Solar POE (Polyolefin Elastomer) Encapsulant is a high-performance encapsulation film used in photovoltaic (PV) modules to protect solar cells from moisture, electrical leakage, and environmental stress.
Unlike conventional EVA, POE offers superior moisture barrier properties and enhanced PID resistance, making it ideal for advanced solar technologies such as bifacial modules and high-voltage systems.
During lamination, POE forms a durable and stable protective layer that improves long-term module reliability and performance.

POE offers significantly better moisture resistance and PID protection compared to standard EVA encapsulant.
Yes, POE is highly recommended for bifacial and glass-to-glass modules due to its low moisture permeability and high durability.
Yes, POE encapsulant provides superior protection against Potential Induced Degradation (PID), especially in high-voltage systems.
Yes, POE typically costs more than EVA, but it offers higher durability and long-term performance benefits.
Yes, POE is compatible with most modern solar module lamination systems, though parameters may vary slightly from EVA.
