Rooftop solar policy in Vietnam: Directive 10/CT-TTg and MOIT guidance

According to information published by MOIT, the directive links electricity saving with self-production, self-consumption rooftop solar combined with suitable storage, so power is supplied locally and the grid gains flexibility.

• Save at least 3% of total national electricity consumption in 2026.
• Save at least 10% during the peak months from April to July.
• Priority groups: public offices, production, business and service facilities, and households.
• Rooftop solar combined with battery energy storage (BESS) is encouraged.
• Direction of roughly 10% of public offices and 10% of households installing each year, or 20% of planned rooftop capacity over 2026–2030.

These figures are policy management targets stated in the directive as published by MOIT, not guaranteed output or financial incentives for any individual project.

MOIT issued Official Letter 7404/BCT-DL urging provinces to develop self-production, self-consumption rooftop solar, including allocating investment plans and funding for public offices, schools and hospitals.

• Provinces prepare investment plans and budget for installations at offices, schools and hospitals.
• Tasks assigned under Directive 10/CT-TTg are to be completed before 31 March 2027.
• Provincial people's councils are asked to consider support policies for households.
• EVN coordinates initial grid connection checks and ongoing compliance under Decree 58/2025/ND-CP.

For a business, the practical value is not a cash incentive but a clearer legal framework and more proactive local utilities guiding connection and operation of self-consumption systems.

• Procedures are handled more consistently under Decree 58/2025/ND-CP, reducing schedule risk from paperwork.
• The policy direction favours on-site consumption and limits export, so capacity must match daytime load.
• Storage is encouraged, which suits plants with load shifted away from solar hours or peak demand charges.
• Companies whose renewable demand exceeds available roof area can also look at the DPPA mechanism.

• Review building legal records: construction permit, roof condition, fire safety documentation.
• Measure and analyse daytime load to size capacity without unwanted export.
• Check metering limits and the connection voltage level before fixing system size.
• Decide the financing route: self-investment, roof lease or a zero-capex ESCO model.
• Plan emissions reporting if ESG, RE100 or supply-chain requirements apply.
