Deep-rooted in Aerospace Testing, Jointly Building Standard System: Aijiang Technology Joins CSTM Space Photovoltaic Working Group

Recently, the 3rd "Beneath Freezing Point, Above Quality" High-Latitude Extreme-Cold Test Environmental Technology Innovation Forum convened in Mohe, Heilongjiang. At the forum, the CSTM/FC03/TC22 Space Photovoltaic Working Group under the Solar Photovoltaic System Application Standardization Technical Committee was officially established. Yuan Wuhui, General Manager of Aijiang Technology, was appointed as a member of the working group.

The Space Photovoltaic Working Group aims to fill gaps in China’s space photovoltaic standards. Its core work includes constructing standard systems, developing and revising standards, conducting technical research, test verification and achievement promotion. It facilitates standardized, high-quality and systematic R&D and engineering application of space photovoltaic technologies. As an appointed member entity, Aijiang Technology will draw on its technical accumulation and engineering practices in high-precision aerospace testing. It will actively engage in standardization work of the working group and contribute professional insights from the testing sector to the development of China’s space photovoltaic standard system.

As a national-level high-tech enterprise based in Wuhan, Aijiang Technology has specialized in aerospace-grade precision testing for nearly a decade. It holds over 100 independent core patents, with business covering photovoltaic power, space power supply, energy storage and power semiconductors. Its testing equipment serves leading enterprises across China’s commercial aerospace industrial chain, supporting rigorous quality inspection for aerospace batteries and core payload components. Its products have been deployed in photovoltaic laboratories across 30 countries and regions worldwide, realizing industrialization of high-precision aerospace testing technologies.

The self-developed extra-large-format AM0 transient solar simulator by Aijiang Technology is China’s first dedicated testing platform for ultra-large solar cell arrays. It features spectral coverage from 350 - 1800 nm, irradiance non-uniformity below 2%, and irradiance instability below 1%. All three key parameters meet international Class-A aerospace specifications. This equipment has supported key national projects such as space station solar arrays and deep-space exploration satellites. Products tested by Aijiang Technology have been operating stably in orbit onboard multiple satellites.

Beyond superior hardware performance, Aijiang Technology has integrated AI capabilities into its testing framework. Its testing devices can be equipped with the Xinghan AI 2.0 Intelligent Inspection System, delivering a defect recognition accuracy of 98.7% and over 12-fold improvement in testing efficiency for single modules, with an overall domestic localization rate of 92%. Aijiang Technology’s aerospace-grade testing solutions cover the full chain: individual aerospace battery cells, energy-storage battery modules, power controllers, and complete satellite power subsystems.

Technology is grounded in testing, and industry thrives on standards. Moving forward, Aijiang Technology will leverage its industrial practical experience to deeply participate in space photovoltaic standardization. It will keep optimizing domestic aerospace testing equipment, drive domestic substitution for the space photovoltaic industry via testing innovation, and underpin the high-quality growth of China’s commercial aerospace sector.
