Description

  The present invention is a solar power generation panel installation unit used to increase the power generation efficiency by installing a plurality of solar power generation panels having solar cells capable of generating electricity on both sides, on water, on land, on a building, And a photovoltaic power generation array connecting a large number of them.

  Power generation using fossil fuels, such as oil-fired power generation and natural gas-fired power generation, generate carbon dioxide and accelerate global warming. Nuclear power also has problems such as the danger of large-scale accidents and the disposal of large amounts of radioactive waste. Therefore, in recent years, there has been a shift to power generation using clean energy such as solar power generation, wind power generation, and hydroelectric power generation.

  In particular, photovoltaic power generation has been widely used, from commercial power generation on wide lands to small-scale power generation on house roofs.

  Photovoltaic power generation is commercially performed by installing solar panels on land such as fallow lands and wilderness, on buildings such as rooftops, or on water such as lakes, marsh ponds, and the sea. When installed on land, land reclamation work is required, and it is difficult to secure a vast site. Once installed, there is a disadvantage that it can only be used for power generation only, but effective use of fallow land and wilderness There is a merit that can be done. In addition, when installed on a building, there is an advantage that it is easy to construct because it is flat, and a site that is not usually used can be effectively used. On the other hand, when installed on water, it does not require land reclamation work, it is possible to secure a vast water area at low cost, and even if it is installed, it will continue to be used for such purposes as fishing, agriculture, water storage and water adjustment in that water area There is an advantage that it is possible.

  Patent Document 1 discloses a photovoltaic power generation unit that holds a photovoltaic power generation panel on water to generate electric power, and includes a photovoltaic power generation panel, and a holding portion that holds the photovoltaic power generation panel on a surface, and is opposite to the surface. A float having a rectangular shape in a plan view provided with a non-slip convex portion during walking on the back surface of the side, the float holding the photovoltaic panel floating the front side on the water, and floating the back surface on the water, The float, which also serves as a buoyant body, a scaffold and a passage, which individually generates buoyancy, and one end on the short side of the float, in which the front side is floated on water and the solar power generation panel is held. There is disclosed a photovoltaic power generation unit comprising: a corridor plate having a rectangular shape in a plan view, which is held by a concave portion provided at the center of the longitudinal side on the back side.

  In the photovoltaic power generation, if the temperature of the photovoltaic power generation panel rises too much, the power generation amount decreases. In particular, in solar power generation under the scorching sun and no wind on a land or a building where the solar power generation panels are closely connected, the temperature inside the solar power generation panels rises to 70 to 80 ° C. at the maximum. It is said that the power generation efficiency is highest when the internal temperature is around 25 ° C., and that the power generation efficiency decreases by 0.5% each time the temperature rises by 1 ° C.

  Solar power generation on water has higher power generation efficiency than on land because the temperature rise of the solar power generation panel hardly occurs due to the cooling effect from the water surface. However, if the photovoltaic power generation panels are densely installed on the water to improve the power generation efficiency per unit area, the ventilation becomes poor, the cooling efficiency is reduced, and the power generation efficiency is reduced.

  In photovoltaic power generation on water, the power generation efficiency per unit area together with the power generation efficiency per photovoltaic panel can be further improved, it can be easily installed, and it is easy to maintain and manage even on unstable water. There has been a need for a solar power panel installation unit on water and a photovoltaic array to which a plurality of such units are connected.

  In addition, solar power generation on land and on buildings can also improve power generation efficiency, maintain cooling effects, can be easily installed, and can be moved and re-installed when rooftop waterproofing is reconstructed. There is a need for a solar panel installation unit on land or on a building, which is easy to operate, and a photovoltaic array to which a plurality of units are connected.

  In addition, from the viewpoint of production cost reduction, there is a demand for a solar panel installation unit and a solar array that can be installed on both land and buildings using the same solar panel installation unit. I have.

  Hereinafter, embodiments for carrying out the present invention will be described in detail, but the scope of the present invention is not limited to these embodiments.

