Positioning is performed so that the centers of the formed through holes 41 coincide with each other, the solar cell module 12 is placed on the upper flange 38, and the mounting screws 40 are inserted into the through holes 41 and the screw through holes 42. The both sides of the back surface of the solar cell module 12 can be mounted on the two unit fixing members 36 by engaging the nuts 46 with the mounting screws 40.

[0023] Then, anchor bolts 44 are previously installed on the upper surface of the first flange portion 22 and the upper surface of the inclined roof plate portion 21 at a pitch interval of the through holes 45 formed in the lower flange 43, respectively. The one side of the pair of unit fixing members 36 is fixed by passing the anchor bolts 44 through the through holes 45 of the pair of unit fixing members 36 to which 12 is fixed and engaging the nuts 46 with the anchor bolts 44. In the drainage ditch 34, the other end is the inclined roof plate part 21, that is, the unit fixing member 36 to be paired with one side facing the eave side of the inclined roof 11 and the other side facing the ridge side of the inclined roof 11 Can be grounded and fixed on 11 eaves.

[0024] On the upper flange 47 of the unit fixing member 37 installed at a location excluding the eaves side, there is an attachment screw 40 as an example of an attachment member formed on the lower surface portion of the outer frame 39 of the solar cell module 12. Screw insertion holes 42 are formed at substantially the same pitch intervals as the through holes 41 to be inserted (in this embodiment, two solar cell modules 12 are arranged side by side with a gap T on the unit fixing member 37. 4 formed to install !, Ru).

As shown in FIGS. 2B and 3, the coupling mechanism 35 is provided so as to protrude from the insertion space 48 formed at the other end of the unit fixing member 36 and to one end of the unit fixing member 37. And a protrusion 49 that fits closely into the insertion space 48. Here, the insertion space 48 is fixed as a unit. The member 36 is formed by being surrounded by a web 50, upper and lower flanges 38 and 43, and lips 51 and 52 formed at the tip portions of the upper and lower flanges 38 and 43, respectively. The protrusion 49 is made of, for example, channel steel, and the outer width (a) of the web 49a of the protrusion 49 is equal to the inner width (b) of the web 50 (53) of the unit fixing member 36 (37). The outer width (c) of each flange 49b, 49c of the protrusion 49 is substantially equal to the inner width (d) of the upper flange 38 (47) and the lower flange 43 (55) of the unit fixing member 36 (37).

In this case, the outer side surface 56b of the protruding portion 56a inserted into the insertion space 48 is in contact with the inner surface of the web 50 of the unit fixing member 36, and the upper and lower ends of the protruding portion 56a are the flanges of the unit fixing member 36. It abuts against the inner surface of The distance between the pair of unit fixing members 37 attached to both sides of the back surface of the solar cell module 12 is kept constant via the solar cell module 12, so that the protrusion 56a of each unit fixing member 37 is Each unit When the outer surface 56b of one protrusion 56a is about to be separated from the inner surface force of the web 50 when the fixing member 36 is inserted into the insertion space 48, the other protrusion 56a blocks the outer surface 56b. As a result, there is no gap between the protruding portion 56a and the inner surface side of the insertion space 48, and the unit fixing members 36 and 37 on both sides of the solar cell module 12 can be integrally joined. Monkey.

[0028] Next, the solar cell module 12 is fixed in the insertion space 48 at the other end (ridge side) of the pair of unit fixing members 37 that are fixed to the sloped roof plate portion 21 by grounding first. The projecting portion 49 projecting from one end (eave side) of the unit fixing member 37 is fitted and brought into close contact, and the unit fixing member 37 has a sloped roof 56 in the through hole 56 formed on the other side (building side) of the lower flange 55. The unit fixing member 37 is further joined to the ridge side end of the pair of unit fixing members 37 that are grounded and fixed previously by fitting the nuts (not shown) through the anchor bolts 44 provided on the upper surface of the plate portion 21. And can be fixed to the ground. Repeatedly fixing the building side to the sloped roof plate 21 while joining the eave side of the unit fixing member 37 to be fixed next to the building side of the unit fixing member 37 fixed to the building side to the building side. As a result, the solar cell modules 12 can be formed by mounting the solar cell modules 12 side by side from the eaves of the inclined roof 11 toward the ridge.

