The Company has been practicing six key strategies of “innovation, branding, globalization, platformization, intellectualization,and industry-finance synergy” to lead the development of the industry. In 2023, our business was generally on an upward trend,
and we have gained increasing trust from our global customers and all sectors of society. During the Reporting Period, Trinasolar

Environmental and human rights
requirements for suppliers

To ensure that Trinasolar's production and operation activities are not adversely affected by the supply of materials, we haveadopted a series of proactive and effective measures to assess and respond to supply chain risks. By participating in theidentification of risk points and regularly assessing and controlling them, the Company is able to identify potential supply chain
risks in a timely manner and formulate corresponding countermeasure strategies to ensure the stability and reliability of the supply
chain. Through the implementation of the "Supply Chain Purchasing Cost Control" program, we pay close attention to market pricefluctuations and utilize advanced analytical tools and methods to enhance the foresight and accuracy of price forecasts. This not
only helps us to rationally control procurement costs and avoid unnecessary losses due to price fluctuations, but also improves
the delivery rate of products and ensures smooth production activities by strengthening the inventory management of main andauxiliary materials. In addition, in order to cope with the complexity and uncertainty of the international trade environment, theCompany has established the "Supply Chain Purchasing Volume Guarantee" program, and conducted an in-depth assessment of the
impact of international anti-circumvention investigations. By enhancing our overseas localized supply capacity, we have not only
met the changes in market compliance requirements, but also further consolidated Trinasolar's market share in the global market
and strengthened the Company's international competitiveness.

In 2023, Trinasolar strengthened the supply chain digitalization. The structure of the system is based on the ERP system andconsists of sales order management (ERP-SO), supply chain planning management (SCP), Supplier relation management (SRM),
manufacturing execution management (MES) and transportation management (TMS) as the main backbones. The systemenables an online management of major business processes within the supply chain from the order generation to order delivery.
In addition, the system enables the visualization of an order’s life cycle management through integrated data.

Trinasolar Supplier EHS and Social Responsibility Audit Scoring Keys

Supplier Selection Grading
In the supplier selection process, Trinasolar has defined different selection principles and qualification standards for different
procurement types, and issued a Potential Supplier Development Questionnaire to potential suppliers. Based on the content of
the questionnaire returned, we investigate the compliance, environmental and social performance, and relevant qualification
documents of potential suppliers. We review the product quality of suppliers at the entry stage to ensure that the quality of
products provided can meet our standards, and then sign high-level agreements with suppliers.

Environmental protection

In addition, we also require primary and secondary suppliers and partners to sign the Trinasolar Supplier Social Responsibility
Commitment at the entry stage. The commitment specifies that all suppliers and their supply chains must understand andcomply with Trinasolar’s policies on the environmental, occupational health and safety, and energy management, as well as
Trinasolar’s requirements for suppliers’ code of conduct.
After the suppliers are on the list of qualified suppliers, we classify them into four levels according to business impact andmarket complexity: strategic suppliers, preferred suppliers, optional suppliers, and restricted suppliers, and conduct performance
management with different frequencies and concerns.
Occupational health andsafetySupplier Performance Assessment
During the Reporting Period, Trinasolar had established and implemented the Supplier Performance Management Code and
the Guidelines for Supplier Quality Management in Product Business to evaluate suppliers' quality, price, delivery capability, andservice level in an objective and fair manner, and to optimize the supplier management mechanism of survival of the fittest.

safety, and environment according to their categories and with different weights. Furthermore, we complete an assessment
and recognition of suppliers based on the evaluation results, while carrying out targeted communication and counseling, andLabor and human rights

performance has been fully included into the supplier performance evaluation. Trinasolar has developed and implemented theManagement Procedure for Supplier EHS and Social Responsibility, which specifies that procurement staff should record therelevant supplier performance in the Supplier EHS and Social Responsibility Form. The form includes 56 assessment indicators of
suppliers’ performance in five areas, namely environmental protection, occupational health and safety, fire safety and emergency
preparation and response, labor and human rights and business ethics, and sustainable procurement.