  As shown in FIG. 1 and FIG. 2, the installation unit 1 of the photovoltaic panel 10 of the present invention supports the photovoltaic panel 10 (also called a solar cell module or a solar panel) and the photovoltaic panel 10. Pedestal 13, a bridge bar 40 on which the pedestal 13 is mounted and fixed, an installation table 20 on which the bridge bar 40 is bridged, mounted and fixed, and a plurality of installations And a light emitting material that is bridged between the tables 20 and intermittently arranged.

  The photovoltaic power generation panel 10 is of a type that can generate power on both the front surface 10a and the back surface 10b. The solar panel 10 includes a plurality of cells 11 each having a solar cell element. The solar panel 10 is directed upward so that the front surface 10a can directly receive sunlight, and downward (water surface) so that the back surface 10b can receive reflected light.

  As the solar cell element, a semiconductor of P-type silicon and N-type silicon, which are the solar cell elements in the solar panel 10, is used. In the case of solar power generation, when sunlight hits the junction between P-type silicon and N-type silicon, electrons and holes are generated, and the electrons are attracted to N-type silicon and the holes are attracted to P-type silicon. This makes it possible to extract electricity. The cell 11 may be composed of only a solar cell element or may be covered with glass or resin, and is a basic unit of a solar cell.

A photovoltaic panel 10 capable of generating power on both sides is a package in which a plurality of cells 11 each having a solar cell element are arranged and packaged. Each of the solar panels 10 is supported by, for example, a frame 12. A plurality of photovoltaic panels 10 are arranged to form a panel row 10 _line .

  The photovoltaic panels 10 that can generate power on both sides are, for example, a 60-cell single-crystal solar panel 10 that is arranged vertically 6 rows and a 72-cell single-crystal solar panel that is arranged 12 rows horizontally 6 pieces. The photovoltaic panel 10 is exemplified. Such a photovoltaic panel 10 capable of generating power on both sides is, for example, laminated with a windshield, an EVA (ethylene-vinyl acetate copolymer resin) layer, a solar cell element, an EVA layer, and a back glass, and is made of metal such as aluminum or stainless steel. It is fitted into a frame made of steel. In this commercial photovoltaic panel 10, the light receiving efficiency of sunlight on the front surface 10a and the power generation amount on the back surface 10b slightly vary depending on the light receiving efficiency of scattered light, reflected light, and the like. The output is about 290-310W.

The photovoltaic power generation panel 10 that can generate power on both sides is installed to be inclined southward toward the sunlight in order to increase power generation efficiency. When fixing the inclination angle, the direction and the angle are adjusted so that the front surface 10a of the photovoltaic panel 10 is directed to the sunlight for the longest time. In the photovoltaic power generation panel 10, the frame 13 has a frame lower end 12a supported by the frame 13 with a rotating shaft 41 so that the back surface 10b can be easily maintained and managed, as shown by an arrow in FIG. , May be movable. The solar panel 10 may be of a solar tracking type. The respective photovoltaic panels 10 in each panel row 10 _line of the photovoltaic panels 10 may be arranged with little or no gap.

The photovoltaic power generation panels 10 are connected and supported by an upper frame cross beam 14 and a lower frame cross beam 16, respectively, to form a panel row 10 _line, and a plurality of installation stands 20 are installed along the panel row 10 _line. The _bridges 23 are connected to each other by a table connecting bar 27 to form a connecting table connecting line 20a- _line, and the grooves 23 of the mounting tables 20 (see the sectional view taken along the line AA in FIG. 4 (a), see FIG. 5 (a)). bar 40 is fitted, at the end of each of the installation base bound column 20a _-line, another installation base 20 so as to be orthogonal to them, while no installation base crosslinking column 20b _-line crosslinked with installation base cross bar 28 The mounting table connecting bar 27 is fixed. The installation table connecting bar 27 and the installation table bridge bar 28 are, for example, metal angles having an L-shaped cross section.

