Meteorological data

These data is used to calculate shading losses and SOF. PVWATTS and PVGYS dialogs are not related with this meteo files. (PVWATTS and PVGYS dialogs are the same dialogs that you can open using your web browser.)

  • Closest dataset (Same as PVWatts® dialog) or File ID
  • 10k gridded data set from SolarAnywhere TMY2 (Same as NREL solar prospector) (Only USA)
  • TMY2 OR TMY3 file
  • Satel-light file (Europe)

Distance Meteo station - SketchUP model:

Notes:

  • Skelion require diffuse and global hourly horizontal irradiation values to make SOF plots and calculate shading derate.
  • If distance between Meteo station and model location is bigger than 20km it's recommended to use data from satellites.
  • Closest TMY3 station weather file:
    For a system location in the United States, reads TMY3 and TMY2 solar resource data from NREL's National Solar Radiation Database (NSRDB).
    For a system location outside of the United States, PVWatts reads solar resource data from one of the following databases, depending on the location:
    • Solar and Wind Energy Resource Assessment Programme (SWERA)
    • The ASHRAE International Weather for Energy Calculations Version 1.1 (IWEC)
    • Canadian Weather for Energy Calculations (CWEC)
  • 10k gridded data set from SolarAnywhere:
    Only for locations within the United States.
  • Satel-light file:
    Select all years from 1996 to 2000 diffuse and global irradiation to generate the tsv file. Skelion will do a tmy file with the most representative months.
