What Is Lamination Solar Panel

1 compared to epoxy resin sealed solar panel the costs of pet is a bit higher.

What is lamination solar panel. Solar panel lamination ensures the longevity of the solar cells of a module as they need to be able to withstand outdoor exposure in all types of climate for periods of 25 years and more. Solar panel lamination is crucial to ensure the longevity of the solar cells of a module. They are then laminated by machine at a temperature of 135 degrees celcius which will melt the encapsulating materials together to form a watertight bond. Why we need eva films and how are they integrated into solar pv panels.

Solar panel lamination at this moment the most common way to laminate a solar panel is by using a lamination. To protect solar photovoltaic cells from adverse weather conditions these are laminated embedded between transparent eva films in a vacuum and under heat and compression with the aid of a lamination machine. When such occurs it becomes a problem for the solar panel as it permits air and moisture to find a way into the solar panel thereby causing corrosion and power failure. As solar panels are exposed and subject to various climatic impact factors the encapsulation of the solar cells through lamination is a crucial step in traditional solar pv module manufacturing.

Eva films are an essential material used for traditional solar panel lamination. Solar modules need to convert sunlight to electricity at an acceptable cost throughout their lifetime. Delamination will occur if. This is problematic for a solar panel because it allows air and moisture to creep inside which will cause corrosion and imminent failure.

Inferior plastics are used or if the thermal properties of the plastics are poorly understood so it doesn t melt to exactly the right point or the plastics or the glass are not perfectly clean and compatible or the laminating. Solar panel delamination takes place when the bond between back plastics and the front glass begin to separate.
