Description

  The present invention relates to a solar power generation device.

  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 solar power generation panel having this configuration is a flat panel 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 (Patent Document 1, FIG. 1). And the like, and a light condensing type that condenses sunlight with the lens as a light condensing plate such as a Fresnel lens, irradiates the power generation element to concentrate solar energy, and generates power (Patent Document 2, paragraphs 0025- 0026, see FIG.
Moreover, as an installation mode (solar power generation device) of a solar power generation panel, there are a fixed type that is fixed to a roof or the like, and a tracking type that is installed on a gantry that tracks the sun (tracking date), and the concentrating type Has a tracking type so that the solar power generation panel always faces the sun (direct light is orthogonal) (see Patent Document 2, paragraphs 0020 to 0021 and FIG. 1). ).

  By the way, sunlight falls on the earth with sunrise, but as shown by the two-dot chain line in FIG. The amount of power generation rises gradually from sunrise, reaches a peak near daytime, and gradually decreases toward sunset. On the other hand, as shown by the dashed line in FIG. 1, the tracking type photovoltaic power generation panel faces the sun when the sun comes out, so the direct light hits straight from the sunrise and becomes full power generation. The condition 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, and even in the flat type, the tracking type is installed on the tracking stand. Is increasing.

  In addition, if the area to which sunlight hits is the same and the power generation amount is the same, the flat panel type needs 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 planar type is sufficient.

  As described above, the concentrating / tracking solar power generation device has an excellent aspect compared to the flat plate / fixed type and flat plate / tracking type solar power generation devices. It will be mainstream.

  In this way, the concentrating / tracking type solar power generation apparatus is excellent in terms of power generation efficiency, but when the sun is hidden, such as on a cloudy day, the sun cannot be tracked, In this case, there is a drawback that the amount of power generation is extremely reduced because sunlight cannot be collected. On the other hand, since a flat plate solar cell (flat plate solar power generation device) has a power generation element in the entire light receiving surface, if light is irradiated on the light receiving surface, power is generated by the received light. In other words, even when the sun is hidden such as on a cloudy day, power generation is performed.

In addition, a tracking type solar power generation apparatus normally supports a solar power generation panel fixedly on a frame which is a support part thereof, captures the position of the sun with a solar position capture part provided on the frame, and capture information thereof Based on the above, the direction of the frame is changed to up, down, left, and right so that the photovoltaic power generation panel faces the sun. At this time, in order for all the photovoltaic power generation panels to face the sun, all the photovoltaic power generation panels need to be attached to the frame at the same level.
Conventionally, each photovoltaic power generation panel is attached to the frame by using a spirit level so that the light receiving surface is parallel to the frame. This work is complicated and requires some ingenuity. Further, the frame does not have rigidity over the entire length, and the more the frame is bent, the more the frame is bent. For this reason, it is difficult for the photovoltaic power generation panel at the center of the frame and the photovoltaic power generation panel at the end to have the light receiving surface facing the sun in the same manner.

Furthermore, in both tracking type and fixed type photovoltaic power generation devices, the photovoltaic power generation panel is fixedly supported on a frame that serves as a support part. Usually, the fixed support is performed on the bottom plate of the photovoltaic power generation panel on the frame. It is done with bolts. The bolting is performed from the back side of the photovoltaic power generation panel.
For this reason, when repairing or replacing the photovoltaic power generation panel, the bolt is removed from the back surface of the photovoltaic power generation panel, and the solar cell is removed and attached. At this time, since the photovoltaic power generation panel is attached to the upper surface (front surface) of the frame in the vertical and horizontal directions, the removal and attachment of the photovoltaic power generation panel is usually performed from the surface side. For this reason, the bolting operator on the back surface side and the operator for removing and attaching the solar power generation panel are required on the front and back sides of the solar power generation panel group. The need for many workers increases the work cost.

