Text-based file format

All PVsyst objects will be written in human-readable text files

Example for a shading scene

PVsyst 6.40

Example for a PV module (PAN file)

Better interoperability between different PVsyst Versions Files can be inspected by users Opens future possibilities to interface with other applications

3D Editor and Shadings Calculation

3D editor Based on OpenGL (V6.41)

Background images in 3D editor

Example1: Screenshot from Google Maps Example2: Technical drawing

Tools allow quick scaling, rotating and positioning of image

PVsyst 6.40
