Which NEC article covers solar PV systems?

• A. 691
• B. 690
• C. 705
• D. 706

Answer: (B)

The main idea is recognizing where the NEC lays out the rules for installing solar photovoltaic systems. There is a specific article that addresses solar PV installations in detail—from the PV array’s DC wiring and conductors to the inverter, overcurrent protection, disconnects, labeling, grounding, and rapid shutdown requirements. This article also covers how the PV system interconnects with the building’s electrical system and with the utility, using equipment that’s listed for PV use. That dedicated PV article is the right choice because it contains all the installation-specific rules you need to know for safety and code compliance. The other options touch on related topics—such as how multiple power sources interconnect or how energy storage is handled—but they do not provide the full set of PV-installation requirements, which is why they aren’t the best fit here.
