Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and more particularly to a BIPV photovoltaic module with an embedded diode. Background Art

[0002] With the development of renewable energy, BIPV technology has received more and more attention. BIPV photovoltaic modules can not only be used as building materials, but also generate electricity, with the advantages of energy saving, environmental protection, and beautiful appearance. However, there are some problems in the use of current BIPV photovoltaic modules. For example, when some of the cells in the photovoltaic module fail, it will affect the output power of the entire module and may even cause damage to the module. In order to solve this problem, it is usually necessary to install bypass diodes in the photovoltaic module. However, traditional bypass diodes are usually installed on the outside of the photovoltaic module by welding, which not only increases the volume and weight of the module, but also affects the aesthetics and reliability of the module. In addition, the external diode causes the busbars in the module to be arranged and connected in three sections, and the falling of welding debris from the external diode can easily lead to a short circuit.

[0003] Therefore, how to provide a photovoltaic module that can not only reduce the volume and weight of the module but also ensure the overall stable operation is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] In view of this, the present invention provides a BIPV photovoltaic module with an embedded diode, which can not only reduce the volume and weight of the module but also ensure the stability of the overall operation.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions, including: a battery grid, a battery pack, and a connection component; wherein, the battery grid is provided with a plurality of battery packs arranged in a matrix, different battery packs are connected to the main circuit on the battery grid, and a connection component is provided at the connection between the battery pack and the main circuit.

[0006] Preferably, in the above-mentioned BIPV photovoltaic module with an embedded diode, the connecting component includes: a main body, a diode, and a connecting component; wherein, an installation cavity is provided inside the main body, and connecting components are provided at both ends thereof, respectively, and the diode is arranged in the installation cavity, and is electrically connected to the connecting component.

[0007] Preferably, in the above-mentioned BIPV photovoltaic module with embedded diode, a through hole is provided on the connecting component, the main circuit passes through the through hole and is welded to the connecting component, and the through hole of the connecting component is fixed to the battery grid through a connector.

[0008] Preferably, in the above-mentioned BIPV photovoltaic module with embedded diode, the position of the through hole of the connecting component is selected according to actual needs.

[0009] The diode is connected to the main body in an insert-and-embedded manner.

[0010] It can be seen from the above technical solution that compared with the prior art, the present invention discloses a BIPV photovoltaic module with an embedded diode. By adopting a built-in diode design, the number of module wiring boxes is set according to the battery group, and there are only two lead wires and two welding points, which reduces the probability of welding risks. In addition, by opening a through hole on the connecting component, the hole in the glass on the back of the module can be moved outward, and the wiring of the junction box can be further shortened to reduce costs.
