Description

[0001] The invention relates to a solar facade module for attachment to a building.

[0002] Given the increasing importance of renewable energies and the growing need for sustainable energy solutions, buildings are increasingly being equipped with facade-integrated solar modules. Such modules offer a way to utilize photovoltaic and solar thermal technology even in urban areas with limited roof space, or as a supplement to existing roof space.

[0003] Furthermore, the use of suitable solar modules on appropriate building surfaces, such as facades, unlocks previously untapped potential for generating electricity and heat from solar radiation. This not only contributes to a reduction in CO2 emissions but also offers an economically attractive solution for building owners who want to manage their energy consumption sustainably.

[0004] A key problem with using solar modules for facade mounting is the vulnerability of individual components to changing or extreme weather conditions. Building facades are generally highly exposed and thus subject to direct weather influences such as wind, rain, snow, hail, and temperature fluctuations. These factors can impair both the efficiency and the lifespan of the solar modules, potentially leading to reduced usability and cost-effectiveness.

[0005] The object of the present invention is to provide a solar facade module that offers improved protection for the solar modules.

[0006] The problem is solved by a solar facade module with the features of claim 1. Advantageous embodiments are specified in the dependent claims.

[0007] According to the invention, a solar facade module for attachment to a building comprises a support frame, at least one cover device held on the support frame, and at least one solar module for generating electricity and / or heat from solar radiation, wherein the solar module and / or the cover device is movably mounted on the support frame in such a way that the solar module is movable relative to the cover device, and wherein in a first operating position the solar module is covered by the cover device in such a way that the cover device achieves a protective covering effect on the solar module in a covering area of ​​the solar module, and in a second operating position the solar module is exposed by the cover device in such a way that the covering effect achieved in the first operating position is eliminated.

[0008] The solar panel cover provides protection against external weather conditions such as wind, hail, rain, snow, and other weather phenomena. Furthermore, the cover can also offer protection against unwanted sunlight, for example, to reduce energy production. Thus, the cover can provide both protection and / or power regulation.

[0009] The basic idea is that the solar facade modules according to the invention, which are attached to buildings, particularly building facades, should meet both aesthetic and functional requirements. The modules are designed to adapt flexibly to different building surfaces and facade types, enabling easy installation while ensuring maximum energy efficiency.

[0010] For use in photovoltaics, the solar module is designed to contain solar cells that generate electricity. Alternatively or additionally, the solar module could also include solar collectors to absorb and transport heat generated from sunlight.

[0011] A solar module equipped with solar cells can be electrically connected to an inverter in a familiar way to convert the generated direct current into alternating current and feed it into a power grid. The generated electrical energy can be used to power a building or a larger consumer network. Of course, the electrical energy can also be stored in storage devices such as batteries for later use.

[0012] The solar facade module according to the invention can, in principle, be installed on all suitable types of buildings. The intention is to utilize previously unused surfaces, such as the exterior walls of towers or walls. A module according to the invention can also be installed on the roofs of buildings. Preferably, the solar facade module is designed for attachment to a building wall, in particular to a facade.

[0013] In a first conceivable embodiment, it can be provided that the covering device has at least one plate-shaped covering element by means of which a covering effect protecting the solar module can be achieved.

[0014] The cover elements serve to protect the solar modules. The solar modules and / or the cover elements can be moved or adjusted manually or automatically so that the solar modules are covered and thus protected within a designated area.

[0015] The cover elements can be made of materials suited to the required protection rating. For example, the cover elements can be made partially or entirely of wood, plaster, marble, concrete, ceramic, or other materials. It is also possible for the cover elements to have multiple layers, with the outermost layer serving as a visible and / or protective layer. In addition to protecting the solar modules, other functional or aesthetic criteria, such as the building design, can also be considered when selecting the material. The choice of material and / or the external appearance of the cover elements can create a decorative effect that tailors the building's appearance to the user's preferences.

