Functions of Solar EPE Encapsulant for Reliable Performance
Solar panels are built to last outside for twenty-five years or more. They stay on roofs and in fields through hot summers and freezing winters. To stay working well, the delicate solar cells inside must be protected from the environment. This is where the functions of solar EPE encapsulant become very important. This material acts as a shield and a glue, keeping the panel together and safe from damage. What Is Solar EPE Encapsulant? An EPE encapsulant is a special film used to wrap solar cells. It is made of three layers. The outer layers are made of EVA (Ethylene Vinyl Acetate) and the middle layer is made of POE (Polyolefin Elastomer) . This combination creates the EPE Solar film that many modern panel makers prefer. It is like a protective sandwich that surrounds the solar cells. This material is placed between the glass on the front and the backsheet on the rear. During the making of the panel, heat is used to melt the film. This helps the solar encapsulant protect solar pa...
