The Potential Induced Degradation (PID) of solar module in system may cause severe power loss of PV system. Our EVA film provide an encapsulant solution for the PID-free requirement of PV module. Our EVA film provides excellent PID-resistance to silicon module by improving volume resistance of EVA film. it could withstand 96h PID test at the test condition of Temp 85℃, RH 85%, -1000Vdc.
Advantages:
- Excellent weather resistance, high temperature, humidity and UV resistant.
- Excellent material compatibility and matching.
- Optimum operability, easy to store, laminating with wide temperature range and high efficiency.
- Excellent anti-PID and anti-snail pattern.
- Different types of EVA film such as: High transmittance type, anti-UV type, anti-PID type, high refractive index type, anti-snail pattern type and fast solidifying type will be provided.
- BBetter film is committed to producing EVA film with world-class quality, and providing more comprehensive solutions for PV modules.
