Model option

Zero

No light on the plane in a timestep without sun above the horizon

Inputs used: Diffuse horizontal irradiance, Plane tilt, Albedo

Method

A timestep during which the sun never rises above the horizon receives zero light on the plane, whatever the file holds. Any diffuse value the file carries in such a timestep is dropped.
