Brunswick Junction ranks 189th 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 (10 systems, 33% below the previous year), a natural slowdown after earlier periods of stronger uptake.
Collectively, Brunswick Junction's 219 solar systems avoid an estimated 1,686 tonnes of CO₂ per year — the equivalent of removing 803 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.
