Vietnam's Solar Capacity Soars Past 19 GW: What the Future Holds

Update Vietnam's Solar Boom: A Record-Breaking Capacity As of the end of 2025, Vietnam's solar capacity stands at an impressive 19,252 MW, according to the International Renewable Energy Agency (IRENA). This represents a significant growth of 586 MW compared to the previous year and illustrates Vietnam's rapid ascent within the global renewable energy sector. Interestingly, this increase, however, marks a decline from the peak expansion seen in 2023, where 1.6 GW were added. The substantial growth between 2023 and 2025 shows a shift in the dynamics of solar energy development in the country. Contextual Challenges: Navigating the Energy Landscape Energy analysts Lam Pham and Alnie Demoral at Ember have pointed out that while rooftop solar systems excel, especially among commercial and industrial entities, utility-scale solar projects face a host of obstacles. These include entrenched fossil fuel interests, intermittent issues in renewable energy generation, and resistance from utilities, which have historically favored traditional energy setups. The steep initial investment costs also continue to make the scaling of utility solar more complex. This struggle points toward a reality many nations face: energy transition is not just a technological shift, but a multifaceted transformation involving economic, political, and social factors. Policy Moves: Changing the Game for Solar Energy Last year, Vietnam's government illustrated its commitment to solar energy by updating feed-in tariff rates for solar and wind projects. This included introducing new tariffs for solar projects supplemented by battery energy storage. Over recent years, these tariffs have been on a downward trend, reflecting the global decrease in solar panel prices due to substantial production in China and enhanced competition. In a bid to encourage greater solar energy uptake, a new draft decree proposes that rooftop solar owners could sell up to 50% of their generated energy back to the grid, a significant increase from the current cap of 20%. Analysts argue that this change could substantially stimulate demand in 2026, fostering the country's cleaner energy aspirations. The Direct Power Purchase Agreement: A Landmark Development Furthermore, the introduction of direct power purchase agreements (DPPAs) allows renewable energy generators to sell their power directly to large consumers, breaking the historical monopoly held by Vietnam Electricity. This mark of privatization in the sector is crucial as it opens the doors for private investment and could lead to more efficient energy pricing and procurement strategies. With the country aiming for 73 GW of installed solar and 38 GW of onshore wind capacity by 2030, these policy shifts may play a pivotal role in shaping Vietnam's renewable energy future. Future Gains: The Road Ahead for Vietnam's Solar Market According to projections, Vietnam's solar market could reach a cumulative capacity of around 45,977 MW by 2033, with a compounded annual growth rate (CAGR) of 11.8% anticipated during this period. This growth trajectory is propelled by a strong societal demand for cleaner energy, the burgeoning manufacturing sector, and the long-term sustainability tenets that many multinational corporations are now prioritizing in their operational strategies. As the market transitions away from feed-in tariffs towards more market-driven approaches like competitive power purchase agreements, the landscape is set to encourage not only investment but also innovation in the sector. The rise of corporate renewable procurement can thus bolster energy security and sustainability, signifying that the Vietnamese solar market is truly at the precipice of substantial growth. Conclusion: Embracing Sustainable Energy Solutions With a clear shift towards eco-friendly power sources and organizations increasingly seeking renewable energy options, it’s imperative for stakeholders, from policy makers to industry players, to embrace and navigate the complexities of this evolving landscape. By remaining flexible and adaptive, Vietnam can lead by example in the global journey toward sustainable energy.
