Description

[0002] Photovoltaic roof is to install photovoltaic power generation device on the top of the house, and use photovoltaic technology to generate electricity in urban and rural construction fields to achieve the goal of energy conservation and emission reduction. The existing technology integrates multiple monocrystalline silicon or polycrystalline silicon power generation modules into a panel frame, and the whole is supported on the tile surface by a bracket. Since there is no integrated photovoltaic design of the building, adding photovoltaic power generation devices will also increase the roof load, which will affect the normal service life of the roof and even increase the replacement or maintenance frequency of the roof. Since the installation process of photovoltaic modules is mostly penetrating, it will cause roof leakage. Once the photovoltaic roof leaks, the operation of the photovoltaic module will be greatly affected, and waterproof renovation will be required. The photovoltaic modules of the photovoltaic roof need to be disassembled and reassembled before the roof waterproof renovation can be carried out. The workload is large, time-consuming and labor-intensive, which will cause the photovoltaic modules to be disassembled and reassembled many times during operation, affecting the long-term production capacity of the photovoltaic modules and low photovoltaic utilization efficiency.
