Description

  The present invention relates to a concentrating solar power generation panel, in particular, a configuration excellent in alignment of the mounting position of the panel to the tracking frame, a method of assembling the panel to the tracking frame, and a tracking type solar panel using the panel The present invention relates to a photovoltaic device and an instrument used for the alignment.

The photovoltaic power generation panel is a flat rectangular parallelepiped concave housing that is surrounded by a side plate around the entire periphery of a rectangular bottom plate, a translucent plate provided in an opening of the housing, and provided in the housing through the translucent plate. In general, a configuration including a power generation element that converts sunlight into electricity is common.
The photovoltaic power generation panel having this configuration includes a flat plate type in which a large number of power generation elements (cells) are arranged adjacent to each other in a plane, and the power generation elements are directly irradiated with sunlight to generate power, and the light transmitting plate. As a condensing lens plate such as a Fresnel lens, there is a condensing type that condenses sunlight with the lens and irradiates the power generation element to concentrate solar energy to generate electric power.
In addition, the solar power generation panel installation mode (solar power generation device) includes a fixed type that is fixed to a roof or the like, and a tracking type that is installed on a rack that tracks the sun (tracking date). Since the condensing position shifts at the position of the sun, the solar power generation panel is always in the tracking type so that the sun always wants the sun (direct light is orthogonal) (see Patent Document 1 FIG. 1 and Patent Document 2 FIG. 1). .

  By the way, sunlight falls on the earth with the sunrise, but as shown by the chain line in FIG. 7, since the direct light does not hit straight from the sunrise and enters the fixed type photovoltaic power generation panel at an angle. Rises gradually from sunrise, peaks at near noon, and gradually decreases toward the sunset. On the other hand, as shown by the solid line in the figure, a tracking solar power generation panel In order to face the sun, direct light hits straight from sunrise and becomes full power generation, and the state continues until sunset. For this reason, in general, in the case of the same irradiation area, the power generation amount of the tracking type is 1.4 times that of the fixed type (power generation is much more in the shaded area in the figure). There are an increasing number of tracking and installation types.

In addition, if the area to which sunlight hits is the same and the power generation amount is the same, the flat panel type requires a power generation element with the size of the irradiation area of the sunlight, whereas the concentrating type For example, if the light can be condensed to an area of 1/100, a power generation element having a size of 1/100 relative to a flat plate type is sufficient.
Incidentally, the tracking power is about 0.5% of the power generation amount in the tracking type solar power generation apparatus. For this reason, the tracking type requires installation cost, but the running cost is not much different from the fixed type.

  As described above, the concentrating / tracking solar power generation device (hereinafter simply referred to as “tracking solar power generation device”) is superior to both flat plate / fixed type and flat plate / tracking type solar power generation devices. If the cost is resolved, it will be mainstream in solar power generation in the future.

This tracking type solar power generation apparatus will be described with reference to FIG. 1. A lattice frame F is placed on the tracking frame D in the left-right direction (around the axis of the tracking frame D) and in the vertical direction ( Generally, it is attached to the frame F along the axis of the tracking stand D so as to be rotatable by an electric motor E or the like, and the concentrating solar power generation panel P is arranged vertically and horizontally on the frame F.
Moreover, the solar power generation panel in the tracking type solar power generation apparatus will be described with reference to FIGS. 2 to 5. The housing 10 in which the entire periphery of the bottom plate 11 is surrounded by the side plate 12, and the opening of the housing 10. And a power generation element 22 provided in the housing 10 and corresponding to each of the condensing lenses 24a, and directly reaching about 70% of the sunlight irradiated to the condensing lens 24a. Light is collected (condensed) by the condensing lens 24a and applied to the power generation element 22 to generate power.

JP 2002-289896 A JP 2008-4661 A

In this tracking solar power generation device, if each solar power generation panel P is not correctly supported and fixed to the frame F, solar power generation is performed with respect to the sun at each position corresponding to the tracking (tracking date) of the frame F. The panel P (the condensing lens plate 24) does not face at a right angle, and all of the direct light from the sun is not condensed on the power generation element 22, resulting in a decrease in power generation efficiency.
Today, where improvement in power generation efficiency is screamed, it is desirable to avoid as much as possible the reduction in power generation efficiency due to the degree of installation of the photovoltaic power generation panel P in the tracking frame F.

