Description

Solar module and method for producing a solar module

The invention relates to a solar module and a method for producing a

Solar module.

It is known to integrate solar modules in glass facades. In such a case, solar modules form part of or are attached to the glass elements of such a facade. The use of solar modules in cold and warm facades is known.

Such a facade can in particular also be designed as a curtain wall.

It is known that facade elements of glass facades with so-called point holders, clamps or rail-like or clamp-like one-part or multi-part

Clamps can be attached to a facade. In particular, it is to be ensured here that glass facade elements are protected from a fall in the event of damage or have the lowest possible risk potential.

Previously known solutions attempt to integrate an active layer of a solar module into a so-called glass support layer of such a glass facade element.

DE 101 063 10 A1 discloses a photovoltaic module which is part of a

Photovoltaic system can be used in buildings. The publication further discloses that a rear side of a photovoltaic module can be covered with a laminated safety glass or can be embodied in an insulating glass structure.

A large number of rules and regulations exist for the integration of solar modules in glass facades. For this reason, fastening solutions of this type generally require an individual construction check.

The technical problem arises of creating a solar module and a method for its production which is well suited for use as an element in a glass facade and in particular can be produced in a simple manner in a large number of sizes and shapes and has a high static load capacity.

The solution to the technical problem arises from the objects with the

Features of the independent claims. Further advantageous embodiments of the invention result from the subjects with the features of the subclaims. It is a basic idea of the invention to design a front glass element of a solar module, in particular a solar module of the substrate type, as a laminated safety glass element.

A solar module is proposed. This is used to generate electrical energy from solar radiation. The solar module comprises a front glass element and at least one substrate glass element designed as a rear glass element. Here, a front glass element denotes a glass element of the solar module which faces the sun when the solar module is used as intended, that is to say on the front side. The

Front glass element can have a front flat surface facing the sun when used as intended and a rear flat surface facing the sun when used as intended. In particular, sunlight shines through the front glass element onto an active layer.

The substrate glass element here designates a glass element to which this so-called active layer of the solar module, which is also known as a functional layer, is applied. Here, the rear glass element denotes a

Intended use of the solar module facing away from the sun, i.e. on the back, glass element of the solar module. The rear glass element can likewise have a front flat surface facing the sun when used as directed and a flat surface on the back facing the sun when used as intended. The active layer is here on the

applied to the front surface of the rear glass element.

The type of application of the functional layer can include, for example, vapor deposition or deposition. The substrate glass element thus comprises a glass element and an active layer applied thereon.

According to the invention, the front glass element is designed as a laminated safety glass element (VSG).

In particular, the solar module thus has a substrate structure, the

Front glass element of this solar module of the substrate type as

Laminated safety glass element is formed. The solar module thus differs of a superstrate type in which the active layer is applied to the rear surface of the front glass element.

A connecting means or can be arranged between the front glass element and the rear glass element, in particular between the front glass element and the active layer

Connection element may be arranged. Such a connecting element can

for example made of EVA, PVB or polyolefin or butyl. It is of course possible that such a connecting means or element is formed from different parts, e.g. one part is made of EVA and another part is made of butyl. Such a connecting means or element can be a

Form intermediate element or an intermediate layer between the front and rear glass element.

The laminated safety glass element can in particular two or more

Include glass part elements. Such a glass part element can in particular be a

Single pane safety glass element, a partially tempered glass element or a so-called float glass element. Here, a float glass element denotes

in particular a flat and transparent flat glass element, which is made from a glass melt. Alternatively, the use of plane cast or

Rolled glass possible. This glass composite can in particular have a thickness in a range from 1 mm (inclusive) to 24 mm (inclusive). Intermediate elements or intermediate layers made of organic materials can be arranged between the partial glass elements of the laminated safety glass element, in particular an intermediate layer made of PVB (polyvinyl butyral). The laminated safety glass element can in particular be designed as a laminate.

In other words, a solar module with a rear substrate glass element, which can also be called a functional glass element, and a

Laminated safety glass element designed front glass element proposed. The functional glass element can in particular have a CIGS structure. The structure of the proposed solar module advantageously enables this

Functional glass element is decoupled as completely as possible from loads, in particular static loads, from the laminated safety glass element, since this forms or provides the load-bearing part of the solar module. A load can be a static, dynamic or thermal load. It should be noted here that with a solar module of the substrate type with a

Front glass element, which is not designed as a laminated safety glass, the

Resilience is lower than in the solar module proposed according to the invention, since there is in particular the risk of delamination, in particular on a composite film contained in such a conventional solar module, if the solar module is exposed to loads. The structure according to the invention enables that

Loads can only be absorbed by the front glass element and the functional glass element on the rear thus remains as free as possible from loads. Although the static load on the front glass element increases due to the rear attachment of the functional glass element, laminated safety glass elements are also higher with such an additional static load to accommodate them

Suitable loads. This reduces the risk of delamination, and the proposed solar module can also be used in applications with high static and dynamic loads.

In particular, in contrast to such a conventional solar module structure, it results in a further advantageous manner that sunlight and also the corresponding thermal energy can pass through the laminated safety glass element almost unhindered, thus avoiding the thermal stress within the solar module that delaminates or "creeps" Glass composite, in which the assembled glass elements move slowly under load and / or temperature, could favor.

Furthermore, by moving the functional glass element to the rear of the laminated safety glass element, a cooling effect which is generated by the convection cooling via the air can be used to remove the solar module and in particular that

Cool functional glass element. In this way, the risk of delamination can advantageously be reduced, which in the case of a conventional solar module which is formed as a glass composite from two glass elements and can heat up considerably due to the black surface.

Furthermore, it advantageously results that the functional glass element is held as stable as possible and that it is sufficiently resilient even if the front glass element breaks. Especially in the event that Laminated safety glass element is designed with a partially tempered glass element, these effects can be guaranteed by a missing identical superimposition of a broken glass image between the different glass partial elements of the laminated safety glass element. In other words, there is advantageously a desired high residual load-bearing capacity if the solar module breaks due to the integration of a laminated safety glass.

The structure of the laminated safety glass element determines in particular the

Residual capacity. This can thus be set in a targeted manner in accordance with specifications, in particular by selecting the type and / or the material thickness of the glass and composite materials and / or selecting the storage and size of the

Laminated safety glass element.

In particular, a selection of the

Laminated safety glass element take place, which can be dependent in particular on the type and speed of load entry, the fracture pattern of glass damage and the temperature load. Due to the composite structure and the position of the functional glass on the back, the full residual load-bearing capacity of the laminated safety glass is retained even if the functional glass breaks.

Furthermore, a uniform black surface of a

Glass facade element are provided, which in turn enables an optimal and uniform temperature distribution over the solar module. In particular in the case of a semi-transparent (partially transparent) design, the heat load is distributed more uniformly on the laminated safety glass element from the functional glass element.

Furthermore, simple and varied architectural results result in an advantageous manner

Design options, for example by coloring or printing, in particular using a screen printing process on glass or by printing

Intermediate laminate film or an additional film arranged on the outside as an optical design element or a sputtered color layer of such a solar module.

Furthermore, it advantageously follows that due to the integration of a

Laminated safety glass element, in particular building law approval of the solar module as a glass facade element is simplified. So make one Laminated safety glass element usually a so-called regulated construction product, for which no individual approval for use in a glass facade may be necessary. Since the mechanical properties of the laminated safety glass element are also retained in the solar module according to the invention, the solar module can also be classified as such a regulated construction product. This advantageously avoids having to carry out separate, case-by-case design methods for the mechanical behavior. These properties also advantageously result in a worldwide field of application in

Integration in glass facades.

