6 FAQs about [Photovoltaic labels caution photovoltaic system installed]
What are the labeling requirements for photovoltaic (PV) systems?
The National Electrical Code (NEC) Section 690 outlines specific labeling requirements for photovoltaic (PV) systems to ensure safety and compliance. These requirements were updated in 2020. Visibility After Installation: Labels or markings must remain visible after installation, ensuring they can be easily read during maintenance or emergencies.
How do you label a solar PV system?
PV solar labels must include vital information like the rated maximum power point circuit, the maximum system voltage, the short-circuit current, and more. Plus, solar PV systems must have equipment and components clearly labeled, such as the following parts:
Why are photovoltaic labels and placards important?
Another reason photovoltaic (PV) labels and placards are important for safety is they help protect residents and guests of homes and commercial buildings. Of course, residents who aren’t trained electricians or familiar with solar systems should never try to work on their systems themselves.
How do I communicate the labeling requirements to the installer?
Communicating the labeling requirements to the installer must be clear, concise and adhere to the latest National Electrical Code (NEC) and International Fire Code (IFC) requirements for text height, wording and reflectivity (where required).
Why do solar panels need warning labels and placards?
Many practical, safety, and legal reasons exist that govern why every solar system, whether for a residential home or large commercial building, needs warning labels and placards. To start, a solar panel system for a home or building must have warning labels and safety placards by law.
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.