  Further, in the tracking type solar power generation apparatus, the cost (work cost) for installing the tracking base D and attaching the solar power generation panel P to the base D occupies about 1/3 of the total cost, Increasing the number of work steps for correctly fixing and supporting each photovoltaic power generation panel P to the frame F results in an increase in the work cost, and thus it is desirable to avoid as much as possible.

  This invention makes it a subject to enable each solar power generation panel P to be supported and fixed correctly to the flame | frame F simply and cheaply in view of the said actual condition.

In order to achieve the above object, according to the present invention, a through hole and a mark for receiving light passing through the through hole are provided on the side surface of the housing of the concentrating solar power generation panel, and the solar power generation panel P (the condensing lens plate 24) is provided. When the light passing through the through-hole orthogonal to () hits the mark, it is determined that “the photovoltaic power generation panel P is supported and fixed at the correct position of the frame F”.
If the light passing through the through hole perpendicular to the photovoltaic panel P hits the mark, the direct light of the sun is perpendicular to the condenser lens. Is fixed and fixed at the correct position of the frame F. If the positions of the through hole and the mark are set in advance so that it can be determined that the light passing through the through hole hits the mark, The solar power generation panel P is supported and fixed at the correct position of the frame F.

  As a configuration of the present invention, it is used in a tracking type solar power generation apparatus that tracks the sun to generate power, and is provided in a concave casing that surrounds the entire periphery of the bottom with a side part, and a plurality of openings provided in the opening of the casing. In the concentrating solar power generation panel provided with a condensing plate on which the condensing lens is formed and a power generation element provided in the casing and corresponding to the condensing lens, at least three formed on the side portion It is possible to employ a configuration in which the above-described through-holes and marks on which light passing through the respective through-holes parallel to the light orthogonal to the light collector strikes are provided on the side portions closer to the bottom than the respective through-holes.

In this configuration, the number of the through holes is at least three because the object can be fixed three-dimensionally when three points are determined, so that “the photovoltaic power generation panel P is supported at the correct position of the frame F”. If it can be determined that it is “fixed”, the entire photovoltaic power generation panel is supported and fixed at the correct position of the frame. The position of this through-hole may be any, but usually the photovoltaic power generation panel can be mounted upside down. Therefore, the through-hole is provided at a vertically symmetrical position on the upper and lower side surfaces (side plates) when the photovoltaic power generation panel is attached to the frame. Then, even if the photovoltaic power generation panel is mounted upside down, the confirmation position (through hole position) in all the photovoltaic power generation panels is the same, so that the operation can be performed smoothly and accurately.
Moreover, a through-hole is arbitrary with the circular hole etc. which have a notch shape or a full periphery. However, if the latter has a full circumference, such as a circular hole, water droplets such as rain enter the hole to form a water film to form a lens, and whether or not it hits the mark due to light scattering etc. It may be difficult to judge. On the other hand, the notch shape has an advantage that a water drop due to rain or the like is cut off due to the presence of the opening to reduce the possibility of becoming a lens shape.

  The through hole and the mark must be at a position where light orthogonal to the solar power generation panel (condensing lens plate) passes and a position where the passing light hits. Since a flange facing outward is formed, a through hole is provided in the flange. However, even if there is no flange, if there is a protruding piece facing outward on the peripheral edge of the side opening, or if the protruding piece is provided separately, or a protruding piece is provided midway in the width direction of the side part, etc. Since the through-hole through which the through-hole passes can be provided in the side plate through the protruding piece, the position and mode of the side portion where the through-hole is provided may be determined appropriately in consideration of this point.

  In addition, the side part (side plate) is usually perpendicular to the bottom part (bottom plate) or inclined to the inside of the housing and does not have a surface on which the orthogonal light hits through the through hole. Protruding pieces that are directed outward from the side portions or the bottom portions are provided, and marks are provided on the protruding pieces. However, if the side portion is inclined outward and has a surface on which the orthogonal light strikes, a mark can be provided on the side surface.

