Description

The present invention relates to a solar sharing system that performs farming (cultivating crops) and solar power generation on the same land. and power generation efficiently.

Due to the increasing use of clean energy, a solar sharing system that aims to simultaneously perform farming and power generation using fallow farmland is attracting attention.

This type of solar sharing system simultaneously performs farming and power generation by providing a lighting unit and solar panels on cultivated land where crops are grown. For example, if solar panels with a width of 1000 mm are arranged alternately with respect to a light receiving part with a width of 1000 mm, the light receiving area and the power generation area become one to one. In some cases, the width of the solar panel is set to "2" or "3" with respect to the width of the lighting section of "1". Moreover, when emphasizing farm management, the width of the solar panel may be set to "1" with respect to the width of the lighting section of "3". If the area of the solar panel is large, the amount of light coming in from the light receiving area will decrease, and the lack of illuminance will hinder farming. stay up.

In addition, when direct light is taken in from the lighting part, strong straight light (about 70,000 lux in winter and 140,000 lux in summer) is irradiated only on a part of the crop, and the irradiated part moves as time passes. However, the crops directly under the solar panel were not irradiated so much (about 0.8 to 12,000 lux), and the uniform illuminance was not obtained, which had a negative impact on the growth of the crops. In addition, there is also the problem that when crops grow tall, the upper part of the crop will not receive light and will not grow.

As a solar sharing system using a light diffusing plate in the light receiving part, Patent Documents 1 and 2 disclose a solar sharing system in which a plurality of power generating bodies are attached in a solar panel to generate power, and a light diffusing plate is attached to the gap between these power generating bodies. A solar sharing system is disclosed in which a section is created and the sunlight passing through the lighting section is used to grow crops under the panel.

JP 2018-082133 A Japanese Patent No. 5960332

According to the solar sharing systems described in Patent Documents 1 and 2, by attaching a planar diffuser plate to the lighting section provided between the power generation bodies, the intensity of the light between the shaded part and the sunlit part by the power generation bodies is increased. The difference in height is reduced, and the growth inhibition of crops due to the intensity of light can be prevented to some extent.

However, as in these solar sharing systems, simply providing a planar diffuser plate in the gap between the power generating bodies does not sufficiently diffuse the sunlight passing through the translucent part, and the light intensity varies. There is an inconvenience that the light is applied to the crops (cultivated plants) under the panel. Especially in mid-high latitude regions like Japan, where the altitude of the sun varies greatly depending on the season, the angle of incidence of the sunlight applied to the translucent part varies depending on the season. It was difficult to feed the crops. In addition, since the angle of incidence of sunlight applied to the translucent portion varies depending on the time of day, it has been difficult to provide sufficiently diffused light to the crops under the panel throughout the day.

Further, according to the solar sharing systems described in Patent Literatures 1 and 2, it is difficult for rainwater to uniformly drop from the lighting section and the tip of the power generation body. This is caused by the fact that it is difficult to install the solar panel so that the tip of the solar panel is completely horizontal, and rainwater runs off in one direction due to the influence of the wind and the hydrophilicity of rainwater. Therefore, it was not possible to uniformly water the crops under the power generation panels.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a solar sharing system capable of illuminating the crops under the photovoltaic panels with uniform light throughout the seasons of the year or throughout the hours of the day.

Another object of the present invention is to provide a solar sharing system capable of uniformly pouring rainwater onto the crops under the photovoltaic panels.

According to the present invention, a solar sharing system includes a plurality of photovoltaic panels and a plurality of light diffusion members that are provided between the plurality of photovoltaic panels and diffuse sunlight. The plurality of light diffusing members are installed so as to be inclined downward toward one end of the solar sharing system, and have a corrugated plate shape with the flow direction along the direction of the inclination.

Due to the corrugated shape of the light diffusing member, the light is diffused not only downward but also laterally over a wider angle. improves. As a result, light with a more uniform intensity distribution that is well diffused throughout the seasons of the year or throughout the hours of the day irradiates the crops under the photovoltaic panels with a more uniform intensity distribution. Become. Furthermore, since the solar panel is installed with a downward inclination toward one end and the flow direction is along the direction of the inclination, the rainwater is evenly poured onto the crops under the solar power generation panel. .

It is preferable that the plurality of photovoltaic panels be installed with a downward inclination toward one end of the solar sharing system, and have a corrugated plate shape with the flow direction along the inclination direction. As a result, the light-receiving area of the photovoltaic panel is increased, and the power generation efficiency is greatly improved. Furthermore, since the flow direction of the corrugated plate is along the direction of its inclination, the rainwater is evenly poured onto the crops under the photovoltaic panel.

It is also preferable that through-holes are provided at predetermined intervals in the flow direction in the bottom of each valley of the plurality of light diffusing members. In this case, when the length of each of the plurality of light diffusing members in the flow direction exceeds 1000 mm, the predetermined interval is more preferably about 400 mm to about 1000 mm.

It is also preferable that through-holes are provided at predetermined intervals in the flow direction in the bottom of each valley of the plurality of solar panels. In this case, when the length of each of the plurality of light diffusing members in the flow direction exceeds 1000 mm, the predetermined interval is more preferably about 400 mm to about 1000 mm.

It is also preferable that the plurality of photovoltaic panels and the plurality of light diffusion members have gaps of a predetermined length in the flow direction. More preferably, the predetermined length in this case is about 20 mm.

It is also preferable that the plurality of photovoltaic panels and the plurality of light diffusion members are inclined at a gradient of 3/100 to 30/100.

It is also preferable that the plurality of photovoltaic panels and the plurality of light diffusing members are installed with a downward inclination toward the south direction in the northern hemisphere and toward the north direction in the southern hemisphere.

