Determine GHI, DNI, DHI from POA global using the GTI DIRINT model.

.. warning::

    Model performance is poor for AOI greater than approximately
    80 degrees `and` plane of array irradiance greater than
    approximately 200 W/m^2.

Parameters
----------
poa_global : array-like
    Plane of array global irradiance in W/m^2.

aoi : array-like
    Angle of incidence of solar rays with respect to the module
    surface normal.

solar_zenith : array-like
    True (not refraction-corrected) solar zenith angles in decimal
    degrees.

solar_azimuth : array-like
    Solar azimuth angles in decimal degrees.

times : DatetimeIndex
    Time indices for the input array-like data.

surface_tilt : numeric
    Surface tilt angles in decimal degrees. Tilt must be >=0 and
    <=180. The tilt angle is defined as degrees from horizontal
    (e.g. surface facing up = 0, surface facing horizon = 90).

surface_azimuth : numeric
    Surface azimuth angles in decimal degrees. surface_azimuth must
    be >=0 and <=360. The Azimuth convention is defined as degrees
    east of north (e.g. North = 0, South=180 East = 90, West = 270).

pressure : numeric, default 101325.0
    The site pressure in Pascal. Pressure may be measured or an
    average pressure may be calculated from site altitude.

use_delta_kt_prime : bool, default True
    If True, indicates that the stability index delta_kt_prime is
    included in the model. The stability index adjusts the estimated
    DNI in response to dynamics in the time series of GHI. It is
    recommended that delta_kt_prime is not used if the time between
    GHI points is 1.5 hours or greater. If use_delta_kt_prime=True,
    input data must be Series.

temp_dew : None, float, or array-like, default None
    Surface dew point temperatures, in degrees C. Values of temp_dew
    may be numeric or NaN. Any single time period point with a
    temp_dew=NaN does not have dew point improvements applied. If
    temp_dew is not provided, then dew point improvements are not
    applied.

albedo : numeric, default 0.25
    Surface albedo

model : String, default 'isotropic'
    Irradiance model.

model_perez : String, default 'allsitescomposite1990'
    Used only if model='perez'. See :py:func:`perez`.

calculate_gt_90 : bool, default True
    Controls if the algorithm evaluates inputs with AOI >= 90 degrees.
    If False, returns nan for AOI >= 90 degrees. Significant speed ups
    can be achieved by setting this parameter to False.

max_iterations : int, default 30
    Maximum number of iterations for the aoi < 90 deg algorithm.

Returns
-------
data : OrderedDict or DataFrame
    Contains the following keys/columns:

        * ``ghi``: the modeled global horizontal irradiance in W/m^2.
        * ``dni``: the modeled direct normal irradiance in W/m^2.
        * ``dhi``: the modeled diffuse horizontal irradiance in
          W/m^2.
