PROBLEM TO BE SOLVED: To solve the problem that, when mounting a photovoltaic power generation panel onto a roof surface conventionally, manufacturer-dedicated brackets are fixed onto the roof surface by piercing holes using machine screws and bolts or the like after waterproof sealing but there is the risk of occurrence of any problem caused by rain leaking from mounting brackets, unavoidably in future, because of the actual construction situation that construction propriety of the waterproof sealing cannot be confirmed on the job site, or aging of the waterproof sealing per se.SOLUTION: A main rain leaking factor in photovoltaic power generation installation is a waterproof sealing defect of a mounting bracket to a roof surface or aging of the sealing per se. By adhering and mounting rain leaking prevention reinforced hardware to a water upper side of a manufacturer-dedicated mounting bracket (in a roof upper direction) through sealing or the like, rainwater is prevented from directly falling on the panel mounting bracket and most of rain leaking caused by aging can be prevented, thereby hedging risks. |
