6 FAQs about [What is the photovoltaic bracket label ]
Do I need a label for a solar PV system?
Solar PV labeling has been simplified for the 2017 code version. Here are the labels required by the NEC and/or NFPA 1 for the typical solar installation. NEC 690.13 (B) label is required at each PV system disconnecting means. This will include combiner boxes, AC/DC switches & AC Disconnects.
Why are labeling requirements important for PV systems?
Before we get into the labeling requirements for PV systems, it’s worth noting why these labels are important for installers and owners of PV systems. There’s always the danger of short circuits, arc flashes, and fires to installers and anyone nearby if they’re not careful.
Do PV systems need labels and warning signs?
Installers should consult the National Electricians Code (NEC) regarding PV systems and any local regulations from cities and municipalities. The basic parts of a PV system that need labels and warning signs include the following: Now that we know what needs labeling, we’ll explore the PV labeling requirements that installers need to know.
How do I choose a label for a solar system?

Consult the NEC to learn how big these labels and placards must be to comply. Get Solar Labels is the place to go if you need labels for a PV system.
Why do I need a voltage label?
This is required for safety purposes to clearly indicate the maximum voltage to servicing personnel for PPE and tool selection. Since some PV equipment, such as certain inverters, may have multiple DC circuit inputs, the highest value present in the system shall be used on the single label.
Do PV systems need a CE mark?
All equipment and/or components of the PV systems must carry a valid CE mark as required by the specific EU directive(s). All labels must be affixed in a suitable, visible location and shall be of a suitable durability for the environment in which they are installed. (Sample labels included in Annex).
