(1)Brief introduction：

　　Photovoltaic cell has been applied and assembles in energy-saving construction building. Tianfon has developed multi-functioned roofing system integrated energy-saving and insulation and solar energy utilization. T his system adopts distinguished metallic polyurethane sandwich panel as roofing support.

　　Tianfon YU panel is multi-functioned roofing system integrated insulation energy-saving and solar energy utilization and connected by clips, don’t need to wear roof structure, 100% leak proof. To provide systematic solution for roofing solar power utilization.

　　The roof panel is specially designed for photovoltaic roof system; roof crest is connected by clips. Don't need to wear roof structure, 100% leak proof. Roof panel adopts high quality steel sheet as surface material. After cold formed and injected fire-retardant polyurethane liquid, then through high pressure mixing, foaming and curing process. The core material and surface material composed together. The panel is produced by polyurethane continuous plant and standard Producing in the factory, stable product quality.

　　(2)Product characters：

　　1.Optimized energy-saving and insulation properties of polyurethane, and utilize clean solar energy which is to build green and environment friendly roofing.

　　2.Multi-waves improve the bearing capacity of roof that can meet the demand of photovoltaic repair bearing.

　　3.There is 8cm air channel between photovoltaic cells and roofing which ensure the ventilation of photovoltaic cells back and solve the problems of the photovoltaic battery cooling and improve the photoelectric conversion rate.

　　4.Clamping type wave design, with a special leather which can realize implementing modular fast installation of photovoltaic roof system;

　　5.Clamping type connection fixed way, avoid turn roof hole leakage hidden trouble
