Description

We will build a system to protect and utilize the natural environment, reduce wind damage, comfortably protect plants that reduce CO2, and build an environmentally friendly society.

Green houses and plastic greenhouses are widely used in agriculture, but they can be blown away or destroyed by strong winds or typhoons, and 80% of the damage is caused by wind. The power generation efficiency of solar power is at most 20%. The other 80% of the energy is not used and escapes into space, which is a waste. The purpose is to effectively utilize natural energy.

Wind damage accounts for 80% of the damage to vinyl greenhouses, which are a typical type of greenhouse and are widely used.
The objective is to preserve the environment by providing air conditioning and appropriate temperature for the plants grown in the greenhouse, and solar cells are used to generate natural energy, but they are used separately on land separate from the greenhouse. As a result, wind damage continues, and the installation of solar cells is limited because the slope is gentle and the area of land occupied is large, making it difficult to secure land for installation.
It is desirable to eliminate wind damage, reduce the installation area of solar cells, and directly face sunlight. Commercial power supply can be reduced, and independent energy can be used in places without electricity. Since the solar energy used for solar power generation is at most 20% or less, it is desirable to utilize the heat loss of the remaining 80%. In addition, solar heat and wind can also be used.

Solar panels are installed around or in part of a greenhouse or vinyl greenhouse so that they stand in front of the wind to act as a windbreak, and the direction of the wind is changed so that the wind flows along the panels. By concentrating the amount of air and collecting the air volume, the speed is changed to V2' (Vpt), making it a strong wind force and the wind power Pa = ρVpt ² /2, which is faster than wind power (WM) power generation using the natural wind speed V ₁ (Vp). It creates the effect of killing two birds with one stone by generating a large amount of energy by multiplying the speed. Therefore, it is possible to not only protect greenhouses or greenhouses by using the wind, which was previously disliked as a source of wind damage, but also to efficiently run windmills and obtain electricity, which can kill three birds with one stone, including solar power generation. will be able to produce. In other words, the present invention can overcome harm and achieve benefit, and is a technology that is useful for effective utilization of natural energy and sunlight, as well as CO ₂ reduction through plants. Additionally, a water heater using solar heat is installed on the windbreak wall, making it possible to maintain a comfortable temperature in the greenhouse or plastic greenhouse.
Solar cells generate heat, so rather than simply dissipating this heat, it is used to heat water and warm the room. Furthermore, by integrating the solar cell walls and the greenhouse, it becomes a more solid structure and a more efficient greenhouse that does not allow heat to escape.
Growing plants, including greenhouses or plastic greenhouses, to make food, and by absorbing carbon dioxide ( _CO2 ) to create glucose, fix nitrogen, and produce effective ingredients, it is even more economical. can be raised.

Therefore, you can not only protect your greenhouse or greenhouse by making use of the wind, which was previously disliked as a form of wind damage, but also use the wind to efficiently rotate windmills and obtain electricity, which can kill three birds with one stone, including solar power generation. Be able to produce effects.

In other words, the present invention can overcome harm and achieve benefit, and is a technology useful for effective use of natural energy and reduction _{of CO2} .
Green houses or plastic greenhouses are used to grow plants and produce food, so they can absorb carbon _dioxide gas to produce glucose, fix nitrogen, and produce effective ingredients, making them even more economical. can be raised.

In addition to selling electricity generated, solar heat can be used to control the temperature, humidity, CO ₂ , nitrogen, lighting, etc. of greenhouses and greenhouses, allowing for control, adjustment, and power generation tailored to plants. By making it possible to adjust the economic use of energy, its value will further increase, and the effect of killing two birds with one stone can be achieved.

Instead of setting up a separate location for solar cells and lining up solar cells on a small piece of land, you can make effective use of the land by using it as a windbreak and integrating it with the greenhouse.

By integrating the heat generated by solar cells and the heat generated by a solar water heater, the heat generated here can be effectively utilized within the greenhouse without being dissipated into the air.

The present invention will be explained with reference to the drawings.

FIG. 1 shows a perspective view of a typical greenhouse. A vinyl house is made of a frame made of pipes covered with vinyl, and is lightweight and easily blown away by the wind. Especially when it is hit by a crosswind, it is subject to a large wind pressure load and can be blown away relatively easily. Since the wind pressure load W is W=CPaS, the larger the cross-sectional area Sav, the greater the wind pressure load and the damage caused by being blown away.

Figure 2 shows a case where a solar panel is installed approximately on the south side of a greenhouse and placed for wind protection and sunlight reception.
Japan is in the Northern Hemisphere, so the solar cells face south, and the sun rises upwards, so they face upwards.If you stand them up vertically, they have the effect of being a wall, but if you take into account the light received by the solar system, the efficiency will be poor, and you can It is desirable to install the solar panel so that it is perpendicular to the sunlight. By making the light-receiving surface of the solar panel as wide as possible and allowing the wind blowing from the side to escape upward, the wind pressure load received by the solar panel is reduced to Pv, and the wind pressure induced upward becomes Pp.
As will be described later, the induced wind Pp has a narrowed cross section S, increases the wind speed V, and becomes vpt, strongly rotating the wind turbine installed above. Wind power is generated by generating electricity with the generator EG attached to the shaft of the wind turbine, and it also generates wind power with solar panels, which not only eliminates wind damage but also makes effective use of wind power, and can be used simply as a storm wall. Instead, the force P=1/2ρVpt2 that guides the wind upward and turns the windmill can produce a larger force. In the figure, the elevation angle of the solar panel is the same as the original one. From an economic point of view, the benefits of generating electricity from solar cells and the storm effect that protects the house are significant. Although it varies depending on conditions, etc., it is desirable that it be larger than the vertical section Sw of the greenhouse.