Each of the photovoltaic panels 10 capable of generating power on both sides is supported and fixed on a pedestal 13, and the pedestal 13 for each of the photovoltaic panels 10 is placed on a bridge bar 40, and 10 panel column every 10 _line of sandwiched by setting stand bound column 20a _-line of the installation base 20, on the installation base coupled columns 20a _-line between two pairs of mount base 20 for each of the central grooves 23, each bridge bar 40 are bridged and mounted.

The installation unit connecting rows 20a- _line and 20b-line _allow the installation units 1 to be installed floating on the water or installed on land or on a building.

A light that is a reflector that reflects sunlight to the back surface 10b of the photovoltaic panel 10 at a position lower than the photovoltaic panel 10 and at a predetermined position on the water surface, on land (on the ground), or on the surface of a building. The shooting material 30 is intermittently arranged. The light _emitting material 30 is _bridged between two pairs of the mounting tables 20 of the mounting table connecting rows 20a-line of the mounting tables 20 and / or bridges the bridge bars 40 of the respective solar panels 10. Is provided. For example, as shown in FIGS. 1 and 2, the light emitting material 30 extends the entire bridge bar 40 in the panel row 10 _line in parallel with the panel row 10 _line and slightly longer than the panel row 10 _line. It is provided to bridge.

Light morphism member 30, and between the panel row 10 _line between the photovoltaic panel 10, and between the adjacent solar panels 10 of each panel column in 10 _line, and beneath each photovoltaic panel 10, each Preferably, they are arranged at least either directly below the solar panel 10 or between the installation tables 20, respectively.

  The light emitting material 30 effectively utilizes the dead space of the installation unit 1 of the photovoltaic power generation panel 10, and does not directly irradiate the front surface 10 a of the photovoltaic power generation panel 10, and It is a reflecting material that reflects and / or scatters sunlight passing through the space and reaching the water surface direction toward the back surface 10b of the solar power generation panel 10, and improves power generation efficiency. At the same time, by being intermittently arranged, the effect of cooling the solar power generation panel 10 from the water surface is not significantly reduced. The light emitting material 30 may be a reflective material, a fluorescent material that emits fluorescent light with sunlight, or a light emitting material that emits light with sunlight. The light emitting material 30 may be a combination of at least one of a reflecting material, a fluorescent material, and a light emitting material. By intermittently arranging the light emitting material 30, the wider the range of the reflecting member is, the better the light emitting efficiency such as reflection is, and the narrower the range of the reflecting member is, the better the ventilation is, and the cooling effect from the water surface is improved. The contradictory effects of good are compatible.

The light _emitting material 30 is installed between the area between two pairs of the mounting tables 20 of the mounting table connecting rows 20a-line of the mounting tables 20 on the lower side of the solar power panel 10 and between the solar power panels 10. The area ratio between the area covered by the light _emitting material 30 and the area not covered by the light emitting material 30 is set to be the same in the area between the two _mounting tables 20 of the mounting table connecting rows 20a-line of the tables 20. May be different. For example, in a region between two pairs of the mounting tables 20 of the mounting tables 20a-line on the lower side of the photovoltaic power generation panel 10, an area covered with the light _emitting material 30: By setting the area ratio of the uncovered region to about 7 to 3: 3 to 7, preferably about 6 to 4: 4 to 6, and more preferably about 5: 5, the light emission efficiency such as reflection of dead space can be improved. In addition, both of the above effects can be achieved while giving priority to cooling efficiency. Further, in a _region between the two mounting tables 20 of the mounting table connecting rows 20a-line of the mounting tables 20 between the photovoltaic power generation panels 10, an area covered by the light _emitting material 30: By setting the area ratio of the non-covered region to about 7 to 3: 3 to 7, preferably about 6 to 4: 4 to 6, and more preferably about 5: 5, the light emission efficiency such as reflection in an empty space is obtained. And both of the above effects can be achieved while giving priority to cooling efficiency. On the lower side of the photovoltaic power generation panel 10, the lower area near the upper end side of the slope is covered with the light emitting material 30, and the lower end side 12 a is not covered with the light emitting material 30. The above effect may be achieved by covering about 30 to 70% of the area immediately below the solar power generation panel 10.

