Solar Module Monocrystalline Features
TOPCon Technology
By using N-type TOPCon cells, this module achieves higher efficiency in converting sunlight into electricity. TOPCon technology enhances photon-to-electron conversion, which leads to better performance, especially in low-light and shaded conditions, and also increases the module’s reliability while reducing power degradation over time.
Durable Glass and Frame Design
The module is equipped with high-transmittance, low-iron tempered glass that enhances durability and resistance to environmental stressors. The robust aluminum frame provides additional protection against corrosion and mechanical damage, ensuring longevity and reliability.
Monocrystalline Cells
The module uses monocrystalline cells for enhanced efficiency and a sleek appearance.
Multi-Busbar Design
The MBB (Multi-Busbar) design minimizes cell resistance and increases output power for improved efficiency and performance.
Extended Wind and Snow Load Tests
Designed to withstand harsh weather conditions, the solar panel pv module has undergone extensive wind and snow load testing. This rigorous testing guarantees that the module can endure extreme environmental stresses, making it suitable for installation in diverse geographical locations. The robust construction ensures longevity and durability, even in challenging climates.
Anti-Reflective Coating
The surface of the solar cells is treated with an anti-reflective coating that minimizes light reflection and maximizes light absorption. This feature significantly boosts the overall energy conversion efficiency of the module.
Low LID
TOPCon N-type cells have high phosphorus content and minimal boron, which reduces the impact of boron-oxygen pairs and virtually eliminates Light-Induced Degradation (LID).
Performance and Efficiency
Module Efficiency: Up to 22.65% module efficiency, which means more electricity generated per square foot.
Low-Light Performance: Excellent performance in low-light conditions, making it suitable for various environments.
Temperature Coefficient: Optimized temperature coefficient ensures stable power generation even in high-temperature climates.
Power Degradation: Low power degradation rate, ensuring prolonged performance. For example, one solar panel has a degradation rate of 1% in the first year, followed by an annual degradation of only 0.40%.