It is possible that mechanical properties of the glass facade element are determined as a function of a desired installation height

Laminated safety glass, in particular its mechanical properties, is then formed depending on the mechanical properties of the glass facade element. An installation height can be up to 300 m above the ground.

The laminated safety glass can in particular also be manufactured by an external supplier.

The proposed solar module can be used as a facade element in a curtain wall, which can be designed in particular as a framed facade, glued facade, as a facade with a mullion-transom construction or as a MIG facade (rear glass).

The proposed solar module can also be used as a facade element in one

Multi-pane insulating glass facade are used, which can be designed in particular as a framed facade with a window, glued facade or as a facade with a mullion-transom construction.

It is possible that the solar module has more than one, e.g. includes two, substrate glass elements. These multiple substrate glass elements can be arranged on the rear surface of the front glass element or fastened to it. In this case in particular, a dimension, in particular a length and / or a width, can be one

Substrate glass element to be smaller than the corresponding dimension of the front glass element. For example, it is possible that the substrate glass elements attached to the rear surface of the front glass element are attached in different areas of the front glass element. In the case of a front glass element with a rectangular basic shape or with an essentially rectangular basic shape of the rear surface, a substrate glass element can be arranged / fastened in the transverse edge regions and / or in the longitudinal edge regions of the rear surface. Furthermore, the central area, for example the area between the substrate glass elements, can be free of a substrate glass element. In other words, no substrate glass element is arranged in the central area. A transverse edge area can be an area which is arranged on a shorter side of the rectangular basic shape. A longitudinal edge area can be an area on a longer side of the rectangular

Basic shape is arranged. If the basic shape is square, two of the

sides of equal length form transverse sides and the remaining sides orthogonally oriented form longitudinal sides.

Of course, it is also possible that the solar module is exactly one

Substrate glass element comprises, which on the back surface of the

Front glass element is arranged or attached to this. Furthermore, in this case too, a dimension, in particular a length and / or a width, of one

Substrate glass element is smaller than the corresponding dimension of the front glass element. This one substrate glass element can also be arranged in a transverse or longitudinal edge region. This also creates an area of

Front glass element, which is free of a substrate glass element.

Due to the lack of arrangement of a substrate glass element, it is possible to use a

To provide viewing window area through which, for example, a standing or seated human person can see through the solar module, in particular if the solar module is used as a facade element. For this purpose, the areas of the front glass element that are not covered by a substrate glass element can be made transparent. However, it is also possible for regions of the front glass element not covered by a substrate glass element to be non-transparent or only partially transparent, for example semi-transparent or with a desired transmittance. It is further possible that regions of the front glass element which are different from one another and are not covered by a substrate glass element with one another different degrees of transmission are formed. For example, a first uncovered area can be made transparent and a further uncovered area can be made semi-transparent or with a desired transmittance less than one.

Furthermore, a separate interchangeability is advantageous

Glass facade elements possible within a glass facade with several such elements.

The proposed solar module can be used as a glass facade element in a glass facade. It advantageously results here that glass facade elements with an integrated functional glass element can be produced in a large number of sizes and shapes on the basis of such a solar module.

In particular, such a solar module can be used in a so-called warm glass facade, but also in a so-called cold glass facade. The solar module is preferably arranged as a glass facade element in such a way that the solar module can be rear-ventilated, in particular in order to avoid heat build-up and condensation, to remove moisture and to ensure accessibility for an electrical connection.

It can further be provided that the proposed solar module via the

Front glass element and not over the rear glass element on a corresponding

Holding device is stored.

In a further embodiment, the solar module forms a glass facade element. This results in an advantageous manner that a glass facade can be used on the one hand to protect buildings or rooms and on the other hand to generate electrical energy.

It is further possible that at least one holding element for fastening the solar module to a holding device is arranged on the laminated safety glass element. For example, a holding element can be glued to the laminated safety glass element. A point holding element can also be in or via a bore in the

Laminated safety glass element to be attached to this. Such a holding element advantageously enables the complete solar module, which can form a facade element, for example, to be held.

In a further embodiment, the front glass element forms a laminate with the rear glass element. In other words, the front and rear glass elements are connected by lamination. Here, as explained above, in particular

EVA, PVB or polyolefin can be introduced as a connecting intermediate layer between the glass elements, this intermediate layer likewise forming part of the laminate after the lamination. This advantageously results in a mechanically stable connection of the glass elements, which in particular avoids the risk of an unwanted separation of the individual glass elements of the solar module from one another.

In a further embodiment, the front glass element is designed as a step glass element. This can mean that a glass part element of the front glass element is smaller in at least one dimension than a further glass part element thereof

Front glass element is formed. A dimension can be a length, a width, or a thickness.

Preferably, a width and a length of a glass part element on the front when used as intended is greater than the corresponding dimension of the glass part element on the rear side of the front glass element. The front glass element can preferably have a thickness of 1.5 to 8 mm. This results in

advantageously a simplified use of the proposed solar module in so-called cold facades.

However, it is not imperative that the different glass part elements have different dimensions from one another. It is also conceivable that at least one or more, but not all or all of the dimensions of glass part elements of the

Front glass element are the same.

A maximum length of the solar module can correspond to a length of the longest glass part element of the front glass. The maximum length can be in the range from 0 m (exclusively) to 3.2 m (inclusive). A length of the solar module preferably corresponds to a multiple of the length or width of a substrate glass element. A maximum width of the solar module can correspond to a width of the widest glass part element of the front glass element. The maximum width can be in the range from 0 m (exclusively) to 1.2 m (inclusive). The width of the solar module preferably corresponds to a multiple of the length or width of one

Substrate glass element.

The length of a substrate glass element is preferably 1.2 m and the width is preferably 0.8 m. This enables a simple, standardized production of the proposed solar module and advantageously enables good adaptation to common storey heights in residential, administrative and industrial buildings.

Furthermore, solar modules dimensioned in this way can be assembled in a grid-like manner and then electrically connected to form a facade with the desired dimensions.

In a further embodiment, the solar module is designed as an at least two-stage step glass element.

Is the front glass element designed as a step glass element, in particular as

two-stage glass element, the solar module can be designed as a three or multi-stage glass element.

It is conceivable that one, two or three dimensions of the rear glass element are different from the corresponding dimensions of the front glass element or from the corresponding dimensions of the glass partial elements of the front glass element, in particular smaller than these.

In particular, a width and / or a height of the rear glass element can be smaller than a width or a height of at least one glass part element of the front glass element. A width of the rear glass element is preferably smaller than the smallest width of the glass partial elements of the front glass element and / or the height of the rear glass element is smaller than the smallest height of the glass partial elements of the front glass element.

However, it is also possible for one, two or even three dimensions, that is to say a width, height and thickness, of the rear glass element to be the same as the corresponding dimension of the front glass element or of a glass partial element of the front glass element. In particular, it is possible that a width of the rear glass element corresponds to a width of the front glass element or a glass element, in particular on the rear. As an alternative or cumulatively, it is possible that a height of the rear glass element corresponds to a height of the front glass element or a, in particular rear, glass part element and / or a height corresponds to the height of this glass part element.

