177 solar installations registered with the Clean Energy Regulator · ranked bottom 50% in Western Australia · data current as at 2026-04-03
Based on last week's Western Australia grid mix (avg 630 gCO₂/kWh), Postcode 6181's 177 solar systems typically avoid around 0.85 tonnes of CO₂ every hour during peak generation.

Postcode 6181 ranks 203rd in Western Australia for solar installations — in the middle tier of 388 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (4 systems, 33% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Postcode 6181's 177 solar systems avoid an estimated 1,363 tonnes of CO₂ per year — the equivalent of removing 649 cars from the road. This is estimated using Western Australia's average grid emissions intensity of 630 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