Alternatively, it preferably has a length in the machine direction of about 500 mm to about 1000 mm and a width of about 900 mm to about 2000 mm.

It is also preferable that one row of light diffusion members and one to three rows of photovoltaic panels are alternately arranged.

It is also preferred that the plurality of photovoltaic panels are perovskite solar cells having perovskite films laminated on corrugated substrate panels.

According to the present invention, since the light diffusing member has a corrugated plate shape, the light is diffused not only downward but also laterally at a wider angle. Light diffusibility is greatly improved. As a result, light with a more uniform intensity distribution that is well diffused throughout the seasons of the year or throughout the hours of the day irradiates the crops under the photovoltaic panels with a more uniform intensity distribution. Become. Furthermore, since the panels are installed with a downward inclination toward one end and the direction of flow is along the direction of the inclination, the rainwater is evenly poured onto the crops under the panels.

Note that FIG. 1 shows a cross section taken along the line AA of FIG.

As shown in these figures, in the solar sharing system of this embodiment, a crop (cultivated product) 10 is planted above a cultivated field (or a cultivation tank in the case of hydroponics) 11 supported by a support 12. A plurality of photovoltaic panels (hereinafter referred to as solar panels) 14 and a plurality of corrugated plate-shaped light diffusion members 15 for transmitting and diffusing sunlight are mounted on this frame 13 by mounting bases 16. is set up. A plurality of light diffusion members 15 are provided between the plurality of solar panels 14 . By providing the light diffusing member 15 between the solar panels 14 in this way, the direct light is diffused, the direct light is prevented from irradiating only a part of the crops, and the light is uniformly diffused directly below the solar panel 14. You can let the light in. That is, it is possible to uniformly irradiate the crops under the solar panel 14 from all directions and grow the crops stably. FIG. 1 illustrates the irradiation of crops at the vernal and autumnal equinoxes at a sun altitude of 55 degrees. As described above, if the light diffusing member 15 is not present, the direct light is only partially irradiated. Directly below the solar panel 14, the diffused light from the adjacent light diffusion member 15 intersects and is irradiated. It is desirable that the light diffusing member 15 and the solar panel 14 have the same shape and size, and that they are attached to the mounting frame 16 in the same manner.

In this embodiment, each solar panel 14 is a rectangular flat panel in which silicon-based solar cells or perovskite-based solar cells are provided on a metal substrate such as steel or stainless steel or a resin substrate. The dimensions are only one example, but the width (long side) is approximately 1800 mm and the length (short side) is approximately 600 mm. The width (long side) can be appropriately selected within the range of about 900 mm to about 2000 mm, and the length (short side) can be selected within the range of about 500 mm to about 1000 mm. As a modification, the width (short side) may be approximately 600 mm and the length (long side) may be approximately 1800 mm. In that case, the width (short side) can be selected appropriately within the range of about 500 mm to about 1000 mm, and the length (long side) can be selected within the range of about 900 mm to about 2000 mm.

Each light diffusion member 15 has a rectangular corrugated plate shape. By using the corrugated light diffusing member 15, the surface area increases from about 1.2 times to about 1.5 times. of sunlight can be efficiently diffused and irradiated. Also, the light diffusing member 15 must be inexpensive, tough, and resistant to rain and rain. Furthermore, it is preferable that the transmittance is about 50% to 80% and the diffusion angle is about 60 degrees to 100 degrees, so that the crops immediately below the solar panel 14 can be irradiated with uniform diffused light from north, south, east and west. As a result, even tall crops can be cultivated stably. Therefore, as the light diffusing member 15, a material that is easy to process, has a corrugated plate shape, and transmits and diffuses light is selected from materials that have been used as roofing materials. The corrugated plate shape is generally a folded plate shape, a circular wave shape, or a rectangular wave shape. As a material for transmitting and diffusing light, a polycarbonate material is desirable, but an FRP material may also be used. In addition, it is desirable to use a round-wave type commercial product that is inexpensive, has good weather protection, and is easy to install. Of course, the transmittance and diffusion angle of the light diffusing member 15 are selected in consideration of the installation height, the installation interval, the height of the crops, and the required illuminance. In this embodiment, the light diffusing member 15 is composed of a corrugated polycarbonate panel, and its dimensions are merely an example, but the width (long side) is about 1800 mm and the length (short side) in the flow direction is about 1800 mm. side) is about 600 mm, the peak pitch is about 63 mm, and the peak height is about 18 mm. Specifically, although this is merely an example, polycarbonate corrugated panels, polycarbonate hollow panels (e.g., Polykanami (registered trademark), Polykatwin (registered trademark), Twincarbo (registered trademark), Paircarbo (registered trademark)), etc. light diffusion I am using a panel. Frost type and embossed finish improve diffusion. The width (long side) can be appropriately selected from a range of approximately 900 mm to approximately 2000 mm, the length (short side) from approximately 500 mm to approximately 1000 mm, and the peak pitch from approximately 30 mm to approximately 200 mm. As a modification, the width (short side) may be approximately 600 mm and the length (long side) may be approximately 1800 mm. In that case, the width (short side) can be selected appropriately within the range of about 500 mm to about 1000 mm, and the length (long side) can be selected within the range of about 900 mm to about 2000 mm.

The plurality of solar panels 14 and the plurality of light diffusion members 15 have their length directions (flow direction in the case of corrugated plate shape) in the north-south direction, and in the south direction (south direction in the northern hemisphere, north direction in the southern hemisphere) ) is installed so as to incline downward at a predetermined gradient. In this embodiment, a plurality of solar panels 14 and a plurality of light diffusing members 15 are obliquely installed by mounting bases 16 provided on a horizontally installed frame 13 . Although the predetermined gradient in this case is about 1/10 (10/100) in this embodiment, it may be a gradient of 3/100 to 30/100.

