Introduction to the Lucky KPCW1 Solar Backsheet

The Lucky KPCW1 Solar Backsheet represents a significant advancement in photovoltaic technology, designed to withstand the harshest environmental conditions while maintaining optimal performance. Developed by Baoding Lekai International Ltd. (保定乐凯进出口贸易有限公司), this backsheet is engineered to meet the demanding requirements of modern solar power systems. With its exceptional environmental resistance, reliable bonding system, and strict quality control measures, the KPCW1 is a preferred choice for utility-scale solar farms, commercial projects, and installations in extreme climates.

Outstanding Environmental Resistance

The KPCW1 solar backsheet is equipped with a PVDF fluoropolymer weather-resistant layer that provides comprehensive protection against environmental stressors. This advanced material formulation ensures long-term durability and performance in challenging conditions:

• UV Protection: The backsheet blocks over 95% of ultraviolet radiation, preventing degradation of the PV module’s encapsulant and ensuring consistent energy output.
• Temperature Adaptability: It maintains stable performance across a wide temperature range, from -40°C to 85°C, making it suitable for both arctic and desert environments.
• Weather Durability: The material passes a 3000-hour dual 85 (85°C/85% RH) aging test, demonstrating exceptional resistance to moisture and thermal stress.
• Chemical Resistance: The backsheet effectively withstands exposure to acids, alkalis, solvents, and salt spray, which is critical for coastal and industrial applications.
• Mechanical Properties: After damp heat aging, the material retains over 90% of its tensile strength, ensuring structural integrity under prolonged stress.

Reliable Bonding System

The KPCW1’s fluorinated coating cured adhesive layer ensures a robust bond between the backsheet and the PV module’s encapsulant. This system has been extensively tested to guarantee long-term reliability:

• Peel Strength: The bond strength with EVA (ethylene-vinyl acetate) exceeds 60 N/cm, minimizing the risk of delamination over time.
• Interface Stability: Thermal aging tests confirm the backsheet’s ability to maintain a stable interface under extreme temperature fluctuations.
• Thermal Cycling Resistance: The material shows no signs of delamination after repeated thermal cycling tests, ensuring consistent performance in variable climates.
• UV Aging Resistance: The backsheet passes a 200 kWh/m² UV accelerated aging test, simulating decades of sunlight exposure.
• Humidity Resistance: It retains over 85% of its bond strength in humid environments, a critical factor for tropical and coastal regions.

Strict Quality Control Measures

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

• Raw Material Inspection: All raw materials undergo rigorous testing to verify compliance with specifications.
• Production Monitoring: Key production parameters are monitored in real time to maintain consistency.
• Appearance and Dimensional Checks: Every finished product is inspected for visual defects and dimensional accuracy.
• Accelerated Aging Tests: Regular sampling is conducted to simulate long-term performance under accelerated conditions.
• Traceability Records: Complete documentation ensures full traceability of each batch, enabling swift identification of any issues.

These measures ensure that the KPCW1 consistently delivers the performance and reliability required for critical solar applications.

Wide Range of Applications

The KPCW1 solar backsheet is designed for diverse environments and project types, including:

• Utility-Scale Solar Power Plants: Ideal for large installations requiring long-term durability and performance.
• Commercial and Industrial Distributed Projects: Suitable for rooftops and ground-mounted systems in urban and industrial areas.
• Coastal Areas with High Humidity: Resists salt spray and moisture, making it perfect for seaside installations.
• High-Irradiation Desert Regions: Maintains stability under intense sunlight and extreme temperatures.
• Regions with Large Temperature Variations: Functions reliably in climates with significant day-to-night temperature swings.

By addressing the unique challenges of these environments, the KPCW1 ensures optimal energy output and system longevity.
