Description

State of the art

On commercially used areas such as cultivation areas for useful or cultivated plants or other outdoor areas, roofing systems, for example in lightweight construction, are regularly used to provide a protective roof above the area to be protected.

The roofing that can be provided, in particular convertible and demountable, serves, for example, to protect agricultural areas from weather conditions, birds or insects or to protect crops from weather-related damage such as frost, hail, rain damage and/or to protect against bacterial or fungal plant diseases .

In this context, climate change is also posing growing problems for a large number of companies in the agricultural sector.

Global developments with regard to efficient and ecologically advantageous energy provision are also playing an increasingly important role.

Task and advantages of the invention

The object of the present invention is to provide a device for roofing areas of the type described in the introduction, such as roofing systems for agriculture, in a technically efficient and economically advantageous manner. In particular, local and global challenges with regard to climate change and ecological energy production strategies away from fossil fuels should be solved in a practical manner.

The present invention is based on a device for roofing an outdoor area, such as cultivation areas for cultivated or useful plants or other commercially used areas, comprising a surface element and a support arrangement with supports, the support arrangement being anchorable to a floor surface of the area, and wherein the surface element carried by the support arrangement serves to form a flat protective roof above the area, with a section of the surface element extending along a ridge region of the protective roof. For example, an edge section of the surface element extends along the ridge area.

For example, the spaced apart supports extend in the vertical direction from below, for example from the floor surface, into the ridge area of the device. For example, in the ridge area there is a ridge element of the support arrangement that is elongated transversely to the vertical and offset vertically to the floor surface in the ridge area. For example, the ridge element is accommodated at the upper ends running between spaced upper ends of the supports.

For example, the protective roof is used to cover crops such as crops, fruit, vegetables, fodder plants or plants as energy raw materials. For example, the protective roof is a foil roof. For example, the protective roof does not have any rigid struts or profiles on its surface. For example, the protective roof is spatially braced and/or stretched by tensile forces acting on the edge.

The vertical direction is in particular a height direction of the device. The ridge element, such as a wire, a wire rope, a plastic rope, and/or a rod-shaped elongated profile, runs at least approximately in a horizontal direction and can absorb forces in the longitudinal and/or transverse direction of the ridge element. For example, the ridge element is taut. For example, the protective roof is spread out and stretched above or over the area or the protected or useful area outdoors.

For example, one side of the surface element extends with z. B. a straight longitudinal or transverse edge of the surface element along the ridge element. For example, the side in question forms an upper ridge-side edge of a side of a region of the surface element or protective roof that extends over the length of the ridge element. As a rule, partial areas of the surface element or the protective roof are present on the ridge element laterally on both sides over the length of the ridge element, for example inclined downwards to the horizontal. For example, the protective roof has the shape of an equilateral gable roof in relation to a ridge element. For example, a floor plan of the surface element or the protective roof is square-shaped, such as: B. rectangular-shaped.

For example, the surface element is single-layered or multi-layered or multi-layered. For example, the surface element is formed from exactly two layers or layers, a top and a bottom layer or layer. For example, the surface element is formed from exactly three layers. The layers are e.g. B. layered e.g. B. formed one on top of the other.

For example, the surface element comprises a film such as a plastic film. For example, the surface element comprises exactly one hanging foil. For example, the surface element includes a network element such as. B. a mesh fabric. For example, the surface element comprises exactly one connected network element such as a network fabric. For example, on exactly one lower network element, exactly one film layer is present above the network element. For example, the film has several parallel film strips. For example, the network element is designed to be continuous or in one piece.

For example, the multiple layers or the multiple layers of the surface element are each designed as a thin, flat, closed or perforated material. For example, the surface element comprises a film, a net element, a textile material or a fleece. For example, the surface element is flexible or deformable, for example can be rolled up and unrolled. For example, the film is transparent or partially transparent. For example, the film has a thickness between 0.1 millimeters and 3 millimeters.

For example, the surface element comprises exactly one underlying net element or exactly one net such as a hail or insect protection net. For example, the surface element comprises a layer above the network element. For example, the surface element comprises exactly one underlying network element, e.g. continuously flat or in one piece or in one piece and one above it, for example. B. existing film lying on top. For example, the film forms exactly one layer above the net element, possibly only slightly overlapping the edge of an adjacent film strip. For example, the film is made up of several parts, for example formed from several parallel film strips. For example, the several film strips are rectangular in plan and are present next to each other, which do not overlap or only overlap at the edges. For example, the film is alternatively connected in one piece, e.g. B. formed over the entire protective roof. For example, the film is in one piece, e.g. B. formed over an entire half area of a gable roof-shaped protective roof or over one half or an inclined side of the gable roof-shaped protective roof.

