Product Manufacturing Process

The manufacturing process of the ASTRO N7s Bifacial Series solar panels involves several critical steps to ensure high efficiency and long-term performance. It starts with the selection of high-purity silicon wafers, followed by the application of n-type TOPCon 4.0 technology to enhance electrical characteristics. These wafers are meticulously assembled into cells, which are then interconnected using Zero-busbar integrated interconnection (ZBB-TF) technology. This method eliminates the busbar, reducing resistance losses and improving overall efficiency. The cells are encapsulated between layers of tempered glass and an anodized aluminum frame to provide robustness and durability. Each module undergoes rigorous testing under simulated real-world conditions to ensure compliance with international standards and performance benchmarks. As a result, these modules achieve a maximum efficiency of 23.0% and are designed to withstand harsh environmental conditions, making them an excellent choice for both residential and commercial applications.