Figure 2(b) shows a case where a green house or vinyl house has its gable side on the south side. The gable of a house is generally shorter than the side, so two or three houses are usually built. This varies depending on the size and shape of the field and land, but the gable side of a typical greenhouse is 6 to 8 m, so Figure 2(a) shows two greenhouses, and Figure 2(b) shows three greenhouses. Indicates the case of an individual building. The idea of the solar power generation panel is the same as in Figure 1.

In Figure 3, sunlight is shown by a thick white arrow ⇒, and wind direction is shown by a black arrow →. On the left side is the windbreak panel.In the summer, sunlight shines directly from above during the daytime, but in the winter, as it travels south, it is directed downwards. Therefore, considering the annual average value, the inclination and size of the solar panel WSSB will vary depending on the installation location, snow and weather, and the type of plants grown in the greenhouse VH. are slightly different. As a model, the left side faces south, and the solar panels are installed approximately facing south. Depending on the location, it may not be possible to completely face south, and the installation conditions will differ depending on whether the side or surface faces south.
If the wind blows from the side and the wind speed is v, the wind pressure p is expressed as P = (1/2) ρv2, and this vector is divided into a component perpendicular to the solar panel and a component parallel to the solar panel. The force acting on is a vector Psinθ parallel to the Pcosθ panel.
When the panel is laid down, the angle of elevation θ increases, and in order to maintain the height h, the solar panel must be made longer.
If it is set vertically, the sunlight receiving surface will be small, the wind will be received vertically, the wind pressure will be large, the wind will escape in three directions, and wind power generation will not operate effectively.
Even in Japan, the angle of elevation of the sun differs depending on the latitude and in summer and winter, but if it is installed at the most effective angle of inclination of 40 to 60 degrees, it will be suitable for sunlight and will allow wind to escape. The solar cell panel is also suitable for wind power generation and as a windbreak for greenhouses VH. In order to prevent the installation of general solar cells from creating shadows, the structure is such that θ is increased and laid down.
The solar panel may be semi-transparent, or it may have a structure in which solar cells are roughly stretched over a transparent panel that allows sunlight to pass through, allowing some sunlight to pass through and providing sufficient sunlight for the greenhouse. It is best to use a structure that provides the following.
The closer the distance G between the solar cell WSSB and the greenhouse, the more effective the windbreak will be, but it will also be affected by the shadow of the solar cell panel, so even if the installation location is closer to the equatorial plane, light will still enter from above. It's good, but the farther north you go, the more oblique the incidence is, so you'll need to move farther away. However, if a solar cell panel WSSB with transparent electrodes or semi-transparent electrodes is used, there is no need to be particularly concerned about the installation separation distance G. There is also a method of providing it at the top as described below.
In addition, solar cells mounted on tempered glass or polycarbonate plates allow light to pass through, so they can be used directly on the top or side surfaces.
The structure and foundation that supports the solar panel WSSB should be designed as appropriate for the land. A windbreak wall WSW is installed on the north side. As will be described later, a windbreak wall for the solar panel may also be used on the north side. To prevent it from being blown away by the wind, by placing a steel frame F such as an angle along the bottom and connecting it to the greenhouse or windbreak wall in the north, the foundation can be built only above without burying it in the field. Since there is a space below the solar panel, it is possible to house equipment such as battery B and a charging controller power conditioner, and in some cases, it is also possible to raise animals. To use the space inside the greenhouse as effectively as possible. Plastic greenhouses sometimes have a rectangular structure as shown by the dotted line, using transparent plates such as glass or polycarbonate.

Figure 4 shows the law that when wind blows from the side, the direction of the wind is changed upwards when it hits the solar panel WSSB, and the wind volume becomes a thin conductor, and the wind speed increases by the amount of compression. Sw1Vp-SW2Vpt
It shows the principle that SW1>SW2 and Vp<Vpt, and utilizes the principle that the wind that gathers above the panel becomes faster and can rotate the windmill installed here vigorously. Since the wind pressure becomes P∝Vpt2, a force equal to the square of the speed is obtained. This is where it differs from ordinary windmills.
A combination of solar cells will also be installed on the east, west, and north sides to avoid the influence of winds from the east SPE and west WPE.
The south side of the north windbreak wall can be used for solar cells, solar water heaters, etc., and the lower part can be used for machine rooms, hot water tanks, animal breeding, etc. in the same way as the south side.

