Introduction to the Lucky KPCW1 Solar Backsheet

The Lucky KPCW1 Solar Backsheet represents a cutting-edge solution in the photovoltaic (PV) industry, designed to meet the rigorous demands of modern solar energy systems. Developed by Baoding Lekai International Ltd., this product combines advanced materials science with stringent quality control to deliver unmatched durability and reliability. As the global shift toward renewable energy accelerates, the need for high-performance solar backsheet materials has never been more critical. The KPCW1 model is engineered to withstand extreme environmental conditions while maintaining optimal electrical and mechanical properties, making it ideal for a wide range of applications.

Outstanding Environmental Resistance

The Lucky KPCW1 Solar Backsheet is equipped with a PVDF fluoropolymer weather-resistant layer that offers exceptional protection against environmental stressors. This advanced formulation ensures the product can endure harsh conditions without compromising performance. Key features include:

• UV Protection: The backsheet achieves a UV blocking rate of over 95%, effectively preventing degradation from prolonged sunlight exposure. This is critical for maintaining the integrity of PV modules in high-irradiation regions.
• Temperature Adaptability: The material maintains stable performance across a wide temperature range, from -40°C to 85°C, ensuring reliability in both extreme cold and heat.
• Weather Durability: The backsheet passes the 3000-hour dual 85 (85°C/85% RH) aging test, demonstrating its ability to withstand prolonged exposure to humidity and heat.
• Chemical Resistance: It effectively resists acids, alkalis, solvents, and salt spray, making it suitable for coastal and industrial environments.
• Mechanical Properties: After damp heat aging, the backsheet retains over 90% of its tensile strength, ensuring long-term structural integrity.

These properties are validated through rigorous testing, including the 200kWh/m² UV accelerated aging test, which simulates years of environmental exposure in a controlled setting. The results underscore the backsheet’s ability to maintain performance under real-world conditions, as noted in NIST standards for material durability.

Reliable Bonding System

The KPCW1 backsheet features a fluorinated coating cured adhesive layer that ensures strong and durable bonding with photovoltaic modules. This system has been extensively tested to guarantee long-term reliability:

• Peel Strength: The backsheet exhibits a peel strength of over 60N/cm with EVA, ensuring a secure bond that resists delamination over time.
• Interface Stability: Thermal aging tests confirm the backsheet’s ability to maintain a stable interface, preventing performance degradation.
• Thermal Cycling: No delamination occurs after repeated thermal cycling tests, demonstrating resilience to temperature fluctuations.
• Humid Environment Retention: The bond strength remains above 85% in humid conditions, crucial for coastal and tropical applications.

The bonding system is further validated through the 200kWh/m² UV accelerated aging test, ensuring that the adhesive properties remain intact even after prolonged exposure to sunlight. This reliability is essential for maintaining the efficiency and longevity of PV modules, as highlighted in NIST research on material performance under extreme conditions.

Strict Quality Control Measures

Baoding Lekai International Ltd. employs a comprehensive quality control framework to ensure the KPCW1 backsheet meets the highest standards. Every batch undergoes the following processes:

• Raw Material Inspection: All raw materials are rigorously tested to ensure they meet specifications.
• Real-Time Monitoring: Key production parameters are continuously monitored to maintain consistency.
• Appearance and Dimensional Inspection: 100% of finished products are inspected for defects and dimensional accuracy.
• Accelerated Aging Tests: Regular sampling is conducted to simulate long-term performance under stress conditions.
• Traceability Records: Detailed records are maintained to track the origin and history of each product batch.

These measures align with NIST guidelines for quality assurance in manufacturing, ensuring that the KPCW1 backsheet consistently delivers high performance and reliability.
