The efficiency of energy conversion is enhanced by taking a countermeasure against heat escape (radiation), the water sealability is enhanced between the solar battery modules, and the voltage required is obtained by one roof panel to make it possible to supply power efficiently. A roof Y installed with solar batteries is formed by supporting the solar battery modules (3) by core woods (6) and frames (11) on a base panel (2). The heat of the solar batteries is dissipated by the air flow through the ventilating layers (1A) formed between the modules (3) and the base panel (2). The modules (3) are fitted through sealing materials (12) and (14) into the C-shaped parts (13 and 15) of the frames in order to ensure the waterproofness. Also, a frame (32) is used around each module (3), and the extended piece (39) of each frame (32) on the eaves side is overlaid on each other to prevent rainwater from entering the spaces between them. In one roof panel (1), a specific number of solar cells (10) are arranged to produce a required voltage. Thus by adjusting the voltage, any excessive or short supply of power does not occur. <IMAGE> |
