  Next, an embodiment of a method for assembling a cable suspension type aerial solar power generation facility according to the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic side view of a cable-suspended aerial photovoltaic power generator installed on the ground (viewed from the Y direction perpendicular to the paper surface), and (a) shows the same height of the main strut and the intermediate strut. (B) is a case where only the intermediate strut located in the center is the same as the height of the main strut, and (c) is a case where the height of the intermediate strut is lower than that of the main strut. 2 is a schematic plan view showing the cable-suspended aerial solar power generation apparatus shown in FIG. 1, FIG. 3 is a partial side view showing the intermediate strut, and FIG. 4 is a partial front view showing the intermediate strut.

  First, the suspension structure portion, work site, intermediate strut, and saddle portion in the present invention will be described.

<Suspension structure part>
The suspension structure portion includes a plurality of main struts M installed separately from each other and a cable C suspended between the plurality of main struts M (see FIGS. 1 and 2). Each of the plurality of photovoltaic power generation panels P (not shown) installed on the plurality of cables C is configured such that the longitudinal direction thereof is the Y direction, and the panel surface is configured by the X direction and the Y direction. It is constructed so as to be substantially parallel to the flat surface (XY plane). As shown in FIGS. 1 and 2, both ends of the cable C are fixed to the anchor member A via the main column M, but the cable C may be directly fixed to the main column M.

<Work site>
A typical work site S is a workbench provided with wheels and a braking mechanism for the wheels. The movement of the work table in a state where the braking mechanism is not operated may be self-propelled by rotating a wheel by a driving device, or may be movement by human power. The work table may include an elevating device that allows the work main surface to be raised and lowered. If the work main surface can be raised and lowered, the worker can receive the cable C and the photovoltaic power generation panel P, attach the photovoltaic power generation panel P to the cable, send out the cable C to which the photovoltaic power generation panel P is attached, and the like. The height of the work main surface suitable for each work can be set (FIGS. 5 and 6).

<Intermediate strut>
The intermediate strut I that supports the bending of the cable C is installed between the main struts M (see FIGS. 1 and 2). As shown in the partial side view of FIG. 3 and the partial front view of FIG. It consists of saddle part 2. The number of intermediate struts I may be one, or two or more. As shown in FIG. 1, diagonal materials are provided on both sides of the intermediate support column I, but diagonal materials are not always necessary.

<Saddle Club>
As shown in FIGS. 3 and 4, the saddle portion 2 reduces the bending without fixing the cable C and prevents the intermediate post I from falling off, and the straight pipe member constituting the intermediate post I 1 is attached to the top. That is, a plate-like or disk-like mounting base 3 is fixed to the upper end portion of the straight pipe member 1 by means such as welding, and is integrated with the straight pipe member 1. A recess 3 a is formed on the upper surface of the mounting table 3, and a protruding portion 2 a formed on the lower surface of the saddle portion 2 is fitted in the recess 3 a. A groove 2b extending in the X direction is formed in the upper portion of the saddle portion 2, and the cable C on which tension is applied is accommodated in the groove 2b. At this time, since the movement of the cable C in the Y direction is restricted by the wall surface of the groove 2b, the cable C is prevented from dropping from the saddle portion 2 and thus from the top of the intermediate column I. Since the height of the protruding portion 2a is the same or slightly larger than the depth of the recess 3a, the bottom surface of the saddle portion 2 is arranged so as to be in contact with the top surface of the mounting table 3 without leaving a gap or to leave a slight gap. Is done. As a result, the saddle portion 2 can change its posture with respect to the straight pipe member 1 constituting the intermediate column I. A similar saddle portion 2 is also attached to the upper end portion of the main column M.

  The material of the saddle portion 2 is selected from SCW490, SS400, SM400A, and the like. SS400 is preferable because it is easy to manufacture and economical. SM400A is preferred when the photovoltaic panel is relatively large and there are many locations that require welding. In some cases, it is preferable to adopt SCW490 (cast steel product) when the weight supported by one intermediate column becomes larger.

  One saddle portion 2 provided in one intermediate strut I may be one or two or more. There may be one cable C in contact with one saddle portion 2 or two or more cables C. The number of intermediate struts I having one saddle portion 2 may be one or two or more. When one intermediate strut I supports the bending of the plurality of cables C, a plurality of saddle portions 2 that contact each of the plurality of cables C may be provided on the intermediate strut I, One saddle portion 2 common to the plurality of cables C (or in contact with the plurality of cables C at the same time) may be provided on the intermediate strut I, and is in contact with each part of the plurality of cables C. One or two or more saddle portions 2 may be provided, and one or two or more saddle portions common to the remaining portion (or in contact with the plurality of cables C at the same time) may be provided.

