Description

KIT AND METHOD FOR MOUNTING A SOLAR PANEL TO A ROOF
AND SOLAR PANEL
This invention further relates to a kit and a method for mounting a solar panel to a roof and a solar panel.
More specifically, the term "solar panel" means both a thermal panel and a photovoltaic panel, and a so-called hybrid panel, that is, both thermal and photovoltaic.
This invention relates in particular to the sector of solar panels made, for example, from ceramic material designed to support, for example, a plurality of photovoltaic cells. The solar panels are, for example, without supporting and/or containment frames.
More specifically, this invention refers to the sector of solar panels designed to replace the covering of tiles normally provided to protect the surface of the roof.
It should be noted that, for the purpose of this description and the following claims, the term "roof" means the load-bearing structure forming the upper part of a building whilst the term "covering" of the roof means the upper layer normally made of tiles and/or solar panels which should also provide protection against water infiltration.
Moreover, the term "slope direction" means a direction parallel to a slope of the roof. The term "ridge line" means a straight line preferably horizontal of maximum height which is obtained by the intersection between two inclined slopes of the roof whilst the term "eaves line" means a straight line preferably horizontal of minimum height which is obtained, for example, by the intersection between inclined slopes with a horizontal plane.
Moreover, the term "transversal member" means an element higher than a surface of the roof and generally having a main line of extension positioned transversely to the slope direction, for example horizontal. The term "transversal" means that the transversal member may be positioned perpendicularly to the slope direction or slightly inclined to it. With reference to the arrangement of the solar panels on the roof, it is possible to define a "vertical sequence" formed by two or more solar panels positioned adjacent to and/or superposed along the slope direction and a "horizontal sequence" formed by two or more solar panels positioned adjacent to and/or superposed in a direction transversal to the slope direction, for example in a direction parallel to the ridge and/or eaves line. A covering of a roof using solar panels can comprise one or more vertical and/or horizontal sequences of solar panels.
Considering the four sides which form the perimeter of a panel, the term "lateral edge or portion" means the edges or portions positioned parallel to the slope direction in an assembled configuration of the panel. Whilst the terms "upper edge or portion" or "lower edge or portion" mean the edges or portions positioned parallel to the ridge line in an assembled configuration of the panel proximal to or distal from, respectively, the ridge line. More specifically, the term "upper portion" of a solar panel positioned as covering of a roof means its portion closest to the ridge line. Vice versa, the term "lower portion" of a solar panel positioned as covering of a roof means its portion closest to the eaves line.
Two adjacent and/or superposed panels which form a horizontal sequence are located alongside or superposed at the relative lateral edges or lateral portions of the panels whilst two adjacent and/or superposed panels which form a vertical sequence are located alongside or superposed at the relative upper and/or lower edges or portions. With reference to this invention, the term "above" means an area of the solar panel positioned at an upper edge or portion of the panel.
With reference to the solar panel positioned as covering of a roof, the term "front surface" means the active surface of the panel, that is, the one facing the outside, whilst the term "rear surface" means the hidden surface, that is, the one facing the roof and the transversal members.
To mount the solar panels on the roof it is necessary to rest them on the transversal members of the roof in such as way as to prevent them sliding downwards (that is, towards the eaves line). In windier regions, or to increase the safety, it is necessary to fix the solar panel to the transversal members, so as to prevent not only the panel from sliding downwards but also the generation of pressure differences by the wind which could lift the panel from the transversal members.
When positioning the solar panels on the transversal members of the roof it is necessary to take into consideration the inevitable imperfections in alignment and flatness of the transversal members.
For this purpose, the rear surface of the solar panel is fitted with at least one guide wherein an arm of an L-shaped element can slide along a direction parallel to the slope direction, with reference to a configuration with the solar panel mounted on the roof. The L-shaped element is positioned along the guide in a position deemed suitable to compensate for any imprecisions of the roof and fixed by screws positioned and screwed perpendicularly to the lower surface of the solar panel. The other arm of the L-shaped element is designed to abut against a transversal member of the roof in such a way that the L-shaped element forms a hook with which the solar panel is substantially suspended from the transversal member and rests on it.
