The spectral composition of the Sun’s output is not constant but varies over multiple timescales, from days to decadal cycles. Solar spectral irradiance variability (SSI) refers to the changes in the ...

Science writers and news media are invited to a talk at next week’s American Geophysical Union fall meeting to learn about what causes change in the Sun’s powerful activity, from flares that release ...

A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather ...

To mitigate risks, solar industry professionals must adopt better planning strategies and more granular datasets to improve accuracy. Image: Solargis. The financial and technological impact of weather ...

In a new weekly update for pv magazine, Solcast, a DNV company, reports that the global peak of solar output in 2025 occurred ...

Researchers at Columbia University, supported in part by a grant from the U.S. National Science Foundation, conducted a study that modeled the seasonal variability of solar and wind power. The team ...

In a new weekly update for pv magazine, Solcast, a DNV company, reports that the regions with the highest year-to-year variability in irradiance include Central and Northern Europe, East Coast ...

The use of better-quality data can improve the business case for a number of solar projects. Image: Photon Group. The integrity of a PV project largely depends on the quality of the solar, ...
