Introduction

The Lucky KPCw1 Solar Backsheet represents a significant advancement in photovoltaic (PV) module technology. Designed to withstand extreme environmental conditions, this product ensures long-term performance and reliability for solar power systems. As the demand for renewable energy grows, the importance of high-quality solar backsheets cannot be overstated. This article delves into the features, advantages, technical specifications, and applications of the Lucky KPCw1, while highlighting the expertise of its manufacturer, Baoding Lekai International Ltd..

Outstanding Environmental Resistance

The Lucky KPCw1 Solar Backsheet is engineered with a PVDF fluoropolymer weather-resistant layer that provides exceptional protection against environmental stressors. This layer is critical in maintaining the integrity of PV modules, especially in harsh climates.

UV Protection

The product boasts a UV blocking rate of over 95%, effectively preventing degradation caused by prolonged exposure to sunlight. This feature is crucial for maintaining the efficiency of solar panels over their operational lifespan.

Temperature Adaptability

Designed to function reliably in extreme temperature ranges, the KPCw1 operates efficiently between -40°C and 85°C. This adaptability makes it suitable for diverse geographical locations, from arid deserts to cold coastal regions.

Weather Durability

Passed the rigorous 3000-hour dual 85 (85°C/85% RH) aging test, the KPCw1 demonstrates its ability to endure prolonged exposure to high humidity and temperature. This test is a standard benchmark for evaluating the longevity of solar backsheet materials.

Chemical Resistance

The backsheet effectively resists acids, alkalis, solvents, and salt spray. This resistance is vital for installations in coastal areas or industrial zones where chemical exposure is common.

Mechanical Properties

After damp heat aging, the KPCw1 retains over 90% of its tensile strength, ensuring structural integrity under mechanical stress. This resilience is essential for maintaining the performance of solar modules in challenging environments.

Reliable Bonding System

The KPCw1’s fluorinated coating cured adhesive layer ensures a robust bond with EVA (ethylene-vinyl acetate) encapsulants, a critical component in PV module assembly. This bonding system has been rigorously tested to guarantee long-term reliability.

Peel Strength

With a peel strength of over 60 N/cm, the KPCw1 ensures a secure bond between the backsheet and EVA, preventing delamination and maintaining the module’s structural integrity.

Interface Stability

Thermal aging tests have demonstrated the product’s excellent interface stability, ensuring that the bond remains intact even after prolonged exposure to high temperatures.

Delamination Resistance

The KPCw1 passes thermal cycling tests without delamination, a critical factor in maintaining the performance of solar modules in regions with extreme temperature fluctuations.

UV Accelerated Aging Test

It successfully withstands 200 kWh/m² of UV accelerated aging, a testament to its durability under intense sunlight conditions.

Bond Strength Retention

In humid environments, the KPCw1 retains over 85% of its bond strength, ensuring reliable performance in high-moisture regions.

Strict Quality Control

Baoding Lekai International Ltd. employs stringent quality control measures to ensure the KPCw1 meets the highest standards of performance and reliability. Every batch undergoes a series of tests to guarantee consistency and excellence.