[0016] In a preferred embodiment, the solar module is movably mounted on the support frame, and the solar module is movable beneath the cover, which is preferably fixed to the support frame. It is also conceivable that the solar modules are fixed to the support frame and the cover is movable. Finally, it is also conceivable that both the cover has movable components and that the solar modules are movably mounted.

[0017] In a further embodiment, it is conceivable that the solar facade module has a folding mechanism implemented by means of an angle adjustment device, allowing the solar modules to be positioned at a different angle relative to the support frame. Such adjustability, particularly depending on the position of the sun, can improve the utilization of available solar radiation.

[0018] The solar facade module is designed to have a drive system that allows the solar module and / or the cover to be moved relative to each other. Depending on the installation location or other parameters, various drive mechanisms can be used to move the solar module and / or the cover. For example, depending on the load on the moving parts and the mounting location, cable pulleys or linear actuators can be used to move the solar module and / or the cover.

[0019] In principle, a solar facade module according to the invention can have only a single solar module. Preferably, however, the solar facade module has at least two separate solar modules that can be covered by means of the covering device. Preferably, the covering device has a cover element for each solar module, by means of which a protective covering effect can be achieved for the solar module associated with the cover element. The number of solar modules can depend, for example, on the intended mounting location or on the mass of the module in the desired configuration. If lightweight materials such as wood, aluminum, or plastics are used for the support frame or the cover plates, the overall weight of the solar facade module is significantly lower when using multiple solar modules than when using heavier materials such as marble or ceramic. The weight, and thus potentially theThe number of solar modules per solar facade module may also be specified by building regulations. For example, a greater weight per solar facade module may be permitted when mounted on a roof than when mounted on a [unclear - possibly a surface or structure].

[0020] The movement mechanism of the solar modules or the covering device can be designed such that all solar modules or the covering of all solar modules occurs simultaneously. In a preferred embodiment, however, it is intended that the solar modules can be moved independently of one another.

[0021] To simplify repairs and / or to allow for quick changes to the external appearance of the solar facade module, the cover system is designed to have cover elements that are removable and attached to the support frame, and / or are designed so that a surface area of ​​the cover elements is replaceable.

[0022] In principle, it can be provided that the angle of the solar modules to a mounting surface in the mounting area of ​​the solar facade module is fixed. In particular, it can be provided that this angle is approximately the same in every operating position. As already explained, alternatively, it can be provided that the solar modules are designed to be adjustable in their angle, for example, to allow alignment with the sun's position. Against this background, one embodiment envisions that the solar module in the second operating position is arranged at least partially across its surface, and that at least some surface areas of the solar module in the second operating position are arranged at an angle, wherein the angle is inclined relative to a mounting surface of the solar facade module and / or wherein the angle relative to a mounting surface of the solar facade module is adjustable.

[0023] The invention will be explained in more detail below with the aid of figures. These show Fig. 1 a schematic representation of a solar facade module according to the invention in a top view from the front in a second operating position with exposed solar modules, Fig. 2 a schematic representation of a solar facade module according to the invention in a sectional view from the side in a second operating position with exposed solar modules, Fig. 3 a schematic representation of a solar facade module according to the invention in a sectional view from the side in a first operating position with covered solar modules, and Fig. 4 a schematic representation of a solar facade module according to the invention in an isometric side view in a second operating position with exposed solar modules.

[0024] Fig. Figure 1 shows a solar facade module 10 according to the invention, comprising a support frame 12 and a cover device 14 held on the support frame 12. The cover device has two flat cover plates 18a, 18b. In the present embodiment, the solar facade module 10 has two solar modules 16a, 16b, each of which can be moved upwards behind a cover plate 18a, 18b arranged above it. Fig. Figure 1 shows the solar facade module 10 in an operating position in which the solar modules 16a and 16b are exposed. The solar modules 16a and 16b can thus be exposed to sunlight in order to utilize solar energy to generate electricity or heat.

