Description

PHOTOVOLTAIC PANEL SUPPORT SYSTEM AND CORRESPONDING SUPPORT METHOD

The present invention relates to the general technical field of renewable energies, especially in the field of solar energy.

The present invention relates in particular to the technical field of photovoltaic panels that allow the conversion of solar energy into electrical energy.

The present invention more specifically relates to a system for supporting at least one photovoltaic panel on a frame.

The present invention also relates to a method for installing a system for supporting at least one photovoltaic panel on a frame.

The present invention furthermore relates to a computer program comprising computer program code means adapted to execute the steps of a method of installing a system for supporting at least one photovoltaic panel on a frame, when said program is run on a computer.

Finally, the present invention relates to a computer-readable medium on which is recorded a computer program adapted to perform the steps of a method of installing a system for supporting at least one photovoltaic panel on a computer. a building.

It is traditional to now use renewable energies as an alternative to fossil fuels, which are particularly polluting and have natural reserves that tend to run out. In particular, the use of solar energy to produce electrical energy is developing, in particular through the use of photovoltaic cells composed mainly of a silicon-based material and able to convert the solar energy received. B90545 / FR In general, photovoltaic cells are grouped together in the form of panels forming photovoltaic panels, commonly called "solar panels", an outer face of which captures solar energy and a lower surface converts the received solar energy into electrical energy. The solar panels are arranged on various surfaces in such a way that the photovoltaic cells they comprise are able to capture a maximum of solar rays, so that the energy efficiency of the solar panels is optimal.

Different methods of fixing these solar panels on various receiving surfaces are known. It is possible to fix them on an inclined roof of a building, for example directly on the frame or at the level of the tiles of said building. In this case, the receiving surface is important and the energy efficiency interesting.

However, this first mode of attachment has a number of disadvantages. First of all, it is particularly difficult to access and maintain since the panels are fixed on a sloping roof. In addition, it does not allow sufficient space between the lower surface of the panels and the roof to allow ventilation of the lower surface of the panels. However, it is in this specific place that a heat release takes place during the conversion of solar energy into electrical energy. Thus, poor ventilation of the back of the solar panel can lead to a risk of overheating. Finally, this first method of fixing generally affects the tightness of the roof since it is necessary to drill the frame or remove tiles to fix the panels, which necessarily increases the risk of water infiltration.

Alternatively, it is also possible to fix the solar panels directly on flat surfaces, for example on a flat roof, according to a second method of attachment. In this case, the solar panels can for example be positioned flat on the roof, to occupy the largest area of the roof. This second method of attachment if it facilitates maintenance and handling compared to solar panels fixed on a sloped roof, does not present fewer disadvantages. In particular, the often numerous fixing points of the panels directly on the roof can cause infiltrations of rainwater in the sealing of the latter. In addition, the flat positioning of the panels promotes on the one hand the creation of heating under the panels, unless the latter B90545 / FR are slightly raised above the roof, and on the other hand the accumulation of dust that reduce the efficiency of solar panels. In fact, the efficiency of the photovoltaic cells generally decreases by about 0.45% per degree centigrade above 25 ° C. and the temperature under an unventilated panel can reach 90 ° C. In addition, the accumulation of dust on the surface of photovoltaic panels laid flat reduces their effectiveness.

In order to reduce some of the aforementioned disadvantages, it is also known to fix solar panels on a flat roof inclined with respect to the roof surface, in particular using transverse support bars on which the panels rest. In general, the solar panels are arranged such that they form several rows substantially parallel to each other.

This second method of fixing avoids the risk of overheating because the lower surface of the solar panels is sufficiently clear of the ground to allow cooling by the ambient air. In addition, this system ensures proper orientation of the solar panels in order to better capture solar energy and limit the accumulation of dust on the panels. Moreover, such a fixing facilitates the maintenance and the maintenance of the solar panels which are directly accessible for a technician.

However, this third method of fixing solar panels also has a number of disadvantages.

The inclination of the solar panels causes a strong catch in the wind at the lower surface of the latter, which can lead to untimely tearing said panels. Indeed, it is known that the power of the wind at the level of the roof of buildings is often higher than that present at ground level. There is therefore a significant risk of potential tearing of the solar panels, which poses real problems of efficiency but above all safety. The panels can, indeed, take off and cause serious human and material damage if they hit people and / or vehicles in their fall. B90545 / FR In addition, the means of fixing such solar panels on the roof involve piercing the waterproofness of the roof at multiple locations and thus increase the risk of water infiltration.