  When the distance between the main struts M in the axial (longitudinal) direction (X direction) of the cable C is short, the cable suspension type aerial photovoltaic power generator does not require the intermediate strut I, but when the distance is long Requires an intermediate column I for supporting the weight of the cable C, the frame F installed on the cable C, and the photovoltaic panel P attached to the frame F.

  In the following description, it is assumed that the number of intermediate struts I in the X direction is 1 or more. However, the present invention does not exclude the case where there is no intermediate strut I.

  As shown in FIGS. 1 and 2, the cable suspended aerial photovoltaic power generation device U [ij] includes a pair of main struts M (2i-1) j and M (2i-1) (j +) separated in the X direction. 1) and intermediate struts I (2i-1) jk, I (2i-1) j (k + 1), I (2i-1) j (k + 2) arranged between the pair of main struts ) And a pair of main struts M (2i) j and M (2i) (j + 1) separated in the X direction and between the pair of main struts. A pair of cables C comprising a second cable Cb suspended from the intermediate struts I (2i) jk, I (2i) j (k + 1), I (2i) j (k + 2) A suspension structure including a workpiece W (Wa, Wb) including a frame F installed on a pair of cables C and a photovoltaic power generation panel P attached to the frame F is provided. Note that i and j are integers of 1 or more, and m and n are the upper limit values.

  Both ends of the first cable Ca constituting the workpiece W (Wa) are fixed to the ground G by anchor members A (2i-1) L and A (2i-1) R, and the workpiece W (Wb) The two ends of the second cable Cb constituting the are fixed to the ground G by anchor members A (2i) L and A (2i) R. A tension is applied to a pair of cables (first cable Ca and second cable Cb) C suspended between a pair of main struts separated in the X direction and intermediate struts arranged between the main struts. It is. Therefore, the pair of cables C is arranged at a position away from the position in contact with the ground G, and as a result, the solar power generation panel P attached to the frame F installed on the pair of cables C is arranged in the air. Is done.

  In FIGS. 1 and 2, three intermediate struts are drawn between a pair of main struts in the X direction (total of six), but one per pair of main struts in the X direction (two in total). However, it may be two (a total of four) or four (a total of eight) or more.

  As shown in FIGS. 1 (a) to 1 (c), the height of the column (the height of the cable support position by the saddle portion) is the same as that of the main column and the intermediate column as shown in (a). As shown in (b), only the intermediate strut located at the center between the main struts in the X direction is the same as the height of the main strut, and the other intermediate struts may be lower than the main strut, As shown in (c), the height of the intermediate strut may be lower than that of the main strut. Of course, modes other than FIGS. 1A to 1C may be used.

  Further, the range of the cable suspension type aerial photovoltaic power generator U [ij] shown in FIG. 2 includes anchor members (A (2i-1) L and A (2i-1) R, A (2i) L and A ( 2i) An anchor member may be included when defining the range that does not include R).

  FIG. 5 is an explanatory diagram of an assembling method of the cable-suspended air solar power generation device U [11]. The description based on FIG. 5 also applies to the more general case where either i or j is not 1.

  An example (first example) of the assembling method includes the following steps.

  <Step 1> The work site S is set up at a position adjacent to the installation location of the cable suspended aerial photovoltaic power generation device U [11] in the X direction.

  <Step 2> A plurality of main columns M11, M12, M21, and M22 are installed.

  <Step 3> The cable C, the frame F, the photovoltaic power generation panel P, and other members and tools necessary for work are supplied to the work site S.

  <Step 4> At the work site S, an on-site worker (not shown) creates the workpiece W, and connects the first cable Ca constituting the workpiece W from the main column M12 side to the main column M11 side. The second cable Cb is sent out from the main column M22 side to the main column M21 side. Thereby, the workpiece W (Wa, Wb) is sent out together with the pair of cables C toward the side opposite to the work site S.

  The workpiece W is configured by installing a frame F on a pair of cables C (Ca, Cb) and attaching a photovoltaic power generation panel P to the frame F. In the following, the workpiece W viewed with the first cable Ca as a reference is denoted as Wa, and the workpiece W viewed with the first cable Cb as a reference is denoted as Wb.

