How is labelled the time step in PVsyst ?

[André Mermoud]

In PVsyst I have taken the convention of always labelling the beginning of a time step (8:00 corresponds 8:00 to 9:00 average).

This allows to label the hours, days or months in the same way.

Now if your own data are referred to the end of the hour (or other time step, you have an option in the importing format for taking this into account).

See My transposed POA values don't match the imported values in this forum.
