October 14 marks World Standards Day, and we pay tribute to standardization workers worldwide. From traditional agriculture to smart factories, and from food safety to energy transition, standards serve as the cornerstone of quality and even a bridge connecting the present to the future.

Tongwei, deeply rooted in agriculture and new energy, has embedded our commitment to standards into our "DNA". From safeguarding food safety to leading the green energy revolution, and from establishing the first "Lighthouse Factory" in the global PV cell industry to participating in the development of global industry standards, we are setting benchmarks for the industry and creating value for the world through multi-dimensional "Tongwei Standards".

Agricultural Sector: Safeguarding "Safety on the Tip of the Tongue" with Rigorous Standards

In the agricultural and animal husbandry sector where Tongwei originated, we have implemented the high standards that are "replicable, traceable, and sustainable" throughout the entire process to uphold the solemn commitment to life health and food safety. We have established a full-chain traceability system covering seedling, feed, breeding, and food processing. Each seedling is based on the quality of an "agricultural and animal husbandry chip"; each grain of feed uses carefully selected raw materials, with strict control over nutritional ratio and production processes to ensure safety and efficiency; and the industrialized recirculating aquaculture model for prawns takes ecology and health as standards to safeguard the quality of aquatic products from the source.

While continuously consolidating our own standards, Tongwei also promotes the mature and reliable "Tongwei Technology" to thousands of farmers. Relying on the TSC service system, we help farmers achieve scientific breeding, cost reduction, and efficiency improvement. We are not only committed to advancing agricultural modernization, but also bolster national food security with high standards.

New Energy Sector: Pioneering the Green Intelligent Manufacturing Revolution with Ultimate Standards

As a leading enterprise in the global PV industry, Tongwei integrates standardization into the entire new energy industry chain. We not only solidify fundamental quality, but also raise the industry benchmark with "intelligent manufacturing standards".

Full-Chain Fundamental Standards

The Ultimate Pursuit from "Purity" to "Efficiency"

High-Purity Crystalline Silicon: Achieving the "Gold Standard for Purity"

Tongwei's high-purity crystalline silicon products reach a purity of 99.999999999% (11 nines), far exceeding the industry average. This "ultimate standard" not only ensures the high efficiency and reliability of basic materials, but also becomes a benchmark for global polysilicon production through the independently developed "Yongxiang Method" process standard. Our electronic-grade polysilicon products lead the industry in quality and comprehensive technical indicators, with mass export to overseas markets, realizing the "intelligent manufacturing of high-purity crystalline silicon in China".

High-Efficiency Solar Cells: Breaking Through the "Efficiency Ceiling"

Tongwei's high-efficiency cell technologies such as TNC and THC continually break world records for conversion efficiency. Meanwhile, we have established a rigorous standard system covering processes, manufacturing procedures and quality control to ensuring every solar cell leaving the factory boasts industry-leading power generation performance and long-term reliability.

High-Efficiency Modules: Establishing "Industrial Synergy Standards"

Through full industrial chain integration, Tongwei has achieved seamless "system standards" from silicon materials to modules. This not only optimizes the production process, but also guarantees the consistency of product quality, ultimately providing global customers with PV products featuring lower levelized cost of electricity.

Intelligent Manufacturing Benchmark

The World's First "Lighthouse Factory" in the Global PV Cell Industry

From the world's first Industry 4.0 high-efficiency PV cell production line to the first global PV 5G application base, Tongwei Solar (Meishan) Co., Ltd. has been awarded the title of the world’s first "Lighthouse Factory" in the global PV cell industry, thanks to over 50 application scenarios of the Fourth Industrial Revolution (4IR), which has redefined the "standard metrics" for cell manufacturing where "standards" are translated into quantifiable digital miracles. By advancing transformation with "self-imposed standards higher than the industry's standards" Tongwei has made the Meishan Factory a "standard textbook" for global PV intelligent manufacturing.

Dual Green Development: Fulfilling the Sustainable Mission with "Strategic Standards"

Tongwei's unique dual green development model combining "agriculture + new energy" is an innovative "corporate strategic standard". Through the innovative practice of "integration of fishery and PV", Tongwei has achieved intensive land use that enables "power generation above and fish farming below". The success of this model stems from the deep integration of the two industrial standards, which offers a "Chinese Solution" and "Tongwei Model" for global sustainable development, truly transforming "green standards" into ecological value.

Industry Co-construction: From "Corporate Standards" to "Global Consensus"

Tongwei's standardization practices is extending from internal corporate operations to industry-wide co-construction. At the recent Promotion Conference for Low-Carbon Assessment Requirements for Exported PV Modules, Tongwei was awarded a certificate as a drafting unit of the standard. The standard will be implemented in 2026 and will become an important foreign economic and trade guideline for regulating PV exports. It also vividly reflects Tongwei's development logic of "from factory practice to standard output".

Additionally, Tongwei actively participates in formulating multiple industry standards, including ESG Information Disclosure Standards for Energy Enterprises, Green Product Evaluation for PV Modules and Inverters, General Specification for Carbon Neutrality of Photovoltaic Power Station Construction and General Specification for Carbon Neutrality of Photovoltaic Power Station Operation. We are committed to promoting the high-quality development of the PV industry through full-chain standardization.

Illuminating a Green Future with Standards as a Beacon

The theme of World Standards Day evolves, but Tongwei's original aspiration to practice standards remains unchanged. We are well aware that "first-class enterprises set standards". Our goal extends beyond "meeting standards"; it lies in "defining and leading standards".

In the future, Tongwei will continue to uphold our corporate vision of "For a Better Life". We will consolidate the foundation of agriculture and contribute to green energy with higher, stricter, and more forward-looking "Tongwei Standards". This will not only light the path for the upgrading of "Intelligent Manufacturing in China" but also convey to the world the Chinese wisdom of "driving the energy revolution through standards".
