Jinko Solar(SH:688223)2025-05-08 02:20Company and Industry Summary Company: JinkoSolar (晶科能源) Key Points 1. Technology Upgrade Significance: The power difference between leading and lagging TOPCon products has widened by 20-30W, which may lead to the elimination of lagging TOPCon production capacity. This technology upgrade is seen as a proactive measure to seek new opportunities [1][2][3] 2. Production Capacity Upgrade: By the end of the year, 40%-50% of JinkoSolar's TOPCon production capacity is expected to be upgraded, achieving power levels of 650-670W. The facilities in Shangrao and Shanxi, with capacities of several GW and 8GW respectively, have already completed upgrades [2][3] 3. Current Power Levels: The upgraded modules currently have a power output of 640-645W, with a target to reach 645-650W by June [2][3] 4. Efficiency Improvement Methods: This year, the main methods for efficiency improvement include edge passivation, 0BB, and MAX (back laser), which are expected to enhance power by 10-15W. Future methods planned for the next couple of years include invisible busbars, low-temperature battery technology, and stacking techniques [3] 5. Introduction of Low-Cost Metals: The evaluation of the R&D line has been completed, and the mass production line is expected to officially operate by mid-May. A comprehensive mass production assessment is scheduled for June, with plans to complete at least 1-2 workshop renovations and actual production within the year. It is anticipated that 20%-40% of production capacity will be introduced into actual mass production this year, with full product integration expected next year [3]
