How is the PV system size determined?

[Chae Han Lee]

Hello,
I’m trying to manually input the horizon profile, but I’m not sure what exactly "PV system size" refers to.

According to the tutorial, far shading is defined as being at a distance greater than 10 times the PV system size. However, it's unclear what this "system size" means. Is it 10 times the installation footprint? Or the distance from the center of the PV site to its edge?

I couldn't find any official documentation clearly explaining this, so I’d appreciate any clarification.

Please excuse any awkward phrasing—I used a translator.

Hi,

This is an order of magnitude estimate, so we did not feel the need to be too precise. To be on the safe side: you can work with twice the distance from the center of the PV site to the edge.
