Description

The present invention relates to a light receiving device and a power generation device using three-dimensionally arranged solar battery surfaces.

Usually, in power generation using a solar cell, a solar cell surface is arranged in a substantially flat shape on a roof or the like to receive light and generate power, and when excess power is generated by a conditioner device with an inverter function, it is sent to a commercial power line for sale. In this method, power is sold when surplus power is obtained, and power is obtained from a commercial power line when power is insufficient.

The solar cell surface arranged in a plane on the roof or the like does not always cause light to strike the solar cell surface vertically due to the movement of the sun, and the amount of light received from morning to evening in the day is considerably small.
In the solar cells installed in this way, generally, the amount of power generation in the solar cells arranged in a substantially planar manner in this way is about 3 to 4 hours per day on average.
Further, in the light reception of the solar cell surface arranged in a plane on the roof or the like, the solar altitude varies depending on the season of spring, summer, autumn, and winter, and therefore the light is not always vertically applied to the solar cell surface.

When a solar cell is installed on a gantry and the solar cell surface is tilted according to the summer solar altitude, solar light can be received almost vertically on the solar cell surface during the summer, but in the winter The light from the sun is irradiated obliquely on the battery surface, and the power generation efficiency of the solar battery is greatly reduced.
On the other hand, when the direction of the solar cell surface is adjusted to the winter solar altitude, solar light can be received almost vertically on the solar cell surface during the winter, but if you use the solar cell in this state even in summer, The light from the sun is received from an oblique direction, and thus the power generation efficiency of the solar cell is greatly reduced due to the difference in season.
Therefore, although the inclination of the solar cell surface was periodically changed manually by a person so as to make the light receiving angle from the sun as perpendicular to the solar cell surface as possible, it took a lot of labor.

Various methods, such as solar tracking and solar tracking, in power generation using solar cell surfaces arranged in a plane on the roof, etc., power generation using solar cell surfaces installed on a gantry, and solar cell generation in a limited occupation area There is a power generator. In these systems, control is performed such that the solar cell surface is always moved in the solar moving direction by an electric motor or the like so that the sunlight is received perpendicularly to the solar cell surface. These not only require difficult three-dimensional control and expensive capital investment, but also have the problem of being vulnerable to snow and wind pressure for use outdoors. In addition, in order to overcome the problems caused by wind pressure and snow accumulation, it was necessary to use a device with a sturdy structure.

In power generation that moves in the solar direction in solar tracking, solar tracking, and the like, the amount of power generation can be about 1.6 to 1.7 times that of a solar cell with an occupation area that is arranged substantially horizontally.
In this method, the light is always received substantially perpendicularly to the solar cell surface, so that a substantially constant amount of light is obtained, but the amount of light received depends on the weather, the amount of water vapor, dust, etc. It is not always uniform.

No other method has been found to increase the amount of power generation per occupied area by the movement of the sun from east to west during the day and evening of the day and the change in the altitude of the sun during the spring, summer, autumn and winter seasons.

Already in exhibitions and markets, there is a power source for a light receiving device or a power generating device of a type in which only the solar cell surface facing substantially upward is provided at the tip of a support as shown in FIG. This type of light receiving device has different sun altitudes, sunrise and sunset directions due to changes in sun altitudes during the day, during the day and at sunset, sun movements, and spring, summer, autumn and winter seasons. In addition, the light receiving efficiency is considerably low.
A light receiving device or power generation device of a type in which only a solar cell surface facing substantially upward is provided at the tip of a support column can be said to be a small version of a solar cell arranged in a plane on a roof.

As shown in the graph of FIG. 2, the light receiving power generation of the maximum value can be performed during the daytime in the morning and evening of the day, but the power generation is considerably low in the morning and evening. Therefore, no matter how wide the solar cell surface is provided in a planar shape, it only becomes a similar shape to the graph of received light amount in FIG. 2, and the light receiving power generation efficiency is not good.

