Description

Installation unit of solar power panel and solar power array connecting it

The present invention relates to an installation unit for installing solar power panels arranged with a plurality of cells having solar cell elements capable of generating electricity on both sides on water, land, and buildings to improve power generation efficiency and to install the solar power panel Connect multiple solar power arrays.

Power generation using fossil fuels, such as oil-fired power generation and natural gas-fired power generation, will produce carbon dioxide, which accelerates global warming. In addition, nuclear power generation has problems such as the danger of large-scale accidents, or the disposal of massive amounts of radioactive waste. Therefore, in recent years, there has been a shift toward power generation using clean energy such as solar power, wind power, or hydropower.

Among them, solar power generation has been widely used from commercial power generation on a wide range of land to small-scale power generation on the roofs of residential buildings.

Commercially, solar power generation is carried out by installing solar panels on land, roofs, and other buildings in fallow land or wilderness, or on water such as lakes and marshes, flood detention areas, or the sea. When it is installed on land, it is difficult to secure a wide area of land in addition to the need for construction and construction. Once installed, it can only be used for power generation purposes, but it has the advantage of being able to effectively use fallow land or wilderness. In addition, when it is installed on a building, it has the advantage of being flat and easy to construct, and it can effectively use land that is not normally used. On the other hand, when it is installed on the water, it has the following advantages: it does not require construction and can secure a wide water area at low cost. Even if it is installed, it can be used for fishery, agriculture, water storage or water adjustment, etc. to use the water area. The purpose can also continue to be used concurrently.

Patent Document 1 discloses a solar power generation unit that holds a solar power generation panel on the water to generate power, and includes: a solar power generation panel; and a corridor plate having a rectangular shape when viewed from above. The corridor plate is formed in the following manner: A floating raft with a rectangular shape in plan view with a holding portion for holding the solar power generation panel on the surface, and a non-slip convex portion on the back side opposite to the aforementioned surface for walking, so that the front side is floated on the water to hold the solar power generation panel The aforementioned floating raft, and the aforementioned floating raft that floats the back surface on the water and connects a plurality of buoyant bodies that generate buoyancy and the steps and passages are held by a recess provided in the center of the long side of the back side so that the front side floats on One end of the short side of the floating raft that holds the solar power panel on the water.

In solar power generation, if the temperature of the solar power panel rises too much, it will cause a decrease in power generation. Especially in solar power generation on land or buildings closely connected with solar power panels in hot weather and under no wind, the inside of the solar power panels can rise to a maximum of 70-80°C. It is said that its internal temperature is at the highest power generation efficiency around 25°C, and the power generation efficiency will decrease by 0.5% for every 1°C rise.

Solar power generation on water is not easy to cause the temperature of the solar power generation panel to rise due to the cooling effect from the water surface, so the power generation efficiency is better than that on land. However, even on the water, if the solar power generation panels are arranged densely in order to increase the power generation efficiency per unit area, the ventilation will deteriorate and the cooling efficiency will decrease, which will lead to a decrease in the power generation efficiency.

In the solar power generation on water, the pursuit of a way to further improve the power generation efficiency of each solar power panel, and to further improve the power generation efficiency per unit area, and can be simply installed, and easy to maintain and manage even on unstable water The installation unit of the solar power panel on the water and connect it to a plurality of solar power arrays.

In addition, in solar power generation on land or buildings, the same is true for solar power generation that can improve power generation efficiency, maintain cooling effects, can be easily installed, and can be easily moved and reinstalled during roof waterproofing and re-construction. The installation unit of solar power panels on land or buildings and connect them to multiple solar power arrays.

In addition, from the viewpoint of production cost reduction, a solar power generation panel installation unit and a solar power array that use the same solar power panel installation unit and can be installed on water, land, and buildings are expected.

The framework of the system. Although the power generation of the commercially available solar power panel 10 varies slightly depending on the solar light receiving efficiency of the front 10a and the scattered light/reflected light of the rear 10b, the total output of both sides is about 290～ 310 W persons.

