    Frame of a module for a modular photovoltaic system, module manufactured with it and
    modular photovoltaic system
    The invention relates to a frame of a module for a modular photovoltaic system, according to the preamble of claim 1. The invention further relates to a module for a modular photovoltaic system with a frame and a functional element arranged in the frame. The invention finally relates to a modular photovoltaic system that
    can be assembled from a large number of photovoltaic modules.
    Roof surfaces of residential buildings are particularly suitable for the installation of solar energy systems, whereby the solar energy systems are designed either to convert solar energy into thermal energy by means of thermal solar elements or to convert solar energy by means of photovoltaic modules. In the case of a modular design of the solar energy systems as photovoltaic systems, individual photovoltaic modules are generally combined on the roof surface to form a photovoltaic system, with such photovoltaic systems being able to be mounted both on flat roofs and on sloping roof surfaces. The photovoltaic system can be set up either as a roof-top system or as an in-roof system, particularly with sloping roof surfaces
    become.
    While the photovoltaic system in roof-top systems is mounted on a substructure that is attached to the roof, in roof-top systems the individual modules of the
    Photovoltaic system integrated into the roof.
    In this case, in-roof systems have the advantage over roof-top systems that roof material is saved when they are erected, whereby the costs for the roof covering can be significantly reduced. In addition, photovoltaic in-roof systems are aesthetically more appealing compared to photovoltaic roof-top systems, as they do not require a conspicuous substructure on which the photovoltaic system is mounted, but replace at least part of the roof covering and thus blend in harmoniously with the
    Insert the overall appearance of the roof. In the case of mounting systems for photovoltaic in-roof systems, the individual modules
    usually in several superimposed, horizontally running rows
    arranged, with the rows overlapping each other from the roof ridge to the eaves.
    to form a connection between the adjacent panels.
    From a further patent application US 2014/0069482 solar roof tiles are known which comprise a substrate and a solar module applied to the substrate, the solar roof tiles having arcuate cover sides which are designed for the purpose
    Contact the cover side of the neighboring solar roof tile.
    Systems currently available on the market for photovoltaic in-roof systems, however, have the
    The disadvantage is that their assembly is very complex. There are several reasons for this.
    On the one hand, with the assembly systems available to date, it is necessary to tightly connect the individual modules arranged next to one another using additional connecting elements such as profile rails or potting material in order to prevent water from collecting between the individual modules by allowing the water to drain off. However, the use of these additional connecting elements results in additional effort when installing the photovoltaic
    In-roof system.
    On the other hand, in previously available systems with overlapping modules, the joints between the photovoltaic modules have to be laboriously sealed in order to prevent water from penetrating, in particular to the sensitive electrical and electronic ones
    Components of the modules, to prevent.
    Conventional photovoltaic modules have the disadvantage of complex production or
    often consist of a multitude of different components, which is due to itself
    Manufacturing methods such as deep drawing are used.
    Profile elements for fastening photovoltaic modules are known from CH 708 859 A2. A first profile element is designed in the form of a hollow profile which is open on both sides and which has at least one support area and a channel at a first end and a fastening groove at a second end. A second profile element for fastening photovoltaic modules is designed in the form of a hollow profile open on both sides, which has at least one support area and a cover element at a first end, the cover element having an engagement leg on its side facing the second end of the hollow profile. In addition, elaborately designed corner modules are provided, which are required to connect the profile elements and to prevent rainwater from entering. A solar system comprises several first profile elements, a second profile element and a photovoltaic module which rests on the support areas of the first profile elements and the second profile element and is glued to them. An in-roof or on-roof solar system arrangement comprises several solar systems, the engagement leg of the second profile element of a first solar system engaging the channel of a first profile element of a second solar system and this first profile element being arranged on the side of the second solar system opposite the second profile element. The disadvantage of this system is the large number of different components that make up the solar system, as well as the complexity of these components. Even the assembly of such a complicated one
    Solar systems on house roofs are difficult.
