SingleAxisTracker.get_irradiance(surface_tilt, surface_azimuth, solar_zenith, solar_azimuth, dni, ghi, dhi, albedo=None, 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().

  • 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

  • albedo (None, float or Series, default None) – Ground surface albedo. [unitless]

  • 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.get_total_irradiance().
