How can I import a quarter-hourly meteo file into PVsyst?

[Nihal Meena]

For loading the 1-minute data into PVSyst Version 8, a specific .MEF file format is needed. Can you help me in doing this because I am getting the different errors? Please do not recommend the help page i already go through the page.
Can you also gave me the email so that I can share the CSV file with you?

Hi,

Indeed the custom import process can be a bit tricky. In the upcoming release of version 8.1, we will introduce a new assistant to help guide users more easily through the construction of the .MEF file.

When importing sub-hourly data, please ensure that the time step is correctly set to 1 minute rather than the default 60 minutes.

The warning message you received indicates that the imported irradiance values are very low compared to the site’s clear-sky model. Is the site correctly defined? If you are importing measured data, it may also be worth checking whether the solarimeter requires calibration or whether the units have been properly specified.

Feel free to send us your site and CSV file at support@pvsyst.com so we can take a closer look.

Kind regards,
