Technological Innovation and At the annual conference of China's PV industry in 2023, Trina Solar's "210R Rectangular Wafer Design and Unified Module
Size for Medium-sized Modules" was selected as one of the "PV Industry Innovation Achievement Recommendation
Informatization Development Catalog of 2023" given its technological originality and value in the industry. Introduced by Trina Solar in April 2022,
the 210R matrix wafer broke the industry's mindset of square silicon wafers, and rectangular technology has gradually
become an important path for cost reduction and efficiency increase in the PV industry.
With the application of rectangular silicon wafers, 210R medium-format module has excellent size and electrical
compatibility, and the container space utilization rate has reached 98.5%. It is up to the top grid design, which is currently

We have set key performance indicators (KPIs) concerning supplier quality management. Such KPIs include the defective rate (DR)
for each batch, the parts per million (PPM) of production lines, and the percentage of purchases from suppliers in the Approved

to improve their quality management systems to be more competitive in the market.
Since September 2023, the Company has optimized the management and control mode for incoming materials inspection and
launched a digital Incoming Quality Assurance (IQA) system to standardize the management of the inspection standards and
contents for incoming materials from suppliers. Since the system can directly output inspection results, the efficiency and
accuracy of incoming material inspection have been greatly improved. Currently, the IQA system has been rolled out for use at all
