Field of the Invention The present invention mounts a photovoltaic power generation element group on various imitation plants, for example, potted parts imitating plants, leaves, branches, trunks, etc. of a plant to perform photovoltaic-electromotive force conversion. The present invention relates to an imitation plant solar power generation system that can be performed.

[0002]

2. Description of the Related Art There is a growing interest in the effective use of natural energy and a strong interest in technology for utilizing solar energy. The total energy that reaches the earth from the sun is 1.35 kW per unit area, and the theoretical total energy obtained by multiplying this value by the cross-sectional area of the earth is a huge number of 1.73 × 10 ¹⁴ kWh per unit time. Becomes Moreover, it is recognized that the use of pollution-free and inexhaustible energy, which is scarce in energy resources, is extremely important for Japan.

[0003] Conventionally widely used solar energy is a technique of utilizing it via a heat collecting medium such as water, air or oil. In recent years, however, solar power generation elements (solar battery, solar The technology of obtaining electric energy from batteries is making rapid progress. Photovoltaic power generation elements, that is, solar cells, are used for calculators and wristwatches, even if they are very small, and are widely used for solar cells, solar power generation systems installed on rooftops, etc. .

These solar energies include ultraviolet rays, visible rays, infrared rays and the like, and as described above, they can be converted into electric energy by the solar power generation element and used. As a photovoltaic power generation element, the performance of the element made of amorphous silicon has been greatly improved, and the photoelectric conversion efficiency has also been greatly improved in recent years, and the spread of photovoltaic power generation is being spurred.

The photovoltaic power generation element is usually installed on the wall surface or roof of a building as a panel in which units are appropriately combined. For street lights, guide lights and auxiliary signs installed on roads, etc., their panels are installed directly near the top.

The installation state of such a photovoltaic power generation element is as follows.
It is an efficiency-first policy, and no consideration is given to harmony with the environment or landscape.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a solar power generation system capable of performing solar power generation without damaging the landscape while considering the environment of the installation site.

[0008]

The gist of the constitution of the present invention is that a photovoltaic power generation element is arranged on at least a part of the trunk, branches and leaves of an imitation plant, and the photovoltaic power generation element is translucent. It is an imitation plant type photovoltaic power generation system that is concealed by a conductive member, and by doing so, the aforementioned problems can be solved.

As the imitation plant, those imitating various trees are suitable, but the size and the like are not limited. Depending on the conditions of the installation site, a model imitating a large tree or a model imitating a small tree can be adopted. The materials constituting these are not particularly limited. It can be made of an appropriate material such as plastic, rubber or wood. Of course, metal or the like can also be used.

A so-called solar cell is used as the solar power generation element, but the type thereof does not matter. The more efficient one is appropriate. For example, an element or the like made of the above-mentioned amorphous silicon, whose performance is remarkably improved and light-electricity energy conversion efficiency is remarkably improved in recent years, is suitable.

As described above, such a photovoltaic power generation element is arranged on at least a part of the trunk, branches, and leaves of the imitation plant, and this is performed, for example, as follows.
For example, for leaves, a recess is formed in the base material sheet that constitutes the leaves of the imitation plant to fit the photovoltaic power generation element, and the photovoltaic power generation element is fitted into the recess with the light receiving surface as the surface, and the base sheet The outer surface of the is coated with a light-transmitting film. It goes without saying that the film should be a film colored in the leaf color. A plurality of small solar power generation elements may be arranged on the leaf, or one large one may be arranged. Appropriate techniques can be used that facilitate the construction into a natural form.

[0012] Further, for example, with respect to the trunk, a concave portion into which a photovoltaic power generation element is fitted is formed around a member forming a trunk of an imitation plant, and the photovoltaic power generation element is fitted into the concave portion with the light receiving surface as a surface, And on the outer circumference of the member forming the trunk,
A covering member having a light-transmitting property and colored with the color of the trunk is covered. It should be noted that this covering member should be constructed like the epidermis of the trunk. In addition, the post-sun power generation element is configured to be fitted in a large number as necessary.

Further, the branch can be constructed in the same manner as the trunk. For example, forming a recess for fitting a photovoltaic element around a member that constitutes a branch of an imitation plant,
A solar power generation element is fitted into the recess with the light receiving surface as the surface, and the outer periphery of the member forming the branch is covered with a light-transmitting covering member colored in the color of the branch.
The covering should be constructed like the epidermis of the branch in question.

In this imitation plant, charging means for charging the electric power generated by the solar power generation element can be built in the trunk. Further, load means driven by electric power generated by the photovoltaic power generation element can be arranged inside the trunk. It is appropriate to employ an air purifying device as the load means. Of course, other means can also be adopted.

[0015]

According to the present invention, imitation plants having types, heights, trunk thicknesses, etc. in consideration of the installation environment or landscape are manufactured, and at least a part of the trunks, branches, leaves, etc. of these imitation plants are manufactured. Since we are arranging solar power generation elements, these imitation plants are
If they are installed in a suitable place, it is possible to obtain electric energy by solar power generation without damaging the environment, landscape, etc. of the installation place.

For example, if it is an imitation plant suitable for indoor use,

By the way, the electric energy obtained by the imitation plant type solar power generation system as described above can be directly supplied to an arbitrary load. However, as described above, charging means can be provided at an appropriate portion, for example, inside the trunk. By incorporating the, it is possible to correct the discrepancy between the power generation time and the load operation desired time. Of course, the same effect can be obtained by using the charging means installed outside, but in view of the installation location, it is more convenient to arrange the charging means inside the trunk. Further, it goes without saying that the use of such a charging means makes it possible to change the change in electromotive force due to changes in sunlight, illumination light, etc. at the installation location to a stable one.

Further, as described above, the load means can be built in the trunk. When configured as a pot to be installed indoors, the load means may be arranged at the root of the trunk, for example, in the pot. By adding known control means to the load means, the operation mode can be controlled. As the control mode, for example, control of load operation time, control of operating only during power generation possible time, direct operation of directly receiving electromotive force of the photovoltaic power generation element for operation, or operation switching control via charging means, etc. Can be done.

As the load means installed on the trunk or the root portion, various devices can be freely adopted, but for example, an air purifying device is suitable. Needless to say, when the air purification device is used, the air around the installation place can be purified. In this case, it is possible to form an imitation plant having a thick trunk, attach it inside it, or form it as a pot and install it inside the pot. For example,
It can be formed as an ornamental plant in pots and installed on the windowsill to purify indoor air.

Alternatively, a large-sized imitation tree is used, and it is arranged like a row of trees on the side of a road with a lot of exhaust gas to purify the air around it. Alternatively, on a winding road such as a mountain road, an automobile can step on the accelerator strongly to install it near a curve that scatters a large amount of exhaust gas to purify air. In this case, by constructing an imitation tree of a tree species that does not feel uncomfortable with the surrounding trees, it is possible to prevent the dying of the exhaust gas using clean energy from the sunlight while maintaining the natural landscape. Will be possible.

Further, as described above, it is possible to supply electric energy to surrounding loads without incorporating a load in the imitation plant. There is no limitation on the type of load, and it can be used, for example, for lighting equipment, safety signs, advertising panels, driving electric motors, and the like. For example, an imitation plant can be installed in a garden to light a garden light, drive a fountain or a water circulation pump in a pond, and the like. In any case, an imitation plant type photovoltaic power generation system that matches the landscape can be obtained by considering the configuration of the imitation plant.
