Unable to import PVGIS data

When I clicked the import button, an error occurred and I don't know where the problem went. A few days ago, I was still able to use it normally.

We are aware that since December 18th, PVGIS has modified their format for the TMY output, which has affected the functionality of our API call. You can find detailed information about this change in their release notes here:

PVGIS Updates, Bug Fixes, and History.

We are actively addressing this issue, and a fix will be included in our next release, planned for mid-January.

In the meantime, you can use the following workaround to bypass the modified format:

• Open the Databases window and click Known Format.

• Choose PVGISv5 Hourly Time Series Direct Import.

• Define your site by selecting a location from the list or using the interactive map.

• Import the available data from PVGIS by clicking Import. This will generate .MET files for each available year.

Normally you would not run the simulation for a specific year, but an average/typical year based on data from a larger time period. After saving the .SIT file, you have the option to either create a synthetic year based on monthly averages, or to create a typical metrological year – TMY

To create a synthetic year, click on the button "Synthetic gen." and Execute Generation. You can read more about the synthetic data generation in the following help page:
https://www.pvsyst.com/help/physical-models-used/synthetic-data-generation/index.html?h=synthetic+dat

 

To create a TMY, close this window and click TMY generation in the Databases window. In the dropdown list in the top, you can find the site you just created and all the .MET files for the specific years at this site. Pick a Generation method and click Save TMY. You can read about TMY data generation in the following help page:
https://www.pvsyst.com/help/meteo-database/tmy-data-generation/index.html?h=tmy+generation

These files will be saved in your workspace and can be used for simulations as usual.