Moreover, the direct accessibility of these solar panels on a flat roof can cause risks of electrocution, especially in the case where an unauthorized person would come to touch the electrical conductors direct current cables at the back of the solar panels and whose flow can not be interrupted as long as the photovoltaic panel is irradiated.

Finally, the alignment of the solar panels inclined in rows parallel to each other leads to a significant loss of space because of the necessary presence of sufficient space between the rows to limit the shadow made by a row of solar panels on another row.

The objects assigned to the invention therefore aim to remedy the various drawbacks enumerated above and to propose a new system for supporting photovoltaic panels on a frame which ensures a stable, secure and solid support of said solar panels on the frame.

The present invention relates to a support system 1 of at least one photovoltaic panel 2 on a frame 3. The term "photovoltaic panel" means a photovoltaic solar module, preferably of a geometric shape, able to convert solar energy into electrical energy. received at the level of silicon-based photovoltaic cells. The photovoltaic panel 2 is preferably of substantially parallelepipedal shape (see FIG. 6), with a length substantially comprised between 1.5 and 2.5 m, a width substantially between 0.5 and 1.5 m and a thickness substantially between 1 and 10 cm.

Preferably, the support system 1 constitutes an integrated support system 1 of at least one photovoltaic panel 2 on a substantially flat and substantially horizontal surface of a frame 3, preferably on a substantially flat roof of a building, that is to say whose surface is horizontal or slightly inclined at an angle substantially less than 10 °.

The support system 1 of the present invention comprises a first active holding member 20, which is preferably substantially elongated and which extends between a first and a second end 20A, 20B (see Fig. 5). The first active holding element 20 is designed, on the one hand, to be connected to said photovoltaic panel 2 B90545 / FR as well as to the frame 3, and on the other hand to be put into mechanical tension in order to contribute to maintaining said at least one photovoltaic panel 2 on said frame 3. In other words, the first active holding element 20 is assembled or partially joined with the frame 3 and partly with the photovoltaic panel 2 and participates in the retention and maintenance of the latter on the frame 3. The first holding element 20 is active, that is to say it is not passive in the maintenance of the panel 2. The first active holding element 20 is instead advantageously activatable and plays a dynamic role in maintaining the photovoltaic panel 2, in contrast to the previous holding elements which have a passive role in the maintenance of the photovoltaic panel.

Advantageously, the first active holding element 20 is subjected to a tension force, preferably an extension force, by the action of two substantially opposite tension forces applying and opposing each of the ends 20A. , 20B, said tensioning forces for activating said first active holding element 20. The first active holding element 20 is therefore advantageously taut, substantially rigid and inflexible, in particular under the effect of the mechanical tension forces to which it is subjected, in order to increase the mechanical strength of said support system 1.

Preferably, the first active holding element 20 is a tensioned and tensioned cable, that is to say that it corresponds to an elongated element, tapered or filamentary, of preferentially round section, able to be stretched or elongated by application of a mechanical tension, such as a tensile force for example. Preferably, the first active holding element 20 is made of a material resistant and able to support at least one photovoltaic panel 2, preferably a plurality of photovoltaic panels 2, for example made of steel. However, it is perfectly conceivable that said first active holding element 20 has a section of different geometric shape, for example oval or square, and is made of another material.

Alternatively, it is perfectly conceivable that the attachment to the frame 3 and the tensioning of the first active holding element 20 is at a place other than at its ends 20A, 20B.

This first support element 4 is preferably capable of contributing to the support of at least one photovoltaic panel 2 and is advantageously hollow and has a tubular shape. Preferably, said photovoltaic panel 2 rests at least in part on said support element 4, preferably at a substantially elongated contact surface 4C on which said photovoltaic panel bears (FIGS. 5 and 6).

