systemdef
(meta, surface_tilt, surface_azimuth, albedo, modules_per_string, strings_per_inverter)[source]¶ 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’
