pvlib.tracking.SingleAxisTracker.get_irradiance¶

SingleAxisTracker.get_irradiance(surface_tilt, surface_azimuth, solar_zenith, solar_azimuth, dni, ghi, dhi, dni_extra=None, airmass=None, model='haydavies', **kwargs)[source]¶

Uses the irradiance.get_total_irradiance() function to calculate the plane of array irradiance components on a tilted surface defined by the input data and self.albedo.

For a given set of solar zenith and azimuth angles, the surface tilt and azimuth parameters are typically determined by singleaxis().

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.
dni : float or Series: Direct Normal Irradiance
ghi : float or Series: Global horizontal irradiance
dhi : float or Series: Diffuse horizontal irradiance
dni_extra : float or Series, default None: Extraterrestrial direct normal irradiance
airmass : float or Series, default None: Airmass
model : String, default ‘haydavies’: Irradiance model.
**kwargs: Passed to irradiance.total_irrad().

Returns:

poa_irradiance : DataFrame: Column names are: total, beam, sky, ground.
