Which article discusses Solar Photovoltaic (PV) Systems?

Article 690 of the National Electrical Code (NEC) specifically addresses the requirements for Solar Photovoltaic (PV) Systems. This article covers various aspects of PV system installation, including safety provisions, design, and connection to the electrical grid. It establishes guidelines for the wiring methods, equipment ratings, grounding, and bonding of PV systems to ensure safety and efficiency.

The focus on these regulations is vital due to the increasing adoption of solar technology and the unique characteristics of PV systems that differ from conventional electrical installations. Understanding this article is crucial for electricians involved in solar energy projects, as it helps to ensure compliance with safety standards and effective installation practices.

In contrast, other articles such as those pertaining to swimming pools (Article 680), communication circuits (Article 670), and general electrical wiring methods (Article 660) do not specifically deal with the regulations governing solar photovoltaic systems. Therefore, Article 690 is the definitive resource for understanding the requirements and best practices for installing and maintaining PV systems.
