<p>PROBLEM TO BE SOLVED: To prevent rainwater infiltration from a joint gap between solar battery modules, to thereby excellently implement flashing. SOLUTION: A stepped frame (6) is installed on a roof substrate (5) along a roof declining direction, and mutually facing edges of the solar battery modules (1) and (1) longitudinally adjacent to each other are mounted on a sealing material (40) attached to each step of the frame (6). Then, an upper portion of the joint gap (50) formed between the edges is covered with a joint material (51), and edges of the joint gap (50) are covered with facing materials (52).</p> |