[0029] And by forming a plurality of rows of solar cell modules 13 in the horizontal direction, the solar cell modules 12 can be installed on the entire inclined roof 11, and the waterproof sheet used for waterproofing the inclined roof plate portion 21. It is possible to prevent sunlight from being applied to the painted part that protects the surface of the paint and to prevent the painted part from deteriorating. Furthermore, since the amount of sunlight directly hitting the sloped roof plate part 21 is greatly reduced by the solar panel 14 that also has the collective strength of the solar cell modules 12 arranged vertically and horizontally, the sloped roof board part 21 is heated in summer. It is possible to prevent the temperature of the space (attic space) between the inclined roof plate portion 21 and the ceiling portion 19 from rising.

Here, as shown in FIG. 1 and FIG. 5, each wiring on the + side and − side is not shown for each solar cell module 12 constituting a plurality of solar cell module rows 13 attached to the inclined roof 11. Are connected in series to form a solar cell unit 57 (that is, a predetermined number of solar cell modules are connected in series) .For example, solar cells are placed on the outer frame 39 of the last solar cell module 12 mounted on the ridge side. A box 58 is installed to store the output terminal board (not shown) of the unit 57. I will. Then, the output lead-out line 59 connected to the output terminal board passes through the inclined roof plate part 21, passes through the attic space, passes through the ceiling 60 and the residential floor 25, and passes through the duct 60 extending downward. Is connected to a power conditioner (inverter) 61 provided for each home 16 through a switch 62, and the output side of the power conditioner 61 is connected to the input side of the indoor distribution board 63 of the home 16. .

[0031] Further, the input side of the indoor distribution board 63 is connected to the output side of the low voltage distribution board 66 for the apartment house through the power selling meter 64 and the purchased power meter 65 for the home 16, and the low voltage distribution board 66 The input side is connected to the power transmission system 68 connected via the transformer 67 to the power transmission system on the power company side.

In addition, a power conditioner 61 connected to another solar cell unit 57 composed of a plurality of solar cell module rows 13 and an output lead-out line 59 is also provided at each downstairs home, and the solar cell unit 57 generates electric power. Power is supplied to the indoor distribution panel 63. Furthermore, the indoor distribution board 63 of each home is connected to the power supply system 68 of the electric power company through a power selling meter 64, a purchased power meter 65, and a low voltage switchboard 66.

[0032] With such a configuration, when power is generated by each solar cell module 12 and output is obtained from the solar cell unit 57, the electric power converted by the power conditioner 61 is converted into the indoor distribution panel 63. Can be consumed through. If there is a margin in the power supplied from the solar cell unit 57, the power can be supplied to the power supply system 68 of the power company via the power sale meter 64. Selling the displayed power to a power company is difficult. On the other hand, when the power supplied by the solar cell unit 57 is insufficient, and when there is no power supply from the solar cell unit 57 in the rainy and nighttime, the low voltage switchboard 66 and power purchase from the power supply system 68 of the power company. Electricity purchased via the electricity meter 65 is consumed via the indoor distribution board 63. These electric powers are bought and sold at each home. Therefore, people who do not use a lot of power in their homes will consume less electricity in total, and in some cases, it will be possible to sell part of the surplus power generated during the day to power companies, and the overall equipment will be Simplified and clear.

[0033] A method for installing a solar cell module according to an embodiment of the present invention will be described with reference to the system 10.

[0037] Then, an anchor attached to the upper surface of the first flange 22 in one side through hole 45 formed in the lower flange 43 of the pair of unit fixing members 36 to which the solar cell module 12 is fixed The bolts 44 are passed through the through holes 45 on the other side through the anchor bolts 44 attached to the upper surface of the sloped roof plate portion 21, and the nuts 46 are engaged and fastened. As a result, the two unit fixing members 36 attached to both sides of the back surface of the solar cell module 12 are placed on the eaves side of the inclined roof 11 (one side of the unit fixing member 36 is disposed in the drain groove 34 and the other end is inclined on the roof plate. Fixed to part 21).

[0038] Subsequently, the solar cell is formed by providing a gap T of 3 mm or more and 50 mm or less, for example, 5 mm, between the solar cell modules 12 from the same lip-shaped channel steel in which the unit fixing member 36 is formed. The unit fixing member 37 is formed so as to have substantially the same length as the total length when two modules 12 are arranged. The pitch of the through holes 41 formed in the outer frame 39 of the solar cell module 12 when the two solar cell modules 12 are arranged with a gap T in the longitudinal direction of the upper flange 47 of the unit fixing member 37. Screw threading holes 42 are formed at intervals. Further, the projecting portion 49 is fixed to one end portion of the inner surface of the web 53 of the unit fixing member 37 by using a rivet 54 so that the tip side protrudes, and the anchor flange is fixed to the other end portion in the longitudinal direction of the lower flange 55. A through hole 56 for the bolt 44 is formed.

