Sun-Earth’s Super Multi Bus-bar (SMBB) technology marks a breakthrough in solar panel manufacturing. Employing an AI-controlled sub-millimeter precision welding system, we precisely join 16 Main Bus-Bars, each less than 0.3mm thick, to nearly 400 minor Bus-bars per cell. Each DXM8-72HBG module boasts over 10,000 meticulously welded points, completed in under a minute on Sun Earth Solar production line.

The SMBB drives higher efficiency and reliability in solar modules. By incorporating finer and more numerous Bus-Bars, SMBB reduces shading and shortens current transmission distances, effectively decreasing series resistance and enhancing current collection. This innovation not only increases solar cell tolerance to micro-cracks and fractures, but also boosts panel output power by up to 2%.

Sun Earth's Thermal Laser NDC Machine introduces a non-destructive laser cutting technology that divides the wafer into two pieces to enhance module efficiency. This method preserves the single-crystal structure of the silicon wafer, minimizing the risk of micro-cracks and maintaining the structural integrity essential for high-performing solar panels. This technology not only improves the yield but also ensures the longevity and reliability of the photovoltaic products.

The Solar Cell Sorting Machine utilizes an advanced machine learning algorithm coupled with both Electro-luminescent and visible light range analysis. This dual approach allows for comprehensive defect detection at micro-level precision. Each wafer undergoes thorough testing before moving to the final assembly line, ensuring that only the highest quality products proceed. The use of sophisticated scanning technology provides an unmatched level of quality control.
