Each of the solar cells 7 extends along the substrate 6 and is a long and sheet-like battery substrate 8 attached to the surface (upper surface) of the substrate 6, and embedded in the battery substrate 8. A plurality of element blocks 9 provided apart from each other in the longitudinal direction, and plus and minus output wirings embedded in the battery base 8 and extending over substantially the entire length in the longitudinal direction and connected to the respective element blocks 9. 10,11
Is provided at the longitudinal end of each of the solar cells 7.
The ends 10a, 11a of the output wirings 10, 11 are located as electric terminals.

The battery substrate 8 is made of resin and is transparent. The element block 9 is configured by an element that receives sunlight and directly converts the light energy into electricity. This element is, for example, a pn junction element made of single crystal, polycrystal, or amorphous silicon. The output wirings 10 and 11 are made of copper or aluminum wire.

The electricity generated in each of the element blocks 9 is collected by the output wirings 10 and 11 and output from the ends 10a and 11a. The ends 10a, 11
“a” is connected to another device 12 such as a secondary battery by an electric wiring 13, and electric power is output to the other device 12 through the electric wiring 13.

1 and 2, in the width direction of the substrate 6 of the photovoltaic power generator 4 (indicated by an arrow B in each figure), the side edges 14 of the substrate 6 and the solar cell 7 are positioned closer to each other. Each side edge 15,
15 is deflected toward the center of the substrate 6, that is,
A part of each side end portion 16 of the base material 6 is a portion where the solar cell 7 is not attached.

Then, of the plurality of solar power generators 4 arranged in parallel on the upper surface of the roof 3 of the building 2, opposing side ends of the substrates 6, 6 of the adjacent solar power generators 4, 4 Part 1
The solar cells 6 and 16 are joined to each other by welding using high frequency or the like (reference numeral D in FIG. 2), whereby the solar power generators 4 and 4 are joined to each other.

In FIG. 3, among the plurality of photovoltaic power generators 4 arranged side by side on the upper surface of the roof 3 of the building 2, the photovoltaic power generators 4, 4 adjacent to each other at a distance in the width direction B are paired with each other.
A fixture 19 is provided to secure the facing edges to the roof 3 of the building 2. Each of the photovoltaic power generators 4 is attached to the roof 3 of the building 2 by the fixation by the attachment 19 and the mutual connection D of the photovoltaic power generators 4 and 4 described above.

The mounting fixture 19 has a gutter-shaped long mounting base 20 extending along the roof 3.
Is mounted on the roof 3 between the two photovoltaic power generators 4 and 4. The attachment 19 has a holding member 21 which is detachably engaged with the attachment base 20 from above the attachment base 20. The attachment 19 is made of metal such as aluminum or iron, but the holding member 21 may be made of gasket rubber.

When the holding member 21 is locked to the mounting base material 20 and the holding member 21 is attached to the roof 3 of the building 2, that is, the outer side of the solar power generator 4 in the width direction B. When the holding tool 21 is attached to the roof 3 of the building 2 in the vicinity, the holding tool 21 attaches the surface of the side end 17 of the solar cell 7 of the photovoltaic power generator 4 to the mounting base on the building 2 side. As a result, the side end portions 16 and 17 of the photovoltaic power generator 4 are sandwiched between the mounting base material 20 and the holding member 21, and as described above, A power generator 4 is attached to the roof 3 of the building 2.

According to the above configuration, the solar power generator 4 can be wound in a roll shape in the longitudinal direction.

For this reason, even if the photovoltaic power generator 4 has a large area when unfolded, when the photovoltaic power generator 4 is rolled, its outer shape (volume) should be made sufficiently small. Can be.

Therefore, even if the photovoltaic power generator 4 has a large area, it can be rolled into a small shape.
The transportation from the production factory to the site where the building 2 exists, and the transportation of the building 2 to a high place such as the roof 3 can be easily performed.

When the solar power generator 4 is deployed at a desired position on the roof 3 to which the solar power generator 4 is to be mounted, the solar power generator 4 having a sufficiently large area per one sheet can be obtained. Can be attached.

Therefore, even when the photovoltaic power generator 4 is mounted on a large area of the roof 3, the number of the photovoltaic power generator 4 is small, and the mounting work of the photovoltaic power generator 4 is correspondingly performed. Can be easily done.

The solar power generator 4 is provided with a solar cell 7
Can be wound in a roll shape so that the inside of the photovoltaic power generator 4 is in a roll shape.
At the time of transportation or storage, the solar cell 7 is attached to the base material 6.
Will be covered by

Therefore, it is possible to prevent the solar cell 7 from coming into contact with other objects during transportation or storage, thereby preventing the solar cell 7 from being damaged, and also prevent the solar cell 7 from receiving sunlight. Unnecessary power generation is prevented.

