Shellharbour sits in the top third of New South Wales for solar uptake, ranking 105th in the state out of 721 postcodes in the Clean Energy Regulator dataset. Growth has been strong, with 244 new systems installed in the past 12 months — a 21% increase on the previous year, making Shellharbour one of New South Wales's faster-growing solar postcodes.

The combined impact is substantial: Shellharbour's solar community avoids an estimated 29,416 tonnes of CO₂ every year — equivalent to taking 14,008 cars off the road or powering around 5,883 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.
