The Lucky KPCw1 Solar Backsheet represents a significant advancement in photovoltaic (PV) technology, offering unmatched environmental resistance, reliable bonding, and rigorous quality control. As a leading solar backsheet manufacturer, Baoding Lekai International Ltd. has engineered this product to meet the demanding requirements of modern solar energy systems. This article provides an in-depth analysis of the KPCw1’s features, technical specifications, application scenarios, and the company’s commitment to innovation.
Key Features of the Lucky KPCw1 Solar Backsheet
The KPCw1 is designed to withstand extreme environmental conditions, making it ideal for diverse geographical locations. Its core features include:
- Outstanding Environmental Resistance: The PVDF fluoropolymer weather-resistant layer provides comprehensive protection against UV radiation, temperature fluctuations, and chemical exposure.
- Reliable Bonding System: The fluorinated coating cured adhesive layer ensures long-term durability and stability in challenging conditions.
- Strict Quality Control: Every batch undergoes rigorous testing to guarantee performance and consistency.
Environmental Resistance: A Shield Against Harsh Conditions
The KPCw1’s UV protection is a standout feature, with a special formulation that achieves over 95% UV blocking. This is critical for maintaining the integrity of PV modules in regions with high solar irradiation. The backsheet also demonstrates exceptional temperature adaptability, operating effectively from -40°C to 85°C. This makes it suitable for both arctic and desert environments.
Another key aspect is its weather durability, having passed the 3000-hour dual 85 (85°C/85% RH) aging test. This rigorous testing ensures the product can withstand prolonged exposure to humidity and heat. Additionally, the chemical resistance of the KPCw1 allows it to endure acids, alkalis, solvents, and salt spray, making it ideal for coastal and industrial areas.
The backsheet also maintains mechanical properties with over 90% tensile strength retention after damp heat aging, ensuring structural stability in humid conditions.
Reliable Bonding System: Ensuring Long-Term Performance
The KPCw1’s bonding system is engineered for durability. Its fluorinated coating cured adhesive layer has been tested to achieve a peel strength with EVA of over 60N/cm, ensuring secure adhesion over time. The product also demonstrates interface stability in thermal aging tests, preventing degradation under cyclic temperature changes.
Notably, the backsheet shows no delamination after thermal cycling tests, a critical factor for PV modules in regions with extreme temperature variations. It also passes the 200kWh/m² UV accelerated aging test, confirming its resilience to prolonged sunlight exposure. In humid environments, the KPCw1 retains over 85% of its bond strength, ensuring long-term reliability.
Strict Quality Control: Ensuring Consistency and Reliability
Every batch of KPCw1 undergoes a comprehensive quality assurance process. This includes raw material inspection, real-time monitoring of production parameters, and 100% finished product inspection for appearance and dimensions. Regular sampling for accelerated aging tests ensures compliance with industry standards, while complete traceability records provide transparency for customers.
