Hourly output in batch mode (multiple MET files)

[spelland74]

Hello,

I just discovered PVsyst's batch mode and am very happy about this, since it will allow me to run several years of weather data at one time :D

I have been able to use the batch mode successfully when I don't ask for hourly output files to be created. When I ask for hourly output files to be created, I don't get any yearly (or hourly) output for the MET files. Could you explain how to use the batch mode with several MET files and get hourly output for each?

Best regards,

Sophie

When defining the batch mode, you are prompted for defining the variables to be put in your output file.

And in the batch definition (EXCEL) you have to define the name of the CSV file to be created.

Hi Andre,

Suppose I want to use batch mode to simulate several years of weather data. Is it possible to get an hourly output file generated for each of the years of weather data? Or are the outputs only annual when we run the batch mode? I am wondering because in the "parameter specification" tab in batch mode there is a box we can check which reads "Create hourly files". However, I have not been able to get hourly files output for each year.

Best regards,

Sophie

Yes it is possible.

In the EXCEL document, be sure to specify a filename for each hourly file (with extension .CSV)

Hello Andre,

I have tried several times, but haven't been able to generate hourly output files when I run a simulation in batch mode (I do get the annual results though). I will paste below an example of the file I am using to try to generate hourly outputs in batch mode. If you can tell me how I should modify this, it would be much appreciated (note: I can send files by email if this is easier).

Best regards,

Sophie

You have not defined the Filename for each hourly files (*.CSV).

I have named the three files "file1.csv", "file2.csv", "file3.csv". Maybe I am not writing this in the right place?

If you could show me an example of properly written lines to generate hourly batch files, it would be much appreciated. I am having trouble understanding the required format.

[spelland74]

I have now figured it out :)

The lines need to read:

SIM_1; Site_TMY_MOS.MET;file1.csv;First simulation all losses included;;

And so on. I had not understood that the hourly output file name needed to be at that location.

Problem resolved!
