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 ...

Photovoltaic module performance and spectral analysis constitute a rapidly evolving field that underpins the optimisation of solar energy conversion systems. Research in this arena focuses on ...

The instrument, the Total and Spectral Solar Irradiance Sensor (TSIS-1), is said to be capable of precisely measuring what researchers call “total solar irradiance”. According to NASA, which has spent ...

Even slight deviations to the equilibrium of this energy system are thought to be capable of causing extreme changes to Earth’s climate. Although solar irradiance data is an important component of ...

NASA has awarded a sole source contract to the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder for the Total and Spectral Solar Irradiance Sensor-2 (TSIS-2).

The recent total solar eclipse over Rochester provided a once-in-a-lifetime opportunity on Earth for two faculty-researchers and their students to capture data about the effects of the sun’s energy ...

This is a preview. Log in through your library . Abstract We present a new climate data record for total solar irradiance and solar spectral irradiance between 1610 and the present day with associated ...

Parts of China saw Global Horizontal Irradiation (GHI) reach 20% more than the long-term average figures in 2025.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that Central Europe, led by Germany, experienced strong solar generation in December due to clear skies from a blocking weather ...
