Solar panel manufacturing is a complex process that transforms raw materials into finished modules capable of converting sunlight into electricity. This process involves multiple stages, from silicon wafer preparation and cell fabrication to module assembly and final testing. Each stage requires specialized equipment and precise control to ensure high efficiency, reliability, and cost-effectiveness. Achieving high-volume production, such as a 300MW annual capacity, demands a highly automated and optimized production line, integrating cutting-edge technologies and rigorous quality control measures.
Building on this foundation of advanced manufacturing principles, we present our 300MW solar panel production line - a proven solution that we have successfully designed, customized, installed, and commissioned for our clients. This production line is not a theoretical concept; it is a fully operational system currently producing high-quality solar panels. The following sections provide a detailed overview of the key equipment and processes that comprise this production line, highlighting the specific technologies and design choices that enable its exceptional performance and reliability. This information will demonstrate how our 300MW solution can meet the demanding requirements of large-scale solar panel manufacturing.

| Gluing and framing all-in-one machine | This all-in-one machine combines the application of adhesive (gluing) and the attachment of the aluminum frame to the laminated solar module into a single, automated process. It streamlines the workflow and reduces handling. | 1 | |
| Glue applicator | The glue applicator, plays a crucial role in ensuring the structural integrity and weather resistance of the solar panel, particularly in securing the junction box and, in some cases, contributing to frame bonding. Precision dispensing, automation, and compatibility with the specific adhesive are key characteristics. | 1 | |
| Automatic Glue Filling Machine | Automatic glue filling machine designed for pre-filling aluminum frame channels with adhesive plays a specialized role in solar panel production. It improves the quality, consistency, and cleanliness of the frame bonding process by applying the adhesive to the frame sections before they are assembled around the laminated module.
