A solar panel roofing board and a general roofing board are electrically connected directly or indirectly via a clip, spring, vis, and so on. Further, a conductive member is provided between the roofing boards and a roof installation surface, and the roofing boards are connected to the conductive member. Accordingly, potentials of the roof configuring parts of a photovoltaic power generation roof using a solar panel roofing board become the same, thereby it becomes easy to ground them as well as a connection point to the ground is arbitrarily selected. Further, a metal sheet roof provided for securing fire resistance is used to achieve the above object. <IMAGE> |
