Edobo solar
100mw 300mw production line of solar panel for factory
Product Description
Incoming Material Inspection: Raw materials (wafers, glass, encapsulant, backsheet, aluminum frames, junction boxes, etc.) are inspected for quality and conformity to specifications.
Cell Processing (if applicable): If the factory starts with bare wafers (rather than pre-processed cells), this stage involves texturing, diffusion, anti-reflective coating, and metallization to create the solar cells. This is a highly specialized area, often done by separate companies. Most panel assembly lines start with pre-made cells. Cell Testing and Sorting: Individual solar cells are tested for electrical performance (voltage, current, efficiency) and sorted into bins based on their characteristics. Tabbing and Stringing: Cells are interconnected into strings using thin, conductive ribbons (tabbing ribbon). String Inspection: Strings are inspected for defects (misaligned cells, broken ribbons, soldering issues). This can be manual or automated (using a 90-degree flip machine, as discussed earlier). Layup: Strings are arranged on a sheet of glass (with encapsulant) in the desired configuration to form the panel matrix. Busbar Welding: Busbars (wider conductive ribbons) are welded to the ends of the strings to connect them electrically and create the panel's main current collectors. Pre-Lamination Inspection: The assembled matrix is inspected again before lamination. Lamination: The entire assembly (glass, encapsulant, cell matrix, backsheet) is heated and pressed under vacuum to bond the layers together and create a sealed, weatherproof module. Edge Trimming: Excess encapsulant and backsheet material are trimmed from the edges of the laminated module. Framing: An aluminum frame is attached to the perimeter of the laminated module for structural support and ease of mounting. Junction Box Attachment: The junction box (containing bypass diodes and output connectors) is attached to the back of the panel. Final Testing: The finished panel undergoes a series of tests: Sun Simulation: Measures the panel's power output under standard test conditions (STC). Electroluminescence (EL) Testing: Detects microcracks, cell defects, and other hidden flaws. Wet Leakage Current Test: Measures the resistance in wet weather. Insulation Test: Measures insulation quality. Grounding Test: Measures grounding quality.
Sorting and Packaging: Panels are sorted based on their power output and packaged for shipment.
