7,427 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), Mernda's 7,427 solar systems typically avoid around 55.68 tonnes of CO₂ every hour during peak generation.

Mernda is one of Victoria's strongest solar communities, ranking 14th in the state — ahead of 98% of all Victoria postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (467 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Mernda's solar community avoids an estimated 88,944 tonnes of CO₂ every year — equivalent to taking 42,354 cars off the road or powering around 17,789 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.