Figure 5(a) shows a case where two or more vinyl houses VH are built, and although it may be handled individually, if several vinyl houses VH1H2-- are covered at once. shows.
Although it depends on the terrain, the further you move away from the windbreak solar cell WSSB, the wind will come in from around you and from above, making the windbreak effect weaker. It is also related to the size and height of the WSSB and windbreak wall.
FIG. 5(b) shows a case where windproof solar cell panels are installed in each greenhouse. In the case of a southerly wind, FIG. 5(b) is more advantageous, but in the case of a northerly wind, as will be described later, FIG. 5(a) is more advantageous in letting the invading wind escape.
In either case, conditions vary depending on the height of the windbreak wall, installation conditions, strength of the greenhouse, etc. In place of the north wall, a solar battery panel WSSB can be used even in the case of only one VH, as shown in the same figure.

FIG. 6 shows that the installation angle and size vary depending on the size of the land on which the solar panel is installed and which side is more important.
Standing solar panels vertically is advantageous in securing height, but the area that receives sunlight decreases and the power generation capacity decreases.
In addition, since the wind hits the area at almost right angles, it receives a large amount of wind pressure, so the structure must be strong, and it is difficult to utilize the wind through windmills. Furthermore, if the solar battery panel is laid down too much, the solar battery panel will become larger and the land occupation rate will increase accordingly, making it impossible to effectively use the solar panel as a greenhouse. Therefore, it is necessary to select solar panels, vinyl houses, greenhouses, or buildings depending on the size of the land, the purpose of use, etc.
The elevation angle is approximately 40 to 60 degrees, but in windy areas it may be better to lay it down even further.
As explained in Figure 4, the windbreak wall on the north side can be used for solar power generation, solar water heaters, machine rooms, animal breeding, etc.

FIG. 7(a) shows the solar cell panels installed on the east, west and south sides, viewed from the south side.
We have explained the solar panel WSSB in a rectangular form, but if you install one on the south side, that is fine, but if you install it on the east and west sides, the three sides are slanted, so there will be a gap, so please install it between these sides. Although it may be sealed with another material, there is also a method in which the solar cell panel WSSB is configured in a trapezoidal shape as shown by the dotted line and each side is combined.
Regarding the north side, solar cells, sunlight reflection, water heaters, and windbreak walls will be discussed later. If there is a mountain or forest behind you, use it.

In Fig. 7(b), instead of combining the south, east and west sides of a trapezoid as shown in Fig. 7(a), if the east and west walls are inclined, the corners may be covered with triangular panels.

Figure 8 shows an example of solar panels in the north, south, east, and west. In the case of east and west, the length may be long or short, so whether or not it is necessary to create a windbreak wall with solar panels depends on the installation conditions. . Since the sun is lower in the east-west direction, there is no need to incline as much, so this needs to be taken into account. The appearance will be the same in the case of integrated walls and roof, which will be described later.

In the case of FIGS. 8(a) and 8(b), the south-facing panel and the east-west panel are shown with different elevation angles (inclinations).
An example is shown in which the east and west panels are saved and not made large, and they are built almost vertically to cope with the rising and setting sun becoming lower. Figure (b-2) shows the windbreak wall viewed from above, and only the south side is sloped to allow sunlight and wind to escape.
The north wall may be constructed of steel, wood, banks, glass, plastic, metal, etc. It is desirable to make effective use of the north wall panel as in the previous example.

In FIG. 9, the wind that hits the windproof solar cell panel WSSB gathers at the tip and is guided upward into the sky, and the wind creates a swirl at the end. If the end of the greenhouse is too close to the greenhouse, part of the greenhouse may get caught up in the swirl and be destroyed, so it is better to separate it a little. The northern windbreak wall will be discussed later.

Figure 10 shows a case in which the panels are installed with a gap below to allow the wind to escape so as not to destroy the greenhouse due to the return wind generated by entering the inside of the solar cell panel due to the north wind.
At the edges of the panel, some of the air molecules are drawn by the wind and become thinner, and some of the air enters the thinner areas, creating swirls. It is necessary to move the greenhouse a little further away or tilt it so that it is not affected by this swirl.
Utilizing this swirling wind and the wind escaping to the sky or to the right, as described later, a propeller or windmill is used to create rotation, and a generator is attached to the rotating shaft to generate electricity, providing wind protection, solar power generation, The purpose is to take advantage of the natural phenomenon of wind power generation, which kills three birds with one stone. The north wall can also be used for solar cells, wind power generation, solar heat generation, sunlight reflection, solar water heating equipment, etc.
Most of the wind is blocked by the solar panels on the south side.
In the case of wind from the north, most of the north wind is blocked by the north wall, but some of it may enter along the slanted solar panels and bounce off the bottom, potentially destroying the greenhouse. The north side will also be discussed later.
Therefore, a gap is provided at the bottom to release the pressure of this wind.

By tilting the north wall to allow the wind to escape upwards as shown in FIG. 10(b), wind power generation can be performed while allowing the wind to escape in the same way as the south wall.

FIG. 11 shows the arrangement of windbreak walls and windbreak walls formed by solar cell panels (WSSB) when viewed from above, and it is also possible to arrange them in a polygonal shape such as a trapezoid or a triangle.
It is desirable to take appropriate measures depending on the size and number of greenhouses and the structure of the land.