  The present invention has a first object of having the advantages of the concentrating type and the flat plate type under such circumstances, and to make all the photovoltaic power generation panels arranged vertically and horizontally face the sun as much as possible. The third problem is to improve the workability of removing and installing the photovoltaic power generation panels arranged vertically and horizontally.

  The present invention for achieving the first object includes a concentrating solar power generation panel, a flat panel solar power generation panel, a support portion that supports a plurality of the solar power generation panels, and a direction of the support portion. The solar tracking solar power generation apparatus includes a drive unit that is changed vertically and horizontally and a capturing unit that captures the position of the sun provided on the support unit.

  The arrangement of the concentrating solar power generation panel and the flat panel solar power generation panel may be determined as appropriate in consideration of the mounting workability, etc. It is preferable to provide a concentrating solar power generation panel and a flat solar power generation panel outside the concentrating solar power generation panel. The up / down / left / right change fulcrum side does not change greatly with respect to the outside / up / down / left / right change of the support portion. For this reason, if the concentrating solar power generation panel is located in the region where it does not change, the accuracy of the panel tracking accompanying the solar tracking of the support portion will not be greatly reduced, and the rate at which the direct sunlight falls on the panel light receiving surface This is because the power generation efficiency increases. On the other hand, since the power generation efficiency of the flat solar power generation panel is not greatly affected by the accuracy of the direct alignment with the sun, the decrease in the power generation efficiency is small even if it is away from the up / down / left / right fulcrum.

Here, if the total light receiving area of a plurality of photovoltaic power generation panels is constant and all the photovoltaic power generation panels are flat, the power generation amount when the sun comes out from the morning to the evening and receives sunlight is shown in the figure. If it is the same condensing type, it will be shown by the same one-dot chain line. Therefore, if the photovoltaic power generation panel is divided into half (same number) as the flat panel type and the concentrating type, the power generation amount is shown by the solid line in FIG.
However, it is rare that the sun goes out from the morning to the evening and the sunlight falls, and it is difficult for the concentrating type to secure such a power generation amount. For this reason, even if there is no irradiation of sunlight, in that case, if the photovoltaic power generation panel is divided into a flat plate type and a concentrating type by half, as shown in FIG. Like the two-dot chain line, the power generation amount of the condensing type is as shown by the one-dot chain line, and the total power generation amount of both is as the solid line.
For this reason, when considered throughout the year, it is possible to obtain the largest amount of power generation by using both the flat panel type and the concentrating type solar power generation panel in combination. The ratio between the flat plate type and the condensing type is appropriately determined based on the grasped value obtained by grasping the irradiation time of sunlight at the installation place by an experiment or the like.

  The present invention for achieving the second object is provided with a photovoltaic power generation panel, a frame that supports a plurality of the photovoltaic power generation panels, a drive unit that changes the orientation of the frame vertically and horizontally, and the frame. A solar tracking type solar power generation apparatus including a capturing unit that captures the position of the sun and an appliance for confirming whether or not the solar power generation panel faces the sun, wherein the solar power generation panel is connected to the sun. An instrument for confirming whether or not they face each other is a light shielding plate fixed to the frame, a light receiving plate made of a colored transparent plate parallel to the light shielding plate, and a distance between the two plates provided between the light shielding plate and the light receiving plate The direction is composed of a light-shielding tube with a cylindrical axis, and a sunlight intake hole is formed in the light-shielding plate, and the light-receiving plate is irradiated with sunlight from the sunlight intake hole from the opposite side of the irradiation surface. Confirm the irradiation position The photovoltaic panels by the confirmation position is to that the solar tracking photovoltaic power generation unit to confirm whether directly facing the sun.

