Atmospheric river cuts irradiance across Western North America
In a new weekly update for pv magazine, Solcast, a DNV company, reports that solar irradiance levels were well below average in western and northern United States in November, while southern parts of the country and Mexico enjoyed strong positive anomalies.
Quantifying uncertainty to produce more useful solar generation forecasts
Renewable energy firm PowerUQ advocates for the use of Uncertainty Quantification (UQ) in solar project analytics to combat the widespread issue of performance shortfalls. By incorporating a wider range of variables and providing probability scenarios like P50 and P90, UQ aims to make solar generation forecasts more useful and accurate over a project’s long lifespan.
Budderfly activates multi-region virtual power plant
The company is now running grid flexibility services for small and mid-sized business customers across the CAISO, NE-ISO, PJM, and SPP independent system operator grids.
Solar risks: Hail, AI error, wildfire, and more
Hail damage remains a top risk to large-scale solar assets, according to an annual report from kWh Analytics.
U.S. solar facilities lost $5,720 per MW to equipment underperformance in 2024
A report from Raptor Maps said solar power losses from equipment failures, extreme weather damage and more contributed to losses.
Christmas Day forecast delivers solar surprises for some
Solcast, a DNV company, reports that, while much of the Americas will see cloudier weather than normal for the season, particularly in the eastern United States and parts of central Brazil, Europe’s solar outlook is split with high pressure over central regions bringing clearer skies to the Iberian Peninsula.
A few micrograms of particulates enough to affect PV power generation
New research from South Korea has shown that even a 10 μg/m3 increase in atmospheric particulate matter can considerably reduce solar power generation and impact revenue of PV system owners.
DNV tool predicts hail probability at future solar sites
DNV, an independent energy expert and assurance specialist, has unveiled a service that assesses the probability of hail events at the site of future solar projects across North America, covering a period up to 30 years.
2024 Outlook: What could La Niña mean for U.S. solar this year?
In a new weekly update for pv magazine, Solcast, a DNV company, describes the possible consequences for PV plan and grid operators of a possible switch to La Niña conditions in North America.
Gulf heat dome and polar set stream shape solar outcomes in May
In a new weekly update for pv magazine, Solcast, a DNV company, reports that a strong polar jet stream and a record-breaking heat dome in May resulted in a stark contrast in irradiance patterns across North America. The western and central USA, along with Mexico, experienced higher than normal irradiance, while the Gulf and East Coast regions faced lower irradiance.