FIGS. 11(a) and 11(b) show a trapezoidal structure with the east and west sides facing south as much as possible and installed so that a large amount of sunlight can be received. It may also be of an integral structure as described later.

Figures 12(a) and (b) show that by creating a gap and an auxiliary panel below the solar cell windbreak wall, north winds are guided to the outside, and on the other hand, south winds pass under the solar cells and enter. We show a method to prevent this.
To prevent this, an auxiliary shielding panel SW1 is installed in front of the gap with a space g2 to guide the south wind to the sky and prevent the south wind from directly invading. Even a portion of the wind that has entered the greenhouse is blocked by an internal shielding auxiliary panel SW2 so that it does not directly hit the greenhouse.
Even against northerly winds, the internal auxiliary panel SW2 guides the wind and prevents the wind from bouncing back. As shown in Figures (b) and (c), the windbreak wall panels installed on the north side can utilize sunlight and allow the north wind to escape to the top to rotate windmills, producing the same effect as using sunlight on the south side. Furthermore, the north wall has the advantage of being able to be used as described below, since there is no need to worry about creating shade behind it.
As in the case of Figure (c), when the windbreak wall and roof are integrated with vinyl sheets, glass plates, reinforced glass plates, or plastic plates and polycarbonate plates, there is no need to worry about collapse or destruction due to wind.

FIG. 13 is an explanatory diagram of a case where a windmill is provided in a wind path.
The southerly wind that hits the solar windbreak wall is gathered into the sky along the panels and increases in force. By using this wind to rotate the wind turbine WM and use the rotation of the rotating shaft to directly or indirectly rotate the generator EG and obtain generated power, it is possible to obtain wind power in addition to solar energy. . The vector of horizontal wind power is sin θ of the elevation angle θ, but since the receiving area is large, the wind gathers and a large force moves the wind turbine WM, which has the advantage of being able to obtain energy even when there is no sunlight at night or when it is cloudy. I can do it. The figure shows an example of a windmill with a structure that lies horizontally and rotates due to drag, constantly receiving wind uniformly through concave blades and twisting. Unlike vertical windmills, because they are horizontal and fixed at both sides and in the middle, they can generate a large amount of electricity without worrying about them falling over or breaking.

In Figure 14, the wind that hits the solar cell windbreak wall surface is collected in the sky and rotates the windmill WM, but since the height lh1 of the windbreak wall panel is compressed by the wind path lh2 that rotates the windmill, the wind per unit time is Let the speeds of be v1 and v2, respectively, then the air volume v1lh1=v2lh2, and the speed of the wind hitting the windmill v2≈(lh1/lh2)v1, which becomes a strong wind speed and increases the rotational force of the windmill, P=(1/2)ρv2 ² Powerful xS2 power generation is possible. The wind turbine of the present invention is characterized by increasing the speed of the collected wind, generating electricity even in weak winds that always blow, and being resistant to damage.

FIG. 15 shows an embodiment of a device for automatically controlling the wind inlet of a wind turbine. In addition, in winter, to prevent snow damage and freezing, a heating wire is installed in the center of the rotating shaft to melt snow and ice on the blades.
Normally blowing wind has a wind speed v of about 2 to 5 m/sec, but when it becomes strong, the wind speed v=20 to 30 m/sec.
Since the wind pressure is p=1/ ^2ρv2 , the wind pressure load increases as the square of the wind speed, so the wind turbine breaks or the wind pressure load increases, causing the shaft to break or bend.
For example, if the wind speed v=2 m/sec becomes v=20 m/sec, the wind pressure will be multiplied by the square, so it will be 100 times greater, and you will be exposed to an incredible wind pressure. It is desirable to have a structure that can withstand this difference, but it is also necessary to stabilize the wind pressure load by controlling the wind inlet and making the inlet smaller in strong winds to prevent destruction. becomes. In other words, as mentioned earlier, the wind pressure load W is W = 1/2ρv ₂ ² h ₂ l ₁ since the wind receiving surface S2 = h ₂ l ₁ , so in order to suppress the wind pressure load, h ₂ must be made small. The choice is to make l ₁ smaller, or to make both smaller. A governor or the like is used to automatically control the rotation speed, but this also has its limits. It is also possible to change the rotation speed by automatically applying the brakes or changing gears using sensors.
As an example, for the sake of simplicity, an example will be shown in which the size of the wind inlet and the window are automatically rotated depending on the strength of the wind to control the size of the wind inlet.
It can be seen that in the case of normal wind of 2 to 5 m/sec in the figure (a), and in the case of strong wind in the figure (b), the control blade CW is lowered and the air intake becomes smaller. The structure is such that a rotating window is installed on the outside of the windmill, and the size of this window is adjusted using a rotating shielding plate. The size of the wind entrance can be adjusted by rotating the shield plate by an angle that is determined by the strength of the wind. The rotating force is generated when the wings CW directly connected to the arm a receive the wind and are automatically pushed downward, which also rotates the shielding plate and reduces the size of the window. As the wind becomes stronger, the blade CW is lowered downward and the amount of wind entering the wind turbine becomes smaller as shown in Figures (c) and (d).
When the wind weakens, the spring lifts arm a, increasing the amount of air entering the windmill.
When the wind blows, the force of the spring and the wing CW alternately generate downward stretching force, which causes natural vibration, so a damper or brake is installed to suppress the vibration.
Unlike a lift-type propeller, it has a horizontally elongated drag-type blade, which disperses the force and makes it difficult to break. Regarding the size of the window, it is possible to have a structure in which not only the length ε of the intake port is changed, but also l1 is equivalently changed as shown by the broken line. The rotating shaft is double or triple layered, and a heating wire is inserted in the center to prevent the rotating shaft and blades from freezing.

