Do solar panels need a DC or AC disconnect?

Local ordinances and building codes require AC and DC disconnects in all solar installations. NEC Article 690.13 requires every PV system in the country to have a solar switch, and many municipalities now mandate rapid shutoff switches, which are essentially DC disconnects attached to or near each individual solar panel.

What is a solar DC disconnect switch?

A solar DC disconnect (or PV disconnect) shuts off the direct current (DC) power traveling from the solar panels to the inverter. DC disconnects are often built into the solar inverter. Do I need a solar disconnect switch? Local ordinances and building codes require AC and DC disconnects in all solar installations.

How to disconnect solar panels?

Turn Off DC and AC Disconnect Switch: As commented in the safety precautions, the first step when disconnecting solar panels is switching off circuit breakers.

Where is the AC disconnect located in a solar PV system?

In a solar PV system the AC Disconnect is usually mounted to the wall between the inverter and utility meter. The AC disconnect may be a breaker on a service panel or it may be a stand-alone switch. The AC disconnect is sized based on the output current of the inverter and will be looked at in depth in a different article.
