Weaker monsoon lifts irradiance in Western India as August storms dim the East
India’s 2026 summer monsoon produced sharply contrasting solar conditions. Irradiance increased across major PV-producing regions, while tropical depressions brought cloud, rain and significant deficits farther east.

Sunny north and cloudy south as Super El Niño defines South American winter
The first full El Niño winter since 2015 brought larger irradiance swings across South America and two rare snowfall events in Chile's Atacama Desert that likely affected solar generation.

El Niño transition and a subtropical shift reshape Asia’s summer solar resource
Summer 2026 produced sharply contrasting solar conditions across China. A northward shift in the Western Pacific Subtropical High increased cloud and rainfall in Northeast China, while supporting sunnier conditions and irradiance gains of 20% to 25% across Sichuan, Chongqing and Guizhou.

Despite record U.S. heat in July, North American irradiance remains near average
July 2026 was the hottest month ever recorded in the United States, yet North American irradiance remained close to long-term averages. Wildfire smoke and localized storms offset what could have been a stronger solar resource month.

Partial U.S. eclipse produced similar daily solar energy losses to higher-obscuration European locations
Eclipse timing played an important role in shaping daily solar losses during the 12 August event, while cloud conditions further influenced observed impacts. The study also examined electricity-market responses across Spain, France and New York.
