irradiance

Data collection and analysis in solar PV installations is increasingly sophisticated, particularly relating to grid interaction and weather forecasting.

Without quality control, even expensive, high-precision radiometers can generate misleading data, according to Solargis' Marcel Suri.

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

Understanding year-on-year solar radiation variability is critical for optimising solar projects, particularly amid climate change.

Keith McIntosh of PV Lighthouse describes why energy yield forecasts are underestimated, and how the PV industry is improving forecasts.

PV systems combining bifacial and tracker technologies deliver the lowest-cost PV-generated electricity in most parts of the world.

PV modelling relies on the assumption of 99% availability for forecasting, but the adoption of a more realistic metric would improve finances.

Rising pollution in India, is impacting the annual revenue of Indian solar power plants, industry analysts tell PV Tech Premium.

The rapid emergence of new PV technologies such as bifacial has in some cases outpaced the evolution of suitable technical and regulatory specifications.

As PV projects become more and more common in the Nordics, wind players like OX2 are entering the solar market with large-scale projects.
