Patent ID: 8330037

Claim:
A photovoltaic module comprising: a photovoltaic module body including a plurality of solar cells sealed between a surface member and a backside member with a sealing material; a plurality of frames mounted to a periphery of the photovoltaic module body; and a press-insertion member connecting each of the frames, wherein the frames including a main body having a hollow structure along a direction on which the frames extend and a fit-engagement portion fittingly receiving the periphery of the photovoltaic module body, the main body being formed in a roughly rectangular shape in section perpendicular to the direction on which the frames extend, the roughly rectangular main body including a first side and a second side, the first side facing at a side of the photovoltaic module body, the second side being opposite the first side, each of the frames being mutually connected by inserting the press-insertion member into the main body, a thickness of the region in the first side where the press-insertion member is inserted is thinner than that in the second side where the press insertion member is inserted; and the first side being deflected toward the photovoltaic module body with an insertion of the press-insertion member.