The mounting frame 16 is made of steel material, stainless steel material, or aluminum material, but it can also be made of domestic thinning material.

Uniform irrigation of crops is as important as the irradiation intensity of crops. In this embodiment, as described above, both the solar panel 14 and the light diffusion member 15 have a width (long side) of 1800 mm, a length (short side) in the flow direction of about 600 mm, and a width of 1/10 in the short side direction. All panels are installed so that they slope downwards toward the south. In addition, in the present embodiment, gaps 17, which are rainwater outlets, are provided between the solar panel 14 and the light diffusion member 15 and between the solar panels 14 and 14 in the north-south direction. It is constructed so that rainwater can be poured onto the crops under the panel through the gap 17. - 特許庁The length of the gap 17 is approximately 20 mm. As a result, the rainwater received by the solar panel 14 and the light diffusing member 15 falls on the crops at intervals of about 600 mm, so uniform watering is possible.

If the surface of the light diffusing member is flat, it is difficult for the received rainwater to fall evenly from the slanted tip portion, and the rainwater falls unevenly to either the left or the right. Since it is difficult to install such that the bottom part of the pipe is in a completely horizontal state, the rainwater flows down in one direction due to the influence of the wind and the hydrophilicity of the rainwater. However, as in this embodiment, by using the corrugated light diffusion member 15 and installing the flow direction along the inclined direction, the rainwater falling on the light diffusion member 15 and the rainwater flowing from the solar panel 14 can be evenly distributed to the bottom of the valley at a mountain pitch, the crops can be effectively watered from the water bottom end of each panel.

As shown in FIG. 2, in this embodiment, a plurality of solar panels 14 are arranged in rows along the east-west direction, and a plurality of solar panels 14 are arranged between the rows of solar panels 14. Light diffusion members 15 are arranged in one row. More specifically, in FIG. 2, the second, third, fifth, and sixth rows extending in the east-west direction are rows of solar panels 14, and the second row of solar panels 14 is in front of the second row. , and between the third and fifth rows, the light diffusing members 15 are arranged in the first and fourth rows in the east-west direction, respectively. The number of rows of the solar panels 14, the number of rows of the light diffusing members 15, and the mutual arrangement of the solar panels 14 and the light diffusing members 15 described above are merely examples, and are not limited to these. In short, it is sufficient that the rows of the light diffusion members 14 are arranged along the east-west direction between the rows of the solar panels 14 arranged along the east-west direction. In this embodiment, the planar area occupied by the plurality of solar panels 14 is 66%, while the planar area occupied by the plurality of light diffusion members 15 is 33%. If the light diffusing member 15 occupies 25% of the plane area, the direct sunlight with high light intensity is converted by the light diffusing member 15 into diffused light (scattered light, sky light) without shadows, and the direct sunlight Sufficient diffused light can be delivered to just below the solar panel 14 where light is not irradiated. Further, if the height (distance) from the light diffusion member 15 to the surface of the cultivated land 11 is reduced to, for example, 3 m, uniform and high illuminance can be obtained. The illuminance distribution and uniformity of the diffused light applied to the cultivated land 11 can be set according to the surface area, the installation interval, and the installation height of the light diffusion member 15, so it is desirable to appropriately determine them according to the crops 10 to be cultivated.

An important point in this embodiment is that each light diffusing member 15 is installed with a predetermined inclination downward toward one end of the solar sharing system (south direction in the northern hemisphere, north direction in the southern hemisphere). and that the shape is a corrugated plate shape and the direction of flow is along the direction of inclination. Accordingly, as will be described later, light is diffused not only downward but also laterally, so even when sunlight is incident at a low angle of incidence, the light diffusibility is greatly improved. As a result, light with a more uniform intensity distribution that is well diffused throughout the seasons of the year or throughout the hours of the day will illuminate the crops under the solar panel 14 with a more uniform intensity distribution. . Furthermore, since it is installed with a downward slope toward one end and the direction of flow is along the direction of the slope, rainwater will be evenly poured over the crops under the solar panel.

3 illustrates the structure of the light diffusing member 15 in this embodiment, and FIG. 4 shows the BB cross section of FIG.

As shown in these figures, the light diffusing member 15 of the present embodiment is a slate small wave-shaped frosted polycarbonate corrugated panel (width: 1800 mm, length in the flow direction: 600 mm, crest pitch: 63 mm, crest height: 18 mm), specifically Polykanami (registered trademark) of Sumitomo Bakelite Co., Ltd. is used. The surface or back surface of this polycarbonate corrugated panel may be embossed, or may be coated with a gainer paint having heat resistance, heat shielding properties and light diffusion properties.

FIG. 5 shows an example of how the light diffusing member 15 and the solar panel 14 are installed on the frame 13 in this embodiment.

As shown in FIG. 5, in this example, a solar panel 14 and a light diffusing member 15 are installed on a frame 13 horizontally supported by a column 12 by means of mounting bases 16, respectively. In that case, by varying the height of the mount base 16, the solar panel 14 and the light diffusion member 15 are installed so as to be inclined downward at a gradient of, for example, about 1/10 toward the south.

FIG. 6 shows another example of the installation form of the light diffusion member 15 and the solar panel 14 on the frame 13 in this embodiment.

As shown in FIG. 6, in this example, a solar panel 14 and a light diffusing member are mounted on a frame 13' which is tilted and supported by a column 12' so as to descend at a gradient of, for example, about 1/10 toward the south direction. 15 are each mounted by a mounting cradle 16' of the same height.

