In order to implement the decision-making and deployment of the CPC Central Committee and the State Council on promoting the high-quality development of the photovoltaic industry, the Ministry of Industry and Information Technology organized and formulated two mandatory national standards, namely, the Safety Requirements for Photovoltaic Modules and the Nameplate Identification Requirements for Photovoltaic Modules (hereinafter referred to as the two strong standards). It was officially released on May 25, 2026 and formally implemented on June 1, 2027, which will play an important role in standardizing the competition order of photovoltaic industry and promoting industrial upgrading and development.
The Safety Requirements for Photovoltaic Modules specifies the requirements for electrical safety, mechanical safety, fire safety and limitation of hazardous substances of photovoltaic modules, and describes the corresponding test methods. In terms of electrical safety, the electrical protection requirements and insulation protection requirements of photovoltaic modules are stipulated, and the corresponding requirements for raw materials and components used in the modules are put forward; In terms of fire safety, fire safety-related requirements such as hot spot durability requirements, fire rating and combustion performance of photovoltaic modules are stipulated, and flame retardant requirements of component materials are put forward, aiming at reducing the fire risk of photovoltaic modules from the aspects of hot spot reliability of modules, fire resistance and flame spread resistance of module products themselves, and flame retardant of component materials.
The Identification Requirements for PV Module Nameplates specifies the basic requirements for PV module nameplates, identification contents and marking requirements for electrical performance parameters. The tolerance range and verification method of nominal power, nominal short-circuit current and nominal open-circuit voltage are clarified, and the deviation between the nameplate value and the measured value should not exceed the upper and lower tolerance limits or ± 2%, and the requirements of uncertainty and traceability of laboratory measurement are put forward. After the implementation of the
two strong standards, it will produce the following positive effects:
First, build a solid safety bottom line and consolidate the foundation of energy security. "Safety Requirements for Photovoltaic Modules" systematically improves the core performance of electrical safety, mechanical safety and fire safety of components by establishing life-cycle safety standards, and prevents major safety risks such as fire and electric shock from the source. Power system construction and national energy security provide solid technical support.
The second is to standardize the management of signs and reshape the order of fair competition. "Photovoltaic Module Nameplate Identification Requirements" aims at the persistent problems of power false label and other industries, and forces the unification of the labeling specifications and testing methods of nameplate parameters, so as to ensure that the performance data of each module are authentic and traceable throughout the process, effectively curb false publicity and vicious competition of low quality and low price, and promote the formation of a market ecology of high quality and high price.
The three is to lead the value transformation and drive the upgrading of the industry. The coordinated implementation of the two mandatory national standards will strongly promote a fundamental change in the logic of competition in the industry, from the past "price comparison, scale competition" to "reliable competition, technology competition". By setting up a clear red line of safety and quality, enterprises are forced to focus on technological innovation and quality improvement, and help China's photovoltaic industry realize the strategic transformation from "scale leading" to "value leading". In the process of formulating the
two strong standards, opinions and suggestions from manufacturing enterprises, end users, third-party testing and certification, scientific research institutions and relevant administrative departments were widely heard. The standard drafting group organized several rounds of technical seminars to take into account the concerns of all parties and achieve the greatest degree of coordination and balance. After the official release of the two strong standards, photovoltaic module manufacturers will accelerate the design of new products, process improvement and equipment upgrading according to the requirements of the standards, so as to realize the supply of photovoltaic modules that meet the new standards as soon as possible. The
two strong standards are set up for a 12-month transition period, that is, 12 months after the date of issuance, to reserve sufficient time for testing, certification and inventory consumption for enterprises. In view of the specific requirements of the two mandatory standards, the PV industry has mature manufacturing solutions and corresponding test methods, and the implementation of the standards does not involve large-scale technical transformation and cost input. According to the feedback from PV module manufacturers, distributors and users, the inventory of PV module products is small, and it is expected that the consumption can be gradually completed during the transition period of the standards.
In the next step, the Ministry of Industry and Information Technology, together with relevant departments, will continue to strengthen the management of the photovoltaic industry, standardize the market order, strengthen the publicity of the two strong standards, guide photovoltaic enterprises to produce in accordance with the standards as soon as possible, further improve the level of product quality and safety, and accelerate the transformation, upgrading and development of the photovoltaic industry.
