19,979 solar installations registered with the Clean Energy Regulator · ranked top 5% in Victoria · data current as at 2026-06-15
Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Cranbourne's 19,979 solar systems typically avoid around 149.78 tonnes of CO₂ every hour during peak generation.

Cranbourne is one of Victoria's strongest solar communities, ranking 2nd in the state — ahead of 99% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (1,092 systems, 25% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Cranbourne's solar community avoids an estimated 239,264 tonnes of CO₂ every year — equivalent to taking 113,935 cars off the road or powering around 47,853 average Australian homes with clean electricity. This is estimated using Victoria's average grid emissions intensity of 980 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