  For example, even if the capturing unit provided at the center of the photovoltaic panel group arranged vertically and horizontally captures the sun and changes the orientation of the frame so that the light receiving surface of each photovoltaic panel faces the sun ( However, the light receiving surfaces of all photovoltaic panels do not always face the sun due to frame deflection or the like. On the other hand, in this confirmation instrument, when the light receiving surface of the frame, that is, the photovoltaic power generation panel is directly facing the sun, the position of the light receiving plate irradiated with sunlight from the sunlight intake hole is shown in advance. For this reason, for example, the confirmation device is provided at the end of the frame so that the sunlight from the sunlight intake hole is irradiated to the required position (facing position) of the light receiving plate. Adjust the mounting mode of the panel. At this time, since the effective irradiation angle of the direct light with respect to the panel light receiving surface is 0.26 degrees, the light receiving surfaces of all the photovoltaic power generation panels are set to face each other within the angle.

If this confirmation instrument is attached to each photovoltaic power generation panel, it can be confirmed whether or not each panel light-receiving surface faces the sun. For this reason, on the basis of the confirmation, the mounting mode of each panel, for example, when a photovoltaic power generation panel is mounted with a bolt on the frame, adjust the number of washers between the frame passed through the bolt and the panel, and Adjust the panel mounting angle.
Moreover, you may provide this confirmation instrument for every several photovoltaic power generation panel. At this time, the confirmation instrument can be provided at the center of the photovoltaic power generation panel group.
Furthermore, this confirmation instrument is not limited to the concentrating solar power generation panel and its power generation device, but can be employed in a flat panel solar power generation panel and its power generation device, and is not limited to the solar tracking type, but a fixed type. May be adopted.
As the light shielding tube, those having an appropriate cross-sectional shape such as a cylindrical shape or a rectangular tube shape can be adopted. However, a support rod that simply supports the light receiving plate on the frame may be used as long as the position of the light receiving plate irradiated with sunlight from the sunlight intake hole can be confirmed without shielding light. Moreover, although the color of a light-receiving plate can consider black, gray, etc., if irradiation sunlight can be confirmed, it does not need to be colored. That is, it may be colorless and transparent. This is because the irradiation point can be confirmed with light even if it is colorless and transparent.

  The present invention for achieving the third object is a solar power generation apparatus including a solar power generation panel and a frame that supports a plurality of the solar power generation panels, and protrudes from a side surface of each of the solar power generation panels. The frame has a flange to which the rib piece is applied, and the opposite rib pieces of adjacent photovoltaic power generation panels are applied to the flange from the surface side of the photovoltaic power generation panel. The solar power generation apparatus has the rib pieces screwed (bolted) to the flange.

With this configuration, the solar power generation panel can be detached from the frame or attached to the frame by bolting or removing the bolt from the surface side of the solar power generation panel.
This solar panel mounting structure is not limited to the installation of a concentrating solar panel, but can also be used for mounting a flat panel solar panel. It can also be adopted.

  In addition, each invention which achieves the first to third problems can be appropriately combined with each other, or can be combined with all of the three inventions.

  Since the invention for achieving the first object is a tracking type, it has the advantages of the tracking type and uses both a flat plate type and a condensing type. Compared to a power generation device equipped with a photovoltaic panel, the amount of power generation is large.

  The invention for achieving the second object can confirm the directly facing state with respect to the sun with a simple structure. For this reason, each photovoltaic power generation panel can be correctly faced to the sun, and highly efficient power generation can be performed.

  Since the invention for achieving the third object can be detached and attached from the surface side of the photovoltaic power generation panel, the attachment and removal can be performed by one operator. For this reason, the work cost can be reduced. Incidentally, labor costs occupy a considerable weight in the installation and maintenance of photovoltaic panels, and reducing the cost will promote the spread of photovoltaic power generation.

