Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting method and a mounting structure for a solar cell module, and more particularly to a mounting method and a mounting structure for easily mounting a solar cell module.

[0002]

2. Description of the Related Art In recent years, various types of buildings called solar houses have been put into practical use, in which a solar cell module having a large number of power generating elements assembled therein is provided on a roof or an outer wall, and the solar cell module is used for self-power generation. In this type of building, a supporting member is generally provided between roofing members such as a color vest at the time of roofing construction, and a plurality of battery modules are arranged on the roof while being fixed to the supporting member.

Conventionally, as a mounting structure of the above-mentioned solar cell module, one shown in FIG. 7 is known. In the figure, 10 is a solar cell module, R is a roof, and the solar cell module 10 is provided with reinforcing members 12 such as angles along a pair of sides facing the lower surface of a rectangular flat plate-shaped battery panel 11. A plurality of mounting members 20 are fixed to the roof R at predetermined positions and at fixed intervals by anchor bolts or the like. Then, when mounting the solar cell module 10, by fixing each reinforcing member 12 of the solar cell module 10 to the mounting member 20 with bolts B or the like, the plurality of solar cell modules 10 are directed from the bottom to the top on the roof. I am trying to attach them one by one.

[0004]

However, in the above-mentioned conventional mounting structure, the solar cell module 1 in which a plurality of solar cell modules 10 are mounted side by side is mounted.
Since the arrangement interval of 0 is narrow, when mounting the next solar cell module 10 next to the already mounted solar cell module 10, insert a tool near the reinforcing member 12 on the side of the already mounted solar cell module 10. However, there is a problem in that the bolt B is difficult to fasten. That is, as shown in the figure, when the solar cell modules 10 are sequentially mounted from the lower side in the figure, the battery panel 1
Although an operator's hand or a tool can be inserted between the upper edge portion of 1 and the roof R, it is difficult to insert a tool or the like between the lower edge portion of the battery panel 11 and the roof R. The mounting work was difficult. The present invention has been made in view of the above problems, and an object of the present invention is to provide a mounting structure that facilitates mounting work when mounting a plurality of solar cell modules side by side.

[0005]

In order to achieve the above-mentioned object, an aspect of the invention according to claim 1 is a method of mounting a module and a module, which is a mounting fitting provided on one side of a lower surface of a solar cell module. The fitting receiving fittings of the metal fittings are arranged side by side on the mounting surface at intervals in the mounting direction, the fitting fitting fittings are fitted and locked to the fitting fittings, and the mounting fittings on the other side of the lower surface of the solar cell module Was fastened to a mounting member fixed to the mounting surface, and this operation was sequentially repeated in the mounting direction to arrange the solar cell module on the mounting surface.

According to a second aspect of the present invention, there is provided a solar cell module mounting structure in which a plurality of substantially rectangular flat plate-shaped solar cell modules are mounted side by side on a mounting surface of a building. While fixing the attachment fitting pieces to the fastening members at the opposite side positions,
A fitting receiving member having an insertion groove into which the mounting fitting piece can be inserted at a position corresponding to the mounting fitting piece on the mounting surface, and a mounting member which can be fixed to the fastening member by a connecting member are alternated. It was installed in.

In the solar cell module mounting structure according to the present invention, the fitting receiving member defines the insertion grooves with spring pieces at regular intervals on the base piece fixed to the mounting surface of the building. It can be configured in such a manner that the spring piece is elastically attached to the attachment fitting piece inserted in the insertion groove (claim 3). Further, the mounting structure of the solar cell module of the present invention can be configured in such a manner that elastic members are fixed to both side surfaces of the insertion groove of the fitting receiving member and the mounting fitting piece can be pinched. (Claim 4).

[0008]

According to the solar cell module mounting method and mounting structure according to the first and second aspects of the present invention, the fitting bracket (member) and the mounting member are mounted on the building mounting surface of the solar cell module. Tool (piece) and fastening member (mounting bracket)
Since the solar cell module is installed alternately at an interval equal to the interval between and, the solar cell module fixes the fastening member and the attachment member with the connecting member after inserting the attachment fitting piece into the insertion groove of the fitting receiving member. Therefore, the next solar cell module can be easily attached next to the already installed solar cell module. That is, when installing the next solar cell module next to the already installed solar cell module, on the already installed solar cell module side, it suffices to insert the mounting mating piece into the groove of the mating receiving member, and tighten the bolts. Since it is not necessary, the installation can be done easily and quickly.

Further, the mounting structure according to claim 3 can press the mounting fitting piece inserted into the groove by its elasticity with the spring piece, and similarly, the mounting structure according to claim 4 is the elasticity of the elastic member. The solar cell module can be supported more firmly and high reliability can be achieved because the solar cell module can be pressed down with.

The fitting receiving member 30 is formed of a metal material having excellent corrosion resistance such as stainless steel or aluminum alloy or a resin into a block shape having a length shorter than half the length of the fitting fitting piece 13. Like the mounting member 20, it is fixed to the roof R by anchor bolts. The fitting receiving member 30 has an insertion groove 30 that is opened in parallel upward in the inclination direction of the roof R.
a is formed so that one piece portion 13a of the mounting fitting piece 13 can be inserted. The fitting receiving member 30 holds one side of the solar cell module 10 by inserting one side of the mounting fitting piece 13 of the solar cell module 10 into the insertion groove 30a.

When the roof R is a concrete roof or a roof tile roof, the mounting member 20 and the fitting receiving member 30 are used.
Is fixed with anchor bolts or screws, but in a slate-roofed or tile-roofed roof, a support member extending between the overlapping portions of the slate or roof tile is provided, and this support member is provided in advance in the mounting member 20 and the fitting receiving member 30. When carrying out roofing work, the support member is fixed to the base plate (Fig. 4 described later).
Further, the mounting member 20 and the fitting receiving member 30 described above are configured to have short lengths corresponding to the battery panel 11, but the reinforcing member 1
It is also possible to make the length substantially equal to 2U or the mounting fitting piece 13, or the length over the entire installation area of the roof R.