For example, the surface element comprises exactly one layer of one material or two or more layers or layers of materials, and comprises, for example. B. several upper parallel rectangular film strips, for example slightly overlapping at the edge, and underneath a carrier such as. B. a net, for example a hail or insect protection net.

For example, along a longitudinal edge of a film strip, this is fixed to the carrier underneath, such as. B. a network carrier. For example, a longitudinal edge of the film strip opposite the fixed longitudinal edge is freely movable and can be reversibly deflected upwards, for example by wind or thermals.

For example, the device is an agricultural canopy system such as. B. a crop plant or fruit and/or vegetable canopy system.

One aspect of the invention is that a solar cell module is provided which is connected to the surface element, so that when light is irradiated on the solar cell module, light energy can be converted into electrical energy, quick-release fastening means comprising zipper means with a zipper unit being provided, in order to detachably arrange a solar cell module on the surface element using the zipper means.

This allows various advantages to be achieved in everyday practice.

Zipper devices can be operated intuitively and manually by anyone, as zipper devices are items of daily use.

A possibility of ecological energy production provided by the solar cell module is implemented integrally in the roofing system with the attached solar cell module, for example in an otherwise conventionally designed roofing system. For example, the solar cell module can be integrated into a commonly designed roofing device. Existing and known devices for roofing can be used to use energy through photovoltaics with little effort and/or without significant change measures. Only the zipper means need to be implemented. For example, the support arrangement of known roofing systems or devices can be used in the existing configuration or identically and an existing surface element can be used to arrange the solar cell module.

For example, the solar cell module is a thin, flat component.

The solar cell module can be attached to all devices, e.g. B. can be used for agricultural cultural protection, regardless of which area or culture is specifically covered. The solar cell module can be releasably integrated with zipper means, regardless of the specific type of surface element installed, such as foil, hail and/or insect protection surface elements are used variably or universally.

For example, the solar cell module can either be attached or installed quickly and easily in the roofing device. For example, the solar cell module can be removed from the roof and/or replaced when not in use or for other reasons, e.g. B. for repair purposes, and / or attached to another roofing device or z. B. be stowed away.

With the solar cell module as part of the roofing, the solar cell module can also be used all year round. For example, even in a dual function, e.g. B. when the solar cell module serves as a protective jacket for an area of the surface element that is kept compressed underneath, in addition to the function of year-round production of electrical energy. For example, due to the solar cell module, the winterization and storage of the surface element at another location, which was otherwise or previously necessary, can be eliminated, which is time-consuming.

For example, the solar cell module is present lying directly adjacent to a top side of a section of the surface element. For example, the solar cell module is detachably arranged on the surface element exclusively via the zipper means or solely via the zipper means.

For example, the top of the section of the surface element is z. B. formed flat in a plane. For example, the solar cell module is usually flat and aligned on the device in the energy generation state. For example, regardless of the solar cell module, e.g. B. is tensioned across the surface, remaining sections of the protective roof are also tensioned.

For example, the top of the section of the surface element and thus the solar cell module that is detachably connected to it is oriented outwards towards the atmosphere and thus towards the sun. The spatial orientation of the attached solar cell module such as: B. the inclination to the horizontal is advantageous for optimal performance of the solar cell adapted to the sunlight. The solar cell module is present on the outside over an area of the surface element and covering it. For example, in the clamped state, the solar cell module can be integrated into the surface element according to the flat extent or a plane formed. For example, the level formed by the solar cell module is z. B. parallel to a plane spanned by the flat surface element. For example, the solar cell module and the underlying surface element section form a multi-layer structure such as a two- or three- or four-layer structure.

For example, in the case of the protective roof, the solar cell module forms a partial surface area of the surface element or a top or outside partial area of the protective roof. For example, the solar cell module is strip-shaped as a coherent functional unit for energy conversion. The length of the solar cell module is, for example, equal to or almost corresponding to a length of the coherent unit of the surface element or the relevant section of the surface element. For example, the length of the solar cell module corresponds to a partial length of the coherent unit of the surface element or the relevant section of the surface element.

For example, a zipper unit has a slider and two elongated side parts that can be releasably hooked together.

For example, the zipper means are designed as connecting means that work on the principle of a zipper. For example, zipper means also include zipper closure means with a zipper closure unit. The zipper means are available as a proven, robust standard product in a wide variety of configurations. The zipper means represent an easy-to-open closure means that is based on positive locking. For example, a longitudinal axis of the zipper unit extends in the longitudinal direction of the ridge element, for example horizontally and/or parallel to the longitudinal axis of the ridge element.

