Junction box semi-finished product, solar module semi-finished product, solar module and method for producing a solar module

Description

[0001] The invention relates to a junction box semi-finished product and a solar module semi-finished product which can be connected to one another to produce the solar module, to a solar module comprising the junction box semi-finished product and the solar module semi-finished product, and to a method for producing the solar module.

[0002] A solar module typically comprises a plate-shaped front element, a plate-shaped rear element, and an encapsulation material arranged between the front element and the rear element. The solar module further comprises a plurality of solar cell strings made of solar cells, usually electrically connected in series, which are arranged between the front element and the rear element and are permanently encapsulated in a weather-resistant manner in an encapsulation volume in the form of a solar module laminate by means of the front element, the rear element, and the encapsulation material surrounding the solar cells. The solar cell strings are typically electrically interconnected within the laminate using electrical conductor elements, particularly in the form of cross connectors.Depending on requirements, the electrical interconnection can be a pure series connection of the solar cell strings or a combination of series and parallel connections. The interconnected solar cell strings have electrical connection elements, of which at least one positive pole connection element and one negative pole connection element are led out of the encapsulation volume through an opening formed in the rear element. Furthermore, a junction box is fixed to the solar module in the area of ​​this opening for the permanently weatherproof, sealed electrical contact of the electrical connection elements led out of the encapsulation volume. The junction box has a housing into which the connection elements are inserted and which can also be filled with a filling material to provide the connection elements with permanent weatherproof protection against moisture and corrosion.The junction box is equipped with a first solar module cable serving as the positive pole cable of the solar module and a second solar module cable serving as the negative pole cable of the solar module. These cables are electrically connected to the positive and negative pole connection elements in the junction box. The electrical energy generated by the solar module can be dissipated via the first and second solar module cables.

[0003] CN 106 788 218 A discloses a solar module comprising two positive pole contact elements and two negative pole contact elements, as well as several junction boxes designed for contacting a solar cell string, each with a positive pole contact element and a negative pole contact element. Three junction boxes are each electrically connected via box cables, and the solar module comprises two solar module cables.

[0004] DE 10 2009 022944 A1 describes a solar panel with a solar module, an input junction box, an output junction box, and electrical conductors extending from the solar module. Two of the electrical conductors are connected to the already attached input junction box, and two of the electrical conductors are connected to the already attached output junction box. Six additional electrical conductors protrude from the solar module and are yet to be connected via bridging boxes. The input junction box is bonded to the solar module by means of an input junction box fastening element, and an input junction box cover can be bonded to the solar module. The input junction box fastening element comprises electrical and / or electronic components.

[0005] There is constant economic pressure to reduce the manufacturing costs of solar modules.

[0006] It is an object of the invention to provide a solar module which can be produced in an alternative manner in a simpler and more cost-effective manner.

[0007] The object is achieved by a junction box semi-finished product having the features of patent claim 1, a solar module semi-finished product having the features of patent claim 6, a solar module having the features of patent claim 9, and a method having the features of patent claim 11. Advantageous developments and modifications are specified in the subclaims.

[0008] The junction box semi-finished product and the solar module semi-finished product can be prefabricated in a simple manner. A ready-to-use solar module is obtained by mounting the junction box semi-finished product according to the invention on the solar module semi-finished product according to the invention. In this case, the junction box sub-housing of the junction box semi-finished product and the corresponding housing bases of the solar module semi-finished product are permanently and weather-resistantly connected to form at least two junction boxes. The solar cell strings assigned to the two junction boxes inside the solar module laminate are electrically interconnected by means of a box cable running outside the solar module laminate between the housings. Unlike in the prior art, the interconnection of the solar cell strings takes place entirely or partially outside the solar module laminate. This solution eliminates the need for electrical conductor elements arranged in the solar module laminate for the electrical interconnection of the solar cell strings.The arrangement of these electrical conductor elements before lamination often has to be done manually. Furthermore, during lamination, care must be taken to ensure that the desired spatial arrangement of the solar cell strings and their cross-connectors is maintained. By relocating the cross-connectors outside the solar module laminate, the solar module formed in this way from the junction box semi-finished product and the solar module semi-finished product is significantly simplified and thus more cost-effective to manufacture.

[0009] The invention relates to a junction box semi-finished product for a solar module, comprising a first junction box sub-housing having a first contact device with a first positive pole contact element and with a first negative pole contact element, arranged and designed for electrically contacting one or more positive pole connection elements and one or more negative pole connection elements of solar cell strings of a solar module laminate, at least one further junction box sub-housing having a further contact device with a further positive pole contact element and a further negative pole contact element, arranged and designed for electrically contacting one or more positive pole connection elements and one or more negative pole connection elements of solar cell strings of a solar module laminate, wherein the first junction box sub-housing and the at least one or more further junction box sub-housings are structurally separate from one another, at least one socket cable,which establishes an electrical connection between the first contact device of the first junction box sub-housing and the further contact device of the further junction box sub-housing, a first solar module cable which is connected to the first contact device or to the or one of the further contact devices in such a way that the first solar module cable forms a positive pole connection which is electrically connected via the at least one socket cable to the first contact device and the further contact device or the further contact devices, and a second solar module cable which is connected to the first contact device or to the or one of the further contact devices in such a way that the second solar module cable forms a negative pole connection which is electrically connected via the at least one socket cable to the first contact device and the further contact device or the further contact devices.

