China Releases Two Mandatory National Standards for PV Modules, Taking Effect in June 2027

According to MIIT Official WeChat account, two new mandatory national standards targeting photovoltaic module safety and nameplate labelling were officially released on May 25, 2026. Formulated under the organisation of the Ministry of Industry and Information Technology, the two standards will be fully implemented on June 1, 2027, delivering standardised industrial rules to regulate market competition and drive high-quality upgrading of China’s photovoltaic sector.

The Mandatory National Standard for PV Module Safety Requirements establishes comprehensive technical specifications covering electrical safety, mechanical stability, fire prevention and hazardous substance restrictions, with complete testing methodologies attached for industrial implementation. It sets clear rules for electrical protection and insulation performance, and defines quality thresholds for raw materials and core components used in PV module production. In terms of fire safety, the standard regulates hot spot durability, fire resistance grading and material flame retardancy, effectively mitigating fire risks caused by component ageing, heat accumulation and flame spread during operational lifecycles.

The Mandatory National Standard for PV Module Nameplate Marking Requirements standardises overall labelling specifications, mandatory display contents and electrical parameter labelling rules. It clarifies tolerance ranges and verification methods for nominal power, short-circuit current and open-circuit voltage. All marked parameters must maintain deviations within fixed tolerance ranges or ±2 percent of tested actual values. Rigorous requirements are also imposed on laboratory measurement uncertainty and data traceability, eliminating irregular parameter marking and false performance publicity across the industry.

The rollout of the two mandatory standards drives domestic PV manufacturers to upgrade product design, production techniques and manufacturing equipment to meet unified compliance criteria. Standardised production will lift overall product safety and quality benchmarks, rectify irregular market competition behaviours and consolidate the orderly development of the domestic photovoltaic industry.

Relevant governmental departments will continue to strengthen industrial supervision and standard popularisation after the official implementation. Systematic guidance will be provided for enterprises to accelerate compliant production iteration and optimise product quality stability.

The updated standards align closely with international advanced industrial norms. They reinforce the global brand influence of Chinese photovoltaic products and support the export of China’s independent industrial standards. Continuous standard optimisation will further strengthen the core competitiveness of China’s photovoltaic industry in the global new energy market and facilitate steady industrial iteration and upgrading.
