bifacial_radiance.RadianceObj

class bifacial_radiance.RadianceObj(name=None, path=None, hpc=False)

The RadianceObj top level class is used to work on radiance objects, keep track of filenames, sky values, PV module configuration, etc.

Parameters:

• name (text to append to output files) –

• filelist (list of Radiance files to create oconv) –

• nowstr (current date/time string) –

• path (working directory with Radiance materials and objects) –

__init__ : initialize the object

_setPath : change the working directory

__init__(name=None, path=None, hpc=False)

initialize RadianceObj with path of Radiance materials and objects, as well as a basename to append to

Parameters:

• name (string, append temporary and output files with this value) –

• path (location of Radiance materials and objects) –

• hpc (Keeps track if User is running simulation on HPC so some file) – reading routines try reading a bit longer and some writing routines (makeModule) that overwrite themselves are inactivated.

Returns:

none

Methods

__init__([name, path, hpc])	initialize RadianceObj with path of Radiance materials and objects, as well as a basename to append to