  The light emitting material 30 may be a reflecting material that reflects and / or scatters sunlight, a fluorescent material that emits fluorescence by sunlight, or a light emitting material that emits light by sunlight.

  The light emitting material 30 is preferably white or glossy. The material for the light emitting material 30 is not particularly limited as long as it can reflect sunlight, but is not particularly limited to ABS resin (acrylonitrile-butadiene-styrene copolymer resin), PE resin (polyethylene resin), specifically high-density polyethylene. White plastic material such as PP resin (polypropylene resin), PC resin (polycarbonate resin), Si resin (silicone resin); Metal material with metallic luster such as stainless steel; Oxidation with white gloss such as alumina Metal material: White material containing a reflective filler such as alumina, magnesium oxide, titanium oxide, zirconium oxide, mica, silica, glass powder, inorganic hollow particles, metal flakes, and metal powder in the resin; Ceramic material; white ceramic material; synthetic resin fabric material; any of them Combinations material; and fluorescent agent to them one, white colorant, and those which are formed of a material containing a white pigment, and / or metal powders.

  The shape of the light emitting material 30 is not particularly limited as long as it can reflect sunlight and exhibits a cooling effect from the water surface. For example, as shown in FIG. Flat plate (Fig. (A)), Reflector with multiple reflective hemispheres vertically and horizontally (Fig. (B)), Reflector with multiple parabolic bowls vertically and horizontally (Fig. (C)), Square prism , Such as a prismatic reflective rod (Fig. (D)), a cylindrical reflective rod (Fig. (E)), an upward semi-cylindrical reflective rod (Fig. (F)), upward one side or both sides Reflective tape consisting of a resin band with a metal thin film ((g) in the figure), a light-scattering or light-reflecting reflector having an exposed lens, encapsulating lens, capsule lens, or prism lens (see FIG. )), A white colorant, a white pigment, a white filler or glossy filler such as metal powder, or a plate of the above-mentioned shape containing a fluorescent agent (FIG. (I)), Connected body in which a hole opened in the center of a projectile spherical body, bale-shaped body, and donut-shaped body is connected with a wire or rope ((j) in the same figure), and a connected body in which floating floating rings are connected with a wire or rope (Fig. (K)), knitting with nets and reflection bands crossed vertically and horizontally (Fig. (L)), flat plates with vertical and horizontal holes (Fig. (M)), sheets (Fig. (N)), And any combination thereof. When the light emitting material 30 is flat, it is easy to produce and attach and easily reflects or scatters, and has at least a curved portion to reflect or scatter various angles of various sunlight, The light receiving efficiency on the back surface 10b side of the solar panel 10 can be increased.

  As shown in FIG. 1 and FIG. 2, the light emitting material 30 is shown as an example in which the light emitting material 30 is intermittently arranged. A sheet that has a space and is arranged on the entire lower surface of the solar panel 10 and has a gap as shown in FIG. 3 (m) or a sheet without a gap as shown in FIG. 3 (n) may be used. .

  When the installation unit 1 of the photovoltaic power generation panel is used on water, the installation base 20 is provided with a photovoltaic power generation system as shown in FIGS. 1, 2, 4 (a) to (e), and FIG. The bridge bar 40 on which the gantry 13 supporting the panel 10 is mounted is placed over the bridge bar 40, and is placed floating on the water. The pedestal 20 has a buoyancy sufficient to place the bridge bar 40 on which the photovoltaic panel 10 and the gantry 13 are mounted, and not to sink even if a security staff gets on because the interior of the cavity of the pedestal 20 is empty. The material and shape are not particularly limited as long as they have the following.

  When the installation unit 1 of the solar panel is used on land or on a building, the installation table 20 is placed on land (ground) or on the surface of the building as shown in FIG. It will be installed. The material and shape of the mounting table 20 are not particularly limited as long as the hollow space is completely or partially filled with a fluid, such as water, so that the mounting table 20 becomes a weight and can hold the fluid.

