The waterproof tiles used in photovoltaic roofs need to have the following important properties to ensure that they can effectively protect the roof in a complex environment and extend their service life:
1. High weather resistance: photovoltaic roofs are exposed to sunlight, rain, snow and other environments for a long time. Waterproof tiles must have excellent UV resistance, high temperature resistance and low temperature resistance, and be able to maintain stable performance under extreme climatic conditions.
2. Excellent waterproof performance: The core function of waterproof tiles is to prevent water from penetrating into the roof, so they need to be highly waterproof, able to cope with long-term rainfall, water accumulation and other situations, and remain dry in high humidity and extreme precipitation environments.
3. Wind resistance: photovoltaic roofs are often exposed to strong wind environments, so waterproof tiles must have strong wind resistance, be able to withstand damage caused by strong winds, and prevent tiles from being lifted or displaced by the wind.
4. Corrosion resistance: photovoltaic roofs are installed outdoors, especially in areas with more acid rain or in salt spray environments near the sea. Tiles need to have strong corrosion resistance to prevent erosion by chemicals.
5. Good thermal insulation: Photovoltaic panels installed on the roof will generate a lot of heat, and waterproof tiles should have good thermal insulation properties to help the roof dissipate heat and maintain a comfortable temperature inside the building.
6. Strength and durability: The waterproof tiles of the photovoltaic roof need to have sufficient strength to withstand the weight of the photovoltaic equipment on the roof and the trampling of personnel during maintenance, and are not easy to break or deform during long-term use.
7. Lightweight design: Since the photovoltaic equipment itself is heavy, the waterproof tiles should be designed with lightweight materials to reduce the overall load of the roof and ensure the safety of the building structure.
8. Environmental protection and sustainability: The waterproof tile material should be as environmentally friendly as possible to reduce pollution to the environment, especially in the field of clean energy such as photovoltaics, the material selection of tiles should meet the requirements of sustainable development.
These properties combined can ensure that the photovoltaic roof works stably for a long time under various environmental conditions and effectively protect the interior of the building from the influence of the external climate.
