Product Manufacturing Process

The manufacturing process of photovoltaic modules like the ASTRO N7s series involves several key steps. Initially, high-purity silicon is processed into ingots which are then sliced into thin wafers. These wafers undergo a series of cleaning and texturizing steps to enhance light absorption. The n-type mono-crystalline cells are then constructed using the TOPCon (Tunnel Oxide Passivated Contact) 4.0 technology, which increases efficiency by creating a passivated contact layer that reduces recombination losses. The cells are interconnected using zero-busbar (ZBB-TF) integrated interconnections, which minimize shading and electrical losses. The assembled cells are then encapsulated between layers of EVA (ethylene-vinyl acetate) and protective glass, framed with black anodized aluminum for durability and aesthetics. The final modules undergo rigorous testing to ensure they meet stringent quality and performance standards. This meticulous manufacturing process, backed by research and development, ensures the long-term reliability and efficiency of the ASTRO N7s solar panels.
