The bending stops at a position lowered by the predetermined distance a, and the deformation of the solar cell module 14 is prevented.

For this reason, even if an operator gets on the horizontal frame 23 during, for example, construction work, the load is dispersed to the roof panel 15 or 16 and the solar cell module 14 is not likely to be damaged. .

Further, in the first embodiment, since the center support member 25 is provided substantially at the center of the horizontal frame 23, the possibility of further deformation and damage is reduced.

Although the first embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the first embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Even this is included in the present invention.

For example, in the first embodiment, the roof panel 15 on which eight or four solar cell modules 14 are arranged is provided.
Or 16 has been described, but not particularly limited to this,
2-3 or 5 or more solar cell modules 14 ...
Even if the waterproof base material is laid on the lower surface side of the solar cell module 14 disposed on the roof structure, on the upper surface of the base plate 15a. The number, shape, number of rows and columns of the solar cell module 14 and the like are not limited.

[0110]

As described above, according to the first aspect of the present invention, in the lower space of the solar cell module disposed on the roof structure, the upper surface of the roof panel member is provided. Since the waterproof base material is laid, the water flowing down the roof flows down on the waterproof base material.

For this reason, the construction workability can be improved by laying the waterproof base material in advance while having a waterproof structure in which there is no danger of flooding in the attic space or the like.

According to the second aspect of the present invention, the connecting member is engaged with and connected to opposing ends of the two solar cell modules, and the connecting member is fixed to the roof panel plate by fixing means. By fixing the solar cell module to the roof panel, the solar cell module can be maintained at a predetermined distance from the upper surface of the roof panel.

Therefore, water flowing down the roof can flow down onto the waterproof base material on the lower surface side of the solar cell module.

[0114] According to the third aspect,
The horizontal frame connects the opposite ends of the solar cell modules connected in the flow direction over substantially the entire width of the module.

In the concave groove formed in the horizontal frame,
A plurality of support members are fitted and secured to the roof panel upper surface by the support members.

The upper and lower edges of the solar cell module are reinforced by the horizontal frame to improve rigidity, and the supporting members are fitted in the concave grooves at predetermined intervals. Rainwater, etc. flows down between the clubs and drains smoothly toward the eaves.

Further, according to the fourth aspect, the locking projection formed in the engaging concave portion of the connecting member locks the end of the solar cell module in an inserted state.

Since an elastic member is attached to the end, the locking projection presses and deforms the elastic member.
Fits incapable of falling off.

[0119] According to the fifth aspect,
A connection member having substantially the same shape as a connection member used for connection between the respective solar cell modules is engaged with a lower end portion of the solar cell module disposed on the roof panel plate and located at the lowest position in the flow direction. At the same time, since the connecting member is fixed to the roof panel plate, the processing of the lower end portion can be performed with substantially the same member as the connecting member for connecting the other solar cell modules. Therefore, there is no need to separately use a member for processing the lower end portion, so that the manufacturing cost can be reduced.

[0120] According to the sixth aspect,
A connecting member having substantially the same shape as a connecting member used for connection between the respective solar cell modules is engaged with an upper end of the solar cell module disposed on the roof panel plate and located at the uppermost part in the flow direction. At the same time, the connecting member is fixed to the roof panel plate, and the lower end of the draining plate arranged between the other roof panel member is engaged with the upper end of the connecting member. The waterproof construction can be easily completed by engaging the engaging recess formed on the opposite side to the engaging recess.

As described above, the workability is improved, and
The processing of the upper end portion can be performed with substantially the same member as the connecting member for connecting the other solar cell modules, and it is not necessary to use a separate member for processing the upper end portion. Can be reduced.

According to the seventh aspect of the present invention, since the solar panel module is provided in advance on the roof panel plate, work at heights can be reduced and only the roof panel can be provided. Thus, a roof with solar cells, which has been waterproofed, can be formed.

And, according to the eighth aspect,
When the solar cell module is pressed from above and tries to deform, the horizontal frame is integrally provided with deformation preventing legs for preventing the lowering thereof in the vertical direction by bringing the lower end into contact with the roof panel plate. The deformation is prevented.

For this reason, for example, even if an operator gets on the horizontal frame during construction work, the load is dispersed to the roof panel material, and there is no possibility that the solar cell module is damaged. It has a beneficial effect.
