9,033 solar installations registered with the Clean Energy Regulator · ranked top 10% in Queensland · data current as at 2026-05-15
Based on last week's Queensland grid mix (avg 810 gCO₂/kWh), Toowoomba's 9,033 solar systems typically avoid around 55.97 tonnes of CO₂ every hour during peak generation.

Toowoomba is one of Queensland's strongest solar communities, ranking 30th in the state — ahead of 93% of all Queensland postcodes tracked by the Clean Energy Regulator. New installations eased in the past 12 months (531 systems, 17% below the previous year), a natural slowdown after earlier periods of stronger uptake.
The combined impact is substantial: Toowoomba's solar community avoids an estimated 89,412 tonnes of CO₂ every year — equivalent to taking 42,577 cars off the road or powering around 17,882 average Australian homes with clean electricity. This is estimated using Queensland's average grid emissions intensity of 810 gCO₂/kWh, sourced from OpenElectricity, applied to an average system size of 9kW.
