Definitions

  • GENERALITY The found is a system of characteristics likely to obtain at least quadruple powers than the panels irradiated directly from the Sun in the same area of photovoltaic panels. As shown in fig. 1 , this is achieved by concentrating solar rays on photovoltaic panels using a series of flat reflective surfaces (2). These surfaces are spread to the larger size to form a one-dimensional parable. This will have focal image of rectangular size. A linear series of photovoltaic sensors (3) will be put to this focal length. These produce energy only if entirely irradiated since the return of these will be limited by sensor made less. Therefore makes necessary chasing the angle of the Sun is in azimuth and elevation.
  • the metallic structure of the parable (see fig.l), has a length of approximately six metres and a height of about a metre, and is designed to minimize resistance to wind and realized with profiles of anodised aluminium that has the characteristic lightness and weather resistance.
  • Mechanical stability can be achieved using curved profile appropriate section connected between them using welded bars.
  • a bar at the Centre of gravity of the structure supports the entire assembly and is supported by bases fasteners that allow its angular motion with minimal friction (see fig. 3). Size and the characteristics of foundations of fasteners, carried out in a similar way to the mechanical structure will be dimensioned by the location of use. Elevation movement is implemented using low-power with gear electric motors.
  • Anchored in the mechanical structure through appropriate media will be placed at the focal length of the parabola a plate of sensors (1). This will also include the coil of copper which will make them cold (8). To effect the pointing described below when the system is running the shadow sensor is always coincident with the central location of the parable which therefore will not be used.
  • PARABOLIC MIRROR The characteristic of the parable is achieved with more reflective surfaces flat fixed along the curved elements of the structure. These surfaces are established by media calibration allow casts rays of the Sun on the focus of the parable where plate (1) is positioned.
  • the width of the reflective surfaces (2) is related to that sensors (3) because the reflected image must be such as to cover them almost entirely width. Their width will be modulated to take account of the different angles of incidence of sunlight.
  • Reflective surfaces that are geared to form the parabolic curve are fixed on curved profile structure using screws calibration (10). To avoid issues constructive mirrors and to simplify its longitudinal calibration, the length of 6 m will be obtained with a series of mirrors (see fig 1) long 1.5 mt.
  • the angle of the mirror in calibration is adjusted by moving the dice (12) until its image is centered on sensors (3). Achieved this result will permanently block the mirror using similar dice (11). It proceeds sequentially for all sets vertical doing care of bringing closer the reflected images on the short side. The precision of the reflected image is less than a millimeter to these mechanical dimensions.
  • This calibration in production may be simplified or perhaps omitted.
  • the difference in length between the parable (4) and sensor (3) is the most significant characteristic of the found as it allows the system to accept a wide azimuth (greater than 90 degrees).
  • the fig. 6 shows the condition of the morning when the sun comes to the minimum useful azimuth (5) and sensors (3) are irradiated evenly from rays reflected from the surface (4), and thus began the production of electricity.
  • FOTOVOLTAIC SENSORS photovoltaic cells that can be used by the found are of any type (crystalline uni-poli and others) and in sufficient number for an economic energy transfer.
  • the one- dimensional with elements around 12 Cm side array is a possible form for the found that allows a low resistance to wind and a large number of reflections. This allows you to have a high gain with a contained surface compared to direct lighting systems.
  • SYSTEM OF POINTING the found allows all sensors are illuminated when the azimuth is between the minimum and maximum allowed (9) (as seen in the parabolic mirror section). It is therefore sufficient pointing system to change the elevation of the structure for the pursuit of the Sun on both axes during the day.
  • the reflected image from mirrors is less than the width of the sensors (3), there is a margin of tolerance in the pointing in elevation.
  • the error pointing is highlighted by two detectors (14) seats on either side of the plate midpoints and a dedicated circuit will make turn an engine that moves in the right direction structure elevation axis pointing; this movement will be maintained for a minimum time beyond the indispensable to prevent instability to the structure with consequent waste of energy.
  • the system chases the angle of elevation of the Sun in his daily reaching maximum during the day and falling gradually until the evening when, reached the maximum azimuth evolution (20), energy received from the sensors will be almost nothing and the pointing will be disabled.
  • Non-powered engine works as a brake to prevent unwanted movements due to wind.
  • INVERTER This device converts line very low voltage sensors in low voltage AC. This line must be the shortest possible because it is to produce the greatest losses, therefore the inverter is placed in the immediate vicinity of the structure.
  • the global testing can be easily entrusted to a remote display in which perform all checks including those of the efficiency of the system. From these tests, you can extrapolate alerts on any malfunction. If the system was part of a greater system (see fig 2), a single remote control might all constituents systems. THERMAL GROUP the found requires a piece of unused mirror for all sensors are always irradiated without making angular movements in azimuth.
  • thermal converters (7) in the plate (1) with the objective of collecting energy be used as a source of heat for example household.
  • Unlike PV thermal energy does not require the full irradiation and can be accumulated in a boiler during the day and used for example to household. It also highlights that the heat by deriving from one system to mirrors may reach high temperatures in the cold months. With reference to fig. 5, when the temperature of the plate (1) is lower than that of sensors, to increase the efficiency of the latter, through a pump coil (9) coolant is circulated in a radiator.

Abstract

L'invention porte sur un système dont les caractéristiques sont susceptibles de permettre d'obtenir des puissances au moins quadruples de celles des panneaux directement exposés au soleil avec la même surface de panneaux photovoltaïques ; ceci est obtenu en concentrant les rayons solaires sur des panneaux photovoltaïques à l'aide d'une série de surfaces réfléchissantes plates. Ces surfaces sont étalées en une plus grande dimension pour former une parabole monodimensionnelle. Celle-ci aura une image focale de forme rectangulaire. Une série linéaire de capteurs photovoltaïques sera placée à cette distance focale. Ceux-ci produisent de l'énergie uniquement s'ils sont entièrement exposés étant donné que leur rendement sera limité par l'amoindrissement des capteurs. Il est donc nécessaire de poursuivre l'angle du soleil en azimut et en élévation. L'invention permet d'obtenir ce résultat à l'aide d'un seul mouvement physique (élévation), un autre (azimut) étant obtenu à l'aide d'une forme appropriée des surfaces réfléchissantes. Les mêmes résultats que ceux d'un système classique sont obtenus en utilisant une surface de captage de plus de 20 % de rayons, mais une réduction par cinq de la surface photovoltaïque requise permet d'obtenir le résultat à moindre coût. Les matières premières nécessaires pour réaliser un captage à grande échelle sont également simples.
