Where should the PV system disconnecting means be located?

The PV system disconnecting means must be located in a position that is readily accessible for safety and operational purposes. This ensures that in case of an emergency or for maintenance, personnel can quickly access the disconnecting means to isolate the photovoltaic (PV) system from the electric supply.

Having this disconnect accessible is critical in scenarios where responders or maintenance teams need to quickly de-energize the system. The location should allow for easy identification and access without the need for special tools or permissions.

While options such as remote locations, within the building, and near the main panel may have their uses, they may not guarantee that the disconnect is readily accessible to those who need to operate it safely and efficiently during both routine handling and emergency situations. The NEC emphasizes the importance of minimizing risks and enhancing safety through accessibility, which is why a readily accessible location is the preferred choice.
