Transformations of data-files

The data files produced by PVsyst are not ASCII files, and have internal coherence constraints which imply that they should never be modified in a text-editor. But the programme proposes some useful transformations such as:

  • Linking two files of same data structure over different periods. Linking is performed at a given fixed date, allowing to manage transitory differences in the accumulation format.
    • For example: passing from summer time to winter time, which should be specified in the parameters of the site during the accumulation, and therefore giving rise to two distinct files during the conversion process.
    • Be aware that PVsyst data files cannot run over 12 months !
  • Merging data, that is introducing one or several parameter data belonging to another internal data file.
    • Example of use: introduction of weather data simultaneously measured by another acquisition system on a very near site.
  • Cut of data according to dates. You can eliminate some given period (integer number of days) from a data file.
    • Tip: You can also use the data elimination tools for hiding faulty data in a file without definitively removing them.