  <Step 5> The pair of cables C sent out from the work site S are suspended between the main columns M11 and M12 and between the main columns M21 and M22. If necessary, intermediate struts I1k and I2k are arranged between the main struts M11 and M12 and between the main struts M21 and M22, and the first cable Ca and the second cable Cb are suspended on the intermediate struts. As a result, the workpiece W (Wa, Wb) is suspended between the main columns M11 and M12 and between the main columns M21 and M22.

  <Step 6> The following (1) or (2) is performed to construct a suspended structure.

  (1) One end of the first cable Ca is fixed by the anchor member A1R (not shown) on the work site S side (the side where the main columns M12 and M22 are located), and the second is fixed by the anchor member A2R (not shown). One end of the cable Cb is fixed, and the first cable Ca and the second cable Cb are pulled in the −X direction on the opposite side of the work site S (the side where the main columns M11 and M21 are present). As a result, the pair of cables C (Ca, Cb) are arranged at positions away from the ground G between the main struts, between the main struts and the intermediate struts, and between the intermediate struts, and are installed on the pair of cables C. The solar power generation panel P attached to the frame F is disposed in the air. While maintaining the state in which this tension is applied, one end of the first cable Ca is fixed by the anchor member A1L (not shown) on the opposite side of the work site S, and the first end is fixed by the anchor member A2L (not shown). One end of the second cable Cb is fixed.

  (2) One end of the first cable Ca is fixed by the anchor member A1L on the side opposite to the work site S side, and one end of the second cable Cb is fixed by the anchor member A2L. Pull the cable Ca and the second cable Cb in the + X direction. As a result, the pair of cables C (Ca, Cb) are arranged at positions away from the ground G between the main struts, between the main struts and the intermediate struts, and between the intermediate struts, and are installed on the pair of cables C. The solar power generation panel P attached to the frame F is disposed in the air. While maintaining the state where this tension is applied, one end of the first cable Ca is fixed by the anchor member A1R on the work site S side, and one end of the second cable Cb is fixed by the anchor member A2R.

  <Step 7> If necessary, adjust the hanging state of the pair of cables C between the main struts, between the main struts and the intermediate struts, and between the intermediate struts, and make the weight supported by the main struts and the intermediate struts appropriate. .

  In the above first example, the execution order of step 1 and step 2 may be reversed or may be executed simultaneously.

  In step 1, the work site S may be installed on the main column M11, M21 side. In that case, in step 4, the first cable Ca constituting the workpiece W is moved from the main column M11 side to the main column M12 side, and the second cable Cb is transferred from the main column M21 side to the main column M22 side. The work W (Wa, Wb) is suspended between the main struts M11 and M12 and between the main struts M21 and M22. The contents of Step 6 are as follows: (a) The work site S side is the side where the main columns M11 and M21 are located, the anchor member A1L is the anchor member on the work site S side, and the opposite side of the work site S is the main column M12 and M22 are on the side, the anchor member A1R becomes the anchor member on the opposite side of the work site S, and (b) When tension is applied to the pair of cables C, it is necessary to pull in the + X direction. It will be read as appropriate after consideration.

  The method of supplying the cable C, the frame F, etc. to the work site S in the process 3 is based on the human power between the on-site worker who works at the work site S and the off-site worker who works outside the work site S. It may be work (for example, handing), supply by non-human power using a dedicated device, or supply by partial human power or the remaining non-human power. In some cases, tools and the like need only be supplied once.

  For sending out the workpiece W from the work site S in the process 4, for example, another cable (traction auxiliary cable) is attached to a pair of cables C (Ca, Cb) constituting the workpiece W, and the traction auxiliary cable is mainly used. This can be realized by pulling from the column M12, M22 side to the main column M11, M21 side. At that time, if another cable (lifting auxiliary cable) is attached to the pair of cables C at intervals along the X direction, and the pair of cables C is pulled upward, the pair of cables C is pulled up. The workpiece W (Wa, Wb) can be prevented from coming into contact with the ground G or other obstacles. Even when the cable C is pulled up, it is preferable to attach a cushioning material to the surface opposite to the light receiving surface of the photovoltaic panel P in order to reduce the adverse effects of contact with the ground G and other obstacles. When step 6 is completed, the traction auxiliary cable, the lifting auxiliary cable, and the cushioning material are no longer necessary, and are removed as necessary.

