Bushfire smoke severely cuts Australian solar farm electricity output

Bushfire smoke can significantly lower electricity generation at solar farms located more than 100 kilometres away from active fires. RenewEconomy reported that researchers from the University of New South Wales published the findings. The study warns solar farm operators across Australia to prepare for indirect smoke impacts alongside direct fire risks. [1]

The researchers estimated that solar power output during severe bushfires drops by up to 70 percent for facilities within 50 kilometres of hotspots. Output drops by up to 40 percent for solar farms located in regions more than 150 kilometres away from the fires. [1]

Smoke contains particulate matter, which consists of microscopic particles of solid or liquid matter suspended in the air. These suspended aerosols can affect regional climate conditions and block sunlight from reaching solar panels. [1][2]

RenewEconomy reported that the University of New South Wales study highlights an urgent need for improved forecasting of smoke movements. The authors also recommended that operators conduct more frequent panel inspections following major fire events. [1]
