Further, FIG. 3 is a partially exploded perspective side view of the solar cell array A, and FIG. 4 is a perspective side view of the solar cell array A.

As shown mainly in FIG. 1, the solar cell module M has a case (frame body) 2 formed in a frame shape in three directions and one end of which is attached to a roof. Is detachably accommodated. The overall shape and size of the solar cell module is matched to the outer shape and size of general roof tiles.

The case 2 is made of a metal material such as aluminum which is lightweight and excellent in strength. Further, the solar cell main body 1 is provided with a light-transmitting substrate such as glass or resin on the light-receiving surface, and a sealing material made of resin or the like accommodating many solar cell elements is attached to the light-transmitting substrate. There is. As the solar cell element, a single crystal or non-single crystal material such as a silicon-based semiconductor or a compound semiconductor made of gallium arsenide is used, and is electrically connected in series and / or in parallel.

On the light-receiving surface side of the solar cell main body 1, a front surface side locking member 6 that can be engaged with an adjacent solar cell module when the solar cell array A is constructed is made of aluminum or the like and is lightweight and strong. Section L made of a metallic material that has excellent
It is formed into a letter. Further, at the tip of the solar cell main body 1, there is provided a back side locking member 7 having an L-shaped cross section that can be engaged with another adjacent solar cell module or the locking member 11 arranged on the roof Y. Made of the same material as the locking member 6,
It is detachably attached to the solar cell body 1.

Reference numeral 3 in FIG. 1 denotes a support rotating portion formed in a semi-cylindrical shape, which is a support member 13 mounted on the roof.
It is rotatably supported at an angle of more than 90 ° with respect to the ground. The support 13 is made of a metal material such as aluminum that is lightweight and has excellent strength, has a convex portion that firmly holds the support rotating portion 3, and is fixed to the roof material 15.

As described above, the solar cell module is rotatable with respect to the ground at an angle of more than 90 °, and the solar cell main body 1 is attachable to and detachable from the case 2, so that the wiring work is easy. Moreover, maintenance and inspection work can be performed very easily. Further, reference numeral 9 in the drawing denotes a cable housed in the back side locking member 7, which is electrically connected to the terminal box 8 and can take out the output of the solar cell module M.

As shown in FIG. 2, the solar cell array A of the present invention is formed by stacking a plurality of solar cell modules M each having a solar cell for converting sunlight into electric energy on a roof Y of a building.

As described above, when the solar cell modules are tiled on the front surface side and the back surface side of the solar cell module, the front surface side of one solar cell module and the back surface side of the other solar cell module are stacked. Due to the locking members 6 and 7 that engage with each other, the solar cell module does not float up due to wind pressure or the like.

Further, as shown in FIG. 4, in the solar cell module M1 arranged at the lower end of the solar cell array A, the lower end 7a of the locking member 7 and an L-shaped cross section provided on the roof Y are provided. By engaging with the lower end portion 11a of the locking member 11 having a rectangular shape, the floating of the solar cell module M1 is prevented as much as possible. The locking member 11 is also made of a metal material such as aluminum that is lightweight and has excellent strength.
