PROBLEM TO BE SOLVED: To make connection definitely by providing a projection of acute angle in the lower end portion of an almost channel-shaped connecting fittings, linking the connecting fittings astride an adjacent end frame of a solar cell module, and peeling off a coating by the projection and making electrical connections. SOLUTION: Connecting fittings 44 are formed from a rectangular horizontal piece 45 and a pair of vertical piece 46 extended downward vertically, and a bolt inserting hole 47 is made in a horizontal piece 45 and a projection of a sawtooth acute angle is formed at a lower end of a vertical piece 46. Next, stop fittings 54 are inserted to the frame, and vertical pieces 46, 51 of coupling fittings 50 and connecting fittings 44 are inserted to a linking groove 43 of both adjacent module frames 34 from the above, and the coupling bolt 57 is tightened. Then, a projection of connecting fittings 44 peels off the coating of a linking piece 41 of the module frame 34 and cuts into the fittings 44, and both the module frames 34 are electrically connected through the connecting fittings 44. Thus, the solar cell module can be grounded efficiently. |
