On the Circuit Diagram page, you can see a representation of your PV system with standardized circuit symbols. If you are making a 3D planning, you will get the dimensioning plans of the PV areas here as well.
-> How to proceed:
Options
Circuit diagram display: A drawing space in accordance with DIN EN 62446 is stretched over the circuit diagram with the 
With drawing space option. Some contents are already filled out from the project data.
Display circuit diagram: Using the With Legend option, you can display the circuit symbol key and more extensive product information.
Dimensioning plan display: Show the dimensioning plan with the With dimensioning option.
Output
Export 
the circuit diagram in dxf format (Drawing Interchange Format*) for further processing in CAD programs, or in bmp format.
Select a standard paper format (DIN A4, A3, A2, A1, A0) for the export to 
.pdf.
Print the circuit diagram together with the project documentation on the Presentation > 
Display page.
*DXF format is specified by the company Autodesk and is under continual re-development. More detailed information and a free DXF viewer are available at http://www.autodesk.com.
The DXF is exported as an AutoCAD Release 11/12 file.
The majority of other CAD programs from other manufacturers will require the processing of the DXF.
