Definitions
- the invention generally relates to a device for attaching and holding solar modules.
- the present invention relates in particular to a load-bearing backrail for a frameless multilayer solar module for insertion into a carrier system and a backrail adapter adapted to standard backrails to insert a solar module with standard backrails in a carrier system can.
- the invention further relates to a solar module with a backrail according to the invention or with a standard backrail, which in turn is connected to a backrail adapter according to the invention.
- the present invention relates to a solar system with a plurality of the aforementioned solar modules. Due to increased environmental awareness and rising costs of conventional energy sources, the demand for renewable energy sources is constantly increasing. Great efforts are being made to produce low-cost solar modules.
- solar modules are manufactured in a planar and rectangular configuration.
- the solar modules can be manufactured with a surrounding frame or frameless. Around the outer edges of the frame or the frameless solar module then around the outer edges embracing brackets are attached directly to the outer edges in order to fix the solar module on or in a support structure can.
- Such fasteners must be designed so that high loads (e.g., by snow) and high suction forces (e.g., caused by wind) can be safely transferred from the solar module to the support system without damaging the solar module.
- the outer edges are particularly vulnerable, since there sit the force-transmitted brackets.
- a further problem is that some solar module manufacturers connect their (in particular frameless) solar modules on the rear side with a "standardized" or uniformly predefined retaining rail
- the standardized support rails are attached along one longitudinal side of the (rectangular) solar module to the same and terminate shortly before the outer edges of the solar module.
- the distance of the standardized support rails hereinafter referred to as "standard backrails" 50 mm, whereby the distance between the longitudinal ends of the backrail and the adjacent outer edge is actually standardized.
- Typical forms of standard backrails are shown in US patent application US 2009/0205703 AI.
- Fig. 2A of US 2009/0205703 AI a V-shaped standard backrail is shown, which is shown in FIG. 7 with a Distance D of approximately 50 to 300 mm from the adjacent outer edge is removed.
- Fig. 3 W-shaped standard backrails are shown.
- Solar modules that are equipped with standard backrails are not suitable for use in an insertion system for (frameless) photovoltaic or solar modules due to the distance of the standard backrails to the respective adjacent outer edges.
- Such insertion systems as exemplified by the mounting system AluTec 42 FL Creotecc company, require a backrail, which extends over the entire length of the back of the solar module, i. extends from an outer edge to the opposite outer edge. Solar modules with standard backrails are therefore not suitable for installation in insert systems.
- a load-bearing backrail for a frameless multilayer solar module for insertion into a carrier system, the solar module having a front and a back, each preferably made of glass, between which an energy-generating layer is embedded; wherein the backrail has an elongated main body whose geometric Length in its longitudinal direction corresponds to a geometric length of the rear side of the solar module from an outer edge to an opposite outer edge of the solar module, between which the main body, preferably by means of an adhesive, attached to the back of the solar module; wherein the backrail further comprises at least one nose member which adjoins one of the longitudinal ends of the main body in the longitudinal direction and which, when the backrail is attached to the solar module, extends without contact around one of the outer edges of the solar module; and wherein the nose member has a first portion extending longitudinally and a second portion connected to the first portion that extends non-contactly along the one outer edge such that the second portion projects beyond the front of the solar module in a height direction.
- the length of the backrail is thus selected such that the solar module can be inserted without additional adapter in the carrier system.
- the nose element is spaced longitudinally relative to the outer edge of the solar module. The nose element protrudes beyond the front of the solar module, so that can be completely dispensed with the edge protection elements required in the prior art, which had embraced the outer edges. Since the nose element is connected to the backrail, a power transmission takes place from the backrail into the nose element, and then from the nose element into a carrier profile. Typically, the carrier profile abuts the outside of the second portion of the nose member, due to gravity, which is usually caused by the inclined placement of the carrier system.
- the lifting forces are transferred from the solar module to the backrail. From the backrail the lifting forces are transferred to the nose element. And from the second portion of the nose element, the lifting forces are introduced into the carrier profile surrounding the nose element. The forces thus follow a path through the solar module, which spares the outer region, and in particular the outer edges of the solar module. Since the outer edge regions of the solar module, in particular the laminate layers (glass, photovoltaic layers, glass), neither with the carrier profile (edge protection elements missing) nor with the backrail in combination, the sensitive outer edges remain almost free of forces.
- solar modules that are connected to a backrail according to the invention, easier to install in an insertion system.
