The quality and life of the solar panels to a great extent are determined by the materials used in their fabrication. Although, the solar panel manufacturers in China take every possible step to ensure that the best quality material is used, it is still important to know about the stuff used in solar panels fabrication. It is important to understand why a particular material is ideal and mostly used, and this is why we got you covered here!
What do we need to know?
While manufacturing the solar panel, the back- sheet layer is the most important thing. This is the layer where the solar cells are laid out. This layer or the back sheet is made of polyvinyl fluoride or PVF. The PVF is very much similar to PVC or polyvinyl chloride which is generally used in conduits and water pipes. P.V.F is used in the airplane and vehicle interiors.
History of PVF
PVF was created in the 1940s by an American chemical company which was founded way back in 1802. This company started making products based on PVF after 10 years of its invention. The brand Tedlar brand name which was registered after 20 years of the invention of PVF became the prime material for the back sheets of the solar panels.
PVF is the most widely used material today by solar panel manufacturers in China. This is because along with a reliable history it comes along with lots of benefits. Some of the many benefits of using the PVF in the back sheet of the solar panels are as follows:
The non- stick property which it comes with makes your work easy by allowing the easy cleaning of solar panels. There are no complex processes as the dust and dirt which sticks to it is rarely a permanent one. So, using this material to make the back sheet of the panel is a choice to be made.
The PVF unlike the other materials used for making the solar panels is weather resistant and doesn’t let water to penetrate the cells. This property keeps the panels safe from any severe damage. The PVF also saves the panel from the damage caused by the water vapor which tends to be get trapped in the cells easily.
PVF also has a commendable quality of being low thermal resistant. This property of PVF prevents it from letting the heat transfer to the solar cells and the layers which compose it. Lower the thermal resistance of the material is, lesser the damage is due to heat. It can bear a high temperature without transferring it to cells and causing the harm to the layers.