A dimension can be measured in a reference coordinate system. For example, a thickness of a glass element can be measured along a vertical axis of the reference coordinate system, wherein the vertical axis can be oriented perpendicular to a front surface of the front glass element. A width can be measured along a longitudinal axis of the reference coordinate system and a height can be measured along a transverse axis of the reference coordinate system. The longitudinal and transverse axes can span a plane that is oriented parallel to the front surface of the front glass element. It is also possible that a longitudinal edge of the glass element runs parallel to the longitudinal axis and a transverse edge parallel to the transverse axis.

The design of the solar module as an at least two-stage step glass element advantageously has the result that the solar module enables good usability in a cold glass facade and is stored separately as a facade element in each glass level.

In a further embodiment, the solar module comprises a plurality of rear glass elements, each of which only covers a partial area of a surface, in particular the rear surface, of the front glass element. Alternatively or cumulatively, the active layer is arranged in a plurality of partial areas, each of which only covers a partial area of one, in particular the rear, surface of the substrate glass element. The sub-areas can be spatially separated sub-areas.

A region of the front glass element that is not covered by a rear glass element or by an active layer can be designed to be transparent or semi-transparent. Different areas that are not covered can also differ from one another

Have degrees of transmission. A transmittance can refer to radiation with a wavelength in the visible range. This advantageously results in certain sub-areas of the front glass element remaining free from functional glass elements in the assembled state, which, for example, does not impair the transparency of a glass facade element in the desired areas. In this way, for example, a human person can see through a glass facade element formed by the proposed solar module as freely as possible in desired areas, while the glass facade element can be designed with a functional glass element in other areas through which a person normally does not see through.

This advantageously results in a flexible adaptation of the structure of the solar module to the desired framework conditions, in particular when used as a glass facade element.

In a further embodiment, the solar module comprises at least one further rear glass element, the further rear glass element being spaced apart from the

Substrate glass element is arranged. In particular, the further rear glass element is arranged at a distance from the substrate glass element along the previously explained vertical axis in a direction oriented from the front glass element towards the rear glass element. Such a solar module can form a multi-pane insulating glass element.

It is possible that in this case the solar module comprises at least one spacer element which is arranged between the substrate glass element and the further rear glass element, for example a spacer element made of aluminum or plastic.

This advantageously results in improved use of the

Solar module according to the invention in a warm facade, since the space between the substrate glass element and the further back glass element can serve as an insulating layer. The further rear glass element can in particular be a toughened safety glass (ESG) or a laminated safety glass or a float glass.

Alternatively or cumulatively, the solar module comprises at least one further one

Front glass element, which is spaced from the VSG

Front glass element is arranged. In particular, the further front glass element is along the previously explained vertical axis in one from the rear glass element to the Front glass element oriented direction spaced from the front glass element. Such a solar module can also form a multi-pane insulating glass element

It is further possible that a geometric shape of the front glass element deviates from a geometric shape of the substrate glass element. For example, the front glass element can have an angular, in particular rectangular, basic shape or an angular basic shape with rounded corners or also a round, for example circular or oval, basic shape. It is also conceivable that a basic form of

Front glass element includes both round and square sections.

The substrate glass element can preferably have a rectangular basic shape.

It is also possible that between the front glass element and the

Substrate glass element and / or between the substrate glass element and the further rear glass element and / or between the front glass element and the further

Front glass element is arranged at least one further functional element.

The further functional element preferably does not cover or only partially cover the front glass element, the substrate glass element or the active layer, in other words over part of the surface. But it is also possible that the further functional element

Front glass element, the substrate glass element or the active layer completely covered or covered, in other words over the entire surface.

A functional element can e.g. a screen element, an element for light control or an element for generating light. An element for light control can, for example, be an element for shading the active layer, with a

The degree of shading can be adjustable. A functional element can also be an element for executing multimedia functions, e.g. to reproduce information in a visual and / or acoustic manner.

The further functional element can consist of glass. The further functional element can also be designed like a film, e.g. as a colored film. The

Functional element can, for example, have an adjustable degree of transmission. This can be done, for example, by changing an electrical voltage applied to the functional element is created, set. The further functional element can also be designed as a blind or form such a blind.

It is also possible that between the front glass element and the

Front glass element is arranged at least one further mechanical element.

The further mechanical element preferably covers or covers this

Front glass element, the substrate glass element or the active layer not or only partially, in other words partially. However, it is also possible for the further mechanical element to completely cover or cover the front glass element, the substrate glass element or the active layer, in other words over the entire surface. A mechanical element can serve to mechanically stabilize the solar module. It can be made of a material other than glass. A mechanical element can also be a privacy element or a light control element. The further mechanical element can also be designed in the form of a film or plate, e.g. also colored. The functional element can e.g. have an adjustable transmittance. This can e.g. by changing an electrical voltage that is applied to the functional element. The further mechanical element can also be designed as a blind or can form such a blind.

The further functional element or the further mechanical element can

in particular be embedded in the connecting means explained above.

In a further embodiment, the solar module comprises at least one

Frame element, the frame element being arranged on an edge, in particular a longitudinal edge or transverse edge, of the solar module. It is possible that the frame element is a completely encircling frame element. In this case, the frame element extends along all edges of the solar module.

Alternatively, however, it is also possible for the frame element to extend only along a partial section of a longitudinal or transverse edge of the solar module. In this case, the solar module can also comprise several frame elements. In particular, the frame element or a section, in particular a

stepped section, to be explained below, can be arranged on an edge of the front glass element. The frame element can in particular as a profile or

Agraffenelement be formed. For example, a frame element can be made of stainless steel. If the solar module comprises a plurality of frame elements, for example to form a circumferential frame element, these frame elements can be mechanically connected, in particular welded.

By providing at least one frame element, the solar module can advantageously be mounted in a mechanically safe manner on a holding device, for example a wall or a mullion-transom structure. In particular, the frame element enables the most complete possible load transfer via this

Frame element and thus the best possible relief of the functional glass element. Furthermore, the frame element advantageously prevents glass of the solar module from coming into direct mechanical contact with a support surface of a holding device.

Furthermore, the frame element can be designed such that no section of the frame element is arranged in front of a front surface of the front glass element. Thus, the light irradiation on this front surface is not hindered by the frame element. On the one hand, this minimizes the risk of shading, on the other hand, it advantageously results in a frame that is not visible from the outside, which in turn enables a variable facade design when using the solar module as a glass facade element.

The frame element can be mechanically and / or positively and / or cohesively connected to the solar module, in particular to the front glass element.

Preferably, the frame element with the solar module, in particular the

Front glass element, glued, for example by means of an adhesive layer. Such an adhesive layer can in particular consist of silicone or PU.

The arrangement of the frame element on the edge of the solar module advantageously results in the least possible shading of the solar module by the frame element. In a preferred embodiment, the frame element or a section of the frame element is angled or stepped in cross section. A

The cross-sectional plane can in particular be oriented perpendicular to a central longitudinal axis of the frame element. The central longitudinal axis of the frame element can be oriented parallel to the direction of extension of an edge of the solar module on which the frame element is arranged, in particular thus parallel to the longitudinal axis or transverse axis of the reference coordinate system explained above.

The course of the frame element or of the angled or stepped section can be adapted to a stepping of the solar module, in particular of the front glass element. For example, it is possible for a first step section of the frame element in an edge section of the solar module to cover an end face of a first glass part element of the front glass element. A second stage section of the

Frame element can have a region of a rear surface of the first one that is not covered by a further, in particular rear, glass part element

Cover the glass part. A third step section can then cover an end face of the further glass part element.

