Description

  The present invention relates to a photovoltaic power generation unit and a photovoltaic power generation system installed on the ground.

  Generally, when the inclination angle of a solar cell module is set at the optimum incident angle of sunlight, the power generation efficiency of the module alone is the best. For this reason, when installing a solar cell module in horizontal surfaces, such as a flat roof and the ground, it is preferable to incline and arrange a several solar cell module toward the same direction.

  However, in such an arrangement, when the solar cell modules are arranged close to each other, the shadows of the solar cell modules are not only in the morning and evening when the sun tilts, but also in the daytime when the sun is high and the solar radiation intensity is strong. Is inserted into a part of the light receiving surface of another solar cell module adjacent to, and the shaded portion does not generate power, resulting in a decrease in power generation efficiency.

  Thus, if each solar cell module is arrange | positioned mutually spaced apart, the shadow of a solar cell module will not be inserted in the light-receiving surface of another solar cell module, and it does not need to reduce the power generation efficiency of a solar cell module.

  However, in such an arrangement, an installation area required for installing a predetermined number of solar cell modules is increased, and an empty space that does not contribute to power generation is widened. Therefore, in Patent Document 3, the solar cell is configured by using a solar cell panel main body and a mount on which the solar cell panel main body is arranged as a saw-like slope, and the reflected light reflected by the first solar cell unit. Is going to be absorbed by the second solar cell section to prevent a decrease in power generation efficiency.

  On the other hand, if a plurality of solar cell modules are horizontally installed and arranged, none of the solar cell modules are hidden behind the shadow. However, in this case, rainwater or the like tends to stay on the light receiving surface of the solar cell module, resulting in a decrease in power generation efficiency due to adhesion of dirt on the light receiving surface.

  For this reason, in Patent Document 4, on the premise that a plurality of solar cell modules are arranged next to each other horizontally, the solar cell module itself is folded in a mountain, the light receiving surface of the solar cell module is inclined, and the solar cell It prevents rainwater and the like from staying on the light receiving surface of the module to prevent a decrease in power generation efficiency.

  Or in patent document 5, the 1st solar cell panel which inclines upward toward the positive direction of a 1st axis | shaft, and the 2nd solar cell panel which inclines downward toward the positive direction of a 1st axis | shaft. And a solar power generation apparatus in which a first solar cell panel and a plurality of second solar cell panels are alternately arranged adjacent to each other in the direction of the first axis is disclosed. It is disclosed that it is 5 degrees.

  Alternatively, Patent Document 6 includes a plurality of first solar cell panels that are inclined upward at an inclination angle of 3 degrees or more and less than 5 degrees, and a plurality of second solar cell panels that are inclined upward at an inclination angle of 3 degrees or more and less than 5 degrees. A solar power generation device that is alternately arranged adjacent to each other is disclosed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

  First, a schematic configuration of a photovoltaic power generation unit according to the first embodiment of the present invention will be described with reference to FIG. In FIG. 1, two photovoltaic power generation units 10a and 10b are arranged on the ground surface. One photovoltaic power generation unit 10a is fixed so that a gantry support portion 106 acting as a support portion installed so that the upper end thereof has a predetermined height from the ground surface extends in a direction perpendicular to the ground surface. Yes. When the gantry support unit 106 is arranged so that the light receiving surfaces of the plurality of solar cell modules 101 and 102 are inclined at predetermined angles in different directions to form a mountain shape, the ends of the solar cell modules 101 and 102 are connected to each other. Are arranged on a concrete pile foundation (not shown) at a predetermined interval so that the ridges are formed, or the tips are buried deep in the ground.

