3,596 solar installations registered with the Clean Energy Regulator · ranked top 10% in Victoria · data current as at 2026-05-15
Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Dandenong South's 3,596 solar systems typically avoid around 26.96 tonnes of CO₂ every hour during peak generation.

Dandenong South is one of Victoria's strongest solar communities, ranking 52nd in the state — ahead of 93% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (180 systems, 24% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Dandenong South's solar community avoids an estimated 43,065 tonnes of CO₂ every year — equivalent to taking 20,507 cars off the road or powering around 8,613 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.