In addition, if there is snow on the solar cell surface 1 facing substantially upward at the tip of the column in FIG. 1, no light receiving power generation can be performed.

Until now, there has been no application for solar cells that three-dimensionally receive sunlight.
Patent Document 1 is a power generation device using a “foldable solar-following solar cell”.
JP 2010-219318 A

As described above, in the light reception of the solar cells arranged in a plane, not only the altitude of the sun changes depending on the morning, daytime and evening of the day, but also the altitude of the sun changes due to seasonal changes in spring, summer, autumn and winter. The amount of power generation changes significantly.

Light reception that generates electricity that can secure a certain amount of light reception in a certain occupied area even in the morning, daytime, and evening sun "altitude changes" in the day and changes in "sun altitude" in spring, summer, autumn and winter The advent of devices, power generators, and power supplies was awaited.

Even in the morning, daytime, and evening “movement of the sun” in a day, the amount of light received is high and the amount of light received is substantially constant or more, and a certain amount of light received is ensured in the area occupied by a certain solar cell surface. The power supply of the power generation method that can be waited.

In the light reception of the solar cell surfaces arranged in a plane, even if the size of the solar cell is doubled, the light reception amount is similar to the graph as shown in FIG. 2, and only the light reception amount during the day protrudes and increases. However, the amount of light received in the morning and evening remains drastically reduced. Therefore, if the area of the solar cell surface is increased to increase the total amount of power generation, charging by the storage battery becomes an overcurrent state during the day, which may cause deterioration of the storage battery or fail to charge all of the generated power. Therefore, while the sun is out in the morning and afternoon of one day, the power supply by the solar cell that can secure a power generation amount of approximately a certain level or more is awaited.

The change of the light reception amount by the difference in the solar height in the power supply which comprised the solar cell surface only in the substantially upward direction shown in FIG. 1 is shown.
(The amount of light received when the solar cell surface is irradiated with light vertically is assumed to be 100, and the ratio of the amount of light received without a unit is shown.)
When sunlight is incident at an angle with respect to the vertical to the solar cell surface
Angle Amount of light received only by the solar cell surface in the upward direction
0 ° 100
15 ° 96
30 ° 86
45 ° 70
60 ° 50
75 ° 26

The apparent inclination of the earth during summer and winter in the Earth revolution is 23.4 ° × 2 = 46.8 °, and the difference in the latitude of the light receiving point is added. The amount of light received only by the solar cell surface facing substantially upward varies greatly from 26 to 100. Therefore, since the sunrise position, the daytime position, and the sunset position change depending on the latitude of the light receiving point, a means for generating power with a solar cell that can make the amount of received light more than a certain level during the sunrise has been awaited.

In particular, since the altitude of the sun is low in winter, the amount of light received by solar cells installed on a roof or the like in a substantially flat shape is small and the amount of power generation is low. Even in winter, a light receiving device and a power generating device that can generate power with the same amount of power generation and light reception as in summer have been awaited.

In the light reception on the surface of the solar cell installed in a substantially flat shape, the amount of light received by the solar cell in the morning, daytime, and evening in the day is significantly different, and the amount of light received in the morning and evening is significantly reduced.
In the morning and evening, the amount of power generated in the morning and evening has been waiting for a light receiving device and a power generating device using a solar cell that can obtain a certain amount of received light that can be generated almost as much as in the daytime.

In addition, due to snow accumulation, power generation is stopped only with the solar cell surface facing substantially upward. A light receiving device and a power generation device using a solar cell that can generate power even in snow are waiting.

In a power source with only a solar cell surface facing upward, the amount of received light is the maximum when the sun is received at a high altitude of the sun and perpendicular to the solar cell surface.
The amount of light received on the solar cell surface decreases as the altitude of the sun decreases.
In the present invention, in addition to the solar cell surface facing in the substantially upward direction, another solar cell surface, which is a solar cell facing in a direction substantially perpendicular to the solar cell surface facing in the substantially upward direction. A means for providing a surface is used.