For example, a longitudinal axis of the zipper unit extends in the vertical direction and/or transversely to the longitudinal direction of the ridge element. For example, a solar cell module has exactly one zipper unit or exactly two zipper units or more than two zipper units. For example, a solar cell module has a first zipper unit and a second zipper unit. For example, the longitudinal axis of the first zipper unit is aligned parallel to the longitudinal axis of the second zipper unit. For example, the longitudinal axis of the first zipper unit is not parallel, for example. B. aligned transversely to the longitudinal axis of the second zipper unit. For example, in a solar cell module with a square floor plan, there are two spaced-apart and parallel-offset zipper units whose longitudinal axes are parallel.

For example, in a square solar cell module there are two spaced apart ones and parallel offset first zipper units are present, whose longitudinal axes are parallel to one another, and in addition two further spaced and parallel offset second zipper units are present, whose longitudinal axes are parallel to one another and transverse to the longitudinal axes of the first zipper units. For example, the zipper means form a frame-like arrangement externally along the edges of the solar cell module.

For example, a solar cell module is a unit that is designed to convert light energy into electrical energy or is suitable for generating electricity. For example, the solar cell module comprises exactly two or more than two sub-units or several sub-units that form the solar cell module can work together to generate electricity, for example be electrically connected.

For example, exactly one zipper unit is provided for several connected solar cell sub-units or there are several zipper units for several connected solar cell sub-units.

A further aspect of the invention can be seen in the fact that a solar cell module is provided, which is connected to the surface element, so that when light is irradiated on the solar cell module, light energy can be converted into electrical energy, with quick-release fastening means comprising Velcro fastening means with a Velcro fastener unit are provided in order to releasably arrange a solar cell module on the surface element using the Velcro fastening means.

This means that the connection with the Velcro fasteners can be set up or closed and removed or released again quickly, easily and reversibly as often as desired. This is done e.g. B. manually, intuitively and in just a few steps.

For example, a Velcro fastener unit has two flat, flexible Velcro strips that can be reversibly and detachably hooked together. A Velcro fastener unit is, for example, strip-shaped or flat. The two Velcro strips include e.g. B. a first Velcro strip with flexible loops, e.g. B. a fleece ribbon. The two Velcro strips include e.g. B. a second Velcro strip with flexible barbs, e.g. B. a hook strap. The first Velcro strip can be reversibly hooked to the second Velcro strip, e.g. B. by pressing each other. For example, a Velcro strip of the Velcro fastener unit is z. B. permanently attached to the surface element. For example, a first or second Velcro strip of the Velcro fastener unit is sewn, glued, welded or attached in one piece to the surface element. The same applies to the attachment of the other Velcro strip, e.g. B. the second or first Velcro strip of the Velcro unit on the solar cell module.

The orientation or arrangement of a Velcro fastener unit is, for example, in the longitudinal direction of the ridge area or in the longitudinal direction of the ridge element. The orientation or arrangement of a Velcro fastener unit is, for example, transversely or obliquely to the longitudinal direction of the ridge area or to the longitudinal direction of the ridge element. For example, a Velcro fastener unit extends along a longitudinal edge of the solar cell module or a surface element or along a longitudinal edge of a strip-shaped region of the surface element.

For example, it is possible to provide several Velcro fastener units with the same and/or different orientation for connecting a solar cell module to the surface element. For example, exactly one Velcro fastener unit is provided per solar cell module for connecting to the surface element. For example, exactly two or exactly three or exactly four Velcro fastener units are provided per solar cell module for connecting to the surface element.

For example, the solar cell module is designed to be flexible. For example, the solar cell module has a shape-changing behavior without the function of energy conversion and/or provision suffering. For example, the solar cell module can be folded to save space. For example, the solar cell module is designed to be at least partially foldable, elastic, rollable and/or gatherable. For example, the solar cell module is designed with a comparatively small thickness in the millimeter range. For example, the solar cell module has a thickness in the one or two-digit millimeter range. For example, the solar cell module can be provided spread out over a large area.

For example, the solar cell module is designed as a film module.

For example, the solar cell module is designed to be flexible.

For example, the solar cell module can be designed or designed as a surface module.

For example, the solar cell module can be designed or designed as a winding module.

For example, the solar cell module can be rolled up or rolled up and rolled out again. For example, the solar cell module can be rolled up, for example. B. provide rolled up as a wrap. The rolled-up solar cell module is compact and can be provided in a space-saving manner, e.g. B. for storage or transport.

For example, the solar cell module can optionally be spread out as a surface element, for example in the arranged state on the assembled device. For example, the solar cell module can optionally be provided separately from the surface element as a wrap or as a compact one folded several times. For example, the solar cell module is designed as a multi-layer module.