  The mounting table 20 is formed of, for example, an ABS resin or a PE resin. It is preferable that the mounting table 20 be white or glossy, since the reflectivity is improved and the sunlight irradiated on the mounting table 20 can be received on the back surface 10b side of the photovoltaic power generation panel 10. The mounting table 20 contains a reflective filler such as alumina, magnesium oxide, titanium oxide, zirconium oxide, mica, silica, shell powder, inorganic hollow particles, metal flakes, etc., to make it white or glossy, to reflect light, etc. May be increased in light emission efficiency.

  Even if the installation base 20 reflects or scatters sunlight on the back surface 10b side of the photovoltaic power generation panel 10 together with the light emitting material 30 or in place of the light emitting material 30, the power generation efficiency is improved. Good.

  The mounting table 20 is, for example, a substantially symmetrical rectangular body having a groove 23 in which the center of the long side is recessed inward along the short side direction. Along this groove 23, there are half body portions formed symmetrically on both sides thereof. When the installation unit 1 of the photovoltaic power generation panel is used on water, a wave-proof part having a curved shape or a wavy shape may be provided on a side surface of the installation table 20, for example, on a long side surface (not shown). ). The wave-preventing section buffers the waves on the water surface, and prevents large swaying of the installation stand 20 together with the photovoltaic power generation panel 10, the pedestal 13, and the bridge bar 40.

  The groove 23 has such a depth that the bridge bar 40 can be fitted and fitted. The bridge bar 40 has an L-shaped, U-shaped, or R-shaped cross section, and a part of the bridge bar is fitted in the groove. Preferably, the upper end or the upper surface of the bridge bar 40 is flush with the upper end or the upper surface of the installation stand, or lowers from the upper end or the upper surface of the installation stand by the thickness of the installation stand connection bar 27, the installation stand bridge bar 28, and the washer. It is almost the same height. Since the upper end or upper surface of the bridge bar 40 is at the same height or approximately the same height as the upper end or upper surface of the installation stand, the bridge bar 40 does not protrude from the groove 23, so that when walking on the installation stand Do not stumble. A groove collar 22b extends from an end of the groove 23. A hole is formed in the groove collar 22b at a position corresponding to the bolt hole formed in the bridge bar 40. In this groove 23, a bridge bar 40 is locked and fastened with bolts and nuts.

  The installation base 20 has an end-side flange 22a having the same height as the upper surface extending to the short side of one end of the half body (the left half body in FIG. 5A) and the vicinity of the corner. At the short side of the end of the other half body (the right half body in FIG. 5 (a)) and near the corner, the thickness of the flange 22a of the left half body from the upper surface and, if necessary, the installation stand connecting bar 27 and the installation stand bridge At a position lowered in the height direction by the thickness of the bar 28 or the washer, a flange 22c extends to the short side of the end and the vicinity of the corner. Each of the flanges 22a, 22b, and 22c has at least two holes on the short side for fastening and locking the adjacent installation tables 20 with bolts and nuts. In addition, each of the flanges 22a, 22b, and 22c has a hole for connecting the adjacent installation tables 20 by fastening and locking the adjacent installation tables 20 with bolts and nuts using an installation table connection bar 27 and an installation table bridge bar 28. , At least one is open on the side of the feature length. The flanges 22a and 22c extending from the left and right bodies, respectively, are stepped, so that the adjacent installation tables 20 can be connected to each other so that no step is formed on the upper surface. Thereby, the installation bases 20 can be connected vertically and horizontally, and a large number of the solar power generation panels 10 can be stably installed on the wavy water or on the blowing wind on the land or on a building in a wide area. Such a mounting table 20 can be formed by blow molding, or can be formed by integrally forming the upper half and the lower half by injection molding and then by heat welding.

  The example in which the installation table 20 has one groove 23 (see FIGS. 1, 2, and 4 (a)) shows the type of the photovoltaic panel 10 having a different number of the cells 11 made of the solar cell elements ( For example, it has a plurality of grooves 23a, 23b, 23c that can bridge the bridge bar 40, corresponding to their length and / or width according to the photovoltaic panels 10) of 60 cells or 72 cells, for example. (See FIG. 4B). Thereby, regardless of the type of the photovoltaic power generation panel 10, the installation unit 1 of the photovoltaic power generation panel 10 can be freely manufactured with one type of the installation base 20.

