What does Article 690.7 focus on regarding PV systems?

Article 690.7 of the National Electrical Code specifically addresses the electrical connections of photovoltaic (PV) modules and associated equipment. This section lays out the requirements for how these connections must be made to ensure safety and compliance with overall electrical practices. It includes guidelines on terminations, wiring methods, and other critical aspects that contribute to the safe and effective operation of solar power systems. By focusing on these details, Article 690.7 helps to prevent issues such as electrical failures, short circuits, and fire hazards that could arise from improper connections.

The other options do not align with the specific focus of Article 690.7. Ground rod installation, testing efficiencies of PV modules, and the disposal of old modules are important aspects of PV systems but fall under different parts of the NEC or other regulations rather than Article 690.7. This clarity is essential in understanding the distinct roles that different articles play in the comprehensive framework provided by the NEC for solar energy systems.
