Murwillumbah is one of New South Wales's strongest solar communities, ranking 40th in the state — ahead of 94% of all New South Wales postcodes tracked by the Clean Energy Regulator. Growth has been strong, with 350 new systems installed in the past 12 months — a 28% increase on the previous year, making Murwillumbah one of New South Wales's faster-growing solar postcodes.
The combined impact is substantial: Murwillumbah's solar community avoids an estimated 58,300 tonnes of CO₂ every year — equivalent to taking 27,762 cars off the road or powering around 11,660 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.