- the previously required edge protection elements can be omitted.
- the nose element allows a slip-off, for example, in the case of failure or destruction of the connection (bonding) between the backrail and the solar module.
- the compound can be adversely affected by environmental influences (moisture, expansion and shrinkage due to heat, etc.).
- a further advantage is that the backrails according to the invention can be mounted on the manufacturer side like standard backrails on conventional solar modules, i. E. in the outer edge area no connection between the backrail and the back of the solar module is made by, for example, there the bonding is omitted, so that existing certifications of solar modules can be used with standard backrails.
- Each module manufacturer makes installation specifications for certification of its modules and releases other mounting solutions most likely, if they meet these requirements. A release is therefore unlikely to be granted if deviations from the standard conditions (e.g., Backrail may only extend to a maximum of 50mm from the edge of the module).
- first portion and the second portion are substantially at right angles to each other.
- This geometry is adapted to the usual geometry of the solar module in the region of the outer edges. It is understood that with different geometries of the outer edges of the first and second portions can be arranged and formed accordingly.
- a third section adjoins the second section, which is oriented parallel to the front and which is designed such that the front of the solar module is encompassed without contact.
- the third section is used for a further mechanical protection of the solar module before excavation, should the connection between the backrail and the solar module unexpectedly solve.
- each nose element on a material and a material thickness, which are suitable, the solar module should the solar module detach from the backrail to secure in the longitudinal direction against slipping.
- a load-bearing backrail adapter for use with a standard backrail, which is attached to a back of a frameless multilayer solar module, preferably by gluing, wherein the solar module with an underside of the standard Backrails is preferably inserted into a cross-composite support system with vertical support rails, wherein an elongated main body of the standard backrail each extending with a manufacturer side predetermined distance from an outer edge of the solar module to an opposite outer edge of the solar module, wherein the adapter comprises: an extension element with one of the longitudinal ends of the main body is coupled such that the extension element extends the main body at least with its bottom substantially up to the one outer edge of the solar module, which is the one longitudinal end of the standard Opposite backrails; and a nose member which adjoins the extension member in the longitudinal direction; wherein the nose member has a first portion extending contactlessly along the back side of the solar module beyond one outer edge in the longitudinal direction, and a second portion connected to the first portion and
- the adapter further includes a coupling member that, in a condition when the adapter is coupled to the standard backrail, extends from the extension member into the standard backrail and / or around the standard backrail extends.
- the coupling element is shaped such that it engages positively in and / or around the standard backrail.
- a form fit alone may already be sufficient to connect the adapter with the standard backrail so that the loads acting on the solar module can be safely transferred to the surrounding carrier system.
- the coupling element touches the back of the solar module, in particular flat, when the coupling element engages positively in the backrail.
- the adapter has a collar in a transition region between the extension element and the coupling element, which projects beyond the standard backrail in such a way that the coupling element engages only up to the collar in and / or around the backrail.
- the collar then constitutes a stop, so that the adapter does not engage beyond a predetermined depth in the standard backrail.
- the adapter is made of an electrically non-conductive material, preferably made of plastic.

- the main body 12 has a bottom 14, which merges into laterally widening support walls 16 and 18.
- the support walls 16 and 18 are arranged here in a V-shape and have a certain flexibility for absorbing forces, in particular bending forces.
- the support walls 16 and 18 merge into wing-like attachment sides 20 and 22 which extend substantially in a horizontal plane as well as the bottom 14.
- the support walls 16 and 18 extend substantially in a vertical plane.
- the upper surfaces of the attachment sides 20 and 22 represent adhesive surfaces 24, for example, which - in an assembled state of the solar module - are oriented parallel to a lower side of the solar module.
- V-shape shown in FIG. 1 can be modified.
- a W-shape, T-shape, Z-shape, or the like could be used.
- an internal cavity mold e.g., square tube or the like
- the shape should be chosen so that the back rail 10 is strong enough to support the solar panel under allowable loads, yet flexible enough to minimize the maximum voltage exposed to the solar panel during normal operation and normal environmental conditions.
- the main body 12 can be attached to the solar module, for example, by means of a strong, flexible adhesive or a double-sided adhesive tape, which in turn withstand the environmental influences.
- the main body 12 of the backrail 10 may be made of, for example, extruded aluminum, formed sheet or cold rolled steel. Other materials with similar strengths and flexing properties can be used as well.