It is further possible that a fourth step section of the frame element then covers a partial region of a rear surface of the further glass partial element that is not covered by the rear glass element.

Here, the step sections, in particular the first and the second

Step section, each enclose a right angle. In other words, at least a section of the frame element can have a stepped cross section.

This advantageously results in the most reliable and complete load transfer possible via the frame element of the solar module, in particular via the laminated safety glass element. Thus, the increased can advantageously

Requirements for load-bearing connections in the glass facade area are met.

In a further embodiment, the frame element has at least one

Receiving section for receiving a module holding element section or forms this receiving section. It is possible that the frame element previously explained stepped or angled section and the

Has receiving section or forms. The receiving section and the stepped section of the frame element can different sections of the

Form frame elements. But it is also conceivable that the graded

Section and the receiving section or at least part of these sections are integrally formed.

It is possible for the receiving section to be designed geometrically such that a module holding element section can be arranged in a positive manner in the receiving section in at least one, but preferably in at least two, spatial direction (s).

The receiving section can e.g. be U-shaped in cross section. Here, at least one leg of this U-shaped receiving section can also be part of the

form angled or stepped portion, e.g. one of the step sections explained above, in particular the fourth step section.

This advantageously results in a simplified and reliable mounting of the solar module via a module holding element on a holding device.

It is further possible that the frame element forms a clasp or comprises a clasp section. The bracket can be used to hang the solar module, in particular in a holding device, which can be designed, for example, as a holding rail. It is possible that the holding device is non-positively fastened or can be fastened to a facade.

A module holding element for a solar module according to one of the embodiments disclosed in this disclosure is further proposed. Here, the module holding element has at least one fastening means and / or section for fastening the

Module holding element on or forms a holding device. Such a fastening means or section can, for example, be an opening, in particular a through opening, for receiving a connecting means, for example a screw, a bolt, a threaded bolt, a threaded spindle or some other type of connecting means. Furthermore, the module holding element has at least one holding section for arrangement in a receiving section of a frame element of the solar module or forms this holding section. In particular, this holding section can be designed such that it can be arranged in the receiving section in a form-fitting manner in at least one or in a plurality of spatial directions. The holding section for arrangement in a receiving section can, for example, have a rectangular cross section.

Alternatively or cumulatively, the module holding element has at least one

Receiving section for receiving an edge section of the solar module or forms it. Such a receiving section preferably serves to receive an edge section of the solar module provided with a frame element.

Here, a height of the receiving section for receiving the edge section of the solar module can be greater than a thickness of the solar module or greater than a thickness of the front glass element but less than a thickness of the solar module or greater than a thickness of a front glass part element but less than a thickness of the front glass element, the Height can be measured along the vertical direction explained above, in particular if the edge section is arranged in the receiving section.

It is thus possible for only one end face of the edge section of the

Solar module rests on a bottom surface of the receiving section when the

Edge section is arranged in the receiving section. Other areas of the

The edge section or of the solar module are not in contact with edge surfaces of the solar module.

The receiving section for receiving the edge section of the solar module can in particular be U-shaped in cross section.

A solar module arrangement is further proposed, comprising at least one solar module according to one of the embodiments described in this disclosure and at least one module holding element for fastening the solar module to a holding device according to one of the embodiments described in this disclosure. The solar module, in particular an edge section of the solar module, can be arranged in a receiving section for receiving the edge section of the module holding element. Alternatively or cumulatively, a holding section of the Module holding element in a receiving section of a frame element of the

Be arranged solar module.

This advantageously results in a solar module arrangement that can be easily and reliably attached to a holding device.

In a further embodiment, the solar module arrangement comprises a

Holding device for the at least one solar module. The holding device can in particular be a holding device in a mullion-transom design or a building wall. Of course, other holding devices are also conceivable. This advantageously results in a reliable mounting of the solar module.

In a further embodiment, the holding device is designed as a mullion-transom construction. This was explained above and enables an easily mountable holding device for the solar modules.

In a further embodiment, the solar module is fastened to the holding device by arranging a first edge section in a receiving section of a first module holding element for receiving the edge section, the first module holding element being fastened to the holding device. Next is the solar module, by arranging a holding element section of the first or another

Module holding element in the receiving portion of a frame element of the solar module attached to the holding device. The further module holding element can be different from the first module holding element.

If another module holding element is used, this can also be attached to the

Holding device be attached. It is possible that the frame element and / or the receiving section of the frame element is also arranged on the first edge section of the solar module. However, this is not mandatory. For example, the frame element and / or the receiving section of the frame element can be arranged on an edge section of the solar module which is different from the first edge section of the solar module.

This results in a particularly reliable mounting of the Solar module on a holding device, since this can be fastened to the holding device in two ways, namely on the one hand by receiving the edge section of the solar module and by arranging the holding element section in the receiving section of the frame element.

In a further embodiment, two solar modules are fastened to a common section of the holding device, module holding elements for holding the first solar module being offset along the common section

Module holding elements for holding the further solar module are arranged.

In particular, the solar modules can be fastened on opposite sides of the common section.

This advantageously results in easy accessibility, in particular for dismantling the solar modules from the holding device, and simple access

Disassembly. This in turn enables defective parts to be replaced easily

Solar modules.

A method for producing a solar module is also proposed. A front glass element is provided here. Furthermore, at least one substrate glass element designed as a rear glass element is provided, the substrate glass element comprising a glass element and an active layer applied thereon. The front glass element is also provided as a laminated safety glass element.

Furthermore, the front glass element and the rear glass element are connected, in particular by means of a lamination.

This advantageously results in simple manufacture of a solar module according to one of the previously explained embodiments. So that can

Methods include all of the necessary steps to manufacture a solar module according to one of the embodiments described in this disclosure.

In particular, this results in a production of the solar module, which can advantageously be integrated into existing systems simply and without complex additional adaptations. This in turn enables the production of such a solar module low investment costs and simple implementation of the necessary manufacturing facilities.

Furthermore, there is a quick and simple process of manufacture. In particular, a lamination can take place in a laminator, the functional glass element and the laminated safety glass element in particular being able to be arranged in the laminator in such a way that the functional glass element is arranged on a side facing the hotplate side of the laminator. This advantageously results in the risk of delamination of the laminated safety glass element being reduced during manufacture. This can ensure that the desired resilience of the laminated safety glass element is retained.

As previously explained, the laminated safety glass element forms a so-called regulated construction product. This can be produced by an autoclave process with a PVB film as a thermoplastic. When the

However, the composite security elements do not dissolve the composite. However, it is nevertheless desirable that the laminated safety glass is subjected to as little thermal stress as possible in order not to change its mechanical properties. Thus, the functional glass element is preferably thermally stressed or to a greater extent, in other words fully heated, and on the back on the

Applied substrate glass element, especially as a laminate.

Furthermore, the solar module can be easily manufactured in any size, shape and thickness. Furthermore, the production of the laminated safety glass element and the solar module can be separated in terms of time and space in terms of process and can be carried out in different process steps. This avoids the risk of so-called butyl creep and EVA infiltration.

Back glass element 3 formed substrate glass element 3, which is also referred to below as functional glass element 3. Not shown is an active layer of the functional glass element 3, which on a front surface of the

Functional glass element 3 is arranged.