First, a solar cell surface facing substantially upward with respect to a horizontal plane, and a solar cell surface facing substantially perpendicular to the horizontal plane above or below the solar cell surface, the two A light receiving method or a power generation method is used, which is characterized in that solar light is simultaneously received on a solar cell surface facing in a direction to obtain generated electric power.

Second, a solar cell surface facing substantially upward with respect to the horizontal plane, and a solar cell surface facing substantially perpendicular to the horizontal plane above or below the solar cell surface, the two A light receiving device or a power generating device is used, which is characterized in that the solar cell surface facing in the direction receives solar light simultaneously to generate generated electric power.

Third, a solar cell surface facing substantially upward with respect to the horizontal plane at the top end of the support column, and a solar cell surface facing substantially perpendicular to the horizontal plane on the side surface of the support column, the two directions By means of a light receiving device or a power generating device, the solar cell surface facing the solar cell simultaneously receives solar light to obtain generated electric power.

Fourthly, the solar cell surface facing substantially upward with respect to the horizontal plane at the top end of the support column, and the solar cell surface facing substantially perpendicular to the horizontal plane on the side surface of the support column, at least the substantially vertical The solar cell facing in the direction is rotated in the horizontal direction about the support column as a center, and the solar cell surface facing in the two directions is simultaneously received by receiving solar light to obtain generated electric power. It depends on the features of the light receiving device and the power generating device.

Fifth, a solar cell surface facing substantially upward with respect to the horizontal plane at the top end of the column, and a solar cell surface facing substantially perpendicular to the horizontal plane on the side surface of the column, the substantially vertical direction The solar cell surface facing toward the solar cell is disposed so as to surround the support column, and the solar cell surface facing in the two directions is simultaneously received by receiving solar light to obtain generated power. It depends on the means of the light receiving device and the power generation device.

Sixth, a solar cell surface facing a substantially vertical direction on a three-dimensional columnar upper surface and a solar cell surface facing a substantially vertical direction on a three-dimensional columnar side surface, and facing the two directions By means of a light receiving device or a power generating device, which simultaneously receives sunlight and obtains generated electric power.

Seventh, a solar cell surface facing in a substantially upward direction on a three-dimensional columnar upper surface and a solar cell surface facing in a substantially vertical direction on a three-dimensional columnar side surface, the solar cell facing in the two directions The light receiving device and the power generating device are characterized in that both are rotated in the horizontal direction and the solar cell surfaces facing in the two directions receive solar light simultaneously to generate electric power.

Eighth, in the first to seventh means, the solar cell surface facing substantially upward is inclined with respect to the horizontal plane.

What is common to all the claims is that the solar cell surface is divided into two parts, a solar cell surface facing substantially upward and a solar cell surface facing substantially vertical, and installed in three dimensions. The dihedral angle formed by two solar cell surfaces is basically arranged at a substantially right angle, and when the two solar cell surfaces receive solar light at the same time, the received light is generated by the generated electric power. It is a means of a device or a power generator.

In the present invention, the type in which the solar cell surface is provided outside the dihedral angle formed by the two solar cell surfaces is the A type, and the type in which the solar cell surface is provided inside the dihedral angle is the B type.
In some cases, the solar cell surface facing substantially upward is inclined with respect to the horizontal plane.

In only the solar cell surface 1 facing substantially upward, the amount of received light is the maximum when the solar light is received perpendicular to the solar cell surface, and as the solar altitude decreases, The amount of received light will decrease.
In the present invention, in addition to the solar cell surface 1 facing substantially upward, the solar cell surface 3 facing the substantially vertical direction, which is another solar cell surface, is combined and provided. As the amount of light received on the solar cell surface 1 facing in the direction decreases, the amount of light received on the solar cell surface 3 facing in the substantially vertical direction increases conversely. Therefore, there is an effect that it is possible to obtain a light receiving amount of a certain level regardless of the height of the sun.

In the experiment from the day when the sun rises until the sun sets, the amount of received light greatly increases and decreases by 22 to 100 as shown in FIG.

