Applecross sits in the top third of Western Australia for solar uptake, ranking 45th in the state out of 388 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 322 new systems installed in the past 12 months — a 23% increase on the previous year, making Applecross one of Western Australia's faster-growing solar postcodes.
The combined impact is substantial: Applecross's solar community avoids an estimated 31,549 tonnes of CO₂ every year — equivalent to taking 15,023 cars off the road or powering around 6,310 average Australian homes with clean electricity. 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.
