Optimization Supply System Part I (decentralized) - IndexError : single positional indexer is out-of-bounds

[AfonsoGoncalves888]

Describe the bug There is an error when trying to run (either in CEA Dashboard and the CEA Console) the Optimization Supply System Part I (decentralized) in CEA 3.33.0

To Reproduce Steps to reproduce the behavior:

1. Lauch a scenario
2. Run Data Management > Demand Forecasting > Energy Potentials (Photovoltaic panels & Solar collectors)
3. Run Optimization Supply System Part I (decentralized)
4. See error
