TMY 2023 inputs |
Data |
TMY queries now include the whole of 2023 in the input long-term timeseries when generating the synthetic TMY data. |
2024-02-12 |
Himawari-9 cloud calibrations |
Data |
Now that Himawari-9 has been operational over East Asia and Oceania for a sufficient period, we have updated our cloud calibrations over this region. All cloud, radiation and PV power data over the region from 2022-12-13 onwards has been updated and is now more accurate. |
2024-02-06 |
Rooftop Model Panel Backtracking |
Data |
Our Radiation and Weather model across all products now take into account backtracking of solar panels for array_type=horizontal_single_axis, which will give a more physically realistic shape to our GTI. Note that the Advanced PV Power model already includes backtracking and is not affected by this change. |
2024-02-01 |
Improved resolution terrain elevation model |
Data |
We’ve implemented changes to our Digital Surface Model which will enable higher resolution and accuracy. We’ve migrated from Mapzen DEM to the Copernicus DEM. Results retrieved after this change should be considered higher accuracy. |

Dawn/dusk cloud detection update |
Data |
Improved accuracy for Live actuals near dawn/dusk, and for short-range forecasts issued around dawn/dusk. |
2023-05-20 |
New TMY API endpoint |
API |
Probabilistic and 15min and up TMY data now available via API calls. Previously this was only available via manually using the Solcast API Toolkit. See https://docs.solcast.com.au/#2144b738-a1f7-4647-9067-6e7f6eca32a8 |
2023-05-10 |
Historic Eclipses |
Data |
Historic data now includes effects of Eclipses (note that this was already the case for Live and Forecast data). |
