Vietnam Solar Capacity Hits 19 GW: Lessons for India
⚡ Quick Read
- What happened: Vietnam’s cumulative solar capacity reached 19,252 MW by the end of 2025, adding 586 MW last year.
- Why it matters: The market shift toward C&I rooftop solar and direct power purchase agreements (DPPA) offers a blueprint for Indian developers navigating similar grid and policy constraints.
- Watch: Future growth hinges on the proposed increase in grid-export caps for rooftop solar and continued privatization of the electricity market.
Background and Context
Vietnam’s solar energy landscape has undergone a significant transformation, with cumulative solar capacity reaching 19,252 MW by the end of 2025. According to the latest data from the International Renewable Energy Agency (IRENA), the nation added 586 MW of capacity last year. While this growth rate is a deceleration from the 1.6 GW surge witnessed in 2023, it underscores a maturing market transitioning from rapid, policy-driven expansion to a more sustainable, demand-led model.
Key Details
Analysts from Ember highlight that the current growth is primarily driven by the commercial and industrial (C&I) rooftop solar segment. Unlike utility-scale projects, which face hurdles such as entrenched fossil fuel generation and grid infrastructure limitations, rooftop solar is gaining traction among multinational brands seeking to meet Scope 2 emission commitments. Furthermore, the availability of low-cost solar modules—bolstered by Chinese manufacturing investments within Vietnam—has kept the project economics attractive despite declining feed-in tariffs.
A pivotal development in early 2025 was the introduction of a direct power purchase agreement (DPPA) mechanism. This policy breaks the long-standing monopoly of Vietnam Electricity (EVN), allowing renewable energy generators to sell power directly to large private consumers. Additionally, the Ministry of Industry and Trade is considering a draft decree to increase the grid-export limit for rooftop solar owners from 20% to a higher threshold, a move expected to catalyze further adoption in 2026.
What This Means for EPCs and Developers
For Indian EPC contractors and solar developers, the Vietnamese experience offers critical insights into market evolution. The shift toward battery-integrated solar projects, supported by new tariff structures, mirrors the growing interest in BESS-integrated solar in India. Developers operating in both regions should note that grid curtailment and system flexibility remain the primary bottlenecks. The successful implementation of a DPPA mechanism in Vietnam serves as a potential case study for Indian states looking to enhance the bankability of open-access solar projects.
What Happens Next
Looking toward 2030, Vietnam aims to reach 73 GW of installed solar and 38 GW of onshore wind capacity. Achieving these targets will require significant investment in grid infrastructure and system flexibility. As India continues to scale its own renewable energy sector, the focus on balancing utility-scale capacity with decentralized C&I solutions and private-sector-led PPAs remains essential for maintaining the momentum of the energy transition.