As explained in detail above, according to the present embodiment, since the light diffusing member 15 constitutes the entire lighting part, the direct light spreads from 60 degrees to 100 degrees, and even the crops immediately below the solar panel 14 can receive the same light. Diffused light is emitted from all directions, and a stable crop harvest can be expected. In particular, since the light diffusing member 15 has a corrugated plate shape, light is diffused not only downward but also laterally at a wider angle. significantly improved. As a result, light with a more uniform intensity distribution that is well diffused throughout the seasons of the year or throughout the hours of the day will illuminate the crops under the solar panel 14 with a more uniform intensity distribution. . Furthermore, the solar panel 14 and the light diffusing member 15 are installed inclined downward toward the direction of one end, and the flow direction of the corrugated plate shape of the light diffusing member 15 is along the direction of the inclination, and the gap 17 is provided, rainwater is uniformly poured over the crops under the solar panel 14 and the light diffusing member 15 . In this way, by constructing all the lighting parts with the light diffusing light member 15, the diffused light can be taken in directly under the solar panel 14, and uniform watering can be surely performed, so that the harvest of the farmer increases, Power generation companies can also increase the installation ratio and improve investment efficiency. As a result, it is expected that the solar sharing business will be reviewed, and the added value of fallow land will increase, leading to an increase in adoption. If the fallow land is revived, weirs, embankments, and irrigation canals for small and medium-sized rivers will be constructed, which will help prevent disasters caused by torrential rains. The present invention aims to achieve carbon neutrality and improve Japan's energy and food self-sufficiency rates. If you aim to sell electricity like a conventional power generation business, the business will not take root in the region. By aiming for consumption by farmers and local communities, the profits will be returned to the local communities for the first time. This electricity is used not only for household use, but also for local government facilities, such as the electrification of automobiles and agricultural machinery, and the heating of greenhouses, whose prices are soaring. This will require infrastructure such as large-scale storage batteries and electric stations, and building a regional consumption structure will be a challenge. As a result, the value of arable land in the region will increase, people will gather, and new businesses and employment will be created. In this way, it is hoped that the present invention will be disseminated as a model for regional revitalization and, for example, utilized as a concrete means of ensuring that no one is left behind even in areas without power lines.

In addition, in this embodiment, the solar panel 14 and the light diffusion member 15 are installed so as to be inclined downward toward the south direction in the northern hemisphere, which is the most efficient. However, depending on the location conditions, it may be installed facing east or west, or in the middle of each direction, although efficiency is reduced.

FIG. 7 schematically shows a cross-sectional configuration of a solar sharing system according to a second embodiment of the invention, and FIG. 8 schematically shows a planar configuration of the solar sharing system according to this embodiment. Note that FIG. 7 shows a CC section of FIG.

As shown in these figures, in the solar sharing system of this embodiment, a crop (cultivated product) 10 is planted above a cultivated field (or a cultivation tank in the case of hydroponics) 11 supported by a support 12. A plurality of solar panels 14' and a plurality of corrugated plate-shaped light diffusion members 15' for transmitting and diffusing sunlight are installed on the frame 13 by means of a mount 16. As shown in FIG. A plurality of light diffusion members 15' are provided between the plurality of solar panels 14'. By providing the light diffusing member 15' between the solar panels 14' in this way, the direct light is diffused, the direct light is prevented from irradiating only a part of the crops, and the direct light is prevented from irradiating only a part of the crops. Uniform diffused light can be delivered. That is, it is possible to uniformly irradiate the crops under the solar panel 14' from all directions and grow the crops stably. As shown in FIG. 7, if the light diffusing member 15' were not present, the direct light would irradiate only part of the area. The diffused light from the adjacent light diffusing member 15' intersects with the diffused light from the adjacent light diffusing member 15' to illuminate right under the solar panel 14'. It is desirable that the light diffusing member 15' and the solar panel 14' have the same shape and the same size, and that they are attached to the mounting frame 16 in the same manner.

In the first embodiment, a plurality of solar panels 14 are arranged in rows along the east-west direction, and a plurality of light diffusion members 15 are arranged between the rows of solar panels 14. In the present embodiment (second embodiment), the plurality of solar panels 14' are arranged in one row along the north-south direction, whereas they are arranged in one row along the north-south direction. Between the rows of solar panels 14', a plurality of light diffusion members 15' are arranged in one row along the north-south direction. More specifically, in FIG. 8, the second and fourth rows extending in the north-south direction are rows of solar panels 14', and between the rows of solar panels 14', light diffusing members 15' extend in the north-south direction. are sandwiched between the first and third rows of the . Although the light diffusing member 15' and the solar panel 14' in this embodiment have different shapes and different dimensions, they are configured to be attached to the mounting frame 16 by the same method.

In this embodiment, each solar panel 14' is a rectangular flat panel in which silicon-based solar cells or perovskite-based solar cells are provided on a metal substrate such as steel or stainless steel or a resin substrate. Its dimensions, which are merely an example, are approximately 1800 mm in width (long side) and approximately 600 mm in length (short side). The width (long side) can be appropriately selected within the range of about 900 mm to about 2000 mm, and the length (short side) can be selected within the range of about 500 mm to about 1000 mm. As a modification, the width (short side) may be approximately 600 mm and the length (long side) may be approximately 1800 mm. In that case, the width (short side) can be selected appropriately within the range of about 500 mm to about 1000 mm, and the length (long side) can be selected within the range of about 900 mm to about 2000 mm.

