Products Description
R2320 is an epoxy functionalized EVA anti-PID additive.
The epoxy-functionalized EVA anti-PID additive is a sophisticated formulation that is integrated into EVA films used in PV modules. This additive uses epoxy functional groups to stabilize the film and prevent electrical leakage, which leads to PID. By incorporating this chemical into the EVA encapsulant, PV module manufacturers can greatly lower the risk of PID and ensure more consistent long-term performance of their solar cells.
The epoxy-functionalized EVA anti-PID additive represents a significant achievement in the field of solar energy. By successfully minimizing PID, this additive improves PV module durability, performance, and dependability. Its unique qualities, including as better electrical insulation, thermal and UV stability, and mechanical strength, make it a critical component in high-performance solar panels. As the solar industry expands and evolves, the epoxy-functionalized anti-PID additive emerges as an essential option for assuring the long-term success and efficiency of photovoltaic systems.

This additive effectively combats PID. By integrating epoxy functional groups, the additive produces a more stable encapsulation layer that resists the electrical currents that generate PID. This guarantees that the PV modules remain efficient over time.
- Enhanced Electrical Insulation: The additive improves the EVA film’s electrical insulation qualities. This decreases the possibility of an electrical leak, which is a major cause of PID. The improved insulation means that the solar cells are more resistant to electrical stress.
- Thermal and UV Stability: In addition to PID reduction, the epoxy-functionalized additive improves the thermal and UV stability of the EVA film. This guarantees that the encapsulant retains its protective characteristics despite prolonged exposure to sunlight and fluctuating temperatures, which are frequent in outdoor solar installations.
- Mechanical Strength: The additive enhances the mechanical qualities of the EVA film. Reinforcing the film makes it more resistant to mechanical loads like stretching, ripping, and impact, increasing the overall durability of the PV modules.
- Compatibility and Processability: The additive is designed to be easily integrated and works well with typical EVA formulations and processing procedures. This ensures that manufacturers can use the additive without making significant adjustments to their current production methods.
Advantage
Extended Module Lifespan: By reducing PID, the additive considerably increases the operational life of PV modules. This minimizes the frequency of replacements and maintenance, lowering the lifecycle costs of solar energy systems.
Maintained Power Output: The anti-PID additive ensures that PV modules’ power output remains constant throughout time. The addition contributes to the maintenance of the efficiency and performance of solar panels by reducing PID-induced degradation.
Cost-Effective Solution: Incorporating the anti-PID additive into EVA films is a more cost-effective method than losing performance due to PID-induced deterioration. This additive provides a high ROI by keeping the functionality and efficiency of PV modules.
Versatility: The epoxy-functionalized additive is suited for a wide range of PV modules, including monocrystalline, polycrystalline, and thin-film technologies. Its adaptability makes it an excellent choice for a variety of solar applications.
Environmental and Safety Compliance: The additive components meet worldwide environmental and safety requirements. This assures that the product is safe to use and does not release dangerous chemicals into the environment.

Application Industry
Solar Panel Manufacturing: The anti-PID additive is primarily used in the manufacture of solar panels. Manufacturers can build PID-resistant PV modules by putting this chemical into the EVA encapsulant.
Utility-scale solar farms require PV modules that can provide continuous performance over several years. The anti-PID additive contributes to the reliability and efficiency of the modules utilized in these large-scale systems.
Residential and Commercial Solar Systems: The anti-PID additive improves the longevity and performance of solar installations. Homeowners and businesses can enjoy consistent energy generation with no upkeep.
Building-Integrated Photovoltaics (BIPV) systems, which incorporate solar panels into building structures, necessitate high-performance PV modules that can tolerate environmental stress. The additive’s PID mitigation and increased stability are very useful in these applications.
Off-Grid Solar Systems: Solar system reliability is crucial in distant and off-grid environments. The anti-PID additive ensures that off-grid solar installations remain efficient and require minimal maintenance.
