Joint appeal: Photovoltaic companies once again advocate the standardization of 72-inch rectangular wafer size

According to the news from this website on August 18, according to the WeChat public account of Longi Green Energy, representatives of six photovoltaic companies including Canadian Solar, Risen Energy, Longi, Tongwei, Yiyi, and Chint New Energy have conducted comprehensive and thorough communication and evaluation.A consensus was reached on the standardized size of the rectangular silicon wafer used in the 72 version 191. mm*191.6 mm

The diameter of the rectangular silicon wafer is 262.5 mm

Six photovoltaic companies jointly advocated and promoted the above standardized rectangular silicon wafer size plan It has been accepted by more companies in the industry, and is said to be "in order to further solve the difficulties in supplying silicon wafers in the industry chain and increasing material costs caused by differences in the size of rectangular silicon wafers." Six photovoltaic companies jointly advocated and promoted the above-mentioned standardized rectangular silicon wafer size solution so that more companies can accept it, saying that it was to further solve the difficulties in silicon wafer supply and material costs in the industry chain caused by differences in rectangular silicon wafer sizes.

This site found that this is not the first time that photovoltaic companies have jointly requested to unify the size of silicon wafers. As early as last month, representatives of nine component companies, including Canadian Solar, Risen Energy, JA Solar, Jinko, LONGi, Trina, Tongwei, Yiyi, and Chint, announced that they had reached a standard size standard for the new generation of rectangular silicon wafers. The consensus is as follows: 238mm*1134mm

Rewritten into Chinese: Component with size 2382mm*1134mm

Long side longitudinal hole of component The pitch is: 400mm/790mm/1400mm

At the same time, 9 companies advocate that the industry’s current and future 182 series modules and 210 series module size designs should follow the Chinese photovoltaic industry The regulations in the association standard "T/CPIA0003-2022 Technical Requirements for Outline Dimensions and Installation Holes of Ground Crystalline Silicon Photovoltaic Modules" and the existing dimensions in the industry
