The Lucky KPCW1 Solar Backsheet represents a significant advancement in photovoltaic (PV) technology, offering unparalleled environmental resistance and a robust bonding system. Developed by Baoding Lekai International Ltd. (Lucky International), this product is designed to meet the stringent demands of diverse solar power applications, from utility-scale projects to coastal and desert environments.
Key Features and Technological Innovations
Superior Environmental Resistance
The KPCW1 backsheet is engineered with a PVDF fluoropolymer weather-resistant layer, which provides multiple protective characteristics critical for long-term performance in harsh conditions. Key features include:
- UV Protection: Achieves over 95% UV blocking rate, preventing degradation from prolonged sunlight exposure.
- Temperature Adaptability: Maintains stable performance across a wide range of temperatures, from -40°C to 85°C.
- Weather Durability: Passes the 3000-hour dual 85 (85°C/85% RH) aging test, ensuring longevity in high-humidity environments.
- Chemical Resistance: Effectively withstands acids, alkalis, solvents, and salt spray, making it ideal for coastal regions.
- Mechanical Properties: Retains over 90% tensile strength after damp heat aging, ensuring structural integrity under stress.
These attributes are validated through rigorous testing, aligning with industry standards for solar module durability. National Institute of Standards and Technology (NIST) research underscores the importance of such materials in enhancing the efficiency and lifespan of solar panels, as highlighted in their technical publications.
Reliable Bonding System
The fluorinated coating cured adhesive layer of the KPCW1 backsheet has been extensively tested to ensure long-term reliability. Key performance metrics include:
- Peel Strength: Exceeds 60 N/cm with EVA, ensuring strong adhesion to encapsulants.
- Interface Stability: Demonstrated through thermal aging tests, maintaining compatibility with PV modules.
- Delamination Resistance: No delamination observed after thermal cycling tests, even under extreme conditions.
- UV Resistance: Passes 200 kWh/m² UV accelerated aging tests, preventing yellowing or cracking.
- Humidity Resistance: Retains over 85% bond strength in humid environments, critical for tropical and coastal regions.
These properties are crucial for maintaining the integrity of solar modules, as noted in NIST‘s guidelines for photovoltaic material performance.
Strict Quality Control
Every batch of KPCW1 backsheet undergoes meticulous quality assurance processes, including:
- Comprehensive raw material inspection to ensure consistency and purity.
- Real-time monitoring of production parameters for precision.
- 100% finished product inspection for appearance and dimensional accuracy.
- Regular sampling for accelerated aging tests to simulate long-term performance.
- Complete traceability records for accountability and continuous improvement.
This commitment to quality is reflected in the product’s reliability, as emphasized by NIST in its standards for manufacturing excellence.