Thus, the mark and the through hole, between reaching the bottom from the opening peripheral edge of the side portion, but the position is arbitrary as long as capable of exhibiting the effect of the present invention, for example, placemarks, sides and bottom Since the joint surface (ridge) of the panel is the farthest from the through hole and the accuracy of checking the orthogonality of the panel with respect to the orthogonal light is high, the projecting piece is extended from the bottom side, and the projecting piece is marked. It is preferable to provide it. Even when a mark is provided on the projecting piece extending from the bottom, it can be said that the mark is substantially provided on the side because the mark is located on the edge of the side.

  It is common for each solar power generation panel to be assembled with screws (bolts) attached to the frame of the tracking platform. In this case, the solar power generation panel is screwed to the frame, and in this state, it is attached to the condenser lens plate. Pass orthogonal straight light through each of the through holes, and check whether the light passes through all of the marks. If even one of them is off, tighten each screw or insert a washer. If this solar power generation panel is assembled so that all the light transmission matches each mark by tightening, etc., each solar power generation panel can be accurately and easily attached to the tracking frame. Along with the date of the gantry, the direct light from the sun always enters the photovoltaic power generation panel straight and high-efficiency power generation is performed.

When a mark is provided on a separate projecting piece, the mark is usually unnecessary if the photovoltaic panel is attached to the mounting frame, and the mark often becomes an obstacle. Prior to shipment of the photovoltaic panel, the projecting piece may be provided in a factory or the like, and the projecting piece may be removed after installation on the gantry.
The tracking solar power generation device in this case includes a plurality of solar power generation panels and an installation support portion for installing the plurality of solar power generation panels, and the solar power generation panel has a side portion around the entire periphery of the bottom portion. Comprising a concave housing surrounded by a condensing plate, a condensing plate provided in an opening of the housing and formed with a plurality of condensing lenses, and a power generating element provided in the housing and corresponding to the condensing lens And it becomes the structure by which the said through-hole for positioning with respect to the said installation support part of at least 3 or more photovoltaic power generation panel is formed in the said side part in the housing | casing of the photovoltaic power generation panel.

There are various light generators that apply straight light (orthogonal light) to the mark through the through hole. For example, a base that is in contact with the condenser lens plate and a straight light that is fixed to the base. When the base is brought into contact with the surface of the condensing lens plate, the light emitter adopts a configuration in which the straight light emitted from the light emitter is orthogonal to the condensing lens plate. it can.
In this light emitting tool, when the base is placed on the condenser lens plate and the light from the light emitter is positioned so as to pass through the through-hole, the light is straight light, so that the light passing through the through-hole If it hits the mark, the through hole and the mark will be on the same straight line at that position. If this operation is performed at least at three points, the entire photovoltaic power generation panel is supported and fixed at the correct position of the gantry frame. For this reason, the solar power generation panel always collects all the direct light from the sunlight reaching the condensing lens by the condensing lens, as the condensing lens plate is always orthogonal to the sunlight as the tracking platform sun tracks. The light is collected (condensed) and applied to the power generation element, and smooth solar power generation is performed.

  Laser light or the like can be considered as the straight light, but even light from a general light bulb, the same light emitting diode, etc. can be used if the light passing through the through hole is thin (if the through hole is sufficiently small). ), It is possible to confirm that the through hole and the mark are on the same straight line when hitting the mark, and light from these light sources is also included.

  In the present invention, when the light passing through the through hole orthogonal to the photovoltaic panel hits the mark, “the photovoltaic panel P is supported and fixed at the correct position of the frame F. Therefore, it is possible to easily and inexpensively support and fix each photovoltaic power generation panel on the frame of the tracking base easily and inexpensively. For this reason, while aiming at the cost reduction of a solar power generation device, power generation efficiency can be improved at low cost.

  The present invention provides a concave housing in which the entire periphery of a bottom plate serving as a bottom portion is surrounded by a side plate serving as a side portion, a condensing lens plate provided in an opening of the housing, and the condensing lens provided in the housing. A photovoltaic power generation panel P including a power generation element corresponding to each condenser lens of a lens plate, for example, a tracking solar power generation apparatus having a plurality of photovoltaic power generation panels P shown in FIG. adopt.

