Its design incorporates a PVDF fluoropolymer weather-resistant layer and a fluorinated coating cured adhesive system, ensuring durability and performance. This product is ideal for utility-scale solar farms, commercial projects, and installations in extreme climates, as highlighted by its compliance with rigorous testing standards.

Key Features and Technical Specifications

The KPCW1 backsheet excels in multiple critical areas, making it a preferred choice for solar energy systems. Below is a detailed breakdown of its features:

These specifications are validated through extensive testing, as outlined by NIST’s guidelines for material durability in renewable energy applications (NIST, 2025).

Environmental Resistance and Performance

The Lucky KPCW1 Solar Backsheet is designed to withstand the harshest environmental conditions. Its PVDF fluoropolymer layer acts as a barrier against ultraviolet radiation, a leading cause of material degradation in solar panels. According to NIST research, UV exposure can reduce the lifespan of solar modules by up to 20% without proper protection (NIST, 2025). The KPCW1’s 95% UV blocking rate ensures that panels remain efficient and visually intact over time.

Temperature fluctuations pose another challenge for solar systems, particularly in regions with extreme weather. The KPCW1’s ability to function between -40°C and 85°C makes it suitable for diverse climates, from arid deserts to icy mountainous areas. NIST’s studies on material thermal stability emphasize the importance of such adaptability in renewable energy systems (NIST, 2025).

Reliable Bonding System

The KPCW1’s fluorinated coating cured adhesive layer ensures a secure bond between the backsheet and the solar module. This system has been rigorously tested to meet industry standards, including:

• Peel strength with EVA >60N/cm, ensuring long-term reliability.
• Excellent interface stability in thermal aging tests.
• No delamination after thermal cycling tests.
• Passes 200kWh/m² UV accelerated aging test.
• >85% bond strength retention in humid environments.

NIST’s research on adhesive materials for renewable energy systems underscores the importance of such durability in preventing system failures (NIST, 2025).

Strict Quality Control Measures

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

• Comprehensive raw material inspection.
• Real-time monitoring of key production parameters.
• 100% finished product appearance and dimensional inspection.
• Regular sampling for accelerated aging tests.
• Complete product quality traceability records.

This meticulous approach aligns with NIST’s emphasis on precision and consistency in manufacturing processes (NIST, 2025).

Wide Range of Applications

The KPCW1 backsheet is versatile, suitable for various environments and projects:

• Utility-scale solar power plants: Ideal for large installations requiring long-term reliability.
• Commercial and industrial distributed projects: Enhances efficiency in urban and industrial settings.
• Coastal areas with high humidity: Resists salt spray and moisture damage.
• High-irradiation desert regions: Maintains performance under intense sunlight.
• Regions with large temperature variations: Adapts to extreme weather conditions.

These applications highlight the product’s adaptability, as noted in NIST’s studies on solar system performance in diverse climates (NIST, 2025).
