This article explores the product’s core features, technical specifications, and real-world applications, while also highlighting the company’s expertise in the solar backsheet industry.

Outstanding Environmental Resistance

The Lucky KPCw1 Solar Backsheet is engineered with a PVDF fluoropolymer weather-resistant layer that provides unmatched protection against environmental stressors. This advanced material is designed to maintain its integrity under extreme conditions, ensuring the longevity of PV modules in diverse climates.

• UV Protection: The special formulation of the PVDF layer achieves an impressive 95% UV blocking rate, preventing degradation from prolonged sunlight exposure. This is critical for maintaining the electrical performance and structural stability of solar panels over their operational lifespan.
• Temperature Adaptability: The backsheet functions reliably across a wide temperature range of -40°C to 85°C, making it suitable for deployment in both freezing and scorching environments. This adaptability ensures consistent performance in regions with extreme weather fluctuations.
• Weather Durability: The product has passed the 3000-hour dual 85 (85°C/85% RH) aging test, a stringent industry standard that simulates years of environmental exposure. This certification underscores its ability to resist moisture, heat, and mechanical stress over extended periods.
• Chemical Resistance: The PVDF layer effectively withstands exposure to acids, alkalis, solvents, and salt spray, making it ideal for coastal and industrial environments where chemical corrosion is a concern.
• Mechanical Properties: After damp heat aging tests, the backsheet retains over 90% of its tensile strength, ensuring it can endure physical stress without compromising structural integrity.

Reliable Bonding System

The Lucky KPCw1 Solar Backsheet features a fluorinated coating cured adhesive layer that ensures a robust bond between the backsheet and the PV module. This bonding system has been rigorously tested to guarantee long-term reliability under challenging conditions.

• Peel Strength: The backsheet achieves a peel strength of over 60 N/cm when bonded to EVA (ethylene-vinyl acetate), a critical parameter for maintaining adhesion in high-stress environments.
• Interface Stability: Thermal aging tests demonstrate excellent interface stability, ensuring the backsheet remains firmly attached to the module even after prolonged exposure to heat.
• Delamination Resistance: The product passes thermal cycling tests without delamination, a common failure mode in subpar backsheet materials.
• UV Resistance: The backsheet withstands 200 kWh/m² of UV accelerated aging, a testament to its ability to endure prolonged sunlight exposure without degrading.
• Humid Environments: In humid conditions, the bond strength retention exceeds 85%, ensuring the backsheet remains intact in high-moisture regions.
