MET file from Global Inc

[AlexMR]

Good evening,

I have real irradiation (Global inc in the collector plane) and temperature data from a pyranometer.

I would like to create a MET file with that values to run a simulation and compare the results with the ones get from different meteo data sources (Meteonorm, NASA, SolarGIS..)

As far as I know MET files needs Global Horizontal and not Global Inc (PVsyst calculates the Inc from the Global Hor using Hay/Perez models). Do I need to do the reverse proccess?

What would be the best way to create that MET file from Global Inc Irradiation and Temperature using PVsyst?

Many thanks for your support.

Kind Regards

Yes you can import POA measured values in PVsyst.

Please use "Databases > Import ASCII meteo Files", and press F1 for the procedure.

The format protocol includes the possibility of reading Global Incident values and PVsyst will perform a retro-transposition.