FIG. 16 shows an example of power generation using a propeller-type lifting wind turbine suitable for high-speed rotation. The wind is dispersed to both sides and devised to avoid wind damage to the greenhouse and greenhouse 3 in the rear. The feature is that the collected wind is further condensed to rotate a lift-type windmill or turbine to generate electricity. The wind turbines shown in Figures 13, 14, 15, and 16 will be installed north-south and east-west as appropriate.

Figure 17(a) shows power generation by a windmill. This shows that a generator is attached to a horizontal windmill to generate electricity.
There are two types of windmills: drag type and lift type, and either type can be used.

In Fig. 17(b), the mechanical rotation of the windmill is used as it is, a worm gear is used as the rotation axis to transmit the rotation to a perpendicular axis, and this rotation is further transferred to the bevel gear (2-6). 2-7) is used to rotate an indoor fan (2-8).
In the case of worm gears, a reduction effect can also be implemented.

Figure 18(a) is a special example in which the solar cells that form the windbreak wall and roof (described later) are installed on the south side, the solar cells are placed below, and the solar cells are sparsely attached to a transparent plate such as tempered glass. An example in which a solar cell is provided above is shown.
Figure 18(b) shows windbreak walls made of reinforced glass, transparent plastic, etc., which serve as solar cells and transparent solar cells, installed in the north and south, and east and west. When constructed, the exterior appearance will be an integral structure that surrounds the entire building. Hot water heated by a solar water heater is piped to heat the entire greenhouse, which is useful for growing plants, keeping warm, and melting snow.

FIG. 19(a) shows an embodiment in which a solar cell and a solar water heater are integrated.
Basically, solar cells themselves generate heat by adding power generation from sunlight, heat loss, heat from infrared rays, and heat generation from solar cell current. Monocrystalline solar cells are black in color, so they heat up when exposed to sunlight. Solar cells are made of PN bonds and are semiconductors, so if the heat gets too high, their performance will drop. Useful for melting snow in snowy areas.
Since solar cells can obtain a voltage of about 0.5V from the energy of sunlight, the voltage can be increased by connecting the cells in series. Therefore, basically both the back side and the front side must be insulated. Commercially available solar cells are insulated with resin or plastic, so a metal tank or pipe can be stretched almost closely behind them. Ceramic, plastic, metal oxide, etc. can be used as the insulator. Some metal oxides are insulators, so it is also possible to cover the metal surface with the oxide and then attach and fix the solar cell on top of it.
FIG. 19(a) shows an example in which a solar cell is pasted on the front surface and a solar heat absorption tank 4 is disposed on the back surface with an insulating layer Ins interposed therebetween. Conventional insulating layers can be used, but the thinner the insulating layer, the better the heat transfer efficiency. As mentioned above.

FIG. 19(b) shows a cross-sectional view of FIG. 19(a).
There are solar cells on the left side, an insulating layer in between, and a water heater surrounded by metal on the right side. For the electrical wiring section, it is best to make a recess in the bottom of the tank, which will serve as the hot water tank, for wiring.
Although not shown in the figure, it is also possible to cover the whole or the water heater with a glass to prevent conduction and convection in order to create a vacuum. In this case, the structure becomes more robust, but the cost increases. The heat from the water heater at the rear helps melt the snow that accumulates on the surface of the solar cells in the winter, making it possible to use the system in the winter. In some cases, hot water may be heated using electricity or the like.
FIG. 19(c) shows a method opposite to that shown in FIG. 19(b) in which a hot water device is placed on the surface of the solar cell to generate hot water.
Figure 19(c) shows a method in which hot water is produced in the front by enclosing water sandwiched between glass, reinforced glass, or transparent plastic plates on the front sunlight-transmitting surface. FIG. 2 is an explanatory diagram using a cross-sectional view of this structure. The water is also transparent, allowing sunlight to pass through, and when supplying hot water, it plays a role in melting snow.
FIG. 19(d) shows a case in which a heating wire layer is provided on the front or rear surface of the solar cell to provide the function of melting snow or ice by generating heat from electricity.

FIG. 20 shows a case where a two-dimensional parabolic surface is used as a reflecting mirror to collect sunlight and simultaneously perform solar power generation and solar hot water generation.
The straight portion of the parabolic surface may be covered with transparent glass or plastic such as polycarbonate to allow wind to escape to the top.
FIG. 20(a) is a perspective view, and FIG. 20(b) is a sectional view.
FIG. 20(c) is a cross-sectional view of the light receiving section.
FIG. 20(d) is a diagram of a curved surface.