  In this tracking type solar power generation apparatus, a grid-like frame F is placed on the tracking frame D in the left-right direction (around the axis of the tracking frame D) and in the vertical direction (along the axis of the tracking frame D). And a concentrating solar power generation panel P arranged vertically and horizontally on the frame F. The number of vertical and horizontal arrangements of the concentrating solar power generation panel P is arbitrary. Moreover, this tracking type solar power generation device can be arranged vertically and horizontally to form a concentrating solar power generation system (equipment). The number of vertical and horizontal arrangements of the tracking solar power generation apparatus is also arbitrary.

The photovoltaic power generation panel P has a size and weight (lightweight and thin) that can be carried by one person as, for example, length: 850 mm , width: 650 mm , and thickness: 95 mm . In addition, when the size is about this size, the production cost of the condensing plate (condensing lens plate 24) or the like can be reduced, or the power generating element 22 can be automatically mounted, etc., by applying production technology such as thin TVs and LED lighting fixtures in Japan. The cost can be reduced.

In the center of each panel P, a solar azimuth meter (solar daily indicator) C ₁ , an all-sun radiometer C ₂ and a direct sunlight photometer C ₃ are arranged, and the solar azimuth meter C ₁ positions the sun. (Azimuth) is confirmed, and based on the confirmation signal, the frame F moves left and right and up and down, and the angle of rotation θ and the angle of attack α are directed straight to the sun.
In other words, it is always controlled by the azimuth (rotation angle) that makes the light receiving surface of the photovoltaic panel P move from the east to the west, tracking the daily operation of the sun. In addition to the high daytime and sunset again when the altitude is lowered, it is controlled by the elevation angle (attack angle) that makes the light receiving surface of the photovoltaic power generation panel P movable in the elevation angle direction in addition to the daily altitude change of the sun, The panel light-receiving surface is in a state where the power generation efficiency is the best, and each photovoltaic power generation panel P (light-receiving surface) faces straight (right angle) toward the sun (the light-receiving surface faces directly).
Moreover, the solar radiation amount of the whole sky is detected by the global solar radiation meter C ₂ , the solar radiation amount of the direct light is detected by the solar direct light meter C ₃ , and the power generation efficiency etc. is determined by comparing the detected amount and the power generation amount. Calculated.

  As shown in FIGS. 2 to 5, the photovoltaic power generation panel P is provided with 12 rows of high heat dissipation flexible printed circuit boards (FPCs) 21 in a rectangular frame-shaped metal box frame (housing) 10. On top, a compound power generation semiconductor (cell), for example, a small-sized power generation element (for example, a side of 5 mm regular square) 22 made of a III-V compound semiconductor, and a backflow prevention diode 23 are arranged at intervals of the following condenser lens 24a. Has been. This group III-V compound semiconductor exhibits a photoelectric conversion efficiency about twice that of the crystalline silicon type cell.

  Further, the front surface of the housing 10 is covered with a condensing lens plate 24 in which a condensing lens (for example, a regular square of 5 cm per side) 24a is arranged vertically and horizontally (vertically: 16 pieces, horizontally: 12 pieces). In addition, the center of each condenser lens 24 a faces each power generation element 22. For this reason, the sunlight condensed by the condensing lens 24a is irradiated on the power generation element 22 in a large amount (direct light), and efficient power generation is performed.

As shown in FIGS. 4 and 5, the casing 10 is formed by integrally forming a bottom plate (bottom portion) 11 and a side plate (side portion) 12 from an aluminum alloy 5000 series, for example, an aluminum alloy plate of A5052P, by drawing with a press. (One-piece molded product). At that time the pressing or after, the bottom plate 11, the longitudinal direction of the convex ribs 13, the mounting hole 14 to the frame F (see FIG. 3 (b)), FPC positioning projection 15 is formed, the side plate 12, through The air holes 16 and positioning holes (through holes) 17 to the frame F of the photovoltaic power generation panel P are formed.

