pvlib.solarposition.get_solarposition#

pvlib.solarposition.get_solarposition(time, latitude, longitude, altitude=None, pressure=None, method='nrel_numpy', temperature=12.0, **kwargs)[source]#

A convenience wrapper for the solar position calculators.

Parameters:

time (pandas.DatetimeIndex) – Must be localized or UTC will be assumed.
latitude (float) – Latitude in decimal degrees. Positive north of equator, negative to south.
longitude (float) – Longitude in decimal degrees. Positive east of prime meridian, negative to west.
altitude (float, optional) – If not specified, computed from pressure. Assumed to be 0 m if pressure is not supplied.
pressure (float, optional) – If not specified, computed from altitude. Assumed to be 101325 Pa if altitude is not supplied.
method (string, default 'nrel_numpy') –
‘nrel_numpy’ uses an implementation of the NREL SPA algorithm described in [1] (default, recommended): spa_python()

’nrel_numba’ uses an implementation of the NREL SPA algorithm described in [1], but also compiles the code first: spa_python()

’pyephem’ uses the PyEphem package: pyephem()

’ephemeris’ uses the pvlib ephemeris code: ephemeris()

’nrel_c’ uses the NREL SPA C code [3]: spa_c()
temperature (float, default 12) – Degrees C.
kwargs – Other keywords are passed to the solar position function specified by the method argument.