  One embodiment of the present invention is shown in FIGS. This embodiment is the tracking solar power generation device shown in FIG. In this embodiment, eight concentrating solar power generation panels P1 in a row are provided in two stages above and below the central portion, and five flat panel solar power generation panels P2 in a row are provided in one stage on the outside thereof. . The concentrating solar power generation panel P <b> 1 and the flat solar power generation panel P <b> 2 (generic symbol: P) are attached to a frame F provided on the tracking base D. The frame F can be rotated by the electric motor E or the like in the left-right direction (around the axis of the tracking frame D) and the vertical direction (along the axis of the tracking frame D) with respect to the tracking frame D. In this embodiment, the frame F constitutes a support part that supports the concentrating solar power generation panel P1 and the flat panel solar power generation panel P2, and the electric motor E or the like makes the direction of the support part (frame F) up, down, left, and right. The drive unit to be changed is configured.

  As shown in FIG. 3, the concentrating solar power generation panel P <b> 1 is provided in a flat rectangular housing 1 in which the entire periphery of the bottom plate is surrounded by side plates and an opening of the housing 1. And a power generation element (not shown) provided in the housing 1 and corresponding to each condenser lens 3 of the condenser lens plate 2. The size is, for example, vertical: 850 mm, horizontal: 650 mm, thickness: 95 mm, etc., and the size and weight (lightweight and thin) that can be carried by one person. With this size, it is possible to reduce the manufacturing cost of the condenser lens plate 2 and the like and to reduce the cost by automatic mounting of the power generation elements, etc., by applying the production technology of Japan's thin TVs, LED lighting fixtures, etc. is there.

  As in the prior art, the flat solar power generation panel P2 is also photoelectrically converted into a flat rectangular housing 1A in which the entire periphery of the bottom plate is surrounded by side plates and the entire area inside the housing 1A as shown in FIG. A plurality of layers are laminated, and a protective glass 2A is provided on the surface (see Patent Document 1, paragraphs 0014 to 0073 and FIGS. 1 to 3).

A solar azimuth meter (solar sun diary) C1, a solar radiation meter C2, and a direct sunlight photometer C3 are arranged at the center of the frame F in which the solar power generation panels P1, P2 are arranged vertically and horizontally. The position (azimuth) of the sun is confirmed by the sun azimuth meter C1, and based on the confirmation signal, the frame F moves left and right and up and down, and is set to a rotation angle θ and an angle of attack α that face the sun (facing directly).
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. It tracks the changes in altitude of the day of the sun until high noon and sunset again. Also, each photovoltaic power generation panel P (light reception) is controlled toward the sun, which is controlled to an elevation angle (attack angle) that makes the light reception surface of the photovoltaic power generation panel P movable in the elevation angle direction, so that the power generation efficiency of the panel light reception surface is the best. Surface) is straight (right angle) (the light receiving surface is directly facing).
Moreover, the solar radiation amount of the whole sky is detected by the total solar radiation meter C2, the solar radiation amount of the direct light is detected by the solar direct light meter C3, and the power generation efficiency and the like are calculated by comparing the detected amount and the power generation amount. (See Patent Document 2, paragraphs 0023 to 0024, FIG. 1).
In this embodiment, the solar azimuth meter C1 is a tracking sensor and constitutes a capturing unit that captures the position of the sun.

As shown in FIG. 5, the attachment structure to the frame F, which is a support portion of the concentrating solar power generation panel P1, can be attached and detached from the surface side. That is, the frame F is configured by arranging the members 10 made of channel steel in a vertical and horizontal lattice shape and integrating the members 10 by bolting (screwing), welding, or the like (see FIG. 5C).
Moreover, the concentrating solar power generation panel P1 has rib pieces 15 protruding laterally on its side surface. For this reason, as shown in FIG. 5C, the rib pieces 15 and 15 of the adjacent concentrating solar power generation panels P1 and P1 are applied to the upper flange 11 of the frame member 10, and the upper side (concentrating solar panel) From the photovoltaic panel P 1), a fixture (fastener) 12 is further applied to the flange 11 via the rib piece 15, and the fixture 12 is fastened with a bolt 13. The fastening position by the fixing tool 12 is appropriately set on the front and rear side surfaces and the left and right side surfaces of the concentrating solar power generation panel P1 so that the concentrating solar power generation panel P1 can be firmly fixed and attached.