    Therefore, there is still a need for systems made up of modular photovoltaic modules and photovoltaic modules based on a frame, which can be manufactured and installed easily and cost-effectively. Another requirement for a photovoltaic module system is that the modules can be arranged next to each other in one level on the roof in order to keep the structure on the roof as low as possible and to be able to meet architectural requirements and the disadvantages of the assembly of conventional modular photovoltaic systems, their modules each other
    To be able to cover over roof tiles like to avoid. The present invention achieves the stated objectives by providing a frame
    a module for a modular photovoltaic system with the features of claim 1,
    a module for a modular photovoltaic system with a frame according to the invention
    the dependent claims, the following description and the drawings.
    The frame according to the invention of a module for a modular photovoltaic system is composed of a first and a second opposing frame longitudinal elements and a first and a second opposing frame transverse elements, the frame transverse elements being connected to the frame longitudinal elements. The frame longitudinal elements and the frame transverse elements are designed as extruded profiles or rolled profiles. A longitudinal overlap fold extends from the top of the first frame longitudinal member away from the frame, and a transverse overlap fold extends from the top of the first frame cross member away from the frame. The longitudinal cover fold has a first longitudinal cover fold end region and a second longitudinal cover fold end region, the transverse cover fold having a first transverse cover fold end region and a second transverse cover fold end region, the first longitudinal cover fold end region and the first transverse cover fold end region and the second longitudinal end fold region being free-standing and the second longitudinal end fold region the second transverse overlap rebate end area are connected to one another to form a common overlap rebate end area, wherein - measured from a support surface of the frame, d. H. from the underside of the frame - the underside of the longitudinal overlap rebate is at least as high as the upper side of the second longitudinal frame element and the underside of the transverse overlap rebate is at least as high as the upper side of the second frame transverse element. The frame according to the invention is characterized in that the underside of the free-standing transverse overlap rebate end area is at least as high as the upper side of the free-standing longitudinal overlap end area and the underside of the common corner area of the overlap rebate is at least as high as the upper side
    of the free-standing transverse overlap fold end area.
    It should be noted that the terms “longitudinal” and “transverse”, as used in this document, are only to be understood as geometrical definitions and not as dimensions. This means that, for example, the longitudinal frame elements can be of the same length or shorter than the transverse frame elements. In general, the frame will be rectangular or square, but different geometries can be provided for certain applications, e.g. diamond-shaped
    or parallelogram.
    By forming the frame elements from extruded profiles, the frame is particularly easy to manufacture, for example by cutting the extruded profiles to the required lengths and connecting them using appropriate connecting means such as screws or angles, or by soldering or gluing. As an alternative to extruded profiles, the frames can also be made from rolled profiles
    be.
    For a large number of applications and for simple assembly, it is preferred if the longitudinal overlap rebate extends over the entire length of the first longitudinal frame element and the transverse overlap rebate extends over the entire length of the first frame transverse element, the longitudinal overlap rebate and the transverse overlap rebate being connected to one another in the common corner area . The connection of the longitudinal overlap rebate and the transverse overlap rebate in the common corner area can be done, for example, by soldering, gluing, crimping, etc. Furthermore, the longitudinal overlap rebate and the transverse overlap rebate can be butt-to-butt, in particular miter-cut, or in the common corner area
    be arranged overlapping each other.
    To improve the prevention of water penetration between adjacent modules based on the frame according to the invention, one embodiment of the invention provides that seals are arranged on the upper side of the first or second longitudinal frame element or on the underside of the longitudinal overlap rebate and / or that on the upper side of the first or second frame cross element or on the underside
    the transverse overlap seals are arranged.
    The improved sealing is also used if at least one groove and / or at least one web extends on the upper side of the second longitudinal frame element over its length and webs and / or webs which are opposite to the grooves or webs of the second longitudinal frame element extend on the underside of the longitudinal overlap over its length. or grooves extend. As an alternative or in addition to this, it can be provided that the
    Upper side of the second frame transverse element over its length at least one groove and / or
    Extending webs and / or grooves.
    For the production of the frame elements on an industrial scale, it is advantageous if the longitudinal overlap rebate is formed in one piece with the first frame longitudinal element and / or the transverse overlap rebate is formed in one piece with the first frame transverse element
    is trained.
