In a new weekly update for PV -MagazineSolcast, a DNV company, reports that the registration of radiation in West -Europe stimulated the solar output in May, while low pressure and arctic air suppressed radiation and temperatures in the east.
A stubborn pressure system in Western Europe has led to record-breaking solar circumstances in the United Kingdom and Germany in May, while the east of the continent experienced a grim other experience under low pressure. According to analysis using the Solcast API, the deviations from the irradiation of the record recording in the United Kingdom and have contributed to frequent negative energy prices in Germany, as well as freezing points and widespread cloud that suppresses irradiation in Eastern Europe.
The blocking pattern of May, characterized by a stationary high-pressure system over the United Kingdom, and a northwards, the Polar Jet Stroom distracted, creating a persistent period of warm and cloud-free weather in Western Europe. As a result, the temperatures in the United Kingdom exceed the average May with a maximum of 3 ° C, whereby the surrounding coastal waters up to 4 ° C above normally warms up. This atmospheric stability significantly limited cloud formation, which led to the United Kingdom that has registered more than 30% more irradiation than typically before May. France and Germany also benefited and saw the radiation increase in the reach of 15% to 20%.
The impact on solar generation was considerable. The United Kingdom generated 2.5 TWH of solar energy in May and supplied 11.6% of its total electricity. In the meantime, Germany experienced such a solar surplus that saw negative energy prices two-thirds of the month in the afternoon. These circumstances remained until the high pressure broke at the end of the month and eventually brought rainfall to England in more than a century after the driest spring.
While West -Europa cherished in a clear sky, Eastern Europe died with the opposite pattern. A persistent low -pressure system over the region enabled the Polar Jetstroom to lead Arctic Air in countries such as Poland, White -Russia and Ukraine.
The result was a series of prince in the late season, snowfall and overnight temperatures that fall under the freezing point atypical before May. At some locations, average temperatures were no less than 6 ° C lower than normal. The low pressure also stimulated the formation of thick cloud coverage in the region, so that the irradiation was closed at many locations at only 75% of the season standard.
Solcast produces these figures by following clouds and aerosols with a resolution of 1 km to 2 km worldwide, with the help of satellite data and its own AI/ml algorithms. This data is used to stimulate radiation models, so Solcast is able to calculate the radiation at high resolution, with a typical distortion of less than 2%, and also cloud-tracking predictions. This data is used by more than 350 companies that manage more than 300 GW of solar assets worldwide.
