What Is Wildfire Smoke Particle Size (and Why Does It Matter for Solar PV)?
Wildfire smoke particle size refers to the diameter of aerosol particles suspended in smoke plumes, typically measured in micrometers (µm) or nanometers (nm), with the majority ranging from 0.1 to 2.5 µm. These fine and ultrafine particles matter profoundly for photovoltaic professionals because they determine how wildfire smoke scatters and absorbs solar radiation, directly impacting power generation forecasts and system performance across fire-prone regions.
Understanding particle size distribution is no longer optional for solar energy planning. Between 2020 and 2025, wildfire events across North America, Australia, and …
