Description

Support traqueur pour panneau solaire  Tracker support for solar panel
La présente invention se rapporte à un support traqueur pour panneau solaire. The present invention relates to a tracking support for solar panel.
Afin d'optimiser le rendement électrique de panneaux solaires, ces dern iers sont généralement équ ipés de système de pou rsu ite sola ire permettant de modifier leur orientation en fonction de la course du soleil de manière à maximiser la captation de lumière par ledit panneau.  In order to optimize the electrical efficiency of solar panels, the latter are generally equipped with a solitary lighting system that makes it possible to modify their orientation as a function of the path of the sun so as to maximize the light pickup by said panel.
En effet, le rendement d'un panneau solaire est maximal lorsque le rayonnement solaire a une incidence sensiblement perpendiculaire au panneau.  Indeed, the efficiency of a solar panel is maximum when the solar radiation has an impact substantially perpendicular to the panel.
Afin de pouvoir conserver au mieux cette orientation en fonction de la course du soleil sur l'horizon tout au long d'une journée, les panneaux solaires sont installés sur des supports suiveurs présentant un ou plusieurs axes d'articulation permettant l'orientation du panneau selon une ou plusieurs direction grâce à un ou plusieurs moteurs.  In order to better preserve this orientation according to the sun's path on the horizon throughout a day, the solar panels are installed on the follower supports having one or more axes of articulation allowing the orientation of the panel in one or more directions with one or more engines.
On distingue notamment les supports suiveurs à un ou deux axes d'articulation.  In particular, the follower supports have one or two axes of articulation.
Les supports suiveurs deux axes permettent un suivi du soleil selon son azimut et son élévation.  The two-axis tracking supports allow the sun to be tracked according to its azimuth and elevation.
Dans les régions du globe terrestre où la course du soleil varie peu en hauteur par rapport à l'horizon, un support suiveur à un axe pourra être suffisant.  In areas of the earth where the sun's path varies slightly in height from the horizon, a single-axis tracking support may be sufficient.
Les supports suiveurs un axe permettent un suivi du soleil par rotation autour d'un axe fixe.  The follower supports an axis allow a tracking of the sun by rotation around a fixed axis.
Selon un premier mode de réalisation connu, l'axe de rotation est sensiblement vertical. Un tel support suiveur comprend généralement un pied central ancré dans un bloc en béton, au sommet duquel est installé le panneau solaire mobile en rotation autour de l'axe du pied central. Un moteur piloté assure l'entraînement en rotation.  According to a first known embodiment, the axis of rotation is substantially vertical. Such a follower support generally comprises a central foot anchored in a concrete block, at the top of which is installed the rotating solar panel rotating about the axis of the central foot. A controlled motor ensures the drive in rotation.
Cette rotation autour du pied central permet un suivi de en azimut sur environ 270° en général.  This rotation around the central foot allows tracking in azimuth about 270 ° in general.
On notera que le panneau solaire est installé de manière inclinée par rapport au sol correspondant à une élévation du soleil entre 5 et 75 degrés. Cette inclinaison peut généralement être réglée manuellement en fonction de la saison et de l'élévation moyenne correspondante du soleil sur la plus grande partie de la journée. Toutefois, la rotation s'effectuant autour d'un axe vertical, l'inclinaison du panneau ne permet pas de prendre en compte l'élévation du soleil en début et fin de journée. It should be noted that the solar panel is installed in an inclined manner with respect to the ground corresponding to a rise of the sun between 5 and 75 degrees. This inclination can usually be adjusted manually according to the season and the corresponding average elevation of the sun on the largest part of the day. However, the rotation is performed around a vertical axis, the inclination of the panel does not take into account the rise of the sun at the beginning and end of the day.
Un support suiveur à deux axes comprendra également un pied central vertical constituant un axe de rotation du panneau, et un support motorisé permettant d'en faire varier l'inclinaison au sommet du pied central. Le panneau pourra alors également assurer un suivi du soleil selon son élévation.  A two-axis follower support will also comprise a vertical central foot constituting an axis of rotation of the panel, and a motorized support for varying the inclination at the top of the central foot. The panel will then also be able to follow the sun according to its elevation.
Selon un deuxième mode de réalisation connu, l'axe de rotation correspond sensiblement à l'axe médian du panneau.  According to a second known embodiment, the axis of rotation substantially corresponds to the median axis of the panel.
