Designed to withstand extreme conditions, this product is ideal for a wide range of solar energy applications, from utility-scale projects to coastal and desert environments. This article delves into the product’s core features, technical specifications, and the company’s commitment to innovation.
Product Overview
The Lucky KPCw1 Solar Backsheet is engineered to provide long-term protection for PV modules, ensuring optimal performance under harsh environmental conditions. Its advanced design incorporates a PVDF fluoropolymer weather-resistant layer, a fluorinated coating adhesive, and a strict quality control system. These elements work in harmony to deliver reliability, durability, and efficiency in solar energy systems.
Environmental Resistance: A Shield Against Extreme Conditions
The KPCw1 backsheet’s primary advantage lies in its outstanding environmental resistance. The PVDF fluoropolymer weather-resistant layer is formulated to protect PV modules from UV radiation, temperature fluctuations, chemical exposure, and mechanical stress. Below are the key features:
- UV Protection: The special formulation blocks over 95% of UV radiation, preventing degradation of the PV module’s performance and lifespan.
- Temperature Adaptability: The backsheet maintains stability between -40°C and 85°C, making it suitable for both extreme cold and heat.
- Weather Durability: It passes the 3000-hour dual 85 (85°C/85% RH) aging test, ensuring long-term reliability in humid and high-temperature environments.
- Chemical Resistance: The material effectively withstands acids, alkalis, solvents, and salt spray, critical for coastal and industrial areas.
- Mechanical Properties: Retains over 90% of its tensile strength after damp heat aging, ensuring structural integrity.
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. This system has been rigorously tested to ensure:
- Peel Strength: Exceeds 60 N/cm with EVA, ensuring long-term reliability and resistance to delamination.
- Thermal Stability: Demonstrates excellent interface stability in thermal aging tests, preventing performance degradation.
- Thermal Cycling: No delamination after repeated thermal cycling tests, ensuring durability in fluctuating temperatures.
- UV Resistance: Passes the 200kWh/m² UV accelerated aging test, maintaining bond strength under prolonged sunlight exposure.
- Humidity Resistance: Retains over 85% of bond strength in humid environments, critical for tropical and coastal regions.
Strict Quality Control: Ensuring Consistency and Compliance
Every batch of the KPCw1 backsheet undergoes a comprehensive quality control process, including:
- Raw Material Inspection: Rigorous testing of raw materials to ensure compliance with industry standards.
- Production Monitoring: Real-time monitoring of key production parameters to maintain quality.
- Final Inspection: 100% inspection of appearance and dimensions for consistency.
- Accelerated Aging Tests: Regular sampling for accelerated aging tests to simulate long-term performance.
- Traceability Records: Complete documentation of product quality for traceability and accountability.
Wide Range of Applications: Versatility for Diverse Environments
The KPCw1 backsheet is designed for use in the following applications:
- Utility-Scale Solar Power Plants: Provides reliable protection for large-scale installations in diverse climates.
- Commercial and Industrial Projects: Suitable for rooftop and ground-mounted systems in urban and industrial areas.
- Coastal Areas: Resists salt spray and high humidity, making it ideal for coastal regions.
- High-Irradiation Deserts: Maintains performance under intense sunlight and extreme temperatures.
- Regions with Temperature Variations: Ensures stability in areas with significant day-night temperature swings.
