pvlib.solarposition.pyephem¶

pvlib.solarposition.pyephem(time, latitude, longitude, altitude=0, pressure=101325, temperature=12, horizon='+0:00')[source]¶

Calculate the solar position using the PyEphem package.

Parameters:

time : pandas.DatetimeIndex: Localized or UTC.
latitude : float: positive is north of 0
longitude : float: positive is east of 0
altitude : float, default 0: distance above sea level in meters.
pressure : int or float, optional, default 101325: air pressure in Pascals.
temperature : int or float, optional, default 12: air temperature in degrees C.
horizon : string, optional, default ‘+0:00’: arc degrees:arc minutes from geometrical horizon for sunrise and sunset, e.g., horizon=’+0:00’ to use sun center crossing the geometrical horizon to define sunrise and sunset, horizon=’-0:34’ for when the sun’s upper edge crosses the geometrical horizon

Returns:

pandas.DataFrame: index is the same as input time argument The DataFrame will have the following columns: apparent_elevation, elevation, apparent_azimuth, azimuth, apparent_zenith, zenith.
