Developed by Baoding Lekai International Ltd., this product combines cutting-edge materials science with rigorous quality control to deliver unmatched performance in diverse environmental conditions. This article explores the technical specifications, environmental resistance, bonding system, quality assurance protocols, and real-world applications of the KPCw1 backsheet, supported by authoritative references and visual documentation.
Product Overview
The Lucky KPCw1 Solar Backsheet is engineered to protect PV modules from harsh environmental factors while maintaining optimal electrical and mechanical performance. As a solar backsheet manufacturer, Baoding Lekai International Ltd. has focused on developing materials that address the challenges of UV degradation, thermal cycling, and chemical exposure. The product’s design incorporates a PVDF fluoropolymer weather-resistant layer, ensuring durability in extreme climates. This backsheet is particularly suited for applications in coastal regions, deserts, and areas with significant temperature fluctuations.
Environmental Resistance: A Multi-Layered Defense
The KPCw1 backsheet’s environmental resistance is achieved through a specialized PVDF fluoropolymer weather-resistant layer. This material provides a comprehensive defense against various environmental stressors:
- UV Protection: The formulation blocks over 95% of ultraviolet radiation, preventing premature degradation of the PV module’s encapsulant and electrical components.
- Temperature Adaptability: The backsheet maintains stability across a wide temperature range, from -40°C to 85°C, ensuring performance in both arctic and desert conditions.
- Weather Durability: After 3000 hours of dual 85 (85°C/85% RH) aging tests, the backsheet retains its structural integrity, meeting the stringent requirements of international solar standards.
- Chemical Resistance: The material effectively withstands exposure to acids, alkalis, solvents, and salt spray, making it ideal for coastal and industrial environments.
- Mechanical Properties: With over 90% tensile strength retention after damp heat aging, the backsheet resists cracking and deformation under prolonged stress.
Reliable Bonding System: Ensuring Long-Term Performance
The KPCw1 backsheet features a fluorinated coating cured adhesive layer that ensures robust bonding with EVA (ethylene-vinyl acetate) encapsulants. Key performance metrics include:
- Peel Strength: Exceeding 60 N/cm, this ensures long-term adhesion even under thermal and mechanical stress.
- Interface Stability: Thermal aging tests confirm minimal degradation of the bond interface, maintaining electrical insulation properties.
- Delamination Resistance: The backsheet passes thermal cycling tests without signs of delamination, a critical factor in regions with extreme temperature variations.
- UV Resistance: After 200 kWh/m² of UV accelerated aging, the bond strength remains intact, preventing moisture ingress and electrical failures.
- Humidity Resistance: Over 85% of bond strength is retained in humid environments, ensuring reliability in tropical and coastal regions.
Strict Quality Control: Ensuring Consistency and Compliance
Baoding Lekai International Ltd. implements a comprehensive quality control framework to guarantee the KPCw1 backsheet meets international standards:
- Raw Material Inspection: All raw materials undergo rigorous testing for purity and consistency.
- Real-Time Monitoring: Production parameters such as temperature, pressure, and coating thickness are continuously monitored.
- Dimensional Inspection: Every finished product is inspected for dimensional accuracy and surface defects.
- Accelerated Aging Tests: Regular sampling is conducted to simulate long-term environmental exposure.
- Traceability Records: Detailed records are maintained for each batch, enabling full traceability from production to delivery.
