Rooftop solar power development in Vietnam has yet to meet its target and remains slower than other baseload power sources, Deputy Minister of Industry and Trade Truong Thanh Hoai said at a regular Government press briefing in Hanoi on October 3.

The Government’s Decree 243/2026/ND-CP, dated June 26, 2026, spells out new rules under the Law on Electricity for developing renewable and new energy.

More than 130,000 rooftop solar systems have been installed nationwide, supplying 6.6 billion kWh of surplus electricity to the grid in the first seven months of 2026.

Hanoi households could receive subsidies for rooftop solar and batteries, while national regulators are considering a new approach to solar power pricing that better reflects local conditions.

Turning sunshine into money is gaining momentum as households increasingly invest in rooftop solar systems. Across northern Vietnam, more than 10,000 rooftops are now equipped with solar power systems.

New Government policies and mechanisms are set to broaden investment channels for households and businesses, accelerate distributed power generation, shore up energy security and realise Vietnam's green growth targets.

New rooftop solar regulations that took effect on June 26 allow higher surplus electricity sales in selected cases while maintaining grid safety requirements.

Prolonged heat waves have driven electricity demand sharply higher, especially in the evening.

Vietnam’s electricity regulator has indicated that rooftop solar producers could be permitted to export 100% of surplus power under certain grid conditions.

By installing rooftop solar power coupled with a battery energy storage system, Nguyen Minh Hoang's family in Tuyen Quang cancomfortably use electrical appliances and charge their electric vehicle, while their electricity bills drop sharply.

Besides providing a stable power supply, rooftop solar systems have also enabled many business households to significantly reduce electricity costs, with some cases saving up to VND20 million per month.

A spike in electricity demand amid extreme heat has pushed rooftop solar ahead of wind and biomass, reshaping Vietnam’s power mix in a single day.

The directive underscores the top and urgent priority to ensure safe, stable and uninterrupted power supply for production and daily life is saying that these hold decisive importance for economic growth and national energy security.

The push for energy transition stems not only from market pressure or environmental standards, but also from the need to strengthen the resilience of the economy.

The Ministry of Industry and Trade has unveiled a draft decree that would allow households to sell up to 50% of their rooftop solar output, aiming to boost green energy adoption.

Vietnam’s Ministry of Industry and Trade proposes stiff penalties for rooftop solar projects that bypass regulations or fail to report capacity details.

The Ministry of Industry and Trade (MOIT) has proposed that households installing rooftop solar must notify the commune-level People’s Committee where the power source is installed.

The Ministry of Industry and Trade has released more details about the VND2-3 million cash support for households installing self-produced, self-consuming rooftop solar and the loan support scheme at 8.3 percent/year interest.

In addition to direct financial support of VND2-3 million, the Ministry of Industry and Trade has proposed that households installing rooftop solar systems receive loans with specific subsidized interest rates and defined overdue interest rates.
