In a new weekly update for <b>pv magazine</b>, Solcast, a DNV company, reports that a persistent high-pressure system over the North Sea created a major April solar irradiance surplus across western and northern Europe by suppressing clouds and boosting GHI well above average. At the same time, displaced storm tracks reduced irradiance in the eastern Mediterranean and parts of Eastern Europe, producing deficits in Greece, Turkey, and Ukraine while maintaining a sharp west–east contrast.