- the main body 12 of the backrail 10 may be coated with a suitable anti-corrosion coating.
- the main body 12 could be coated with an aluminum-zinc coating containing, for example, 55 wt% aluminum and 45 wt% zinc.
- the nominal coating thickness may be, for example, 15 pm to 30 pm on each side of the main body 12.
- the main body 12 may also be made of galvanized steel.
- the main body 12 could also be made of a plastic or a cardboard material.
- the above-mentioned adhesives must be sufficiently strong to withstand stresses caused by, for example, wind in the form of suction effects. In addition, the adhesive must be sufficiently flexible to allow the backrail 10 to expand or contract slightly with respect to the module during extreme temperature variations.
- an adhesive surface 26 adjoins the adhesive surfaces 24 in the longitudinal direction L, where the main body 12 merges into so-called nose elements 28, which extend essentially in a height direction H.
- the free surfaces 26 and the nose elements 28 are arranged in the region of longitudinal ends 30 and 32 of the main body 12. On the specific design and arrangement of the nose elements 28 will be discussed in more detail below.
- a conventional solar module 40 ( Figures 2 and 4) connected to a conventional backrail 10 'is shown at its rear 42.
- FIG. 2 one looks at the underside 42, which is shown partially transparent, to reveal a view of a photovoltaic layer of the solar module 40.
- a connection element 44 is provided for the electrical connection of the photovoltaic layer to an external energy store or consumer or to a current transformer or network.
- Edge protection elements 46 are arranged around the outer edge of the solar module 40.
- FIG. 3 is a longitudinal end of the conventional backrail 10 ', which is provided with a galvanic separation element 48 to prevent electrochemical corrosion between the backrail 10' and a support system, as will be described in more detail in connection with the following figures. Nose elements 28 are not present.
- edge protection elements 46 are in direct contact with the edge regions (including outer edges) of the solar module 40 and completely surround the outer edges.
- the edge protection elements 46 are distributed over the outer edge of the module 40 such that they have the conventional backrails 10 'arranged between them.
- the solar module 40 is by means of the conventional backrail 10 'in the carrier system to be explained and on, wherein suction forces are transmitted only via the edge protection elements 46 at the longitudinal ends 30 and 32 of the solar module 40.
- At the longitudinal ends 30 and 32 of the solar module 40 of FIG. 2 are each four edge protection elements 46 are arranged, whereas only two edge protection elements 46 are arranged on one of the transverse sides to avoid contact of the solar module 40 with an adjacent solar module, which in FIG 2 but not shown.
- FIG. 5 shows a perspective view of an insert carrier system 50 implemented in the form of a cross-bracing system 60.
- the carrier system 50 is hereby mounted by way of example on a house roof 52, by means of roof hooks, not shown here, which are mounted between roof tiles 54.
- the roof 52 is here inclined at 30 ° by way of example.
- the support system 50 has vertical support rails 56 which are connected in a height-adjustable manner with the roof hooks.
- the carrier system 50 also has support profiles 58 running in the horizontal direction.
- the solar module 40 is inserted into an upper horizontal support profile 58, as indicated by an arrow 62.
- the edge protector 46 abuts the support profile 58 and thus prevents an outer edge of the solar module 40 from being damaged or coming into contact with the support profile 58.
- an opposite side of the solar module 40 is inserted into a lower horizontal support profile 58.
- the solar module 40 is deposited again on the support profile 58, as indicated in FIG. 6c by an arrow 66. Thereafter, the solar module 40 is pushed down, as indicated in Fig. 6d with an arrow 68. In this case, a lower edge protector 46 abuts the lower support profile 58. Suction forces that act on the solar module 40 are transmitted from the solar module 40 in the area of the edge protection elements 46 into the support profile 58. Overloads (e.g., snow) are transferred to the support profile 58 via the backrail 10 '.
- Overloads e.g., snow
- Fig. 7 shows a side view of the backrail 10 according to the present invention, as it is already shown in perspective in Fig. 1, but here together with a solar module 40th
- the solar module 40 here has a three-layer laminate 70, consisting of an upper glass layer 72, a lower glass layer 74 and an interposed photovoltaic layer 76.
- the bottom 42 of the solar module 40 by means of a bond 80, preferably at least over the geometric length L B. a standard backrail, connected to the back rail 10 according to the invention.
