Photovoltaic panel label removal

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.

Which value should be used on a PV label?

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. EXPLANATION: Values for maximum circuit current have been removed from the label requirements since all equipment will be marked with its rated current through its listing.

How do I identify a conductor 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) Always check local codes before defining labeling formats.

How do you label a cable?

Cables can be marked using UL969 approved self-laminating vinyl labels. Circuits relying on other than color-coding for polarity identification shall be identified by an approved permanent marking means such as labeling, sleeving or shrink-tubing that is suitable for the conductor size. Always check local codes before defining labeling formats.

Are there building regulations for solar panels?

There are building regulations for solar panels, as there are for most home improvements. These government regulations are frequently updated to ensure that any alterations made to properties don’t threaten the safety or health of people who live or work in them.
