PURPOSE:To enlarge the effective area of the generation of electricity of a solar cell module, and to reduce manufacturing cost and fitting cost thereof by a method wherein the mudule is fixed to a roof using the back plate thereof formed with fitting parts by protruding the adjoining two sides of the square back plate from the transparent surface plate. CONSTITUTION:The adjoining two sides of the back plate 14 of a solar cell module on the opposite side from a glass plate 1 covering an a-Si layer are protruded from a glass plate 1 and a resin layer 3 to form fitting parts 15, 16. One 21 of such a solar cell module is fixed on the roofing 7 of a roof using a nail 31, the right side of another module 22 is superposed on the fitting part 16, the fitting part 16 of the module 22 is fixed by a nail, and a sealing agent 32 is filled up in a gap between the modules. Penetrating holes are formed according to notch parts 19, and four modules of the periphery are fixed to a sheathing 7 and a rafter 13 by washers 34 and screws 35. Because the module is provided with no frame body, shade is not generated, the a-Si layer can be arranged up to close by the periphery of the module, and the effective area of the generation of electricity is enlarged. |