For example, the solar cell module includes a thin-film solar cell, for example a silicon solar cell, comprising a photoelectrically active layer and a carrier layer. For example, the carrier layer provides mechanical stability of the solar cell module, e.g. B. a carrier layer component.

The solar cell module is z. B. with a solar cell layer component or with a photovoltaic layer component or a PV layer component, and a carrier layer, e.g. B. a carrier layer component, on or on which the solar cell layer component is applied, is formed.

For example, a side part of the zipper unit and/or a Velcro strip of the Velcro fastener unit is present on the backing layer, e.g. B. sewn, welded, fused and/or glued to the carrier layer. For example, an edge of the carrier layer protrudes beyond an edge of the solar cell or the thin-film solar cell, with a side part of the zipper unit and/or a Velcro strip of the Velcro fastener unit being present on the protruding edge. For example, the carrier layer consists of a film or a fabric material.

For example, the carrier layer and the solar cell layer component are designed to be flexible. For example, both the carrier layer and the solar cell layer component are connected to one another flatly or at points or in a line, e.g. B. glued.

The solar cell module is in particular a photovoltaic module. For example, the solar cell module is a thin layer element. For example, the solar cell module is z. B. a film layer element or a textile or film component or a film element, e.g. B. a film component. The solar cell part is on a carrier or the carrier layer such as. B. integrated or applied to a film.

For example, the solar cell module is a photovoltaic module, PV module e.g. B. designed as a photovoltaic film, as a PV film, PV film module or as a solar cell module.

For example, the solar cell module is flat with a surface side or top side which is used for light energy conversion and is directed outwards when the solar cell module is attached to the device.

For example, the solar cell module is releasably connected to the surface element via an edge region of the solar cell module by means of the zipper means. Alternatively or additionally, for example, the solar cell module is releasably connected to the surface element via an edge region of the solar cell module by means of the Velcro fastening means.

This is particularly practical for operating the zipper means or the Velcro fastener means. This solution also enables the solar cell module to be securely attached to the surface element. The type, positioning, number and/or dimensions of the zipper means or their zipper units and/or the Velcro fasteners or their Velcro fastener units are selected to suit this purpose. For example, these parameters depend on the size or dimensions, weight and/or shape of the solar cell module.

For example, exactly one solar cell module with exactly one zipper unit is provided on the device or on a surface element or a surface element section.

For example, exactly one solar cell module with exactly one Velcro fastener unit is provided on the device or on a surface element or a surface element section.

For example, the solar cell module is releasably connected to the surface element along two opposite edges of the solar cell module, e.g. B. linearly connected. For example, the solar cell module has an essentially polygonal or square like a rectangular floor plan. For example, the basic shape of the solar cell module has a square or rectangular outer contour.

For example, a side part of the zipper unit is z. B. permanently attached to the surface element. For example, a side part of the zipper unit is sewn, glued, welded or attached in one piece to the surface element. The same applies to attaching the other side part to the surface element.

For example, a Velcro fastener unit has two Velcro strips that can be releasably hooked together. The two Velcro strips include e.g. B. a Velcro strip with flexible loops, e.g. B. a fleece ribbon. The two Velcro strips include e.g. B. a Velcro strip with flexible barbs, e.g. B. a hook strap. For example, a Velcro strip of the Velcro fastener unit is z. B. permanently attached to the surface element. For example, a Velcro strip of the Velcro fastener unit is sewn, glued, welded or attached in one piece to the surface element. The same applies to the attachment of the other Velcro strip of the Velcro fastener unit to the surface element.

For example, alternatively, a side part of the zipper unit can be detached or separated non-destructively, e.g. B. attached to the surface element. The same applies to the attachment of the other side part to the surface element if it is not permanently attached.

According to a further example, a zipper unit has a slider and two elongated side parts that can be releasably hooked together, one side part of the zipper unit being present on the solar module and another side part of the associated zipper unit being present on the surface element. For example, the side panels include flat flexible bands, for example fabric bands.

For example, the zipper unit is a common zipper unit or a standard zipper unit. For example, the two side panels are thin and flexible. For example, the two side parts are designed as elongated and narrow parts that work together via the slide or can be separated and hooked together. For example, with the zipper unit, both side parts are present in such a way that the two side parts functionally provide the detachable arrangement of the solar module on the surface element in accordance with the function of the zipper means. A zipper unit includes the slider and the two elongated side parts that can be hooked together. For example, each side part has a plurality of regularly arranged hooking elements formed thereon. The hooking organs are, for example, tooth-like. With the slide, the hooking elements of one side part can be hooked together with the hooking elements of the other side part and can be detached from one another again. When the hooking elements are hooked, both side parts are firmly connected to each other.

