Abstract

The invention discloses a split junction box for a solar cell module. The split junction box comprises a main junction box and an auxiliary junction box, wherein a conductor is arranged in the auxiliary junction box, and the conductor is connected with a bus bar on the solar cell module; the bypass diode and a conducting strip are arranged in the main junction box, and the conducting strip in themain junction box is electrically connected with the conductor in the auxiliary junction box. The invention also discloses a solar cell module comprising the split junction box. The invention can achieve the purposes that the quality of the solar cell module can not be influenced when a circuit part in the junction box has serious problems and the circuit part having the problems is easy to repair.

Description

technical field [0001] The invention relates to a junction box for a solar cell assembly, in particular to a split structure junction box for a solar cell assembly and a solar cell assembly including the junction box. Background technique [0002] Existing junction boxes for solar cell modules are directly installed on the back of the solar cell module. The junction box includes a box body and a box cover, and the box body is provided with a bypass diode, a conductive sheet and a cable+connection head. The conductive sheet is connected to the bus bar of the solar cell assembly, and is used to lead out the current of each cell string. The bypass diodes are connected to the conductive sheets for protecting each battery string. The cable+connector is connected to the conductive sheet for outputting the current in the solar cell module. [0003] In the process of realizing the present invention, the inventor found at least the following problems in the prior art: since the ju...
