Modular Element With Photovoltaic Module

Abstract

The invention relates to a modular construction element used to close a building roof, in particular a flat roof, comprising a first face inclined with respect to a horizontal plane, having at least one transparent or translucent portion suitable for allowing natural light to illuminate the inside of the building; a second face inclined with respect to a horizontal plane, of opposite orientation to the first face, having at least one solar panel comprising at least one photovoltaic module; and at least part of the faces of the modular element comprising at least one thermal and / or acoustic insulation layer.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to a modular construction element used to close a building roof, in particular a flat roof. The invention further relates to a roof comprising at least one modular element according to the invention.DESCRIPTION OF THE PRIOR ART[0002]Conventionally, building roofs, for example of warehouses or factories, take the form of flat roofs. In certain cases, it may happen that these roofs are closed by roofs of substantially prismatic shape, which are called shed roofs. More precisely, these roofs have translucent portions comprising glass panes arranged so as to be steeply inclined on the north side for the purpose of obtaining diffuse light inside the building, better known by the name “skylight”. Furthermore, these roofs may include a solar collector, placed for example so as to be oriented facing south, this particular orientation enabling the solar collector to be more effective. Such a roof is known in particular from document DE 2...

Benefits of technology

[0005]The present invention aims to solve completely or partly these drawbacks by providing a modular construction element that makes it easier to produce such a type of roof and to integrate solar panels. For this purpose, the subject of the invention is a modular construction element used to close a building roof, in particular a flat roof, comprising a wall having a first face inclined with respect to a horizontal plane, having at least one transparent or translucent portion suitable for allowing natural light to illuminate the inside of the building; a second face inclined with respect to a horizontal plane, of opposite orientation to the first face, having at least one solar panel comprising at least one photovoltaic module; and at least part of the faces of the modular element comprising at least one thermal and / or acoustic insulation layer.

[0006]Thanks to the arrangements according to the invention, the production of such a modular element allows the number of solar panels and the overall illumination area to be adapted to the dimensions offered by the building roof, while still ensuring thermal and / or acoustic protection on the roof. The term “overall illumination” comprises direct illumination, diffuse illumination and albedo illumination.

[0010]This feature has the benefit of being simple to implement since glass wool is flexible from the mechanical standpoint and is advantageous in terms of weight and cost compared with other materials.

[0014]Such an inclination of the solar panel provides optimum efficiency of the photovoltaic modules placed on the surface of the solar panel.

[0016]This arrangement makes it possible to provide diffuse light inside the building.

Problems solved by technology

However, the construction of such a roof having several separate construction components is complicated and its design by architects depends on the dimensions of the building.

This is because the integration of solar panels on such a structure is complicated if it is desired to ensure cooling, insulation and positioning conditions that allow the panel to operate satisfactorily.

In addition, once the components have been positioned, the sealing and the thermal protection of the roof in its entirety are tricky to achieve given the heterogeneous assembly formed by this roof.
