DESCRIPTION

"KIT AND METHOD FOR THE ASSEMBLY OF A SOLAR PANEL AD

A ROOF AND SOLAR PANEL "

The present invention relates to a kit and a method for mounting a solar panel to a roof and a solar panel.

In particular, a solar panel means both a thermal panel, a photovoltaic panel and a so-called hybrid panel, i.e. both thermal and photovoltaic.

The present invention relates in particular to the sector of solar panels made of material, for example ceramic, suitable for supporting, for example, a plurality of photovoltaic cells. Such solar panels are for example without support and / or containment frames.

In particular, the present invention relates to the sector of solar panels suitable for replacing the tile covering normally provided to protect the roof surface.

It should be noted that, for the purposes of the present description and the subsequent claims, the term "roof" means the load-bearing structure defining the upper part of a building, while the term "roof" means the upper mantle generally made of tiles and / or solar panels which should also provide protection from water infiltration.

Furthermore, the term "pitch direction" means a direction parallel to the inclination of a roof pitch. The term "ridge line" means a preferably horizontal line of maximum height which is obtained as the intersection between two inclined pitches of the roof while the term "eaves line" means a preferably horizontal line of minimum height which is obtained by example as an intersection between the inclined slopes with a horizontal plane.

Furthermore, the term "crosspiece" means an element which rises with respect to a surface of the roof and generally having a prevailing line of development arranged transversely to the direction of the pitch, for example horizontal. The term "transverse" means that the crosspiece can be arranged perpendicular to the direction of the pitch or slightly inclined with respect to it.

With reference to the arrangement of solar panels on the roof, it is possible to define a "vertical sequence" defined by two or more solar panels arranged adjacent and / or superimposed along the direction of the water table and a "horizontal sequence" defined by two or more solar panels arranged adjacent and / or superimposed in a direction transverse to the direction of the pitch, for example in a direction parallel to the ridge and / or eaves line. A roof covering using solar panels can consist of one or more vertical and / or horizontal sequences of solar panels.

Considering the four sides that define the perimeter of a panel, with edge or side portion we mean the edges or portions arranged parallel to the direction of the pitch in the assembled configuration of the panel. While the upper or lower edge or portion means the edges or portions arranged parallel to the ridge line in the assembled configuration of the panel respectively proximal or distal with respect to the ridge line. In particular, the term "upper portion" of a solar panel arranged to cover a roof means its portion closest to the ridge line. Conversely, the term "lower portion" of a solar panel arranged to cover a roof means its portion closest to the eaves line.

Two adjacent and / or overlapping panels that form a horizontal sequence are juxtaposed or overlapped in correspondence with relative side edges or side portions of the panels themselves while two adjacent and / or overlapping panels that form a vertical sequence are juxtaposed or overlapped in correspondence of relative edges or upper and / or lower portions. With reference to the present invention, the term "above" means an area of the solar panel arranged at an edge or an upper portion of the panel.

With reference to the solar panel arranged as a roof covering, the term "front surface" means the active surface of the panel itself, ie the one facing outwards, while the term "rear surface" means the hidden surface, ie the facing the roof and crossbeams.

To mount the solar panels on the roof, they must be placed on the roof crosspieces in order to at least prevent them from sliding downwards (i.e. towards the eaves line). In the windiest regions, or to increase safety, it is necessary to provide a real fixing of the solar panel to the crossbars, in order not only to prevent the panel from sliding downwards but also that the wind can generate pressure differences such as to raise the panel from the crosspieces themselves.

When positioning the solar panels on the roof beams, the inevitable alignment and flatness imperfections of the beams must be taken into consideration.

For this purpose it is known to fix to the rear surface of the solar panel at least one guide in which an arm of an "L" -shaped element can slide along a direction parallel to the direction of the pitch, with reference to a configuration mounted on the roof of the solar panel. The "L" element is positioned along the guide in a position that is considered suitable for balancing any inaccuracies in the roof and fixed by means of screws arranged and screwed perpendicularly to the lower surface of the solar panel. The other arm of the "L" -shaped element is intended to abut against a crossbar of the roof so that the "L" shaped element forms a hook with which the solar panel is substantially hung on the crosspiece and resting on it.

