PURPOSE:To check entering of rainwater between a ridge side lower frame and an eaves side upper frame by covering a part of the eaves side upper frame with an extension piece of the ridge side lower frame of a solar battery panel to be arranged along the inclination of a roof. CONSTITUTION:Plural solar battery panels 30 are arranged side by side and installed on the upper surface of a base panel 20 laid extending from the ridge side to the eaves side along the inclination of a roof. In the solar battery panel 30, a frame is installed along the periphery of a solar battery 31, and an extension piece 39 formed on the ridge side lower frame 34 is arranged to cover a part of the eaves side upper frame 33. Further, a seal material 50 is interposed between the solar battery panels 30 adjacent to each other vertically and horizontally, and an air vent layer 60 is formed between the base panel 20 and the solar battery panel 30. Accordingly, rainwater is hard to enter between panels so as to improve the water cut-off performance. |
