Importing actual weatherstation data on to PVsyst

[Sydwell]

Good day,

We have a site which has been operational for a few months and we have a weatherstation installed.

We would like to use the data from the weatherstation in a PVsyst simulation to compare with the Meteonorm synthetic data used when we initially tendered for the project, as well as to correlate our performance ratio reports.

Unfortunately, I  cannot attach the file type we have of the weatherstation data, but it is available in excel or .dat.

Might you advise how we can use this data and import it into PVsyst.

Should you have any questions, please let me know.

 

Best regards,

S. Matolo

Good day Sydwell 

This can be done through importing a Custom file. Click Databases, Custom file, choose your source file, define your site and click New to start the process of converting the source file to a format that is supported by PVsyst. In this new window you have to define variables such as the file's time step, the format of the date and in which column you find what information. By saving and running a conversion of the data, you can then use this new file in your Project simulation.

Kind regards

Hi Linda,

Thank you for the feedback.

Is there a specific format in which the data should be displayed on the spreadsheet?

To clarify, on my above point, should the data on the spreadsheet follow a certain order?

Kindly see the picture attached in which the data is currently sorted on my spreadsheet.

Hi Sydwell,

The idea with the Custom file import is that you will customize the import based on the specific format of your file. Thus in this tool, you will be prompted to define that for instance 4 lines should be skipped to arrive at the data, the date is found in column 1 and has de format YY/MM/DD HH/MM, the GHI is in column 4 and the temperature in 7 etc.