It is, for example, such that the zipper means have two zipper units, each of which functions independently of one another, for a detachable arrangement of the solar cell module on the surface element. The two zipper units work e.g. B. separately. For example, exactly two zipper units or more than exactly two zipper units are each available separately from each other. For example, the two or more zipper units are all constructed identically. For example, exactly two zipper units have the same length. For example, the two or more zipper units differ from each other, e.g. B. in type and/or length.

For example, exactly one solar cell module is detachably connected to the surface element with exactly two zipper units. For example, exactly two or more than two zipper units are available separately from each other for each solar cell module and are each designed continuously. For example, a solar cell module is connected to the surface element by means of exactly two zipper units, which connect the solar cell module to the surface element in the area of opposite edges of the solar cell module.

A first zipper unit has a side part on a first edge of the solar cell module and the associated other side part of the zipper unit is present on the surface element.

A second zipper unit has a side part on a second edge of the solar cell module and the associated other side part of the zipper unit is present on the surface element.

Accordingly, the two side parts on the surface element are present at a distance corresponding to a distance between the associated side parts on the solar cell module.

For example, exactly one solar cell module is connected to exactly one surface element, e.g. B. connected to exactly one surface element section. For example, the surface element section is spatially fixed. For example, the surface element section has a strip-shaped film section that is next or uppermost in the direction of the ridge area. For example, the surface element section is a film section which has two opposite edges such as: B. Longitudinal edges are attached to a support of the surface element such as a support network. As a result, the section is essentially always spatially aligned in the same way, since the carrier and the film are spread out in a tensioned manner on the protective roof. For example, the carrier forms a tensioned underside of the surface element. For example, the carrier is stretched flat by z. B. tensioning devices such as tension wires. A spatial alignment of the attached solar cell module remains at least essentially preserved on the surface element or on the flat protective roof. This ensures optimal performance of the solar cell module for electricity generation, for example. B. guaranteed in windy conditions.

For example, a section of the surface element adjacent to the solar cell module has a film section which, for example, is fixed to the carrier with a longitudinal edge of the film section and at another edge such as. B. an opposite longitudinal edge of the film section is not connected to the carrier. This means that the adjacent section or the film section can be folded up on one side of the carrier, which is caused, for example, by wind or thermals.

An exemplary variant is characterized in that two zipper units are provided in such a way that a detachable arrangement of opposite edges of the solar cell module on the surface element is set up.

For example, there are exactly two zipper units for exactly one solar cell module. For example, if there are several solar cell modules on the surface element, exactly two zipper units are provided for each individual or for exactly one solar cell module. In the case of the two zipper units, the two zipper units are spatially spaced apart on the solar cell module and on the surface element. For example, the two zipper units work separately or independently of each other. Each individual zipper unit can be operated separately from other zipper units, such as: B. can be pulled up or closed or in the open, partially open or closed state.

For example, exactly one zipper unit and exactly one Velcro fastener unit are provided for detachably attaching the solar cell module to the surface element. For example, all other combinations of the number of zipper units and Velcro fastener units for attaching the solar cell module to the surface element are also possible.

A respective zipper unit is closed when both side parts are hooked together, which means that the solar cell module can generate or provide electrical energy when the protective roof is in operation. The actual basic function of the extended protective roof remains permanently and completely independent of the presence of the solar cell module. When the solar cell module is arranged on the surface element, electrical energy is provided when light is irradiated, for example for electrical consumers in the vicinity of the protective roof and/or for feeding electricity or electrical energy into an energy supply network or into an energy storage unit.

According to an example of the invention, it is such that the solar cell module is present in a region of the device which is adjacent to a ridge element of the ridge region.

For example, the solar cell module is present in a strip of the surface element that runs parallel to the ridge element, in this strip adjacent to the ridge element. For example, an edge of the solar cell module adjoins the ridge area or n. For example, an edge of the solar cell module adjoins the ridge area directly or is slightly offset from an upper end of the ridge area, for example offset downwards by 5 to 10 cm upper end of the ridge element.

For example, the ridge area extends in the longitudinal direction of the ridge element. For example, the ridge area is strip-shaped, for example 40 centimeters (cm) to 60 cm wide, for example 55 cm wide. For example, the ridge area has opposite longitudinal edges, with one longitudinal edge facing the ridge element, for example. B. extends along the ridge element z. B. extends parallel to the longitudinal axis of the ridge element.

For example, an area of a total area of the protective roof covered by the arranged solar cell module is between 5% and 100% of the total protective roof area. For example, a measure of coverage depends on the type of culture being covered.

The arranged solar cell module covers, for example, 70% to 100% of a total area of the ridge area.

For example, the solar cell module has a width of 15 to 60 cm, for example the solar cell module has a width of 30 to 55 cm, e.g. B. 35 cm, or a width of 55 cm.

