Solargis model v2.2.13

The processing of Solargis historical time series (TS) and long-term average (LTA) data were updated and related bugs have been fixed.

Key features:

  • The monthly, yearly and LTA irradiation data were updated from daily average tsums
  • We fixed the yearly PVOUT aggregation previously obtained from daily average, to yearly sums
  • We fixed the UVA, UVA aggregation for monthly and yearly time period
  • We increased the number of decimals in exports for the UVA and UVB as it was insufficient for the winter season
  • We fixed the WOUT aggregation for monthly, yearly sums and LTA
  • We fixed the monthly and yearly experimental uncertainty calculation and changed representation from daily average to sums as well

Wind power forecast

Wind power (WOUT) has been developed and integrated into the standard delivery method of Solargis' forecasts.

This is a preliminary version and we are currently working to release a more developed one.

Key features:

  • Push API enablement for FTP delivery type
  • Access to a global coverage

Solargis model v2.2.12

GOES-R satellite located at 75º West longitude (East location) covering mostly the West coast of continental US and Canada was updated in our historical time series for the period of May to December 2019.

Bug fixes:

Previously, time series data were incorrectly calculated for late afternoon hours for the 1st and last day of the month for the whole period of May to December 2019. It resulted in an underestimation of the cloud coverage for corresponding time series data.

This issue is now fixed in the updated version of our model v2.2.12. All data previously impacted for the west coast of continental US and Canada (approximately 0.5-1%) were correctly recalculated.

Solargis model v2.2.11

Solar radiation data for West Coast of USA and Canada, and Hawaii, for late afternoon hours on first and last day of each month in 2020 was incorrectly calculated, resulting in underestimation of cloud coverage. The issue was fixed and data for all affected days in 2020 was recalculated. Approximately 1% of all 2020 data in the west coast of continental US and Canada, and 2% of 2020 data for Hawaii was affected. Central and Eastern parts of Canada and US were not affected by this issue.

New feature - Blended forecasts

For Europe, forecasts for lead time from 2 hours up to 120 hours is now based on blending of forecasts from 2 NWP models - IFS (ECMWF) and ICON-EU (DWD). In general, IFS is considered as the best performing global NWP model. Yet, we've seen many instances when the IFS forecasts error was quite high. To limit the occurrence of large forecast errors, henceforth a blended forecasts of IFS and ICON-EU models will be used. 

Overall, the new approach is expected to improve accuracy of both intra-day and day-ahead solar power forecasts.

Currently, forecasts from the ICON-EU model is being used only for Europe. We are working on implementation of forecasts of ICON model also for other regions.