    In practice, a photovoltaic system according to the invention is composed of a large number of modules based on the frame according to the invention, which are arranged in several rows adjacent to one another, i.e. in a matrix of columns and rows. As with roofing, the modules are laid from bottom to top by first laying the first (bottom) row from right to left, whereupon the second row is made again from right to left, and so on up to the top row. If the longitudinal overlap folds of the frame are on the opposite side of the
    Frames are located, the rows are laid from left to right.
    In order to be able to reliably connect adjacent frames of a column by plugging them together in a few simple steps, one embodiment of the invention provides that a projection is formed in the outer wall of one of the two frame transverse elements and a recess or a hole is formed in the outer wall of the other of the two frame transverse elements is formed, wherein the projection of one frame cross element of the recess or the hole of the other frame cross element is opposite and the recess or the hole is at least as large
    is dimensioned like the projection.
    In order to join modules in a row, it is further provided that a projection is formed in the outer wall of one of the two frame longitudinal elements and a recess or a hole is arranged in the outer wall of the other of the two frame longitudinal elements, the projection of one frame longitudinal element of the recess or the Opposite hole of the other longitudinal frame element and the recess or the hole is at least as large as the projection. However, it should be noted that the modules in a row cannot simply be pushed onto the frames of the adjacent column in the same row if the adjacent longitudinal frame element is provided with webs on its surface or the frame to be pushed on is provided on the underside
    its longitudinal overlap is provided with webs. So that joining in
    71728
    running movement are joined together.
    One aspect of the frame according to the invention is that the undersides of the frame longitudinal elements and the frame transverse elements lie in a common plane which forms a support surface.
    In order to arrange adjacent frames side by side in a high packing density, the outer side walls of the frame longitudinal elements and the frame transverse elements for a
    Side-by-side arrangement of multiple frames can be formed.
    Because of their strength, their low price and the possibility of industrial production, it is preferred if the frame longitudinal elements and the frame transverse elements are made from
    Aluminum or a, preferably fiber-reinforced, plastic.
    In a preferred embodiment of the frame according to the invention, a cutout is formed in the free-standing first end region of the longitudinal overlap fold. If several frames are arranged side by side, this cutout serves to protect the interconnected frames against upward flowing water, which occurs in strong winds
    cover with rain can occur.
    In order to be able to compensate for material expansions of the frames due to strong temperature fluctuations, which inevitably occur on roofs, distances are provided between subregions of the frames. So that such distances for material expansion on the frame can be moved inward to a seal, it is advantageous if in
    free-standing first end region of the transverse overlap fold a cutout is formed.
    A module according to the invention for a modular photovoltaic system comprises a frame according to one of the embodiments described above and at least one functional element arranged in the frame, the frame having a holder to which the functional element is fastened in a sealing manner. According to a preferred embodiment, the holder is formed from webs, as a U-profile, as a tubular profile or as a flat sealing surface in which the functional element is received. The
    Functional element can on the one hand be a photovoltaic element, but it can also
    significantly reduced.
    A modular photovoltaic system according to the invention can be assembled from a multiplicity of modules explained above, at least one of the modules having a functional element in the form of a photovoltaic element. Thus, the photovoltaic system can save at least part of a roof covering or the entire roof covering by forming at least a part of the roof or the entire roof from the modules designed in this way, the modules being a combination of photovoltaic elements, decorative elements, cover plates, ventilation elements , Elements with a passage, window elements, verge elements and / or a roof ridge elements can represent, which allows great flexibility in the design of the roof surface. The photovoltaic system according to the invention can be excellently integrated into a roof covering in that the modules can be arranged side-by-side and the undersides of the frames of the modules form a support surface that rests in one plane on a roof substructure. This avoids the conventional "roof tile arrangement" of modules, in which a module is partially above the
    other lies.