The Applicant has found that the use of known devices requires a great deal of experience and skill since it is necessary to decide the correct position of the "L" -shaped element before positioning the solar panel and therefore without references.

The Applicant has perceived that the aspect which determines this criticality of the known devices is constituted by the fact that the locking means of the "L" -shaped element (screws) are configured in such a way as to be activated (screwed) at the rear with respect to the solar panel. The Applicant has found that the position and alignment of the solar panels can be adjusted with precision and without the need for particular experience on the part of the user by providing a spacer element having an abutment surface suitable for resting against a crossbar of the roof and locking means adapted to operate on the spacer element to prevent its relative movement with respect to the solar panel in which the locking means are configured so as to be activated above the solar panel, ie with the panel already correctly aligned.

In accordance with a first aspect, the present invention relates to a kit for mounting a solar panel to a roof. At least one spacer element comprises at least one abutment surface suitable to rest against a roof cross member arranged transversely to a pitch direction to prevent the solar panel from sliding towards an eaves line of the roof. The spacer element is suitable for being mounted on the panel in at least two adjustment positions corresponding to two different relative positions of the abutment surface with respect to the solar panel. Locking means, suitable for operating on the spacer element to fix it in one of the adjustment positions according to the position of the solar panel with respect to the crosspiece, are configured so as to be activated above the solar panel in the assembled configuration of the kit and in configuration mounted on the roof of the solar panel. In accordance with a possible embodiment, a kit for mounting a solar panel to a roof comprises at least one spacer element suitable for being mounted movable along the solar panel at least according to a direction of displacement suitable for arranging itself parallel to a direction of the pitch. of the roof in the kit assembled configuration and in the solar panel roof-mounted configuration. The spacer element comprises at least one abutment surface suitable for resting against a roof cross member arranged transversely to the pitch direction to prevent the solar panel from sliding towards an eaves line of the roof. Locking means are adapted to operate on the spacer element to prevent its relative movement with respect to the solar panel according to the direction of displacement. The locking means are configured so as to be activated above the solar panel in the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel.

In accordance with a second aspect, the present invention relates to a solar panel comprising at least one kit for mounting the solar panel to the roof in which the kit comprises a portion glued to a rear surface of the solar panel.

In accordance with a further aspect, the present invention relates to a method for mounting a solar panel to a roof. In particular, it is planned to:

Figure 1 illustrates four solar panels 3 defining two vertical sequences 7 and two horizontal sequences 8.

With reference to a solar panel mounted on the roof, numbers 9 and 10 indicate respective lateral edges or side portions of the panels themselves, while numbers 11 and 12 indicate relative upper and lower edges or upper and lower portions of the panels themselves. Furthermore, 13 indicates a front surface of the solar panel while 14 indicates a rear surface of the solar panel itself.

The solar panels mounted to cover the roof rest on crossbeams 15. The crossbars are constituted for example by tubular profiles arranged transversely to the direction of the pitch, for example.

A kit for mounting a solar panel to the roof comprises at least one spacer element 16 suitable for assuming at least two adjustment positions along the solar panel, in particular along a direction of movement 17.

The spacer element 16 comprises at least one abutment surface 18 suitable for resting against a crosspiece 15 to prevent the solar panel from sliding towards the gutter line 6.

The at least two adjustment positions of the spacer element correspond to two different relative positions of the abutment surface 18 with respect to the solar panel 3.

In the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel, the direction of movement 17 is preferably arranged transversely to the ridge line 5 and / or to the eaves line 6.

In particular, in the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel, the direction of movement 17 is arranged parallel to the direction of the pitch 4.

The reference number 19 indicates a bracket suitable to be fixed to the solar panel 3, preferably to the rear surface 14 of the solar panel, on which the spacer element 16 is mounted movably along the direction of movement 17.

The bracket 19 comprises at least one seat 20 in which the spacer element 16 is suitable for being inserted. Preferably the seat 20 extends along a direction suitable for defining the displacement direction 17.

The bracket 19 comprises an anchoring plate 21 to the solar panel adapted to be arranged parallel to and adjacent to the rear surface 14 of the solar panel. In particular, a surface 21a is suitable for being arranged in contact with the rear surface 14 of the solar panel 2.

