2,574 solar installations registered with the Clean Energy Regulator · ranked top 25% in Western Australia · data current as at 2026-06-15
Based on last week's Western Australia grid mix (avg 630 gCO₂/kWh), Nedlands's 2,574 solar systems typically avoid around 12.41 tonnes of CO₂ every hour during peak generation.

Nedlands sits in the top third of Western Australia for solar uptake, ranking 71st in the state out of 388 postcodes in the Clean Energy Regulator dataset. 176 new systems were added in the past 12 months, with growth of 3% on the previous year — typical of a maturing market where most interested households have already installed.
The combined impact is substantial: Nedlands's solar community avoids an estimated 19,817 tonnes of CO₂ every year — equivalent to taking 9,437 cars off the road or powering around 3,963 average Australian homes with clean electricity. This is estimated using Western Australia's average grid emissions intensity of 630 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
