PVsyst Sub -hourly Clipping

[Haziq]

Hi, I am in process of applying the sub-hourly clipping and been following the instruction from INSTRUCTIONS FOR PREPARATION OF PAPERS, but i seem stuck at "the first effective line is not a data line, please check the number of header lines"

Which data line should i refer? Do anyone have a video tutorial of enabling the sub-hourly clipping

Hello,

You should define the number of lines to be skipped, before the line where the (sub)hourly data starts. 

The general procedure for importing a custom weather data file is described in the following link:
https://www.pvsyst.com/help/meteo-database/import-meteo-data/custom-meteo-files/conversion-protocol.html

Note that you in this tool are supposed to import a a .csv file with (sub)hourly data, thus one line per time step with irradiance and temperature data and convert the .csv file to a .MET file that you can use in PVsyst to run your simulation.

It seems like your source file is already a .MET file with Meteonorm 8.2 (hourly) data. You cannot re-convert an hourly .MET file to include the clipping correction.
