Product Manufacturing Process

Manufacturing solar photovoltaic modules involves several critical steps to ensure quality and efficiency. The process begins with the production of high-purity silicon wafers, which are sliced from ingots. These wafers undergo several treatments, including doping to create p-n junctions, which are critical for generating electric current. The wafers are then assembled into cells, tested for efficiency, and arranged into a grid. The grid of cells is encapsulated between protective layers of glass and a backsheet, forming the module. The module is framed for structural stability and equipped with connections for electrical interfacing. Quality control is crucial at every step, including pre-assembly testing of individual cells, post-assembly testing of the module, and durability testing to ensure long-term performance. This thorough process guarantees high-quality, efficient solar panels suitable for various rooftop applications.