  At the upper ends of the gantry support portions 106, 106, a light receiving surface is supported at the center portion at the upper end of the support portion, and the first and second solar cell modules are inclined in different directions on both sides with the center portion as a boundary. A pair of base rails 108, 108 acting as a pedestal for holding them so as to have them are stretched substantially parallel to the ground surface. A horizontal beam 103a is disposed at the center of each of the base rails 108 and 108 via a gantry support unit 106, and a horizontal beam 103b is disposed at both ends so as to be orthogonal to the base rail 108. The horizontal crosspieces 103a and 103b acting as crosspiece members act as holding members and crosspiece members. The solar cell modules 101 and 102 are arranged so as to straddle the central horizontal beam 103a and the horizontal beam 103b at both ends. The gantry support unit 106, the base rail 108, and the horizontal rails 103a and 103b constitute a gantry unit.

  More specifically, the solar cell module 101 that forms the first light-receiving surface and the solar cell module 102 that forms the second light-receiving surface so that the horizontal beam 103a becomes an inclined top portion of the horizontal beam 103a and 103b. The solar cell modules 101 and 102 each form a mountain-shaped light receiving surface. That is, the height of one end and the other end of the solar cell modules 101 and 102 is varied by the horizontal rails 103a and 103b.

  The solar cell modules 101 and 102 are rectangular modules each having a short side frame and a long side frame, and the solar power generation units 10a and 10b are configured by combining three solar cell modules 101 and 102. The short side frame is arranged so that the long side frame is inclined with the short side frame facing the central horizontal rail 103a side. However, the long side frame may be arranged so that the long side frame is directed toward the central horizontal rail 103a and the short side frame is inclined. Moreover, you may arrange | position the solar cell module connected 3 each, and you may combine arbitrary numbers, without restricting a solar cell module to 3 each.

  The other solar power generation unit 10b is configured in the same manner as the one solar power generation unit 10a. The photovoltaic power generation units 10a and 10b have gaps in which the intervals between the inclined lower ends are, for example, around 100 mm, and rainwater and the like are efficiently discharged from the gaps. That is, dirt such as dirt and dust is discharged to the ground by rainwater, and in the case of heavy rain, a puddle is generated at the lower end of the solar cell modules 101 and 102, and the light receiving surfaces of the solar cell modules 101 and 102 are contaminated. It is avoided that it becomes easy to adhere. In particular, when the solar cell modules 101 and 102 are installed on the ground by installing foundations or piles, the environment is easily affected by wind dust, so the solar cell modules 101 and 102 of the embodiment shown in FIG. The inclined lower end is preferably provided with a gap.

  The two solar power generation units 10a and 10b form a mountain-shaped light receiving surface on which the solar cell modules 101 and 102 are independent, respectively, but the solar cell module 102 of one solar power generation unit 10a and the other The solar cell module 101 of the photovoltaic power generation unit 10b forms a valley-shaped light receiving surface.

  More preferably, the angle formed by the mountain-shaped or valley-shaped light receiving surfaces formed by the adjacent solar cell modules 101 and 102 is set in a range of 160 degrees to 170 degrees. By setting the angle within this range, it is possible to generate power by receiving sunlight most efficiently with less time for shadowing relative to the sunshine hours.

  In consideration of the workability of removing the solar cell modules 101 and 102, it is preferable that the end portions of the horizontal rails 103a and 103b protrude appropriately from the base rail 108 to the outside.

  Moreover, it is preferable that the gantry support part 106 protrudes from the ground in the range of about 1 m to 2 m from the ground, and it is more preferable to set the height so that the operator can pass without bending down. Alternatively, it is sufficient that a work vehicle having a vehicle width that allows the solar battery modules 101 and 102 such as light trucks and golf carts to be placed on the vehicle, and the interval between the gantry support portions 106 is preferably separated from the width of the work vehicle. It is preferable that the distance between the gantry support portions 106 in the direction in which the solar cell modules 101 and 102 are arranged in a mountain shape or in the parallel direction of the base rail 108 is separated from the width of the work vehicle.

  FIG. 24 is a diagram for explaining an arrangement example in which a plurality of photovoltaic power generation units 130 are arranged.