  The position and the number of the mounting holes 14 may be any as long as the photovoltaic power generation panel P is firmly and stably fixed to the frame F. For example, when the four corners of the housing 10 are located, the bottom plate 11 is interposed between the fixing positions. Struck (bent) and the distance between each condenser lens 24a and each power generating element 22 is not constant (not stable), but as shown in FIG. If the blind nut 20 is located), the waviness of the bottom plate 11 is reduced, and the difference in the XY-axis direction (displacement) in the distance between each condenser lens 24a and each power generating element 22 is minimized. The distance from the side plate 12 to the inside of the mounting hole 14 is appropriately set in consideration of not only the degree of deviation but also the mounting property of the photovoltaic power generation panel P to the frame F.

  The protrusions 15 are arranged so as to be located on both sides of each power generating element 22, and by fitting the protrusions 15 into the holes of the FPC 21, each power generating element 22 coincides with the center (axial center) of each condenser lens 24 a. To do. The FPC 21 is bonded and fixed to the bottom plate 11 and the side plate 12 of the housing 10 with a silicon-based adhesive.

  If the FPC 21 is disposed, the lateral rib plate 18 is caulked to the bottom plate 11 (caulking rivet 18a) and attached in a watertight manner. The rib plate 18 and the rib 13 ensure the flatness of the bottom plate 11. Furthermore, the installation mode of the rib 13 and the rib plate 18 is vertically and horizontally (vertically and horizontally) symmetrical. Even if the bottom surface (bottom plate 11) of the housing 10 is bent so as to wave, the ribs 13 and 18 are arranged between the ribs 13 and 18. Therefore, the fluctuation in the distance between the condensing lens 24a (plate 24) and the power generation element 22 is small. . In this embodiment, the deviation (difference) in the distance between each power generating element 22 and each condenser lens 24a is within ± 1 mm. The number of ribs 13 and rib plates 18 is arbitrary as long as there is no hindrance to the installation of the FPC 21. Further, the rib 13 can be in the vertical direction and the rib plate 18 can be in the horizontal direction.

  The ventilation holes 16 are provided symmetrically on the upper and lower side plates 12 of the housing 10 and fitted with a waterproof cap 16a with an adhesive interposed therebetween. The cap 16a is excellent in chemical resistance and heat resistance. The housing 10 is made of tetrafluoroethylene resin (PTFF), for example, Poreflon (registered trademark) manufactured by Sumitomo Electric Fine Polymer Co., Ltd., and smoothly circulates air while blocking moisture from outside the housing 10. Smooth ventilation inside.

In this embodiment, each FPC 21 is also connected in parallel by the FPC 21a, and the FPC 21a is connected to the terminal box 25 on the outer surface of the side plate 12. The connection mode of each FPC 21 is arbitrary, such as parallel, series, partial parallel, partial series, and the like. In the figure , 26 is a cable for guiding the power generated by the solar power generation panel P to the outside, and the solar power generation panels P on the mount D are connected in parallel or in series with this cable 26. The tracking solar power generation system is set as the required power generation (rated).

The condensing lens plate 24 is a single piece in which a silicon resin film is formed on the back surface of a glass plate or an acrylic plate, and a Fresnel lens 24a (one side: 5 cm square) is formed on the film by vertical and horizontal cutting. . The F value of the condenser lens 24a is 1.0 to 1.5. The condensing lens plate 24 is bonded and fixed to the front surface (side plate flange) of the housing 10 via a silicon-based adhesive. In this sticking, an adhesive is applied to the flange surface around the entire opening of the housing 10, the condenser lens plate 24 is pressed against the flange through the adhesive, and the locking piece 19 on the side surface of the flange is bent. Then, the condenser lens plate 24 is held.

Incidentally, in this embodiment, 192 (16 × 12) small power generation elements 22 (5 mm square) are arranged in a condensing lens plate 24 of length: 800 mm , width: 600 mm , and thickness: 3 mm. Therefore, a large space (2500-25 (5 × 5) = 2475 mm ² ) is formed around the power generation element 22 with respect to the size of the condenser lens 24a (50 × 50 = 2500 mm ² ). Since there is a large space around the power generating element 22, heat radiation from the bottom plate 11 (FPC 21) is effectively performed. That is, it has a structure with high heat dissipation.

