Compatibility issue with latest Pandas version in gsee.pv.run_model

[phumthep]

Description:

When using gsee.pv.run_model with the newest version of Pandas, I encountered the following issues that require fixes:

1. trigon.py, line 104: The indexing mechanism needs to be updated to handle the latest Pandas changes.

• Current: rise_set_times.loc[item.date()]
• Proposed: rise_set_times.loc[str(item.date())]
• Reasoning: It seems the .date() method now returns a datetime object that is not directly compatible with Pandas indexing, requiring a conversion to a string representation.

2. pv.py, line 243: The clip method usage needs to be adjusted.

• Current: clip_upper(capacity)
• Proposed: clip(upper=capacity)
• Reasoning: The clip_upper method appears to be deprecated in newer Pandas versions. The clip method with the upper argument provides the same functionality.
• These modifications ensure compatibility with the latest Pandas version and prevent errors when using gsee.pv.run_model.

Additional Information:

• The function gsee.pv.run_model has working after the proposed changes
• Pandas version: 2.1.1
• gsee version: 0.3.1
• Python version: 3.10.13