For example, the surface element protrudes laterally from the respective longitudinal edge by 5 to 15 centimeters along a longitudinal edge or along both longitudinal edges of the solar cell module, i.e. on one or both sides.

For example, the surface element projects 10 centimeters beyond the longitudinal edges of the solar cell module on both sides.

A length of the solar cell module corresponds, for example, to a total length of the ridge area or the surface element present underneath or a total length of the ridge element.

For example, based on a total area of the protective roof spanned by the surface element of the protective roof, the proportion of the total area that is provided with the solar cell module is between 5 and 100% of the total area of the protective roof. For example, based on the total area of the protective roof spanned by the surface element of the protective roof, the proportion of the total area that is provided with the solar cell module is, for example, 10%, for example 20 percent, for example 30%, for example Example 40%, for example 50% or for example more than 50% of the total area of the protective roof.

The solar cell module includes exactly one connected component or includes several separate solar cell sub-modules such as. B. several identical or different solar cell sub-modules. This allows the individual solar cell sub-modules to be arranged in individually selectable or different areas of the surface element. For example, each solar cell sub-module is z. B. exactly one zipper unit or with exactly two zipper units on the surface element or with more than two zipper units releasably attachable or attached to the surface element.

According to an exemplary modification, a first zipper unit and a second zipper unit are provided, each with two side parts and a slider, a side part of the first zipper unit being present on the solar cell module along a first longitudinal edge of the solar cell module and where A side part of the second zipper unit is present on the solar cell module along a second longitudinal edge of the solar cell module. This allows a solar cell module to be arranged stably and securely on the surface element. A side part of the first zipper unit and a side part of the second zipper unit are correspondingly present on the surface element. On the surface element, the side parts are present in their orientation and distance from one another in accordance with the orientation and distance from one another as on the solar cell module.

According to an exemplary modification of the invention, the zipper means comprise a first zipper unit and a second zipper unit, each with two side parts, a side part of the first zipper unit being present on the surface element and the first zipper on the surface element spaced apart from the side part -Unit there is a side part of the second zipper unit. As standard, a zipper unit also includes a slider that opens and closes between the two side parts. For example, the side part of the first zipper unit and/or the side part of the second zipper unit is attached to the surface element by a joining method with a needle and thread or sewn on by one thread or by several threads. For example, a side part is attached to the surface element by an adhesive connection and/or a welded connection, for example. B. a thermoplastic or plastic welded connection. The attachment by gluing or welding can be done as an alternative or in addition to the attachment by a sewing-joining connection.

For example, the other side part of the first zipper unit is attached to a first edge, such as a first longitudinal edge of the solar cell module. For example, the other side part of the second zipper unit is attached to a second edge, such as a second longitudinal edge of the solar cell module.

An exemplary modification results in which the surface element has a first surface element section which is present adjacent to the ridge element and extends in the longitudinal direction of the ridge element, the surface element comprising a second surface element section which is present adjacent to the first surface element section, on a side of the first surface element section facing away from the ridge element, the solar cell module being present on an outside of the first surface element section.

This makes it possible to position the solar cell module at an advantageous or maximum height of the protective roof.

For example, the first surface element section extends in a strip shape, for example along a total length of the ridge area. For example, the first surface element section forms the ridge area, for example on both sides of a long side of the ridge element. For example, the first surface element section is inclined downwards from a side facing the ridge element to a side facing away from the deadline element or inclined to the horizontal. For example, a width of the first surface element section transverse to the longitudinal axis of the ridge element is between 40 and 70 centimeters. For example, a width of the first surface element section is 55 Centimeter. The second surface element section is a multiple of the width of the first surface element section.

For example, the second surface element section comprises several parallel strip-shaped sections, each made of a top-side film element such as. B. a film strip. For example, a film element or, for example, each film element is in each case along an upper longitudinal edge of the film element on a support of the surface element present underneath, such as. B. connected to a hail net, e.g. B. sewn on. For example, opposite front side edges and a lower longitudinal edge of the film element rest freely on the carrier.

For example, the carrier is present below the first surface element section and the second surface element section, for example of all the several film elements. The carrier, such as the hail net, is, for example, a uniform network element that is tensioned and spreads over the entire area. For example, the spatial orientation of the tensioned support specifies the inclination of the first surface element section and the second surface element section before or for all film elements.

As a rule, the second surface element section extends to an eaves-side or lower longitudinal edge of the surface element or of the protective roof that can be stretched with it.

