The electrical output of photovoltaic (PV) systems depends not only on total irradiance and temperature but also on the detailed distribution of photon energies in the incident solar spectrum.

Researchers from HSE University and the Space Research Institute of the Russian Academy of Sciences analyzed seven years of data from the ERG (Arase) satellite and, for the first time, provided a ...

The Sun transports energy from its interior through convection, a process similar to the movement of hot water in a boiling ...

The sun's changing energy levels are not to blame for recent global warming and, if anything, solar variations over the past 20 years should have had a cooling effect, scientists said on Wednesday.

Establishing a key link between the solar cycle and global climate, new research led by the National Center for Atmospheric Research (NCAR) shows that maximum solar activity and its aftermath have ...

After nearly two decades, the Sun has set for NASA's SOlar Radiation and Climate Experiment (SORCE), a mission that continued and advanced the agency's 40-year record of measuring solar irradiance and ...

Brazilian scientists have assessed variations in temperature coefficients in solar modules to determine whether there is a relationship between the dependence of these coefficients and irradiance.

Establishing a key link between the solar cycle and global climate, research led by scientists at the National Science Foundation (NSF)-funded National Center for Atmospheric Research (NCAR) in ...
