Vietnam’s Ministry of Industry and Trade (MOIT) has unveiled a draft proposal outlining new financial mechanisms to promote the deployment of residential solar and energy storage systems designed for self-consumption.
Under the proposed amendment, households installing rooftop solar systems without storage could receive between VND 1 million ($37.97) and VND 1.5 million in direct investment support. Those opting to include battery storage systems would be eligible for an additional VND 1 million to VND 1.5 million, provided the system has a minimum capacity of 1 kW of solar and 2 kWh of storage.
To qualify, households must commit to operating the system for at least three years.
Loan Incentives for Home Solar and Storage
The proposal also introduces preferential loan options, allowing households to borrow up to VND 40 million at an 8.4% annual interest rate with a 36-month repayment term.
Of this amount, up to VND 20 million can be allocated for the installation of rooftop solar systems, with a cap of VND 4 million per kW for systems up to 5 kW in capacity. The remaining VND 20 million can be used for storage systems, capped at VND 2 million per kWh up to 10 kWh of storage capacity.
Implementation and Technical Support
According to the draft, local power utilities will be responsible for providing technical guidance on installation and grid connection, while commune-level authorities will oversee implementation at the community level.
The proposal also specifies the installation of two-way electricity meters to enable households to track consumption and negotiate with buyers for any excess electricity supplied to the grid.
Toward 2030 Self-Consumption Targets
Vietnam’s broader energy strategy aims to have 50% of office buildings and 50% of residential homes powered by self-produced and self-consumed rooftop solar by 2030.
The MOIT said this initiative is expected to reduce the strain on local and national grids, lower state investment pressure, and improve land-use efficiency for residential properties.
If approved, the new financial mechanisms would take effect from early 2026 through the end of 2030. The draft proposal has been submitted to the Ministry of Justice for review.
Vietnam’s Solar Progress
According to data from the International Renewable Energy Agency (IRENA), Vietnam’s cumulative installed solar capacity reached 18.66 GW by the end of 2024, with around 79 MW added that year.
Most of this capacity was developed under the now-expired feed-in tariff (FiT) program, which supported both small-scale and utility-scale installations. In September 2024, the government introduced a net-metering scheme for rooftop solar—limiting grid exports to 20% of total output—and in April 2024, new feed-in tariffs were released for utility-scale solar plants.
