technical field [0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a high-current-carrying modular photovoltaic module bypass element with excellent heat dissipation performance, especially suitable for high-power photovoltaic modules, 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 o...
