Katoomba ranks 292nd in New South Wales for solar installations — in the middle tier of 721 postcodes tracked by the Clean Energy Regulator across the state. 88 new systems were added in the past 12 months, with growth of 5% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Katoomba's solar community avoids an estimated 10,204 tonnes of CO₂ every year — equivalent to taking 4,859 cars off the road or powering around 2,041 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.
