Solar Panel Outer Film material ETFE Solar Film

Solar Panel Outer Film material ETFE Solar Film

     ETFE (Vinyltetrafluoroethylene copolymer) is a high performance polymer material with outstanding physical and chemical properties. In the manufacture of solar panels, ETFE is widely used in the outer film material of solar panels.
  Solar panel production process
The general laminated solar panel structure is tempered glass /PET/ETFE+EVA+ battery +EVA+ back material
Comparison of different production processes
Glass is mainly used in large panels of photovoltaic power stations, with high structural and stability, but it is not suitable for mobile solar panels, heavy weight, not convenient to carry.
  PET and ETFE are both lighter, but ETFE is lighter than PET, which can reduce the weight of solar panels and the cost of manufacturing and transportation. Therefore, they are more commonly used in the production of portable solar panels. The light transmittance of PET is not as high as ETFE, so it is better than ETFE in cost performance.
  ETFE is anti-fouling and "self-cleaning".
Since it has a non-adhesive surface, dust and dirt in contact with the surface can easily be washed away during rainfall. This means that solar panels require less maintenance than non-ETfE panels because they don't need regular cleaning for optimal performance.
ETFE's flexible properties also help make flexible solar panels.
Flexible solar panels are much easier to install, and they can be used in many more applications than traditional fixed glass solar panels.
ETFE is made from sustainable materials that are easy to recycle at the end of a solar panel's useful life.
In addition, ETFE is a very light material, so transportation creates a much lower carbon footprint than alternative materials such as glass.
Advantages of ETFE:
ETFE has many advantages over traditional solar cells.
First, it is lighter, reducing the weight of solar panels and the cost of manufacturing and shipping them. Therefore, solar panels made from it are more portable and easy to carry, suitable for outdoor activities and field work.
    Secondly, ETFE material has relatively high light transmittance, which can allow more solar panels, thus improving the energy conversion efficiency of solar panels. In addition, ETFE material also has excellent corrosion resistance, can be used in strong acid, alkali and other environments. Therefore, ETFE materials are widely used in the manufacturing of solar panels, such as the cover plate, frame and back plate of solar panels.
Finally, ETFE material has good impact resistance and heat resistance. At different temperatures, ETFE material will not be destroyed, thus greatly increasing the lifespan of solar panels. As a result, solar panels made with ETFE can maintain them at high temperatures
