Can be used for power generation, and power generation efficiency is high.

  With reference to FIG. 2, a solar power generation apparatus including a plurality of cylindrical solar cells described in FIG. 1 will be described. FIG. 2A is a schematic perspective view of the photovoltaic power generation apparatus, and FIG. 2B is an enlarged lateral side view of the photovoltaic power generation apparatus.

  With reference to these drawings, the solar power generation device 10 includes a plurality of cylindrical solar cells 11, and the plurality of cylindrical solar cells 11 are formed in a plane by a pair of opposed L-shaped frame bodies 12. The arrays are held substantially parallel to each other. The frame body 12 is L-shaped with a vertical frame portion 12a and a horizontal frame portion 12b. In the illustrated example, the frame bodies 12 are shown as a pair opposed to each other for convenience of explanation, but the cylindrical solar cells are arranged and held in a quadrilateral shape as a whole, including a pair of frames opposed in a direction orthogonal to the frame body 12. May be.

  A plurality of leg portions 13 are attached to the frame body 12 at equal intervals. The number, form, and the like of the leg portions 13 can be determined according to the number of arrayed cylindrical solar cells, the weight, and the like.

  A power extraction electrode 12b is provided on the inner surface of the vertical frame portion 12a of the pair of opposed frame bodies 12. The power extraction electrode 12 b is provided in a strip shape along the arrangement direction of the cylindrical solar cells 11. The power extraction electrode 12 b is in contact with the electrodes 11 a protruding from both ends of the cylindrical solar cell 11. By this contact, the output power of the cylindrical solar cell 11 is extracted to the power extraction electrode 25b. Each cylindrical solar cell 11 is connected in parallel to each other by having both end electrodes 11a in common contact with the power extraction electrode 12b. A power cable 14 is attached to each frame 12. One end of the power cable 14 is connected to the power extraction electrode 12b by a structure not shown.

  A plurality of installation portions (not shown) for the cylindrical solar cell 11 are formed on the bottom surface of the horizontal frame portion 12 b of the frame body 12. This installation part is formed in accordance with the arrangement interval of the cylindrical solar cells 11. Even if a cylindrical solar cell is arranged in all the installation parts, or a cylindrical solar cell is arranged in every other installation part or every other installation part, the arrangement number of the cylindrical solar cells can be selected. Good.

  The solar power generation device 10 sets the number of arrangements of the cylindrical solar cells 11 to the installation portion of the frame 12 according to the installation environment, adjusts the arrangement interval of the cylindrical solar cells 11, or It is preferable that the installation height of the cylindrical solar cell can be adjusted by adjusting the leg length of the portion 13. Although not shown, the leg portion 13 capable of adjusting the leg length can be configured by, for example, inserting the inner cylinder slidably into the outer cylinder and fixing both the cylinders with a connecting bolt. . The photovoltaic power generation apparatus 10 may be configured such that the inclination can be adjusted with a maximum inclination of about 30 degrees with respect to the horizontal plane so that the entire array surface of the cylindrical solar cells 11 can be directed to sunlight.

  Next, with reference to FIG. 3, the installation method of a cylindrical solar cell is demonstrated based on the sunlight utilization system using this installation method. The solar light utilization system 15 supplies the output of the solar power generation device 16 to the controller 18 via the power cable 17. The place where the solar power generation device 16 is installed is above the paddy field 19. The plurality of cylindrical solar cells 11 in the solar power generation device 16 are arranged in parallel with each other at a predetermined height from the paddy field 19 at a predetermined interval.

  The controller 18 operates the water supply pump 20 based on the output generated by each cylindrical solar cell 11 in the solar power generation device 16 and controls water supply from the water supply pipe 21 to the paddy field 19. A water level sensor (not shown) is arranged in the paddy field 19, and the controller 18 operates the water supply pump 20 to supply water based on the output of the water level sensor indicating the water level of the paddy field 19 when the water level is below a certain level. When the water level is higher than a certain level, the operation of the feed water pump 20 is stopped.

  In such a sunlight utilization system 15, the solar power generation device 16 includes a frame body 16a, a plurality of cylindrical solar cells 16b arranged in the frame body 16a, and leg portions 16c.

  In the installation method of the present embodiment, a plurality of cylindrical solar cells 16b are arranged in the frame body 16a, and are installed substantially horizontally at a predetermined height above the paddy field 19 as described above. The number of arrays that can generate electric power necessary for the operation of electrical equipment such as the water supply pump 20 at an array interval at which the sunlight 22 required for the growth of 23 can irradiate the paddy field 19 from between the plurality of cylindrical solar cells 16b. Thus, the installation of each cylindrical solar cell 16b is adjusted.

  Although the cylindrical solar cells 16b are arranged in a horizontal plane in FIG. 3, they may be installed with a desired inclination angle, for example, a maximum of 30 degrees with respect to the horizontal plane. For example, it is preferable that the cylindrical solar cell 16b can be installed with a maximum inclination of 30 degrees southward with respect to the horizontal plane. As this installation method, for example, the leg angle of the pair of leg portions 16c opposed on the south side may be adjusted to be relatively shorter than that of the pair of leg portions 16c opposed on the opposite side to adjust the inclination angle.

  In FIG. 3, the cylindrical solar cell 16 b is installed so as to cover the entire upper part of the paddy field 19, but is arranged so as to cover a part of the upper part of the paddy field 19 according to the required electric power, the area of the paddy field 19, and the like. Also good.

  Regarding the adjustment of the arrangement interval of the cylindrical solar cells 16b, for example, the power extraction electrodes formed on the vertical frame portions of the pair of frame bodies 16a are brought into contact with both end electrodes of each cylindrical solar cell 16b, while On the horizontal frame portion, the cylindrical solar cells 16b are slid in accordance with the arrangement interval to be adjusted, and fixed at a required position, thereby adjusting the arrangement intervals of the cylindrical solar cells 16b. Alternatively, the arrangement interval may be adjusted by increasing or decreasing the number of arrangements of the cylindrical solar cells 16b.

