The invention provides an improved modular photovoltaic module bypass element. The improved modular photovoltaic module bypass element comprises a first conductive terminal, a bypass protection devicepackaging module and a second conductive terminal; the end, extending into an insulating plastic package body, of the second conductive terminal is provided with a first protruding part and a secondprotruding part; two bypass protection devices are arranged on the first protruding part and the second protruding part respectively, and the area ratio of the first protruding part to the second protruding part is 0.8-1.2. According to the modular photovoltaic module bypass element, a double-diode chip design is adopted, so that the current-carrying capacity and the heat dissipation capacity of the bypass element are enhanced; the areas of the two protruding parts of the conductive terminal provided with two diode chips are designed to be approximately equal or equal, so that the current-carrying capability and the heat dissipation capability can be optimized; and with the modular design adopted, the production of wiring terminals of various structures during the processing of the junction box can be avoided, the investment of additional stamping dies can be saved, the management of parts in a production process is facilitated, the cost is saved, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to an improved modularized photovoltaic module bypass element and a photovoltaic module junction box with the bypass element. Background technique [0002] Solar photovoltaic modules are devices that convert solar energy into electrical energy. In the production process of photovoltaic modules, the junction box plays an important role in the effective output of photovoltaic power. Its main function is to output the current generated by photovoltaic modules and protect solar photovoltaic modules. The current generated by each solar panel is relatively small, and it is necessary to use a photovoltaic junction box to electrically connect multiple solar panels to each other, so that the current generated by multiple solar panels can be aggregated and output to form a photovoltaic system with a certain power generation capacity. [0003] In actual use, the pho...