    Reference is first made to FIGS. 1-10, which show a frame 1 according to the invention of a module for a modular photovoltaic system in various views and sections. The frame 1 is composed of a first and a second opposing frame longitudinal elements 2, 3 and a first and a second opposing frame transverse elements 4, 5. The frame transverse elements 4, 5 are connected to the frame longitudinal elements 2, 3 at their ends, so that they form a rectangle. The longitudinal frame elements 2, 3 and the transverse frame elements 4, 5 are designed as extruded profiles, in particular made of aluminum or a preferably fiber-reinforced plastic. Each extruded profile has - seen in cross section - a hollow body 6, in this embodiment a rectangular hollow body 6, which gives the frame transverse elements 4, 5 and the frame longitudinal elements 2, 3 rigidity against bending and twisting. From the hollow body 6, webs 7, 8 extending inwardly extend from its upper side and near its upper side over the length of the longitudinal frame elements 2, 3 and the transverse frame elements 4, 5. These webs 7, 8 serve to hold functional elements in a sealed manner, in particular photovoltaic elements, but also functional elements that consist of
    Cover plates, decorative elements, ventilation elements, elements with at least one
    Passage, window elements, verge elements and / or roof ridge elements are selected. From the underside of the hollow body 6 of the extruded profile, webs 9 extend inward over the length of the frame longitudinal elements 2, 3 and the frame transverse elements 4, 5, which together with the underside of the hollow body of the extruded profile form a support surface 10 of the frame 1. The outer side walls 2a, 3a, 4a, 5a of the frame longitudinal elements 2, 3 and the frame transverse elements 4, 5 are for a side-by-side
    Arrangement of several frames 1 formed.
    From the upper side 2d of the first longitudinal frame element 2, a longitudinal overlap rebate 22 extends away from the frame 1 outwards over the length of the first longitudinal frame element 2. The longitudinal overlap rebate 22 has a first longitudinal overlap rebate end area 22a and a second longitudinal overlap rebate end area 22b. From the upper side 4d of the first frame transverse element 4, a transverse overlap fold 42 extends outwardly away from the frame 1. The transverse cover fold 42 has a first transverse cover fold end region 42a and a second transverse cover fold end region 42b. The first longitudinal overlap fold end region 22a and the first transverse overlap fold end region 42a are designed to be free-standing. The second longitudinal overlap rebate end area 22b and the second transverse overlap rebate end area 42b are connected to one another to form a common overlap rebate end area 11, with - measured from the support surface 10 - the underside 22c of the longitudinal overlap rebate 22 is at least as high as the upper side 3d of the second longitudinal frame element 3 and the underside 42c of the transverse overlap fold 42 is at least as high as the top 5d of the second frame cross element 5. The underside 42f of the free-standing first transverse overlap end region 42a is at least as high as the top of the free-standing first longitudinal overlap end region 22a. The underside 11a of the common overlap rebate corner area 11 is at least as high as the upper side 42e of the free-standing first transverse overlap rebate end area 42a. The longitudinal overlap rebate 22 is preferably formed in one piece with the first longitudinal frame element 2. The transverse overlap fold 42 is also preferably formed in one piece with the first frame transverse element 4. Fastening screws 50 are shown in the figures as a dash-dotted line. The position of the fastening screws 50 in the frame 1 is such that, in the installed position, they are covered by the transverse overlap rebate 42 and the longitudinal overlap rebate 22 of adjacent frames 1 and are not visible. This offers advantages for tightness, optics and costs of the photovoltaic system, since none
    Sealing washers must be used.
    The connection of the second longitudinal overlap rebate end area 22b and the second transverse overlap rebate end area 42b to the common overlap rebate end area 11 can take place by soldering, gluing, crimping, etc. For this purpose, either the second longitudinal overlap rebate end area 22b and the second transverse overlap rebate end area 42b can be cut off, e.g. mitred, so that the cut edges of these end areas 22b, 42b lie side by side and are tightly connected to one another by gluing, soldering, etc. Or the second longitudinal overlap fold end region 22b and the second transverse overlap fold end region 42b are superposed
    arranged and connected to each other.
    For a high sealing effect, seals 12, 13 can be arranged on the upper side of the first or second longitudinal frame element 2, 3 or on the underside of the longitudinal overlap fold 22. Similarly, on the top of the first or second frame cross element 4, 5 or on the underside of the transverse overlap fold
    42 seals 14 may be arranged.
