Tracking#
| 
 | Determine the rotation angle of a single-axis tracker when given particular solar zenith and azimuth angles. | 
| 
 | Calculate tracker axis tilt in the global reference frame when on a sloped plane. | 
| Calculate the angle, relative to horizontal, of the line formed by the intersection between the slope containing the tracker axes and a plane perpendicular to the tracker axes. | |
| 
 | Calculate the surface tilt and azimuth angles for a given tracker rotation. |
