Description

Support suiveur pour panneau solaire  Follow-up support for solar panel
La présente invention se rapporte à un support traqueur à un axe pour panneau solaire. The present invention relates to a one-axis tracker carrier for solar panel.
Afin d'optimiser le rendement électrique de panneaux solaires, ces derniers sont généralement installés sur des supports équipés de système de poursuite solaire 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 performance of solar panels, they are generally installed on supports equipped with solar tracking system to change their orientation according to the solar path so as to maximize the light capture by said panel.
En effet, le rendement d'un panneau solaire est maximal lorsque le rayonnement solaire a une incidence sensiblement perpend iculaire 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 directions 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 manually adjusted according to the season and the corresponding average rise of the sun over most 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.
Bien évidemment, de tels suiveurs un axe peuvent également être util isés dans des régions du globe où la variation d'élévation du soleil en fonction des saisons est plus importante. Par exemple, sous les latitudes françaises, l'élévation du soleil à midi varie de 18° à 62° aux deux solstices. L'util isation d 'un support su iveur à un axe incl iné permettra alors une inclinaison optimale en fonction, notamment, du facteur d'ombrage mutuel des suiveurs, de la saisonnalité de l'ensoleillement, réfraction de la lumière dans l'épaisseur des panneaux ainsi que rendement surfacique du terrain occupé par la centrale solaire, entre autres paramètres possibles.  Of course, such an axis followers may also be used in regions of the world where the variation in sun rise with the seasons is greater. For example, in the French latitudes, the rise of the sun at noon varies from 18 ° to 62 ° at the two solstices. The use of a heavy support on an inclined axis will then allow an optimal inclination according to, inter alia, the mutual shading factor of the followers, the seasonality of the sunshine, refraction of the light in the thickness panels as well as surface yield of the land occupied by the solar power plant, among other possible parameters.
En fonction de la disparité de l'ensoleillement au cours de l'année, une centrale à support suiveur à un axe judicieusement incliné pourra garantir un rendement annuel très proche d'une centrale à suiveurs à deux axes.  Depending on the disparity of sunshine during the year, a well-inclined center with a follower support system can guarantee an annual yield very close to a two-axis tracking plant.
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'extrémité 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 end feet 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 panel solar. 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.
De manière générale ces supports sont encombrants à transporter et nécessite un temps de montage non négligeable.  In general, these supports are bulky to carry and requires a significant installation time.
Une solution permettant de facil iter le transport et simplifier l'installation est décrite dans le document EP 2 339 262.  A solution for facilitating transport and simplifying the installation is described in document EP 2 339 262.
Ce document ne résout toutefois pas le problème de l'entraînement et de l'orientation des panneaux.  This document, however, does not solve the problem of training and orientation of the panels.
La présente invention vise à fournir un support traqueur à un axe pour panneaux solaires présentant un volume de stockage et de transport réduit et un temps de montage sur site optimisé tout en possédant un système d'orientation simplifié.  It is an object of the present invention to provide an axis tracker carrier for solar panels having a reduced storage and transport volume and an optimized on-site mounting time while having a simplified orientation system.
Pour ce faire, la présente invention se rapporte à une installation photovoltaïque comprenant au moins deux panneaux solaires installés sur au moins un support suiveur à un axe comprenant un châssis formant une base sensiblement trapézoïdale présentant au moins deux côtés opposés sensiblement parallèles entre eux, ledit châssis étant équ ipé de cadres supports repliables sensiblement parallèles entre eux et destiné chacun à recevoir un panneau solaire, lesdits cadres support comprenant chacun deux pieds d'extrémité aptes à recevoir un panneau solaire et définissant ensemble un axe de rotation dudit panneau, lesdits pieds d'extrémité étant montés sur les côtés parallèles du châssis de manière repliables, caractérisée en ce que chaque panneau est associé à au moins un moyen d'entraînement en rotation actionné par au moins un câble de traction.  To do this, the present invention relates to a photovoltaic installation comprising at least two solar panels installed on at least one axis follower support comprising a frame forming a substantially trapezoidal base having at least two opposite sides substantially parallel to each other, said frame being equ ipé of foldable support frames substantially parallel to each other and each intended to receive a solar panel, said support frames each comprising two end feet adapted to receive a solar panel and together defining an axis of rotation of said panel, said feet of end being mounted on the parallel sides of the frame foldably, characterized in that each panel is associated with at least one rotary drive means actuated by at least one traction cable.
