As the demand for sustainable energy solutions grows, the role of high-quality solar backsheets in ensuring the longevity and efficiency of PV modules becomes increasingly critical. This article explores the advanced features, technical specifications, and applications of the KPCw1 backsheet, while highlighting the expertise of its manufacturer, Baoding Lekai International Ltd..
Key Features of the Lucky KPCw1 Solar Backsheet
The Lucky KPCw1 Solar Backsheet is engineered with a PVDF fluoropolymer weather-resistant layer, delivering a suite of protective properties tailored for the harshest environments. These features ensure the backsheet maintains its structural integrity and performance over decades of use.
Outstanding Environmental Resistance
The PVDF fluoropolymer layer of the KPCw1 backsheet provides unparalleled protection against environmental stressors. Key advantages include:
- UV Protection: The specialized formulation achieves a UV blocking rate of over 95%, preventing degradation from prolonged sunlight exposure. This is critical for maintaining the electrical and mechanical properties of PV modules in high-irradiation regions.
- Temperature Adaptability: The backsheet operates reliably in extreme temperatures, from -40°C to 85°C. This broad range ensures performance in both arid deserts and cold climates, making it ideal for global deployment.
- Weather Durability: The product passes the 3000-hour dual 85 (85°C/85% RH) aging test, a stringent benchmark for long-term weather resistance. This certification underscores its suitability for coastal and humid environments.
- Chemical Resistance: The fluoropolymer layer effectively withstands acids, alkalis, solvents, and salt spray, safeguarding the backsheet from corrosion and chemical damage in industrial or marine settings.
- Mechanical Properties: After damp heat aging, the backsheet retains over 90% of its tensile strength, ensuring structural stability under prolonged exposure to moisture and thermal cycling.

Reliable Bonding System
The KPCw1 backsheet incorporates a fluorinated coating cured adhesive layer, ensuring a robust bond with PV modules. This system has been rigorously tested to guarantee long-term reliability:
- Peel Strength: The backsheet achieves a peel strength of over 60N/cm with EVA (ethylene-vinyl acetate), a critical factor for maintaining adhesion in high-stress conditions.
- Interface Stability: Thermal aging tests confirm the backsheet’s ability to maintain a stable interface, preventing delamination and ensuring consistent performance.
- Thermal Cycling: The product shows no delamination after thermal cycling tests, a testament to its durability in regions with significant temperature fluctuations.
- UV Accelerated Aging: The backsheet passes the 200kWh/m² UV accelerated aging test, simulating years of sunlight exposure in a controlled environment.
- Humid Environment Performance: Over 85% of bond strength is retained in humid conditions, ensuring reliability in tropical or coastal areas.
