To strengthen collaboration with its strategic partner Rang Dong Light Source & Vacuum Flask JSC (“Rang Dong”) and jointly expand the clean energy market in Southeast Asia, Q-SUN recently dispatched a team of technical experts to Vietnam to conduct a large-scale training session on photovoltaic (PV) module technology and applications. The event attracted over 100 core sales personnel from Rang Dong to attend in person, while more than 2,000 members of its nationwide sales network joined online. The training received enthusiastic feedback from all participants.


一、Partnering with Industry Leaders to Build a Model of Cooperation
Founded in 1961, Rang Dong is a leading enterprise in Vietnam’s lighting industry and is listed on the Ho Chi Minh City Stock Exchange. With strong brand influence and market share, Rang Dong has long held a top position in the domestic market. As one of Vietnam’s most powerful and diversified corporations, Rang Dong continues to lead in lighting and electrical manufacturing. Leveraging its solid reputation and government trust, the company has become a core participant in Vietnam’s national “Smart Green Energy City” program, actively supporting the government’s renewable energy initiatives and undertaking major national infrastructure projects.

In recent years, Rang Dong has capitalized on its extensive experience in large-scale government engineering projects and strong financial capacity to expand into solar energy, demonstrating strong momentum in the PV field. The deep collaboration between Rang Dong and Q-SUN marks a new milestone in Q-SUN’s expansion into Vietnam’s high-end photovoltaic market, highlighting Q-SUN’s growing brand strength and technological influence across Southeast Asia.
二、Comprehensive Training to Empower the Vietnamese Market
Focusing on the specific needs of the Vietnamese market, the training program covered two main modules:
Product & Technology Training:
The Q-SUN technical team introduced Rang Dong’s sales team to the TOPCON technology-based MERCURY Series high-efficiency PV modules, including product features, core advantages, and application scenarios. A live demonstration showcased the innovative glass-fiber alloy composite frame, featuring superior insulation, corrosion resistance, and compressive strength—ideally suited to Vietnam’s hot and humid climate—providing reliable and durable solutions for local PV projects.
EPC & System Design Training:
Tailored for Rang Dong’s EPC (Engineering, Procurement, and Construction) team, Q-SUN shared the latest power plant design concepts and system solutions from China. Through real-world case studies, the training dissected key technical aspects of PV plant construction and offered in-depth insights based on Vietnam’s regulatory and environmental context. This systematic training helped the Rang Dong team gain a comprehensive understanding of Q-SUN’s products and technology ecosystem, laying a solid foundation for future cooperation.


三、High-Efficiency Modules Power a Greener Future for Vietnam
Q-SUN’s TOPCON-based MERCURY Series modules deliver high conversion efficiency and superior durability, maintaining stable performance even under tropical conditions. Their outstanding power output and environmental adaptability make them particularly suitable for industrial parks, commercial rooftops, and distributed solar projects in Vietnam. By offering reliable and high-performance solutions, Q-SUN supports Vietnam’s transition to clean energy and promotes the sustainable development of the local PV industry.\

四、Working Hand in Hand to Open a New Chapter in Regional Cooperation
As one of the fastest-growing solar markets in Southeast Asia, Vietnam continues to foster a favorable policy environment with enormous potential in distributed and commercial rooftop PV projects. The large-scale training event led by Q-SUN’s technical team not only demonstrated the company’s technological strength and service capabilities in high-efficiency modules and system integration but also reaffirmed its long-term commitment to promoting global green energy adoption. Looking ahead, Q-SUN will remain dedicated to its mission of “Winning trust with quality, creating value with technology,” and will continue working closely with partners like Rang Dong to make clean energy more accessible worldwide.
