# PVAnalytics

PVAnalytics is a python library that supports analytics for PV

systems. It provides functions for quality control, filtering, and

feature labeling and other tools supporting the analysis of PV

system-level data.

PVAnalytics is available at [PyPI](https://pypi.org/project/pvanalytics/)

and can be installed using `pip`:

    pip install pvanalytics

Documentation and example usage is available at 

[pvanalytics.readthedocs.io](https://pvanalytics.readthedocs.io).

## Library Overview

The functions provided by PVAnalytics are organized in modules based

on their anticipated use.  The structure/organization below is likely

to change as use cases are identified and refined and as package

content evolves.  The functions in `quality` and

`features` take a series of data and return a series of booleans.

For more detailed descriptions, see our

[API Reference](https://pvanalytics.readthedocs.io/en/stable/api.html).

* `quality` contains submodules for different kinds of data quality

  checks.

  * `data_shifts` contains quality checks for detecting and 

    isolating data shifts in PV time series data.

  * `irradiance` provides quality checks for irradiance

    measurements. 

  * `weather` has quality checks for weather data (for example tests

    for physically plausible values of temperature, wind speed,

    humidity, etc.)

  * `outliers` contains different functions for identifying outliers

    in the data.

  * `gaps` contains functions for identifying gaps in the data

    (i.e. missing values, stuck values, and interpolation).

  * `time` quality checks related to time (e.g. timestamp spacing)

  * `util` general purpose quality functions.

* `features` contains submodules with different methods for

  identifying and labeling salient features.

  * `clipping` functions for labeling inverter clipping.

  * `clearsky` functions for identifying periods of clear sky

    conditions.

  * `daytime` functions for for identifying periods of day and night.

  * `orientation` functions for labeling data as corresponding to

    a rotating solar tracker or a fixed tilt structure.

  * `shading` functions for identifying shadows.

* `system` identification of PV system characteristics from data

  (e.g. nameplate power, orientation, azimuth)

* `metrics` contains functions for computing PV system-level metrics