Furthermore, a locking plate 22 is provided which is arranged transversely to the anchoring plate 21.

In the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel, the locking plate 22 is adapted to extend away from the rear surface 14 of the solar panel towards the roof.

The locking plate 22 comprises the seat 20 for the spacer element 16.

In particular, the pin is suitable for fitting into the seat 20 of the bracket.

For example, the pin has at least one external threaded portion 24 for coupling with an internally threaded seat 20. The coupling between the threaded seat 20 and the threaded pin defines locking means.

In particular, the locking means are suitable for operating on the spacer element 16 to fix it in one of the adjustment positions according to the position of the solar panel with respect to the crosspiece. Furthermore, the locking means are configured so as to be activated above the solar panel in the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel. In fact, for example, by screwing or unscrewing the threaded pin with respect to the seat 20, the pin itself is fixed in the desired adjustment position.

In general, the locking means can be threaded locking means, for example suitable for operating on the spacer element to prevent its relative movement with respect to the bracket, in particular to the locking plate of the bracket, in a direction parallel to a direction of flap 4 in the assembled kit configuration and in the configuration mounted on the roof of the solar panel.

In particular, the locking means are suitable for operating on the spacer element to prevent its relative movement with respect to the solar panel according to the direction of movement 17.

In general, at least a portion of the locking means is movable along the displacement direction 17 and is preferably integrated in the spacer element. According to the illustrated example, the threaded pin in particular defines the movable portion of the locking means.

In general, the spacer element 16 extends along an axial direction, preferably coinciding with the direction of displacement 17.

Preferably the spacer element 16 is arranged so as to be subjected to compression along the axial direction 17, in the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel. The compression is generated by the weight of the solar panel which rests on the crosspiece 15 by means of the spacer element 16.

In general, the locking means are suitable for defining a locking portion 25 fixed with respect to the solar panel. In the illustrated example, this fixed locking portion is defined by the seat 20, for example threaded.

In general, the abutment surface 18 is suitable to be arranged downstream of the locking portion 25 defined by the locking means, with reference to a direction of the pitch 4 traveled in the direction defined between a ridge line 5 and an eaves line 6, in assembled configuration of the kit and in configuration mounted on the roof of the solar panel.

The auxiliary bracket 26 is L-shaped.

Fixing means can be provided that can be adjusted along a direction suitable for example to be arranged parallel to the direction of the pitch 4, in the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel, to fix the auxiliary bracket 26 with respect to the solar panel 3, preferably to the anchor plate 21 of the bracket 19.

In general, the fixing means of the auxiliary bracket can be adjusted along the direction of displacement 17 of the spacer element 16.

In particular, the auxiliary bracket 26 has at least one slot 28 elongated along a direction suitable to be arranged parallel to the direction of the pitch 4 and / or to the direction of displacement 17, in the assembled configuration of the kit and in the configuration mounted on the roof of the solar panel. At the slot 28, the bracket 19 and in particular the anchoring plate 21 has holes 28a for receiving screws or similar elements for fixing the auxiliary bracket 26 to the bracket 19.

The auxiliary bracket 26 and the bracket 19 may comprise reciprocal contact surfaces 29 shaped to define a sequence of discrete relative positions. In particular, the reciprocal contact surfaces 29 are shaped in a zig-zag or with a corrugated profile.

The bracket 19 can comprise a through seat 30 for a hooking element 31 to the roof crosspiece 15. The hooking element 31 is suitable to be arranged parallel to the pitch direction and / or to the displacement direction 17. In particular, a threaded pin is provided which is suitable to be screwed to the crosspiece 15 of the roof.

The auxiliary bracket 26 comprises a through seat 32 for the hooking element 31 to the roof crosspiece 15.

Preferably, the kit comprises a portion 33 glued to the rear surface 14 of the solar panel 3. In particular, this portion consists of at least a part of the bracket 19, preferably the anchoring plate 21, glued to the rear surface 14 of the solar panel 3.

In accordance with a possible embodiment, for example independent from what has been described above, the solar panel 3 comprises a stop element 34.