A reference coordinate system is shown with a vertical axis z and a longitudinal axis x. The vertical axis z is perpendicular to a surface of the

Functional glass element 3 and oriented to surfaces of the first front glass part element 2a and the second front glass part element 2b. Furthermore, the vertical direction z is oriented from the functional glass element 3 to the front glass element 2. A transverse axis y, which is oriented perpendicular to the longitudinal axis x and perpendicular to the vertical axis z, is not shown. The vertical axis z and the longitudinal axis x are also oriented perpendicular to one another. The axes x, y, z form a Cartesian coordinate system. Directional information such as "in front", "front", "" front, "behind", "rear",

“Rear” can refer to the vertical axis z.

A length can denote a dimension along the longitudinal axis x. A width can denote a dimension along the transverse axis y. A thickness or height can denote a dimension along the vertical axis z.

It is shown that the front glass element 2 comprises a first front glass part element 2a and a second front glass part element 2b. It is further shown that the

Front glass element 2 is designed as a step glass element, in particular as a two-step step glass element. This means that a length of the second front glass part element 2b is less than a length of the first front glass part element 2a. Furthermore, a width of the second front glass part element 2b can also be smaller than the width of the first

Front glass part element 2a. Here, the first and the second

Front glass part element 2a, 2b can be fastened to one another in such a way that central central axes of these part elements 2a, 2b are arranged collinearly.

It is shown that a PVB layer 4 is arranged between the first front glass part element 2a and the second front glass part element 2b. This is therefore arranged on a rear surface of the first front glass part element 2a and on a front surface of the second front glass part element 2b.

It is further shown that an intermediate layer 5 between the front glass element 2 and the functional glass element 3 between a rear surface of the second

Front glass part element 2b and the front surface of the functional glass element 3 is arranged. This comprises a butyl sub-layer 5a and an EVA layer 5b.

Here, the butyl layer 5a runs along an outer edge section of the front surface of the functional glass element 3, the EVA layer 5b being arranged in a central section of the front surface of the functional glass element 3.

The front glass element 2 is designed as a laminated safety glass. Furthermore, the front glass element 2 and the functional glass element 3 form a laminate, that is to say they are connected by a lamination. It is also shown that the solar module 1 is designed as a three-stage step glass element. In particular, a width of the functional glass element 3 is smaller than a width of the second front glass partial element 2b and a length of the functional glass element 3 is smaller than a length of the second front glass partial element 2b. A central central axis of the functional glass element 3 is collinear with the central central axes of the

Front glass part elements 2a, 2b arranged.

It is further shown that a thickness of the first front glass part element 2a is greater than a thickness of the second front glass part element 2b. Next is a thickness of the

Functional glass part element 3 smaller than a thickness of the second front glass part element 2b or larger than the thickness of the second front glass part element 2b. The second

Front glass part element 2b can also have the same thickness and size as the first front glass part element 2a.

Fig. 2 shows a schematic side view of a solar module 1, which in the

Essentially like the solar module 1 shown in FIG. 1 is formed. Therefore, reference can be made to the comments on FIG. 1. In contrast to that in FIG. 1

The illustrated embodiment, the front glass element 2 is not designed as a step glass element. As a result, the solar module 1 is designed as a two-stage glass element. In particular, corresponding dimensions, that is to say a length and a width, of the front glass part elements 2a, 2b are the same, but larger than corresponding dimensions of the functional glass element 3.

FIG. 3 shows a schematic side view of the solar module 1 with frame elements 6 shown in FIG. 1. It is shown that a frame element 6 is arranged on a front side of the solar module 1 along a transverse edge than on a front side side of the solar module 1. A silicone or PU layer 7 is arranged between the frame elements 6 and the end face of the corresponding transverse edges and serves to fasten the frame element 6 to the solar module 1. The frame element 6 can have a thickness in the range from 1 mm to 5 mm.

It is shown that a frame element 6 comprises a three-stage section, this three-stage section adjoining an edge course of the transverse edge of the Stepped glass element trained solar module 1 is adapted. In particular, a frame element comprises a first step section 6a, which has an end face

Completely or partially covers the transverse edge section of the first front glass part element 2a. Furthermore, a frame element 6 comprises a second step section 6b, which completely or partially covers a partial area of the rear surface of the first front glass part element 2a, which is not covered by the second front glass part element 2b.

Furthermore, a frame element comprises a third step section 6c, which completely or partially covers an end transverse edge section of the second front glass part element 2b. Furthermore, a frame element 6 comprises a fourth step section 6d, which completely or partially covers a partial area of the rear surface of the second front glass part element 2b, which is not covered by the functional glass part element 3. Furthermore, a frame element 6 comprises a fifth step section 6e, this completely or partially covering an end transverse edge section of the functional glass part element 3. However, the frame element 6 does not comprise a step section for covering part of the rear surface of the functional glass part element 3.

Here, the first step section 6a is at right angles to the second step element 6b and this is at right angles to the third step section 6c and this in turn is at right angles to the fourth step section 6d and this is in turn perpendicular to the fifth step section 6e. In cross section, these sections 6a, ..., 6e are arranged in a step-like manner.

It is further shown that a frame element 6 has, in addition to the three-stage section, a receiving section 8 for a module holding element section 9 (see, for example, FIG. 7). This receiving section 8 is here a U-shaped section of the frame element 6, which is formed by the fourth step section 6d, the fifth step section 6b and a leg section 6f of the frame element. The leg section 6f is in turn arranged at right angles to the fifth step section 6e, but does not form part of the stepped course.

4 shows a schematic side view of two solar modules 1 with

Frame elements 6, which are attached to a wall 15, in particular a building wall, via a module holding element 10 in a first embodiment. This

Module holding element 10 is T-shaped in cross section and has one

Through opening for a fastening screw 11. This can be done through the Module holding element 10, in particular its through opening, are screwed into the wall 15.

When the module holding element 10 is screwed on, the wall and the sections of the T-shaped module holding element 10 arranged at right angles to one another form a receiving section 12 for receiving an edge section of the solar module 1. It is shown here that a transverse edge of the solar module 1, in particular the frame element 6 arranged on this transverse edge, on a bottom side of the

Receiving section 12 rests. The bottom side and a front wall side of the receiving section 12 are formed by the module holding element 10. Another, rear wall side of the receiving section 12 is formed by the wall 15.

It is also shown that a rear surface of a leg section 6f of the frame element 6 bears against the wall 15. A height of the receiving section 12 is greater than a total thickness of the solar module 1 with that arranged thereon

Frame element 6. In particular, the front surface of the

Front glass element 2 of the solar module 1 can be arranged at a distance from the module holding element 10 along the vertical direction z, in particular at a distance from a front side wall of the receiving section 12, when the leg section 6f of the frame element 6 bears against the wall 15. In this case, a load from the solar module 1 via the frame element 6 and the receiving section 12 into the

Module holding element 10 and are removed from there into the wall 15.

It is shown here that the module holding element 10 as a so-called

Double glass holding element is formed, which can hold adjacent solar modules 1, and for this purpose forms two receiving sections 12.

5 shows a schematic side view of solar modules 1 and one

Module holding element 13 in a further embodiment. The module holding element 13 forms a U-shaped receiving section 12 for an edge section,

in particular a transverse edge section of the solar module 1. It is shown here that the module holding element 13 forms only one such receiving section 12 and can therefore also be referred to as an individual glass holding element. In particular, the module holding element 13 has a wall fastening section 14 or forms it, which is attached to the wall 15. This wall fastening section 14 simultaneously forms a wall side of the receiving section 12. The

Wall fastening section 14 is designed in such a way that a section of frame element 6, in particular leg section 6f explained above, can be supported on an end face of wall fastening section 14 if one

Solar module 1 is arranged in the receiving section 12.

