PVsyst 8 - Subhourly new features

[rMotta]

What this new feature means?

How to allow the hourly simulation to use the correction properly?

 

[Michele Oliosi]

If you import sub-hourly data you can then use that as an enhanced MET file in your simulations.

Here is a help page that breaks it down: https://www.pvsyst.com/help/physical-models-used/grid-inverter/subhourly-clipping-correction.html

Are there any plans to include the clipping correction button under the known format method? Certain weather data sources provide sub-hourly data in time-series format in a single file, which is useful to import through the known format menu, since it will generate each year automatically into a separate weather files. Otherwise, we will be required to separate the file into 22 files then import through the custom format each file. The other option would be to allow the custom import feature to import more than one year, automatically generating a new file for each year (and not have the menu pop up each time asking the user to check the file, which should come only at the end of the file).

@dtarin yes there are actually plans to completely rewrite the weather data import, to address these two issues and others in one go.

Hi Michele - adding onto this, is it currently possible to export a subhourly production timeseries if you have imported subhourly data using the methods described above, or is it only for suhourly clipping calcs now?

[Robin Vincent]

No, the simulation itself is still hourly-based. We only extract additional info from sub-hourly weather data to correct the clipping losses.
