Importing data from NASA-SSE

• Choose Tools / Geographical site / New, choose the site on the Google map page, and ask "Import" from Nasa-SSE.

Alternatively, you can also find the data directly on the NASA site:

• Go to the NASA site http://eosweb.larc.nasa.gov/sse/
• Click Data Retrieval: Meteorology and Solar Energy
• Enter Latitude and Longitude of your system (or choose on the map)

NB: in the data the conventions are the same as in PVsyst: positive longitudes from Greenwich, toward east.

• Choose:
  • Parameters for sizing Insolation (average, Min and Max)
    • Meteorology: Air temperature (at 10m)
    • Eventually: Wind speed at 50m

NB: we do not recommend to use these wind data for estimating Module temperatures in the simulation.

Then you can print these data, and you should enter them manually as a new geographic site.