Ainsi, grâce à la mise en œuvre de pieds et cadres supports repl iables, le support traqueur peut être transporté sur site à plat avant installation des panneaux solaires. Le transport et stockage du support traqueur en est grandement facilité. Par ailleurs, l'installation en est d'autant plus aisée, que les cadres supports peuvent être simplement déployés sans avoir à être assemblés et montés sur site. En outre, grâce à son moyen d'entraînement et d'orientation par câble, on dispose d'un système efficace et simple. Ce type de support permet en outre une bonne répartition des charges de la traction par câble. Thus, thanks to the implementation of feet and collapsible support frames, the tracker support can be transported on site flat before installation of the solar panels. Transport and storage of tracker support is greatly facilitated. Moreover, the installation is all the easier, the support frames can be simply deployed without having to be assembled and mounted on site. In addition, thanks to its means of drive and orientation by cable, there is an efficient and simple system. This type of support also allows a good distribution of the loads of the cable traction.
Avantageusement, les pieds sont repliables le long des côtés parallèles du châssis sur lesquels ils sont montés.  Advantageously, the feet are foldable along the parallel sides of the frame on which they are mounted.
De manière préférentielle, les pieds sont associés à des béquilles de maintien en position dépliée.  Preferably, the feet are associated with holding crutches in the unfolded position.
Avantageusement, les pieds d'extrémité sont par ailleurs liés par une barre transversale apte à recevoir le panneau solaire.  Advantageously, the end legs are also connected by a transverse bar adapted to receive the solar panel.
Alternativement ou de man ière com pl émenta ire, les pieds d'extrémité sont terminés par des fourches support conçues pour recevoir un panneau solaire.  Alternatively or in a complementary manner, the end legs are terminated by support forks designed to receive a solar panel.
Selon une première variante de réalisation, l'axe de rotation défini par les pieds d'extrémité est sensiblement horizontal. Le panneau peut alors effectuer un suivi en élévation mais est fixe en azimut.  According to a first variant embodiment, the axis of rotation defined by the end legs is substantially horizontal. The panel can then follow in elevation but is fixed in azimuth.
Selon une deuxième variante de réalisation, l'axe de rotation défini par les pieds d'extrémité est incliné. 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.  According to a second variant embodiment, the axis of rotation defined by the end legs is inclined. 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.
Préférentiel lement, que la hauteu r des pieds est rég lable, avantageusement, de manière indépendante.  Preferably, the height of the feet is reg lable, advantageously, independently.
Selon un mode préféré de réalisation, le châssis forme un parallélogramme, notamment un rectangle.  According to a preferred embodiment, the chassis forms a parallelogram, in particular a rectangle.
De manière préférentielle, les moyens d'entraînement en rotation sont communs aux panneaux du support. Plus précisément, le câble de traction est commun à plusieurs supports.  Preferably, the rotation drive means are common to the support panels. More specifically, the traction cable is common to several supports.
Avantageusement, les moyens d'entraînement comprennent une barre de liaison.  Advantageously, the drive means comprise a connecting bar.
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:

Conformément à l'invention, le support suiveur 3 présente un châssis 31 rectangulaire dans les angles sont fixés dans des pieds en bétons 32 ancrés dans le sol.  According to the invention, the follower support 3 has a rectangular frame 31 in the corners are fixed in concrete feet 32 anchored in the ground.
Le châssis 31 forme une base présentant deux grands côtés parallèles entre eux, et deux petits côtés parallèles en eux (forme rectangulaire).  The frame 31 forms a base having two long sides parallel to each other, and two small parallel sides in them (rectangular shape).
Le châssis 31 est équipé au niveau de ses deux petits côtés, de deux cadres supports 33 sensiblement parallèles entre eux et supportant chacun un panneau solaire 2.  The frame 31 is equipped at its two small sides, two support frames 33 substantially parallel to each other and each supporting a solar panel 2.
Pour ce faire, chaque cadre support 33 comprend deux pieds d'extrémité 331 , 332 définissant ensemble un axe de rotation dudit panneau solaire 2 et matérialisé par une barre transversale 333 supportant de manière rotative le panneau solaire 2.  To do this, each support frame 33 comprises two end legs 331, 332 together defining an axis of rotation of said solar panel 2 and materialized by a transverse bar 333 rotatably supporting the solar panel 2.
