(JP10121668-A)      The roof includes a fixing member (105) on which several solar battery roof sheathings (103) are are arranged adjacent to each other by a fixing tool. The sheathings are separated by a predetermined gap and are fixed detachedly. A cap (107) is arranged on the upper part of the gap between the sheathings.    ADVANTAGE -   Reduces construction cost. Prevents mistake in construction resulting from complicated wiring work. Corresponds to maintenance management peculiar to solar battery.    (US6182403-B1)      The roof unit includes a number of combinations of solar battery and roof panels (103), each having flanges at two opposite sides, placed adjacent to each other with clearance on a joining or fixing member (105). The adjacent combination solar battery and roof panels are fixed to the joining or fixing member in the clearance by a removable fixture (104), and a removable cap (107) is placed in the upper part of the clearance. A junction box for drawing an output of the solar battery to the outside is provided in the flange and wiring members connected to the junction boxes of the combination solar battery and roof panels adjacent to each other are connected in the clearance.    The joining or fixing member is rod-shape along the clearance, or a sheathing roof board of flat plate shape. The combination solar battery and roof panel is constructed in such an    arrangement that a solar battery element is sealed on a backing with a filling material and that a protecting film is provided on a surface. A removable deformation preventing member is    fixed in a direction perpendicular to the flanges. In the combination solar battery and roof panel a rib is formed in a direction perpendicular to the flanges.    ADVANTAGE -   Arrangement simplifies work at working site, decreases construction cost, and decreases work errors. Measurement or replacement of each module can be made even after    mounted, thus providing a practical vertical-roofing roof excellent in maintainability and also in wind endurance.
