Description

A crystalline silicon solar cell module with an integrated busbar

technical field

The invention relates to a solar cell assembly, in particular to a crystalline silicon solar cell assembly provided with an integrated bus strip. the

Background technique

At present, conventional solar cell modules are arranged vertically, and every two diodes in the photovoltaic junction box are connected in parallel, so that a single diode protects more cells and is prone to hot spot effect; The photovoltaic junction box is not conducive to the heat dissipation of the components, which will reduce the safety performance of the components, and even easily lead to overheating and burnout, which will affect the use of the components; and the cables for connecting the positive and negative terminals of a junction box need to be long, which is not conducive to Installation and power harvesting. the

Contents of the invention

The technical problem to be solved by the present invention is to provide a crystalline silicon solar cell module with an integrated confluence strip, which adopts the horizontal arrangement of the battery modules and integrates diodes inside, increases the heat dissipation area of the battery module, reduces the heat collection load of the junction box, and reduces the failure of the module probability. the

The technical solution adopted by the present invention to solve the technical problem is: a crystalline silicon solar cell module provided with integrated busbars, including cells, junction boxes and connectors, characterized in that it also includes integrated busbars evenly arranged with diodes; The battery slices are arranged horizontally, the integrated bus strip is arranged on the top of the battery slices, and the diodes are fully connected in series. the

As a further improvement, there are two junction boxes. There are no diodes in the two junction boxes and they are respectively arranged on both sides of the back of the cell. the

The present invention adopts horizontal arrangement of battery slices, such as changing the conventional 6×12 arrangement to 12×6 arrangement, which does not affect the installation and use of the components, and enhances the performance of the components, reducing the battery protection of each diode on the original basis. The number of pieces; the wires are drawn out from two junction boxes; the junction box does not need a diode, which increases the heat dissipation area of the component, and the junction box body can be simpler and more convenient to design; the length of the cable can also be appropriately reduced, while reducing power loss. It is also beneficial for users to install and reduce costs. Moreover, the present invention does not need to use insulating strips, reduces the amount of materials used in the components on the original basis, and simplifies the production process at the same time, which is beneficial to the actual production operation. the

The beneficial effects of the present invention are: the battery slices are arranged horizontally and the diodes are integrated inside the battery assembly by means of integrated busbars, which increases the heat dissipation area of the battery assembly, reduces the heat collection load of the junction box, and reduces the failure probability of the assembly. Two junction boxes reduce cable length and cost. the
