About Regulations for rapid installation of photovoltaic panels
Rapid shutdown marking requirements from 690.56(C) were moved to 690.12(D), including minor changes in the requirements for the marking. Even though module-level options are allowed in the code, a number of factors make it clear that opting to satisfy UL 3741 instead is the way to go in the future.

Building code requirements related to installation, materials, wind resis- tance, and fire classification can help ensure the safe installation and operation of PV systems. AHJs typically require a PV system to pass a permitting and inspection process prior to com-.
There have been changes throughout the entire 2023 NEC that may affect the installation of photovoltaic (PV) systems. However, this article will concentrate on the changes in Article 690, Solar Photovoltaic (PV) Systems, Article 705, Interconnected Power Production Sources, Article 691, Large-Scale Photovoltaic (PV) Electric Supply Stations .
Buildings with rapid shutdown solar photovoltaic systems shall have permanent labels in accordance with Sections CS512.5.1 (IFC 1204.5.1) through CS512.5.3 (IFC 1204.5.3).
The labeling requirements for rapid shutdown-equipped systems were modified within Article 690.56(C). The label verbiage for array-level rapid shutdown was removed since all rooftop PV systems complying with NEC 2020 will now require de-energization at the module-level.
