South Korean researchers have developed a guided-learning framework that accurately predicts PV power without requiring ...

Solar irradiance is the power per unit area received from the Sun in the form of electromagnetic radiation as measured in the wavelength range of the measuring instrument. The solar irradiance is ...

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 ...

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 ...

In a new weekly update for pv magazine, Solcast, a DNV company, reports that in January most of East Asia experienced normal to above-average solar irradiance, with southeastern China seeing surges ...

A very small instrument has a big job ahead of it: measuring all Earth-directed energy coming from the Sun and helping scientists understand how that energy influences our planet’s severe weather, ...

An approach to improve the performance of floating photovoltaic (FPV) systems by incorporating the complex interplay among ...

East Asia and Europe saw the highest GHI figures, compared to historical averages, in 2025. Image: Solargis. Parts of China saw solar irradiation levels up to 20% higher than the long-term average ...

Maximising the performance of tracked bifacial PV requires optimisation of technical and financial factors. Image: Nextracker PV systems combining bifacial and tracker technologies deliver the ...

In another weekly update for pv magazine, Solcast, a DNV company, reports that a significant reduction in airborne pollutants has contributed to year-to-date irradiance in some parts of China being up ...
