pvlib.tracking.calc_axis_tilt(slope_azimuth, slope_tilt, axis_azimuth)[source]#

Calculate tracker axis tilt in the global reference frame when on a sloped plane. Axis tilt is the inclination of the tracker rotation axis with respect to horizontal, ranging from 0 degrees (horizontal axis) to 90 degrees (vertical axis).

Parameters:
  • slope_azimuth (float) – direction of normal to slope on horizontal [degrees]

  • slope_tilt (float) – tilt of normal to slope relative to vertical [degrees]

  • axis_azimuth (float) – direction of tracker axes on horizontal [degrees]

Returns:

axis_tilt (float) – tilt of tracker [degrees]

Notes

See [1] for derivation of equations.
