Vietnam Solar Energy Market Statistics and Insights

Vietnam Solar Energy Market Insights & Analysis

The Vietnam Solar Energy Market is anticipated to register a 2.02% CAGR during 2026–2034. The market size was valued at USD 800.98 million in 2025 and is projected to reach USD 958.94 million by 2034. Vietnam's solar energy sector has experienced remarkable transformation over the past decade, supported by robust government policy frameworks and international investment inflows. The country's National Power Development Plan VIII (PDP8), approved in 2023, outlines ambitious renewable energy targets, aiming for solar power to constitute over 20% of the national energy mix by 2030.

This strategic direction has catalyzed fresh capital deployment from both domestic enterprises and foreign developers. In 2024–2025, IFC and ADB jointly committed over USD 200 million in financing for distributed solar projects across Vietnamese industrial zones. Such institutional backing has reinforced developer confidence and accelerated project pipelines, positioning Vietnam as Southeast Asia's most active solar destination outside of China.

Vietnam Solar Energy Market Dynamics

Key Market Driver: Robust Policy Support Accelerating Solar Deployment

Vietnam's Feed-in Tariff (FiT) mechanism, though transitioning to competitive auction-based procurement, remains a cornerstone driver of solar investment. The government's FiT regime, which offered rates between USD 0.0709 and USD 0.0838 per kWh for rooftop solar, attracted over 9 GW of rooftop installations between 2020 and 2023. With PDP8 now guiding the sector, the Ministry of Industry and Trade (MOIT) has initiated a direct power purchase agreement (DPPA) framework enabling industrial consumers to procure renewable electricity directly from generators.

This policy evolution is particularly significant for export-oriented manufacturers operating in Vietnam's industrial parks, many of whom face international sustainability compliance requirements, thereby sustaining underlying demand for solar capacity through 2034.

Major Industry Challenge: Grid Infrastructure Lagging Behind Generation Capacity

One of the most structurally significant constraints facing the Vietnam Solar Energy Market is the persistent mismatch between installed generation capacity and transmission infrastructure. Vietnam's northern and southern grid corridors remain inadequately interconnected, leading to chronic curtailment, particularly in the south-central provinces of Ninh Thuan and Binh Thuan, which host over 60% of the country's utility-scale solar assets.

In 2023, curtailment rates at certain projects exceeded 30%, directly eroding investor returns and dampening appetite for new utility-scale development. The state-owned electricity utility EVN has acknowledged transmission gaps but faces fiscal constraints that limit rapid capital expenditure in grid upgrades, creating a structural bottleneck that will persist through the medium-term forecast period.

Emerging Trend Shaping Outlook:Rooftop Solar Expanding Across Industrial Zones

Vietnam's industrial manufacturing sector, driven by global supply chain diversification away from China, is rapidly emerging as the most dynamic demand center for commercial and industrial (C&I) rooftop solar. Foreign-invested enterprises operating in special economic zones, including Samsung, LG, and Foxconn affiliates, are increasingly mandating on-site renewable generation to meet Scope 2 emissions targets under ESG disclosure frameworks.

Berkeley Energy C&I Solutions and Shire Oak International Ltd have both scaled C&I solar portfolios in Vietnam significantly since 2023. This trend is expected to intensify through 2034, particularly as the DPPA mechanism matures and long-term offtake contracts become standardized, unlocking a multi-hundred-megawatt segment of self-consumption solar installations.

Vietnam Solar Energy Market Segment-wise Analysis

Vietnam's solar energy market is segmented across two key dimensions, technology type and grid connectivity, each reflecting distinct adoption patterns, regulatory environments, and investment profiles. Together, these segments offer a granular view of where growth momentum is concentrated and how market participants can position themselves for long-term value capture.

By Technology

• Solar Photovoltaic (PV)
• Concentrated Solar Power (CSP)

Solar Photovoltaic (PV) represents the dominant technology segment, commanding approximately 82% of the total Vietnam Solar Energy Market in 2025. PV's dominance is rooted in its scalability, rapidly declining module costs, and versatility across rooftop, ground-mounted, and floating solar applications. Vietnam's geographic positioning along the equatorial belt provides an average of 4.5–5.5 peak sun hours daily across southern and central regions, making PV installations economically attractive without the need for supplementary storage in most configurations.

Leading module suppliers such as Longi Green Energy Technology Co. Ltd and Trina Solar Co. Ltd have established strong distribution and service networks within the country, supporting the sustained rollout of high-efficiency mono-PERC and TOPCon modules. Concentrated Solar Power (CSP), by contrast, remains nascent, accounting for the remaining share. CSP's high capital intensity and land requirements limit near-term commercial viability in Vietnam, though pilot-scale interest exists for hybrid thermal storage applications in the longer-range outlook.

By Grid Type

• On-Grid
• Off-Grid

On-Grid solar installations account for approximately 78% of total grid-type revenue in 2025. This segment's dominance reflects Vietnam's extensive national grid coverage in urban and semi-urban areas, where industrial and commercial consumers are directly connected to EVN's distribution network and can benefit from net-metering and DPPA arrangements. On-grid rooftop installations across industrial parks have been particularly prolific, with rapid uptake accelerating following the government's net-metering policy revisions.

Off-Grid solar, representing the remaining 22% market share, serves rural electrification needs across Vietnam's highland and island communities where grid extension remains economically unviable. Organizations including Shire Oak International and regional development agencies have funded off-grid micro-grid deployments in provinces such as Dak Nong and Kon Tum, providing energy access to previously unserved populations. While smaller in revenue contribution, the off-grid segment maintains strategic importance as a social infrastructure investment with multi-stakeholder funding support.

Regional Projection of Vietnam Solar Energy Market

Regionally, the Vietnam Solar Energy Market is analyzed across:

• Southern Vietnam
• Central Vietnam
• Northern Vietnam

Southern Vietnam leads the national solar energy market, commanding approximately 48% of total installed capacity and revenue in 2025. The region's advantage stems from superior solar irradiance levels, concentrated industrial infrastructure, and proximity to Ho Chi Minh City's robust commercial demand base. Provinces including Binh Duong, Dong Nai, and Long An host some of Vietnam's densest clusters of export-processing zones, where C&I solar demand has been strongest. Central Vietnam, particularly Ninh Thuan and Binh Thuan, ranks second by installed utility-scale capacity, while Northern Vietnam is accelerating as industrial FDI inflows redirect manufacturing northward.
