Description
La présente invention concerne un dispositif d'augmentation de la production d'électricité des panneaux photovoltaïques.The present invention relates to a device for increasing the production of electricity from photovoltaic panels.
La production d'électricité des panneaux photovoltaïques est réduite par 1'échauffement des panneaux photovoltaïques aux heures les plus ensoleillées des jours de fort ensoleillement.The production of electricity from the photovoltaic panels is reduced by the heating of the photovoltaic panels during the sunniest hours of the days of strong sunshine.
Cet échauffement occasionne une baisse du rapport de la quantité d'électricité produite divisée par la quantité de rayonnement solaire incident.This heating causes a drop in the ratio of the amount of electricity produced divided by the amount of incident solar radiation.
Le dispositif selon l'invention permet de remédier à cet inconvénient.The device according to the invention overcomes this drawback.
Il permet de conserver pour le panneau photovoltaïque situé au-dessous de lui une température inférieure à 40°C et de produire une quantité d'électricité plus grande, avec un rayonnement frappant le panneau photovoltaïque réduit, que si le dispositif n' était pas en place.It allows to keep for the photovoltaic panel located below it a temperature lower than 40 ° C and to produce a greater quantity of electricity, with a radiation striking the reduced photovoltaic panel, than if the device was not in square.
Le dispositif est constitué d'un caisson parallélépipédique creux, qui forme l'armature du dispositif, troué en plusieurs endroits sur ses 2 faces les plus grandes, la face supérieure et la face inférieure, selon des lignes et des colonnes, et de lentilles divergentes en verre ou en matière plastique transparente logées chacune à la fois dans un orifice de la face supérieure et dans un orifice de la face inférieure. Les parois du caisson sont en matière thermiquement isolante qui peut être de la matière plastique ou du bois ou un dérivé du bois. Excepté à l'endroit des orifices, où l'on place les lentilles divergentes, les 6 parois du caisson sont opaques et leur revêtement est de couleur blanche ou claire afin de limiter la température du caisson lorsqu'il est exposé aux rayons du soleil.The device consists of a hollow parallelepiped box, which forms the frame of the device, perforated in several places on its 2 largest faces, the upper face and the lower face, according to lines and columns, and divergent lenses made of glass or transparent plastic, each housed both in an orifice on the upper face and in an orifice on the lower face. The walls of the box are made of thermally insulating material which can be plastic or wood or a derivative of wood. Except at the place of the orifices, where the divergent lenses are placed, the 6 walls of the box are opaque and their coating is white or light in color in order to limit the temperature of the box when it is exposed to the rays of the sun.
La paroi de la face supérieure du caisson permet une occultation partielle du rayonnement solaire. La partie du rayonnement solaire qui passe par les lentilles est déviée deux fois, à l'entrée dans les lentilles et à la sortie des lentilles, par réfraction. Le dispositif permet de réduire l'exposition du panneau photovoltaïque aux rayons lumineux solaires tout en assurant que l'ensemble de ce panneau est tout de même éclairé suffisamment et de manière homogène. Le dispositif est utilisable avec un panneau photovoltaïque orientable ou non orientable.The wall of the upper face of the box allows partial concealment of solar radiation. The part of the solar radiation which passes through the lenses is deflected twice, at the entry into the lenses and at the exit of the lenses, by refraction. The device makes it possible to reduce the exposure of the photovoltaic panel to the solar light rays while ensuring that the whole of this panel is nevertheless sufficiently and homogeneously lit. The device can be used with an orientable or non-orientable photovoltaic panel.
À titre d'exemple non limitatif, le caisson de hauteur 20 cm et de largeur et de longueur identiques à celles du panneau photovoltaïque, de 50 cm à plusieurs mètres pour les deux mesures, se place au-dessus du panneau photovoltaïque à une distance de 30 cm de celui-ci.By way of nonlimiting example, the box 20 cm high and identical in width and length to that of the photovoltaic panel, from 50 cm to several meters for the two measurements, is placed above the photovoltaic panel at a distance of 30 cm from it.
L'axe optique des lentilles est perpendiculaire aux plans des faces supérieure et inférieure du caisson de réduction du rayonnement solaire. Les lentilles présentent une surface plus large, qu'elle soit celle d'un disque ou celle d'un rectanqle, du côté de la face inférieure que du côté de la face supérieure afin de permettre l'acheminement d'une plus grande quantité de la lumière solaire incidente pénétrant dans les lentilles. Le dispositif agit comme un atténuateur du rayonnement solaire. Il permet de ne laisser passer qu'une partie du rayonnement solaire et ainsi d'abaisser la température du panneau photovoltaïque. Il ne doit être mis en position au-dessus du panneau photovoltaïque qu'aux heures les plus ensoleillées des jours de fort ensoleillement. Il est donc amovible, que ce soit par un procédé manuel ou grâce à un mécanisme à moteur. La distance laissée entre le panneau photovoltaïque et le caisson de réduction du rayonnement solaire permet de laisser circuler un flux d'air qui rafraîchit le panneau photovoltaïque. Grâce au caisson de réduction du rayonnement solaire, la lumière solaire est d'abord réduite en quantité par la paroi de la face supérieure du caisson, d'environ 65%, et la partie qui passe par les lentilles divergentes, les 35% restants, est ensuite répartie de façon homogène.The optical axis of the lenses is perpendicular to the planes of the upper and lower faces of the solar radiation reduction box. The lenses have a larger surface, whether that of a disc or that of a rectanqle, on the side of the lower face than on the side of the upper face in order to allow the delivery of a greater quantity of incident sunlight entering the lenses. The device acts as an attenuator of solar radiation. It allows only part of the solar radiation to pass and thus lower the temperature of the photovoltaic panel. It should only be positioned above the photovoltaic panel at the sunniest hours on days with strong sunlight. It is therefore removable, either by a manual process or by a motor mechanism. The distance left between the photovoltaic panel and the solar radiation reduction box allows a flow of air to circulate which cools the photovoltaic panel. Thanks to the solar radiation reduction box, the sunlight is first reduced in quantity by the wall of the upper face of the box, by about 65%, and the part which passes through the diverging lenses, the remaining 35%, is then evenly distributed.

La figure 1 représente de face le dispositif de l'invention. La figure 2 représente en coupe le dispositif de l'invention.Figure 1 shows the device of the invention from the front. Figure 2 shows in section the device of the invention.
En référence à ces dessins, le dispositif comporte une armature formée d'un caisson parallélépipédique à 6 faces (1) dont 2, la face supérieure et la face inférieure, sont percées d'orifices circulaires qui accueillent des lentilles divergentes (2) permettant la répartition homogène d'une fraction de la lumière solaire incidente frappant le dispositif.With reference to these drawings, the device comprises a frame formed by a parallelepipedic box with 6 faces (1), 2 of which, the upper face and the lower face, are pierced with circular orifices which accommodate divergent lenses (2) allowing the homogeneous distribution of a fraction of the incident sunlight striking the device.
