Evaluating Accuracy is essential when selecting a solar data provider, make sure you're completing the right level of validation for your needs, and find easy solutions to the challenges of data validation.

High pressure anomalies over the West Coast and Rockies brought solar gains but also worsened wildfire risks. Meanwhile, the Midwest saw solar boosts, while Canada and the Gulf Coast faced cloudier conditions.

Explore how Australia’s summer irradiance outperformed forecasts, as clear skies boosted solar potential and see insights into February’s updated outlook.

Northern Europe faced a gloomy December with solar irradiance 30% below average due to persistent cloud cover, while the Iberian Peninsula and Northern Italy enjoyed up to 30% above-average irradiance.

While the Midwest achieved solar irradiance gains of up to 10% above average in 2024, coastal regions, including California and the Gulf Coast, experienced below-average sunshine due to persistent cloud cover and weather systems.

Despite 2024 being the second hottest year on record, solar irradiance varied significantly across regions. Check the full analysis using the Solcast API.

Solar generation this Christmas will vary widely, with cloudy weather in the Americas, sunshine for Australia, and mixed patterns across Europe and Asia.

Winter storms in Northern Europe drove solar deficits in November, while Southern Europe experienced clear skies, with Italy seeing a 22% solar generation boost.

Despite widespread clouds, Southern Texas, Florida, and the Northeast saw clearer skies, boosting solar generation by 10% above a typical November.