Each light diffusion member 15' has a square corrugated plate shape. By using the corrugated light diffusing member 15', the surface area is increased from about 1.2 times to about 1.5 times. It will be possible to efficiently diffuse and irradiate the sunlight of time. Also, the light diffusing member 15' must be inexpensive, tough, weather resistant, and rainproof. Furthermore, it is preferable that the transmittance is about 50% to 80% and the diffusion angle is about 60 degrees to 100 degrees, so that the crops immediately below the solar panel 14' can be irradiated with uniform diffused light from the north, south, east and west. As a result, even tall crops can be cultivated stably. Therefore, as the light diffusing member 15', a material that is easy to process, has a corrugated plate shape, and transmits and diffuses light is selected from materials that have been used as a roofing material. The corrugated plate shape is generally a folded plate shape, a circular wave shape, or a rectangular wave shape. As a material for transmitting and diffusing light, a polycarbonate material is desirable, but an FRP material may also be used. In addition, it is desirable to use a round-wave type commercial product that is inexpensive, has good weather protection, and is easy to install. Of course, the transmittance and diffusion angle of the light diffusing member 15' are selected in consideration of the installation height, the installation interval, the height of the crops, and the required illuminance. In this embodiment, the light diffusing member 15' is composed of a square corrugated polycarbonate panel, and its dimensions are merely an example, but the width and length are about 600 mm, and the peak pitch is about 63 mm. , and the peak height is about 18 mm. Specifically, although this is merely an example, polycarbonate corrugated panels, polycarbonate hollow panels (e.g., Polykanami (registered trademark), Polykatwin (registered trademark), Twincarbo (registered trademark), Paircarbo (registered trademark)), etc. light diffusion I am using a panel. Frost type and embossed finish improve diffusion. The width and length can be appropriately selected within the range of approximately 500 mm to approximately 1000 mm, and the pitch of the peaks can be selected within the range of approximately 30 mm to approximately 200 mm.

The plurality of solar panels 14 ′ and the plurality of light diffusion members 15 ′ have their length directions (flow direction in the case of corrugated plate shape) in the north-south direction, and in the south direction (south direction in the northern hemisphere, in the southern hemisphere It is installed so as to incline downward with a predetermined gradient toward the north direction). In this embodiment, a plurality of solar panels 14' and a plurality of light diffusing members 15' are obliquely installed by mounting bases 16 provided on a horizontally installed frame 13. As shown in FIG. Although the predetermined gradient in this case is about 1/10 (10/100) in this embodiment, it may be a gradient of 3/100 to 30/100.

The mounting frame 16 is made of steel material, stainless steel material, or aluminum material, but it can also be made of domestic thinning material.

Uniform irrigation of crops is as important as the irradiation intensity of crops. In the present embodiment, as described above, the light diffusing member 15' has a square shape, and has a water gradient of about 1/10 in the direction of the tip side in the flow direction, and all the panels are inclined downward in the south direction. It's set up like this. In addition, in this embodiment, gaps 17 are provided to drain rainwater between the light diffusing members 15' and between the solar panels 14' and 14' in the north-south direction. Through this gap 17, rainwater is poured onto the crops under the panel. The length of the gap 17 is approximately 20 mm. As a result, the rainwater received by the solar panel 14' and the light diffusing member 15' falls on the crops at intervals of about 600 mm, so uniform watering is possible.

If the surface of the light diffusing member is flat, it is difficult for the received rainwater to fall evenly from the slanted tip portion, and the rainwater falls unevenly to either the left or the right. Since it is difficult to install such that the bottom part of the pipe is in a completely horizontal state, the rainwater flows down in one direction due to the influence of the wind and the hydrophilicity of the rainwater. However, as in this embodiment, by using the corrugated light diffusion member 15' and installing the flow direction along the inclined direction, rainwater falling on the light diffusion member 15' and the solar panel 14' Since the rainwater that has flowed in can be evenly distributed to the bottom of the valley at a mountain pitch, it is possible to effectively water the crops from the water bottom end of each panel.

The number of rows of the solar panels 14', the number of rows of the light diffusing members 15', and the mutual arrangement of the solar panels 14' and the light diffusing members 15' are merely examples, and the present invention is not limited to these. The point is that the rows of the light diffusing members 14' are arranged along the north-south direction between the rows of the solar panels 14' arranged along the north-south direction. In this embodiment, the planar area occupied by the plurality of solar panels 14' is 66%, while the planar area occupied by the plurality of light diffusion members 15' is 33%. If the light diffusing member 15' occupies 25% of the planar area, the direct sunlight with high light intensity is converted into shadowless diffused light (scattered light, sky light) by the light diffusing member 15'. Sufficient diffused light can be delivered to just below the solar panel 14' where direct sunlight is not irradiated. Further, if the height (distance) from the light diffusing member 15' to the surface of the cultivated land 11 is reduced to, for example, 3 m, uniform and high illuminance can be obtained. The illuminance distribution and uniformity of the diffused light applied to the cultivated land 11 can be set according to the surface area, installation interval, and installation height of the light diffusing member 15'.

An important point in this embodiment is that each light diffusing member 15' is installed with a predetermined slope downward toward one end of the solar sharing system (southward in the northern hemisphere, northward in the southern hemisphere). and that the shape is a corrugated plate shape and the direction of flow is along the direction of inclination. Accordingly, as will be described later, light is diffused not only downward but also laterally, so even when sunlight is incident at a low angle of incidence, the light diffusibility is greatly improved. As a result, light with a more uniform intensity distribution that is well diffused throughout the seasons of the year or throughout the hours of the day illuminates the crops under the solar panel 14' with a more uniform intensity distribution. Become. Furthermore, since it is installed with a downward slope toward one end and the direction of flow is along the direction of the slope, rainwater will be evenly poured over the crops under the solar panel.

Since the configuration of the light diffusion member 15' of this embodiment is the same as that of the light diffusion member 15 of the first embodiment, description thereof will be omitted.

The manner in which the light diffusing member 15' and the solar panel 14' are installed on the frame 13 in the present embodiment is the same as in the first embodiment, so the description thereof is omitted.

