Wyong is one of New South Wales's strongest solar communities, ranking 4th in the state — ahead of 99% of all New South Wales postcodes tracked by the Clean Energy Regulator. 1,034 new systems were added in the past 12 months, with growth of 1% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Wyong's solar community avoids an estimated 123,619 tonnes of CO₂ every year — equivalent to taking 58,866 cars off the road or powering around 24,724 average Australian homes with clean electricity. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