In the experiment of FIG. 6, the sum of the amount of light received by the solar cell surface 1 facing substantially upward and the amount of light received by the solar cell surface 3 facing substantially vertical regardless of changes in the altitude of the sun during spring, summer, autumn and winter. Has an effect of obtaining a converged light reception amount that does not greatly increase or decrease as the solar altitude changes from 122 to 141.

In the experiment of the apparatus of FIG. 8 according to the present invention, when the sun rises from the east and passes directly above and sinks to the west, the sun moves and there is an effect that the light source can always obtain an amount of received light of 100 or more. . (The light receiving angle was 15 ° to 165 °.)
At sunrise and sunset, the light is greatly diminished because the sun's light passes diagonally through the atmosphere on the tangent line of the earth, the mountains, distant clouds, but if you ignore these, As a result of the investigation experiment during the movement of the sun that the sun rises from just east, passes almost directly above, and sinks to the west, 100 to 141 converged substantially constant amount of received light was obtained.

As shown in the right side view of FIG. 8, the amount of light received in the above 100 to 141 is a numerical value when the sun rises from just east, goes straight above, and sinks to just west. When the sun is directly above the solar cell surface 1 facing substantially upward, the received light amount is obtained only on the solar cell surface 1 facing substantially upward, and the received light amount is 100.
However, in most parts of Japan and the rest of the world, the latitude is not 0 °, the position of the sun is not perpendicular to the solar cell surface 1 facing upward, and the sun always maintains an oblique altitude. Yes. Therefore, in the south direction (90 °), the solar cell surface 3 facing in the substantially vertical direction with respect to the horizontal line and the solar cell surface 1 facing in the substantially upward direction receive light, so that the altitude of the sun is 45 °. In this case, the maximum amount of light received when solar light is simultaneously received on the solar cell surfaces facing in the two directions is 141.

  Accordingly, the actual received light amount in the region where the latitude is not 0 ° is 100 in the morning and evening as shown in the graph of FIG. 7, but the minimum received light amount of 100 in the morning at 90 ° is not necessarily 100%. It is not a stepped mountain, and the amount of received light can be 141 at the maximum. Therefore, in Japan, compared to the values of 100 to 141 even during the day, there is an effect that a more converged light reception value can be obtained.

In the light receiving device or power generation device with only the solar cell surface 1 facing upward, a difference in the amount of received light also occurs due to a difference in altitude of the sun with a difference in latitude of the place of use.
In the power source of the present invention, the solar cell surface 1 facing substantially upward and the solar cell surface 3 facing substantially vertical are provided, so that the latitude of the place where the apparatus is used is high or low. An amount of light received above a certain level can be secured, and there is an effect that the problem that the amount of received light changes greatly due to the difference in latitude in the sales area does not occur.
Therefore, it is possible to produce and sell a product in which all products are made uniform without creating individual products due to differences in latitude.

By including the solar cell surface 1 facing substantially upward and the battery surface 3 facing vertically, the light receiving device or the power generation device can be used from a high latitude region to a low latitude region.

If the sunrise position in the morning and the sunset position in the evening in spring, summer, autumn and winter are not taken into consideration, the amount of received light can be secured at a substantially constant level or more even in the change of solar altitude and the movement of the sun in spring, summer, autumn and winter.
In addition to the solar cell surface 1 facing substantially upward, the solar cells 3 facing substantially vertical are provided in a plurality of directions of east, west, south, and north, or by horizontally rotating the solar cells 3 facing substantially vertical, Light can be received from morning sun to daytime to sunset. The solar cell surface and solar tracking solar cell that receives light by controlling the solar cell surface in the direction of the sun can obtain substantially the same effect. Because it is possible to receive light from the morning sun to the sunset, you can get a large total amount of power generated by multiplying the time value in one day.

