tracking.singleaxis(apparent_zenith, ...[, ...])

Determine the rotation angle of a single-axis tracker when given particular solar zenith and azimuth angles.

tracking.calc_axis_tilt(slope_azimuth, ...)

Calculate tracker axis tilt in the global reference frame when on a sloped plane.

tracking.calc_cross_axis_tilt(slope_azimuth, ...)

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.
