Shading objects and reflected beam irradiance on bifacial modules

Recommended Posts

I dont believe that shading objects have an affect on the reflected irradiance which is causing some issues with expectations for bifacial gain. Is there a way to include shading objects to reflected irradiance beams and the bifacial gain? I have simulated with and without and get the same number either way.

@Whitley Forman indeed at the moment the backside irradiance calculation is based on a view factor model (in 2D) that is completely independent from the 3D shading scene, used for the front side. If there are shading objects close to the backside, you can include their effect in the parameter "Structure shading factor".
