Product Advantage
Convenient Installation: Due to the pre-reserved installation positions for photovoltaic components, the installation time of the photovoltaic roof system can be greatly shortened. Installation personnel only need to fix the photovoltaic components according to the reserved positions, reducing cumbersome steps such as on - site measurement, marking, and drilling. Compared with traditional roof sandwich panels that require temporary planning of photovoltaic installation positions, the installation efficiency can be increased by about 30% - 50%.
High Stability: The reserved installation positions can ensure perfect adaptation between the photovoltaic components and the sandwich panel, improving the overall stability of the photovoltaic system. After installation, the photovoltaic components can closely adhere to the surface of the sandwich panel, avoiding problems such as component loosening and tilting caused by non - standard installation, thereby ensuring the power generation efficiency and service life of the photovoltaic system.
High Strength: The unique structural design endows the sandwich panel with relatively high structural strength. It can bear multiple loads, including wind load, snow load, and the loads generated by roof equipment and personnel activities. Even if photovoltaic components are added to the roof, the requirement of no deformation can be met.
High - Efficiency Thermal Insulation: PU/PUR/PIR has a low thermal conductivity, which can make the indoor temperature more stable. In summer, it can prevent external heat from entering the room, reducing the frequency of air - conditioner use; in winter, it can prevent indoor heat from dissipating outdoors, reducing heating costs. Taking a 1,000 - square - meter building as an example, after using the metal - faced photovoltaic roof sandwich panel, the annual heating and cooling energy consumption can be reduced by about 20% - 30%. At the same time, combined with photovoltaic components, the energy - saving effect of the building is further enhanced. Photovoltaic components generate electricity using solar energy, reducing the building's dependence on traditional energy sources; while the thermal insulation function of the sandwich panel reduces the internal energy consumption of the building, and the two complement each other to jointly achieve high - efficiency energy - saving in the building.