  In this example, a pair of base rails 108 is fixed to the gantry support section 106 so as to form a mountain shape, and the light receiving surfaces of the two solar cell modules 101 and 102 are arranged thereon so as to form a mountain shape. A solar power generation unit 130 is configured, a plurality of these solar power generation units 130 are arranged, and base rails 108 of adjacent solar power generation units 130 are connected by a connecting member 119.

  By connecting a plurality of photovoltaic power generation units 130 in this way, they can be arranged in an array.

  FIG. 25A is a perspective view showing an example in which photovoltaic power generation units 130 having mountain-shaped light receiving surfaces are arranged in an array.

  In this example, a plurality of photovoltaic power generation units 130 shown in FIG. 24 are arranged in one direction on a flat land and in a direction orthogonal to the one direction. As described above, by arranging the plurality of photovoltaic power generation units 130 in an array, it is possible to effectively receive light from the sun and generate large power. Moreover, even if a large number of photovoltaic power generation units 130 are arranged in an array, each photovoltaic power generation unit 130 is supported by a gantry support unit 106 having a height of 1 m to 1.5 m, for example. Thereby, since an operator can work while standing, maintenance inspection becomes easy.

  FIG. 25B is a perspective view showing another example in which the photovoltaic power generation units 130 having mountain-shaped light receiving surfaces of the present invention are arranged in an array.

  In this example, a plurality of photovoltaic power generation units 130 are arranged on an upper horizontal land, a lower horizontal land, and an inclined land between them. Even in such a configuration, a large amount of power can be generated by effectively utilizing the land and arranging a plurality of photovoltaic power generation units 130 in an array.

  FIG. 26A is a perspective view showing an example in which photovoltaic power generation units 131 having valley-shaped light receiving surfaces are arranged in an array.

  FIG. 25A and FIG. 25B arrange the photovoltaic power generation units 130 having mountain-shaped light receiving surfaces in an array, whereas FIG. 26A shows a plurality of photovoltaic power generation units 131 having valley-shaped light receiving surfaces arranged on a flat land. Are arranged in an array in one direction and in a direction perpendicular to the one direction. Also in this example, since each solar power generation unit 131 does not block light from the sun by other units, it can receive sunlight effectively and can generate large power.

  FIG. 26B is a perspective view showing still another example of the photovoltaic power generation unit of the present invention.

  In this example, a plurality of photovoltaic power generation units 131 having valley-shaped light receiving surfaces are arranged on the upper horizontal land and the lower horizontal land, respectively, and a mountain-shaped land is formed on the inclined land between the upper and lower stages. A plurality of photovoltaic power generation units 130 having a light receiving surface are arranged. In the example shown in FIG. 26B, half the number of photovoltaic power generation units 130 are arranged on the inclined surface with respect to the photovoltaic power generation units 131 arranged in the upper and lower stages. However, the number of photovoltaic power generation units 130 to be arranged can be arbitrarily selected.

  A solar power generation system can be constructed using such a solar power generation unit, for example, a plurality of solar power generation units, a power line that collects generated power from the solar power generation unit, and a connection box that bundles a plurality of power lines The solar power generation system is constructed by including a power conversion device that converts the DC power collected in the connection box into AC power, and a power receiving and transformation facility for transmitting the power output from the power conversion device to the transmission line. The

  27A and 27B are a plan view and a side view showing an actual arrangement example of the photovoltaic power generation unit of the present invention, and FIGS. 28A and 28B are conventional photovoltaic power generations shown for comparison with the present invention. It is the top view and side view which show the example of arrangement | positioning of a unit.

The solar power generation unit 131 shown in FIG. 27A has a valley-shaped light receiving surface, and the solar cell modules 101 and 102 each have a power generation capacity of 240 W, for example, and have a spacing d of 100 mm at an installation angle of 10 degrees. They are spaced apart. When 6,006 solar cell modules 101 and 102 were arranged on land with a site area of about 15,450 m ² , the arrangement area was about 10,410 m ² and a power generation capacity of about 1,441 kW could be obtained.