A height of the receiving section 12 is greater than a sum of the thickness of the

Glass elements 2, 3 of the solar module 1, but smaller than a total thickness of the

Solar module 1 with a frame element 6 arranged thereon. Again, a transverse edge of the solar module 1, in particular the frame element 6 arranged thereon, rests on a bottom surface of the receiving section 12. The front surface of the

Solar module 1 is spaced from the module holding element 13, in particular from the front side wall of the receiving section 12, along the vertical direction z.

In this case, a load can be transferred from the solar module 1 via the frame element 6 and the receiving section 12 into the module holding element 13 and from there into the wall 15.

FIG. 6 shows a schematic side view of solar modules 1 with frame elements 6 and a module holding element 36 in a further embodiment. The module holding element 36 has an L-shaped profile in cross section. Here, one of the legs of the module holding element 36 is designed as a holding section 9, which is arranged in the receiving section 8 of the frame element 6 shown in FIG. 3.

It is also shown that the module holding element 36, in particular the holding section 9, has a through opening through which a fastening screw 11 can be fastened to the wall 15. A second leg of the module holding element 36 is oriented at right angles to the first leg and bears against the wall 15.

The module holding element 36 shown in FIG. 6 can also be referred to as a mounting bracket. In this case, a load can be transferred from the solar module 1 via the frame element 6 and the holding section 9 into the module holding element 36 and from there into the wall 15. FIG. 7 shows a schematic side view of solar modules 1 with frame elements 6 and a module holding element 16 in a further embodiment. This module holding element 6 has both a holding section 9 and at the same time forms a receiving section 12 for receiving an edge section, in particular one

Transverse edge section, of the solar module 1. The module holding element shown in Fig. 6

14 can also be referred to as a combined single glass holding and fastening angle element.

It is shown that the holding section 9 of the module holding element 16 is formed by one leg of the U-shaped receiving section 12 of the module holding element 16. It is also shown that the module holding element 16 has a

Has wall fastening section 14, via which the module holding element 16 is fastened to the wall 15. It is shown, as also in FIGS. 4 and 5, that a

transverse end face of the solar module 1, in particular a frame element 6 arranged thereon, rests on a bottom surface of the receiving section 12. In this case, a load from the solar module 1 via the frame element 6 and the

Retaining section 9 are removed in the module holding element 16 and from there into the wall 15. At the same time, a load can be transferred from the solar module 1 via the frame element 6 and the receiving section 12 into the module holding element 16 and from there into the wall

15 are removed.

8 is a schematic side view of solar modules 1 with frame elements 6 and a module holding element 36, which is similar to that shown in FIG. 6

Module holding element 9 is shown. In contrast to the embodiment shown in FIG. 6, the solar module 1 is via the module holding element 36 on a horizontal locking element 17 of a mullion-transom construction, the one

Forms holding device for the solar modules 1, attached. The locking element 17 is designed as a hollow profile element, which has a square or rectangular cross section.

9 shows a schematic side view of solar modules 1 with frame elements 6 and a module holding element 18 in a further embodiment, which enables the solar module 1 to be fastened to a locking element 17 of a mullion-transom construction. The module holding element 18 forms a receiving section 12 for receiving an edge section of the solar module 1. It is further shown that the

Module holding element 18 comprises an angle section 38 and a latch fastening section 37, which in turn has a through opening for receiving a

Fastening screw 11, wherein the module holding element 18 by means of

Fastening screw 1 1 screwed to the locking element 17 and thus can be fastened. The angle section 38 can be fastened to the transom fastening section 37, these sections 38, when fastened to one another, forming a U-shaped section which forms the receiving section 12.

Again it is shown that a height of the receiving section 12 of the

Module holding element 18 is greater than a sum of the thicknesses of the glass elements 2, 3 of the solar module 1, whereby the front surface of the solar module 1 can be arranged at a distance from the module holding element 18, in particular from the front side wall of the receiving section 12, if an edge section of the

Solar module 1 is arranged in the receiving section 12.

It can be seen from FIGS. 4, 5, 6, 7, 8 and 9 that module holding elements 10, 13, 16, 18, 36 can be designed in any shape and a holding section 12 for holding the solar module 1 for holding an edge section of the solar module 1 and / or can have a holding section 9 for arrangement in a receiving section 8 of a frame element 6. In particular, it can be seen that different types of module holding elements 10, 13, 16, 18, 36 enable load transfer via a receiving section 12 and / or via a holding section 9.

Fig. 10 shows a schematic plan view of several solar modules 1, which

Bolt elements 17 of a mullion-transom construction are fastened with transom elements 17 and mullion elements 19. Here, locking elements 17 extend along a direction parallel to the transverse axis x and post elements 19 parallel to the longitudinal axis x.

It is shown here that transverse edges of solar modules 1 arranged side by side, in particular along the longitudinal axis x side by side, can be attached to opposite sides of a locking element 17. It is shown that a first solar module 1 a in a first and a different further edge section of the solar module 1a is fastened to the locking element 17 via a module holding element 16 (see FIG. 7), this module holding element 16 having both a receiving section 12 for receiving the solar module 1a and a holding section 9 for arrangement in a receiving section 8 of a frame element 6 of this first Has solar module 1a.

It is further shown that a second solar module 1 b fastened on the opposite side of the locking element 17 is fastened to the locking element 17 in a first and a different further edge section of this solar module 1 b via a module holding element 13 (see for example FIG. 5) this module holding element 13 has a receiving section 12 for receiving the edge section of the second solar module 1 b, but no holding section 9 for arrangement in a corresponding one

Receiving section 8 of the frame member 6.

It is also shown that the module holding elements 13, 16, via which the solar modules 1 a, 1 b are fastened to the locking element 17, are arranged offset with respect to one another along the locking element 17, that is to say along a direction parallel to the transverse axis y. Also shown are a third and a fourth solar module 1 c, 1 d, which are also on

opposite sides of this locking element 17, but along the

Post element are arranged next to the solar modules 1 a, 1 b. Here, the third solar module 1 c is in different edge sections via module holding elements 13, as already explained above, and also via a module holding element 36

Post element locking element 17 attached. The module holding element 36 here does not have a receiving section 12 for receiving the edge section of the third solar module 1 c, but a holding section 9 for arrangement in a not shown

Frame element 6 of the third solar module 1c. The fourth solar module 1 d is fastened to the locking element 17 in various edge sections via module holding elements 13.

Again, the module holding elements 13, 36 of the third and fourth solar modules 1 c, 1 d along the locking element 17, that is to say in particular along the direction parallel to the transverse axis y, are offset from one another.

FIGS. 11 and 12 schematically show top views of solar modules 1 that are

Bolt elements 17 of a mullion-transom construction are attached, in particular via Module holding elements 13, 16, 18, 36 (see, Fig. 4, 5, 6, 7, 8 and 9). It is shown here that the solar modules 1 only cross these edges

Module holding elements 13, 16, 18, 36 are attached to the locking elements 17.

Longitudinal edges of the solar modules 1 are not fastened to locking elements 17 or locking elements, post elements 19 (see, for example, FIG. 10).

In contrast to FIG. 11, FIG. 12 shows an embodiment with intermediate locking elements 20. These intermediate locking elements 20 extend as

Bolt elements 17 parallel to the transverse axis y. The solar modules 1 are over

Module holding elements 13, 16, 18, 36 attached to these intermediate locking elements 20. These intermediate locking elements 20 also serve to prevent excessive deflection of the solar modules 1 in the state fastened to the mullion-transom construction. This allows larger solar modules 1 to be attached to the mullion-transom construction.