[0039] Next, the opening 72 sandwiched between the lips 70 and 71 of the unit fixing member 37 is directed outward, and the upper flange 47 is directed upward in parallel, so that the outer frame 39 of each solar cell module 12 is disposed. The position of the solar cell module 12 is adjusted so that the through hole 41 formed in the upper surface overlaps the screw insertion hole 42 formed in the upper flange 47, and the mounting screw 40 is inserted into the through hole 41 and the screw through hole 42. And tighten nut 46 together. Thus, both sides of the back surface of the solar cell module 12 are attached on the upper flange 47 of the two unit fixing members 37. Since the cross-sectional shapes of the unit fixing members 36 and 37 are substantially the same, when the unit fixing member 37 is fixed to the inclined roof plate portion 21, the upper surface of the protruding wall 24 and the surface of the solar cell module 12 are not affected. There is a height difference of 5mm between them.

[0040] Then, the other end of the unit fixing member 36 as a pair attached to the eaves side of the inclined roof 11 with the protrusion 49 provided at one end of the unit fixing member 37 as a pair to which the solar cell module 12 is fixed. Each of the unit fixing members 36 After adjusting the position so that a gap S of 3 mm or more and 50 mm or less, for example, 5 mm, is formed between the end and the unit fixing member 37-end, the other end of the lower flange 55 in the longitudinal direction is adjusted. Anchor bolts 44 are fixed to the inclined roof plate portion 21 so as to penetrate the formed through holes 56, and nuts are engaged with the fixed anchor bolts 44 and fastened. As a result, the eaves side of the pair of unit fixing members 37 to which the solar cell module 12 is fixed are connected to the unit fixing members 36 installed on the eaves side by the connecting mechanism 35, and the ridge side is fixed to the inclined roof 11 to the ground. The

[0041] Further, a protruding portion provided to protrude into one end portion of the unit fixing member 37 to be fixed next in the insertion space 48 of the other end portion of the pair of unit fixing member 37 previously fixed to the ground. 49 is inserted and adhered so that a gap S of 3 mm or more and 5 mm or less is formed between the end portions, and penetrates the through hole 56 formed at the other end portion in the longitudinal direction of the lower flange 55. The anchor bolt 44 is fixed to the inclined roof plate portion 21 as shown in the figure, and the nut is engaged with the fixed anchor bolt 44 and fastened. As a result, the eave side of the unit fixing member 37 to which the solar cell module 12 is fixed is fixed to the unit fixing member 37 grounded to one eave side by the connecting mechanism 35, and the ridge side is inclined roof 11 Fixed to the ground. Then, by repeatedly grounding and fixing the unit fixing members 37 to the inclined roof 11, the solar cell modules 12 can be attached from the eaves of the inclined roof 11 toward the ridge, and the solar cell module row 13 is formed. . Furthermore, by forming the solar cell module rows 13 in the horizontal direction of the inclined roof 11 by the number of rows corresponding to the width, the solar cell panel 14 can be grounded inside the protruding wall 24 of the inclined roof 11.

[0042] The power described in the embodiments of the present invention has been described above. The present invention is not limited to the embodiments, and modifications can be made without changing the gist of the invention. The case where the solar cell panel installation method of the present invention is configured by combining a part or all of the modified examples is also included in the scope of the right of the present invention.

For example, the unit fixing member opening is arranged parallel to the outside and fixed on both sides of the solar cell module. However, the unit fixing member opening is arranged parallel to the inside and the solar cell module is installed. Both sides may be fixed. In this case, if the unit fixing member is made of channel steel without a lip, the fixing work to the inclined roof by the anchor bolt becomes easy. Moreover, you may make it provide the stopper which regulates insertion length in a protrusion part. As a result, the gap width formed between the unit fixing members can be easily adjusted, and the unit fixing member can be fixed to the ground easily.

Furthermore, although the unit fixing member is formed using a channel-shaped member, a square pipe can also be used. In addition, when using a square noise, it is necessary to form a notch in the side of the square pipe in order to engage the nut with the anchor bolt.
