Encapsulants, such as EVA (ethylene-vinyl acetate), POE (polyolefin elastomer), and EPE (Co-extruded EVA/POE/EVA), serve as the essential adhesive that holds solar panels together. However, their role extends far beyond mere adhesion. An effective encapsulant must minimize resistance to light transmission to the solar cells, maximize resistance to electricity to prevent current leakages while ensuring their longevity.
The science of encapsulants is continuously evolving, with each new iteration addressing and eliminating various undesirable factors. Despite these advancements, one of the most significant challenges remains acid formation in EVA encapsulants, which can lead to the degradation of solar cells over time. RenewSys' latest EVA technology effectively mitigates this issue.
Let us explore how RenewSys has achieved this breakthrough with its innovative Anti-Acid EVA encapsulant
