Description

DESCRIPTION
System for installing at least one photovoltaic panel on a support Technical field
The present invention relates to a system for installing at least one photovoltaic panel on a support.
Prior art
Solutions are known in which the photovoltaic panels are installed on a roof of a building by means of a pair of grooved rods to which fixing clips that hold the panels in position are constrained.
In this context, the technical task underpinning the present invention is to propose a system for installing a photovoltaic panel that allows to optimize the weight without penalizing the structural resistance.
Object of the invention
The defined technical task and the specified aims are substantially achieved by a system for installing a photovoltaic panel comprising the technical characteristics set forth in one or more of the appended claims.
Brief description of the drawings
Further features and advantages of the present invention will become more apparent from the illustrative and thus non-limiting description of a preferred but not exclusive embodiment of a system for installing a photovoltaic panel as illustrated in the appended figures, in which:
- figures 1 and 2 show a first embodiment of an installation system according to the present invention;
- figure 3 shows a cross section of a component of the system of figures 1 and 2;
- figures 4 and 5 show a second embodiment of an installation system according to the present invention;
- figures 6 shows a cross section of a component of the system of figures 3 and 4;
- figure 7 shows the component of figure 6 to which a connection system is applied. Detailed description of preferred embodiments of the invention
In the appended figures reference number 1 indicates a system for installing at least one photovoltaic panel on a support. Such a support is typically the roof of a building, in particular a sheet metal roof (seamed or corrugated) of a building.
The system 1 comprises a first photovoltaic panel 1 1 .
The system 1 comprises a first and a second longitudinally extending rods 21 , 22 applied to said support.
The first and second rods 21 , 22 comprise respectively a first and a second longitudinal slot 210, 220. Suitably, what is indicated in the following of this discussion for the first rod 21 can be repeated for the second rod 22. Advantageously the first and second rods 21 , 22 are identical.
The system 1 also comprises coupling means 3 for coupling the first photovoltaic panel 11 to the first rod 21 . Said coupling means 3 comprise first connection units 30. Said first connection units 30 in turn comprise a protrusion 301 that engages in the first slot 210 and at least one retaining bracket 302 for retaining the first panel 11 constrained to the protrusion 301 . Such bracket 302 comprises one or more wings 303. A portion of the edge of the first panel 11 thus remains interposed between the wing 303 and the first rod 21 .
Suitably the coupling means 3 also comprises anti-extraction means 304 constrained to the protrusion 301 and preventing the protrusion 301 from being extracted from the first rod 21. This prevents the release of the bracket 302 from the first rod 21 .
Conveniently for locking the first panel 11 two first connection units 30 are used which are applied to two opposite sides of the first photovoltaic panel 11. Advantageously the first connection units 30 comprise/coincide with screw clips. They may be positioned along the first slot 210 in the chosen position. Advantageously they are clips of the universal type. Preferably the screw of said clips is M8x55. Advantageously they allow not only to retain the first photovoltaic panel 11 , but also a possible adjacent photovoltaic panel. These clips allow an easy positioning of the panel(s) regardless of the thickness of the panel frame itself.
The system 1 also comprises coupling means 4 for coupling the first panel 11 to the second rod 22. The coupling means 4 in turn comprises second connection units 40 comprising a locking protrusion that engages in the second slot 220 and at least one retaining bracket constrained to the locking protrusion.
The first rod 21 comprises a profile having a first cross section 200 comprising stretches with thickness less than or equal to 1.6 millimetres, advantageously less than or equal to 1 .5 millimetres, preferably less than or equal to 1 .3 millimetres. These stretches are metallic.
At least 90% of the first section 200 has stretches with thickness less than or equal to 1.6 millimetres, advantageously less than or equal to 1.5 millimetres, preferably less than or equal to 1 .3 millimetres.
The first cross section 200 has a constant shape for at least 90% of the longitudinal extension of the first rod 21 .
Suitably the first cross section 200 has a constant shape for the entire longitudinal extension of the first rod 21 .
The first rod 21 has a longitudinal extension comprised between 2 and 2.5 metres.
In particular, the first rod 21 has a longitudinal extension of 2.25 metres. This measure allows to minimize waste reducing inventories in consideration of the sizes of the photovoltaic panels applied to the first rod.
The first and second rods 21 , 22 are parallel. Suitably they are placed at a distance greater than or equal to 1 .6 metres, preferably greater than or equal to 1 .7 metres. They are conveniently placed at a distance of less than 2 metres.
The first and second rods 21 , 22 are parallel and placed at a distance greater than 1 .7 metres and less than 2 metres. The first rod 21 extends in height orthogonally to a plane defined by a roof of the building. Suitably the first slot 210 extends longitudinally and is located at a top of the first rod 21 . The first slot 210 extends in depth within the first rod 21 .
As exemplified in the solution of Figure 6, the first rod 21 has a height greater than 40 millimetres (and suitably less than 50 millimetres).
As exemplified in the solution of figure 3 the first rod 21 has a height comprised between 20 and 30 millimetres and a flat base 5.
Suitably the system 1 comprises a second photovoltaic panel 12 flanked by the first photovoltaic panel 11. The second photovoltaic panel 12 is constrained to the first and second rods 21 , 22. The first and second panels 11 , 12 are thus arranged in a row. This row extends parallel to the longitudinal extension of the first and/or second rods 21 , 22. Such a row may also comprise three or more flanked panels.
Suitably the first section 200 defines an internal compartment in turn comprising:
- a first zone 201 ;
- a second zone 202.
The first slot 210 is delimited by two flaps 203, 204 leading to an enlargement 205 that defines the first zone 201. The two flaps 203, 204 are suitably folded towards the inside of the first rod 21 .
Suitably the anti-extraction means 304 are abutted by the two flaps 203, 204 preventing their extraction from the first rod 21. The anti-extraction means 304 lies in the enlargement 205.
A narrowing 206 of the first zone 201 defines the second zone 202. The first zone 201 is interposed between the first slot 210 and the second zone 202.
Suitably the first rod 21 comprises two lateral flanks 63, 64. Suitably inside the first rod 21 there are two lateral interspaces 61 , 62 with longitudinal extension. Suitably the lateral flanks 63, 64 are interposed between the second zone 202 and the lateral flanks 63, 64. Object of the present invention is also a photovoltaic system 10 comprising:
-a sheet metal roof 9 that defines said support;
-a system 1 for installing at least a first photovoltaic panel 11 having one or more of the characteristics described above.
The invention achieves important advantages.
First of all, it allows to reduce weight and therefore the cost of the first rod 21 without penalizing the resistance to mechanical stresses. It also allows the installation of the rods that support the same panel at a greater distance than known systems. The solution of figure 6 has greater height than those known and is less flexed.
The invention thus conceived is susceptible to numerous modifications and variants, all falling within the scope of the inventive concept characterizing it. Further, all the details can be replaced with other technically equivalent elements. In practice, all the materials used, as well as the dimensions, can be any whatsoever, according to need.