The stop element 34 comprises a portion 35 for gluing to the rear surface 14 of the solar panel 3. A stop portion 36 is also provided, arranged substantially parallel to the rear surface 14 of the solar panel 3.

A connecting portion 37 is arranged so as to leave a gap 38 between the stop portion 36 and the rear surface 14 of the panel. The interspace is adapted to receive an upper portion 11 of an adjacent solar panel along the same vertical sequence.

The gluing portion 35 comprises two supports 39 spaced apart. The two supports 39 project towards the rear surface 14 of the solar panel 3. The two supports 39 define an interstice 40 for an adhesive component.

A support 39 is preferably formed by a rib arranged for example transversal to the direction of movement 17 and / or to the direction of the flap 4.

In accordance with a possible embodiment, for example independent from what has been described above, the solar panel 3 comprises a duct 41 arranged along a side 9, 10 of the solar panel 3 suitable to be arranged parallel to the direction of the water table 4, in an assembled configuration of the kit and in the configuration mounted on the roof of the solar panel. The duct 41 comprises a first surface 42 suitable for being placed in contact, in particular fixed, to the rear surface 14 of the solar panel 3. A second surface 43 is suitable for receiving in support an adjacent solar panel along a horizontal sequence of solar panels.

A drainage channel 44 is disposed between the first surface 42 and the second surface 43.

The first surface 42 and / or the second surface 43 terminate with a folded portion 45 suitable for stiffening the raceway. The folded portion 45 extends parallel to the side of the panel for a portion shorter than the length of the duct, leaving a free portion 46 at one end of the duct itself suitable for overlapping a duct of an adjacent solar panel along a vertical sequence of solar panels.

The present invention also relates to a method for mounting a solar panel to a roof comprising:

place the solar panel 3 on roof crosspieces 15 arranged transversely to a pitch direction 4 of the roof itself in a position aligned with an external reference, for example an adjacent panel,

mount and position at least one spacer element 16 with respect to the solar panel in a direction of displacement 17, for example parallel to the pitch direction 4 of the roof until an abutment surface 18 of the spacer element rests against a crosspiece 15 of the roof,

blocking the spacer element 16 to prevent its relative movement with respect to the solar panel according to said movement direction 17 by activating locking means above the solar panel. Preferably, the method according to the present invention provides for inserting the upper edge of a panel already positioned inside a gap 38 of a stop element associated with an adjacent and upper panel with respect to a vertical sequence. The two solar panels are partially overlapped.

The present invention achieves the proposed object, overcoming the drawbacks complained of in the known art by providing locking means configured so as to be activated above the solar panel in the assembled configuration of the kit and in a configuration mounted on the roof of the solar panel. The kit according to the present invention allows to adjust the position of the solar panel by making adjustments even higher than 2 cm.

The bracket 19 constitutes an element of abutment and support against the relative crosspiece 15 independent of the presence of the spacer element 16. The spacer element 16 can be used when the imperfections of the roof structure need to adjust the position of the panels to example of / -2cm so that they are aligned.

The auxiliary bracket can be used to allow for greater adjustments, for example up to 6 cm since it cancels the transverse forces on the spacer element and prevents it from bending.

The kit according to the present invention does not require pre-assembly. In particular, the bracket 19 can be supplied directly glued (or otherwise fixed) to the solar panel or as a separate element, to be used for example in the case of end portions not provided with photovoltaic cells and cut to size on site.

The bracket 19 alone, in particular comprising the abutment plate (for example shaped in a "T" shape), allows to protect the edge of the panel, in particular the corner, when it is placed on cutting during the transport and assembly phases.

The presence of the stop element guarantees the coupling between two adjacent panels.

The presence of the channel allows both to drain the water and to stiffen the support, allowing greater walkability of the roof. It also allows to avoid further stiffening elements, to make the structure lighter, to limit the thickness of the solar panels even with support distances of about 1 meter.

As an alternative to what has been described and illustrated, the bracket 19 could be made as an element entirely crossed by the seat 20 (and possibly by the through seat 30) for example in the shape of a parallelepiped rather than in the shape of an "L" or "T".
