FAQs 6

Will solar power go out if the power goes out?

Probably not. If you have solar and the power goes out, your power will go out, too—unless you have a backup system. This is because U.S. electrical code requires rapid shutdown of a solar system to protect emergency workers and prevent dangerous backfeed current from passing onto distribution lines.

Does a solar system need a rapid shutdown switch?

Rapid shutdown requirements are only applicable to roof-mounted solar systems. If you’re planning on installing a ground-mounted solar system, you won't have to install a rapid shutdown switch. Rapid shutdown is important because if the sun is shining and your solar system is in proper working order, there’s live electricity running through it.

Is it necessary to shut down my solar system?

If you live in a state where the National Electrical Code (NEC) 2014 or newer is enforced, your solar system will need to follow NEC rapid shutdown requirements to pass the final inspection and be connected to the utility and powered on.

Can a photovoltaic system be shut down in a fire?

Where a photovoltaic (PV) system cannot be shut down in a fire situation, this can make fighting fires more complex with the possibility of the risks of shock in particular being extremely severe. Figures have shown that there has been a higher number of incidents involving solar panels & now we need a coherent framework to do it safely.

Do PV installations need a rapid shutdown?

This interpretation was based on the rapid shutdown requirement for PV circuits installed “on or in buildings” and the discrepancy between the NEC’s definition of a building and the definition found in building codes. This left some jurisdictions taking the most conservative approach and requiring rapid shutdown on nearly all PV installations.

How long does it take to shut down a solar panel?

NEC 2014 requires all controlled conductors beyond ten feet of solar panels to be brought down to 30 volts and 240 volt-amperes within ten seconds of initiating the rapid shutdown switch.