FIG. 21 shows an example of sunlight utilization in which one solar cell and a solar water heater 4 are attached on the same surface.
Figure (a) shows solar cells arranged above a solar water heater.

FIG. 22 shows an example in which a solar power generation cell and a solar water heater integrated unit are configured as a windbreak wall.
Figure 22(a) is an example in which one side is made up of one piece, which is difficult due to its large size, so an example of making a windbreak wall by combining integrated units and attaching them to the side as shown in Figure 22(b) is shown. show.
The wiring for the combination of solar cells and the connection of the hot water pipe of the solar water heater will be omitted.
FIG. 22(b) shows a case where integrated unit segments are arranged and the segments are combined according to the size of the entire panel.
Each symbol indicates 1 solar cell, 2 windmills, 3 greenhouses or plastic greenhouses, and solar water heaters 1 and 4.

FIG. 23 shows an embodiment in which one solar cell part and four solar water heater parts are separated and attached to the same sloped surface that serves as a windproof surface.
Fig. 23(a) shows an example in which a heavy solar water heater is provided below and a solar cell is provided above, and Fig. 23(b) shows an example in which a solar water heater is provided above and a solar cell is provided below. . If a water storage tank is provided, a portion of the water storage tank may be provided beside the two wind turbines.

FIG. 24 is an embodiment having almost the same purpose as FIG. 23, but is an embodiment in which a windproof surface is installed separately for solar power generation and a solar water heater. 24(a) and (b) are almost the same, but the difference is whether the entire length of the windmill is used for the windbreak surface, or the upper part is used separately from the water reservoir of the water heater.
Figure 23 shows an example in which side 1 of the solar cell and side 4 of the solar water heater are arranged separately, and the hot water tank is heavy, so it is placed at the bottom (a), and the solar water heater is placed at the top to make it easier to flow. and shows the case where the tank is placed at the top.

Figure 25 is an example of an embodiment in which the gable side faces south.The south side generates solar power and wind power is generated on the upper side, and the east and west sides have solar cells sparsely arranged to reduce the amount of sunlight in the lower positions in the morning and evening. This is an example in which wind power generation is carried out with a transparent plate for the purpose of windbreak shielding so as not to block the wind, and on the north side there is a solar water heating system and solar cells that do not need to worry about shade, and a windbreak wall against north winds.

Figure 26 is an example of an embodiment in which the side faces the south, and by sparsely arranging cells on the windbreak wall on the south side and in a part of the upper part of the solar cells, sunlight can easily pass through to the greenhouse or vinyl house in the rear. House tries not to cast any shadows. As the east and west sides are at low locations where sunlight penetrates in the morning and evening, consideration was given to the placement of transparent plates or cells. The north side is the same as the previous figure.
Depending on whether both sides are gables as shown in Figure 25 or side faces as shown in Figure 26, and which direction the wind is blowing from, the configuration of the windbreak surface may differ. The composition will be different.
In addition, the way to use the area below the windbreak wall panel is different, but instead of lining up solar cells and using it only for power generation as in the past, wasting a small amount of land, it can be used for solar power generation, heat generation, water heaters, and wind power. It is now possible to utilize all of the heat generated by comprehensively utilizing the heat, unlike in the past when the heat was simply left out in the open to escape.

FIG. 27 is an example showing how the use of sunlight and wind can be optimally performed by configuring a greenhouse or vinyl greenhouse as described below for the configuration of a typical farmer's rice field.
The size of an average farmer's rice field is 300 tsubo, and the area is 20 m facing south and 50 m long from east to west, making effective use of the area.
A field of this size has a southward length of about 20 m, and wall panels made of solar cells are installed along this length at an angle of about 45 degrees.
Approximately 2 to 3 greenhouses or vinyl greenhouses with gable sides will be constructed behind this with a gap G between them. The site area of the house is approximately 200 tsubo, and the length of the gable side of each house is 6 to 8 m, so whether to set it at 8 x 2 = 16 m or 6 x 3 = 18 m depends on the plants inside and the surrounding area. It also adjusts depending on the construction of the panel.
FIG. 27(a) shows the arrangement viewed from the top. Regarding the windbreak wall on the south side, G is placed between the windbreak wall and the greenhouse so as not to shade the greenhouse as much as possible.
On the other hand, regarding the windbreak walls on the east and west sides, the sun in the morning and evening has a low elevation angle and does not produce strong solar radiation, so we prioritized the windbreak effect, so we placed the windbreak walls with solar cells arranged on transparent plates vertically instead of laying them down too much. Respond to sunlight.
Regarding the windbreak wall on the north side, it blocks the north wind and generates wind power from the north wind, and there is no need to consider the negative effects of the windbreak wall, so it is possible to use solar cells to generate both electricity and hot water by installing a solar water heater. The floor plan is appropriate.
Generally, the house is equipped with an air conditioner, air control, and environment controller, but since this interferes with the effective use of the house, the space can be used effectively by solar power generation or by using the space below the water heater. This makes it possible to make effective use of Japan's limited land.
The space below can also be used to farm animals such as chickens and other creatures.
In addition, heat generated by solar power generation is generally lost by heating the air when exposed to the open air, but with the present invention, it can be effectively used to control the temperature inside the greenhouse. Energy can be used effectively without wasting it.
It is desired to create a rich and sustainable environment by reducing CO2 and using natural energy, but by growing plants in the sun, we can obtain starch and convert CO2 into glucose and starch, which helps maintain life and function. It is possible to achieve a circular environment and food self-sufficiency by creating and protecting an environment for obtaining energy, and by using solar power generation, solar heat, wind power, or geothermal energy.