    In order to seal adjacent frames 1 against the ingress of water, two webs 3c are formed on the upper side 3d of the second longitudinal frame element 3 running over its length, and grooves which are opposite to the webs 3c of the second longitudinal frame element 3 extend on the lower side 22c of the longitudinal overlap fold 22 over its length 22d. When the adjacent frames 1 are connected, the webs 3c engage in the grooves 22d and thereby form, on the one hand, a labyrinth passage through which wind-driven water cannot flow. On the other hand, the grooves 22d form drains for the few
    Water that may have entered this labyrinth passage.
    It is provided that adjacent frames 1 can be connected to one another in the form of a matrix of columns and rows, the connection preferably being made by plugging the frames 1 together from right to left and from bottom to top. This means that the first (bottom) row is laid from right to left, after which the second row is made again from right to left, and so on up to the top row. For this purpose, two projections 2b in the form of pins are formed in the outer side wall 2a of the first longitudinal frame element 2 and holes 3b are formed in the outer side wall 3a of the second longitudinal frame element 3. The projections 2b of the first longitudinal frame element 2 are opposite the holes 3b of the second longitudinal frame element 3, and the holes 3b are at least as large as the projections 2b. So that the adjacent frame 1 also then in one
    Sliding movement can be joined together when at the top 3d of the second
    Frame longitudinal element webs 3c are and if there are grooves 22d on the underside 22c of the longitudinal overlap rebate 22, provision is made for the holes 3b to be designed as curved and / or oblique elongated holes, the height difference x at the beginning and at the end of the elongated hole being at least as large as the Height of the webs 3c or the grooves 22d (see FIG. 15). In Fig. 10 the hole 3b is exemplified as an elongated hole with a kink. This embodiment is the preferred embodiment. Preferably, the pin-shaped projection 2b tapers towards its free end in order to
    To facilitate insertion of the protrusion 2b into the hole 3b.
    In order to plug the frames 1 together in a column of the matrix arrangement, a projection 4b in the form of a pin is formed in the outer side wall 4a of the first frame transverse element 4. Furthermore, a hole 5b is formed in the outer wall 5a of the second frame cross member 5. The projection 4b of the first frame transverse element 4 lies opposite the hole 5b of the second frame transverse element 5. The hole 5b is at least that big
    dimensioned like the projection 4b.
    In order to prevent water flowing upwards from entering the corner at the common corner of four joined frames 1, a cutout 22f is formed in the free-standing first end region 22a of the longitudinal overlap fold 22. Furthermore, a cutout 42g is formed in the free-standing first end region 42a of the transverse overlap fold 42, as a result of which a spacing y (see FIG. 13) to be provided for material expansion of the
    Frame 1 can be shifted inwards.
    The features of the frame 1 allow frames 1 to be connected to one another side by side in a matrix arrangement in a support surface 10, it being ensured that no water penetrates between the frames 1. The concept of the frame 1 is based on the fact that the four corner areas of the frame 1 have different heights, so that when four frames 1 are joined together in two columns and two rows, the adjacent frames 1 overlap each other in the common corner area of these four frames in four different levels. The lowest level, which represents a reference plane, is formed by the top side 3d of the second longitudinal frame element 3 and the top side 5d of the second frame transverse element 5, the common corner area of the second frame longitudinal element 3 and the second frame transverse element 5 being particularly relevant. The second level is defined by the free-standing first longitudinal overlap fold end region 22a, which is higher than the top side 3d, 5d of the second longitudinal frame element 3 and of the second transverse frame element 5. Above this second
    The third level is the free-standing first transverse overlapping fold end region 42a
    intended. The fourth level, which is the highest level, is formed by the common overlap fold end region 11. The different levels can go through
    Offset of the corresponding parts or sections of the frame 1 can be realized.
