Description

SUPPORT OF MODULES PHOTOVOLT AIOUES AVAILABLE ON ROOFS OR CLADDING.

The present invention relates to a cover element on which photovoltaic modules can be arranged. It concerns in particular, but not exclusively, a covering element fixed on industrial, commercial, agricultural roofs as well as on wall cladding, and which has on its visible face photo voltaic cells.

It is known that photovoltaic installations can be integrated into buildings by substituting for the traditional construction elements of buildings. In addition, these installations can be arranged on inclined roofs, at an angle generally between 7 ° and 60 °, on roof terraces, on external wall cladding, etc.

However, "integrated" support systems require the use of a large number of parts to enable their implementation and their installation on site. Structures have not been designed and sized to accommodate such systems. It is therefore necessary to carry out a prior work of adaptation of the framework, which generates a financial extra cost due to the need to use more materials and to carry out additional manipulations which increase the risk of making mistakes. The invention therefore more particularly aims to solve this problem by providing a cover element that can produce electricity, characterized in that it comprises a succession of at least one protrusion, a recess and a protuberances shaped so as to allow:

at least one photovoltaic module to bear on the upper face of at least one protuberance;

• the flow of rainwater and the passage of a flow of air that vents said modules;

and in that this covering element is monobloc and provides thermal and sound insulation as well as the tightness of the structure to which it is attached.

Thus, the cover element according to the invention provides a double function of insulation and sealing of a structure such as a frame, but also a support function of photovoltaic modules.

This specific coverage element, which includes photovoltaic modules, provides a function of closed and covered, which is not the case of conventional photovoltaic modules, the latter generally requiring to be integrated into specific frames to be able to guarantee good insulation.

Advantageously, the photovoltaic modules are fixed to the cover element in the factory, which makes it easier to install the assembly, this fixing photovoltaic modules do not need to be performed in the field by the technician.

Preferably, the cover element according to the invention comprises at its longitudinal edges assembly means shaped so as to be able to bear on elements of the structure on which the covering element is arranged and / or on the assembly means of the adjacent cover element, these assembly means being able to consist of latching lips. According to an alternative embodiment of the invention, the cover element comprises successively, along a transverse axis:

At each of the longitudinal edges of the cover member, a first longitudinally-oriented hooking lip comprising a web extended at its outer longitudinal edge by a return wing;

A first groove oriented longitudinally, extending the internal longitudinal edge of the core of the attachment lip;

• a succession of at least one protuberance, a recess, and a protuberance oriented longitudinally, each protuberance having a flat upper face substantially parallel to the median longitudinal plane of said cover member; in addition, preferably, the height of each protuberance is substantially less than or equal to that of said hooking lip, and each recess has:

a depth substantially equal to that of the first groove;

a width substantially equal to or greater than that of the first groove;

• a second groove of the aforementioned type, longitudinally oriented, which extends the last protuberance; this second groove preferably has the same dimensions as those of said first groove;

A second hooking lip of the aforesaid type, longitudinally oriented, which extends the second longitudinal groove, this second hooking lip preferably has the same dimensions as those of said first lip. Preferably, the photovoltaic modules are fixed on the covering element according to the invention by gluing, the upper faces of each of said protuberances each comprising at least one self-adhesive strip in contact with the underside of a corresponding photovoltaic module.

According to another variant of preferential embodiment, the cover element comprises successively, along a transverse axis:

At each of the longitudinal edges of the cover element, a first hooking lip of the aforesaid type, longitudinally oriented;

• a first groove, longitudinally oriented, extending the inner longitudinal edge of the core of the first latching lip;

• a succession of two series of elements each composed of a protuberance, a recess, another protuberance of the aforesaid type, longitudinally oriented, these two series of elements being separated by a central recess oriented longitudinally;

A second groove of the aforesaid type, longitudinally oriented, which extends the last protuberance of the second series;

• A second hooking lip of the aforesaid type, longitudinally oriented, which extends the second longitudinal groove.

According to another alternative embodiment of the invention, at least the two end protuberances may each comprise on their upper face a recess preferably having a semicircular cross section. These recesses which extend longitudinally advantageously make it possible to dispose the cables of the connection boxes, these cables making it possible to drain the current produced by a row of photovoltaic modules. Thus, the covering element according to the invention has the following advantages in particular:

• it reduces the number of parts needed for the installation of photovoltaic modules;

· The factory production time is reduced;

• The exposure time is reduced: the roofing elements according to the invention are ready to be installed directly on the frame without using frames, unlike existing devices that do not allow them - alone to provide a function d sealing and insulation, and which need to be laid on a pre-existing roof;

• the waterproofing and insulation are preserved because the roofing elements do not undergo any breakthrough during their manufacture;

The installation of the covering elements according to the invention does not require modifications of the framework;

· The weight of the set is small;

• it allows the installation of almost all frameless photovoltaic modules;

• the efficiency and cooling of the assembly are improved due to the presence of said grooves and said recesses;

· It can be installed on roofs or as wall cladding.
