On September 24, Solargiga held a ceremony at its Chuanghui factory in Jinzhou to mark the completion of a high-efficiency module production line upgrade and the rollout of the line’s first module. The retrofit was completed in 68 days — from design confirmation to trial production — entirely within the existing facility, and the upgraded line can reach an annual production value of up to RMB 1 billion.
The upgraded line was built to support Chint Anneng’s delivery needs in northern China. The ceremony was attended by Tong Shengqiang, Deputy Secretary-General of the Jinzhou Municipal People’s Government; Tan Xin, Chairman of the Board and CEO of Solargiga; and Zhao Mingtao, General Manager of the Integrated Supply Chain Center at Chint Anneng. All three signed the first module and toured the upgraded line.

Strategic Location for Northern China Markets
According to Q1 2026 provincial data released by the National Energy Administration, cumulative grid-connected solar capacity in Beijing-Tianjin-Hebei and the three Northeast provinces stood at 131.1 GW at the end of March, about 47% of which was distributed. Located between the three Northeast provinces and Beijing-Tianjin-Hebei, Jinzhou is well positioned to serve both regional markets.
Chint Anneng, the CHINT Group’s green energy services arm, operates across 29 provinces with over 2 million residential stations deployed. The partnership between Solargiga and Chint Anneng began in 2022; Solargiga was named a CHINT Group Advanced Supplier and received the Quality Management Excellence Award in 2024, followed by a strategic cooperation agreement in 2026.
Zhao Mingtao noted that distributed solar is shifting from scale expansion to quality-driven development, and that the developer-manufacturer relationship is evolving from transactional procurement to deep collaboration. “The upgraded Jinzhou facility gives us greater confidence in advancing our northern projects,” he said.
68-Day Retrofit: Cross-Functional Execution
Production, process engineering, equipment, facility, electrical, and quality teams worked in parallel throughout the retrofit, with daily progress tracking and weekly updates to Chint Anneng.
“Time was tight, but standards never dropped — every critical stage was inspected item by item,” said Tan Xin.
“68 days answers whether your partners can keep up when the market needs you,” said Zhao Mingtao.
Upgrade Highlights: Efficiency, Quality, and Traceability
Operational since May 2018, the Chuanghui factory has previously advanced busbar technology from 5BB to 10BB (2020–2022) and, in 2024, introduced 210R rectangular cells and completed its transition to N-type technology. This latest upgrade focuses on efficiency, quality, and traceability:
• Dual-head material changing at loading stations to enable non-stop material replenishment
• Constant-temperature flexible soldering to reduce the risk of cell breakage
• Dual-layer lamination with three-machine linkage for improved space utilization
• Three-stage quality control — pre-lamination, post-lamination, and final — combining AI visual recognition, manual review, EL testing, and power measurement
• MES barcode traceability linking every module from raw material to finished product throughout its warranty period
The line covers the full N-type TOPCon portfolio and is designed to accommodate future transitions to BC and quarter-cut cell technologies.
Looking Ahead
The line is now in capacity ramp-up and quality validation.Tan Xin emphasized: “Completing the line is only the beginning — consistency in mass production, on-time delivery, and field performance must all stand up to scrutiny.” Solargiga will continue ramping in line with jointly agreed customer milestones, building Jinzhou into a stable long-term delivery hub for northern China.
