Adding labels to specific faces of a model

The solar panels are a custom component that is placed on the face, so I would imagine there is a way to check that, but I don’t know how to do that …

Let us assume that you have a reference to a solar panel, named sp.

You can find one of these simply enough using the Enumerable library methods that are mixed into SketchUp::Entities class objects (as well as most other API collection classes.)
I posted examples here in the forum:

Selecting Specific Entity, Group or Component (By Name)

See: Sketchup::DefinitionList.[] Because you are asking about filtering and searching, (and the API docs do not actually say so,…) I’ll assume you do not know that most SketchUp API collection classes mix in the Ruby Enumerable library. So say that wasn’t exactly the definition name that you wanted to find, but one of a certain definition’s instances. Using the definition list subscript method, you get the definition reference, then use one of the Enumerable search methods to find the exact …

Now,… if the component was set up as a glue to component, then you can get the face the instance is “snapped” to:

mounting_surface = sp.glued_to()
