On June 24, seven companies including JinkoSolar, Jingao, Artus, Luan Solar, and Longji Co., Ltd. jointly launched the “Joint Initiative on Establishing Standard Dimensions for the PV Industry”.

Joint initiative on establishing standard dimensions in the photovoltaic industry

Fellow photovoltaic colleagues:

In recent years, with the continuous development of industrial technology and scale, photovoltaic has gradually become one of the most competitive power sources in the world. While the industry is developing rapidly, many companies are actively innovating and exploring multiple ways to improve the performance of photovoltaic products. Among them, high-power components based on large-size silicon wafers are one of the main directions of innovation for upstream and downstream companies in the industry in recent years. However, in this process, the size of the silicon wafers adopted by enterprises is not uniform, resulting in the increase in the manufacturing cost of the photovoltaic industry chain, including silicon wafers, batteries to components, and auxiliary materials such as glass, and the choice of customers’ products, the installation of photovoltaic systems. Downstream coordination has caused great problems.

To change this situation and promote efficient and standardized development of the industry, we jointly advocate the establishment of a silicon wafer standard (M10) with a geometric size of 182mm*182mm, and include this size in the standard specification file in the industry standards organization to reduce waste of resources. Promote the healthy development of the photovoltaic industry.

Here, we jointly propose and call on our colleagues to join us in taking the size of the silicon wafer in this initiative as the standard size for the development of next-generation silicon wafers, batteries, and component products to promote the establishment of a unified standard-based supply chain system for the entire industry , To achieve the standardization of equipment manufacturing system and customer application system, and promote the healthy development of the entire industry.
