Tiếng ViệtAs industrial parks continue to expand production capacity and electricity consumption rises, ensuring a stable power supply has become a significant challenge. In this context, rooftop solar is increasingly recognized as an on-site power generation solution, enabling enterprises to gain greater operational control while paving the way for the development of green and sustainable industrial parks.
Significant Potential Yet to Be Fully Utilized
Vietnam currently has 431 industrial parks (IPs) and over 1,000 industrial clusters, with strong expansion expected in the coming years. This provides a solid foundation for deploying large-scale rooftop photovoltaic (PV) systems, leveraging available factory roof space.
During 2024–2025, rooftop solar installations in industrial parks have grown rapidly, reaching a total capacity of over 3,200 MWp. Notably, approximately 25% of systems have integrated Battery Energy Storage Systems (BESS), indicating a shift toward more advanced and flexible energy solutions. The Southern region leads deployment, accounting for over 55% of installed capacity, driven by favorable solar irradiance and well-developed industrial infrastructure.
However, current deployment remains below its full potential. By 2030, rooftop solar capacity in industrial parks is projected to reach 20,000 MWp. Achieving this target will require addressing several existing bottlenecks.
Dual Benefits: Cost Reduction and Competitive Advantage
Investing in rooftop solar offers tangible benefits for enterprises in industrial parks. First, it enables reduction in electricity costs, particularly during peak daytime hours when production demand is highest. In addition, the use of renewable energy improves corporate carbon footprint profiles, helping businesses meet increasingly stringent environmental requirements from international partners. This is a critical factor as global supply chains increasingly prioritize sustainability commitments.
From a macro perspective, rooftop solar also helps reduce pressure on the national grid, minimizing the need for investment in conventional power generation and transmission infrastructure.
Barriers: Infrastructure, Capital, and Policy Framework
Despite strong potential, rooftop solar deployment in industrial parks faces several challenges. A primary barrier is the high upfront capital expenditure (CAPEX), especially when integrating energy storage systems. Many small and medium-sized enterprises (SMEs) lack sufficient financial capacity to invest, while access to financing remains limited due to collateral requirements and relatively high interest rates.
Additionally, grid infrastructure in some regions has not kept pace with development, and electricity pricing mechanisms and support policies are still evolving. These factors have led to delays or stalled implementation of many potential projects.
Policy Development – The Key to Market Acceleration
To unlock the full potential of rooftop solar in industrial parks, experts emphasize the need for a clear and stable regulatory framework, along with supportive financial mechanisms. Policies that incentivize the adoption of energy storage systems (BESS) are particularly important, as they enhance energy utilization efficiency and reduce grid dependency.
Furthermore, strengthening public-private partnerships (PPP) and encouraging participation from international organizations will help mobilize capital and transfer expertise in clean energy deployment.
Toward a Green Industrial Ecosystem
Rooftop solar is not merely an energy solution—it is a foundational element in building a green industrial ecosystem, where production is aligned with environmental protection and efficient resource utilization.
In the context of Vietnam’s commitment to achieving net-zero emissions by 2050, renewable energy development within industrial parks will play a critical role. When integrated with energy storage and smart energy management systems, rooftop solar will contribute to a resilient and sustainable energy infrastructure, supporting long-term economic growth.
