pvlib.irradiance.beam_component

pvlib.irradiance.beam_component(surface_tilt, surface_azimuth, solar_zenith, solar_azimuth, dni)

Calculates the beam component of the plane of array irradiance.

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. [°]

• dni (numeric) – Direct normal irradiance, see dni. [Wm⁻²]

Returns:

beam (numeric) – Beam component. [Wm⁻²]