In order to improve the power generation efficiency, the solar power generation panel 10 capable of generating power on both sides is installed obliquely so as to face the sunlight in the south direction. In the case of a fixed tilt angle, the orientation and angle are adjusted in such a way that the front face 10a of the solar power panel 10 faces the sunlight for the longest time. The gantry 13 is pivotally supported by the rotating shaft 41 on the gantry 13 in such a way that the lower end side 12a of the frame is pivoted as shown by the arrow in FIG. 1 so that the solar power generation panel 10 can be easily maintained and managed on the back side 10b. The solar power generation panel 10 may be a sun tracking type. Each solar power panel 10 in each panel row 10 _line of the solar power panel 10 can be arranged almost without gaps, or can be arranged with gaps open.

The solar power generation panels 10 are respectively supported and connected by the upper frame beam 14 and the lower frame beam 16 to form a panel row 10 _line , and a plurality of installation stands 20 are _{connected along the panel row 10 line} by installation stand connecting rods 27 to form line connection setting table 20a _-line, and the groove 20 of such sets is provided (sectional view taken along (a) AA-line arrow in FIG. 4, FIG. 5 (a)) 23 are embedded with a tray 40, provided in the connection table rows 20a _- respective end of the _line, the other table 20 is provided in a manner such orthogonal, the table is provided by the bridge 28 bridges the rod to become disposed bridge line station 20b _-line, and the connecting rod 27 is fixed stations. The installation stand connecting rod 27 and the installation stand bridge rod 28 are, for example, an L-shaped metal angle member in cross section.

The solar power panels 10 capable of generating electricity on both sides are supported one by one and fixed on the stand 13. The stand 13 of each solar power panel 10 is placed on the bridge 40, and the panel rows 10 _{lines of} each row of solar power panels 10 are clamped between the setting stands 20 is provided between the connecting lines 20a _-line station, station set connected to the line 20a _-line disposed central station 20 of the groove 23 of each of two pairs of each other, the erection and placement of each tray 40.

At a position lower than the solar power panel 10, and at a specific location on the water/land (on the ground) or on the surface of a building, intermittently arrange a reflective material that reflects sunlight toward the back 10b of the solar power panel 10, that is, light Shooting material 30. A light emitting member 30 is bridged setting table 20 of the table row 20a _-line connected to each other two pairs of units 20 disposed in such manner and / or in each erecting a solar photovoltaic panel 40 of the tray 10 is provided. For example, as shown in FIG. 1 and FIG. 2, the light emitting panel member 30 and parallel line 10 _line 10 _line is slightly longer than the panel row, the 10 _line as to bridge the full erection of the panel row 40 is provided.

The light beam 30 is a material that effectively utilizes the dead space of the installation unit 1 of the solar power panel 10, so that it does not directly irradiate the front surface 10a of the solar power panel 10 and passes between the solar power panels 10 to reach the water surface. The sunlight in the direction is a reflective material that reflects and/or scatters toward the back surface 10b of the solar power generation panel 10, and is used to improve the power generation efficiency. By disposing intermittently together with the other, the cooling effect of the solar power generation panel 10 from the water surface can not be reduced so much. The light emitting material 30 may also be a reflective material, a fluorescent material that uses sunlight for fluorescent light, or a light emitting material that uses sunlight to emit light. The light emitting material 30 may also be a combination of at least any one of a reflective material, a fluorescent material, and a luminous material. By disposing such light emitting materials 30 intermittently, it can take into account that the wider the range of the reflecting member, the better the light emitting efficiency of reflection, etc. The narrower the range of the reflecting member, the better the ventilation and the cooling effect from the water surface. The better the opposite effect.

