NEC Article ___ covers large-scale solar PV facilities.

• A. 691
• B. 706
• C. 690
• D. 705

Answer: (A)

The idea being tested is that very large solar installations have their own NEC guidance separate from smaller systems. Large-scale PV power production facilities are covered by a dedicated NEC article that addresses the unique design, wiring, protection, and interconnection needs of utility-scale solar farms. This article sets requirements tailored to big arrays, longer runs, higher fault levels, and the coordination with the power grid, which differ from what’s required for typical rooftop or small commercial PV setups. The general PV article is written for smaller installations and covers common components and protections appropriate to those systems, including rooftop contexts and similar scale projects. Other NEC articles deal with related topics such as interconnecting to other power sources or including energy storage, which may be part of a large project but do not replace the specific rules for large-scale PV facilities.