Dans une première variante, l'axe de rotation est sensiblement horizontal. Le panneau peut alors effectuer un suivi en élévation mais est fixe en azimut. Le support comprend alors deux pieds latéraux d'extrém ité définissant un axe sensiblement horizontal sur lequel le panneau solaire est monté en rotation à l'aide de fourches support.  In a first variant, the axis of rotation is substantially horizontal. The panel can then follow in elevation but is fixed in azimuth. The support then comprises two lateral feet of extremity defining a substantially horizontal axis on which the solar panel is rotatably mounted with support forks.
Dans une seconde variante optimisée, l'axe de rotation est lui- même incliné.  In a second optimized variant, the axis of rotation is itself inclined.
Cette technique permet un moins bon suivi en azimut qu'une rotation autour d'un pied central vertical, mais un meilleur suivi en élévation au cours d'une journée.  This technique allows a less good azimuth tracking than a rotation around a vertical central foot, but a better follow-up in elevation during a day.
Un tel support suiveur comprend généralement trois pieds formant une base triangulaire supportant une armature sensiblement pyramidale. Un pied bas situé au niveau d'un sommet de la base triangulaire forme, avec le sommet élevé de la pyramide, l'axe de support et de rotation du panneau solaire. Un exemple de tel support est décrit dans le document DE 20 2004 001 642.  Such a follower support generally comprises three legs forming a triangular base supporting a substantially pyramidal frame. A low foot located at a vertex of the triangular base forms, with the high peak of the pyramid, the axis of support and rotation of the solar panel. An example of such support is described in DE 2004 001 642.
Un tel support occupe toutefois une place importante au sol, et présente donc un encombrement non négligeable. Par ailleurs, son installation nécessite la pose de trois pieds, généralement en béton, et il n'est pas aisément ré-implantable à un autre endroit si nécessaire.  Such a support however occupies an important place on the ground, and therefore has a significant footprint. In addition, its installation requires the installation of three feet, usually concrete, and it is not easily re-implantable to another place if necessary.
II existe donc un besoin pour un support suiveur à un axe ne présentant pas les inconvénients précédemment mentionnés.  There is therefore a need for a follower support axis that does not have the disadvantages mentioned above.
Pour ce faire, la présente invention se rapporte à un support suiveur à un axe pour panneau solaire, comprenant un pied central sensiblement vertical, caractérisé en ce que le pied central est prolongé par au moins deux crosses s'étendant de part et d'autre dud it pied central et présentant chacune une extrémité définissant ensemble un axe de rotation du panneau solaire, chaque extrémité étant équipée d'au moins un moyen de montage rotatif dudit panneau. To do this, the present invention relates to a single-axis follower support for solar panel, comprising a substantially vertical central foot, characterized in that the central foot is extended by at least two brackets extending on either side dud it central foot and each having an end together defining an axis of rotation of the solar panel, each end being equipped with at least one rotatable mounting means of said panel.
Ainsi, grâce à un pied unique à partir duquel se déploie une fourche support, l'espace d'implantation au sol est considérablement réduit tout en conservant les propriétés de suivi solaire recherchée. L'implantation de ce support en est également grandement facilitée. Par ailleurs, l'orientation des crosses par rapport à l'horizon est orientable..  Thus, thanks to a single foot from which deploys a support fork, the ground implantation space is considerably reduced while maintaining the solar tracking properties sought. The implementation of this support is also greatly facilitated. Moreover, the orientation of the sticks with respect to the horizon is orientable ..
De manière préférentielle, le pied central se présente sous la forme d'un fourreau à l'intérieur duquel sont maintenues des deux crosses.  Preferably, the central foot is in the form of a sleeve inside which are held two sticks.
Avantageusement, la hauteur relative des crosses est réglable, de manière à modifier l'inclinaison de l'axe de rotation du panneau.  Advantageously, the relative height of the brackets is adjustable, so as to change the inclination of the axis of rotation of the panel.
Avantageusement encore, le réglage de la hauteur relative des crosses est motorisé. Le support peut alors se transformer en support traqueur à deux axes.  Advantageously, the adjustment of the relative height of the sticks is motorized. The support can then be transformed into a two-axis tracker carrier.
De manière préférentielle, les moyens de montage rotatif du panneau sont associés à au moins un moyen d'entraînement correspondant.  Preferably, the rotary mounting means of the panel are associated with at least one corresponding drive means.
