Photovoltaic module frame, photovoltaic module and pressing block

Abstract

The utility model discloses a photovoltaic module frame, a photovoltaic module and a pressing block, the photovoltaic module frame is used for bearing a photovoltaic laminated piece, the photovoltaic module frame comprises a main body part, the top of the main body part is provided with a bearing part and an accommodating groove located at the inner side of the bearing part, the cross section of the accommodating groove is L-shaped, and the accommodating groove is suitable for bearing the outer side edge of the photovoltaic laminated piece; the top surface of the bearing part is not higher than the top surface of the photovoltaic laminated piece, the top surface of the bearing part is an inclined surface or a step surface, and the inclined surface or the step surface is arranged in a manner of integrally extending downwards and outwards relative to the side wall of the accommodating groove. Compared with the mode that the pressing block is directly pressed on the side wall of the containing groove with the small top area, the pressure which is from the pressing block and is shared by the photovoltaic module frame can be increased, and the pressure of the pressing block on the photovoltaic laminated piece is reduced. As the top surface of the bearing part does not exceed the top surface of the photovoltaic laminated piece, accumulated water or dust is not influenced to leave the photovoltaic laminated piece and the photovoltaic module frame from the photovoltaic laminated piece, the side wall of the accommodating groove and the bearing part, and the power generation efficiency of the photovoltaic laminated piece and the uniformity of the output power are ensured.