Selon une caractéristique innovante de l'invention, les pieds d'extrémité 331 , 332 sont montés repliables sur le châssis 231 .  According to an innovative feature of the invention, the end legs 331, 332 are foldably mounted on the frame 231.
Plus précisément, les pieds 331 , 332 sont repliables le long des grands côtés parallèles du châssis 31 sur lesquels ils sont montés.  Specifically, the feet 331, 332 are foldable along the long parallel sides of the frame 31 on which they are mounted.
Les cadres supports 33 sont maintenus dépliés à l'aide de béquilles 35. Il est également possible de prévoir une barre transversale 36 de renfort en bas des pieds 331 , 332.  The support frames 33 are held unfolded using stands 35. It is also possible to provide a transverse reinforcement bar 36 at the bottom of the feet 331, 332.
Les figures 3 à 5 montrent les étapes de dépliages et installation du support suiveur 31 avant de recevoir les panneaux solaires 2.  Figures 3 to 5 show the steps of unfolding and installation of the follower support 31 before receiving the solar panels 2.
En l'espèce, il convient de noter que la barre 333 définit un axe de rotation incliné.  In this case, it should be noted that the bar 333 defines an inclined axis of rotation.
Avantageusement, la hauteur relative des pieds 331 , 332, et donc l'incl inaison de l'axe de rotation, peut être réglable. On pourra notamment prévoir des pieds télescopiques.  Advantageously, the relative height of the feet 331, 332, and therefore the inclination of the axis of rotation, can be adjustable. It may include telescopic legs.
L'installation photovoltaïque 1 comprend en outre des moyens d'entraînement en rotation des panneaux solaires 2 afin de pouvoir être pilotée en fonction de la course du soleil.  The photovoltaic installation 1 further comprises means for rotating the solar panels 2 so that it can be controlled according to the solar path.
Bien, évidemment, on connaît les moyens d'entraînement habituels, qui restent applicables. Avec les solutions actuelles, chaque installation est toutefois généralement équipée de ses propres moyens d'entraînement. Well, of course, we know the usual training means, which remain applicable. With the current solutions, each However, the installation is generally equipped with its own means of training.
En l'espèce, chaque panneau 2 est équipé d'un bras d'entraînement 40, les deux bras d'entraînement étant par ailleurs reliés entre eux par une barre de liaison 50. Ainsi, l'entraînement en rotation des panneaux solaires 2 est commun.  In this case, each panel 2 is equipped with a drive arm 40, the two drive arms being furthermore interconnected by a connecting bar 50. Thus, the rotation drive of the solar panels 2 is common.
L'entraînement pourra notamment se faire par câble de traction, notamment par l'intermédiaire d'autres installations voisines, la barre de liaison 50 renvoyant le mouvement à l'installation voisine par l'intermédiaire dudit câble de traction.  The drive may in particular be done by traction cable, in particular through other neighboring facilities, the connecting bar 50 returning the movement to the neighboring facility via said traction cable.
On pourra également prévoir que câble de traction réalise une boucle et que chaque barre de liaison 50 est également fixée au câble de traction. Ainsi, en tirant sur le câble de traction d'un côté ou de l'autre, il est poss ible d'entraîner en pivotement u n iformément toute une rangée d'installation selon l'invention.  It can also be provided that the traction cable performs a loop and that each connecting bar 50 is also attached to the traction cable. Thus, by pulling the pulling cable from one side or the other, it is possible to pivotably drive a whole row of installations according to the invention.
L'entraînement du câble de traction pourra s'effectuer quant à lui par un motoréducteur d'extrémité, monté sur un pylône d'entraînement.  The traction cable drive can be performed by an end gear motor, mounted on a drive tower.
A l'autre extrémité de la rangée est située un deuxième pylône assurant le rôle de tête de tension, et possédant des moyens permettant de garder le câble de traction suffisamment tendu, notamment par l'intermédiaire d'un bras de tension.  At the other end of the row is located a second tower acting as a voltage head, and having means for keeping the pulling cable sufficiently taut, especially via a tension arm.
Bien évidemment, avec des systèmes de poulies et de renvois adéquats, le câble de traction pourra éventuellement être mutualisé entre plusieurs rangées d'installation photovoltaïques.  Of course, with suitable pulley and return systems, the traction cable could possibly be shared between several rows of photovoltaic installations.
Bien que l'invention ait été décrite avec un exemple particulier de réal isation, 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 example of real isation, 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 in the context of the invention.
