LONGi and SEV: Pioneering Sustainability in Vietnam's Garment Industry

Hanoi, Vietnam – In September 2024, LONGi and Solar Electric Vietnam JSC (SEV) delivered an advanced solar photovoltaic (PV) project to Tan De Company, one of Vietnam's largest garment manufacturers and exporters. The project, involving the installation of 11 MWp of solar PV rooftop systems across nine factories, is set to generate 12,603 MWh annually and reduce 8,527 tons of CO2 emissions annually. This initiative not only aligns Tan De with international green manufacturing standards but also advances Vietnam's renewable energy goals and showcases the role of sustainable practices in the textile and manufacturing industries.


The annual energy generation of 12,603 MWh translates to significant cost savings for Tan De Company. With the solar rooftop systems, the company can reduce its reliance on grid electricity, lowering its energy expenses. Moreover, the reduction in CO2 emissions of 8,527 tons annually impacts Tan De Company's environmental compliance costs and reputation positively. By embracing clean energy, the company demonstrates its commitment to sustainability, enhancing its attractiveness to environmentally conscious investors and customers.

In addition to cost savings and improved reputation, Tan De Company has the potential to generate revenue from selling excess solar energy back to the grid. This revenue stream, while dependent on local policies and grid interconnection regulations, can provide an additional source of income for the company.


The scale and success of this project influence Vietnam's renewable energy targets and grid integration. As more companies adopt solar PV systems, the demand for renewable energy increases, driving the expansion of the country's renewable energy infrastructure. Furthermore, the project's resilience during natural disasters like Typhoon Yagi enhances its value and relevance in the global solar market. The high-quality installation and engineering capabilities demonstrated by SEV establish Tan De as a leader in green manufacturing in Vietnam, contributing to the garment industry's sustainability and international competitiveness.

The collaboration between LONGi and SEV in this project impacts their market position and future growth opportunities in Vietnam and the global solar market. By successfully delivering advanced solar PV projects, the companies strengthen their reputation and expand their customer base. This project serves as a testament to their capabilities and commitment to promoting green energy and sustainable development, positioning them well for future growth in the solar market.
