Introduction
The Lucky KPCW1 Solar Backsheet represents a significant advancement in photovoltaic (PV) technology, designed to enhance the durability and efficiency of solar panels in diverse environmental conditions. As the global demand for renewable energy grows, the need for reliable, high-performance materials becomes increasingly critical. This article explores the solar backsheet manufacturer’s innovative approach to addressing these challenges, with a focus on the KPCW1 model’s technical specifications, applications, and the company’s commitment to quality and innovation.
Outstanding Environmental Resistance
The KPCW1 solar backsheet is engineered to withstand the harshest environmental conditions, ensuring long-term performance and reliability for solar power systems. Its key features include:
- UV Protection: The PVDF fluoropolymer weather-resistant layer achieves an impressive over 95% UV blocking rate, safeguarding the underlying materials from degradation caused by prolonged exposure to sunlight.
- Temperature Adaptability: The backsheet maintains stable performance across a wide temperature range, from -40°C to 85°C, making it suitable for deployment in extreme climates.
- Weather Durability: It has passed the 3000-hour dual 85 (85°C/85% RH) aging test, demonstrating exceptional resistance to moisture and heat, which are common causes of material failure in solar panels.
- Chemical Resistance: The formulation effectively withstands exposure to acids, alkalis, solvents, and salt spray, ensuring longevity in coastal and industrial environments.
- Mechanical Properties: After damp heat aging, the backsheet retains over 90% of its tensile strength, maintaining structural integrity under mechanical stress.
These attributes are critical for ensuring the solar backsheet material can endure the rigors of outdoor installation, reducing the risk of premature failure and maintenance costs.

Reliable Bonding System
The KPCW1’s fluorinated coating cured adhesive layer is designed to ensure long-term reliability and interface stability. Key performance metrics include:
- Peel Strength: The bond with EVA (ethylene-vinyl acetate) exceeds 60N/cm, providing robust adhesion that resists delamination over time.
- Thermal Aging Tests: The bonding system demonstrates excellent interface stability under prolonged thermal stress, as confirmed by rigorous testing.
- Thermal Cycling Tests: The backsheet shows no delamination after repeated temperature fluctuations, a critical requirement for regions with extreme climate variations.
- UV Accelerated Aging: It passes the 200kWh/m² UV accelerated aging test, ensuring durability under intense sunlight exposure.
- Humid Environments: The bond strength retains over 85% of its original value in high-humidity conditions, preventing moisture ingress that could compromise panel performance.

Strict Quality Control
Baoding Lekai International Ltd. employs a comprehensive quality control framework to ensure the KPCW1 meets the highest standards. Every batch undergoes:
- Comprehensive Raw Material Inspection: All raw materials are rigorously tested for purity and consistency before production.
- Real-Time Production Monitoring: Key parameters are monitored continuously to maintain precision and uniformity.
- 100% Finished Product Inspection: Each backsheet is checked for appearance, dimensions, and surface quality.
- Accelerated Aging Tests: Regular sampling is subjected to accelerated aging to simulate long-term performance under extreme conditions.
- Traceability Records: Detailed records are maintained to ensure full traceability from raw materials to final products.
This meticulous approach ensures that the solar backsheet delivered to customers is not only high-performing but also consistently reliable.

Wide Range of Applications
The KPCW1 is designed for use in diverse environments and applications, including:
- Utility-Scale Solar Power Plants: Ideal for large-scale installations requiring long-term durability and performance.
- Commercial and Industrial Projects: Suitable for rooftops and ground-mounted systems in urban and industrial settings.
- Coastal Areas: Resists corrosion from salt spray and high humidity, making it ideal for seaside installations.
- High-Irradiation Desert Regions: Maintains performance under intense sunlight and extreme temperature fluctuations.
- Regions with Large Temperature Variations: Ensures stability in climates with significant day-night temperature swings.
As noted by the National Institute of Standards and Technology (NIST), “materials used in renewable energy systems must meet stringent standards for environmental resilience to ensure long-term reliability” (NIST, 2025). The KPCW1 aligns with these principles, offering a solution that adapts to the unique challenges of various geographic and climatic conditions.