  In order to attach the photovoltaic power generation panel P having this configuration to the tracking base D, the bottom plate 11 is screwed (bolted) to the lattice frame F. At this time, as shown in FIG. 3, a blind nut (pierce nut) 20 is caulked together with the rib plate 18 to the bottom plate 11, and a bolt 20 a that penetrates the frame F is screwed into the blind nut 20. Install the photovoltaic panel P.

At that time, as shown in FIG. 6, it is confirmed whether or not the photovoltaic power generation panel P is attached at the correct position of the tracking base D with the light generator 30 attached to the photovoltaic power generation panel P. The light generator 30 is composed of a base 31 having a U-shaped cross section and a light-emitting device 32 of straight light fixed to the base 31.
As shown in the figure, when the base 31 is brought into contact with the surface of the condensing lens plate 24 so as to correspond to the positioning holes 17 individually, the light generator 30 emits laser light (straight forward) from the light emitter 32. The light a) is orthogonal to the condenser lens plate 24, and the light a is passed through the positioning hole 17 to determine whether or not the light passing a hits the mark b. This determination is performed for each positioning hole 17, and it is confirmed whether or not the light a that has passed through each positioning hole 17 hits all the respective marks b. Then, it is tightened with a washer so that all the rays a coincide with the mark b. At this time, the determination in each positioning hole 17 is preferably performed at the same time, but as long as it is allowed, it is arbitrary such as one place and two places.

By this operation, each photovoltaic power generation panel P is attached in parallel to the frame F of the tracking platform D, and the axis around the tracking platform D and in the vertical direction (along the axis of the tracking platform D). Along with the rotation, the direct light from the sun always enters straight (vertical) into each photovoltaic power generation panel P (each condensing lens 24a), and highly efficient power generation is performed.
The state in which the solar panels P in the frame F is mounted correctly, the frame F is the rotation angle θ and angle of attack α facing straight to the sun by the solar azimuth meter C _1, the solar panels Of course, P (each condensing lens plate 24) faces straight to the sun, and almost all of the direct light is condensed on the power generation element 22.

If there are at least three positioning holes 17 and marks b, the photovoltaic power generation panel P can be positioned. However, since this type of photovoltaic power generation panel P is usually symmetrical vertically, it is mounted upside down. However, since it becomes the same mode, it is preferable to provide the positioning holes 17 and the marks b at the symmetrical positions. In this embodiment, the positioning holes 17 and the marks b are provided symmetrically at the upper side and the lower side. For this reason, even if this photovoltaic power generation panel P is mounted upside down, there is no change in the position of the positioning hole 17, so that there is no hindrance to the positioning.
The projecting piece B provided with the mark b is provided in a factory or the like before shipment of the photovoltaic power generation panel P, and is removed after installation on the gantry D. The formation of the mark b is optional, such as by paint or by cutting.
The positioning hole 17 is not limited to the notch shape shown in the figure, and is optional as a circular hole having the entire periphery. However, the notch shape has an advantage that the water breakage is good even if water drops due to rain or the like enter the notch 17. If it is a circular hole, the hole is covered with a water droplet to form a lens, and there is a possibility that the light a is scattered and the like cannot be confirmed.

In the above-described embodiment, a secondary lens (rod lens: CPC) may be provided on the front surface of the power generation element 22 to make light collection uniform and increase power generation efficiency. In addition, the present invention is not limited to the concentrating solar panel P of the above-described embodiment, and can of course be adopted for various types of tracking solar panels.
Further, the casing 10 does not need to be a drawn product by pressing, for example, the bottom plate 11 and the side plate 12 are separated, and the both 11 and 12 are joined by various means such as welding, fitting, and adhesion. It can be. At this time, the side plate 12 may be a resin molded product.
Further, the configuration of the light generator 30 is not limited to the above, for example, the base 31 is not limited to a U-shaped cross section, but has a cross-sectional Ω shape, a configuration in which a light emitter 32 is provided at the center of the cross section, etc. As long as the base 31 is brought into contact with the condenser lens plate 24, any mode may be used as long as the straight light a is emitted from the light emitter 32.
Thus, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