  In step 5, for example, by pulling up the lifting auxiliary cable or by pushing up the cable C with a special machine, the cable C is temporarily lifted to a suspended position of the main strut or the intermediate strut or a slightly higher position, and then the cable C is lifted. This can be realized by suspending the cable on each column by moving it slightly to a predetermined position and then lowering it.

  In step 6, after fixing one end of a pair of cables C with an anchor member, the pair of cables is pulled. (The purpose of pulling the pair of cables C is to place the workpiece W in the air. As long as the purpose can be achieved, the one end of the pair of cables C is fixed by the anchor member before pulling. In that case, the work W is placed in the air by temporarily fixing one end of the pair of cables C after being temporarily fixed by another means, and then fixed by the anchor member. It may be.

  Step 7 is a step of performing fine adjustment so that the suspension structure is not forced. For example, if the main strut and the intermediate strut are provided with a mechanism for supporting the cables C (Ca, Cb) so as not to drop off by the saddle portions installed on the tops thereof, the step 7 includes the saddle portions. It includes making the balance and distribution of the tension acting on the cable C as uniform as possible by adjusting the posture and orientation.

  Another example (second example) of the method for assembling the cable-suspended air solar power generation device U [11] has the following steps.

  <Step 1> The work site S is set up at a position adjacent to the installation location of the cable suspended aerial photovoltaic power generation device U [11] in the X direction.

  <Step 2> A plurality of main columns M11, M12, M21, and M22 are installed.

  <Step 3> The cable C, the frame F, the photovoltaic power generation panel P, and other members and tools necessary for work are supplied to the work site S.

  <Process 3A> One end of the first cable Ca is fixed by the anchor member A1R (not shown) on the work site S side (the side where the main columns M12 and M22 are present), and the second is fixed by the anchor member A2R (not shown). One end of the cable Cb is fixed.

  <Step 4> At the work site S, an on-site worker (not shown) creates the workpiece W, and connects the first cable Ca constituting the workpiece W from the main column M12 side to the main column M11 side. The second cable Cb is sent out from the main column M22 side to the main column M21 side. Thereby, the workpiece W (Wa, Wb) is sent out together with the pair of cables C toward the side opposite to the work site S.

  <Step 5> The pair of cables C sent out from the work site S are suspended between the main columns M11 and M12 and between the main columns M21 and M22. If necessary, intermediate struts I1k and I2k are arranged between the main struts M11 and M12 and between the main struts M21 and M22, and the first cable Ca and the second cable Cb are suspended on the intermediate struts. As a result, the workpiece W (Wa, Wb) is suspended between the main columns M11 and M12 and between the main columns M21 and M22.

  <Step 6A> The following work is performed to construct a suspended structure.

  The first cable Ca and the second cable Cb are pulled in the −X direction on the opposite side of the work site S (the side where the main columns M11 and M21 are present). As a result, the pair of cables C (Ca, Cb) are arranged at positions away from the ground G between the main struts, between the main struts and the intermediate struts, and between the intermediate struts, and are installed on the pair of cables C. The solar power generation panel P attached to the frame F is disposed in the air. While maintaining the state in which this tension is applied, one end of the first cable Ca is fixed by the anchor member A1L (not shown) on the opposite side of the work site S, and the first end is fixed by the anchor member A2L (not shown). One end of the second cable Cb is fixed.

  <Step 7> If necessary, adjust the hanging state of the pair of cables C between the main struts, between the main struts and the intermediate struts, and between the intermediate struts, and make the weight supported by the main struts and the intermediate struts appropriate. .

  The major difference between the first example and the second example is that in the first example, the end of the cable is fixed after the workpiece W is sent out from the work site S, whereas in the second example, the workpiece W is One end of the cable is fixed before being sent out from the work site S. In the second example, when the workpiece W is sent out from the work site S, one end of the cable is already fixed. Therefore, when the cable C is sent out by pulling, the workpiece W is caused by the tension acting on the cable C. Is separated from the ground G. Therefore, there is an advantage that the workpiece W can be sent out while avoiding contact with the ground G or an obstacle. (In the case of the first example, the workpiece W is suspended on the support after the feeding is finished, so it is easy to collide with the ground G and other obstacles. Therefore, a buffer material or the like is used. To avoid contact)

  In said 2nd example, the description about the process 1, the process 2, the process 3, the process 5, and the process 7 is the same as the description in a 1st example.

