The invention discloses a solar thin-film power generation aluminum-alloy tile. A left side edge, a right side edge, an upper side edge and a lower side edge of a solar thin-film power generation panel are respectively and fixedly connected with an aluminum-alloy left vice-frame, an aluminum-alloy right vice-frame, an aluminum-alloy upper vice-frame and an aluminum-alloy lower vice-frame; the front side edge of the outer side surface of the aluminum-alloy left vice-frame is provided with a cover plate; the rear side edge of the outer side surface of the aluminum-alloy right vice-frame is provided with a drainage groove; one surface of an aluminum-alloy corner is fixed at the upper end surface of the aluminum-alloy upper vice-frame, and the other surface and the rear side surface of the aluminum-alloy upper vice-frame are on the same plane; adhesive tape installation grooves for installing adhesive tapes are arranged on the inner side surfaces and the inner bottom surfaces of the aluminum-alloy left vice-frame, the aluminum-alloy right vice-frame and the aluminum-alloy upper vice-frame; and drainage channels are arranged between the adhesive tape installation grooves and the inner side surfaces. By the solar thin-film power generation aluminum-alloy tile, the problems of drainage of the solar thin-film power generation aluminum-alloy tile and heat dissipation of a solar thin-film power generation module are simultaneously solved, and water resistance and energy saving of a building roof can be guaranteed.
