Meteorological data

Choose a source to import meteorological data

  • Closest TMY3 station weather file. (Same as PVWatts® defaults) (Worldwide)
  • 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 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.
