Inquiry on Simulating PV Façade Installations in PVsyst

[Sara]

 

 

I would like to inquire about the correct procedure for simulating PV façade installations in PVsyst. I have specified the available façade area and set the tilt angle to 90°, but I am uncertain how the software interprets this configuration. Does PVsyst arrange the panels vertically on a single flat surface (side by side), or are they positioned one behind another?

Additionally, is there an alternative or more accurate method to simulate façade-mounted PV systems in PVsyst?

Hello,

The available area in the Pre-sizing help in the System window, serves as a guide for a first order of magnitude of how many panels you can fit on a dedicated surface. This tool take only the size of the panels into consideration (not the spacing between the panels or a pitch). 

If no 3D scene is defined, no configuration other than what is defined in the system and orientation window is considered (no shadings). Defining a 3D scene with the surrounding shading elements, include electrical shading definition etc. will more accurately simulate the system. You find a tutorial for the 3D tool in the following link:

Another potential important parameter for a vertical system would be the reflection on the ground. For a monofacial system, this is discussed in the following forum page:
