SingleAxisTracker.get_aoi(surface_tilt, surface_azimuth, solar_zenith, solar_azimuth)[source]#

Get the angle of incidence on the system.

For a given set of solar zenith and azimuth angles, the surface tilt and azimuth parameters are typically determined by singleaxis(). The singleaxis() method also returns the angle of incidence, so this method is only needed if using a different tracking algorithm.

Parameters

  • surface_tilt (numeric) – Panel tilt from horizontal.

  • surface_azimuth (numeric) – Panel azimuth from north

  • solar_zenith (float or Series.) – Solar zenith angle.

  • solar_azimuth (float or Series.) – Solar azimuth angle.

Returns

aoi (Series) – The angle of incidence in degrees from normal.
