pvlib.pvsystem.systemdef

pvlib.pvsystem.systemdef(meta, surface_tilt, surface_azimuth, albedo, modules_per_string, strings_per_inverter)

Generates a dict of system parameters used throughout a simulation.

Parameters:

• meta (dict) –

  meta dict either generated from a TMY file using readtmy2 or readtmy3, or a dict containing at least the following fields:

  meta field	format	description
  meta.altitude	Float	site elevation
  meta.latitude	Float	site latitude
  meta.longitude	Float	site longitude
  meta.Name	String	site name
  meta.State	String	state
  meta.TZ	Float	timezone

• surface_tilt (float or Series) – Surface tilt angles in decimal degrees. The tilt angle is defined as degrees from horizontal (e.g. surface facing up = 0, surface facing horizon = 90)
• surface_azimuth (float or Series) – Surface azimuth angles in decimal degrees. The azimuth convention is defined as degrees east of north (North=0, South=180, East=90, West=270).
• albedo (float or Series) – Ground reflectance, typically 0.1-0.4 for surfaces on Earth (land), may increase over snow, ice, etc. May also be known as the reflection coefficient. Must be >=0 and <=1.
• modules_per_string (int) – Number of modules connected in series in a string.
• strings_per_inverter (int) – Number of strings connected in parallel.

Returns:

Result (dict) –

A dict with the following fields.

• ’surface_tilt’
• ’surface_azimuth’
• ’albedo’
• ’modules_per_string’
• ’strings_per_inverter’
• ’latitude’
• ’longitude’
• ’tz’
• ’name’
• ’altitude’
