pvlib.tracking.calc_axis_tilt#
- 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
- Returns
axis_tilt (float) – tilt of tracker [degrees]
Notes
See 1 for derivation of equations.