[0010] The junction box semi-finished product with its at least two junction box sub-housings, when connected to the solar module semi-finished product, provides simple interconnection of the solar cell strings of the solar module semi-finished product. The junction box semi-finished product can be easily prefabricated before assembly on the solar module semi-finished product. This production can take place in a separate production facility, for example, by a supplier. The at least two junction box sub-housings represent two structurally separate sub-housings of two different junction boxes, but are electrically interconnected via the box cable. This design eliminates the need for the integration and lamination of electrical conductor elements such as cross connectors for electrically interconnecting the solar cell strings inside the solar module laminate of the solar module semi-finished product.

[0011] Preferably, both the first solar module cable and the second solar module cable are connected to the first contact device, while the at least one further contact device is not connected to any solar module cable, i.e. the at least one further contact device is designed without a solar module cable. The first junction box sub-housing, when mounted on a solar module semi-finished product, is part of a main junction box of the solar module thus formed. Solar module cables in the form of a negative pole cable of the solar module and a positive pole cable of the solar module lead from this main junction box, which allow the solar module to be connected to further solar modules. The at least one further junction box sub-housing then becomes part of a satellite junction box, which, when the solar module is in operation, can conduct the electrical current generated by the solar cell strings assigned to it via the box cable to the main junction box.

[0012] The first or further contact device(s) each comprise a first or further positive pole contact element and a first or further negative pole contact element. In a minimal variant, the respective contact device can consist exclusively of the respective positive pole contact element and the respective negative pole contact element. Alternatively, the respective contact device can comprise, in addition to the respective positive pole contact element and the respective negative pole contact element, further structural and functional components, such as an electrical contact strip and electronic components.

[0013] Preferably, the electrical interconnections described above are each a series connection. Preferably, the at least one socket cable establishes a series connection between the first contact device of the first junction box sub-housing and the at least one further contact device of the at least one further junction box sub-housing. However, other variants are also possible and can be implemented more easily via the external electrical interconnection of the solar cell strings using the junction box semi-finished product.

[0014] Preferably, the first and / or the at least one further junction box sub-housing further contain one or more electrical and / or electronic components. This allows the electrical and / or electronic components to be easily replaced if necessary when the junction box semi-finished product is combined with a solar module semi-finished product to form a solar module. Preferably, the electrical and / or electronic components are arranged in a replaceable manner in the first and / or at least one further junction box sub-housing. This means that in the event of a defect, only the defective component does not have to be replaced, not the affected junction box sub-housing.Preferably, the electrical and / or electronic components are all arranged in the first junction box sub-housing, which is part of the main junction box when integrated into the solar module, while the further junction box sub-housing(s) are free of electrical and / or electronic components with the exception of the mandatory positive pole and negative pole contact elements.

[0015] In a preferred embodiment, the first junction box sub-housing contains at least one bypass diode for one or more solar cell strings of a solar module laminate. Alternatively or additionally, the at least one further junction box sub-housing preferably contains at least one bypass diode for a solar cell string of a solar module. If current no longer flows in one or more solar cell strings during operation of the solar module, for example due to contamination or shading, the bypass diode can prevent overheating and defects. In a preferred embodiment, the first junction box sub-housing contains at least one bypass diode for at least one solar cell string of a solar module laminate, and the first contact device is electrically connected to the first solar module cable and the second solar module cable.The at least one further junction box sub-housing is bypass diode-free and the at least one further contact device is not connected to the first solar module cable and the second solar module cable, ie it is designed to be solar module cable-free.

[0016] Preferably, the first junction box sub-housing comprises control and / or analysis electronics for a solar module. Alternatively or additionally, the at least one further junction box sub-housing preferably comprises control and / or analysis electronics for a solar module. More preferably, the first junction box sub-housing is configured with control and / or analysis electronics for a solar module, while the at least one further junction box sub-housing is free of control and / or analysis electronics.

[0017] In a preferred embodiment, the first junction box sub-housing is formed in one piece. Alternatively or additionally, the at least one further junction box sub-housing is preferably formed in one piece. More preferably, the first junction box sub-housing and the at least one further junction box sub-housing are each formed in one piece. This further simplifies the assembly for producing the solar module.

[0018] In a preferred embodiment, the first junction box sub-housing and / or the at least one further junction box sub-housing are each trough-shaped. This provides sufficient space for electrical and / or electronic components that can be integrated into it or them.

[0019] Preferably, the first junction box sub-housing and the at least one further junction box sub-housing have socket locking elements configured to engage with corresponding locking elements of a first housing base or a further housing base of a semi-finished solar module. This allows the solar module to be easily manufactured using a simple yet secure connection method.

