The tile-integrated solar cell module is a solar cell panel to which a frame that protects the end face of the solar cell panel is attached, and the frame is directly fixed to the roof base without using mounting brackets to be one of the roofs. It constitutes a part.

By the way, in this tile-integrated solar cell module, as the solar cell panel generates electricity, the frame holding the solar cell panel may also be charged. Therefore, in order to prevent electric shock and malfunction, a grounding structure is required to release the electric charge charged in the frame.
In a general solar cell module with an integrated roof tile, the ground wiring is screwed to the frame of the solar cell module, laid on the roof base, and then connected to the frame of the adjacent solar cell module by the ground wiring. Then, by connecting the frame of a specific solar cell module from the laid solar cell modules to the ground, the charge charged in the frame of each solar cell module is collectively released to the ground.

The holding member 6 is in contact with the folded-back portion 172 of the insertion fitting 21 to be held, and the holding member 6 is electrically connected to the holding member 6 of the solar cell module 2C on the building side. That is, since the electric charge charged by the solar cell module 2A can be released to the solar cell module 2C without using a separate wiring member, the workability is better than before and the installation work can be simplified. Furthermore, it is possible to reduce the number of parts such as wiring members.

It is blocked by 69, and it is difficult to enter the gap between the eaves side end surface of the solar cell panel 5 and the end surface side buffer portion 103 of the first gasket portion 100. Therefore, it is possible to prevent the solar cell panel 5 from being damaged due to the intrusion of rainwater from the eaves side end surface of the solar cell panel 5.

According to the roof structure 1 of the first embodiment, since the eaves side frame portion 16 of the solar cell module 2a is provided with the snow stopper 66, as shown in FIG. 36, the snow stopper 66 roofs the snow even in a cold region. The inclination of the roof can prevent it from falling to the ground.
Further, since the snow stopper 66 constitutes a part of the divided piece 22, the snow stopper 66 can be installed at the same time as the eaves side frame portion 16 is assembled, and the work of installing the snow stopper on site is unnecessary. Will be. Therefore, the workability is better than the conventional one, and the workability can be simplified.

Therefore, even if the snow melts and becomes water during the daytime or the like, water can flow along the slope from the notches 58, 59, 64 which are the water passages.

According to the solar cell module 2 of the first embodiment, the insertion fittings 20 and 21 and the eaves side frame portion 16 are connected by the reinforcing bars 162 and 163, and the insertion fitting 20 and the left side frame portion 17 are connected and inserted. Since the metal fitting 21 and the right frame portion 18 are connected, the holding member 6 is unlikely to be deformed in the vertical and horizontal directions. Therefore, it is possible to prevent the holding member 6 from being deformed when a load is applied to the snow stopper 66 due to snow accumulation.

According to the solar cell module 2 of the first embodiment, in the eaves side frame portion 16, the lengths of the first ridge portion 107 and the first concave groove 69 that are fitted to each other are the lengths of the eaves side sides of the solar cell panel 5. It is more than 1/3 of the 11th.