  By this adjustment, the sunlight 22 can irradiate the paddy field 19 from the gap between the arrangements of the cylindrical solar cells 16b, and the paddy rice field 19 can be grown and cultivated. Further, the leg 16c may be expanded and contracted in the height direction so that the arrangement height of the cylindrical solar cell 16b can be adjusted.

  In the installation method according to this embodiment, a plurality of cylindrical solar cells 16b are arranged above a place where sunlight irradiation is required, such as a paddy field or a field, and at least sunlight is emitted from between each cylindrical solar cell 16b to the place. Since the arrangement interval of the cylindrical solar cells 16b can be adjusted so that only the required amount can be irradiated, even if the cylindrical solar cells 16b are arranged above the place, the sunlight can be irradiated to such places. Unlike the flat panel photovoltaic power generation panel, it is not necessary to secure a place for installing the cylindrical solar cell 16b in addition to the above place, and the installation cost can be significantly reduced.

  In this embodiment, the farmland is a paddy field, but is not limited to a paddy field, and can be applied to all farmland including the paddy field.

  With reference to FIG. 4, another solar light utilization system using the solar power generation device will be described. This solar light utilization system is applied to a cultivation house.

  The controller 30 controls the water supply equipment 28 and the air-conditioning equipment 29 based on the output from the water level, temperature, and humidity sensors (not shown) in the cultivation tank 27 to manage the crops in the cultivation tank 27. The crop is not particularly limited, but may be, for example, paddy rice. When a paddy field is soaked with seawater, for example, the paddy field becomes so-called salt damage, which makes it impossible to cultivate paddy rice due to salt in the seawater. Since the solar light utilization system of the embodiment of FIG. 4 can cultivate paddy rice in the cultivation tank 27, when the paddy field is damaged by salt damage, the paddy rice cultivation in the paddy field is switched to paddy rice cultivation in the cultivation tank 27. It is a particularly effective system. In the cultivation tank 27, hydroponics can also be performed. Of course, in the case of paddy rice cultivation in the cultivation tank 27, the cultivation house 25 is unnecessary.

  In the solar light utilization system 24, the solar power generation device 26 includes a frame body 26a and a plurality of cylindrical solar cells 26b arranged in the frame body 26a. The legs are not shown in the figure, but pillars not shown in the cultivation house 25 may be used instead. And although the cylindrical solar cell 26b is installed above the cultivation tank 27 which needs irradiation of sunlight, sunlight 31 irradiates the cultivation tank 27 from the clearance gap between arrangement | positioning of the cylindrical solar cell 26b. It is possible to cultivate various crops in the cultivation house 25.

  In the installation method according to this embodiment, a plurality of cylindrical solar cells 26b are arranged above the cultivation tank 27 of the cultivation house 25 so that the cultivation tank 27 can be irradiated with sunlight from between the cylindrical solar cells 26b. Since the arrangement interval of the solar cells 26b is adjusted, the cultivation tank 27 can be irradiated with sunlight, and the cylindrical solar cells 26b are installed in the cultivation house 25 without disturbing the cultivation in the cultivation tank 27. Since the space can be secured, the installation cost can be reduced.

  Although the installation method of the embodiment is applied to farmland or cultivation house, any installation form may be used as long as the cylindrical solar cell is installed.

  With reference to FIG. 5, still another sunlight utilization system using the photovoltaic power generation apparatus will be described. In this solar light utilization system 32, it is applied to the cultivation house like that of FIG. The solar light utilization system 32 illustrated in FIG. 5 has a solar power generation device 34 installed outside the cultivation house 33 and directly above the house 33. The solar power generation device 34 includes a frame body 34a and a plurality of cylindrical solar cells 34b arranged in the frame body 34a. The legs are not shown. 35 is a cultivation tank, 36 is a water supply facility, 37 is an air conditioning facility, and 38 is a controller. In this solar light utilization system 32, since the solar power generation device 34 is disposed outside the cultivation house 33, the space in the cultivation house 33 can be widely utilized.

  Referring to FIG. 6, another solar power utilization system using the above solar power generation device will be described. This solar power generation device 41 is used as a sunshade in a school yard, nursery school, kindergarten garden, park, etc. Install in the place 40 to use. In this solar power generation device 41, a certain number of cylindrical solar cells 41b are arranged substantially in parallel with the frame body 41a to form one set of solar cell modules, which are assembled in the required number of sets according to the size of the place 40. It is a thing. The solar power generation apparatus 41 is installed at a place 40 where a plurality of leg portions 41c are attached to a frame body 41a and a bench 42 for rest is provided. This solar power generation device 41 is installed in a awning place 40 such as a school yard, a nursery school, a kindergarten garden, etc. to cover the power required by unillustrated electrical equipment such as a school, a nursery school, and a kindergarten. It can be done.

  By making the arrangement interval of the plurality of cylindrical solar cells 41b in the solar power generation device 41 wider and narrower, the area that can be shaded at the place 40 by the cylindrical solar cells 41b, that is, the amount of sunlight blocked. If the place 40 is a park, the place 40 can be shaded by a plurality of cylindrical solar cells 41b and can be rested by sitting on a bench 42 installed at the place 40. Also good. And since the electric power generated by these solar power generation devices 41 is used for the power of the night illumination lamp 43 installed in the vicinity of those places, the generated power of the solar power generation device 41 is diverted in the daytime by the management facility 44. The power that has been discharged may be used by the night illumination lamp 43 at night.