[0025] Two drive units 22a, 22b are shown with dashed lines, each intended to drive the solar modules 16a, 16b. The drive units 22a, 22b are arranged behind the cover plates 18a, 18b and are thus protected from environmental influences.

[0026] In the lower area of ​​the solar facade module 10 a blanking plate 24 is arranged, which at least on its outside is designed analogously to the cover plates 18a, 18b.

[0027] In the Fig. Figures 1 to 4 show solar facade modules 10 equipped with two solar modules 16a, 16b and two cover plates 18a, 18b, as well as a blanking plate 24. It is understood that the solar facade modules 10 can also have more than two solar modules 16 and correspondingly more cover plates 18. Preferably, a blanking plate 24 is provided in each case to ensure a symmetrical exterior appearance in an operating position where the solar modules 16 are retracted behind the cover plates 18.

[0028] In Fig. Figure 2 shows a schematic cross-sectional view of a solar facade module 10 from the side. The construction essentially corresponds to the solar facade module from Fig. 1. The solar modules 16a, 16b are clearly visible in a position exposed by the overlying cover plates 18a, 18b. In this position, the solar modules 16a, 16b can be exposed to solar radiation for energy generation. A schematic representation shows an upper drive unit 22a and a lower drive unit 22b, each located behind the cover plates 18a and 18b, respectively. The upper drive unit 22a is configured to move the upper solar module 16a. The lower drive unit 22b is configured to move the lower solar module 16b. As indicated, the drives 22a, 22b can be equipped with guide devices 28 designed as cable pulls, by means of which the solar modules 16a, 16b can be pulled upwards behind the cover plates 18a, 18b. A cable pulley can be designed in such a way that it pulls the solar modules upwards into a protective position and, under the influence of gravity, lowers them downwards into the exposed position.Alternatively, it can also be provided that the solar modules are moved by a guided motion, particularly in the up and down movement. This guided movement is advantageous, for example, in situations where the solar facade module 10 according to the invention is arranged in a horizontal orientation or at a very shallow angle to the horizontal. In such installation positions, the solar module 16 cannot be moved out of the protective position behind the cover device 14 by gravity alone, or only insufficiently.

[0029] The guide device 28 can alternatively or additionally include guide rails or the like, by means of which the solar modules 16a, 16b are positively guided. Besides cables, other drive devices such as linear drives, rack and pinion drives, or the like are also conceivable for moving the solar modules 16a, 16b or for moving the cover plates 18a, 18b (different configuration). Independently of the drives, an angle adjustment device (not shown) can also be provided, by means of which the solar modules 16a, 16b can be individually or jointly positioned at an adjustable angle relative to the support frame. This allows the solar modules 16a, 16b to be aligned with the position of the sun.

[0030] In Fig. Figure 3 shows the solar facade module 10 in an operating position in which the solar modules (16a, 16b) are covered by the cover device (14) in a first operating position such that the cover device (14) achieves a protective covering effect on the solar module (16a, 16b) in a covering area of ​​the solar module (16a, 16b) and the solar module (16a, 16b) is exposed by the cover device (14) in a second operating position such that the covering effect achieved in the first operating position is eliminated.

[0031] As in the Fig. 2 and Fig. As schematically indicated in Figure 3, the facade module 10 can be attached in a fastening area of ​​a structure, such as the facade of a building 20, by means of spacers 32.

[0032] Fig. Figure 4 shows the solar facade module 10. Fig. Figure 1 in an isometric view. The inclined orientation of the cover plates 18a, 18b and the approximately parallel arrangement of the solar modules 16a, 16b are clearly visible. As in Fig. As can be seen in Figure 4, the support structure 12 can have two side walls 26. The drive unit 22 and other components, such as the cover elements 18 and the blanking plate 24 of the solar facade module 10, can be mounted on the inner sides of these side walls 26. Guide devices and / or angle adjustment devices (not shown) for the solar modules 16 can also be attached to the side walls 26. The side walls 26 are shown in the examples of Fig. 1 to 4 connected to a rear wall 30 of the support frame 12.
