what is the main function of solar eva film?

Guangzhou Zanchen New Material Technology Co., Ltd.


Protect the battery sheet: sealing film covers the upper and lower surfaces of the battery sheet to protect the battery sheet from the influence of the external environment, such as ultraviolet radiation, temperature changes and mechanical damage.

Improve light transmittance: Sealer film has high transparency, which can maximise the sunlight to pass through and reach the battery cell, thus improving the power generation efficiency of PV module.

To provide bonding: sealing film as a bonding material, the photovoltaic module in the glass, the cell and the backplane closely together to ensure the structural stability of the module.

To extend the service life: the quality of the sealing film is directly related to the reliability and service life of the PV module, high-quality sealing film can effectively extend the service life of the module and reduce maintenance costs.

Physical isolation and heat dissipation: solar eva film provides support for the battery line, physically isolates the battery sheet and line, while conducting the heat generated by the battery sheet, maintaining the stable working temperature of the battery sheet.

Blocking water vapour: the film has excellent water vapour blocking properties, slowing down the corrosion process accelerated by environmental factors, thus prolonging the service life of photovoltaic modules.

To sum up, solar eva film plays a vital role in PV modules, not only protecting the battery sheet, but also ensuring the maximum absorption of light and the structural integrity of the components, thus guaranteeing the long-term stable operation of PV modules.
