Grid intensity data: Open Electricity (openelectricity.org.au) · 7-day average · updates monthly

Cecil Hills is one of New South Wales's strongest solar communities, ranking 41st in the state — ahead of 94% of all New South Wales postcodes tracked by the Clean Energy Regulator. 421 new systems were added in the past 12 months, with growth of 6% on the previous year — typical of a maturing market where most interested households have already installed.

The combined impact is substantial: Cecil Hills's solar community avoids an estimated 58,078 tonnes of CO₂ every year — equivalent to taking 27,656 cars off the road or powering around 11,616 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.
