5,169 solar installations registered with the Clean Energy Regulator · ranked top 10% in New South Wales · data current as at 2026-08-15
Based on last week's New South Wales grid mix (avg 790 gCO₂/kWh), Newcastle's 5,169 solar systems typically avoid around 31.24 tonnes of CO₂ every hour during peak generation.

Newcastle is one of New South Wales's strongest solar communities, ranking 58th in the state — ahead of 92% of all New South Wales postcodes tracked by the Clean Energy Regulator. 398 new systems were installed in the past 12 months, a 11% increase on the previous year — steady growth consistent with continued community uptake.
The combined impact is substantial: Newcastle's solar community avoids an estimated 49,901 tonnes of CO₂ every year — equivalent to taking 23,762 cars off the road or powering around 9,980 average Australian homes with clean electricity. This is estimated using New South Wales's average grid emissions intensity of 790 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
