PV Error

[curiotrope]

I've been trying to model a dwelling with PV and keep getting an error message.

Here is the code I've been using:

house = Dwelling(
    start_time=dt.datetime(2023, 1, 1, 0, 0),
    time_res=dt.timedelta(minutes=1),
    duration=dt.timedelta(days=365),
    hpxml_file =os.path.join(r'C:\Users\cstone\OneDrive - Advanced Energy\Desktop\Projects\Flexible_Demand\OCHRE\DR_Standards_Comparison_HP35_DR_PVBESS.xml'),
    schedule_input_file=os.path.join(r'C:\Users\cstone\OneDrive - Advanced Energy\Desktop\Projects\Flexible_Demand\OCHRE\schedule.csv'),  
    weather_file=os.path.join(r'C:\Users\cstone\OneDrive - Advanced Energy\Desktop\Projects\Flexible_Demand\OCHRE\USA_NC_Raleigh-Durham.Intl.AP.723060_TMY3.epw'),
    verbosity=9,
    Equipment={
         'PV': {
             'capacity': 5,
             'tilt': 20,
             'azimuth': 180,
         },
    },
)

and here is the error I get:

How do I fix this error?

[mnblonsky]

This is a known issue. It's been fixed in the dev branch. I'd recommend running with that branch. If you need to switch branches and already have ochre installed, I would run:

pip uninstall ochre-nrel
pip install git+https://github.com/NREL/OCHRE@dev

We'll have this fixed in the next release.