By making the solar cell into a three-dimensional shape having two surfaces, a solar cell surface 1 facing substantially upward and a solar cell surface 3 facing vertically, the solar cell surface 1 facing upward is obtained. If it is installed substantially horizontally upward, the area of the solar cell surface facing upward becomes the occupied area of this power supply, and there is an effect that a certain amount of received light can be secured in a certain occupied area.
On the surface of the solar cell facing in the vertical direction, the thickness of the solar cell becomes a part of the exclusive area, but the area is slight.

The amount of light received by the solar cell in a certain area over a certain occupied area has an effect that a light amount of approximately 100 or more can be obtained even in the morning sun and sunset.

In a certain occupied area, a light receiving device and a power generating device having high light receiving efficiency and a long light receiving time from morning to evening were obtained. Therefore, there is also an effect that the solar cell surface can be made relatively small in a power source that obtains a constant power generation amount.

In the B type shown in FIG. 18 and FIG. 19, the solar cell surface 1 facing substantially upward and the solar cell surface 3 facing substantially vertically above or below the solar cell surface are provided. In a power source that simultaneously receives solar light on the solar cell surfaces facing in two directions, there is an effect that it can be expected to obtain an amount of light received by reflected waves in addition to light reception by direct sunlight.
18 and 19, the reflected light from the solar cell surface 1 facing substantially upward is received by the solar cell surface 3 facing substantially vertical. Further, there is an effect that the reflected light from the solar cell surface 3 facing in the substantially vertical direction is received by the solar cell surface 1 facing in the substantially upward direction.

Even when there is snow on the solar cell surface 1 facing substantially upward and no light is received, no snow is accumulated on the solar cell surface 3 facing substantially vertical, so the solar cell surface 3 facing substantially vertical There is an effect that the light reflected by the snow surface can be received.

Since the solar cell surface facing substantially upward is fixed to the top end of the column or the three-dimensional columnar upper surface, the solar cell surface facing substantially vertical is fixed to the column and columnar side surface, Compared to the sun tracking and sun tracking, which are movable parts, they are more resistant to snow and wind.

With the present device comprising the solar cell surface 1 oriented substantially upward and the solar cell surface 3 oriented substantially vertically, the area of the two solar cell surfaces can be made relatively small. Therefore, by making the solar cell surfaces 1 and 3 small, there is an effect that the influence of wind pressure due to the solar cell surfaces 1 and 3 is less likely to occur.

In a storage battery, rather than performing rapid charging only during the day, storing a proper amount of constant electricity in the battery for a long time that lasts in the morning, noon, and evening will prolong the life of the storage battery and make the deterioration problem less likely to progress. There is a good effect from the viewpoint.

According to the present invention, simple two-dimensional control for rotating the solar cell surface 3 in the vertical direction in the horizontal direction may be performed. The conventional three-dimensional control that is difficult to follow, such as the sun tracking and the sun tracking type, has been eliminated.

Hereinafter, the grounds and reasons for the above effect of the amount of light received by the solar cell at the incident angle of sunlight will be described with reference to FIGS. 4, 5, 18, and 19.
The experiment was conducted by fixing the solar cell surface 1 facing substantially upward with respect to the horizontal line and the solar cell surface 3 facing substantially vertical with respect to the horizontal line on the assumption that θ = 90 °.

FIG. 4 (A type) and FIG. 18 (B type) show the state of the sun at approximately south-central time in summer.
The altitude of the sun is higher than in winter, and the sum of the incident angle α1 and the incident angle β1 is α1 + β1 = 90 °.
FIG. 5 (A type) and FIG. 19 (B type) show the state of the sun in the middle of winter in the south.
The altitude of the sun is lower than in summer, and the sum of the incident angle α2 and the incident angle β2 is α2 + β2 = 90 °.

In summer, the altitude of the sun is high, and the sum of the incident angle α1 and the incident angle β1 is α1 + β1 = 90 °. In winter, the sun is low, but the sum of the incident angle α2 and the incident angle β2 is α2 + β2 = 90 °. .
In other words, it was assumed that the value may be the same as when the solar light is always received perpendicular to the solar cell surface regardless of the altitude of the sun.