For example, the surface element comprises an external film and a support underneath the film, such as a net element. For example, the film is a flexible, flat film component. For example, the film is closed flat or without holes or z. B. the film is not perforated. For example, the film is impermeable to rain, snow and wind. For example, the film is made of a plastic material. For example, the film is translucent or transparent or partially transparent to parts of the light or sunlight. For example, in the use state of the device, the film forms an outside of the surface element directed towards the atmosphere, such as a top side of the surface element, e.g. B. an outside of the protective roof.

For example, the carrier is regularly perforated with a large number of material-free openings or holes. For example, the carrier is a network element such as a textile flexible network element. For example, the network element is a hail protection net or a hail net and/or an insect protection net. For example, the net element is known from agricultural use, for example for hail protection or insect protection of fruit crops such as. B. cherry trees and the like.

Furthermore, another exemplary embodiment results if the solar cell module comprises a flexible carrier material to which a side part of a zipper unit is attached. For example, it is easily possible to sew the regular, for example flexible, side part onto the flexible carrier material of the solar cell module. For example, the carrier material of the solar cell module is a thin, bendable material. For example, the carrier material is a film material. For example, the carrier material is a flat material such as a flat film material, plastic material or a flat textile or fabric material.

For example, the PV unit or the photoelectrically active layer or the photovoltaically active layer of the solar cell module is present on the carrier material, e.g. B. attached or integrated.

For example, a side part of a zipper unit is sewn on, such as on the surface element or on a carrier material of the solar cell module. In existing manufacturing facilities and manufacturing processes for roofing systems with flexible surface elements, sewing devices are regularly used to connect or attach components. Such sewing devices can then also be used to produce the device according to the invention or a roofing system according to the invention.

For example, a zipper side part is sewn onto a film and/or a mesh fabric and the like.

For example, the side part of a zipper unit is sewn onto a film and onto a carrier material provided underneath in z. B. exactly one sewing process, for example at the same time the surface element can be connected to the carrier material and / or other parts of the device.

According to an exemplary design, the solar cell module comprises an electrical contact point, wherein the device has a line section which is fixed to a component of the device and is provided for electrically contacting the electrical contact point of the solar cell module. Such a line section includes, for example, an electrical cable. For example, a line section is held on an existing section of the device such as the support arrangement or on supports and/or a ridge element. For example The line section can be brought along these components from the outside to the contact point of the solar cell module. For example, an electrically conductive and electrically insulated connection between the contact point to a power storage or to an energy or electrical network is possible.

For example, holding means are present in such a way as to hold a region of the surface element in a storage position in order to temporarily arrange the region of the surface element in a non-covering arrangement in such a way that the region of the surface element in the storage position is folded or rolled up or gathered upwards in the direction of the ridge region and is held below a surface element section connected to the solar cell module, the area of the surface element being covered in the storage position by the surface element section connected to the solar cell module.

For example, the solar cell module can fulfill another function in the roofing system in addition to or as an alternative to generating electrical energy. For example in winter, e.g. B. if the roofing function of the protective roof is not set up, the area of the surface element that is provided with the solar cell module serves in the manner of a cover for the remaining surface element, if this is z. B. folded or compact and compressed below the surface element area with solar cell module is held with the holding means. The solar cell module then forms z. B. UV, temperature, rain and/or snow protection or other mechanical and chemical material protection for the surface element. At the same time, the advantageous energy generation function of the solar cell module for generating electrical energy from light energy is retained, even e.g. B. in winter or autumn. For example, the holding means include elongated elements such. B. elastic elements. For example, the holding means include a rubber band and/or a cable tie and/or a rope and/or a band and/or a wire and/or a film or net strip or the like.

According to an exemplary embodiment, the holding means comprise an elongated, flexible wrapping member, wherein the wrapping member can be arranged in a wrapping manner on the outside of the folded or rolled-up area of the surface element in the storage position. The wrapping element can be subjected to tension, for example. For example, the wrapping element has a hook element at one end, for hooking onto a hooking section, for example on a hooking section of the support arrangement or for example the ridge element or at the other end of the wrapping element. For example, the wrapping element is loop-shaped.

For example, the invention relates to a device for attachment to a roofing device, wherein the roofing device is used to roof an area outdoors, such as cultivation areas for cultivated or useful plants or areas used economically by others, wherein the roofing device comprises a surface element and a support arrangement with supports , and wherein the surface element carried by the support arrangement serves to form a flat protective roof above the area.

For example, the device has a solar cell module that is connected to a retrofit surface element, the device being designed as a retrofit arrangement for attaching the device to the roofing device in such a way that the retrofit surface element can be subsequently attached to the surface element of the roofing device is.

For example, exactly one solar cell module is attached to a coherent retrofit surface element. For example, several solar cell modules are attached to a coherent retrofit surface element, for example several identical solar cell modules.

