Crack Resistance Technology
High-Performance Composite Materials：The composite materials used in the PA219 flexible solar panel possess high flexural modulus, high flexural strength, and high impact resistance. High flexural modulus means the material is not easily deformed when bent; high flexural strength means the material can withstand greater bending force without breaking; and high impact resistance can effectively resist external impacts, such as accidental collisions or hail impact. These properties work together to effectively reduce the risk of micro-cracks caused by bending or impact.
Optimized Structural Design: The PA219 flexible solar panel adopts a symmetrical module structure design to ensure uniform stress on the cells when the module is bent or deformed, avoiding stress concentration. Stress concentration is one of the main causes of micro-cracks. The symmetrical design minimizes the possibility of excessive local stress on the cells, thereby effectively preventing the occurrence of micro-cracks.
Fire Safety Technology
High-Performance Flame-Retardant Materials: The PA219 flexible solar panel incorporates flame-retardant polymer composite materials enhanced with specialized flame-retardant additives. These materials provide the module with superior fire performance, effectively mitigating fire hazards.
Stringent Fire Testing and Certification: The PA219 flexible solar panel’s fire safety performance complies with IEC 61730-2 standards and has successfully undergone Class A flame spread and Class C fire rating tests. These results validate the module’s exceptional ability to inhibit flame propagation and control combustion.
PID Resistance Performance
Innovative Material and Structural Design: The PA219 flexible solar power panel utilizes polymer composite materials and a frameless design, replacing the traditional glass and aluminum frame structure. This unique combination of materials and structure provides the module with excellent PID resistance.
Certification by Authoritative Institutions: The PID resistance of the PA219 flexible solar power panel has been tested by the professional institution IEC, fully demonstrating its reliability in resisting potential-induced degradation.
Dual Certification: Quality Assured
TÜV: Rigorous Testing, Assured Quality：TÜV certification is renowned for its stringent testing standards, covering safety, mechanical performance, and performance under extreme environmental conditions. These tests ensure consistent high-quality performance, providing strong assurance of product quality.
CSA: Authoritative Compliance for North America : CSA is a recognized authoritative certification in the North American market, ensuring products meet local safety, performance, and environmental regulations, making it a key enabler for market access.