As shown in FIG. 5 (A), the fixture 12 includes angle-shaped pressing pieces 12A that rise on both front and rear sides and diagonally downward pressing pieces 12B on both sides between the front and rear pressing pieces 12A. For this reason, when this fixing tool 12 is fastened to the flange 11 by the bolt 13, the pressing pieces 12 </ b> B and 12 </ b> B press the rib pieces 15 against the flange 11 to fix the concentrating solar power generation panel P <b> 1 to the frame member 10. Further, the pressing piece 12A is pressed against the surface side edge of the concentrating solar power generation panel P1 to press the concentrating solar power generation panel P1, fixing the concentrating solar power generation panel P1, and a condensing lens. The plate 2 is pressed to prevent its falling. With these presses, the concentrating solar power generation panel P <b> 1 is firmly fixed and attached to the frame member 10.
At this time, the fixture 12 and the bolt 13 are attached to the frame member 10 in advance, and the fixture 12 is movable with respect to the bolt 13 in the axial direction. In this state, the concentrating photovoltaic power generation panel P1 is mounted on the frame member 10 from the front side of the frame F so that the rib pieces 15 enter between the upper flange 11 and the pressing pieces 12A and the pressing pieces 12B of the fixture 12. And then fasten with bolts 13.

  Thus, workability | operativity will become favorable by performing attachment / detachment of the concentrating photovoltaic power generation panel P1 from the surface side. In particular, since this concentrating solar power generation panel P1 is attached in the middle of the frame F, it is effective that it can be removed and attached from the surface side. The removal of the concentrating solar power generation panel P1 is performed by an operation reverse to the attaching operation.

  The flat solar power generation panel P2 can have the same mounting manner as the concentrating solar power generation panel P1 as having the rib pieces 15 on the side surfaces. However, in this embodiment, it is attached by bolting from the back surface side of the frame member 10 as in the prior art. This is because the flat solar power generation panel P2 is attached to the upper and lower portions of the frame F, and therefore it is easy to attach and remove from the back side as compared with the concentrating solar power generation panel P1.

In this embodiment, confirmation tools 20 for confirming whether or not each concentrating solar power generation panel P1 and flat solar power generation panel P2 are facing the sun are provided at both lower ends of the frame F. .
As shown in FIG. 6, the confirmation instrument 20 includes a light shielding plate 21 fixed to the frame F, a light receiving plate 22 made of a colored transparent plate parallel to the light shielding plate 21, and a space between the light shielding plate 21 and the light receiving plate 22. The distance between the two plates 21 and 22 provided in the lens is composed of a light shielding cylinder 23 having a cylindrical axis.
When the light receiving surface (light-shielding plate 21) of the frame F, that is, the photovoltaic power generation panels P1 and P2, is directly facing the sun, the confirmation instrument 20 has sunlight C from the sunlight intake hole 24 at the center of the light-shielding plate 21. The position of the light receiving plate 22 irradiated with is shown in advance. The position is the center 22a by drawing a plurality of concentric circles by scribbling or scoring in a lattice shape. The interval between the light shielding plate 21 and the light receiving plate 22 (the length of the light shielding tube 23) is arbitrary as long as the solar facing can be confirmed, and is determined appropriately by experiments or the like.
For the integration of the light shielding plate 21 and the light shielding tube 23 and the light shielding tube 23 and the light receiving plate 22, appropriate means such as welding or bolting (screwing) are adopted. In this embodiment, the bolt 26 is used.