FIGS. 13 and 14 show schematic top views of solar modules 1, which are fastened to post elements 19, which extend along a longitudinal axis x.

In contrast to FIG. 13, the embodiment shown in FIG. 14 comprises so-called intermediate post elements 21, which likewise extend along the longitudinal axis, that is to say parallel to the post elements 19. Here, the solar modules 1 are also fastened to these intermediate post elements 21 via module holding elements 13, 16, 18, 36. As in the exemplary embodiment shown in FIG. 12, these serve to prevent excessive deflection of the solar modules 1. In this way, larger solar modules 1 can be attached to the mullion-transom structure.

FIG. 15 shows a schematic top view of solar modules 1 which are fastened to a mullion-transom structure which forms a holding device for the solar modules 1. The mullion-transom construction comprises transom elements 17 and

Post elements 19. Here, the solar modules 1 both in the range of

Longitudinal edges as well as in the area of the transverse edges via module holding elements 13, 16, 18, 36 (see FIGS. 4, 5, 6, 7, 8 and 9) on locking elements 17 and also on the post elements 19 are attached. 16 shows a schematic side view of solar modules 1 according to the invention in a further embodiment and a module holding element 22 in a further embodiment for fastening the solar modules 1 to a wall 15.

In contrast to the embodiment of the solar module 1 shown in FIG. 1, the solar modules 1 are not designed as stepped glass modules. In particular, a width of a first front glass part element 2a of the front glass element 2 corresponds to a width of the second front glass part element 2b and a width of a functional glass element 3. Likewise, a length of the first front glass part element 2a corresponds to a length of the second front glass part element 2b and a length of the functional glass element 3.

It is further shown that the module holding element 22 has a receiving area 12 for receiving the solar module 1, wherein a height of this receiving area 12 along the vertical axis z is greater than a total thickness of the solar module 1. The solar module 1 has no frame element 6.

It is further shown that the solar module 1 rests on a bottom surface of the receiving volume 12 via a support element 23, which can be designed in particular as a plastic rail element. Like a frame element 6, the support element 23 advantageously prevents glass of the solar module 1 from coming into direct mechanical contact with the bottom surface of the receiving section 12.

Also shown are protective elements 24, which can be made of EPDM rubber, for example. These are arranged between a front surface of the solar module 1 and a front side wall of the receiving volume 12 and between a rear surface of the solar module 1 and a rear side wall of the receiving volume 12.

The module holding element 22 has a T-shaped wall-side part element 25, which has a threaded bore for receiving a fastening screw 11. The module holding element 22 further comprises a rod-shaped part element 26 which has a through opening for receiving the fastening screw 11 and can thus be screwed onto the T-shaped part element 25. The T-profile-shaped partial element 25 is fastened to the wall 15 by means of fastening means, not shown. Here, the T-profile-shaped sub-element 25 and the part on it screwed rod-shaped partial element 26 on the receiving section 12, the rod-shaped partial element 26 forming the front side wall of the receiving section 12 and the T-shaped partial element 25 forming the bottom surface and the rear side wall of the receiving section 12.

FIG. 17 shows a schematic side view of solar modules 1 according to the embodiment of the solar modules 1 shown in FIG. 3. These are fastened to the wall 15 with the module holding element 22 shown in FIG. 16. It can thus be seen that this module holding element 22 is also suitable for fastening solar modules 1 of another embodiment according to the invention. In contrast to the embodiment shown in FIG. 16, however, the solar module 1, in particular its end face on the lateral edge, is not supported by a support element 23 but only by the frame element 6 on the bottom surface of the receiving volume 12, since the frame element 6 takes over the function of this support element 23 , However, the protective elements 24 are still present, which are between a front

Surface of the solar module 1 and the front side wall of the

Receiving section 12 and between the frame member 6 and a rear side wall of the receiving section 12 of the module holding member 22 are arranged.

18 shows a schematic side view of solar modules 1 in a further embodiment. In contrast to that shown in Fig. 16

Embodiment include the solar modules 1 in addition to the front glass element 2, which consists of the first front glass element 2a and the second

Front glass part element 2b, and the functional glass element 3 a fourth glass element 27. It is shown here that a width of the fourth glass element corresponds to a width of the front glass element 2 and the functional glass element 3. A length of the fourth glass element 27 also corresponds to a length of the front glass element 2 and the functional glass element 3. The fourth glass element 27 can in particular be designed as a single-pane safety glass element or as a laminated safety glass. It is shown here that the fourth glass element 27 is arranged along the vertical axis z at a distance from, in particular behind, the functional glass element 3, in particular at a distance from its rear surface. Thus, an intermediate space 28 is enclosed between the functional glass element 3 and the fourth glass element 27, which can serve for the thermal insulation of the functional glass element 3. Also shown is a spacer element 29, which between the Functional glass element 3 and the fourth glass element 27 is arranged, in particular between the outer edge portion of these glass elements 3, 27. Such a solar module 1 can be particularly suitable for use in a warm facade.

19 shows a schematic side view of solar modules 1 in a further embodiment. In contrast to that shown in Fig. 16

Front glass part element 2b, and the functional glass element 3 a fourth glass element 27. It is shown here that a width of the fourth glass element corresponds to a width of the front glass element 2 and the functional glass element 3. A length of the fourth glass element 27 also corresponds to a length of the front glass element 2 and the functional glass element 3. The fourth glass element 27 can in particular be designed as a single-pane safety glass element or as a laminated safety glass.

In contrast to the exemplary embodiment shown in FIG. 18, the fourth glass element 27 is arranged along the vertical axis z at a distance from, in particular in front of, the first front glass part element 3, in particular at a distance from its front surface. A space 28 is thus enclosed between the first front glass part element 3 and the fourth glass element 27.

Also shown is a spacer element 29, which is arranged between the first front glass part element 2a and the fourth glass element 27. Such a solar module 1 can be particularly suitable for use in a warm facade.

FIG. 20 shows a schematic side view of solar modules 1 which are designed in accordance with the exemplary embodiment shown in FIG. 3. A section of the solar modules 1 is shown in which no module holding element 10, 13, 16, 18, 22, 36 is arranged. These solar modules 1 can in particular be arranged next to one another along the longitudinal axis x.

A sealing element 31 is shown, which is arranged between the two adjacent solar modules 1, in particular between the end faces of these solar modules 1 on the transverse edge. This allows an area between the wall 15 and the rear surfaces of the solar modules 1 to be sealed, in particular against Humidity. It is shown that the sealing element 31 has a convex surface, in particular one that is curved outwards along the vertical direction z. The

Sealing element 31 can in particular be made of silicone. Also shown is e.g. Round cord 32 made of foam, which can be designed in particular as a so-called light cord, further in particular as a foam light cord. The round cord 32 can thus form a lighting element. This is arranged on a rear surface of the sealing element 31 and thus lies in the sealed area between the wall 15 and the sealing element 31.

FIG. 21 shows a schematic side view of solar modules 1 according to the exemplary embodiment shown in FIG. 3. In contrast to that in FIG. 20

In the illustrated embodiment, the sealing element 31 has a concavely curved, that is to say in particular curved inward along the vertical direction z

As already explained with reference to FIG. 20, this seals an intermediate space between the rear surface of the solar modules 1 and the wall 15. The sealing element 31 can in particular be designed as a prefabricated element.

