The Lucky KPCw1 Solar Backsheet represents a cutting-edge advancement in photovoltaic (PV) technology, designed to address the demanding requirements of modern solar energy systems. Developed by Baoding Lekai International Ltd., this product combines superior environmental resistance, reliable bonding, and rigorous quality control to deliver exceptional performance in diverse conditions. This article explores the core features, technical specifications, application scenarios, and company background of the KPCw1 backsheet, providing a comprehensive overview for industry professionals and stakeholders.
Key Features of the Lucky KPCw1 Solar Backsheet
The KPCw1 backsheet is engineered with a PVDF fluoropolymer weather-resistant layer, which provides multiple protective characteristics critical for long-term solar panel performance:
- UV Protection: The specialized formulation achieves an impressive over 95% UV blocking rate, preventing degradation from prolonged sunlight exposure.
- Temperature Adaptability: It maintains stable performance across a wide range of temperatures, from -40°C to 85°C, making it suitable for extreme climates.
- Weather Durability: The backsheet passes a 3000-hour dual 85 (85°C/85% RH) aging test, ensuring resilience against moisture and heat.
- Chemical Resistance: It effectively withstands acids, alkalis, solvents, and salt spray, protecting panels in corrosive environments.
- Mechanical Properties: After damp heat aging, the material retains over 90% of its tensile strength, maintaining structural integrity under stress.
Complementing these features is a fluorinated coating cured adhesive layer, which has been rigorously tested for reliability:
- Peel Strength: The bond with EVA (ethylene-vinyl acetate) exceeds 60N/cm, ensuring long-term adhesion.
- Interface Stability: Thermal aging tests confirm excellent interface stability, preventing delamination.
- Thermal Cycling: No delamination occurs after thermal cycling tests, maintaining performance under temperature fluctuations.
- UV Resistance: The backsheet passes a 200kWh/m² UV accelerated aging test, simulating years of sunlight exposure.
- Humid Environments: It retains over 85% bond strength in high-humidity conditions, critical for coastal and tropical regions.

Additionally, the backsheet passes thermal cycling tests without delamination, a testament to its durability.
Every batch of KPCw1 undergoes strict quality control measures, including:
- Comprehensive raw material inspection to ensure purity and consistency.
- Real-time monitoring of key production parameters for precision.
- 100% finished product appearance and dimensional inspection for quality assurance.
- Regular sampling for accelerated aging tests to simulate long-term performance.
- Complete product quality traceability records for accountability.
Wide Range of Applications
The KPCw1 backsheet is tailored for diverse environments and project types:
- Utility-Scale Solar Power Plants: Ideal for large installations requiring high reliability and durability.
- Commercial and Industrial Distributed Projects: Suitable for rooftop and ground-mounted systems in urban and industrial areas.
- Coastal Areas with High Humidity: Its chemical resistance and humidity tolerance make it perfect for salty, humid climates.
- High-Irradiation Desert Regions: The backsheet’s UV protection and temperature adaptability ensure performance in extreme heat.
- Regions with Large Temperature Variations: It maintains stability in areas with frequent temperature swings.
These applications highlight the KPCw1’s versatility, making it a preferred choice for solar projects in challenging environments. For example, in coastal regions, the backsheet’s resistance to salt spray and humidity prevents corrosion, while in deserts, its UV blocking and thermal stability protect panels from degradation.
