Solar energy development in Southern Vietnam presents an exciting opportunity – and a critical need. The region’s robust economic growth, particularly within industrial hubs, demands a reliable and sustainable power supply. Lucky for us, the Southern region enjoys exceptionally favorable conditions for harnessing the sun’s energy. With abundant sunlight and a clear path towards Vietnam’s ambitious renewable energy goals, it’s a prime location for growth. Discover how businesses and policymakers can collaborate to unlock this potential, driving economic prosperity while minimizing environmental impact. Learn more about these crucial developments and what they mean for Vietnam’s future.
The Southern region of Vietnam is exceptionally well-suited for solar energy development, benefiting from abundant sunshine and high solar radiation levels throughout the year. This renewable resource is increasingly recognized as a key driver of sustainable development in the region, offering significant opportunities for clean energy generation.

Favorable conditions for solar development in the South
Vietnam presents a significant opportunity for solar energy development. According to the National Power Development Plan for the period 2021-2030, with a vision to 2050, the country’s solar potential is estimated at approximately 963,000 MW. This includes substantial capacity for ground-mounted (837,400 MW), floating (77,400 MW), and rooftop solar installations (48,200 MW).
A World Bank solar radiation map reveals that solar intensity in Vietnam ranges from 897 to 2,108 kWh/m²/year, equivalent to 2.46 to 5.77 kWh/m²/day. The highest levels of solar radiation are concentrated in the Central Highlands and Southern regions, particularly in provinces like Dak Lak, Gia Lai, Nha Trang, Ninh Thuan, Binh Thuan, Tay Ninh, and Binh Phuoc. These areas are well-suited for maximizing the benefits of solar energy.
The Southern region, including Ho Chi Minh City, enjoys particularly favorable natural conditions. It benefits from abundant sunlight, with annual sunshine hours ranging from 2,000 to 2,600 and substantial solar radiation. For example, Ho Chi Minh City receives an average of 1,581 kWh/m²/year of solar radiation, peaking at 6.3 kWh/m²/day. This high potential extends to rooftop solar, with projections estimating a capacity of 1,589 MWp by 2030, based on the manufacturing enterprise sector alone, as outlined in the Rooftop Solar Development Project in Ho Chi Minh City for 2026-2030.

The adoption of solar energy, particularly rooftop solar, is crucial for the continued growth of the Southern region. This region serves as a key economic engine for Vietnam, home to advanced industrial clusters that account for 30.6% of the nation’s total. The Regional Plan for the Southeast, aiming for an average annual growth rate of 8-9% between 2021 and 2030, necessitates robust energy solutions, and sustainable development provides a sustainable path forward.
Furthermore, provinces in the Southwest region, such as Ben Tre and Ca Mau, are actively incorporating renewable energy sources, including solar, into their long-term development plans. Ca Mau’s plan, for instance, envisions transforming the province into a seafood processing hub and a national renewable energy export center, encouraging self-generating and self-consuming solar power systems.
Solar development solutions for the Southern region
During a scientific conference on “Solutions for the development of the renewable energy industry in the Southern region” organized by the Southern Institute of Social Sciences and the University of Finance – Marketing on December 21, 2023, Mr. An, Pham Dang – Deputy General Director of Vu Phong Energy Group and Director of VP Carbon, shared valuable insights from a business perspective on advancing renewable energy in the Southern region. These insights focused on the importance of supportive government policies, renewable energy certificates (RECs), and fostering strategic partnerships for mutual growth.

The Southern region possesses significant potential for renewable energy, particularly solar energy, especially within industrial and export processing zones. The development of smart, sustainable industrial zones that prioritize automation, efficient production processes, and renewable energy sources can offer businesses enhanced reliability and operational efficiency. Implementing rooftop solar systems for on-site power generation and consumption not only increases local power supply but also reduces the strain on the regional transmission and distribution infrastructure.
To unlock this potential, supportive policies are crucial. These policies should encourage businesses to embrace green energy and optimize energy efficiency through methods like self-consumption of solar power and facilitating direct power purchase agreements (DPPAs). Furthermore, in line with the global push for a green transition, businesses should collaborate to register and trade RECs, driving progress toward 100% renewable energy consumption and maximizing system efficiency. Mr. An also highlighted the importance of development partnerships, such as collaborative research and development initiatives with local institutions and partnerships with global brands to implement cleaner and more efficient technologies.

With the global trend towards green transitions and Vietnam’s commitment to reducing emissions and achieving Net Zero by 2050, solar energy plays a vital role as a key national energy source. Effective policy mechanisms are essential to drive the sustainable development of renewable energy initiatives in the Southern region. A collaborative effort between the government, businesses, and scientific experts is necessary to implement comprehensive and impactful solutions.
