What Is a PV Junction Box?

A PV junction box is an electrical enclosure installed on a photovoltaic module to provide a protected connection between the module’s internal circuit and external PV cables.

A junction box is an important part of a solar panel because it helps protect electrical connections from moisture, dust and other outdoor environmental conditions. Depending on the module design, a PV junction box may also accommodate components such as bypass diodes.

The junction box must be selected according to the module’s electrical ratings, connection method, environmental requirements and applicable certification standards.