Advantageously, the first active holding element 20 is inserted into the first support element 4 to which the photovoltaic panel 2 is intended to be attached. As illustrated in FIGS. 1, 4 and 7, the first support element 4 thus advantageously defines an at least partially hollow interior space 4D into which the first holding element is introduced, for example by sliding, molding or interlocking. active means 20 for improving the maintenance of said photovoltaic panel 2 on said frame 2. In other words, the first support member 4 is a tube forming a guide, for example a sliding sleeve, in which is inserted and maintained, preferably in a substantially fixed manner, the cable forming the first active holding element 20. The photovoltaic panel 2 is advantageously fixed, for example by a screw system or by bonding, on the first support means 4 at the contact surface 4C . B90545 / FR Preferably, the first active holding element 20 plays a role of active reinforcement for the support of the photovoltaic panel provided in part by the first support element 4, helping to reduce the risk of tearing of the photovoltaic panel 2. The first active holding element 20 makes it possible in a preferred manner to reduce the risks of resonating or in harmony with the photovoltaic panels 2, in particular in the presence of wind. These two active holding and support elements 4 thus advantageously have a complementary action to allow a stable, effective, safe and durable holding of said photovoltaic panel 2 on the frame 3. It is also perfectly conceivable that only the first active holding element 20 directly supports said photovoltaic panel 2, the first support element 4 then comprising for example simple handles (not shown) in which is inserted said first active holding element 20.

In a particularly advantageous embodiment, the support system 1 of the present invention comprises at least one second active holding element 22, substantially identical to said first active holding element 20, designed to be inserted into a second support element 40, substantially identical to the first support member 4, said second support member 40 extending substantially parallel to said first support member 4 (see Figure 7).

Preferably, the fixing module 5 comprises, advantageously at the level of the wings 5B, 5A, at least one second sealing layer 8 made of a single-component polyurethane resin and intended to cover the first sealing layer 7.

The assembly formed by the screws 6 and the two sealing layers 7, 8 ensures a solid and durable attachment of the fixing module 5 on the frame 3, avoids the risks of tearing of the fixing module 5 and effectively participates in the sealing the frame 3 by forming in particular at least one additional sealing layer. The fastening module 5 allows the support system 1 of the invention to be an integrated system that contributes to the impermeability of the frame 3.

Preferably, said first height H1 is substantially between 10 and 50 cm, preferably substantially between 20 and 30 cm. The fixing module 5 comprises at least one second post 10 designed on the one hand to support said second support element 40 and on the other hand to raise said second support element 40 to a second height H2 of said frame 3. Preferably, said second height H2 is substantially between 60 and 80 cm. The second height H2 of the second post 10 is advantageously substantially different from the first height H1 of the first post 9 so that said photovoltaic panel 2 is substantially inclined. The inclination and the elevation of the photovoltaic panel 2 away from the frame 3 advantageously guarantees the cooling of the rear of said photovoltaic panel 2 in order to avoid the risk of overheating. B90545 / FR Preferably, the two support elements 4, 40 also comprise a contact surface 4C, 40C on which the photovoltaic panel 2 is fixed, such that the difference in height between the posts 9, 10 gives said panel 2 a inclination at an inclination angle of at least 3 °, preferably substantially between 1 and 40 °, preferably between 5 and 30 ° relative to the surface of said frame 3 on which is fixed said support system 4, 40 It is also conceivable that the support system 1 of the invention comprises a support plate 23, for example a support failure, directly fixed on said support elements 4, 40 and able to support said photovoltaic panel 2 at the level of its upper surface 23A which has a shape substantially identical to that of the panel 1.

Preferably, said first and second posts 9, 10 are small posts rising substantially vertically from the upper surface 5D of the inverted U 5 of the fixing module 5. Preferably, said first and second support members 4, 40 rest on respectively the first and the second post 9,10, that is to say that they bear against the upper end 9A, 10A of the latter, so that the main axis of extension said posts 9, 10 is substantially perpendicular to the main axis of extension of said support members 4, 40 and thus holding members 20, 22 inserted without them. In a preferred embodiment, the first attachment module 5 comprises at least one third post 11 substantially identical to the first post 9 and at least one fourth post 12 substantially identical to the second post 10, said third and fourth post 11, 12 contributing to the stable and reliable support of the panel 2.

Preferably, said first and third posts 9, 11 have a height HI substantially less than the height H2 of said second and fourth posts 10, 12, such that said first and second support members 4, 40 extend to heights different, to ensure the inclination of the photovoltaic panel 2 while remaining parallel to the surface of the frame 3. In an advantageous embodiment, the posts 9, 10, 11, 12 have a geometric shape, preferably in the form of a tube made of a material capable of supporting the weight of the photovoltaic panels 2, holding elements 20, 22 and support elements 4, 40, for example of metal such as steel. B90545 / FA 'The support system 1 of the present invention furthermore advantageously comprises means 13 for adjusting the height of each post 9, 10, 11, 12 (see FIGS. a variation of the heights HI and H2 respectively of said posts 9, 11 and 10, 12. The height adjustment means 13 is advantageously composed of a system comprising a first fixed guide 13A and a second movable guide 13B adapted to be set in relative vertical movement with respect to said first fixed guide 13A. Preferably, the guides 13A, 13B have a shape of square tubes, said second movable guide 13B being intended to be movable in the first guide 13A, for example by sliding, so as to vary the height of the corresponding post. The height of the second movable guide 13B in the first fixed guide 13A is advantageously fixed thanks to a rod 13C, of the through-nut type, which is inserted into one of the through orifices 13D (see FIGS. 2 and 3), so as to that the rod 13C passes through said guides 13A and 13B and thus prevents any movement of the second guide 13B in the first guide 13A.

