c) is formed, and a plate pressing portion (16d) for pressing the metal roof plate (18) is formed on the upper portion of the leg portion (16a).

The plate connector (16) is made of a long metal member such as stainless steel. The outer peripheral plate (18) is formed by cutting a long strip-shaped steel plate or a copper plate or the like wound into a roll into a desired length. (22) is a sheet-like solar cell panel, and the panel (22) and the roof panel (18) are set to have substantially the same width. The solar cell panel (22) is overlaid on a shingle (18). A pair of roof panels (18) and (18) on which the solar cell panels (22) are stacked are arranged on the upper surface of the base material (2) at a predetermined interval with the groove (4) as a boundary. And
The side part of each roof plate (18) (18) is mounted together with the solar cell panel (22) on the plate end receiving portions (14i) (14j) of the corresponding plate receiving member (14). A plurality of washers (not shown) are fixed to the upper surface of the base material (2) from above the waterproof sheet (10), and the lower surfaces of the roof plates (18) and (18) are bonded to the upper surfaces of the washers by an adhesive. Is done. The roof panel (18) and the solar panel (22) may be bonded by an adhesive.

A leg (16a) of a plate connector (16) is inserted into a facing portion of a pair of roof panels (18) and (18) on which solar cell panels (22) are stacked. 16
a) is pressed into the hook (14f) of the plate receiving member (14). In this state, the opening (1) of the plate connector (16) is
6c) is engaged with the lower surface of the hook claw (14f), and the plate pressing surface (16d) of the plate connector (16) is connected to the plate end receiving portion (14i).
(14j) The upper roof plate (18) is pressure-bonded to the upper surface of the side part of (18).

As a result, the opposing sides of the roof panels (18) and (18) and the solar cell panels (22) and (22) on the roof panels (18) and (18) are connected to the plate pressing portion (16d) of the plate connector (16).
And the plate end receiving portions (14i) (14j). A pair of shingles (18) (18) and a solar panel (22) thereon located in another groove of the base material (2)
The opposing side portions of (22) are also connected to the plate receiving member in the groove by the configuration shown in FIG. 1 to constitute a roof on which the solar cell panel (22) is unfolded as a whole. In the above configuration, the inner wall surface of the garter (6) and the plate receiving member (14)
The space (2) is formed between the outer wall of
0) is formed, and rainwater flows through this space (20).

Therefore, the garter (6) and the plate receiving member (1)
4) Rainwater is guided to the upper part by capillary action,
It does not reach under the outer plate (18), thereby preventing rain from leaking. Further, the roof panels (18) and (18) and the solar cell panels (22) and (22) expand and contract due to heat change. With the expansion and contraction phenomenon, the roof panels (18) and (18) and the solar panel Battery panel (22) (22)
The plate receiving member (14) connected to the roof plate (18) (1) is guided by the guide portions (6d) (6e) of the garter (6).
8) slide in the direction to escape from the pressure from

By the sliding operation of the plate receiving member (14), the roof plate (18) and the solar cell panel (22) are
There is no pressure that causes distortion such as wrinkles. In the present embodiment, the garter (6) and the plate receiving member (14) are formed separately, but the garter (6) and the plate receiving member (14) may be integrally formed. The solar cell panel (22) is connected to the inverter (2) as shown in FIG. 5A.
4) to the load (26) and the power company (28). If the amount of power generation is insufficient, a system that buys electricity from the power company (28) and sells it to the power company when the amount of power generation is insufficient can be adopted. Also, as shown in FIG. 5B, a system independent of the power company can be adopted,
The solar cell panel (22) is connected to the storage battery (30) and the inverter (24), and the load (26) is driven by the output of the inverter (24).

[0014]

Since the present invention is constructed as described above, there is an effect that the solar cell panel can be easily installed on the roof without processing the roof panel.
