As we step into 2025, Vietnam’s rooftop solar policy is attracting significant attention, with the Ministry of Industry and Trade currently gathering feedback on the draft amendments to Decree 57 and Decree 58/2025.
These updated regulations will directly shape the development of rooftop solar and the "self-generation – self-consumption" model in the coming years. Amid the accelerating energy transition, many households are asking: What changes will the 2025 rooftop policy bring, and how will it impact those wanting to install rooftop solar?
Rooftop Solar 2025 – A New Landscape for Household Solar
Vietnam witnessed explosive rooftop solar growth in 2019–2020 thanks to the FIT mechanism. However, rapid expansion also led to grid overload, inconsistent installation quality, and challenges in grid connection management. The draft 2025 rooftop solar policy aims to regulate the market more sustainably by improving transparency in technical standards, strengthening grid-connection requirements, and encouraging self-consumption models.
Overall, the direction of Rooftop Solar 2025 can be summarized in three key points: safer – more efficient – more aligned with real-world operations, replacing the previous era of rapid expansion driven by FIT incentives.
Management requirements may be categorized more clearly by connection types, making solar more accessible for households.
How the 2025 Rooftop Solar Policy May Affect Households
According to Vietnamnet, the Ministry of Industry and Trade is considering simplifying procedures for self-generation – self-consumption rooftop systems. Management requirements may be categorized more clearly by connection types, making solar more accessible for households.
One notable proposal in the 2025 rooftop policy is to increase the allowable exported electricity ratio from 20% to 50%, offering households a better chance to recover their investment if excess electricity is produced. However, the buying price will likely follow the previous year’s average market price, meaning there will no longer be a fixed preferential FIT rate. As a result, installing rooftop solar for self-consumption remains the most effective model.
Technical safety requirements are also expected to tighten, ensuring stable system performance and safe grid operation, a reasonable step for long-term rooftop solar development. Guidance for Households Considering Rooftop Solar in 2025
Optimize for self-consumption
Assess daytime electricity demand to choose the right system size.
Choose a reputable installer
A rooftop solar system must follow proper technical standards, including fire safety, waterproofing, and certified equipment.
Run clear financial calculations
Even without FIT-style preferential buyback rates, the self-consumption model still offers a practical payback period of 4–7 years, depending on usage.