A light emitting member 30 is provided disposed beneath the side of the solar photovoltaic panel 10 of the station 20 sets the connection line 20a _-line another region disposed between the two pairs of the table 20, and disposed between the solar photovoltaic panel of another set 20 of 10 station connected to line 20a _-line region 20 between the two pairs of each other station set, by the light emitting area 30 of the covering member: the area of the non-coated area of the light emitting member 30 is set to the same ratio of both, may set different . For example, under the setting side of the solar photovoltaic panel 10 of the station 20 sets the connection line 20a _-line another region disposed between the two pairs of units 20, by the light emitted by the covering member 30 of the region: a light emitting member 30 The area ratio of the uncovered area is set to about 7～3:3～7, preferably about 6～4:4～6, more preferably about 5:5, so that the cooling efficiency can be lower than the reflection of ineffective space. The light emission efficiency is more prioritized, and the aforementioned two effects are taken into consideration. Further, in the solar photovoltaic panel is provided disposed between the table 20 of the table 10 to each other are connected with one another row 20a _-line region disposed between the two pairs of units 20, by the light emitted by the covering member 30 of the region: a light emitting member 30 The area ratio of the uncovered area is set to about 7～3:3～7, preferably about 6～4:4～6, more preferably about 5:5, so that the cooling efficiency can be better than the reflection of the empty space. The light emission efficiency is more prioritized, and both the aforementioned two effects are taken into consideration. In addition, on the lower side of the solar power generation panel 10, it is possible to set the area near the lower side of the inclined upper end edge portion to be covered by the light emitting material 30, and to set it close to the inclined lower end edge 12a as the light emitting material The uncovered area of 30 is covered by about 30-70% relative to the area directly under the solar power panel 10, while taking into account the aforementioned two effects.

The light emitting material 30 is not only a reflective material that reflects and/or scatters sunlight, but also a fluorescent material that uses sunlight for fluorescent light, and a luminous material that uses sunlight to emit light.

The light emitting material 30 preferably has whiteness or glossiness. As the light emitting material 30, if it is capable of reflecting sunlight, the material is not particularly limited. Examples include those made of the following materials, such as ABS resin (Acrylonitrile-butadiene-styrene (Acrylonitrile-butadiene) -styrene) copolymer resin), PE resin (polyethylene resin), specifically high-density polyethylene, PP resin (polypropylene resin), PC resin (polycarbonate resin), Si resin (silicone resin), etc. Plastic materials; metallic luster metal materials such as stainless steel; white luster metal oxide materials such as alumina; the aforementioned resin contains such as alumina, magnesia, titanium oxide, zirconia, mica, silicon dioxide, White materials with reflective fillers such as glass powder, inorganic hollow particles, metal flakes, and metal powder; white ceramic materials; white ceramic materials; synthetic resin cloth materials; any combination of these materials; and One contains materials containing fluorescent agents, white colorants, white pigments, and/or metal powders.

The shape of the light emitting material 30 is not particularly limited if it can reflect sunlight and exhibit a cooling effect from the water surface. For example, as shown in FIG. 3, as a plurality of intermittently arranged ones, there may be mentioned: reflection Flat plate (Figure 3(a)), a reflector with multiple reflective hemispheres horizontally and vertically (Figure 3(b)), and a reflector with multiple parabolic bowls horizontally and vertically (Figure 3(c)), such as a quadrangular column The angular cylindrical reflector rod (Figure 3(d)), the cylindrical reflector rod (Figure 3(e)), the upward semi-cylindrical reflector rod (Figure 3(f)), upward and on one side Or a reflective tape with a metal film on both sides, including a resin tape (Figure 3(g)), with a light-scattering or light-reflective reflector that exposes the lens/enclosed lens/capsule lens or the prism lens (Figure 3(g)) 3(h)), the plate of the aforementioned shape containing white colorant, white pigment, metal powder, white filler or gloss filler, or fluorescent agent (Figure 3(i)), will be a reflective spherical body/ The hole in the center of the bag/ring is connected by a cable or rope (Figure 3(j)), and the floating ring is connected by a cable or rope (Figure 3(k)) ), a braid that crosses the net or reflective tape horizontally and vertically (Figure 3(l)), a flat plate with holes horizontally and vertically (Figure 3(m)), a sheet (Figure 3(n)), and any of these The combination of those. If the light emitting material 30 is flat, it can be easily manufactured and installed to reflect or scatter efficiently, and if it has at least a curved portion, it can reflect or scatter various angles of sunlight, which can be improved on the back 10b side of the solar power panel 10 The light-receiving efficiency.

As the light emitting material 30, an example of intermittent arrangement as shown in Figs. 1 and 2 is shown, but it may also have a space between the stand of the solar power panel 10 and the back surface 10b of the solar power panel 10 by obliquely supporting it. And it is arranged on the entire surface under the solar power generation panel 10, such as a sheet with gaps as shown in FIG. 3(m) or a sheet without gaps as shown in FIG. 3(n).

