6 FAQs about [Photovoltaic panel installation marking and positioning]
What are the PV system marking and labeling requirements?
Here is a quick summary of PV system marking and labeling requirements. Section 690.5 covers the ground fault detection/interruption for the PV system and requires a warning label on the utility-interactive inverter or near the ground-fault indicator at a visible location. Most often, these labels are applied on the inverter by the manufacturer.
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.
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.
Do I need a warning label on my PV inverter?
Section 690.5 covers the ground fault detection/interruption for the PV system and requires a warning label on the utility-interactive inverter or near the ground-fault indicator at a visible location. Most often, these labels are applied on the inverter by the manufacturer. See Figure 1. Figure 2.
What determines the layout of solar panels and anchoring systems?
These four points will condition the layout of the solar panels and the anchoring systems in our solar system: The available surface will determine the general dimensioning. The orientation of the building is critical to knowing the time of exposure. The structural load that it can support to ensure that it can support the panel's weight.
Where can I find a label for a PV inverter?
Section 690.54 requires a label at the point where the PV system interconnects to other sources such as the premises wiring system. The label must have the rated ac output current and the nominal operating ac voltage. This rated ac output current can be found on the inverter nameplate. See Figure 6.
