6 FAQs about [Can the photovoltaic panel labels be removed ]
Where can I find a safety label for a solar photovoltaic system?
Greentech Renewables packages the most common safety labels, they are available here. This is an introductory article on permit and safety requirements for signage and labeling for solar photovoltaic systems.
What are the labeling requirements for rapid shutdown-equipped PV systems?
The labeling requirements for rapid shutdown-equipped systems were modified within Article 690.56 (C). The label verbiage for array-level rapid shutdown was removed since all rooftop PV systems complying with NEC 2020 will now require de-energization at the module-level.
How do I know if a PV system has a maximum DC voltage?
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: A single field-applied label indicating the maximum DC voltage must be installed for any PV system with DC circuits.
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.
How do you permit a photo voltaic system?
One of the most important steps of the permitting process of a photo voltaic system is the signage and labeling that identifies the existence of electrical components in the vicinity. According to NEC article 690.56, both off-grid and grid-tied systems are required to have permanent plaques or directories.
What changes have been made to label requirements?
Moved several label requirements to relevant sections for clarity. Added the term “Labels” to requirements for “placards and directories.” Consolidated all placard requirements found in 690.56 or 712.10 as example into Article 705.10. Other sections will reference 705.10 unless the placards are mentioned or required for stand-alone systems.
