Western wildfires, storms cut solar gains in the West while Eastern US sees boost
September irradiance across North America showed a distinct east–west divide. Wildfires and storm systems reduced solar performance across the western U.S., while clearer, high-pressure conditions boosted irradiance in the East — a pattern expected to persist into autumn.
