NEC Article 690 covers the installation and safety requirements for solar photovoltaic (PV) systems. It defines the components like arrays, modules, inverters, and disconnecting means, and outlines how circuits must be sized, protected, grounded, and labelled. Key areas of focus include disconnecting means, conductor sizing, and the proper interconnection with utility services, which often. . Article 690 focuses on reducing the electrical hazards that may arise from installing and operating a solar photovoltaic system, to the point where it can be considered safe for property and people. Whether you're designing a rooftop array or evaluating commercial installations, these numbers hold the keys to energy Nirvana.
