Far shading

Is defined as "Far shading" the shadows produced by objects distant from the system, typically this is the horizon line which in some cases can present obstacles (such as mountains) that limit the irradiation time on the system. The loss resulting therefrom can be calculated by defining a diagram representing the horizon line.

The definition of the diagram is done with the command Far shading in Location menu

The calculation of loss due to the far shading assumes that the entire system undergoes simultaneously the shadow presence. But this approximation is admissible only if the diagram of the horizon line does not consider neighboring objects to the system.
