Wanneroo is one of Western Australia's strongest solar communities, ranking 26th in the state — ahead of 93% of all Western Australia postcodes tracked by the Clean Energy Regulator. 269 new systems were added in the past 12 months, with growth of 2% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Wanneroo's solar community avoids an estimated 47,232 tonnes of CO₂ every year — equivalent to taking 22,491 cars off the road or powering around 9,446 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.
