The Lucky KPCw1 Solar Backsheet is a cutting-edge solution designed to enhance the durability and efficiency of photovoltaic (PV) modules. As the renewable energy sector continues to expand, the demand for high-performance solar backsheet materials has never been higher. This article delves into the technical specifications, environmental resistance, bonding system, quality control measures, and application scenarios of the KPCw1 model, while also highlighting the expertise of its manufacturer, Baoding Lekai International Ltd..
Environmental Resistance: A Shield Against Harsh Conditions
The KPCw1 solar backsheet is engineered to withstand extreme environmental conditions, making it ideal for diverse geographical and climatic zones. At the core of its design is a PVDF fluoropolymer weather-resistant layer, which provides multi-layered protection against UV radiation, temperature fluctuations, and chemical exposure.
- UV Protection: The special formulation blocks over 95% of UV radiation, preventing degradation and maintaining the integrity of the PV module.
- Temperature Adaptability: The backsheet operates effectively between -40°C and 85°C, ensuring stability in both freezing and scorching environments.
- Weather Durability: It passes the rigorous 3000-hour dual 85 (85°C/85% RH) aging test, a benchmark for long-term reliability.
- Chemical Resistance: The material resists acids, alkalis, solvents, and salt spray, making it suitable for coastal and industrial areas.
- Mechanical Properties: After damp heat aging, the backsheet retains over 90% of its tensile strength, ensuring structural resilience.

Reliable Bonding System: Ensuring Long-Term Performance
The KPCw1’s fluorinated coating cured adhesive layer is designed to maintain strong adhesion between the backsheet and the PV module components. This system has been rigorously tested to ensure long-term reliability:
- Peel Strength: Exceeds 60N/cm with EVA, preventing delamination under stress.
- Thermal Aging Stability: Demonstrates excellent interface stability after prolonged exposure to heat.
- Thermal Cycling Resistance: No delamination occurs after repeated temperature cycles.
- UV Resistance: Survives 200kWh/m² of UV accelerated aging, meeting industry standards.
- Humid Environments: Retains over 85% bond strength in high-humidity conditions.