Avantageusement, le moyen d'entraînement comprend au moins un moteur.  Advantageously, the drive means comprises at least one motor.
Avantageusement encore, le moyen d'entraînement comprend au moins un câble. Ainsi, un ensemble de panneaux peut être entraîné à l'aide du même câble et du même moteur.  Advantageously, the drive means comprises at least one cable. Thus, a set of panels can be driven using the same cable and the same motor.
La présente invention se rapporte également à une installation photovoltaïque comprenant au moins un panneau solaire installé sur au moins un support correspondant selon l'invention.  The present invention also relates to a photovoltaic installation comprising at least one solar panel installed on at least one corresponding support according to the invention.
Avantageusement, le moyen d'entraînement est commu n à plusieurs ensembles panneau solaire / support.  Advantageously, the drive means is shared by several solar panel / support assemblies.
La présente invention sera mieux comprise à la lumière de la description détaillée qui suit en regard du dessin annexé dans lequel :  The present invention will be better understood in the light of the following detailed description with reference to the appended drawing in which:
- la figure 1 est une représentation schématique en perspective de côté d'un panneau solaire et d'un support de panneau selon l'invention.  - Figure 1 is a schematic side perspective view of a solar panel and a panel support according to the invention.
- la figure 2 est une représentation du panneau et support de la figure 1 vu de l'autre côté.  - Figure 2 is a representation of the panel and support of Figure 1 seen from the other side.
- la figure 3 est une représentation schématique du support selon l'invention seul.  - Figure 3 is a schematic representation of the support according to the invention alone.
- la figure 4 est une représentation schématique simplifiée d'une installation photovoltaïque comprenant une pluralité de panneaux solaires disposés chacun sur un support selon l'invention et entraînés par un câble unique. FIG. 4 is a simplified schematic representation of a photovoltaic installation comprising a plurality of solar panels each arranged on a support according to the invention and driven by a single cable.
Les figures 1 et 2 montrent un ensemble photovoltaïque 10 comprenant un support 1 supportant un panneau solaire 2. Figures 1 and 2 show a photovoltaic assembly 10 comprising a support 1 supporting a solar panel 2.
Le support 1 est représenté seul à la figure 3.  The support 1 is shown alone in FIG.
Conformément à l'invention, le support 1 est un support traqueur à un axe pour le panneau solaire 2, c'est-à-dire apte à permettre l'orientation du panneau solaire 2 par pivotement autour d'un axe de rotation R.  According to the invention, the support 1 is a single-axis tracker for the solar panel 2, that is to say capable of allowing the orientation of the solar panel 2 by pivoting about an axis of rotation R.
Pour ce faire, le support 1 est réalisé à partir d'un pied 3 apte à permettre l'ancrage du support 1 dans le sol, ledit pied 3 formant un fourreau recevant deux crosses 4, 5 destiné à permettre l'installation du panneau solaire 2.  To do this, the support 1 is made from a foot 3 adapted to allow the anchoring of the support 1 in the ground, said foot 3 forming a sleeve receiving two brackets 4, 5 to allow the installation of the solar panel 2.
Les deux crosses 4 et 5 s'étendent depuis le pied 3 et sont recourbées de part et d'autre dudit pied 3 central. Elles présentent chacune une extrémité 4a, 5a définissant ensemble un axe de rotation du panneau solaire 2, chaque extrémité étant équipée d'au moins un moyen de montage rotatif dudit panneau.  The two sticks 4 and 5 extend from the foot 3 and are curved on either side of said central foot 3. They each have an end 4a, 5a together defining an axis of rotation of the solar panel 2, each end being provided with at least one rotary mounting means of said panel.
Une différence de hauteur entre la crosse 4 et la crosse 5 assure l'inclinaison de l'axe de rotation R, et par voie de conséquence du panneau solaire 2 monté sur le support. En l'espèce, l'exemple représenté montre une inclinaison d'environ 20 degrés par rapport au sol.  A difference in height between the butt 4 and the butt 5 ensures the inclination of the axis of rotation R, and consequently of the solar panel 2 mounted on the support. In this case, the example shown shows an inclination of about 20 degrees relative to the ground.
Avantageusement, la différence de hauteur est réglable, notamment par réglage d'au moins une crosse à l'intérieur du pied 3 fourreau.  Advantageously, the difference in height is adjustable, in particular by adjusting at least one butt inside the foot 3 sleeve.
