6 FAQs about [Photovoltaic panel junction box assembly method]

What is a PV junction box?

A photovoltaic (PV) junction box is an important part of the solar panels. The junction box is an enclosure on the module where the PV strings are electrically connected. The majority of junction box manufacturers are nowadays based in China. How is the junction box connected to the solar panel?

How to attach a junction box to a PV panel?

and the area is about 4300mm2/singer Box. To attach the junction box to the PV panel, thread the PV ribbon through the openings in the bottom of the junction box. Make sure the junction box is properly oriented in a horizontal position before firmly placing the junction box into its final position on the PV panel.

What is a solar panel junction box?

A PV junction box is attached to the back of the solar panel (TPT) with silicon adhesive. It wires the (usually) 4 connectors together and is the output interface of the solar panel. How to connect the solar panel junction box to the solar array? With the use of a junction box, it becomes easy to connect the solar panel to array.

Can a PV junction box be used with multiple rated currents?

If the PV junction box is intended to be used with several types and/or combinations of bypass diode and/ or with several rated currents of the PV junction box, the tests must be performed in all possible combinations with the relevant number of specimens. Another consideration is whether or not the PV junction box is potted.

How to test a PV junction box?

To check if the PV junction box is suitable to be mounted or operated at lower temperatures, a cold impact test has to be performed. After storing the PV junction box for a minimum of 5 hours in a test chamber having a temperature of –40°C, four impacts, each having an energy of 1J, will be administered to the box in different positions.

How LONGi Solar module junction box works?

LONGi solar module junction box contains bypass diode which is in parallel connection with the cell string. If hot spot occurred, the diode will come into operation to stop the main current from flowing through the hot spot cells in order to prevent module over-heated and performance loss.
