Which of the following is true regarding PV system components?

The statement that PV system components must be listed or evaluated for application is accurate because the National Electrical Code (NEC) sets specific requirements to ensure safety and reliability. Components such as solar panels, inverters, and mounting systems must meet performance standards and undergo rigorous testing before being used in an installation. This evaluation confirms that they are appropriate for their intended use, capable of handling the electrical demands, and compliant with local regulations.

In general, the NEC emphasizes the importance of using materials and equipment that are certified to ensure they meet necessary safety standards, reducing the risk of fire, electrical shock, or system failure. This makes it crucial for all components, not just a select few, to be properly listed or evaluated to maintain system safety and performance.

In contrast, some options suggest incorrect practices or assumptions. For instance, saying that components can be installed anywhere might neglect the specific requirements for placement and installation safety, while the notion that they are exempt from inspections overlooks the essential role that inspections play in maintaining electrical safety standards. Additionally, stating that only inverters must be evaluated fails to recognize that all parts of a PV system—that is, solar panels, inverters, wiring, and other elements—need to be evaluated to ensure overall system integrity and safety