However, the amount of light received by the solar cell 1 facing substantially upward and the solar cell 3 facing substantially vertically (the amount of light received at each angle αβ is indicated by an underline) is α1 + β1 = α1 + β2. Don't be. Even if the amount of light received vertically on the solar cell surface is set to 100 by the function of COSθ, the solar cell facing upward and the solar cell facing vertically are evenly irradiated at a 45 ° irradiation angle. The value of the amount of received light is 141.

The output of the solar cell provides the maximum output at that light intensity when sunlight is incident perpendicular to the light receiving surface of the solar cell.
Even when the light intensity is the same, when sunlight is incident at an inclination of θ degrees with respect to the vertical to the solar cell surface (when the incident angle is θ degrees), the amount of light incident on the solar cell surface is COS (when θ = 0, COSθ = When 1.0 <| αorβ | <n / 2, the output decreases to 0 <COSθ <1).

Up to now, for example, even if the solar cell surface 1 facing substantially upward and the solar cell surface 3 facing substantially vertical are combined, it is impossible to estimate how the amount of actual direct sunlight is received. It was.

Assuming that the amount of light received by the solar cell surface 1 facing substantially upward and the solar cell 3 facing substantially vertical is α1 + β1 and α1 + β2 are substantially constant or more, the solar cell surface 1 and the solar cell The sum of the amount of light received and the amount of power generated on surface 3 was experimentally confirmed to be the same value as the amount of light received and the amount of power generated when light from the sun was irradiated at a right angle on the surface of a single solar cell.

In other words, the sum of the received light amount and the sum of the power generation amount in the two directions of the solar cell surface 1 facing substantially upward and the solar cell surface 3 facing substantially vertical are the same from the sun to the solar cell surface in one sheet. If this value is equal to or greater than the amount of light received vertically and the values at each light receiving angle converge, it is determined that this method can be used.

As a result of the experiment, both the solar cell surface 1 facing substantially upward and the solar cell surface 3 facing substantially vertical are provided in combination, and solar light is simultaneously applied to the solar cell surfaces facing the two directions. By receiving light, completely different characteristics were obtained.
The sum of the amounts of light received by the solar cell surface 1 and the solar cell surface 3 is equal to or greater than the amount of light received when light from the sun is vertically received on the solar cell surface 1 in one sheet, and a numerical value greater than or equal to a substantially converged value is obtained. It was.

The content changes, and the upper figure in FIG. 6 is an investigation of the amount of light received due to changes in the altitude of the sun.
The sum of the amounts of light received by both solar cells on the substantially upward solar cell surface 1 and the substantially vertical solar cell surface 3 was determined. Hereinafter, the ratio of received light quantity without unit is shown.
(The solar cell surface 1 facing substantially upward with respect to the horizontal plane and the solar cell surface 3 facing substantially vertical are shown using substantially the same characteristics.)
Irradiation angle Sum of received light amounts of solar cell surface 1 in the substantially upward direction and solar cell surface 3 in the substantially vertical direction 15 ° 96.6 + 25.9≈122
30 ° 86.6 + 50.0 ≒ 136
45 ° 70.7 + 70.7 ≒ 141
60 ° 50.0 + 86.6 ≒ 136
75 ° 25.9 + 96.6 ≒ 122

In this way, both the solar cell surface 1 facing substantially upward and the solar cell 3 facing substantially vertical are provided in combination, and solar light is simultaneously received by the solar cell surfaces facing the two directions. By conducting the experiment
A converged light reception amount of 122 to 141 was obtained with respect to changes in the altitude of the sun.

