Promoting Sustainable Manufacturing 

Trina Solar actively promotes sustainable manufacturing practices within the solar industry. The company ensures industrial carbon emission reduction by implementing these eco-friendly strategies and optimizing resource utilization. 


Establishing an EHS Committee 

Trina Solar established its EHS (Environmental, Health, and Safety) committee in 2009 in line with its dedication to decarbonizing the solar industry. This committee drives the company's sustainability initiatives, ensuring compliance with local and national environmental laws and regulations. 

The EHS committee plays a critical role in overseeing Trina Solar's manufacturing processes and facilities to minimize the environmental impact. They conduct regular audits, inspections, and assessments to identify areas for improvement and implement effective measures accordingly.  

Trina Solar stays up-to-date with the latest environmental regulations and best practicesby maintaining close relationships with relevant authorities and industry organizations. The company also regularly updates its organizational structure and conducts employee training to comply with new EHS laws and waste management. 

In addition, Trina Solar actively participates in conferences, workshops, and collaborative initiatives. The programs foster knowledge sharing and promote sustainable manufacturing practices across the solar industry. 

Trina Solar's EHS committee works closely with other departments within the organization. For instance, the EHS collaborationwith the research and development (R&D) team allows the company to integrate sustainable technologies into manufacturing processes. This teamwork promotes proper energy management and reduces environmental impact.

Establishing Green Factories 

Trina Solar recognizes the importance of establishing green factories both locally and abroad. These factories adhere to an internal environment management system that meets theISO 14001 certification

Trina Solar's factories use environmental management manuals that serve as detailed guides for sustainable operations. They include: 

  • The Environmental, Occupational Health and Safety, and Energy Management Manual 

  • The Photovoltaic Project Manual 

The manuals outline best practices for waste management, energy conservation, water usage, and emission control. Implementing these manuals ensures the company’s manufacturing processes align with stringent environmental standards. 

In addition, Trina Solar's commitment to sustainability is reflected in implementing various environmental management systems. They include: 

  • The EHS Monitoring Management Procedure 

  • The EHS Management Review Procedure 

  • The Construction Project EHS Management Procedure 

Implementing these strategies enables our facilities to obtain certifications such as "Net Zero Factory", "Green Factory", and "Green Building". 

One notable example of Trina Solar's dedication to green factories is the new Qinghai factory within a net-zero industrial park. In March 2022, Trina Solar signed a strategic cooperation agreement with the Qinghai Provincial Government to jointly build the Integrated Net Zero Industrial Park. This initiative demonstrates Trina Solar's commitment to vertical integration in module manufacturing, energy storage systems, and mounting system manufacturing. 

Additionally, in 2022, Trina Solar's Yiwu Vertex Super Factory completed a self-evaluation report for green factory certification. This self-assessment showcases the facility's efforts to meet stringent environmental standards and incorporate sustainable practices into its operations. Later, in August 2022, the Yiwu production base successfully completed a third-party evaluation report for Green Factory certification by TiGroup, an EHS certification body, further validating its commitment to sustainable manufacturing. The site is the first factory in the PV industry to be awarded zero carbon status by an independent agency. 

Trina Solar sets the pace for responsible and eco-friendly manufacturing in the solar industry by establishing green factories, obtaining relevant certifications, and partnering with local authorities. 


Energy Consumption Management 

Trina Solar recognizes the critical role of energy conservation in its pursuit of smart and sustainable manufacturing. To ensure efficient resource utilization, the company implements several internal regulations like 

  • the Energy Measurement and Management Procedure 

  • the Energy & Resource Management Procedure 

  • the Energy Review Procedure 

The procedures provide guidelines for energy conservation across our different manufacturing facilities. 

Trina Solar has obtained ISO certifications that validate its efforts in line with its energy management commitment. In 2015, the British Standards Institution (BSI) issued the company  the ISO 50001 Energy Management System Certification. This certification recognizes Trina Solar's adherence to internationally recognized standards for energy management.

Setting and Achieving Energy Conservation Targets 

Trina Solar is dedicated to setting and achieving ambitious energy conservation targets as part of its commitment to sustainable manufacturing.
