Edge effect

[Barbadori]

Hi there,

I know that unlimited shed simulation doesn't take into account shed edges but I don't really understand what that really means. What's exactly the edge effect?

Because Near shading simulations takes into account this effect, I take it that it's more accurate to use the near shading vs unlimited shed, is that correct?

Many thanks in advance for the response.

Yes, it is correct that a 3D shade scene is more representative. The edge refers to the the modules which are along the edges of the array. If you have a square block, it is the first row, top row, left side, and right side. These modules receive less shading, more reflected irradiance, etc, and hence more energy.
