Two mandatory national standards for photovoltaic modules have been issued, specifying safety requirements to eliminate power "overrating".

The State Administration for Market Regulation and the National Standardization Management Committee have approved and issued mandatory national standards "Safety Requirements for Photovoltaic Modules" and "Requirements for Nameplate Identification of Photovoltaic Modules", which will take effect on June 1, 2027. It is understood that these two standards were proposed and coordinated by the Ministry of Industry and Information Technology. The "Safety Requirements for Photovoltaic Modules" specify requirements for electrical safety, mechanical safety, fire safety, restrictions on harmful substances, and describe corresponding test methods. In terms of fire safety, the standard not only specifies the fire resistance level and combustion performance of photovoltaic modules, but also sets rigid indicators for the flame retardancy of component materials, aiming to comprehensively reduce the risk of photovoltaic module fires. In the "Requirements for Nameplate Identification of Photovoltaic Modules", the maximum allowable tolerance and verification value of the electrical performance parameters on the module nameplate are specified, measurement methods are clarified, requirements for traceability of measurement values are set, and measurement results can be traced back to prevent the phenomenon of power "overrating".
