Hi, I am trying to simulate the PV-performance using the Equivalent one diode model. Doing the simulation the error occurs : invalid pv performance object name. When I am doing the same simulation with the same name using the simple model everything goes well. Has someone a suggestion?

The simple PV model looks like this:

@Leo please add the tag for the simulation tool that you are using so that others can answer your question better.

@Leo Please post the PV performance object listing in both models so we can take a look at it.

You have added the one-diode PV performance objects, but the PV generator objects are still referencing the original simple PV performance objects. You need to update the Photovoltaic Performance Object Type input field of the Generator:Photovoltaic objects to reference the new PhotovoltaicPerformance:EquivalentOne-Diode objects that you are using to model photovoltaic performance. If you use the text below, it should work.

Generator:Photovoltaic,
  PV0,                     !- Name
  PV0,                     !- Surface Name
  PhotovoltaicPerformance:EquivalentOne-Diode,  !- Photovoltaic Performance Object Type
  PV0,                     !- Module Performance Name
  IntegratedSurfaceOutsideFace,  !- Heat Transfer Integration Mode
  1,                       !- Number of Series Strings in Parallel {dimensionless}
  1;                       !- Number of Modules in Series {dimensionless}

Generator:Photovoltaic,
  PV80,                    !- Name
  PV80,                    !- Surface Name
  PhotovoltaicPerformance:EquivalentOne-Diode,  !- Photovoltaic Performance Object Type
  PV80,                    !- Module Performance Name
  IntegratedSurfaceOutsideFace,  !- Heat Transfer Integration Mode
  1,                       !- Number of Series Strings in Parallel {dimensionless}
  1;                       !- Number of Modules in Series {dimensionless}