For example, the retrofit surface element provided with the solar cell module is designed in such a way that it can be attached to exactly one side of the protective roof that is inclined obliquely from the ridge area. For example, the area with the solar cell module is present along a longitudinal axis of the retrofit surface element.

For example, the retrofit surface element provided with the solar cell module is designed such that it is present on both sides of the ridge area. For example, the retrofit surface element provided with the solar cell module is designed in such a way that it covers the ridge area and subsequent downward sections of the protective roof formed by the roofing device. The respective covered areas are each inclined, for example differently spatially inclined, for example at the same angle to the vertical. For example, on such a retrofit surface element, two spaced, parallel areas of the retrofit surface element are provided with a solar cell module. There is a gap between the two solar cell module areas. The distance covers the above when the device is attached roofing device the ridge area of the existing roofing device.

The solar cell module can therefore advantageously be attached to an existing roofing device, for example a conventional roofing device. The existing roofing device can advantageously be used permanently and/or temporarily to generate energy from sunlight.

For example, the retrofit surface element is subsequently attached to the surface element of the existing roofing device using attachment means, such as quick-release fasteners. For example, the attachment means include, for example, zipper means and/or Velcro fastening means and/or snap fastening means and/or adhesive means. For example, the retrofit surface element is subsequently attached to the surface element of the existing roofing device by sewing.

For example, the retrofit surface element is subsequently attached to the surface element of the existing roofing device using attachment means that are known or common in roofing such as roofing in agriculture and in the field of cultivating crops or crops. This is economically and technically advantageous, for example also advantageous in terms of handling. For example, the attachment means relate to those means which are used, for example. B. temporary or permanent attachment of the retrofit surface element to the surface element of the roofing device are formed.

For example, the retrofit surface element provided with the solar cell module is attached to a roofing device that is already in use, e.g. B. outdoors.

For example, the retrofit surface element provided with the solar cell module is attached to a top side or on top of an existing surface element or on a top side of a surface element of the existing roofing device. For example, the surface element of the existing roofing device is z. B. a film, a net, a hail net, a fabric and / or another flexible surface element.

For example, the retrofit panel is attachable to a panel of the existing roofing device, the panel being adjacent to a ridge area of the existing roofing device for roofing outdoor areas, e.g. B. cultivation areas for cultivated or useful plants or other commercially used areas, the support arrangement being anchorable to a floor surface of the area.

For example, when attached to the roofing device, the retrofit surface element extends from above to approximately 20 percent of the entire width or a height of a roof side of the protective roof of the roofing device. For example, a width of z. B. strip-shaped retrofit surface element 0.1 meter, 0.2 meter, 0.3 meter, or 0.4 meter to 0.6 meter for example 0.5 meter, based on the left or right side relative to a ridge element of the ridge area. For example, with a coherent design of the retrofit surface element across the ridge element and extending on both sides to the ridge area, the width of the retrofit surface element is z. B. 0.2 to 1.2 meters. For example, a predominant portion of the relevant surface side of the retrofit surface element is covered by the solar cell module. For example, 10% to over 90%, for example 70% to 90%, for example 80% of the relevant surface side of the retrofit surface element is covered by the solar cell module.

For example, the solar cell module is detachably and/or non-detachably attached to the retrofit surface element. The connection of the solar cell module to the retrofit surface element is detachable or non-detachable.

For example, the retrofit arrangement includes quick-release fastener means for attaching the solar cell module to the retrofit surface element, comprising zipper means with a Zipper unit and/or comprising Velcro fastening means and/or pressure fastening means.

For example, the solar cell module is sewn onto the retrofit surface element.

For example, the solar cell module is glued to the retrofit surface element.

For example, the solar cell module is connected to or on the retrofit surface element along its edges, for example along opposite longitudinal edges.

For example, the retrofit surface element can be detachably and/or permanently connected to the surface element of the roofing device.

For example, the retrofit surface element can be connected to the surface element of the roofing device using a plaque. For example, the plaque comprises two elements between which a section of the retrofit surface element and a section of the surface element of the roofing device are compressed and fixed. The two elements of the plaque are pressed against each other in order to connect the section of the retrofit surface element and the section of the surface element of the roofing device or the two layers of these surface elements lying one on top of the other between the two elements. For example, if the retrofit surface element is connected to the surface element of the roofing device using a plaque, the two elements of the plaque are pressed against one another and firmly connected to one another, for example releasably firmly connected to one another.

For example, when the retrofit panel is connected to the panel of the roofing device by means of a plaque, the two elements of the plaque are mutually locked, mutually locked, mutually hooked or locked together or otherwise fixed to one another.

The sections of the retrofit surface element and the surface element of the roofing device can be connected to one another additionally or exclusively using screw closure means.