Preferably, each post 9, 10 is fixed to the corresponding support member 4, 40 by means of a hinge 15, which comprises, for example, a hinge 16 (see FIGS. 2 and 3) which is mechanically fixed to the upper end 9A, 10A, 11A, 12A of each post 9, 10, 11, 12. The hinge 14 is preferably formed of a steel frame whose upper plate 16A allows the attachment of the support elements 4, 40, for example by screwing or bolting, as well as a fixing means 16B ensuring the mobility of said hinge 16 relative to the post so as to ensure a surface 16A substantially parallel to the contact surface 4C, 40C of the support elements 4, 40 (see FIGS. 1 and 4), regardless of the angle of inclination of said photovoltaic panel 2.

The posts 9, 10, 11, 12 thus adjustable in height and regularly arranged on the fixing module 5 make it possible to give an optimal slope to the photovoltaic panels 2, to avoid the accumulation of dust on the latter, to reduce the risks of warm up, facilitate their cleaning by precipitation water and ensure a better exposure angle to solar radiation. In addition, the support system 1 allows, thanks to the modularity and adaptability of the posts 9, 10, 11, 12 of the fixing module 8, an individual adjustment of each photovoltaic panel 2 or row of photovoltaic panels 2 so as to limit the effects of the shadow of a row B90545 / FR on another, and thus reduce a loss of space on the frame 3. Indeed, the means 13 for adjusting the height of the posts 9, 10 ensures a adjustment of the panel 2 along a substantially vertical axis relative to the surface of the frame 3 while the articulation 15 of said posts 9, 10 allows adjustment of the panel 2 along an axis substantially horizontal with respect to the surface of the frame 3.

Thus, said at least first and second stakes 9, 10 advantageously form, at least partially, a tilting means and an elevating means of said photovoltaic panel 2, so as to guarantee its functional and efficient positioning on a frame 3.

Preferably, the support system 1 comprises at least a second attachment module 50 substantially identical to the first attachment module 5. In this advantageous embodiment, said first and second support elements 4, 40 are fixed on said first and second second posts 9, 10 respectively of each of said attachment modules 5, 50, so that said first and second attachment modules 5, 50 are interconnected by said first and second support members 4, 40 in which are mechanically tensioned said first and second holding members 20, 22 corresponding (see Figures 5 and 6).

Said first and second fixing modules 5, 50 are advantageously designed to secure at least two photovoltaic panels 2, preferably at least seven or nine photovoltaic panels 2, as shown in FIG. when the photovoltaic panels 2 are oriented in the direction of their length, that is to say substantially horizontally (see FIG. 5), the support system 1 of the invention makes it possible to fix at least seven photovoltaic panels 2 which come in abutment and are attached directly to the support elements 4, 40, which are attached and rest on said posts 9, 10, 11, 12, of at least one fastening module 5, preferably of two fastening modules 5, 10. As shown in FIG. 5, the holding elements 20, 22 are exteriorized of the support elements 4, 40, at the ends 20A, 22A, 20B, 22B of the latter in order to be advantageously secured to the frame. 3 and put in tension, in particular by the adjusting member 21. It is also conceivable that the photovoltaic panels 2 are oriented in the direction of their width, that is to say substantially vertically, on the support elements 4, 40. In this second mode of support, the support system 1 of the invention supports at least nine photovoltaic panels 2, which are directly fixed on the support elements 4, 40 or on the support plate 23 itself. attached to said support members 4, 40. When the photovoltaic panels 2 are fixed vertically, it is also conceivable that the support system 1 comprises side support rails (not shown), forming vertical rails which improves the mechanical strength of the system 1, fixed to the support members 4, 40 forming guides.

