HCMC – The Ministry of Industry and Trade has proposed that households installing rooftop solar power systems with storage be granted up to VND3 million along with preferential access to loans for three years.
The Ministry of Industry and Trade announced on its official portal that it is drafting a set of new policies to promote household adoption of rooftop solar power systems with storage.
In the third draft, each household may receive VND1-1.5 million for installing rooftop solar power for self-consumption. If a battery energy storage system (BESS) is added, the support increases by another VND1-1.5 million, bringing the total to VND2-3 million.
In addition to those subsidies, households will also be eligible for preferential interest rates on commercial loans for up to three years.
For systems without storage, households can access interest-subsidized loans of at least VND4 million per 1 kWp of maximum capacity. For systems with storage, the supported loan amount is VND2 million per kWh.
The total support can reach up to VND 40 million for one system, much higher than the proposal made in July.
To qualify for those subsidies, rooftop solar systems must have at least 1 kWp of capacity, and storage units must be 2 kWh or more. Each household can only benefit once, and the support may be withdrawn if commitments are breached.
Calculations show that a 5 kWp rooftop solar system with storage currently costs between VND65-85 million, with the storage unit alone accounting for 30-35% of the total investment.
The state budget is expected to provide up to VND3 million per household, and with an estimated 14 million households joining between 2026 and 2030, the total funding could reach VND42 trillion, or an average of VND8.4 trillion per year.
The Ministry of Industry and Trade expects that if households install rooftop solar systems averaging 3 kWp, annual output could surpass 50 billion kWh, about 16% of Vietnam’s 2024 electricity demand.
Beyond easing pressure on transmission investments, the policy would also lower power bills for households, particularly those with higher electricity usage.
