Shaanxi Bureau of Quality Supervision issued 7 local standards for solar photovoltaic industry

On April 25th, the Shaanxi Provincial Bureau of Quality Supervision officially issued seven local standards, including the “Inspection Rules for Single Crystal Silicon Rods for Solar Cells” and “Inspection Rules for Single Crystal Wafers for Solar Cells.” Two of these standards are directly equivalent to international standards. Standards, some indicators exceed international standards. This marks the solar photovoltaic industry in Shaanxi Province, and it is in the early stages of development to seize the commanding heights of industrial development.

Solar energy is a green and environmentally friendly energy source. It is safe, pollution-free, long-lived, easy to maintain, sustainable, and free of geographical restrictions. It is considered to be the most important new energy source in the 21st century. As of the end of 2010, China's domestic photovoltaic cell production reached 8GW, accounting for 50% of the world's total output, and remained the first for four consecutive years. As one of the earliest provinces in the country to carry out photovoltaic technology research, equipment manufacturing, and engineering applications, Shaanxi has more than 80 companies engaged in solar photovoltaic industry, involving industrial silicon smelting, solar cell manufacturing, and solar photovoltaic related equipment manufacturing. More complete solar photovoltaic industry chain layout.

To improve the core competitiveness of the industry and promote the effective docking of upstream and downstream companies in the solar photovoltaic industry chain in the province, based on the adoption of international standards and domestic advanced standards, establish solar energy in terms of product specifications, technical specifications, quality requirements, inspection and inspection, etc. The unified standard system of photovoltaic industry is particularly critical. To this end, the Shaanxi Provincial Bureau of Quality Supervision jointly organized the Shanxi Provincial Electronic Information Group Co., Ltd. and the Zhongdian Investment Xi’an Solar Power Co., Ltd. jointly with the Shaanxi Provincial Ministry of Industry and Information Technology to jointly formulate the “Inspection Rules for Monocrystalline Silicon Rods for Solar Cells” and “Use of Solar Cells. Single Crystal Wafer Inspection Rules, "Crystalline Solar Cell Inspection Rules", "Crystalline Crystalline Silicon Photovoltaic Module Raw Material Inspection Rules", "Crystalline Crystalline Silicon Photovoltaic Module Inspection Rules", and "Photovoltaic Devices Part 10: "Linear measurement method" and "Automatic disconnection between grid-connected generator sets and public low-voltage power grid" 7 technical standards.

These seven standards cover all aspects of the solar photovoltaic industry and have achieved "three unifications", namely the unification of the terminology of solar-related products, the unification of the quality requirements of fair trade in related products, and the unification of test items and methods for technical indicators. . Among the 7 standards, the two standards “Photovoltaic Devices Part 10: Linear Measurement Methods” are directly equivalent to adopting international standards, and some of the indicators not only exceed the requirements of international standards, but also are at the leading domestic level, such as “single crystal for solar cells”. The silicon wafer thickness specified in the standard for silicon wafer inspection is from 140 micrometers to 200 micrometers, which is much higher than the 400 micrometers requirements set by international standards.

It is reported that the 7 standards will be formally implemented on May 1.