  As shown in FIG. 4C, the mounting table 20 may be provided with a hole 24b that is recessed from the bottom surface toward the inner side surface of the groove 23 at the center of the groove 23. Further, holes 24a and 24c that are recessed from the bottom surface toward the inner surface of the top surface may be provided at the center of the left and right bodies. These holes 24a, 24b, and 24c are non-penetrating and have a cylindrical or truncated conical shape, so that even if they have a single or a plurality of hollow chambers, they have a resistance to a load in the height direction. Increase. These holes 24a, 24b, and 24c may be depressed until they come into contact with the inner surface of the bottom of the groove 23 or the inner surface of the top surface, but may not be in contact with some play. The presence of these holes 24a, 24b, and 24c increases the strength that will not be depressed when walking on the connected mounting table 20. Therefore, even when walking on the installation table, the installation table does not dent with weight, and can resist load resistance. When it is in contact, the upper surface of the installation table 20 does not physically bend when walking on the installation table 20, and the installation table 20 is not damaged. On the other hand, if there is no contact with some play, when walking on the installation table 20, the upper surface of the installation table 20 bends up to the maximum abutment, so that the installation table 20 is buffered and is not damaged. Such a mounting table 20 can be formed by blow molding, or can be formed by integrally forming the upper half and the lower half by injection molding and then by heat welding.

  When the plurality of installation bases 20 are connected, their positions are adjusted so that the grooves 23 just bridge one bridge bar 40 for each photovoltaic power generation panel 10.

For example, an inlet cap 21a for closing an inlet for injecting an appropriate amount of water and an outlet cap 21b for closing an outlet for discharging the water may be provided. Thereby, the installation table 20 becomes a weight when installing the installation unit 1 of the photovoltaic power generation panel on land or on a building, for example, on the roof, but drains water immediately before the waterproof re-installation on the roof due to aging. After disassembling and moving the installation unit 1 of the photovoltaic panel, the waterproof unit can be easily re-installed after the waterproofing and rebuilding.

  The mounting table 20 may have a single hollow chamber, or may have a plurality of independent hollow chambers 25a to 25e. As a result, cracks may occur in any of the hollow chambers 25a to 25e due to deterioration over time due to direct sunlight or salt damage due to long-term installation, or breakage may occur due to contact with drifting objects or dropping of tools during inspection. In other words, if the other cavities 25a to 25e are not damaged, inundation damage can be minimized and floating can be continued, or water leakage can be reduced to only the cavities and used as a weight. This can be continued (see FIG. 4 (e)). The mounting table 20 having such a plurality of hollow chambers 25a to 25e is one in which the upper half and the lower half are formed by injection molding and then integrated by heat welding. The side walls of the plurality of hollow chambers 25a to 25e also contribute to an increase in resistance to a load in the height direction.

  The mounting table 20 may be provided with a non-slip surface on an upper exposed surface. The non-slip may be rubber attached to a part of the upper surface of the mounting table 20, and may have a rectangular parallelepiped shape placed on the upper surface of the mounting table 20, a shape in which the upper part of the rectangular parallelepiped is cut obliquely, a wedge shape, and an arc shape. Block pieces arranged vertically and horizontally with dots or triangular prism-shaped block pieces arranged along the long side of the mounting table 20 may be used (not shown). By adopting such a shape, it is possible to improve the antireflection effect and the reflectivity of the photovoltaic panel 10 on the back surface 10b. In particular, it is preferable that the upper side of the rectangular parallelepiped is a block, a wedge shape, or a triangular prism-shaped block that is obliquely cut so that reflected light from sunlight is received on the back surface 10b of the solar power generation panel 10.

  The installation table 20 may be provided with a curved / wave-shaped wavebreaker on the side surface on the long side (not shown). As shown in FIG. 5 (a), the installation table 20 may be a marker for indicating the installation direction, for example, a triangle mark.
