In a brand new weekly replace for pv journal, Solcast, a DNV firm, experiences that Victoria, Tasmania, Western Australia, and New South Wales have been over-performing photo voltaic areas in March. This overperformance within the southeast and southwest got here regardless of a lot of the Australian continent seeing below-average irradiance, on account of thicker-than-usual clouds over the sparsely-populated inside and tropics.

Australia’s photo voltaic fleet, concentrated within the populated southeast and southwest areas, bucked a nationwide pattern to carry out nicely throughout March. The evaluation, compiled utilizing the Solcast API, consists of forecasts for the final two days of March and confirmed that rooftop and utility-scale photo voltaic carried out nicely on account of above-normal irradiance over the put in photo voltaic of the Nationwide Electrical energy Market (NEM) of the southeast, and the South West Interconnected System (SWIS) of the southwest. The over-performing photo voltaic areas for March in comparison with regular have been Victoria (15% above), adopted by Tasmania (11% above), Western Australia’s SWIS (10% above), and New South Wales (6% above).
This overperformance within the southeast and southwest got here regardless of a lot of the Australian continent seeing below-average irradiance, on account of thicker-than-usual clouds over the sparsely-populated inside and tropics. Photo voltaic efficiency in Queensland and the Northern Territory was down 10% to 30% beneath regular for March.
The reason for the sample of above and beneath regular irradiance throughout March was a predominant climate sample of excessive stress off the east and south coasts of Australia, and monsoonal low stress over the inland and northern tropics. This sample resulted in additional cloud over the tropics and inland, and in prevailing northeasterly winds – making Queensland cloudy however drying air over the opposite populated areas of the southeast and southwest.
The info, which Solcast creates utilizing satellite tv for pc knowledge calibrated to floor measurements, confirmed that the distinction was so stark that farmland photo voltaic zones in New South Wales and Victoria obtained extra complete irradiation for the month than Australia’s “Crimson Centre” inland deserts obtained.

Solcast produces these figures by monitoring clouds and aerosols at 1-2km decision globally, utilizing satellite tv for pc knowledge and proprietary AI/ML algorithms. This knowledge is used to drive irradiance fashions, enabling Solcast to calculate irradiance at excessive decision, with typical bias of lower than 2%, and likewise cloud-tracking forecasts. This knowledge is utilized by greater than 300 firms managing over 150GW of photo voltaic belongings globally.