Comme visible sur la figue 2, le panneau solaire 2 est installé sur son support 1 par l'intermédiaire de fourches d'extrémités 6 montées en rotation sur les extrémités 4a, 5a de montage des deux crosses. Pour ce faire, les fourches 6 pourront présente un embout introduit sur chacune des extrémités 4a, 5a.  As shown in Fig 2, the solar panel 2 is installed on its support 1 by means of end forks 6 rotatably mounted on the ends 4a, 5a mounting the two sticks. To do this, the forks 6 may have a tip inserted on each of the ends 4a, 5a.
Afin de pouvoir être piloté en fonction de la course du soleil, chaque installation photovoltaïque 10 est associé à des moyens d'entraînement aptes à permettre l'entraînement du panneau solaire 2 en rotation autour de son axe R.  In order to be able to be controlled as a function of the solar path, each photovoltaic installation 10 is associated with drive means capable of enabling the solar panel 2 to be driven in rotation about its axis R.
Bien, évidemment, on connaît les moyens d'entraînement habituels, qui restent applicables. Avec les solutions actuelles, chaque installation 10 doit toutefois être équipée de ses propres moyens d'entraînement. Well, of course, we know the usual training means, which remain applicable. With the current solutions, each installation 10 must however be equipped with its own means of training.
Selon un aspect complémentaire de l'invention, les moyens d'entraînement sont communs à plusieurs panneaux solaires 2.  According to a complementary aspect of the invention, the drive means are common to several solar panels 2.
La figure 4 montre un exemple de réalisation.  Figure 4 shows an exemplary embodiment.
La figure 4 présente un ensemble d'installations photovoltaïques 10 selon l'invention. Ces installations sont alignées pour former une rangée de panneaux solaires 2 et support traqueur 1 .  FIG. 4 presents a set of photovoltaic installations 10 according to the invention. These installations are aligned to form a row of solar panels 2 and tracker support 1.
Chaque panneau solaire 2 est équipé d'un bras 7 s'étendant sensiblement perpendiculairement au panneau solaire 2 et de part et d'autre de ce dernier.  Each solar panel 2 is equipped with an arm 7 extending substantially perpendicular to the solar panel 2 and on both sides of the latter.
Un câble de traction 8 parcourt la rangée de panneaux solaires 2, chaque point haut du bras 7 de chaque panneau solaire 2 étant fixé au câble de traction 8.  A traction cable 8 traverses the row of solar panels 2, each high point of the arm 7 of each solar panel 2 being fixed to the traction cable 8.
Le câble de traction 8 réalise une boucle et chaque point bas du bras 7 de chaque panneau solaire 2 est également fixé au câble de traction 8.  The traction cable 8 carries a loop and each low point of the arm 7 of each solar panel 2 is also fixed to the traction cable 8.
Ainsi, en tirant sur le câble de traction 8 d'un côté ou de l'autre, il est possible d'entraîner en pivotement uniformément toute la rangée de panneaux solaires 2.  Thus, by pulling on the traction cable 8 on one side or the other, it is possible to pivotably drive the entire row of solar panels 2.
L'entraînement du câble de traction 8 s'effectue quant à lui par un motoréducteur 1 1 d'extrémité, monté sur un pylône 12 d'entraînement.  The driving of the traction cable 8 is carried out by a geared motor 1 1 end, mounted on a pylon 12 drive.
A l'autre extrémité de la rangée est située un deuxième pylône 13 assurant le rôle de tête de tension, et possédant des moyens permettant de garder le câble de traction 8 suffisamment tendu, notamment par l'intermédiaire d'un bras de tension.  At the other end of the row is located a second pylon 13 acting as a voltage head, and having means for keeping the traction cable 8 sufficiently taut, in particular via a tension arm.
Bien évidemment, avec des systèmes de poulies et de renvois adéquats, le câble de traction 8 pourra éventuellement être mutualisé entre plusieurs rangées d'installation photovoltaïques 10.  Of course, with suitable pulley and return systems, the traction cable 8 may possibly be shared between several rows of photovoltaic installations 10.
Bien que l'invention ait été décrite avec un exemple particulier de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.  Although the invention has been described with a particular embodiment, it is obvious that it is in no way limited and that it includes all the technical equivalents of the means described and their combinations if they enter into the scope of the invention.
