What is the square box on the back of the photovoltaic panel [PDF]

6 FAQs about [What is the square box on the back of the photovoltaic 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 solar panel be connected without a junction box?

Without a junction box for solar panels, it is likely impossible to facilitate the safe transfer of electricity from the panel to the inverter or battery system. Therefore, it is not recommended to connect a solar panel directly to a load without a junction box.

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?

Why do solar panels have diodes inside a junction box?

“The diode is the gateway that allows an endless stream of power.” If part of a solar panel is shaded, that string will want to consume power, reversing the flow of electricity. Diodes inside the junction box prevent that from happening. There are two different junction box production techniques—soldering/potting and clamping.

How to install a solar junction box?

When installing the junction box, the glue should be applied evenly and comprehensively to ensure the complete sealing between the box body and the backsheet of the solar panel. Be sure to distinguish the positive and negative poles when installing the junction box.

How to connect a solar panel to an array?

With the use of a junction box, it becomes easy to connect the solar panel to array. Usually cables with MC4 / MC5 connectors at the end are used. A good junction box keeps corrosion at the terminals to a minimum, as it will exclude water coming in. When purchasing solar modules, always have a look at the IP rating of the PV junction box.
