Abstract: Between a light receiving glass and a backside glass a plurality of solar battery cells form a matrix of solar battery cells and a translucent, intermediate layer of film is also interposed to configure a photovoltaic module having a light receptive, glass laminate structure, wherein at least one of a back surface of the solar battery cell and a front surface of the backside glass observed indoors has a film stuck thereon. For a photovoltaic module having a light receptive, multi-layer structure, a glass observed indoors also has a film stuck thereon. The solar battery cell can thus have a back surface with a lead frame, a mark of paste applied for collection of electricity covered with the film to provide an improved, externally observed design and an increased product value.

Abstract: A solar battery module in use has a solar battery panel and a frame body. The solar battery panel is constituted by laminating a front cover, a filler, a crystal solar battery cell, another filler, and a back cover on one another in this order. The frame body surrounds the outer periphery of the solar battery. At each corner of one side of the frame body is formed a notch with its open end facing toward the light-receiving surface. Under rainfall, rainwater which fell down onto the light-receiving surface flows toward below the solar battery module, and is then held back by the frame member provided on the frame body. The rainwater remaining flows into the notch. In the notch, the rainwater is guided toward above the frame member on the principles of siphon action so as to be discharged out of the solar battery module.
