PV Modules intended for use in PV systems shall be ___ or be evaluated for the application and have a field label applied.

• A. Listed
• B. Approved
• C. Identified
• D. Suitable

Answer: (A)

Modules used in PV systems must carry a recognized safety certification, either by being Listed or by being evaluated for the specific application and given a field label. Being Listed means the module has undergone testing by a recognized laboratory (like UL, ETL, or CSA) and has been certified to applicable safety standards, with a permanent label indicating this approval. This is the strongest, most widely recognized form of assurance for electrical and fire safety in installations. If a module isn’t Listed, it can still be evaluated for the particular use, but then it must receive a field label showing that the evaluation has been performed for that application. The term Listed is the standard, formal status reflected in the requirement, which is why it best fits the statement. Other terms like Approved, Identified, or Suitable do not carry the same formal certification meaning and wouldn’t satisfy the requirement in the same way.
