System Capacity: 4.95MW

Panel Type - Trina 450W DE17M(II)

Inverter Type - ABB PVS980-58-5000kVA-L

Number of Panels: 11,000

Number of Inverters: 1

Mounting Type: Single Axes Tracker

Mounting Model: Nextracker NX Horizon

Such a system may easily be defined in PVsyst. You have all the required elements for that.

You can get hourly data by defining a CSV output file (for EXCEL) using "Advanced simul > Output file". Here you can define the simulation variables you want to export.


Hi, I do that but when I chose E_Grid ( in my case) and I push 'OK'. Later I dont know where I can look for the CVS file o how to export it.

After defining the data you want to get in the CSV file, please don't forget to check "Datafile output / Output on filename" top left.

The file will be available at the end of the next simulation. The simulation will notify you where it is located (i.e. in your workspace \Userdata\).

NB: You have to re-check the option "Output on filename" at each executions when you want an output file.

NB2: This is fully explained in the help "Project design > Simulation > Simulation: export ASCII file", available by F1 in the importing tool.

You have access to the Help by F1 (or little questionmark buttons for mor specific information) from everywhere in the software. Please use it.
