Three mandatory national standards for photovoltaic energy consumption and energy efficiency were officially released!

It is reported that the three compulsory national standards for the photovoltaic industry, namely, crystalline silicon photovoltaic modules and implemented on January 1, 2027. The

three standards set the energy consumption and energy efficiency indicators of related products at different levels, and strictly control the high energy consumption and inefficient production capacity of each link. The first two standards for photovoltaic wafers and modules were issued for the first time, and there was no mandatory entry threshold in this field before. The Energy Consumption Limit for Polycrystalline Silicon and Germanium Unit Products is a newly revised version. Compared with the draft for comments and the draft for approval, some indicators of the official version of the standard are more stringent. According to

the Energy Consumption Limit of Polycrystalline Silicon and Germanium Unit Products, the energy consumption standards of trichlorosilane method and silane fluidized bed method are 6.3kgce/kg and 4.3kgce/kg respectively. The comprehensive energy consumption of the existing silicon material production capacity mostly falls between 6.3 and 6.

The three-level energy consumption standards for polycrystalline silicon are as follows:

the Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Crystalline Silicon Photovoltaic Modules and Inverters, the minimum requirements for photoelectric conversion efficiency are set for each level of energy consumption products of the mainstream module technology routes TOPCon, HJT and BC in the market, which are 23.2% and 23.2% respectively. 23.

The Energy Consumption Quota for Unit Products of Silicon Single Crystal stipulates that the energy consumption standards for rod drawing and slicing are 2.
