The official website of the Ministry of Industry and Information Technology (MIIT) recently announced that the department has drafted the "Regulations for the Photovoltaic Manufacturing Industry (Draft for Comments)"—referred to as the "Conditions"—aimed at addressing the disorderly growth of China's solar power sector. The new regulations are designed to bring more structure and sustainability to the industry, which has experienced rapid but sometimes chaotic expansion in recent years.
According to MIIT, the "Conditions" are formulated based on the State Council's "Several Opinions on Promoting the Healthy Development of the Photovoltaic Industry" and other relevant national laws and policies. The goal is to ensure that the PV industry grows in a more controlled and efficient manner, while also promoting technological innovation and environmental responsibility.
Industry experts have noted that the past few years saw an overexpansion of the PV sector, leading to market saturation and financial difficulties for many companies. As a result, the need for regulation has become increasingly urgent. The MIIT emphasized that the "Conditions" will be implemented from the date of publication and may be revised in the future to align with industry developments and macroeconomic control needs.
The regulations cover various aspects of photovoltaic manufacturing, including production layout, project establishment, production scale, technology processes, resource utilization, energy consumption, environmental protection, quality management, and supervision. They apply to both existing and new PV manufacturers, covering the entire supply chain—from silicon ingot production, wafer slicing, and cell manufacturing to module assembly, including thin-film PV producers.
Under the new rules, government departments will use the "Conditions" as a basis for supervising investments, land allocation, and environmental assessments. Companies that do not meet the standards may lose access to export tax rebates and domestic application support programs.
In terms of project setup, the "Conditions" emphasize strict control over new PV projects that only aim to expand capacity. Only those that focus on innovation and cost reduction can proceed, and they must be registered with the relevant industry and investment authorities. Additionally, new or renovated projects must have a minimum capital ratio of 20%.
Regarding production scale, the regulations set specific thresholds: polysilicon projects must produce over 3,000 tons annually, silicon ingots must reach 1,000 tons, silicon rods must be at least 1,000 tons, and wafers must exceed 50 million units per year. For existing facilities, actual output should be at least 50% of the stated capacity.
In terms of technology, the "Conditions" require PV companies to have independent R&D centers or high-tech enterprises at the provincial level. Annual R&D spending must be no less than 3% of total sales or 10 million yuan.
The efficiency requirements for crystalline silicon cells have also been raised. Existing manufacturers must achieve at least 16% efficiency for polycrystalline and 17% for monocrystalline cells, with component efficiencies of 14.5% and 15.5%, respectively. New projects face even higher benchmarks, with polycrystalline and monocrystalline cells needing at least 18% and 20% efficiency, and building components requiring 16.5% and 17.5%.
Energy consumption standards are also tightened. Existing polysilicon projects must consume less than 80 kWh/kg, while new projects must stay under 60 kWh/kg. Overall energy use is capped at 140 kWh/kg for existing projects and 100 kWh/kg for new ones.
Quality management requirements include a minimum 25-year lifespan and a 10-year warranty for PV modules.
Finally, the implementation of the "Conditions" will involve regular inspections and public announcements of compliant companies. Non-compliant firms will be required to undergo upgrades through mergers, acquisitions, or technological improvements. All aspects of PV projects—including investment, land use, environmental impact, energy efficiency, quality, safety, and credit—will be managed according to these new guidelines.
Companies must submit applications to the MIIT through provincial industrial authorities, and the ministry will conduct periodic checks to ensure compliance and maintain transparency.
