• German patent application DE202005007855 which describes a device for supporting photovoltaic cell panels with a section for holding the panels extending in a first direction, fixed on a second section forming a spacer, extending in a second direction. perpendicular to said first direction.
• JP2000154625 and JP1 10103224 are still known, which describe photovoltaic panel holding profiles consisting of an assembly of low joists, on which are referred to panel holding frames. These solutions are not satisfactory either because they do not allow to properly evacuate the hot air resulting from heating solar panels. Object of the invention
• the aim of the invention is to allow the installation of photovoltaic cell panels by taking into account at least some or all of these six problems, in order to allow a technically appropriate integration for the replacement of conventional roofs.
• the invention aims at remedying the disadvantages of the solutions of the prior art, by improving convective air circulation or by mechanical ventilation, in open chambers formed between the building surface and the rear surface of the photovoltaic panels.
• these rooms are partitioned laterally by the profiles to form hot air evacuation channels.
• the invention thus relates in particular to a device for supporting photovoltaic cell panels, consisting of a profile with a height of between 5 cm and 25 cm, comprising a central trunk, two gutters symmetrical with respect to the support and skirting the profile on its entire length, a holding rail at the base and means for fixing two panels of photovoltaic cells.
• this "height" H will be that of the central trunk.
• the support rail at the base of the central trunk supports or is taken in a rigid or semi-rigid thermal insulation
• the thermal insulation is covered with a sheet of impermeability going up along the central trunk to ensure a second level of impermeability
• Two gutters are placed in the lower part of the central trunk of the profile to allow a support of cable trays;
• the invention also relates to a photovoltaic panel support system, employing two photovoltaic cell panel support devices, wherein the two photovoltaic cell panel support devices are installed in parallel in a width-defined spacing. of the photovoltaic cell plate to be installed.
• a connecting piece makes it possible to connect the ventilation zone to an air extraction device in order to recover the heat produced by the operation of the photovoltaic cell panels;
• a connecting piece makes it possible to connect the ventilation zone to an air blower device in order to evacuate the heat produced by the operation of the photovoltaic cell panels.
• the rail ensures the mechanical fixing of the roofing or facade elements. On roof, it rests on transverse structural failures, whose spacing will be calculated according to the climatic constraints of the place, or on longitudinal rafters in the case of traditional wooden framework.
• the photovoltaic panels are screwed on the rail at the top, which gives a very high structural rigidity to all and a guarantee of non-corrosion.
• the system of the rails makes it possible to obtain a perfectly flat panel installation surface, whatever the deformations or irregularities of the framework, thanks to a setting system adjustable at each point of support. A laser adjustment can be made during the installation of the rails so as to obtain perfect flatness.
• Approved resilients are placed at the points of contact between the aluminum rail and the steel structures to avoid chemical problems.
• the rail is complemented by plastic junction pieces to both ensure flow continuity and absorb thermal expansion.
• the waterproof sheet ensures a covering of a plate on the other preventing any leakage or rise of water. It is therefore a doubly waterproof system.
• the airtightness is considered in two ways. Building waterproofing and system-specific sealing.
• the watertightness of the building is ensured by the continuity of insulating plates all over the surface.
• the system-specific sealing is what allows to consider the entire space between 2 rails as a ventilation duct.
• the air is captive between the rails, the insulating underside and the panels at the top.
• the transverse seal is ensured by the rails.
• a waterproof device is put in place.
• the purpose of the ventilation is to evacuate the calories produced by the photovoltaic system, or even to recover them for heating the building.
• the height of the air gap under the panels allows natural convective ventilation where possible. Just be sure to put in place protections against the entry of rainwater at the ends.
• the system includes parts to close the ducts created between the rails and to set up either air inlets on air supply or suction ducts, or ventilators type VMC (mechanical ventilation controlled). In any case, it will be necessary to ensure the good filtration of the air injected into the system.
• Hot air circulating in the exhaust duct can be used for heating, ventilating or cooling the building.
• the system therefore allows several configurations: natural ventilation in the open air, mechanical ventilation by suction or extraction, or dual flow ventilation.
• the thermal insulation of the building is favorably ensured by the insulating plate placed between the rails in the lower part.
• the insulating plate is taken from the rail sections, but it can also cover the lower part of the rail, which avoids the effect of condensation on a cold wall in the case of a heated building.
• This plate is threaded into the rails of the rail and can then be mechanically fixed, possibly via wedges.
• the roof or photovoltaic facade thus improves the insulation of the building by the installation of a ventilated blade of often intermediate temperature.
• This system will also be effective in very hot country (protection against heat on the roof) in cold country (protection against the effect of cold wall).
• the air circulating in the blade is, depending on the sun, often slightly heated by photovoltaic heat, the final temperature also depending on the flow rate of the ventilation.
• the system makes it possible to eliminate the effects of the expansion, whether it comes from the framework or heating of the rails.
• the length of the rails will be calculated according to the risks of expansion of the frame.
• the plastic parts which make the connection between two rails make it possible to absorb by sliding a small longitudinal expansion movement.

• Figure 3 shows another embodiment in which the central trunk (1) is drilled in the middle of holes (8) for creating crossings of transverse cables. These holes must be dimensioned by the skilled person according to the diameter of the cable or the bundling of cables to pass. The internal walls of the holes are covered with a protective material, for example a plastic ring, in order to avoid damaging passing cables and to seal them.
• the position of these notches depends on the length of the photo voltaic cell plates installed. Those skilled in the art may, for example, place the notches at regular intervals along the support, so that the middle of the notch corresponds to the junction point of the two plates.
