Roof insulation sandwich panel for solar photovoltaic system

1.Panel type instruction:


The roofing panel for photovoltaic system is made of high-quality brand steel sheets for the surface,and it's continuously cold-formed and profiled.This new heat-insulating and flame-retardant material is made of D-BASF material and it is a multifunctional roofing product integrating heat preservation,energy saving and solar energy utilization.The roof rib can be directly connected with the clamp,without penetrating the roof structure.It is suitable for industrial buildings with a roof inclination of 3%.The self-cleaning high-grade panel reduces the amount of dust on the roof and keeps the building roof for a long time.Self-cleaning performance provides a systematic solution for the use of roofing solar energy.

Up to transportable length

2.Panel features:

☆ Compared with ordinary corrugated metal roofing,this roof sandwich panel improves energy and heat insulation performance of roof system.And it can perfectly attach to solar panels,which creates one green roof.


☆ Because this roof panel has 4 ribs,it improves the load carrying capacity of the roofing system and can meet the needs of photovoltaic maintenance bearings.


☆ It’s around 8cm distance between the photovoltaic panel and the roof panel,this is to ensure the ventilation of the photovoltaic cell.In this way, it can solve the problem of cooling of the photovoltaic cell, and improve the photoelectric conversion rate.

☆ The core materials such as polyurethane and rock wool are effectively flame retardant, and the burning grade reaches B1 and A1 standards, which improves the fire performance of the building.


☆ With clamps to connect the roof panels and solar panels,which avoid to broken the roof panels and roof system leakage.
