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.
surface_azimuth (numeric) – Panel azimuth from north.
solar_zenith (numeric) – Solar zenith angle.
solar_azimuth (numeric) – Solar azimuth angle.
- Returns:
aoi (numeric) – Angle of incidence in degrees.
