Key Features of the Lucky KPCw1 Solar Backsheet
Outstanding Environmental Resistance
The KPCw1 backsheet is engineered with a polyvinylidene fluoride (PVDF) fluoropolymer weather-resistant layer, designed to withstand extreme environmental conditions. This layer provides:
- UV Protection: Over 95% UV blocking rate to prevent degradation from sunlight exposure.
- Temperature Adaptability: Maintains performance between -40°C and 85°C, ensuring reliability in both freezing and scorching climates.
- Weather Durability: Passes 3000-hour dual 85 (85°C/85% RH) aging tests, demonstrating exceptional longevity.
- Chemical Resistance: Resists acids, alkalis, solvents, and salt spray, ideal for coastal and industrial environments.
- Mechanical Properties: Retains over 90% tensile strength after damp heat aging, ensuring structural integrity under stress.
These features align with NIST’s emphasis on standards for material durability in renewable energy systems, as highlighted in their research on photovoltaic material testing.
Reliable Bonding System
The backsheet incorporates a fluorinated coating cured adhesive layer that ensures long-term performance. Key metrics include:
- Peel Strength: Exceeds 60N/cm with EVA, ensuring robust adhesion to PV modules.
- Interface Stability: Demonstrated through thermal aging tests, maintaining bond integrity under extreme temperatures.
- Delamination Resistance: No delamination observed after thermal cycling tests, a critical factor for solar panel longevity.
- UV Resistance: Survives 200kWh/m² UV accelerated aging tests, meeting industry benchmarks.
- Humidity Resistance: Retains over 85% bond strength in humid environments, crucial for tropical and coastal regions.
These specifications reflect NIST’s guidelines for adhesive performance in photovoltaic applications, as outlined in their standards for material adhesion testing.
