1,161 solar installations registered with the Clean Energy Regulator · ranked top 50% in Victoria · data current as at 2026-06-15
Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Cowes's 1,161 solar systems typically avoid around 8.70 tonnes of CO₂ every hour during peak generation.

Cowes ranks 227th in Victoria for solar installations — in the middle tier of 713 postcodes tracked by the Clean Energy Regulator across the state. New installations eased in the past 12 months (65 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Cowes's solar community avoids an estimated 13,904 tonnes of CO₂ every year — equivalent to taking 6,621 cars off the road or powering around 2,781 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.
