The NEC690 Building Inspector’s Guide is a set of reference materials developed for Building Inspectors and AHJ Officials as it relates to Article 690, of the National Electrical Code (NEC 2014) for Photovoltaic Warning Labels. The Guide also covers ANSI Z535.4-2011, the standard for the development of Product Safety Signs and Labels, which .
A permanent readily visible label indicating the highest maximum DC voltage in a PV system, calculated in accordance with 690.7, shall be provided by the installer at one of the following locations: (1) DC PV system disconnecting means (2) PV system electronic power conversion equipment (3) Distribution equipment associated with the PV system.
PHOTOVOLTAIC SYSTEM DC DISCONNECT WARNING LABEL WITH SYSTEM SPECIFICATIONS, APPLIED TO ALL PHOTOVOLTAIC DC DISCONNECTS; PER DC DISCONNECT (2 TOTAL). NEC 690.15 & NEC 690.13(B) 596-00255. LABELS ARE TO APPEAR AT EVERY SECTION OF THE WIRING SYSTEM THAT IS SEPARATED BY ENCLOSURES, WALLS, PARTITIONS, CEILINGS OR FLOORS.
The IFC specifies that the markings must be visible from a distance, which means that the minimum text height is 3/8 inch using white lettering on a red background. All other warning and caution labels can have a heading that is at least 1/4 inch tall and body text that is at least 1/16 inch tall.

6 FAQs about [Which label can determine whether a photovoltaic panel is good or not ]
What are the PV labeling requirements?
The labeling requirements for Solar Photovoltaic (PV) systems depend on various factors such as the voltage production, installation location, and commercial or residential use. One of the most common requirements for direct current photovoltaic power sources is labeling with information about:
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.
Why do you need a solar PV label?
Labels and signage can warn workers of these dangers and encourage them to protect themselves. They’re also crucial for maintenance and repairs of the solar PV system after installation. Maintenance and repair workers rely on up-to-date and accurate labels to ensure their safety and help them work efficiently.
How do I choose a label for a solar system?
The labels and signs should be permanent and highly visible with contrasting colors to ensure the residents and maintenance or repair workers can find, read, and understand them. 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.
What are the most common solar panel testing standards & certifications?
Below are some of the most common solar panel testing standards and certifications to look for when comparing solar panels: The IEC is a nonprofit establishing international assessment standards for electronic devices, including photovoltaic (PV) panels.
How do I identify the conductors of a PV system?
Where conductors of more than one PV system occupy the same junction box, raceway or equipment, the conductors of each system shall be identified at all terminations and splice points. Cables can be marked using UL969 approved self-laminating vinyl labels. (Figure 34)
