Tasman high drives split winter for Australian solar
Solcast, a DNV company, reports that while solar irradiance has been suppressed across eastern Australia this winter, the country’s southern regions have outperformed climatological averages thanks to stable high pressure in the Tasman Sea.
High-pressure systems boost global solar irradiance in early 2025
Solcast, a DNV company, reports that the first half of 2025 has delivered favourable solar conditions across several key solar generation regions around the globe, with many population centres experiencing above-average irradiance.
High pressure ridge splits Australia’s solar output in Autumn
Solcast, a DNV company, reports that irradiance across large portions of eastern Australia fell by up to 20% below the seasonal norm in autumn.
Solar generation faces major disruptions from TC Alfred
DNV company Solcast reports that solar generation in parts of eastern Australia is set to face significant disruptions as Tropical Cyclone Alfred hits the Queensland coast. Other areas may benefit from enhanced solar irradiance due to stabilising atmospheric conditions on the cyclone’s periphery.
Solar gains across Australia defy seasonal cloud forecast
Solcast, a DNV company, reports that Australia’s summer has been much sunnier than expected so far, with localised weather events only bringing brief disruptions.
Cloudier summer predicted for Australia’s east coast solar
Solcast, a DNV company, reports that the upcoming Australian summer is likely to see cloudier than usual conditions, potentially reducing solar generation across key regions, especially along the east coast.
Extreme weather patterns deliver mixed solar results across Australia
Solcast, a DNV company, reports that Australia experienced extreme and diverse weather throughout July and August, resulting in varied impacts on solar irradiance across the country.
Australian solar evades clouds to perform in March
Solcast, a DNV company, reports that Victoria, Tasmania, Western Australia, and New South Wales were over-performing solar regions in March. This overperformance in the southeast and southwest came despite most of the Australian continent seeing below-average irradiance, due to thicker-than-usual clouds over the sparsely-populated interior and tropics.
Winter westerlies drive differences in rooftop solar across eastern Australia
Solar data and forecasting provider Solcast, a DNV company, has detailed the solar irradiance data it collected for Australia in June, showing that eastern New South Wales received irradiance about 15% above normal for the month, while central and western Victoria received totals 10-20% lower than normal.
Solcast sheds light on utility PV performances across Australia
Observations shared by solar data and forecasting provider Solcast have shed new light on the impressive performances of New South Wales solar farms which dominated the utility PV generation performance rankings last month.