FIG. 28 shows a method of integrating solar battery panels on the wall of a greenhouse or vinyl house.
As shown in Fig. 1, which is a cross-section of the greenhouse viewed from the side that receives the wind, the part of the greenhouse that receives the most wind pressure is the part that stands flat and vertical, and receives the wind directly. The wind pressure coefficient is close to 1. The roof portion 3-R, which is round, triangular, or has a plane parallel to the wind, has a low wind pressure load because the wind can easily escape and the wind force coefficient is low. The solar cell surface is shown diagonally to increase the light receiving area and reduce wind resistance, but it may also be built vertically as a wall of a structure, although the power generation efficiency will be lower. Therefore, the windbreak wall can be used as is, vinyl, plastic, glass, and building materials on the vertical parts can be eliminated, and the solar cell windbreak wall can be used as a part of the house to create a sturdy structure. In addition, solar cells can be used. Regarding the east and west sides, as mentioned earlier, the light in the morning and evening is weak and the sunlight comes from a low altitude, so solar cells are sparsely arranged for economical reasons.
House control equipment can be installed in the shade below the solar panels on the south side or under the windbreak panels on the north side, making effective use of the space inside the house. Wasted space can be utilized and a robust structure can be created. Heat can also be used effectively.
The use of wind power, water heaters, etc. are the same as described above. The hot water heated by the water heater heats the interior through piping, and is effective for raising plants, melting snow, and melting ice.
For the roof, a vinyl sheet for a vinyl house, glass, a transparent plastic plate, a transparent solar cell, etc. can be used, and a conventional material such as a pipe can be used as the beam B for holding the roof 3R.
The beams that support the roof across the roof can be reinforced by distributing the load on the walls due to crosswinds to the walls on both sides, as well as the north, south, east, and west walls, creating a stronger structure than supporting the roof from one side. Figure 28(a) shows the case of a flat roof, where sunlight passes above the four walls.This roof is supported by beams such as pipes, and the upper part of the roof that the walls support Torque due to wind pressure loads can be supported by the front and rear walls.
FIG. 28(b) shows a case where solar cells are arranged along the conventional shape of a greenhouse or vinyl greenhouse.
The finished structure is almost the same as the previous one, so it doesn't feel out of place.
The roof portion 3-R similarly transmits light and does not receive much wind pressure, so it can be left as is. To withstand snow and hail, it is better to use a material that is a little more durable, such as polycarbonate, a tear-resistant plastic material, or glass.
The curved roof has the same structure as the conventional structure, but the pipes that serve as beams B support the roof material 3R and support the front, rear, left, and right walls on both sides or the entire surface, making the structure strong, free from wind damage, and protected from snow. It has a structure that can withstand rain, etc.
As is clear from the comparison with FIGS. 25, 26, and 27, the use of space by integrating is large, materials can be omitted, and the wind pressure load can be supported by the beam and the walls on both sides, which is a great advantage.

FIG. 29(a) shows a case where the area below the solar power generation panel is used as a field when generating solar power and growing plants on the rooftop of a building for self-sufficiency or as a hobby.
The solar power generation panel may be a transparent panel in which cells are arranged as described above, or a light sheet-like translucent amorphous solar cell sheet. It is better for rooftop structures to be lightweight. The framework is made of aluminum angles, pipes, and channels, and amorphous solar cell sheets can be used to make it lightweight. It can be rolled up and stored when the wind is strong. Windmills will be used as appropriate.
A solar panel windbreak wall is set diagonally toward the south near the roof, and is suspended from the rooftop or the ground to generate solar power and plant and grow plants below.
It can be used as a place for relaxation for people living in buildings or condominiums, and it can be used to generate electricity from solar power generation or sell electricity.It also helps reduce CO2 emissions, so the roof of a building is useful and allows people to have a relaxing time. As shown in Figures a-b, amorphous solar cells have lower efficiency, but are lighter and can be rolled up and stored.
The greenhouse itself is constructed with partially transparent solar panels or semi-transparent solar panels, and as an example, it has a structure with a sloped roof on one side and covers the entire structure, but in this case, the solar panels You can build a greenhouse by This shows the case covered with a single-sided sloping roof.
Although the figure shows a transparent or translucent solar cell panel on one side, a similar structure can be implemented on other sides. This figure shows the case where the greenhouse is configured with wind in four directions.
By using direct sunlight, power from solar cells, and wind power, it is possible to maintain an appropriate temperature even at night, on cloudy, rainy days, and in winter by using the air conditioner inside the house.
Unlike wind power generation, which simply uses the cross section of a wind turbine, wind power generation systems collect the wind that hits the panels and let it escape, and this wind is then collected to generate wind power, resulting in a large power generation capacity.
Figure 29(b) shows the conventional method of installing solar cells that has been installed up until now, where there is a gap between each solar panel and the adjacent solar panel. Plants can be grown enclosed in windproof and insulating materials such as vinyl sheets.
Because solar cell equipment uses land exclusively for the sole purpose of generating electricity, much of the land is taken away from agricultural land for other purposes.
We would like to solve this problem, make it possible to generate solar power, and provide space that can be used for agriculture to produce arable land and plants. The distance G between the solar panels is about 1m, and during the day the sunlight shines in, brightening the surrounding area and helping the surrounding area as well.
Translucent solar panels can also be used to maintain an appropriate temperature without inhibiting plant activity.
The solar cells are installed at a gentle slope and act as a roof, and the heat generated is collected in the space below.
The panel is a unit, so this unit is fastened to the pipe below via an aluminum edge frame, and since there is a gap between adjacent panels, a T-shaped inset type is used to fill this gap. By using a sealing material made of metal or plastic, it is possible to seal the area and prevent air flow and insect intrusion. This has the advantage of being able to use some of the electricity generated by solar cells and some of it for growing plants.