When the installation unit 1 of the solar power panel is used on water, the installation stand 20 is as shown in Figure 1, Figure 2, Figure 4 (a) ~ Figure 4 (e), Figure 5 (a), the installation site The bridge 40 equipped with the stand 13 supporting the solar power generation panel 10 is mounted, and the bridge 40 is installed floating on the water. If the installation table 20 is a bridge 40 on which the solar power generation panel 10 and the stand 13 are mounted, and the cavity of the installation table 20 is empty and has a buoyancy that does not sink even if the security personnel board, the material or shape is not There is no particular limitation.

In addition, when the installation unit 1 of the solar power generation panel is used on land or on a building, the installation stand 20 is installed on the land (on the ground) or on the surface of a building as shown in the figure. The installation table 20 becomes a heavy object by completely filling its cavity with a fluid, such as water, or filling it in the middle. If the fluid can be maintained, the material or shape is not particularly limited.

The installation table 20 is formed of, for example, ABS resin or PE resin. If the installation table 20 is white or even glossy, the reflectivity is improved, and the sunlight irradiated to the installation table 20 can be received on the back surface 10b side of the solar power generation panel 10, which is preferable. The setting table 20 may contain reflective fillers such as alumina, magnesia, titania, zirconia, mica, silica, shell powder, inorganic hollow particles, metal flakes, and be set to whiteness and glossiness, thereby improving Light emission efficiency such as reflection.

The installation table 20 can be used together with the light emitting material 30 or instead of the light emitting material 30 to reflect or scatter sunlight on the back side 10b of the solar power generation panel 10 to improve the power generation efficiency.

The installation base 20 is, for example, a substantially rectangular parallelepiped having a left-right symmetrical groove 23 with the center of the long side recessed toward the inner hollow side along the short side direction. Along the groove 23, there are halves formed symmetrically on both sides thereof. When the installation unit 1 of the solar power generation panel is used on water, a curved or wave-shaped wave-proof part (not shown) may be provided on the side surface of the installation table 20, such as the side surface of the long side. The anti-wave part buffers the waves on the water surface, and prevents the installation platform 20 together with the solar power generation panel 10, the stand 13, and the bridge 40 from shaking greatly.

The groove 23 forms the depth at which the bridge 40 is just inserted and accommodated. The aforementioned cross-section of the bridge frame 40 is set in an L-shaped, U-shaped, or B-shaped shape, and a part of the bridge frame is embedded in the aforementioned groove. Preferably, the upper end or upper surface of the bridge 40 is at the same height as the upper end or upper surface of the installation platform, or the installation platform connecting rod 27 or the thickness of the installation platform bridge rod 28 or gasket is lowered from the upper end or upper surface of the installation platform The shares are roughly the same height. The upper end or the upper surface of the bridge 40 is formed to be the same height or substantially the same height as the upper end or the upper surface of the installation platform, and the bridge 40 does not protrude from the groove 23, so that it will not trip when walking on the installation platform. The groove flange 22b extends from the end of the groove 23. The groove flange 22b is provided with a hole at a position corresponding to the bolt locking hole opened in the bridge 40. In this groove 23, the bridge 40 is fastened by bolts and nuts to be locked.

In the setting stand 20, a flange 22a on the end side of the same height as the upper surface extends near the short side and the corner of the end of one half of the body (the left half of the body in FIG. 5(a)). In the other half of the body (Figure 5(a), the right half of the body) near the short side and its corners, the thickness of the flange 22a of the left half of the body is reduced in the height direction compared to the upper surface. The rod 27 or the position where the thickness of the gantry bridge rod 28 or the washer is set has a flange 22c extending near the short side and the corner of the end. In each flange 22a, 22b, 22c, at least two holes are opened on the short sides for fastening the adjacent installation tables 20 to each other by bolts and nuts. In addition, on each flange 22a, 22b, 22c, at least one is provided on the long side for connecting the adjacent installation platforms 20 to each other by the installation platform connecting rod 27 or the installation platform bridge rod 28 with bolts and nuts. A hole that is connected in a solid and locked way. Since the flanges 22a and 22c extending from the left and right half of the body form a step shape, the adjacent installation platforms 20 can be connected to each other without a step difference on the upper surface. In this way, the installation stands 20 are connected horizontally and vertically, and a large number of solar power generation panels 10 can be stably installed on undulating water, wind-blown land or buildings in a wide range. Such an installation stand 20 may be formed by blow molding, or after the upper half and the lower half are formed by injection molding, they can be integrated by thermal welding.