As explained in detail above, according to the present embodiment, the direct light spreads from 60 degrees to 100 degrees by constructing the lighting part entirely with the light diffusion member 15', and the direct light reaches the crops directly under the solar panel 14'. Uniform diffused light is emitted from all directions, and a stable harvest of crops can be expected. In particular, since the light diffusing member 15' has a corrugated plate shape, light is diffused not only downward but also laterally at a wider angle. significantly improved. As a result, light with a more uniform intensity distribution that is well diffused throughout the seasons of the year or throughout the hours of the day illuminates the crops under the solar panel 14' with a more uniform intensity distribution. Become. Furthermore, the solar panel 14' and the light diffusing member 15' are inclined downward toward one end, and the corrugated plate-shaped flow direction of the light diffusing member 15' extends along the direction of the inclination. Since the gap 17 is provided, the rainwater is uniformly poured onto the crops under the solar panel 14' and the light diffusing member 15'. In this way, by constructing all the light-receiving parts with the light-diffusing light member 15', the diffused light can be taken in directly under the solar panel 14', and uniform watering can be ensured, so that the farmer's harvest can be improved. As a result, power generation companies can also increase the installation ratio and improve investment efficiency. As a result, it is expected that the solar sharing business will be reviewed, and the added value of fallow land will increase, leading to an increase in adoption. If the fallow land is revived, weirs, embankments, and irrigation canals for small and medium-sized rivers will be constructed, which will help prevent disasters caused by torrential rains. The present invention aims to achieve carbon neutrality and improve Japan's energy and food self-sufficiency rates. If you aim to sell electricity like a conventional power generation business, the business will not take root in the region. By aiming for consumption by farmers and local communities, the profits will be returned to the local communities for the first time. This electricity is used not only for household use, but also for local government facilities, such as the electrification of automobiles and agricultural machinery, and the heating of greenhouses, whose prices are soaring. This will require infrastructure such as large-scale storage batteries and electric stations, and building a regional consumption structure will be a challenge. As a result, the value of arable land in the region will increase, people will gather, and new businesses and employment will be created. In this way, it is hoped that the present invention will be disseminated as a model for regional revitalization and, for example, utilized as a concrete means of ensuring that no one is left behind even in areas without power lines.

In this embodiment, the solar panel 14' and the light diffusing member 15' are installed with a downward inclination toward the south direction in the northern hemisphere, which is the most efficient. However, depending on the location conditions, it may be installed facing east or west, or in the middle of each direction, although efficiency is reduced.

FIG. 9 schematically shows a cross-sectional configuration of a solar sharing system according to a third embodiment of the invention, and FIG. 10 schematically shows a planar configuration of the solar sharing system according to this embodiment. Note that FIG. 9 shows a DD cross section of FIG.

As shown in these figures, in the solar sharing system of the present embodiment, a pillar (not shown ) is installed, and this frame (not shown) has a plurality of corrugated solar panels 14″ and a plurality of corrugated light diffusion members 15 for transmitting and diffusing sunlight. ″ are installed by mounting brackets (not shown). A plurality of light diffusion members 15'' are provided between the plurality of solar panels 14''. By providing the light diffusing member 15'' between the solar panels 14'' in this way, the direct light is diffused to prevent the direct light from irradiating only a part of the crops. Uniform diffused light can be delivered, that is, the crops under the solar panel 14″ can be uniformly irradiated from all directions to grow the crops stably. If the light diffusing member 15″ were not present, the direct light would be radiated only partially. '', the diffused light from the adjacent light diffusing member 15'' intersects and is irradiated. It is desirable that the light diffusion member 15'' and the solar panel 14'' have the same shape and the same size, and are preferably configured to be attached to the mounting frame in the same manner.

In the first embodiment, a plurality of solar panels 14 are arranged in rows along the east-west direction, and a plurality of light diffusion members 15 are arranged between the rows of solar panels 14. In the present embodiment (third embodiment), the plurality of solar panels 14″ are arranged in two rows along the north-south direction. Between two rows of solar panels 14″, a plurality of light diffusing members 15″ are arranged in one row along the north-south direction. More specifically, In FIG. 10, the 1st, 2nd, 4th, 5th, 7th, 8th, 10th, 11th, 13th and 14th columns extending in the north-south direction are solar cells. The panels 14″ are arranged in rows, and the light diffusing members 15″ in the third, sixth, ninth, and twelfth rows in the north-south direction are sandwiched between the rows of the solar panels 14″. ing. Moreover, in this embodiment, the solar panel 14'' also has a corrugated plate shape like the light diffusion member 15''. It is desirable that the light diffusing member 15'' and the solar panel 14'' in this embodiment have the same shape and the same size, and that they are attached to the mounting frame in the same manner.

In this embodiment, each solar panel 14″ is a rectangular flat panel in which silicon-based solar cells or perovskite-based solar cells are provided on a metal substrate such as steel or stainless steel or a resin substrate. Although the dimensions are merely an example, the length (long side) in the flow direction is about 1800 mm, the width (short side) is about 600 mm, the pitch is about 63 mm, and the height is about 18 mm. (Long side) can be appropriately selected from a range of about 900 mm to about 2000 mm, and the width (short side) can be appropriately selected from a range of about 500 mm to about 1000 mm. In some cases, the length (longer side) is about 1800 mm, in which case the length (shorter side) can be selected within the range of about 500 mm to about 1000 mm, and the width (longer side) can be appropriately selected within the range of about 900 mm to about 2000 mm.

