LONGi and TSE: A Strategic Alliance for Solar Power in Thailand (2026)

LONGi Green Energy Technology Co., Ltd. has recently signed a strategic partnership agreement with Thai Solar Energy Public Company Limited (TSE) to supply its high-efficiency BC series solar modules for TSE’s large-scale Solar Big Lot project portfolio. This partnership marks a significant milestone in the renewable energy sector, as it showcases the potential for clean energy adoption in Southeast Asia and highlights the importance of technological innovation in the industry.

The agreement builds upon a previous collaboration between the two companies, which began in 2021 when LONGi supplied photovoltaic modules for TSE’s floating solar project in Thailand’s Saraburi Province. This initial project was a groundbreaking achievement, as it was the province’s first floating PV installation, demonstrating the potential for solar energy to be harnessed in innovative ways.

The new partnership expands the relationship from individual project cooperation to a long-term strategic alliance. Under the agreement, LONGi will act as TSE’s strategic module partner, providing its proprietary BC series modules featuring advanced back-contact cell technology. These modules offer several key advantages, including higher conversion efficiency, improved temperature performance, and enhanced reliability, making them well-suited for Thailand’s hot and humid climate.

Dr. Kathleen Malanon, Chief Executive Officer of TSE, expressed confidence in the partnership, stating, "LONGi is a globally recognized photovoltaic leader, and the technological strength and reliable quality of its BC module products are well known. We are confident that this strategic partnership will provide solid equipment and supply security for our large-scale project portfolio, supporting TSE’s sustainable growth objectives."

LONGi’s commitment to clean energy adoption through technological innovation is evident in this partnership. The company believes that this collaboration will support Thailand’s energy transition and the broader renewable energy growth across Southeast Asia. This aligns with LONGi’s mission to advance clean energy adoption and highlights the importance of partnerships in driving technological advancements in the renewable energy sector.

In conclusion, the strategic partnership between LONGi and TSE is a significant development in the renewable energy industry. It demonstrates the potential for clean energy adoption in Southeast Asia and underscores the importance of technological innovation and collaboration in driving the transition to a sustainable energy future. As the world continues to seek cleaner and more sustainable energy sources, partnerships like this one will play a crucial role in shaping the future of the renewable energy sector.
