Yes, it's required by law to add a solar rapid shutdown system to your solar panel system. Importantly, NEC isn't a federal law, so individual states have the option to adopt and comply with the code; hence, the solar rapid shutdown requirements might vary from one state to another.
The regulation codes vary from one state to another, depending on the NEC they've adopted. Microinverters, power optimizers, and string inverters are two types of solar installations. NEC 2014, 2017, and 2020 are the legal requirements for solar rapid shutdown installations. What Is Solar Rapid Shutdown?
Solar rapid shutdown came into existence in 2014 to quickly reduce the voltage flow in conductors during a fire. Your solar panel must have a rapid shutdown switch to abide by the mandate and ensure the safety of first responders during an emergency. The regulation codes vary from one state to another, depending on the NEC they've adopted.
Notably, the controlled conductors located inside the boundary are now required to be limited to 1 foot in length, reinforcing emergency responder's safety during critical situations. NEC 2020 catapulted solar rapid shutdown requirements into a new era.
With the 2023 update, the requirements are stricter than ever. Now, nearly all rooftop PV systems must include rapid shutdown functionality that brings conductors to a safe voltage within seconds of

Without a rapid shutdown device, there is no safe way to turn off the current running through those conductors. Most people would assume that simply turning the solar inverter off would turn the power
