7,507 cars off the road or powering around 3,153 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.