Therefore, since the solar cell 7 does not need to be provided with a dedicated protective cover, protection of the solar cell 7 is achieved by a simple configuration.

Further, as described above, the end 10a of the output wiring 10 is located at the end of the solar cell 7 in the longitudinal direction.

For this reason, when a plurality of photovoltaic power generators 4 are to be mounted on a large area of the building 2, if the plurality of photovoltaic power generators 4 are mounted side by side in the width direction, Each output wiring 1 of each of these solar power generators 4
The zero end portions 10a can be arranged in a row in a state of being close to each other in the width direction B, and are prevented from being dispersedly arranged as in the related art.

Therefore, even if the number of the photovoltaic power generators 4 is large, the wiring work of the electric wiring 13 for connecting each end 10a of each output wiring 10 to another device 12 such as a secondary battery can be performed. It can be done easily.

As described above, the solar cell 7
Is a long sheet-like battery base 8 extending along the base 6 and attached to the surface of the base 6, and a plurality of the battery bases 8 embedded in the battery base 8 and separated from each other in the longitudinal direction. And the output wirings 10 embedded in the battery base 8 and extending over substantially the entire length in the longitudinal direction and connected to the respective element blocks 9.

For this reason, when the photovoltaic power generator 4 formed into a sufficient length in advance is made to have a length suitable for the part of the building 2 to be mounted, the space between the adjacent element blocks 9 and 9 is required. The solar power generator 4 may be cut off. An example of the cut portion is indicated by reference numeral C in FIG.

Therefore, the solar power generator 4 having a desired length can be obtained by a simple operation.

At the end in the longitudinal direction A of the photovoltaic power generator 4 having a desired length obtained by the cutting, the cut end of the output wiring 10 by the cutting is set as the end 10 a of the output wiring 10. .

In the width direction B of the substrate 6 of the photovoltaic power generator 4, the solar cell 7
Is deflected toward the center of the base material 6.

For this reason, when a plurality of photovoltaic power generators 4 are arranged side by side in the width direction B and attached to the building 2, the opposing side end portions 16 of the base material 6 of the adjacent photovoltaic power generators 4
The members 16 are joined to each other by welding, sewing, or the like without being disturbed by the side edge 15 of the solar cell 7.

Therefore, the adjacent solar power generators 4 and 4 can be easily coupled to each other without damaging the solar cell 7.

As described above, when the photovoltaic power generator 4 is mounted on the building 2, the holding member 21 is mounted on the building 2 in the vicinity of the outer side of the photovoltaic power generator 4 in the width direction B. The surface of the side end portion 17 of the solar cell 7 is pressed toward the building 2 by the presser 21.

For this reason, the side ends 16 and 17 of the base member 6 and the solar cell 7 are pressed against each other by the presser 21, so that rainwater may enter between the side ends 16 and 17. The solar cell 7 from the substrate 6
Is prevented from peeling off, and the solar power generator 4
The service life is improved.

Then, as described above, the solar power generator 4
When the presser 21 is used to attach the photovoltaic power generator 4, as described above, the side edges 14, 15 of the base material 6 and the solar cell 7 are positioned close to each other in the width direction of the solar power generator 4. B allows the presser 21 to be smaller.

Therefore, the solar power generator 4 can be mounted with a simple structure so as to improve the life of the solar power generator 4 described above.

In FIG. 3, the mounting fixture 19 has a closed space 22 surrounded by a mounting base material 20 and a holding fixture 21.
The side edge 14 of the base material 6 and the side edge 15 of the solar cell 7 are located in the closed space 22.

Further, since the battery substrate 8 of the solar cell 7 has a certain degree of elasticity, when the photovoltaic power generator 4 is attached as described above, the side end 17 of the solar cell 7 is Is pressed, the elasticity of the battery substrate 8 seals the pressed portion.

Therefore, it is possible to prevent rainwater from entering the closed space 22 with a simple configuration, that is, to prevent rainwater from entering between the base material 6 and the solar cell 7 with a simple configuration. Is prevented.

In the above case, if a sealing material is interposed between the surface of the side end portion 17 of the solar cell 7 and the pressing surfaces of the pressing members 21, the above-mentioned sealing property is further improved. Also, if rainwater enters the enclosed space 22 through the space between the pressing surfaces, the rainwater flows through the mounting base 20 and is drained out of the building 2.

Although the above description is based on the illustrated example, a plurality of rows of the illustrated solar cells 7 may be attached to the base material 6 of one solar power generator 4 .

The following figures show the second to fourth embodiments. Each of these embodiments has many points in common with the first embodiment in configuration and operation.
