The content was provided by the Ministry of Industry and Trade in the third draft of the Prime Minister's Decision on support policies for households installing self-produced and self-consumed rooftop solar power and electricity storage systems.

Specifically, the Ministry of Industry and Trade proposed that households be supported with 1-1.5 million VND in investment capital for self-consumption rooftop solar power systems. In case of installing a battery storage system (BESS), they will be supported with an additional 1-1.5 million VND.

In addition, households can receive commercial loan interest support for investment, with a maximum term of 3 years. The loan limit with interest support for households without installing an electricity storage system is at least 4 million VND for each 1 kWp of maximum capacity, applicable to the maximum capacity up to 5 kWp.

For households that install an electricity storage system, they will support interest rates with a minimum loan limit of 2 million VND for each 1 kWh of the storage system, limited to a capacity of up to 10 kWh.

The policy is only applicable once per household and may be revoked if the commitment is violated.

Compared to the draft published in July, the financial support level this time is clearly separated between households with and without BESS systems. Previously, the Ministry of Industry and Trade proposed a general support of up to VND500,000 for 1 kWp of installed capacity.

However, the loan limit this time can be up to 40 million VND for a system, including storage equipment. This level is up from the previous expected level of a maximum of 7 million VND for 1 kWp, not exceeding 35 million VND.

Households wishing to receive support must have a system capacity of 1 kWp or more, with storage of 2 kWh. In the case of selling surplus electricity, the household owner must negotiate with the buyer to install a two-way meter suitable for the connected capacity.

According to the Ministry of Industry and Trade, the investment cost for a rooftop solar power system with storage equipment is from 12-15 million VND per kWp, equivalent to about 65-85 million VND for a 5kWp system - the common level that households choose to install. Of which, the storage equipment accounts for about 30-35% of the investment cost.

The country currently has more than 103,000 rooftop solar power projects with an installed capacity of over 9,500 MW. According to the adjusted Power Plan VIII, by 2030, Vietnam aims to have 50% of government offices and 50% of homes installed with self-produced and self-consumed solar power.

Currently, the country has about 103,000 rooftop solar power projects, with a total installed capacity of more than 9,500 MW. According to the adjusted Power Plan VIII, Vietnam aims to have 50% of office buildings and 50% of homes use self-generated and self-consumed rooftop solar power by 2030.

The Ministry of Industry and Trade calculates that the state budget support is expected to be up to 3 million VND per household, with 50% of households (about 14 million households) installing rooftop solar power, the total support value could be up to 42,000 billion VND in the period 2026-2030. Thus, each year the total state budget will have to support about 8,400 billion VND, equivalent to about 250 billion VND per province per year).

However, according to the operator, if each household installs an average of about 3 kWp, the annual electricity production could reach more than 50 billion kWh, equivalent to 16% of the country's electricity demand in 2024.

"With the national power system, these distributed power sources will help reduce investment and operating costs for the transmission grid, the cost of purchasing electricity from higher-priced power sources, and net emissions for the country," the Ministry of Industry and Trade assessed. In addition, this agency also believes that households will benefit from reducing the cost of purchasing electricity from the system, especially households with high consumption in the high price range.