As shown in the lower diagram of FIG. 6, when the solar cell surface 1 in the substantially upward direction is tilted by θ2 = 30 ° so as to be perpendicular to the altitude of the sun, the solar cell surface 3 in the substantially vertical direction and the two solar cells The sum of the received light amount of the battery is the sum of the received light amounts of the solar cell surface 1 in the substantially vertical direction and the solar cell surface 3 in the substantially vertical direction.
30 ° 100 + 50 = 150
45 ° 97 + 71 = 168
60 ° 87 + 87 = 174
75 ° 71 + 97 = 168

Similarly, 150 to 174 converged light receiving amounts were obtained with respect to changes in solar altitude. As described above, the solar cell surface 1 facing upward has an effect of obtaining a larger amount of received light when the solar cell surface 1 is inclined than when it is in a horizontal plane state.

In this way, the angle of the solar cell surface 1 facing upward is set to θ2 = 30 °, for example, so that rain and snow can flow on the solar cell surface 1 at the time of designing, In many cases, the solar cell 1 facing substantially upward is given an inclination of θ2 so as to receive light perpendicularly to 1.

Further, when a power source having two solar cell surfaces, that is, a solar cell surface 1 facing substantially upward and a solar cell surface 3 facing substantially vertical, is mounted in the south direction, the change in altitude of the sun during spring, summer, autumn and winter On the other hand, there is an effect that the change in the amount of received light can be minimized by the sum of the two solar cells regardless of the difference in season.
Therefore, the solar cell surface installed on a pedestal has been adjusted to the angle of the solar cell surface according to the solar altitude in summer and winter to increase the light receiving efficiency, but such work is no longer necessary. .

Next, using only the solar cell surface 1 facing upward, the amount of light received by the solar cell was examined from when the sun rose until when the sun went down. The results are shown graphically in FIG. The vertical axis is the amount of received light, and the horizontal axis is the direction of the sun.
This is the result of a survey experiment in which the sun rises from the east, passes directly above, and sinks to the west.
The amount of light received from the sun in the east and at the west is half round on the horizon and horizon at sunrise (180 °) and sunset (0 °). Not specified.
The amount of light received at the time of light irradiated perpendicularly on the solar cell surface is defined as 100.
When sunlight is incident at an inclination of θ degrees with respect to the vertical to the solar cell surface Irradiation angle / direction Amount of light received by only the solar cell in the upward direction
15 ° 26
30 ° 50
45 ° 70
60 ° 86
75 ° 96
90 ° 100
105 ° 96
120 ° 86
135 ° 70
150 ° 50
165 ° 26
Thus, the amount of received light varies from 26 to 100 due to the change in the incident angle.

Next, in Example 2 of FIG. 8, the amount of light received by the solar cell by the present device including the solar cell surface 1, the solar cell surface 7, the solar cell surface 5, and the solar cell surface 3 facing substantially upward. The Japanese were investigated and experimented. Since the sun rises from the east, passes almost directly above, and sinks to the west, this time is the result of an investigation experiment in which the solar cell surface 3 is not used.

As a result, the sum of the amounts of light received by the solar cells in the substantially upward direction, the solar cells in the substantially vertical direction, and both solar cells is as shown in FIG.
The vertical axis represents the amount of received light, and the horizontal axis represents the sun direction, which is relative to FIG.
Irradiation angle Sum of received light amount of solar cell in substantially upward direction and solar power in substantially vertical direction 15 ° 25.9 + 96.6≈122
30 ° 50.0 + 86.6 ≒ 136
45 ° 70.7 + 70.7 ≒ 141
60 ° 86.6 + 50.0 ≒ 136
75 ° 96.6 + 25.9 ≒ 122
90 ° 100.0+ 0 = 100
105 ° 96.6 + 25.9 ≒ 122
120 ° 86.6 + 50.0 ≒ 136
135 ° 70.7 + 70.7 ≒ 141
150 ° 50.0 + 86.6 ≒ 136
165 ° 25.9 + 96.6 ≒ 122

FIG. 7 shows the amount of received light until the sun starts rising and passes just above the solar cell surface 1 facing substantially upward and sinks. Light is received by solar cell surfaces 1 and 7 from 15 ° to 75 °, received only by solar cell surface 1 at 90 °, and received by solar cell surfaces 1 and 5 from 105 ° to 165 °. To do.