  In step 1, the work site S may be installed on the main column M11, M21 side. In this case, in step 3A, one end of the first cable Ca is fixed by the anchor member A1L on the work site S side (the side where the main columns M11 and M21 are present), and one end of the second cable Cb is fixed by the anchor member A2L. It becomes a process to do. In step 4, the first cable Ca constituting the workpiece W is sent from the main column M11 side to the main column M12 side, and the second cable Cb is sent from the main column M21 side to the main column M22 side. It becomes. The contents of the process 6A are as follows: (a) The work site S side is the side where the main columns M11 and M21 are located, the opposite side of the work site S is the side where the main columns M12 and M22 are located, and the anchor member A1R is the opposite side of the work site S And (a) when applying tension to the pair of cables C, it is necessary to read them as appropriate in consideration of the necessity of pulling in the + X direction.

  As in the first example, the work W is sent out from the work site S in the process 4 by, for example, connecting the traction auxiliary cable attached to the pair of cables C (Ca, Cb) constituting the work W to the main column M12, This can be realized by pulling from the M22 side to the main column M11, M21 side. At that time, if the lifting auxiliary cable is attached to the pair of cables C at intervals along the X direction and the lifting auxiliary cable is pulled upward to pull up the pair of cables C, the workpiece W ( Wa, Wb) can be prevented from contacting the ground G or other obstacles. Even when the cable C is pulled up, it is preferable to attach a cushioning material to the surface opposite to the light receiving surface of the photovoltaic panel P in order to reduce the adverse effects of contact with the ground G and other obstacles. When step 6 is completed, the traction auxiliary cable, the lifting auxiliary cable, and the cushioning material are no longer necessary, and are removed as necessary.

  In step 3A, one end of the pair of cables C is fixed to the anchor member (A1R, A2R), and then in step 6A, the pair of cables C is pulled. (The purpose of pulling the pair of cables C is to place the workpiece W in the air. As long as the purpose can be achieved, the fixing of one end of the pair of cables C is fixing by an anchor member. In that case, after one end of the pair of cables C is temporarily fixed by another means, the workpiece W is placed in the air by pulling, and then fixed by the anchor member. Also good.

  Yet another example (third example) of the method for assembling the cable-suspended air solar power generation device U [11] has the following steps.

  <Step 1> The work site S is set up at a position adjacent to the installation location of the cable suspended aerial photovoltaic power generation device U [11] in the X direction.

  <Step 2A> The intermediate strut I1k is disposed between the main struts M11, M12, M21, M22 and the main struts M11, M12, and the intermediate strut I2k is disposed between the main struts M21, M22.

  <Step 3> The cable C, the frame F, the photovoltaic power generation panel P, and other members and tools necessary for work are supplied to the work site S.

  <Process 3A> One end of the first cable Ca is fixed by the anchor member A1R (not shown) on the work site S side (the side where the main columns M12 and M22 are present), and the second is fixed by the anchor member A2R (not shown). One end of the cable Cb is fixed.

  <Step 4> At the work site S, an on-site worker (not shown) creates the workpiece W, and connects the first cable Ca constituting the workpiece W from the main column M12 side to the main column M11 side. The second cable Cb is sent out from the main column M22 side to the main column M21 side. Thereby, the workpiece W (Wa, Wb) is sent out together with the pair of cables C toward the side opposite to the work site S.

  <Step 5A> A pair of cables C (Ca, Cb) sent from the work site S are suspended between the main struts M11 and M12 and the intermediate struts I1k, and between the main struts M21 and M22 and the intermediate struts I2k. As a result, the workpiece W (Wa, Wb) is suspended between the main columns M11 and M12 and the intermediate column I1k, and between the main columns M21 and M22 and the intermediate column I2k.

  <Step 6B> The following work is performed to construct a suspended structure.

  The first cable Ca and the second cable Cb are pulled in the −X direction on the opposite side of the work site S (the side where the main columns M11 and M21 are present). While maintaining the state where the tension is applied, one end of the first cable Ca is fixed by the anchor member A1L on the opposite side of the work site S, and one end of the second cable Cb is fixed by the anchor member A (2i) L. To fix.

  <Step 7> If necessary, adjust the hanging state of the pair of cables C between the main struts, between the main struts and the intermediate struts, and between the intermediate struts, and make the weight supported by the main struts and the intermediate struts appropriate. .

