The Solar Flux Calculator macro allows you to calculate the solar flux onto your model based on its orientation, its geographical position, and the time and date.
From the Macros menu, select Modeling > Solar Flux Calculator.
Under Surface Specification, select one of the following options:
Horizontal surface: Select to specify that the model will be flat on a horizontal surface.
Vertical surface tilt: Select to specify that the model will be at an incline and specify the angle.
If you selected Vertical surface tilt, under Face direction specified by, select one of the following options:
Compass: Select to specify that the model is facing one of the cardinal directions.
Relative to South: Select and specify the degrees relative to the South direction the model is facing.
Specify the Time.
Specify the Date.
Specify the Local Latitude.
Specify the Local Longitude.
