Reaching a Consensus on the Standardization of the 72-type Rectangular Silicon Wafer Size

After the photovoltaic industry unifies the size of the medium-sized module (2382x1134mm) of the new generation of rectangular silicon wafers, in order to further solve the difficulties in the supply of silicon wafers in the industrial chain and the increase in material costs caused by the size difference of rectangular silicon wafers, the promotion of rectangular silicon wafers Standardization of dimensions is critical.

Representatives of six photovoltaic companies, Canadian Solar, Risen Energy, LONGi, Tongwei, Yidao, and Chint New Energy, reached the following consensus on the standardized size of rectangular silicon wafers of 191.Xmm used in the 72 version after comprehensive communication and evaluation:

Margin of rectangular silicon wafer: 182.2mm*191.6mm

Rectangular wafer diameter: 262.5mm

The six photovoltaic companies jointly advocated and promoted the above-mentioned standardized rectangular silicon wafer size solution, which has been accepted by more companies in the industry.
