The place of EVA encapsulants in solar panels

EVA encapsulants play a vital role in solar panels.
First of all, it acts as a seal and protection. Solar panels are used outdoors for a long time and face various harsh environments, such as rain, sandstorm, ultraviolet rays, etc. EVA encapsulant film can tightly wrap the cell to form a sealed environment, prevent moisture and impurities from entering, effectively protect the cell from corrosion and damage, and prolong the service life of the battery plate.
Secondly, EVA encapsulant film helps to improve the photoelectric conversion efficiency of solar panels. It has good light transmittance, which allows most of the sunlight to pass through and shine on the cell, reducing light loss. At the same time, its adhesive properties can make the cell tightly combine with the glass and backsheet, reduce the gap and air layer between the cells, reduce the thermal resistance and resistance, and improve the current transmission efficiency, thereby improving the photoelectric conversion efficiency of the entire solar panel.
In addition, EVA encapsulants have certain mechanical strength and flexibility. It can withstand certain external impact and deformation, and is not easy to break or damage during installation and use, which ensures the stability and reliability of solar panels.
In conclusion, EVA encapsulant film is an integral part of solar panels and has an important impact on the performance, lifespan and reliability of solar panels.
