1. Introduction of Super Anti-PID EVA Film (S-Series) for PV Module Encapsulation |
As an important part of PV module, BBetter EVA film can protect the capability of solar cell from negative effect and damage of external environment.
The Potential Induced Degradation (PID) of solar module in system may cause severe power loss of PV module. Bbetter® S-series EVA film has stronger PID resistance ability, higher volume resistance than other EVA film, results in superior performance in PID test. It provides unique anti-oxidant and ion-barrier property under humidity environments. Bbetter® S-series products could withstand 96h PID test at the test condition of Temp 85℃, RH 85%, -1500Vdc.
2. Specification of Super Anti-PID EVA Film (S-Series) for PV Module Encapsulation |
- 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.
