Shellharbour is one of New South Wales's strongest solar communities, ranking 51st in the state — ahead of 93% of all New South Wales postcodes tracked by the Clean Energy Regulator. 435 new systems were installed in the past 12 months, a 8% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Shellharbour's solar community avoids an estimated 52,797 tonnes of CO₂ every year — equivalent to taking 25,141 cars off the road or powering around 10,559 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.
