Is taken out from the lead terminal.

[0003]

The maintenance and management of the lead terminals for extracting electric power from the solar cell are very troublesome because they protrude in a state of being exposed on the surface of the tile. Moreover, in order to prevent accidents such as electric shock and short circuit during construction, it is not desirable in terms of workability, such as using nerves for work.

Accordingly, an object of the present invention is to provide a power generation apparatus using a roof building material with a solar cell mounted thereon, which is easy to maintain and manage and is excellent in safety and reliability.

[0005]

In order to achieve the above-mentioned object, according to the present invention, at least two of the current collecting bars are arranged on a plurality of current collecting bars arranged on a roof base. Place the roof building material in the roof building material,
While a converter for converting DC from the solar cell to AC and a primary coil through which current from the converter flows are arranged, inside the current collecting bar, a primary coil facing the primary coil in the roof building material is disposed. A current collecting coil serving as a secondary coil and a fixed magnetic body having a fixing hole are arranged, and a coupling magnetic body is pierced from above the roof building material in the order of the primary coil, the current collecting coil, and the fixing hole to collect the current. A magnetic circuit for extracting electric power is formed on the coil side, and the roof building material and the current collecting bar are connected.

Accordingly, the solar cell, the converter, and the primary coil are disposed inside and are not exposed, so that they do not come into direct contact with the roof building material, and no accident such as electric shock or short circuit occurs. In addition, maintenance and management become easier, and the operation does not need to be nervous.

Further, according to the present invention, a region of a primary coil provided in a roof building material through which a coupling magnetic material penetrates;
A fixing magnetic body region having a current collecting coil and a fixing hole provided in the current collecting bar is made of an elastic member, and can be moved back and forth and right and left.

Accordingly, when the coupling magnetic body is inserted from above the roof building material set on the current collecting bar, even if each of the coil holes and the fixing holes of each coil is slightly misaligned, the insertion of the coupling magnetic body is prevented. By moving back and forth and left and right with this, the insertion work can be performed easily and the roof building material and the current collecting bar can be securely connected and fixed.

According to the present invention, the tip of the coupling magnetic body is tapered.

Thus, when the coupling magnetic body is inserted, it can be easily inserted into each coil and the fixing hole.

Further, in the present invention, the primary coil and the current collecting coil have a configuration in which a single-phase alternating current or a multi-phase alternating current flows.

This makes it possible to use a single-phase alternating current to a multi-phase alternating current.