  The major difference between the second example and the third example is that in the second example, as in the first example, it is essential to install the main strut, but the intermediate strut is installed as necessary (first In the third example, it is indispensable to install both the main strut and the intermediate strut (see step 2A in the third example). .

  In the third example, the explanation in the second example is more than that in the second example, except that the number of support columns on which the pair of cables C (Ca, Cb) and therefore the workpiece W (Wa, Wb) are suspended is larger. This is generally true. (The first to third examples are literally examples, and the present invention is not limited to these examples.)

  Yet another example (fourth example) of the method for assembling the cable-suspended air solar power generation device U [11] has the following steps.

  <Process 1> The main support | pillar M and the intermediate | middle support | pillar I are installed in the installation planned place of a cable suspension type | formula aerial solar power generation device.

  <Step 2> The work site S is set up in the vicinity of the main column M or the intermediate column I.

  <Step 3> The cable C is sent from one main support M to the other main support M, and the height of the cable sag is maintained so that the cable C is a saddle of all the supports (main support M and intermediate support I). Temporarily fasten to part 2. The grip portion of the frame F is attached to the cable C at a predetermined interval in advance. The grip portion may be attached to the cable C by a bolt or the like in advance by the supplier of the cable C or may be attached on the work site S. The sag means the sag of the cable caused by the weight of the cable itself or various members related to it, and the sag is the sag of the cable, and usually the straight line connecting the ends of the cable and the cable. It is the value which measured the vertical distance between in the center part of a support | pillar.

  <Step 4> The frame F is fixed to the gripping portion on the work site S with bolts or the like while balancing the tension of the cable C without unevenness of the load applied to the cable C on both sides of the intermediate column I.

  <Step 5> At the same time, the photovoltaic power generation panel P is fixed to the frame F on the work site S with bolts or the like. Repeat this operation.

  According to the fourth example, by attaching the grip portion to the cable C in advance, the attachment efficiency of the frame F and the photovoltaic power generation panel P is improved.

  After assembling the cable suspension type aerial photovoltaic power generation device (structural unit) U [11] by the assembly method illustrated above, the work site S is set as X in the planned installation location of the structural unit U [21] adjacent in the Y direction. Move to an adjacent position in the direction and set up there. Then, the structural unit U [21] including at least a plurality of main columns M31, M32, M41, and M42 is assembled by the assembling method. Thereafter, the work site S is further moved to a position adjacent in the X direction of the planned installation location of the structural unit U [31] adjacent in the Y direction, and is set there. Then, the structural unit U [31] including at least a plurality of main columns M51, M52, M61, and M62 is assembled by the assembling method (see FIG. 6). Thereafter, the same operation is repeated until the structural unit U [m1] is assembled, and the assembly of the structural unit group in the column of j = 1 is finished.

  Next, the work site S is moved in the X direction by a distance substantially corresponding to one unit structure. That is, the work site S is moved to an adjacent position in the X direction of the planned installation location of the structural unit U [m2] and installed there. Then, the structural unit U [m2] is assembled by the assembling method. Thereafter, the work site S is further moved to a position adjacent in the X direction where the structural unit U [(m-1) 2] adjacent in the Y direction is to be installed, and is set there. Then, the structural unit U [(m-1) 2] is assembled by the assembling method. Thereafter, the same operation is repeated until the structural unit U [12] is assembled, and the assembly of the structural unit group in the column of j = 2 is completed (see FIG. 7).

  Each time the assembly of the structural unit group is completed, the work site S is moved in the X direction by a distance corresponding to one unit structure, thereby increasing the number of structural unit groups in an arbitrary column j by assembling. (See FIG. 8), finally, the assembly of the structural unit group of j = n columns is finished, and an arbitrary equipment unit PU [pq] composed of the structural units of M rows and N columns is assembled (FIG. 9). reference). Note that p and q are integers of 1 or more, and s and t are the upper limit values.

  By assembling the equipment unit PU [pq], a larger scale equipment can be configured (see FIGS. 10 and 11).

  Since the cable suspension type aerial photovoltaic power generation facility according to the present invention includes at least one cable suspension type aerial photovoltaic power generation apparatus, all of those shown in FIG. 2, FIG. 9, FIG. 10, and FIG. It corresponds to the cable suspension type aerial solar power generation equipment in this invention.

  The X direction and the Y direction do not have to be perpendicular to each other, and may be obliquely (non-perpendicular) to each other as shown in FIG.
