2,719 solar installations registered with the Clean Energy Regulator · ranked top 15% in Victoria · data current as at 2026-08-15
Based on last week's Victoria grid mix (avg 980 gCO₂/kWh), Cowes's 2,719 solar systems typically avoid around 20.38 tonnes of CO₂ every hour during peak generation.

Cowes sits in the top third of Victoria for solar uptake, ranking 92nd in the state out of 713 postcodes in the Clean Energy Regulator dataset. 162 new systems were added in the past 12 months, with growth of 7% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Cowes's solar community avoids an estimated 32,562 tonnes of CO₂ every year — equivalent to taking 15,506 cars off the road or powering around 6,512 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.
