Product Manufacturing Process

The ASTRO N7s bifacial series solar panels are crafted through a highly efficient manufacturing process that involves several critical stages. Firstly, the n-type mono-crystalline cells are produced using TOPCon (Tunnel Oxide Passivated Contact) technology, which enhances the cells' efficiency and reliability. The cells are then interconnected using ZBB-TF (Zero-busbar Tiling Film) technology, minimizing power loss and maximizing the module's power output. The panels are encapsulated with high-transparency glass on both the front and back to allow bifacial energy generation. Rigorous quality control measures are implemented throughout the process, ensuring each panel meets high standards of performance and durability. Authoritative studies and industry data suggest that n-type TOPCon technology significantly improves the module's efficiency and lifespan, reaffirming PVSTAR's commitment to quality and innovation.

Product Application Scenarios

The ASTRO N7s bifacial series can be seamlessly integrated into various rooftop scenarios, including residential, commercial, and balcony installations. For residential applications, these panels offer homeowners the ability to generate their own electricity, reduce energy bills, and increase property value. Commercial installations benefit from the panels' high efficiency, providing businesses with a reliable and renewable energy source, enhancing their sustainability credentials. Balcony installations are an innovative solution for urban living, allowing apartment dwellers to harness solar energy within limited space. Research and market data indicate a growing trend towards diversified photovoltaic applications, driven by the need for sustainable energy solutions and the flexibility offered by modern solar technologies.