In an advantageous embodiment of the present invention, the support system 1 further comprises an electrical cable 30 inserted into said first support element 4 and intended to carry the electric current produced by at least one photovoltaic panel 2. In other words, the electricity produced, preferably in the form of direct current, by said at least one photovoltaic panel 2 is transported inside the support element 4, 40, that is to say in a protected manner and not accessible by the man, in particular to limit the potential risks of electrocution.

As illustrated in Figure 6, it is perfectly conceivable that several support systems 1 as described above are assembled to each other, to create a row 60 of photovoltaic panels 2 (see Figure 6). This embodiment advantageously makes it possible to align a large number of photovoltaic panels 2 on the surface of a frame 3, said support systems 1 then being connected to one another at a junction zone 61. At this zone junction 61, the support elements 4, 40 engage with each other to form a single continuous tube in which a single active holding member 20, 22 corresponding is stretched by attachment and adjustment on the frame 3.

The support system 1 of the invention, thanks to the presence of the active holding elements 20, 22 advantageously allows to withstand strong winds, without the risk of tearing said photovoltaic panels 2. Preferably, this support system 1 ensures a support reliability of said photovoltaic panels without B90545 / FR detachment or tearing for winds corresponding to the wind standard NV65, that is to say for winds of 72km / h for 8h, advantageously for winds corresponding to the standard wind NV110 that is to say for winds of 110km / h for 8h.

Preferably, the support system 1 comprises an electrical network 70, shown diagrammatically in FIG. 8, comprising at least said electrical cable 30 and designed on the one hand to centralize the electric current produced by a group of at least two photovoltaic panels 2 , preferably by at least seven photovoltaic panels 2, supported by said first and second support members 4, 40, and on the other hand to electrically connect said photovoltaic panels to each other.

Advantageously, the electrical network 70 comprises at least one phase electrical wire 71 intended to be inserted continuously into said first support element 4 and at least one positively or negatively charged electrical wire 72 intended to be fixed under said photovoltaic panels 2 and to circulate mainly in said first support element 4, so that said positively or negatively charged electrical wire 72 is in the vicinity of said phase electrical wire 71. Preferably, the cable 30 is therefore advantageously constituted by the fi! electrical phase 71 and at least a portion of the electrical wire positively or negatively charged 72.

Such an electrical configuration makes it possible to place the positively or negatively charged electric wire 72 as close as possible to the phase electrical wire 71 in order to limit the possible electric arcs, which are particularly dangerous. In addition, this configuration makes it possible to limit the risks of electrocution and to protect the electrical cable from the elements.

In addition, the support system 1 of the present invention preferably comprises a sleeve 73 designed to be positioned between two support elements 4 of a first and a second group 62, 63 of photovoltaic panels 2 and to allow the passage of said positively or negatively charged electrical wire 72 of the support element 4 of the first group 62 of photovoltaic panels 2 in the support element 4 of the second group 63 of photovoltaic panels B90545 / FR 2. As illustrated in FIG. 9, said sleeve 73 comprises an opening 74 at which the positively or negatively charged electrical wire 72 is introduced from a photovoltaic panel 2 and two openings 75 which are able to allow the junction between two support elements 4 of two electrical systems. support 1 juxtaposed. The sleeve 73 thus advantageously makes it possible to ensure electrical continuity between all the photovoltaic panels 2 of the same row 60, that is to say of several groups 62, 63 of photovoltaic panels 2.

Furthermore, the sleeve 73, advantageously arranged at the junction zone 61, is designed to ensure continuity of the support of said photovoltaic panels by allowing the stable assembly of two support elements 4 juxtaposed. The sleeve 73 also allows continuity of the holding by allowing a continuous insertion of said active holding element 20 in said support member 4, so as to allow a single tensioning of said active holding member 20 at both ends 60A and 60B of said row of panels 2. In an advantageous embodiment, at least one inverter is positioned at at least one of the ends 60A, 60B of the row 60 of photovoltaic panels 2 to allow the transformation of the continuous electric current. manufactured at the level of the latter in alternating current.

The support system 1 of the invention thus has the advantage of allowing the introduction and the routing of the electrical wiring systems, in particular the electric cable 30, inside the support elements 4, 40 forming support guides of the photovoltaic panels 2, so as to optimize the reduction of the wiring loops, such as electric arcs for example.

The present invention also relates, as such, to a method of installing a support system 1 of at least one photovoltaic panel 2 on a frame 3, which may be in accordance with said support system 1 previously described.

The installation method of the invention also advantageously comprises a step of fixing at least two fastening modules 5, 50 on the surface of the frame 3, using screws 6.