[0020] Furthermore, the invention relates to a solar module semi-finished product comprising a plate-shaped front element and a plate-shaped rear element, wherein the rear element has at least two openings, an encapsulation material arranged between the front element and the rear element, a plurality of solar cell strings made of electrically interconnected solar cells, which are arranged between the front element and the rear element and are weather-resistantly encapsulated in an encapsulation volume by means of the front element, the rear element, and the encapsulation material surrounding the solar cells in the form of a solar module laminate, positive terminal connection elements and negative terminal connection elements of the solar cell strings, which are led out of the encapsulation volume through one of the at least two openings as a connection pair for each solar cell string in the form of a positive terminal connection element and an associated negative terminal connection element,wherein the connection pairs are each led out through the spatially closest of the at least two openings and there is no electrical contact between the solar cell strings within the laminate, a first housing base fixed over one of the at least two openings on the solar module semi-finished product, designed to produce a permanently weatherproof housing in conjunction with a mounted junction box sub-housing and at least one further housing base fixed over the other of the at least two openings on the solar module semi-finished product, designed to produce a permanently weatherproof housing in conjunction with a mounted further junction box sub-housing.

[0021] Instead of electrical conductor elements, for example in the form of cross-connectors for interconnecting the solar cell strings inside the solar module laminate, the solar cell strings are interconnected by means of the at least two housing bases in conjunction with the junction box semi-finished product, which has at least one box cable for electrically interconnecting the solar cell strings outside the laminate in the desired manner. This eliminates the need to integrate the electrical conductor elements into the solar module semi-finished product for electrically interconnecting the solar cell strings. Preferably, the solar module laminate of the solar module semi-finished product is designed to be cross-connector-free; i.e., it has electrical conductor elements in the form of cross-connectors inside the solar module laminate.Thus, beyond the electrical conductor elements used to form the solar cell strings themselves, no further electrical conductor elements are required to interconnect the solar cell strings within the solar module laminate. This makes it easier and more cost-effective to manufacture than conventional solar modules and semi-finished solar modules.

[0022] In a preferred embodiment, the openings in the rear side element of the semi-finished solar module are positioned such that they lie over a starting section and an end section of at least one solar cell string. This allows the pair of terminals to be easily led out of the solar module laminate through the opening in a comparatively short path.

[0023] Preferably, the first housing base and the at least one further housing base have further locking elements designed to engage with the first junction box sub-housing or the further junction box sub-housing of the junction box semi-finished product. This allows a permanently weather-resistant junction box to be easily produced.

[0024] Preferably, the first and at least one further housing base are fixed to the rear side element, for example, glued thereto. This allows them to be applied to the rear side element in a simple and automated manner during production of the solar module semi-finished product. The first and at least one further housing base are preferably plate-shaped. The first and at least one further housing base are free of electrical and / or electronic components, apart from the fact that the electrical connection pair of the associated solar cell strings is passed through them. Preferably, the first housing base and the at least one further housing base each have at least one hole through which the connection element(s) of the solar cell strings can be passed.

[0025] Furthermore, the invention relates to a solar module comprising the solar module semi-finished product according to one or more of the embodiments described above and the junction box semi-finished product placed on the first housing base and on the further housing base according to one or more of the embodiments described above.

[0026] In addition to the ease of manufacture of the solar module, one advantage is that the junction box semi-finished product and its electrical components can be easily replaced if necessary, for example in the event of a defect.

[0027] In a preferred embodiment, the first junction box sub-housing is arranged and fixed on the first housing base and the further junction box sub-housing is arranged and fixed on the further housing base in such a way that they form a first junction box or a further junction box, each of which is permanently sealed in a weatherproof manner.

[0028] The first junction box sub-housing and the first housing base form the first junction box, and the at least one further junction box sub-housing and the at least one further housing base form the at least one further junction box. The first junction box is preferably the main junction box and the at least one further junction box is preferably a satellite junction box. In the sense of the invention, a main junction box is a junction box that is electrically connected to the first solar module cable and the second solar module cable, whereas a satellite junction box is a junction box that is not electrically connected to a solar module cable, i.e. it is designed without a solar module cable. Since the satellite junction box is connected to the main junction box via at least one junction box cable, it is able to conduct current into the main junction box during operation.The solar module preferably has a main junction box and two satellite junction boxes.

[0029] Preferably, the positive and negative terminal connection elements of the solar cell strings and the positive and negative terminal connection elements of the junction box semi-finished product are designed to complement each other in such a way that they form an electrical contact when the junction box semi-finished product is placed on the solar module semi-finished product. For example, they are electrically connected by means of a plug connection. Preferably, the positive and negative terminal connection elements of the junction box semi-finished product are designed as female receptacle elements, and the positive and negative terminal connection elements of the solar cell strings are designed as male plug elements.

[0030] The solar module semi-finished product and the solar module are preferably designed as a wafer solar module semi-finished product or as a wafer solar module. A wafer solar module differs from a thin-film solar module in particular in that it comprises wafer-based solar cells rather than thin-film solar cells. Wafer-based solar cells have a thickness greater than 100 µm or, for example, in the range of 180 to 300 µm, while thin-film solar cells have a thickness in the range of a few µm. The solar cells can be half, third, quarter, fifth, or full cells.