Figure 30 is a book on how to improve the environment for plants in greenhouses and plastic greenhouses using the solar power generation of the present invention, reduce CO2, suppress temperature rise, and realize the SDGs of a sustainable society. FIG. 2 is a block diagram showing a specific configuration of the invention.
Although the inclination of the solar panel, the structure as a windbreak wall, the use of the space below, etc. are not shown in this figure, they are clearly explained in the explanations of other figures.
The upper left shows the solar battery panel 1, the upper middle part shows the windmill 2, the upper right part shows the solar water heating system 6, and the middle part shows the green house or plastic greenhouse 3, sunlight 5 and wind 6, and electricity. The control system and transmission/reception are shown at the power conditioner 12, the auxiliary generator at 14, the charger at 8, the power control at 13, the air conditioner at 15, the environment controller in the house at 16, and the heater at 4 and 5. In some cases, large equipment such as an air conditioner may be prepared to blow only air into a vacant room below the windbreak panel of the house. The same applies to other devices.
In addition to using solar cells 1 to control the house 3, we also use solar water heaters 4, wind power generators 2, geothermal power generation 10-2, hot springs, steam, etc. 10, and use the generated electricity for air conditioning. Indicates a system that can be used effectively for equipment and environmental control, as well as for selling, receiving, and charging electricity.
In addition to solar cells 1, wind power generation 2, and geothermal power generation 10-2, it is conceivable to use the heat itself for hot water, etc., and use it as a power source for heating, power generation, and mechanical movement.
By equipping the facility with a generator that uses gas or other electricity, it can be used as a temporary power source in case of an emergency.
In addition, you can use the space under the south and north windbreak walls as a room for breeding animals, and you can also use the heat generated by solar cells, the heat from water heaters, and some sunlight to grow plants. good.
When solar cells are used as a windbreak wall or roof, or when the lower part is mainly used, efficient use can be made by considering appropriate combinations of the main power generation, hot water, wind power, etc.
By integrating a greenhouse or vinyl greenhouse using solar cells and solar walls, energy can be used efficiently in addition to solar cells, wind power, and solar heat.

The conventional way of thinking is to install solar cells on a wide flat area, with the sole purpose of obtaining electricity from sunlight, and to avoid creating shadows, install the solar cells not at too much an angle with the ground and without slope. . For this reason, it cannot be used as a windbreak wall, while greenhouses and vinyl greenhouses require electricity for temperature control such as air conditioning, air circulation, CO2 control, sunlight control, etc. It takes up a lot of land because solar panels are laid out all over the land regardless of whether it is a greenhouse or a plastic greenhouse.
When strong winds blow, vinyl greenhouses are exposed and can be blown away, destroyed, or distorted. 80% of disasters are caused by wind damage, and solving this problem will help agriculture and promote development. This is the path to realizing a sustainable society, securing food, and reducing CO2 emissions.The effective use of sunlight is a logical way to use natural energy and preserve the environment. Protecting greenhouses from destruction will help eliminate waste and improve economic efficiency, which will have the effect of killing two birds with one stone, and is expected to be used for industrial and safety reasons.
The energy of sunlight is approximately 1 kW/m ² , but currently only 20% (200 W/m ^{2 )} or less is used for solar power generation, which is around 150 W/m ² .
80% of the energy is lost as heat or reflection loss, so if heat loss can be utilized, it will be a savings.
By making comprehensive use of these, we can provide plants with a comfortable environment without relying solely on power generation.
Furthermore, many solar panels have been installed to utilize natural energy, which is putting pressure on farmland and forests.
If the land below the solar cells and the empty space between the neighbors can be used for farmland, etc., or for poultry farming, productivity can be further increased.