    A modular photovoltaic system 100 according to the invention with modules 60, 70, 80, 90 each comprising a frame 1 and functional elements 61, 71, 81, 91 is explained below with reference to FIGS , 70, 80, 90 to clarify by means of their frame 1. To the extent that frame parts are shown in FIGS. 12 to 16 and provided with reference symbols, reference is also made to the illustrations in FIGS. 1 to 11 and, in order to avoid repetition, reference is made to the above explanations of these frame parts, the same reference symbols denoting the same parts. The functional elements 61, 71, 81, 91 of the modules 60, 70, 80, 90 are fastened in brackets which consist of the inside webs 7, 8 of the frame 1. Together with the hollow body 6 of the extruded profile from which the frames 1 are made, this results in a U-profile that encloses the edges of the functional elements 61, 71, 81, 91. The functional elements 61, 71, 81, 91 are on the one hand photovoltaic elements, but on the other hand can also be selected from a cover plate, a decorative element, a ventilation element, an element with at least one passage, a window element, a verge element and / or a roof ridge element
    be.
    The modular photovoltaic system 100 shown by way of example in FIGS. 12 to 16 comprises four modules 60, 70, 80, 90. The photovoltaic system 100 is assembled by first placing and mounting the first module 60 on a substrate, such as a roof substructure. Next, the second module 70 is arranged above the first module 60, so that the second frame cross element 5 of the first module 60 and the first frame cross element 4 of the second module 70 lie side by side and the transverse overlap fold 42 of the second module 70 the second frame cross element 5 of the first module 60 covered. For a secure connection, the projection 4b, designed as a pin, of the first frame transverse element 4 of the second module 70 engages in the hole 5b of the second frame transverse element 5 of the first module 60. Next, the third module 80 is inserted into the photovoltaic system 100 by arranging it next to the first module 60 (to the left of the first module 60 in FIG. 12) so that the second longitudinal frame element 3 of the first module 60 is side by side next to the first Frame longitudinal element 2 of the third module 80 lies and the projections 2b (pins) of the outer side wall 2a of the first frame longitudinal element 2 of the third module 80 into the
    Elongated holes 3b engage in the outer side wall 3a of the second longitudinal frame element 3
    and the longitudinal overlap fold 22 of the third module 80 covers the second longitudinal frame element 3 of the first module 60. Then the third module 80 is moved down into its end position, in which the webs 3c on the upper side 3d of the second longitudinal frame element 3 of the first module 60 engage in the grooves 22d formed on the lower side 22c of the longitudinal overlap fold 22 of the third module 80. Finally, the fourth module 90 is arranged next to the second module 70 and above the third module 80 and, similarly as described above for the second and third modules 70, 80, shifted so that in its end position the longitudinal overlap fold 22 of the fourth module 90 is the second Longitudinal frame element 3 of the second module 70 covers and the transverse overlap fold 42 of the fourth module 90 covers the second transverse frame element 5 of the third module 70. As can best be seen in FIGS. 13 and 15, in the common corner area of the four modules 60, 70, 80, 90 sections of all four modules 60, 70, 80, 90 lie one above the other. Due to the design of the frame 1, however, this common corner area of the four modules 60, 70, 80 90 is also tight against the ingress of water. 13 shows the module 60 at the bottom (on the left in the drawing). Its second longitudinal frame element 3 and the outer side wall 3a of the second longitudinal frame element 3 as well as the webs 3c located on the upper side 3d of the second longitudinal frame element 3 can be seen. Module 80 is arranged to the right of module 60. Its first longitudinal frame element 2 can be seen with its outer side wall 2a and the longitudinal overlap fold 22 with grooves 22d on its underside 22c. The longitudinal overlap fold 22 of the module 80 covers the frame longitudinal element 3 of the module 60. On the left-hand side of FIG. 13, the transverse overlap fold 42 of the module 70 can be seen, the free-standing first transverse overlap fold end region 42a of which covers the longitudinal overlap fold 22 of the module 80. On the right-hand side of FIG. 13, the common overlapping fold end region 11 of the module 90 can be seen, which covers the free-standing first transverse overlapping fold end region 42a of the module 70. Distances for material expansion are indicated by the arrows y. Modular photovoltaic systems 100 of any size can be assembled in the manner described above. It is also essential in this photovoltaic system 100 that the modules 60, 70, 80, 90 can be arranged side-by-side and the undersides of the frames 1 of the modules 60, 70, 80, 90 form a support surface 10 on a roof substructure. In contrast to the state of the art, a “roof tile arrangement”, where a module with its underside is partially on
    the other should be avoided.
