UNSW study finds bushfire risks to PV assets extend far beyond direct fire damage Australian researchers found that bushfire smoke can reduce solar power generation by up to 70% near fires and by 30% to 40% in areas more than 150 km away. Elevated temperatures during bushfires also accelerate PV module degradation, highlighting the need for improved forecasting, maintenance, and risk management.
