Three Mandatory Photovoltaic Energy Standards Effective January 2027
China has issued three mandatory national standards governing energy consumption and efficiency in the photovoltaic sector, with formal implementation beginning in January 2027. The standards aim to keep low-efficiency products out of the market at the source and drive technological iteration and green upgrading of the solar industry. Two standards set energy consumption limits for monocrystalline silicon and for polycrystalline silicon and germanium production, while the third establishes energy efficiency grades for crystalline silicon photovoltaic modules and inverters across ground-mounted power stations and commercial, industrial and residential installations.
Three mandatory national standards on energy consumption and energy efficiency in the photovoltaic sector will be formally implemented from January 2027. The standards will strictly control low-efficiency products from entering the market at the source, driving technological iteration and green upgrading of the photovoltaic industry.
On energy consumption control for manufacturers, two mandatory national standards, the Energy Consumption Limits per Unit Product for Monocrystalline Silicon and the Energy Consumption Limits per Unit Product for Polycrystalline Silicon and Germanium, focus on the core raw materials of photovoltaic modules and unify the scope of energy consumption statistics and calculation methods.
On product energy efficiency improvement, the mandatory national standard on Energy Efficiency Limit Values and Efficiency Grades for Crystalline Silicon Photovoltaic Modules and Inverters sets efficiency grades for photovoltaic modules and inverters used in scenarios including ground-mounted power stations, commercial and industrial installations, and residential photovoltaic systems.