The Applicant has found that use of the prior art devices requires a high level 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 problem of the prior art devices is that the means for locking the L-shaped element (screws) are designed in such a way as to be activated (screwed) after 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 by the user by providing a spacer element having a contact surface designed to rest against a transversal member of the roof and locking means designed to operate on the spacer element for preventing the relative movement with respect to the solar panel wherein the locking means are designed in such a way as to be activated above the solar panel, that is, with the panel already correctly aligned.
According to a first aspect, this invention relates to a kit for mounting a solar panel to a roof. At least one spacer element comprises at least one contact surface designed to rest against a transversal member of the roof which is positioned transversally to a slope direction for preventing the solar panel from sliding towards an eaves line of the roof. The spacer element is designed to be mounted on the solar panel in at least two adjustment positions which correspond to two different positions of the contact surface relative to the solar panel. Locking means designed to operate on the spacer element for fixing it in one of the adjustment positions depending on the position of the solar panel relative to the transversal member are designed in such a way that they are activated above the solar panel when the kit is in the assembled configuration and with the solar panel mounted on the roof.
According to a possible embodiment, a kit for mounting a solar panel to a roof comprises at least one spacer element designed to be mounted in such a way that it can move along the solar panel at least according to a movement direction designed to allow it to be positioned parallel with a slope direction of the roof when the kit is in the assembled configuration and with the solar panel mounted on the roof. The spacer element comprises at least one contact surface designed to rest against a transversal member of the roof which is positioned transversally to the slope direction for preventing the solar panel from sliding towards an eaves line of the roof. Locking means are designed to operate the spacer element to prevent it from moving relative to the solar panel in the movement direction. The locking means are designed in such a way that they are activated above the solar panel when the kit is in the assembled configuration and with the solar panel mounted on the roof. According to a first aspect, this invention relates to a solar panel comprising at least one kit for mounting a solar panel to the roof wherein the kit comprises a portion which is glued to a rear surface of the solar panel.
According to a further aspect, this invention relates to a method for mounting a solar panel to a roof. More specifically, the following is possible:
resting the solar panel on transversal members of the roof which are positioned transversally to a slope direction of the roof in a position aligned with an external reference, for example an adjacent panel;
mounting and positioning at least one spacer element relative to the solar panel according to a movement direction preferably parallel with the slope direction of the roof so that a contact surface of the spacer element rests against a transversal member of the roof;

Preferably, the spacer element 16 is positioned in such a way that it is subject to compression along the axial direction 17, when the kit is in the assembled configuration and with the solar panel mounted on the roof. The compression is generated by the weight of the solar panel which rests on the transversal member 15 using the spacer element 16.
In general, the locking means are designed to form a locking portion 25 which is fixed relative to the solar panel. In the example illustrated the fixed locking portion is formed by the cavity 20 for example threaded.
In general, the contact surface 18 is designed to allow it to be positioned downstream of the locking portion 25 formed by the locking means, with reference to a slope direction 4 in the direction formed between a ridge line 5 and an eaves line 6, when the kit is in the assembled configuration and with the solar panel mounted on the roof.

The additional bracket 26 and the bracket 19 can comprise mutual contact surfaces 29 which are shaped to define a sequence of separate relative positions. More specifically, the mutual contact surfaces 29 have a zigzag shape or undulating profile.
The bracket 19 can comprise a through cavity 30 for an element 31 for fastening to the transversal member 15 of the roof. The fastening element 31 is designed to allow it to be positioned parallel to the slope direction and/or the direction of movement 17. More specifically, there is a threaded pin designed to be screwed to the transversal member 15 of the roof.
The additional bracket 26 comprises a through cavity 32 for the element 31 for fastening to the transversal member 15 of the roof.
Preferably, the kit comprises a portion 33 which is glued to the rear surface 14 of the solar panel 3. More specifically, the portion comprises at least a part of the bracket 19, preferably the anchoring plate 21 , which is glued to the rear surface 14 of the solar panel 3.
