Customized Project | JinenU Solar 134MW 210R-66 Module Project

Customized Project

134MW TOPCon Project

Recently, JinenU Solar has received a customized production order from a customer, which focuses on high-efficiency, large-size N-type PV modules - 210R-66 version. The core demand of this order is to customize two kinds of power modules, 605W and 610W, and the total amount of the order reaches 134MW, with a total of 221,168 pieces.

In order to realize efficient production, JinenU Solar has formulated a multi-dimensional production and delivery plan based on the customer's plate type and delivery date, and fully utilized the synergistic advantages of its two production bases in Tai'an and Taizhou, to ensure that it maintains a high yield and high rate of production in the large-scale production at the same time. Through the scientific and reasonable production plan arrangement, the production lines in the two places work closely together to maximize the utilization of resources, effectively shorten the production cycle, and lay a solid foundation for rapid response to customer needs.

Manufacturing Challenges & Solutions

The overall size of this N-type 210R-66 double-glass module is 2382*1134mm, and the cell size is 182*105mm. It uses 0.24mm specification round wire welding tape with EVA400+EPE420 grams+embossed double-coated glass, and the small 0.8mm pitch of the pieces can effectively reduce the grid line shading of the cells, improve the optics utilization, and increase the power of the module.

Due to the use of 0.24mm welding tape in this version, the bending of the welding tape occurs in the spacing of the battery strings of the string welding machine during the trial production, compared with other versions with longer dimensions, hidden cracks at the location of the center hole lead wire, broken pieces caused by the force of the welding tape vertical lamination, hidden cracks in the eight characters after the layer, etc., the manufacturing department of JinenU conducted comprehensive researches from the angle of material selection, design optimization to the adjustment of the lamination machine in the production process. After repeated tests and optimization, we not only successfully solved the current problems, but also provided valuable experience for the subsequent production, improved the production efficiency and product quality, and ensured the timely delivery of orders.

Customer Feedback

"From raw material inspection to finished product shipment, each process is strictly inspected to ensure that each module meets even our expectation standards. In terms of delivery time, JinenU's responsiveness is impressive, in the face of tight time requirements, they quickly mobilized their resources and ensured the steady progress of production through the highly efficient linkage of the two bases in Tai'an and Taizhou. " JinenU Solar always adheres to the values of integrity, goodness, refinement, and honesty, and produces every module with heart and soul.
