In a new weekly update for PV -MagazineSolcast, a DNV company, reports that persistent high pressure on Scandinavia has delivered considerably increased irradiation to 30 % above normal in July, while Central and Eastern Europe was confronted with a reduced solar generation under increased cloud covering and rainfall.
In July, persistent high pressure on Scandinavia yielded considerably increased irradiation to 30 % above normal, while Central and Eastern Europe was confronted with reduced solar generation under increased cloud covering and rainfall. Meanwhile, raised increased natural fire smoke from the eastern Mediterranean Sea and the Iberian Peninsula, combined with transcontinental aerosols, clear sky radiation by approximately 5 % in North Europe, according to analysis using the analysis Solcast API.
Over Scandinavia, continuing high pressure yielded on a warm and sunny skies, which improved the generation of solar energy. The irradiation of July exceeded the average values by 10% to 30%, with heat records crushed, including a remarkable 30 C reading in the Arctic Circle in Norway, and an unprecedented 13 -day stripe of 30 ° C temperatures in Finland. These extremes marked the longest warm game on record for that latitude.
At the same time, Turkey registered its highest registered temperature at 50.5 ° C at the end of the month. July 2025 generally arranged as the third -year -old July worldwide, with the global average surface temperatures that run around 1.25 ° C above pre -industrial basic lines. The average surface temperature of Europe was considerably higher than that global average increase, which was considerably contributed to the record -breaking heat observed in July.
Regions through Central and Eastern Europe, including Germany, Austria, Poland, Hungary, the Baltic States and North -Italy,, on the other hand, remained outside the envelope of the high pressure and was always cloudy against the end of the month. These areas registered radiation deficits from 10 % to 30 % below the July standards.
A cold trough in the middle of the judiciary shifted the dynamics drastically for regions that had had early in the heat early in the heat, suddenly confronted with an elevated rainfall and localized floods that aggravated the underperformance of solar energy. For Germany this resulted in the worst July
Record for solar potential. While this decrease in solar potential was bad news for owners of solar assets and operators who want to optimize the performance, on a nets scale, the current pace of increasing solar capacity means that a “bad year” means Solar Weather, Solar in July in July
The power still delivered more than 76.66 GWH to the German grid.
In the meantime, Natuurbroook from South Europe also had an influence on the generation of solar energy. Clear sky radiation in most North European countries ran around 5 % below normal level, even before cloud effects.
This was driven by active fire seasons in South Europe, in particular in eastern Mediterranean regions and on the Iberian Peninsula, which burned about twice as much hectares as in July 2024. Smoke plums of these fires and aerosols from burning Canadian forests that supply input, which is aerosol -lady -load -lady -load -lady -load -lady -load -lady -load -lady -load -load -loading – -load -load -loading -load -loading inuut.
Dissolved Produces these figures by following clouds and aerosols with a resolution of 1-2 km worldwide, using satellite data and 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 300 companies that manage more than 150 GW of solar assets worldwide.
