Hi Waseem,

For hourly position of the sun, there are three output variables to consider.

Output:Variable,*,Site Solar Azimuth Angle,hourly; !- Zone Average [deg]

This relates the angle from the sun's position away from the north axis on a horizontal plane

Output:Variable,*,Site Solar Altitude Angle,hourly; !- Zone Average [deg]

This relates the angle from the sun's position upward from the horizontal plane / horizon

Output:Variable,*,Site Solar Hour Angle,hourly; !- Zone Average [deg]

This gives the apparent solar time for the current time period, expressed in deg (+ before noon, - after noon).

For more details on these outputs, you can reference the Shading Module portion of the Engineering Reference [HERE].(http://bigladdersoftware.com/epx/docs/8-2/engineering-reference/shading-module.html#solar-position)

I hope this helps!