Each light diffusing member 15″ has a rectangular corrugated plate shape. By using the corrugated light diffusing member 15″, the surface area increases from about 1.2 times to about 1.5 times. Therefore, it is possible to efficiently diffuse and irradiate the sky light especially when it is cloudy or rainy and the sunlight when the altitude of the sun is low. Further, the light diffusing member 15'' must be inexpensive, strong, excellent in rain protection, and resistant to storms. Further, it has a transmittance of about 50% to 80% and a diffusion angle of about 60 degrees to 100 degrees. This makes it possible to irradiate the crops right under the solar panel 14″ with uniform diffused light from north, south, east and west, and as a result, even tall crops can be cultivated stably. . Therefore, as the light diffusing member 15″, a material that is easy to process, has a corrugated plate shape, and is capable of transmitting and diffusing light is selected from materials that have been used as roofing materials and have a track record. As a material for transmitting and diffusing light, a polycarbonate material is desirable, but an FRP material may also be used. It is desirable to use a commercially available product with a circular wave shape that is easy to install and is easy to install. It is selected in consideration of the illuminance to be applied. In this embodiment, the light diffusing member 15″ is composed of a rectangular corrugated polycarbonate panel, and its dimensions are merely an example, but the length (long side) in the flow direction is about 1800 mm, The width (short side) is about 600 mm, the peak pitch is about 63 mm, and the peak height is about 18 mm. The peak pitch can be appropriately selected in the range of about 30 mm to about 200 mm.Specifically, although it is only an example, polycarbonate corrugated panel, polycarbonate hollow panel (for example, Polykanami (registered trademark), Polykatwin (registered trademark) , TWINCARBO (registered trademark), PAIRCARBO (registered trademark), etc. are used.The use of a frosted type or embossed finish further improves diffusion.As a modification, the length in the flow direction (short side ) is about 600 mm and the width (long side) is about 1800 mm, in which case the length (short side) is about 500 mm to about 1000 mm and the width (long side) is about 900 mm to about 2000 mm. It is selectable.

The plurality of solar panels 14″ and the plurality of light diffusing members 15″ have their flow directions in the north-south direction and downward at a predetermined gradient toward the south direction (south direction in the northern hemisphere, north direction in the southern hemisphere). installed so as to incline to In this embodiment, a plurality of solar panels 14'' and a plurality of light diffusing members 15'' are obliquely installed by mounting frames provided on a horizontally installed frame. Although the predetermined gradient in this case is about 1/10 (10/100) in this embodiment, it may be a gradient of 3/100 to 30/100.

The mounting frame is made of steel material, stainless steel material, or aluminum material, but it can also be made of domestically produced thinning material.

Uniform irrigation of crops is as important as the irradiation intensity of crops. In this embodiment, the solar panel 14″ and the light diffusing member 15″ have a water gradient of about 1/10 in the direction of the tip side in the flow direction, and are installed so that all the panels are inclined downward in the south direction. there is In this embodiment, as in the first and second embodiments, gaps 17 are provided between the solar panels 14'' and between the light diffusion members 15''. Furthermore, in the present embodiment, through holes 18 serving as rainwater outlets are provided at predetermined intervals in the flow direction at the bottoms of the valleys in the flow direction of the solar panel 14'' and the light diffusion member 15''. This predetermined interval between the through-holes 18 is preferably about 400 mm to about 1000 mm when the length of the solar panel 14'' or the light diffusion member 15'' in the flow direction exceeds 1000 mm. Rainwater received by the solar panel 14'' and the light diffusing member 15'' is poured through the gap 17 and the through-hole 18 to the crops under the panel, so uniform watering is possible.

If the surface of the solar panel or the light diffusing member is flat, it is difficult to make the received rainwater fall evenly from the slanted tip portion, and the rainwater falls unevenly to the left or right. Since it is difficult to install such that the bottom part of the pipe is in a completely horizontal state, the rainwater flows down in one direction due to the influence of the wind and the hydrophilicity of the rainwater. However, as in this embodiment, by using the corrugated solar panel 14'' and the light diffusion member 15'' and installing the flow direction along the inclined direction, the solar panel 14'' and the light diffusion member 15'' ″ can be evenly distributed to the bottom of the valley at a mountain pitch, so that crops can be watered effectively through the gaps 17 and the through holes 18 of the panel.

The number of rows of the solar panels 14'', the number of rows of the light diffusing members 15'', and the mutual arrangement of the solar panels 14'' and the light diffusing members 15'' are merely examples, and are not limited to these. The point is that the rows of the light diffusing members 14″ are arranged along the north-south direction between the rows of the solar panels 14″ arranged along the north-south direction. In this embodiment, the planar area occupied by the plurality of solar panels 14'' is 66%, while the planar area occupied by the plurality of light diffusion members 15'' is 33%. If the light diffusion member 15″ occupies 25% of the planar area, the direct sunlight with high light intensity is converted into shadowless diffused light (scattered light, sky light) by the light diffusion member 15″. Sufficient diffused light can be delivered to just below the solar panel 14″, which is not exposed to direct sunlight. Further, if the height (distance) from the light diffusion member 15″ to the surface of the cultivated land 11 is reduced to, for example, 3 m. , uniform and high illuminance can be obtained. The illuminance distribution and uniformity of the diffused light applied to the cultivated land 11 can be set according to the surface area, installation interval, and installation height of the light diffusing members 15″.

An important point in this embodiment is that both the solar panel 14'' and the light diffusing member 15'' are lowered at a predetermined gradient toward one end of the solar sharing system (southward in the northern hemisphere, northward in the southern hemisphere). , and the shape is a corrugated plate, and the direction of flow is along the direction of the inclination. Accordingly, as will be described later, light is diffused not only downward but also laterally, so even when sunlight is incident at a low angle of incidence, the light diffusibility is greatly improved. As a result, the crops under the solar panels 14″ are illuminated with a more uniform intensity distribution of light that is well diffused throughout the seasons of the year or throughout the hours of the day. In addition, since it is installed with a downward slope toward one end and the direction of flow is along the direction of the slope, rainwater is evenly poured over the crops under the solar panel.

