# Vietnam Solar Rooftop and Energy Leasing Market --- ## Market Overview # CHAPTER 1 - Market Overview The Vietnam Solar Rooftop and Energy Leasing Market combines upfront engineering, procurement, and construction revenue with recurring energy-service income from leases, on-site PPAs, monitoring, and O&M. Industrial customers represented 51.59% of EVN commercial electricity sales in 2024, creating high-value daytime loads where self-consumption savings can support bankable long-tenor contracts and multi-site portfolios. Demand is concentrated in the southern industrial corridor linking Ho Chi Minh City, Binh Duong, Dong Nai, and Long An, alongside northern export hubs around Bac Ninh and Hai Phong. Vietnam had 422 industrial zones across 61 provinces and cities by April 2024. Cluster density reduces customer acquisition, engineering standardization, interconnection, and maintenance costs for scaled operators. The regulatory framework changed materially through Decree 58/2025 and Decree 243/2026. The June 2026 amendment increased the permitted sale of surplus self-produced rooftop solar from 20% to 50%, with higher sales possible through December 2030 where local grids can absorb output safely. This improves sizing flexibility and widens monetization beyond strict self-consumption. Vietnam moved from policy design to commercial execution when the first grid-based DPPA transaction started on June 1, 2026. A 49 MWp solar plant is expected to supply about 70 GWh annually to a large electronics manufacturer and reduce approximately 46,000 tonnes of carbon dioxide. The milestone strengthens corporate procurement confidence and contract standardization. ## KPIs at a Glance * Market Value: USD 780 Mn (2025) * Dominant Region: Southern industrial corridor * Dominant Segment: Commercial & Industrial Rooftop Solar EPC (fastest growing: third-party leasing and on-site PPA) * Total Number of Players: 19 ## Future Outlook The Vietnam Solar Rooftop and Energy Leasing Market is projected to expand from USD 780 Mn in 2025 to USD 2,158 Mn by 2031, representing an 18.5% forecast CAGR.

Annual installed or contracted activity is modeled to exceed 5,600 MWp by 2031. The base case assumes effective implementation of Decree 243, continued industrial electricity growth, improving contract standardization, and adequate grid hosting capacity. **Data used:** 18.5% forecast CAGR (2026-2031); 5,608 MWp annual activity (2031). **So what:** Winning platforms need financing and asset-management capabilities in addition to EPC capacity. #### Q: Where is the profit pool shifting within the market? **A:** The profit pool is shifting from purely upfront EPC billing toward recurring leasing, on-site PPA, O&M, monitoring, and storage-linked services. Commercial and industrial EPC remains the largest revenue pool because factory projects carry larger ticket sizes and higher roof utilization. However, third-party ownership is expanding faster because it removes customer upfront capex and supports longer customer relationships. The modeled leasing and DPPA revenue share rises from 23.1% in 2025 to 34.5% by 2031, improving revenue visibility while increasing credit and refinancing requirements. **Data used:** 23.1% leasing and DPPA share (2025); 34.5% share (2031). **So what:** Operators should build credit underwriting, contract administration, and portfolio refinancing as core capabilities. #### Q: What changed under Decree 243/2026? **A:** Decree 243/2026 amended the renewable and DPPA framework established by Decrees 57/2025 and 58/2025. It increased the ordinary permitted sale of surplus self-produced rooftop solar from 20% to 50% of output. Through December 31, 2030, parties may agree to sell more than 50% where the local grid can receive the electricity safely. The decree also broadens eligible large users and cluster retailers, recognizes storage-charged rooftop output, supports two DPPA routes, and removes a registration step for certain direct-sale rooftop projects. **Data used:** 50% ordinary surplus-sale cap (2026); conditional higher sales through December 31, 2030. **So what:** Developers can optimize systems more flexibly, but must still prove grid compatibility and licensing compliance. #### Q: What is the biggest structural risk for developers and lenders? **A:** The largest risk is the interaction of policy bankability, site-level load matching, and grid flexibility. Legacy renewable tariff disputes have shown that regulatory interpretation can affect lender confidence, while rooftop projects depend on actual self-consumption and interconnection conditions. In March 2025, investors warned that proposed retroactive reviews could affect more than USD 13 Bn of renewable investment. Developers therefore need conservative generation assumptions, clear change-in-law clauses, creditworthy offtakers, monitoring data, and reserve accounts for curtailment, equipment replacement, and contract enforcement. **Data used:** More than USD 13 Bn investment exposure (2025); 28 investor signatories (2025). **So what:** Financing models should price policy and grid risk explicitly rather than relying on headline irradiance. #### Q: How does Vietnam compare with other ASEAN rooftop and leasing markets? **A:** Vietnam is estimated to rank second within the selected peer set of Thailand, Malaysia, the Philippines, and Indonesia by 2025 market size. Its advantage is the combination of a large export-manufacturing base, dense industrial zones, approximately 9,500 MWp of operating rooftop capacity, and an increasingly operational DPPA framework. Indonesia offers a larger long-run addressable load but earlier policy maturity, while Thailand remains larger in current revenue. Vietnam's 18.5% forecast CAGR is above the weighted peer average, supporting a growth-leader position. **Data used:** 2nd peer ranking (2025); 18.5% Vietnam CAGR versus 16.1% weighted peer average. **So what:** Regional investors can use Vietnam as a scalable C&I platform while diversifying policy exposure across ASEAN. #### Q: Which capabilities are required to win in this market? **A:** Winning operators need integrated origination, roof and load assessment, credit underwriting, engineering, equipment procurement, interconnection management, financing, monitoring, O&M, and asset management. Scale alone is insufficient because distributed portfolios contain many contracts, roofs, meters, and counterparties. Firms also need BESS design, cybersecurity, safety compliance, and performance-guarantee capability as projects become more complex. The most defensible platforms will standardize contracts and technical designs across industrial parks while preserving site-level accuracy and maintaining access to long-tenor debt and equity capital. **Data used:** 422 industrial zones (2024); 10,000-16,300 MW BESS target (2030). **So what:** Strategy teams should prioritize integrated platforms over installers competing only on module and labor pricing. --- ## Table of Contents # CHAPTER 14 - Table of Contents ## Market Assessment Phase ### 1.
