 ## What each Directory holds
 
 1. `example/`
+
    * `inverter_example.py`: Makes input data depending on the inverter type and compares it with the type with no data and runs the ML model along with a comparison plot using `plotly`. This is the file that you need to run in order to run the ML model. An example output with Enphase is demonstrated below:

 2. `quartz_solar_forecast`:
+
    * `data.py`: Contains the `make_pv_data()` function, that conditionally checks the inverter type and constructs and `xarray` dataframe
    * `pydantic_models.py`: Contains the PVSite class

      * Once all the processing is done, make sure that your return type is of `pd.DataFrame` that has 2 colums, namely
 
        * `timestamp`: `timestamp=datetime.fromtimestamp(interval_end_time_in_unix_epochs, tz=timezone.utc).strftime('%Y-%m-%d %H:%M:%S')`, and then convert the timestamp column to `pd.to_datetime`
        * `power_kw`: Power in **KiloWatts.** An example is shown below with the formatted `pd.DataFrame`