- a cantilevered region 78 of the solar module 40 which essentially corresponds to the outer region or edge region of the solar module 40 mentioned above, no bond 80 is provided between the laminate 70 and the backrail 10.
- a geometric length of the cantilevered region 78 essentially corresponds to the standard distance A (usually 50 to 300 mm) mentioned in the introduction, which is required by the manufacturer for the purpose of certification.
- the backrail 10 according to the present invention also has a substantially equal geometric length L B or L s as the solar module 40.
- At the main body 12 of the backrail 10 includes at the longitudinal end 30 and 32, the at least one nose element 28 a.
- the nose element 28 does not touch the laminate 70 and projects in the height direction H by a height difference ⁇ .
- This protruding region of the nose element 28, when subjected to suction forces, ensures that the laminate 70 does not come into contact with the carrier profile 58.
- the lug element 28 also ensures that the laminate 70 can not slip off in an uncontrolled manner when the bond 80 fails. This is particularly important when the backrail 10 couples to a support profile 58 which does not overlap the laminate 70 (not shown in FIG. 7).
- Fig. 8 shows a side view of a backrail adapter 100 according to the present invention.
- the adapter 100 is here designed so that it can be plugged into a standard backrail 90 of the type described above. It is understood that the adapter 100 can be connected in other ways with the standard backrail 90 (eg by riveting, welding, gluing, screwing, etc.).
- the adapter 100 has an extension element 102, to which in the longitudinal direction L a coupling element 104 connects. In a transition region between the extension element 102 and the coupling element 104, a collar 105 may be provided which prevents the adapter 100 from being pushed too far into the standard backrail 90.
- the extension element 102 is configured such that a body of the standard backrail 90 is extended such that the geometric length L B of the standard backrail 90 is extended to the geometric length L s of the solar module 40. This makes it possible to use the solar module 40 with the standard backrail 90 in insertion systems, as described above in connection with FIGS. 6a to 6d.
- Both the nose element 28 and the extension element 102 are spaced apart from the cantilevered region of the solar module 40.
- an outer edge 112 of the solar module 40 is not in contact with the nose element 28.
- the outer edge 112 is spaced by a length AL relative to the nose element 28.
- Fig. 9 shows the adapter 100 of Fig. 8 in isolated form, i. without the solar module 40 and the standard backrail 90.
- the nose element 28 has a first section 108 which extends in the longitudinal direction L and which exceeds the geometric length L s (see Fig. 8) by the length difference AL.
- the first section 108 merges into a second section 110 that extends substantially parallel to the outer edge 112. In FIG. 9, the first portion 108 and the second portion 110 are nearly at right angles with each other.
- a third section 111 in FIG. 9 is indicated by means of a dashed line.
- the third section 111 is optional and may be arranged parallel to an upper side of the solar module 40.
- This embodiment has already been described above in connection with a carrier system in which the carrier profile 58 has no sections that overlap the solar module 40. In this case, only the third section 111 overlaps the solar module 40 and thus prevents the solar module 40 from being able to lift off the standard backrail 90 unintentionally. This aspect is of particular interest when the solar module 40 is mounted on a facade. Then, the horizontal orientation of Fig. 8 and 9 rotates in the vertical.
- FIG. 10 a section along a line X-X of Fig. 8 is shown.
- the coupling element 104 of the adapter 100 is preferably adapted in a form-fitting manner to the contour of the standard backrail 90.
- a flush and surface contacting of the back 42 of the solar module 40 for the purpose of a good power transmission is desirable.
- the coupling element 104 may also be designed differently.
- the coupling element 104 may, for example, also have a double-sided jacket shape, which is merely positively pushed onto the V-shaped support walls so that the coupling element 104 does not touch the underside 42 of the solar module 40 at all.
- the power is then transferred from the solar module 40 via the standard backrails 90 in the adapter 100, which then in turn initiates the force in the support section 58.
- the coupling element 104 may also be implemented in another form.
- the coupling element 104 may also be in the form of two nose-shaped extensions, one of which is connected to one of the V-shaped support walls (e.g., riveted, bolted, glued, welded, etc.).
- the standard backrails 90 can also have a different cross-sectional shape.
- the adapter 100 can be inserted, for example, fully and positively in a hollow shape (eg square tube) of the standard backrail 90 without touching the bottom 42 of the solar module 40.
- Fig. 11 the backrail adapter 100 of Fig. 8 to 10 is shown again in a perspective view.