According to a possible embodiment, for example different from that 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. There is also a stop portion 36 positioned substantially parallel to the rear surface 14 of the solar panel 3.
A connecting portion 37 is positioned in such a way as to leave an air space 38 between the stop portion 36 and the rear surface 14 of the panel. The air gap is designed to receive an upper portion 1 1 of an adjacent solar panel along the same vertical sequence.
The gluing portion 35 comprises two resting elements 39 which are distanced from each other. The two resting elements 39 project towards the rear surface 14 of the solar panel 3. The two resting elements 39 form a gap 40 for an adhesive component.
One resting element 39 is preferably formed by a rib positioned for example transversally to the direction of movement 17 and/or the slope direction 4.
According to a possible embodiment, for example different from that described above, the solar panel 3 comprises a channel 41 positioned along one side 9, 10 of the solar panel 3 and designed to be positioned parallel with the slope direction 4, when the kit is in the assembled configuration and with the solar panel mounted on the roof. The channel 41 comprises a first surface 42 designed for being placed in contact, in particular fixed, to the rear surface 14 of the solar panel 3. A second surface 43 is designed for receiving in a resting fashion an adjacent solar panel along a horizontal sequence of the solar panels.
A drainage channel 44 is positioned between the first surface 42 and the second surface 43.
The first surface 42 and/or the second surface 43 end with a bent stretch 45 designed to stiffen the channel. The bent stretch 45 extends parallel to the side of the panel for a stretch less than the length of the channel, leaving a free portion 46 at an end of the channel designed to overlap a channel of an adjacent solar panel along a vertical sequence of solar panels. The present invention further relates to a method for mounting a solar panel to a roof comprising:
resting the solar panel 3 on transversal members 15 of the roof which are positioned transversally to a slope direction 4 of the roof in a position aligned with an external reference, for example an adjacent panel, mounting and positioning at least one spacer element 16 relative to the solar panel according to a movement direction 17 for example parallel with the slope direction 4 of the roof so that a contact surface 18 of the spacer element rests against a transversal member 15 of the roof,
locking the spacer element 16 to prevent it from moving relative to the solar panel in the movement direction 17 by activating locking means which are above the solar panel.
Preferably, the method according to this invention comprises inserting the upper edge of a panel already positioned inside an air space 38 of a stop element associated with a panel adjacent to and above a vertical sequence. The two solar panels are partly superposed.
This invention achieves the set aim and overcomes the disadvantages of the prior art, providing locking means designed in such a way that they are activated above the solar panel when the kit is in the assembled configuration and with the solar panel mounted on the roof.
The kit according to this invention allows adjustments to the position of the solar panel to be made, making adjustments of even greater than 2 cm. The bracket 19 comprises a contact element and rests against the relative transversal member 15 irrespective of the the presence of the spacer element 16. The spacer element 16 can be used when the imperfections of the roof structure require adjustments to the position of the panels of for example +/-2cm so that they are aligned.
The additional bracket can be used to allow greater adjustments, of for example up to 6 cm, as it annuls the transversal forces on the spacer element, thus preventing the bending.
The kit according to this invention does not require pre-assembly. More specifically, 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 equipped with photovoltaic cells and cut to size in situ.
The bracket 19 in particular comprising the contact plate (for example "T"- shaped), allows the edge of the panel, in particular the corner, to be protected when it is rested on its edge during the transport and assembly steps.
The presence of the stop element guarantees the coupling between two adjacent panels.
The presence of the channel allows both the water to be drained and the support to be stiffened, allowing a greater treadability of the covering. Moreover, it allows further stiffening elements to be avoided, makes the structure lighter, limits the thickness of the solar panels also with support centre distances of approximately 1 metre.
As an alternative to what is described and illustrated above, the bracket 19 could be made as an element entirely passed through by the cavity 20 (and, if necessary, by the through cavity 30) for example in the shape of a parallelepiped rather than "L" or "T"-shaped.
