On November 4, the Ministry of Industry and Information Technology (MIIT) released its updated list of photovoltaic (PV) manufacturing enterprises meeting the "PV Manufacturing Industry Standard Conditions." A total of 129 companies qualified, with Jiangsu province leading the nation by contributing 35 firms—the highest among all regions. These enterprises primarily operate in downstream segments like cells, modules, and auxiliary materials, underscoring Jiangsu's pivotal role in the PV industry.
The selection process involved self-assessment reports, local reviews, expert evaluations, on-site inspections, and public disclosure, as stipulated by the "PV Manufacturing Industry Standard Conditions (2024 Edition)" and its accompanying management measures.
Changzhou emerged as Jiangsu's top city with eight compliant PV firms, followed by Suzhou (7) and Yangzhou (4). This distribution aligns with Jiangsu's cluster-based industrial development strategy. Changzhou and Suzhou, as core hubs in the Yangtze River Delta PV sector, host production bases for industry leaders like Trina Solar and Canadian Solar, forming a complete supply chain from wafers to modules. Meanwhile, Yangzhou, Zhenjiang, and Wuxi leverage their supporting industries to bolster key supply chain segments.
Jiangsu's 35 compliant firms span the entire PV manufacturing chain—from polysilicon (e.g., Jiangsu Zhongneng Polysilicon) to ingots/wafers (e.g., Jiangsu GCL Silicon Materials) and cell/module production (e.g., Trina Solar, Suntech Solar)—showcasing the province's integrated, cluster-driven industrial advantage.
Polysilicon producers accounted for 10 entries, including three subsidiaries of
In September, MIIT issued a preliminary draft of the compliance list for public feedback. Industry sources noted the 2024 review emphasized operational performance, R&D investment, technical upgrades, energy efficiency, and intellectual property management, with non-compliant firms removed.
The 2024 standards introduced stricter requirements for technology, capacity utilization, and energy consumption. For instance, new monocrystalline PV cell and module projects must now achieve minimum average efficiencies of 23.7% (P-type) and 26% (N-type), up from 23% and 25%, respectively—raising the bar for new capacity and curbing redundant investments.
A key revision mandates a minimum 30% capital ratio for all new and expanded PV manufacturing projects (up from 20% for non-polysilicon projects), steering companies toward innovation and quality over pure capacity expansion.
