# Tracking¶

## SingleAxisTracker¶

The SingleAxisTracker inherits from PVSystem.

 tracking.SingleAxisTracker(**kwargs) Deprecated since version 0.9.0. Get tracking data. Uses the irradiance.get_total_irradiance() function to calculate the plane of array irradiance components on a tilted surface defined by the input data and self.albedo.

## Functions¶

 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.