Since the structure of the light diffusion member 15'' of this embodiment is the same as that of the light diffusion member 15 of the first embodiment, the description thereof is omitted.

A perovskite film 14b'' is laminated on a certain substrate panel 14a''. A perovskite solar cell can be expected to have high efficiency and high durability, and can be manufactured by forming a film by a printing method or the like. It is very useful when applied to the solar panel 14″ of this embodiment.

The manner in which the light diffusing member 15'' and the solar panel 14'' are installed on the frame in the present embodiment is the same as in the first embodiment, so the description thereof is omitted.

As explained in detail above, according to the present embodiment, since the light diffusing member 15'' constitutes the entire lighting part, the direct light spreads from 60 degrees to 100 degrees, and even the crops directly under the solar panel 14''. Uniform diffused light is emitted from all directions, and a stable harvest of crops can be expected. In particular, since the light diffusing member 15″ has a corrugated plate shape, the light is diffused not only downward but also laterally at a wider angle. As a result, the light, which is well diffused and has a more uniform intensity distribution throughout the seasons of the year or time of day, provides a more even intensity of illumination to the crops under the solar panel 14″. It will be irradiated with distribution. Furthermore, the solar panel 14″ and the light diffusion member 15″ are installed inclined downward toward one end, and the flow direction of the corrugated plate shape is along the direction of the inclination, and the gap 17 and the through hole Due to the holes 18, rainwater is evenly poured onto the crops under the solar panel 14'' and the light diffusing member 15''. In this way, by constructing all the lighting parts with the corrugated light diffusion light member 15 ″, diffused light can be taken in directly under the solar panel 14 ″ and uniform watering can be reliably performed. It is possible to improve investment efficiency by increasing the harvest of power generation companies and increasing the installation ratio of power generation companies. As a result, it is expected that the solar sharing business will be reviewed, and the added value of fallow land will increase, leading to an increase in adoption. If the fallow land is revived, weirs, embankments, and irrigation canals for small and medium-sized rivers will be constructed, which will help prevent disasters caused by torrential rains. The present invention aims to achieve carbon neutrality and improve Japan's energy and food self-sufficiency rates. If you aim to sell electricity like a conventional power generation business, the business will not take root in the region. By aiming for consumption by farmers and local communities, the profits will be returned to the local communities for the first time. This electricity is used not only for household use, but also for local government facilities, such as the electrification of automobiles and agricultural machinery, and the heating of greenhouses, whose prices are soaring. This will require infrastructure such as large-scale storage batteries and electric stations, and building a regional consumption structure will be a challenge. As a result, the value of arable land in the region will increase, people will gather, and new businesses and employment will be created. In this way, it is hoped that the present invention will be disseminated as a model for regional revitalization and, for example, utilized as a concrete means of ensuring that no one is left behind even in areas without power lines.

In this embodiment, the solar panel 14'' and the light diffusing member 15'' are installed with a downward inclination toward the south direction in the northern hemisphere, which is the most efficient. However, depending on the location conditions, it may be installed facing east or west, or in the middle of each direction, although efficiency is reduced.

Uniform diffused light can be delivered, that is, the crops under the solar panel 14″ can be uniformly irradiated from all directions to grow the crops stably. If the light diffusing member 15″ were not present, the direct light would be radiated only partially. '', the diffused light from the adjacent light diffusing member 15'' intersects and is irradiated.

In this embodiment (fourth embodiment), a plurality of solar panels 14″ are arranged in a row along the north-south direction, and between each row of these solar panels 14″, A plurality of light diffusing members 15″ are arranged in a row along the north-south direction. Since it is the same as the case of the embodiment, the explanation is omitted.

These LED light emitting units 21 are driven by power generated by the solar panel 14″ or by power from a battery (not shown) that stores the power, and are used as auxiliary lighting sources that do not rely on external power.

An important point in this embodiment is that both the solar panel 14'' and the light diffusing member 15'' are lowered at a predetermined gradient toward one end of the solar sharing system (southward in the northern hemisphere, northward in the southern hemisphere). , and the shape is a corrugated plate, and the direction of flow is along the direction of the inclination. Accordingly, as will be described later, light is diffused not only downward but also laterally, so even when sunlight is incident at a low angle of incidence, the light diffusibility is greatly improved.

As in the present invention, the light diffusing effect was measured when light was diffused from a corrugated light diffusing member. A skylight (1 m x 15 m) at a height of 12.5 m from the floor is wired glass. Directly below ( 0 m), and the illuminance at positions 1 m, 2 m, 3 m, 4 m, 5 m, 6 m, 7 m, and 8 m away from directly below in the direction orthogonal to the flow direction of the corrugated plate. As an illuminance meter, TR-74Ui manufactured by T&D Co., Ltd. was used. The illuminance measurement was performed in late April under sunny and sometimes slightly cloudy weather. The transmittance of glass is 90%, the transmittance of glass and polycarbonate (registered trademark) is 55.8%, the transmittance of glass and polycarbonate (registered trademark) is 72%, the transmittance of glass and polycarbonate (registered trademark) and The transmittance with the laminated panel of Polykanami (registered trademark) is 44.6%. Table 1 shows the measurement results of the illuminance at each position. The external illuminance at the time of measurement of POLYKATWIN (registered trademark) and POLYKANAMI (registered trademark) was unmeasurable due to drastic weather changes.

From Table 1, polycarbonate twin (registered trademark) and laminated panels of polycarbonate twin (registered trademark) and polycarbonate (registered trademark) have lower transmittance than polycarbonate (registered trademark). ) has the second highest transmittance after glass, but it has a high illuminance distribution even at a position far away from directly below, and it is said that the diffusivity is very excellent compared to Polykatwin (registered trademark).