It is shown here that this sealing element 31 has an outer surface which is convexly curved in the vertical direction z and an inner surface which is convexly curved in the opposite direction to the vertical direction z.

FIG. 23 shows a schematic side view of solar modules 1, between the solar modules 1, corresponding to that shown in FIG. 20

Embodiment, a sealing element 31 and a lighting element 44 is arranged. In contrast to the embodiment shown in FIG. 20, a solar module comprises further lighting devices 33, in particular as light-emitting diodes can be trained. These further lighting devices 33 are here on one end face, in the embodiment shown in FIG. 23 on one

transverse edge end face, the first front glass part element 2a and the second

Front glass part 2b arranged. Here, the lighting devices 33 are arranged in such a way that they fit into the corresponding glass part elements 2a, 2b

can radiate into it. Here, these further lighting devices 33 can e.g. be embedded in the silicone or PU layer 7 between or behind the front glass part elements 2a, 2b and the frame element 6. This advantageously results in indirect and controllable illumination of the front glass part elements, which is suitable for

Can be used for lighting and advertising purposes.

This has the technical effect that e.g. by machining the

Solar module 1 in the area of the back of the first front glass element 2a or the front of the second front glass element 2b or by integrating

refractive material in the intermediate layer 4 or 5, a luminous area can be defined, which emerges in terms of intensity and edge sharpness as a luminous area in relation to its surroundings.

24 shows a schematic side view of solar modules 1 as in the exemplary embodiment shown in FIG. 23. In contrast to the exemplary embodiment shown in FIG. 23, the further lighting devices 33 are not arranged on the end face of the solar module 1 but in the sealing element 31, in particular lighting devices designed as LEDs. That's further

Sealing element 31 is made transparent for radiation emitted by these further lighting devices 33. Furthermore, the sealing element 31 has a coating 30 reflecting toward the sealing element 31 on the outer surface, that is to say the convex curved surface on the front. Here it can

Sealing element 31, in particular the outer surface and / or the reflecting layer 30, are arranged and / or configured such that the radiation emitted by the further lighting devices 33 is reflected by this reflecting layer 30 into the solar modules 1, in particular into the first front glass part element 2a ,

This advantageously results in a homogeneous, flat and diffuse

Illumination made up of one or more colors or a combination thereof discreet, absolutely glare-free light radiates into the surroundings.

However, it is also conceivable that the sealing element 31 does not have a

reflective coating 30 is coated. In this case, the

Lighting devices 33, the sealing element 31 provide a light band, the radiation of which can be adjusted in color, intensity and function.

FIG. 25 shows a schematic side view of solar modules 1 according to the embodiment shown in FIG. 3, between which, as in the embodiment shown in FIG. 22, a sealing element 31 is arranged. in the

The difference from the embodiment shown in FIG. 22 is another

Lighting device 33 attached to the wall 15. The sealing element 31 is transparent for the radiation emitted by the further lighting device 33. Here, the further lighting device 33 is arranged relative to the sealing element 31 in such a way that radiation emitted by the further lighting device 33 can be radiated outward through the sealing element 31, that is to say toward a front surface of the solar modules 1.

An arrangement of solar modules 1 with a sealing element 27 as shown in FIG. 25 is shown in FIG. 26. In contrast to that shown in FIG. 25

The embodiment is the sealing element 31 as shown in FIG. 24

Embodiment provided with a reflective layer 30 which is arranged on an outer surface of the sealing element 31 and reflects radiation passing through the sealing element 31 towards the solar modules 1, in particular into the first front glass part elements 2a of these solar modules. The reflective layer 30 is thus arranged and / or configured such that radiation incident on the reflective layer 30 along the vertical direction z at least partially towards the

Solar modules 1, in particular towards the first front glass part elements 2a, is reflected.

However, it is also conceivable in this embodiment that the sealing element 31 is not coated with a reflective coating 30. In this case, the sealing element 31 can provide the lighting element 33 with a light band whose radiation can be adjusted in color, intensity and function. FIG. 27 shows a schematic side view of a solar module 1 according to the invention, which is essentially designed like the solar module 1 shown in FIG. 3. In contrast to the solar module 1 shown in FIG. 3, the solar module 1 shown in FIG. 27 comprises stabilizing elements 35. These stabilizing elements 35 are arranged between the first front glass part element 2a and the frame element 6. Another stabilizing element 35 is between the second

Front glass part 2b and the frame member 6 arranged. It is shown here that the stabilizing elements 35 are designed as angle profile elements.

In particular, the stabilizing elements 35 can be designed as plastic angles. These serve to transfer the load from the own load and to stabilize the

Solar modules 1, if these e.g. be placed on a bottom surface of a receiving section 12 of a module holding element 10, 13, 16, 18, 22, 36. It is shown here that these stabilizing elements 35 are only provided on a first edge section, in particular a first transverse edge, of the solar module, but not also on the opposite transverse edge. In particular, such stabilizing elements 31 can only be arranged on an edge which is placed on such a floor surface.

28 shows another embodiment of a solar module 1. It is shown that the front glass element is not designed as a step glass element. As a result, the solar module 1 is designed as a two-stage glass element, with corresponding dimensions, that is to say a length and a width, of the front glass part elements 2a, 2b being the same, but larger than corresponding dimensions of the functional glass element 3. A frame element 6 is also shown. This frame element 6 comprises as the embodiment shown in FIG. 3 also has a stepped section and a receiving section 8. In contrast to the embodiment shown in FIG. 3, the stepped section is formed by a first step section 6a, a second step section 6b and a third step section 6c. A fourth section 6d forms a leg section of a U-profile-shaped receiving section for a holding section 9 of a module holding element 14, 16 (see FIG. 6, FIG. 7). Thus, the stepped section of the frame element 6 is of two-stage and not three-stage cross-section. Next are stabilizing elements 35 between the first

Front glass element 2a and the frame element 6 arranged.

29 shows a further embodiment of a solar module 1. Frame elements 6 are shown, with a first frame element 39 on a lower one Transverse edge of the solar module 1 and a second frame element 40 is arranged on an upper transverse edge of the solar module 1. It is shown that the front glass element 2 is not designed as a step glass element.

It is further shown that the first frame element 39 is designed like the frame element 6 shown in FIG. 3. In particular, it comprises step sections 39a, 39b, 39c, 39d, 39e arranged at right angles to one another, which are arranged in the form of a step in cross-section, and a leg section 39f, the step sections 39d, 39e and the step section 39f forming a receiving section 8. The

Receiving section 8 serves for receiving a holding section 42 of a

Module holding element 43. A stabilizing element 35 is between the

Front glass part elements 2a, 2b and the frame element 39 are arranged.

The further frame element 40 comprises a first step section 40a and further step sections 40b, 40c as well as leg sections 40d, 40e. The arrangement of the step sections 40a, 40b, 40c is adapted to an edge profile of the upper transverse edge of the solar module 1. Furthermore, the step sections 40a, 40b, 40c and the leg sections 40d, 40e form a receiving section 41.

In other words, the further frame element 40 is designed as an agraffe-like holding frame element. In particular, the step sections 40a, 40b, 40c and the leg sections 40d, 40e form an agraffe. A further holding section 42 of the module holding element 43 or a holding section of a further module holding element or a facade can be introduced into the receiving section 41.

Thus, a load can be transferred from the solar module 1 via both frame elements 39, 40 and the module holding element (s) 43 into a wall 15, for example. LIST OF REFERENCE NUMBERS
