Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for mounting a solar cell on a roof of a building such as a house.

[0002]

2. Description of the Related Art When solar cells are installed on the roof of a house,
Conventionally, a gantry is mounted on a roofing material such as a tile and a solar cell is fixed to the gantry.

[0003] However, in such a structure, the solar cells protrude above the roof, making the appearance unsightly. In addition, when the solar cell is installed from the beginning of the construction of the house, the solar cell mounting portion is similar to other roofs. Since the installation work of the solar cell must be newly performed after the roofing work, there is a drawback that the construction period is long, and the number of members is large and the cost is high.

Therefore, in order to solve such a problem,
Conventionally, on a general roof part, a piece of wood is fixed on a field board and a general tile material is installed to raise the general roof part, and the solar cell installation part is a metal sheet roofing steel sheet laid on the field board. It is considered that a roof is provided with a solar cell thereon so as to prevent a step from being formed between the general roof section and the solar cell installation roof section (see Utility Model Registration No. 3026979).

[0005]

As described above, in the conventional solar cell installation structure, the mounting frame of the solar cell is fixed on the roof surface in advance with screws or bolts and covers the fixed portion. Is fixed to the gantry, and the solar cell modules are attached to the frame one by one. Therefore, two steps of attaching the gantry and attaching the frame are required. Since it is a structure to be attached to each sheet, there are disadvantages that the number of work steps on site is increased and the number of members is increased.

[0006] The present invention provides a solar cell mounting apparatus which solves the conventional drawbacks described above, enables the solar cell to be mounted in a short time, and requires only a small number of members. The purpose is to do so.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a solar battery unit comprising a pair of left and right frames and a solar battery module mounted between the frames in a row direction on a roof. Installed and fixed to the roof structural material with bolts, the fixing pieces protruding outside of each frame, and covering the fixing parts with cover pieces protruding from each frame above the fixing pieces and the bolts. It is characterized by.

In the above, it is conceivable to cover the space between the frames by attaching a lid plate to the end of each frame in the direction of inclination of the roof.
