6 FAQs about [Photovoltaic panel unpacking self-inspection form]

How do you know if a photovoltaic module is bad?

Where cells have become shiny or changed colour locally, cells have a poor or degrading anti-reflective coating which is an indicator of poor module performance. “IEC 61215: Crystalline silicon terrestrial photovoltaic (PV) modules - Design qualifications and type approval 2nd Edition,” International Electrotechnical Commission, Geneva, 2005.

How do I know if my PV modules have been shipped?

Before you unpack your modules, check the shipping label to ensure you received the right modules. Once you unpack your modules, check the module frame serial number and model label against the shipping label. The serial number is the unique identifier of each PV module.

What happens if a photovoltaic module is exposed to sunlight?

One individual module may generate DC voltages greater than 30 volts when exposed to direct sunlight. Contact with a DC voltage of 30V or more is potentially hazardous. When disconnecting wires connected to a photovoltaic module that is exposed to sunlight, an electric arc may result.

Do roof-mounted PV panels and modules have a fire classification rating?

Rooftop-mounted PV panels and modules have the proper fire classification rating. (CBC 1509.7.2 & CRC R908.1.2)

What happens if you disconnect a photovoltaic module?

Contact with a DC voltage of 30V or more is potentially hazardous. When disconnecting wires connected to a photovoltaic module that is exposed to sunlight, an electric arc may result. Such arcs may cause burns, may start fires and may otherwise create problems. Therefore, be extremely careful!

What are the requirements for a roof-mounted PV system?

Firefighter access according to approved plan. Roof-mounted PV systems have the required fire classification (CBC 1505.9 or CRC R902.4). Grounding/bonding of rack and modules according to the manufacturer’s installation instructions that are approved and listed.
