Which of the following statements describes PV modules in terms of labeling when intended for use in PV systems?

Explanation:
PV modules used in PV systems must be listed by a recognized testing laboratory. The listing shows the module has been independently evaluated and meets safety and performance standards for use in solar installations, and it carries a marking (like UL Listed) to prove this. This formal certification is required by the NEC for components in PV systems. Terms like approved, identified, or suitable don’t carry the same official certification status, so listing is the correct and best descriptor.
