BANGKOK, Thailand – June 30, 2026 – LONGi Green Energy Technology Co., Ltd. (“LONGi”), a world-leading solar technology company, announced today that it has signed a Strategic Partnership Agreement with Thai Solar Energy Public Company Limited (“TSE”), a prominent renewable energy developer in Thailand. Under the agreement, LONGi will serve as a strategic module partner, supplying its proprietary BC series high-efficiency solar modules for TSE’s large-scale Solar Big Lot project portfolio.
This partnership builds on a foundation of mutual trust established through prior collaboration. In 2021, LONGi supplied modules for TSE’s floating PV project in Saraburi Province — the first floating solar project in the province. The new strategic agreement elevates their relationship from project-level cooperation to a long-term strategic alliance.
LONGi’s BC series modules, built on advanced back-contact cell technology, deliver higher conversion efficiency, better temperature coefficient, and enhanced reliability — making them particularly well-suited for Thailand’s hot and humid tropical climate, and ensuring stable long-term power generation and investment returns for the project.
“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,” said Dr. Kathleen Malanon, Chief Executive Officer of TSE.
Committed to its mission of “making the best of solar energy to build a green world,” LONGi remains dedicated to technological innovation. The company will continue to support the energy transition and green development of Thailand and Southeast Asia with high-efficiency, reliable products and services.
