In a brand-new weekly upgrade for pv publication, Solcast, a DNV business, reports that relentless high pressure in the upper environment resulted in irradiance as high as 30% above typical, and brand-new records for solar generation and temperature level in North America in mid-February.

A warm end to winter season struck the majority of North America this February. In the west, throughout February moderate air from the Pacific banked up clouds and depressed irradiance by 10-20%, according to analysis finished utilizing the Solcast API. In the east, consistent high pressure in the upper environment caused irradiance as high as 30% above typical, and brand-new records for solar generation and temperature level
A clear east/west divide exists in the irradiance anomaly this month. A strong low pressure system sat additional east than typical over the Atlantic which brought calm, drier and warm conditions to the Eastern U.S. and Mexico. Sunnier than regular conditions provided 20-30% more irradiance than regular from Texas to New England. On the west coast nevertheless, high pressure was more west over the Pacific, so that seaside low pressure systems pulled wet air from equatorial areas, resulting in increased clouds, obstructing irradiance.
Clear skies and greater than typical irradiance will have benefited both big and little scale, solar manufacturers. Residential ‘behind the meter’ solar carried out highly this February all over the East Coast. Solcast’s Grid Aggregation design for NYISO reveals domestic solar peaked at 3.52 GW, and saw 23% more solar generation than in 2015 after changing for capability boosts. By contrast, CAISO’s domestic solar generation was down 12% on the long term capacity-adjusted average.
Energy scale generation in ERCOT likewise struck and exceeded their generation peak record, striking 17.2 GW on February 20th. A 50.1% boost in peak generation in February 2023, is primarily a function of capability boosts in the in 2015.

It wasn’t simply grid efficiency breaking current records, temperature level records were broken throughout the nation, with the typical temperature level, more than 4 degrees above regular. Killeen in Texas saw a peak temperature level of 38 C (100 F), and Jacaranda trees in Mexico City have actually remained in maturity all month, 6-8 weeks earlier than typical. In spite of the heat even more south, locations in Eastern Canada saw considerable snowfall brought on by a low pressure system stalling over the location, attracting constant cold air from the Atlantic. This triggered among the heaviest snowfall occasions in twenty years, blanketing parts of Nova Scotia with more than a meter of snow.
This severe weather condition is reflective of a general pattern being seen internationally, as February 2024 was Earth’s hottest month on record for the 9th successive month.
Solcast produces these figures by tracking clouds and aerosols at 1-2km resolution worldwide, utilizing satellite information and exclusive AI/ML algorithms. This information is utilized to drive irradiance designs, making it possible for Solcast to determine irradiance at high resolution,
