pvlib.irradiance.aoi#
- pvlib.irradiance.aoi(surface_tilt, surface_azimuth, solar_zenith, solar_azimuth)[source]#
Calculates the angle of incidence of the solar vector on a surface. This is the angle between the solar vector and the surface normal.
Input all angles in degrees.
- Parameters:
surface_tilt (numeric) – Panel tilt from horizontal. See surface_tilt. [°]
surface_azimuth (numeric) – Panel azimuth. See surface_azimuth. [°]
solar_zenith (numeric) – Solar zenith angle. See solar_zenith. [°]
solar_azimuth (numeric) – Solar azimuth angle. See solar_azimuth. [°]
- Returns:
aoi (numeric) – Angle of incidence, see aoi. [°]
