Jwell EVA/POE Solar Film Extrusion Line
EVA/POE photovoltaic film is mainly used in the encapsulation of photovoltaic modules and is the key material of photovoltaic modules; it can also be used in various industries such as architectural glass curtain wall, automotive glass, hot melt adhesive, etc.
An automatic gravimetric feeding system makes sure a variety of solid, and liquid additives and raw materials are high-precision feeding. Low-temperature extrusion systems ensure adequate mixing in the premise of plastination to prevent cross-linking additives. The special design of the Casting part gives the perfect solution to roller adhibition and water spalling.Special online tempering device to get rid of inner stress. The tension control system ensures the flexible sheets convey placidly during the cooling, pulling, and winding process. The online thickness measuring and defect inspecting system can provide real-time feedback on the production quality of EVA/POE solar film.

EVA / POE solar films have the following important applications:
1. Photovoltaic module encapsulation
- Protection of solar cells:
- In a photovoltaic module, solar cells are very delicate. EVA/POE films act as a protective layer, shielding the cells from external factors such as moisture, dust, and mechanical damage.
- Enhancement of light transmittance:
- These films have excellent light-transmitting properties. They can effectively transmit sunlight to the solar cells with a high transmittance rate of over 90% in the visible light range. This enables solar cells to make full use of solar energy for photoelectric conversion.
- Adhesion and fixation:
- EVA/POE films have good adhesion. They can firmly adhere to the surface of solar cells and the backsheet of the photovoltaic module, keeping the internal structure of the module stable. This is crucial for the long - term operation of the photovoltaic module.
2. Flexible photovoltaic applications
- For flexible solar panels:
- POE - based films are more suitable for flexible photovoltaic devices. Due to their flexibility and good toughness, they can be used in the production of flexible solar panels. These flexible solar panels can be installed on curved surfaces such as vehicle roofs, tents, and backpacks.
3. Durability and long - term performance improvement of photovoltaic systems
- Resistance to environmental factors:
- These films have good resistance to ultraviolet (UV) radiation, temperature changes, and other environmental factors. UV radiation in sunlight can cause degradation of materials. EVA/POE films can effectively block UV rays, reducing the impact of UV radiation on the internal components of photovoltaic modules. At the same time, they can also withstand a wide range of temperature changes. In cold or hot environments, they can maintain their physical and chemical properties, ensuring the normal operation of photovoltaic modules. For example, in a desert photovoltaic power station with large temperature differences between day and night, the film can still play a good protective role.
- Extension of service life:
- By providing reliable encapsulation and protection, EVA/POE solar films can significantly extend the service life of photovoltaic modules. A well - encapsulated photovoltaic module using high - quality EVA/POE films can have a service life of more than 25 years, which is of great significance for the economic and stable operation of photovoltaic power generation systems.