On the other hand, as shown in FIG. 28B, when the solar power generation unit 132 in which the solar cell modules 101 and 102 face the same direction at an installation angle of 10 degrees is disposed on the site having the same area as that in FIG. Only 4,480 modules 101 and 102 could be arranged, and the installation area, which is the module installation range including the inter-array space, was about 11,000 m ² , and only a power generation capacity of about 1,075 kW was obtained. In this case, the gap A was 400 mm and the gap B was 150 mm apart.

  Therefore, when the same solar cell modules 101 and 102 are arranged on the same area, the photovoltaic power generation unit of the present invention shown in FIG. 27A can increase the power generation capacity of about 360 kW.

  Table 1 shown in FIG. 29 shows an example of comparison of various data of the photovoltaic power generation unit of the present invention having the arrangement configuration shown in FIG. 27A and the conventional photovoltaic power generation unit having the arrangement configuration shown in FIG. 28A.

(A) shows the rated output capacity (kW) of the photovoltaic power generation unit, (b) shows the annual power generation amount (kW) of the photovoltaic power generation unit when the installation location is a south-facing crystalline solar cell module in Tokyo. (C) is the module installation range (m ² ) that does not include the inter-array space, (d) is the module installation range (m ² ) that includes the inter-array space that is the maintenance space, and (e) is the maintenance space. And the area (m ² ) of the photovoltaic power generation unit including the outer road (width 10 m). The solar cell module capacity per unit area and the annual power generation amount are more in the embodiment of the present application shown in FIG.

  Therefore, a solar power generation unit using a solar cell module having the same capacity can be installed with a smaller installation area than before, and the surplus land can be effectively used for other purposes such as fields, parks, and tennis courts.

  In the above embodiment, an example in which the gantry support unit 106 is installed in a substantially vertical direction with respect to the ground has been described. However, when the ground is inclined, the gantry support unit 106 is substantially vertical. It is preferable to install in the direction. Further, when the light receiving surfaces of the plurality of solar cell modules 101 and 102 are arranged so as to be inclined at a predetermined angle in different directions to form a mountain shape or a valley shape, The inclination angle may be different with respect to the horizontal plane.

  For example, the photovoltaic power generation unit 131 shown in FIG. 27C has a valley-shaped light receiving surface, and the inclination angle of the light receiving surface of the photovoltaic power generation unit 101 is the ground surface on the ground inclined upward by about 5 degrees. In this embodiment, the light receiving surface of the solar cell module 102 is inclined about 5 degrees with respect to the horizontal plane in the direction opposite to the water flow direction of the ground surface. For example, when installed in the northern hemisphere, the amount of power generation per unit area increases when the water flow direction on the ground surface is on the south side.

  Further, when the light receiving surfaces of the plurality of solar cell modules 101 and 102 are arranged so as to be inclined in different directions at a predetermined different angle to form a mountain shape or a valley shape, the light receiving surfaces of the solar cell modules 101 and 102 May be different from each other with respect to the horizontal plane.

  For example, the photovoltaic power generation unit 131 shown in FIG. 27D has a valley-shaped light receiving surface, and on the ground where the ground surface rises to the right and inclines about 5 degrees, the inclination angle of the light receiving surface of the solar cell module 101 is It is assumed that the water flow direction of the ground surface is about 10 degrees with respect to the horizontal plane, and the inclination angle of the light receiving surface of the solar cell module 102 is inclined about 5 degrees with respect to the horizontal plane in the direction opposite to the water flow direction of the ground surface. For example, when installed in the northern hemisphere, the amount of power generation per unit area increases when the water flow direction on the ground surface is on the south side.

  For example, the photovoltaic power generation unit 131 shown in FIG. 27E has a valley-shaped light receiving surface, and when the ground surface is substantially horizontal, the inclination angle of the light receiving surface of the solar cell module 101 is about the ground surface. The inclination angle of the light receiving surface of the solar cell module 102 is 10 degrees with respect to the ground surface. For example, when installed in the northern hemisphere, the amount of power generation per unit area increases when the solar cell module 101 faces the south side.
