The primary purpose of Article 690 of the NEC is to provide requirements for the installation of photovoltaic (PV) systems. This article addresses many aspects of PV installation, including components, system connections, grounding, and circuit protection. It ensures that PV systems are installed safely and effectively while complying with necessary electrical standards.

While residential electrical systems, energy efficiency, and safety protocols are essential topics within the NEC, they are addressed in different articles or sections. Article 690 specifically focuses on the unique requirements that come with the installation and operation of solar photovoltaic systems, which include considerations for both safety and performance in these renewable energy installations. This focus makes it crucial for installers and professionals in the field to familiarize themselves with its content to ensure compliance and optimize system reliability.