The confirmation instrument 20 is attached by bolting the light shielding plate 21 to the frame member 10 through the bolt hole 25. In this mounted state, the position (azimuth) of the sun is confirmed by the solar azimuth meter C1, and based on the confirmation signal, the rotation angle θ and the angle of attack α are set so that the frame F moves left and right and up and down to face the sun. However (even after tracking), the light receiving surfaces of all the photovoltaic power generation panels P1 and P2 do not always face the sun due to the bending of the frame F or the like.
For this reason, with this confirmation instrument 20, the attachment mode of the photovoltaic panels P1 and P2 is adjusted so that the sunlight C from the sunlight intake hole 24 is irradiated to the center 22a of the light receiving plate 22, and the frame 10 It adjusts so that light-receiving surfaces, such as the flat type photovoltaic power generation panel P2 etc. which were provided in the edge of this, may face the sun. At this time, the path of the sunlight C between the light shielding plate 21 and the light receiving plate 22 is shielded by the light shielding cylinder 23, and the light receiving plate 22 is colored, so the irradiation position of the sunlight C on the light receiving plate can also be confirmed. Easy and accurate.
Adjustment of the attachment mode of the concentrating solar power generation panel P1 is performed by adjusting the vertical and horizontal position on the surface of the frame F of each panel P, and between the pressing pieces 12B and 12B and the rib piece 15, or with the rib piece 15 An intervening piece such as a washer is inserted between the flanges 11 and moved up and down with respect to the surface of the frame F of the panel P. At this time, since the irradiation angle of the direct light is 0.26 degrees, the facing angles of the light receiving surfaces of all the photovoltaic power generation panels P are included within the angle.

  Thus, if the confirmation instrument 20 is provided at the end of the frame F, the end of the frame F is usually bent most, and the solar power generation panel P located at the end is out of alignment with the sun. By adjusting the angle of the light receiving surface of the solar photovoltaic power generation panel P with respect to the sun within 0.26 degrees that is the irradiation angle of direct light, all the concentrating photovoltaic power generation panels P1 and the flat panel photovoltaic power generation panels The light receiving surface of P2 can be positioned within 0.26 degrees that is the irradiation angle of direct light. If the angle of the light receiving surfaces of the solar power generation panels P at both ends is within 0.26 degrees, which is the irradiation angle of direct light, the angle of the light receiving surfaces of the solar power generation panels P positioned therebetween is also direct. This is because the light irradiation angle is within 0.26 degrees.

This confirmation instrument 20 is not limited to the end of the frame F, but is optional as long as it exerts its action. For example, it is provided next to the capture unit (solar azimuth meter C1), provided at the four corners of the frame F, provided at each photovoltaic power generation panel P, or provided at the center of the plurality of photovoltaic power generation panels P.
Further, the position of the capturing part (solar direction meter C1, etc.) is the center of the group of concentrating solar power generation panels P1 arranged vertically and horizontally as in the above-described embodiment, and the vertical and horizontal rotations of the frame F at the center. It is preferable that the moving fulcrum is located. However, the position of the capturing portion is not limited to the center of the frame F, and is provided at the vertical and horizontal rotation fulcrums of the frame F, or provided on the center line in the horizontal direction of the frame F. As long as it is optional. For example, as shown in FIG. 7, the frame F can be provided at the lower end on the center line in the left-right direction.

  Although arrangement | positioning aspects, such as the arrangement | positioning ratio of the concentrating photovoltaic power generation panel P1 and the flat type photovoltaic power generation panel P2, should just be determined suitably considering electric power generation efficiency etc., the aspect shown to FIGS. 8-12, for example Can be considered.

In the embodiment shown in FIG. 10, for example, the concentrating solar power generation panel P1: 8, 16, 32, 64, 96, 128 is installed for each number of flat solar power generation panels P2: 4, 6, 8, The number of installations such as 16, 24, and 32 can be considered. In the mode shown in FIG. 11, for example, with respect to the number of installed concentrating solar power generation panels P1: 32, 64, 96, 128, installation of flat solar power generation panels P2: 10, 20, 30, 40, etc. Number is conceivable. In the aspect shown in FIG. 12, for example, with respect to the number of installed concentrating solar power generation panels P1: 8, 16, 32, 64, 96, 128, flat solar power generation panels P2: 12, 12, 18, The number of installations such as 32, 42, and 52 is conceivable.