The setting table 20 has a groove 23 (refer to Figure 1, Figure 2 and Figure 4 (a)), but it can also be based on the types of solar power panels 10 (such as 60 cells, 60 cells, Or the 72-cell solar power generation panel 10) corresponding to the length and/or width thereof, has a plurality of grooves 23a, 23b, 23c (refer to FIG. 4(b)) where the bridge 40 can be erected. Thereby, regardless of the type of the solar power generation panel 10, the installation unit 1 of the solar power generation panel 10 can be freely manufactured using one type of installation stand 20.

As shown in FIG. 4( c ), the setting table 20 may also be provided with a hole 24 b recessed from the bottom surface toward the inner surface of the bottom of the groove 23 in the center of the groove 23. In addition, holes 24a, 24c recessed from the bottom surface toward the inner side surface of the top surface can also be provided in the center of the left and right half of the body. The holes 24a, 24b, and 24c are non-penetrating, and by being formed into a cylindrical shape or a truncated cone shape, even if they have a single or a plurality of cavities, the resistance against the load in the height direction is increased. The holes 24a, 24b, and 24c can be recessed to abut against the inner surface of the bottom or the top surface of the groove 23, or they can have a slight clearance without abutting. If the holes 24a, 24b, and 24c are provided, the strength that does not sink even when walking on the connected installation platform 20 is increased. Therefore, even when walking on the installation table, the installation table does not sink due to body weight, but can resist the load resistance. If it abuts, when walking on the installation table 20, the upper surface of the installation table 20 does not physically bend, and the installation table 20 is not damaged. On the other hand, if there is a slight play and not abutting, when walking on the installation table 20, the upper surface of the installation table 20 will bend to the maximum abutment to buffer the installation table 20 without damaging the installation table 20. Such an installation table 20 may be formed by blow molding, or after the upper half and the lower half are formed by injection molding, they can be integrally formed by thermal welding.

When a plurality of installation stands 20 are connected, the positions are adjusted in such a way that the grooves 23 just erect one bridge 40 of each solar power panel 10.

As shown in (refer to FIG. 4(d)), the installation stand 20 may have an injection port cover 21a in order to function as a heavy object when the installation unit 1 of the solar power generation panel is used on land or on a building.

Thereby, the installation platform 20 becomes a heavy object when the installation unit 1 of the solar power generation panel is installed on the land or on a building, such as a roof, but it can be drained immediately before the waterproofing of the roof due to time-deterioration is re-construction. Moreover, after disassembling and moving the installation unit 1 of the solar power generation panel, after waterproofing and re-construction, simply reset the installation unit 1 of the solar power generation panel.

The setting table 20 may have a single hollow chamber, or may have a plurality of independent hollow chambers 25a-25e. As a result, even in any of the cavities 25a-25e, cracks caused by direct sunlight or salt damage due to chronological deterioration due to long-term installation, or due to contact with drifting objects or tools dropped during inspection The damage is caused by this, but because the other cavities 25a-25e are not damaged, the damage from flooding can be minimized and continue to float, or the damage from water leakage can be limited to the cavity and continue to be used as a heavy object ( Refer to Figure 4(e)). The installation table 20 having such a plurality of cavities 25a-25e is formed by injection molding the upper half and the lower half, and then integrating them by thermal welding. In addition, the side walls of such a plurality of cavities 25a-25e also contribute to increase the resistance to the load in the height direction.

The setting table 20 can apply anti-skid substances on the exposed surface of the upper part. The anti-skid material may be rubber attached to a part of the upper surface of the setting table 20, or it may be a rectangular parallelepiped shape placed on the upper surface of the setting table 20, a shape in which the upper side of the rectangular parallelepiped is cut obliquely, a wedge shape, or an arc shape. The point is on the block pieces arranged horizontally and vertically, and the triangular column-shaped block pieces (not shown) are arranged horizontally along the long side of the setting table 20. By using such a shape, the anti-slip effect is achieved, and the reflectivity toward the back surface 10b of the solar power generation panel 10 is improved.
