Large-size silicon wafer has obvious advantages, which can improve the efficiency and reduce the cost for downstream batteries, components and power stations, and lead the new demand of the future industry. At the manufacturing end, large-size silicon wafers can increase the output of silicon wafers, batteries and components, thus reducing the production cost per watt; In terms of products, large size can effectively improve battery power and component efficiency by optimizing component design; In terms of system, with the improvement of power and efficiency of single module, large size can reduce the cost of bracket, junction box, cable and land, and dilute the cost of single tile.

With the rapid introduction of large-size silicon wafers/batteries/components, the market demand for new equipment is basically implemented according to the backward compatibility standard of 2 10, and a large number of incremental equipment will gradually replace existing equipment. Because it is difficult to directly upgrade the equipment before 2020 to 2 10 large-size equipment through transformation (most equipment before 2020 can be upgraded to 182 large-size equipment through transformation, but it is difficult to upgrade to 2 10 large-size equipment), if 2 10 large-size equipment becomes the market in the next 2-3 years,
