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 ...

South Korean researchers have developed a guided-learning framework that accurately predicts PV power without requiring irradiance sensors during operation, using routine meteorological data instead.

Fluctuations in solar radiation are a problem for solar power plants as they cause problems in the power grid and other reliability issues. In a recent study, scientists aimed to deepen our ...

Graph showing global horizontal irradiance between 2023 and long-term average of yearly totals. Image: Solargis Adequate and suitable solar irradiance data can help solar developers analyse trends of ...

In a new weekly update for pv magazine, Solcast, a DNV company, reports that the first half of 2025 has delivered favourable solar conditions across several key solar generation regions around the ...
